McVetty, North Tonawanda, N.Y., assignor to The Wurlitzer Company, Chicago, 111., a corporation of Ohio Filed Nov. 16, 195?, Ser. No. 853,159 16 Claims. (Cl. 194-15) The present invention relates to coin controlled phonographs and more particularly to coin controlled means for controlling the selection of records for playing by an automatic phonograph.

One object of the invention is to provide new and improved coin controlled means for controlling the selection of records for playing by an automatic phonograph.

A further object is to provide improved, coin activated, phonograph control means which is inherently well adapted for controlling the selection of records by a phonograph from a remote control station.

Another object is to provide for controlling the operation of an automatic phonograph, new and improved coin controlled means in which the setting of selector buttons in accordance with the balance of established credit, the reception of coins into the control means, the cancellation of credit upon selection of a record for playing, and the generation of record selecting electrical impulses are all accomplished by operation of a single electric motor.

A further object is to provide an improved phonograph control as recited in the preceding objects in which the functions listed in the preceding objects, together with the establishment of credit in accordance with the value and denomination of coins deposited in the control means and the cancellation of credit for individual records selected in accordance with the different playing price schedules of different records selected for playing are all accomplished by the operation of a single electric motor with the aid of a single crediting solenoid.

An additional object is to provide new and improved phonograph control means as recited in the preceding objects which is inherently reliable in operation and well adapted for manufacture on a mass production basis.

The improved phonograph control means provided by the invention is particularly well suited for controlling operation of. an automatic phonograph 10 from a remote control station or Wall box 12 connected to the phonograph by a cable 14 as shown in FIG. 1.

The connecting cable 14 comprises only three wires.

The wall box 12 is energized from the phonograph 10 through two wires 16, 18 of the cable and the selection of records for playing by the phonograph 10 is controlled by record selecting electrical pulses transmitted from the wall box to the phonograph through the third wire 20 of the' cable, FIG. 16.

As will presently appear, the phonograph control provided by the invention is adapted to control the selection of records from two different categories of records which are priced differently for playing. Moreover, the control operates automatically to charge the player for the records selected in accordance with the playing piice of the respective records.

The records available for playing are stored in the phonograph 10 and listed on title strip holders 22 in the wall box 12 in accordance with the playing price of the individual recordings.

The player deposits coins in a coin slot 24 in the Wall box 12 and makes selections of records for playingv by depressing one of a series of letter buttons 26 and one of a series of number buttons 28 on the wall box.

The wall box 12 must operate automatically to perform and correlate with each other a number of complex functions, including those which are listed as follows:

(1) Automatic establishment of credit to the player for the value of the coins deposited and the automatic award of bonus credit for the depositing of coins in the larger denominations as an inducement to the depositing of the larger coins.

(2) Automatic control of the operation of the selector buttons in accordance with the relationship of the established credit to the prices charged for playing different records.

(3) Automatic response to the depressing of a letter button and a number button to produce a sequence of record selecting control pulses which enable the phonograph to differentiate between and properly select any one of the selections available for playing in the machine.

(4) Automatic selection of records for playing from different categories of records, which are priced differently for playing, and automatically making charges for the records selected in accordance with the playing price of the respective records.

(5) Automatically control the deposited coins in a manner to assure proper crediting for each coin deposited.

. complishes all of the above listed functions by operation of a single motor aided by the action of a single crediting solenoid.

Having reference to the drawings in greater detail, coins deposited into the slot 24, FIG. 1, are received into a slug rejector 30 of conventional construction, FIGS. 2 and 7, which directs the individualcoins into a crediting zone 32 to occupy positions in the zone corresponding to the denomination of the respective coins. The instant control is adapted to receive coins in the denominations of 5, and 50 and is provided with four coin sensing switches 34, 36, 38 and 40, equipped respectively with four coin sensing actuators 42, d4, 46 and 48, extending into the crediting zone 32 for operation by coins moving into the crediting zonein the respective denominations mentioned above.

Coins in the denomination of 5d engage the actuator 42, to momentarily close the switch 34 and drop 'on through the crediting zone '32, into an underlying cash box (not shown). The brief closing of the switch 34 operatesin a manner-to he described presently to establish one unit ofcredit in the control.

Coins in denominations larger than 5, which enter the crediting zone 32, are supported in the crediting zone by a transverse support barSO projecting laterally from the medial portion of a combined coin release and credit cancelling lever 52, FIGS. 6, 7 and 8. FIGURE 6 illustrates the position in which a 50 coin 54 is supported in the crediting zone 32 by the coin support bar 50.

As previously intimated, closure of any one of the coin sensing switches 34, 36, 38 and 40 operates to establish playing credits in accordance with a value scheduled which gives credit for both the value and the denomination of the coins deposited; Moreover, as will presently appear, provision is made for varying the schedule of playing creditsestablished in response to the depositing of coins of ditferent denominations.

Playing credits are established and accumulated by the incremental rotary displacement of an accumulator wheel 56 FIG. 8, in a crediting direction away from its no credit or zero balance position. The accumulator wheel- 56 is continuously urged rotatably in its crediting direction by a tension spring 58 anchored to a bracket 60 and connected to a rotary support .62 for the wheel, as shown in FIGS. 3, 6 and,9. accumulator Whl56 in a crediting direction is etfected by cyclic operation of a double ended escapement pawl 64, FIG. 8, medially pivoted on a stud 66to coact with the serrated periphery 68 of the wheeL A crediting sol noid 70 connected with the escapement pawl 64 operates the pawl to effect movement of the wheel 56 by the spring 58 through an increment of movement corresponding to, one credit unit, in response to a single energization of the crediting solenoid.

As will be explained in greater detail, closing of the coin sensing switch 34 in response to the depositingofa 5 coin effects a momentary energization of the crediting solenoid 70 which effects displacement of the wheel 56 by one credit unit.

The number of credits established in responseto the depositing of coins in larger denominations is determined by a credit computer or credit value assigning means 72 operated by a master, rotary output shaft 74, FIG. 6, of a speed reducing transmission 76 energized by a single electricmotor 78, FIGS. 2, 3 and 8.

The credit computing means 72'used for this purpose is well adapted for economical manufacture and comprises a flat circuit board 80, one side of which supports a plurality of credit impulse contacts or patches disposed in a. credit assigning pattern, to be more specifically described presently. The credit impulse contacts are designated generally in FIG. 16 by the number f82.

The credit assigning contacts 82 are arranged, as will presently appear, to coact with a plurality of; radially the momentary Incremental displacement ofthe spaced scanning or wiper contacts 84, 86, S8-and 90 mounted 9 1 t ansmi s on. u put h t 4 y aresil:

ient conductor disk 92, FIGS. 6 and 7, which continuously urges the supported contacts against the contact board 80 for rotation with the shaft 74. The four contacts 84, 86, 88 and (only two of which are shown in FIGS. 6 and 7) are circumferentially spaced from each other around the shaft 74. However, for simplicity in illustration and description, the four scanning contacts are, shown in circumferential alinement with each other in FIG. 16. The circumferential positions of the coating contacts 82 relative to the positions of the scanning contacts 84, 86, 88 and 90 as shown in FIG. 16 correctly depict the positional relationships of these coacting contacts to each other and the physical structure of the machine.

The radial spacing of the wiper contacts 84, 86, 88, and 90 from each other is depicted in FIG. 16. The outermost contact 84 is moved through a circular path in the course of which the contact moves across an annular series of discrete circuit board contacts or patches which include, as shown in FIG. 16, a motor starting patch 94, a select patch 96, and a series of credit pulsing contacts 98 which are at least equal in number to the maximum number of credit units to be given for the largest denomination coin which the machine will receive.

The wiper contact 86 immediately inward of the outermost contact 84, sweeps through a path which carries the contact over two grounding contacts 100, 102 spaced from each other and connected .to groundthroughthe.

The grounding contact patches 100, 102, 104 and 106' are circumferentially dimensioned'and positioned, as will presently appear, to award a predetermined minimum number of playing credits for 10, 25 and 50 coins deposited in. the machine.

Provision is made for selectively increasing the number of credits awarded for the deposit of coins inithe denominations larger than 5. For this purpose, auxiliary grounding contacts 108, 110 and 112 are provided in the paths of the respective wiper contacts 86, 88 and 90 and-wired to a terminal board 114. Connections are made from the terminal board114 to the grounding patch sides of the switches 36, 38 and 40, as shown in FIG. 16. The number of the auxiliary contacts 108, 110 and 112 which are grounded upon closing of the respective switches 36, 38 and 40 is determined by the use of suitable jumpers on the terminal board 114.

The transmission output shaft 74 has a starting positign which it normally assumes when less than 10 credit is established in the machine. The positions occupied by the credit computing wiper contacts 84, 8 6, 88 and 90 when the shaft '74 is in its normal position are illustrated in solid lines in FIG. 16. Thus, as shown, location of the shaft 74 in its starting position engages the Wiper contact 84 with the motor starting patch'94.

As will be explained presently indetail, the machine responds to the establishment of two or more units of credit to shift the shaft 74 in the counterclockwise direction with reference to FIG. 16 through an acute angle which swings the wiper contacts 84, 86, 88 and 90r which is actuated subsequent to movement oftheshait7i,

to its select position. While the shaft 74 occupies its starting position, depression of the letter buttons 26 and number buttons 28 is of no consequence. Any button depressed immediately returns to its'normal position as soon as it is released from manual pressure.

Upon depression of a letter button 26 and a number button 28 after the shaft 74 has been turned to its select position, the motor 78 is energized to rotate the shaft 74 through the remainder of a single revolution, to bring the shaft back to its starting position, as will presently appear. This movement of the shaft '74 performs a number of functions, a major one of which is the production of a sequence of record selecting, electrical pulses corresponding to the selection made by the depressed letter and number buttons.

Thus, the shaft 74 operates selector pulse generating means 120 which is similar in its physical construction to the previously mentioned credit value computing means 72. Thus, as shown in FIGS. 6 and 7, the selector pulse generating means 120 comprises a fixed contact board 122 mounted in opposed, spaced relation to the previously mentioned contact board 80. The contact board 122 carries a pattern of fixed contact patches illustrated in FIG. 16 and designated generally in this figure by the number 124. The contacts 124 are opposed by four radially and circumferentially spaced sweep or wiper contacts 126, 128, 130 and 132 supported on the shaft 74 by a resilient conductor 134 which urges the wiper contacts against the board 122 for rotation with the shaft 74. Only two of the Wiper contacts 126, 128 are shown in FIGS. 6 and 7. All four contacts appear in FIG. 16 in which the contacts are illustrated in circumferential alinement for simplicity of description.

The relative positions occupied by the contacts 126,

128, 130 and 132 when the shaft 74 is in its starting position are depicted in solid lines in FIG. 16. Thus, as shown, this position of the shaft engages the radially outermost wiper contact 126 with a shaft advancing patch 1.36. Rotation of the shaft 74 to its select position moves the wiper contacts 126, 128, 131i and 132 to the positions illustrated in phantom in FIG. 16. This brings the contact 126 into engagement with a credit sufficiency patch 138.

Rotation of the shaft 74 from its select position on through to its starting position carries the contact 126 over an annular series of discrete selector pulse contacts or patches 140.

The contact 12$ engages a second credit sufficiency contact 142 only when the shaft 74 is in its select posi tion. The next contact 130 coacts with two motor energizing contacts 144, 146, while the innermost contact 130 continuously engages a circular grounding patch 1.48.

In addition to producing electric selector pulses corresponding to the desired record selection, continued rotation of the shaft 74 from its select position back to its starting position automatically cancels credit for the selection made.

It will be recalled that credit is established in the machine by energization of the crediting solenoid 70 which works through the escapement pawl 64 to effect rotation of the accumulator Wheel 56 in a crediting direction by the spring 53. Credits are cancelled by displacing the accumulator wheel 56 rotatably in the opposite direction, the design of the pawl 64 being such that it does not interfere with forced movement of the wheel 56 in a debiting direction.

As shown in FIGS. 6, 7 and 8, a radial arm 150 fixed to the shaft 74 carries an axially extending credit cancelling button 152 in radially spaced relation to the shaft for coaction with an actuating cam 154 and an abutment 156 on the upper end of the previously mentioned credit cancelling lever 52 which is swingably supported on a pivot stud 160 located a short distance below the cam The lower end of the lever 52 carries a support pin '6 162 in a horizontal slot 164 in a horizontal connecting link 166.

The right end of the link 166, with reference to FIGS. 6, 7 and 8, is connected by a pivot 168 with a credit cancelling sector 170 swingably mounted on the support shaft 172 for the credit wheel 56. The sector 170 is continously urged in the clockwise or crediting direction of the wheel 56 by a tension spring 174.

A detent dog or pawl 176 pivotably mounted on the sector 170 and urged toward the serrated periphery 68 of the accumulator wheel 56 by a spring 178 is normally held out of engagement with the wheel 56 by a stationary stud 180, FIG. 7, which engages the pawl to swing it to its inoperative position as an incident of movement of the sector 170 to its normal position by the spring 174. Upon rotary movement of the sector 170 in the counterclockwise direction with reference to FIG. 7, the pawl 176 moves away from the stud and swings down into engagement with the wheel periphery 68 to transmit a counterclockwise credit cancelling movement of the sector to the accumulator wheel 56.

The relative positions of the parts are such that rotation of the shaft 74 from its select position back to its starting position engages the button 152 with the lever cam 154 as shown in FIG. 7. Movement of the button 152 in its circular path forces the cam 154 to the left with reference to FIG. 7, causing pivoting of the lever 52 which moves its lower end to the right.

The lower end of the lever 52 is connected by a tension spring 182 to the link 166 to move the link to the right. thus effecting counterclockwise movement of the sector 170, which causes the pawl 176 to engage and move the accumulator wheel 56 in its debiting direction. The kinematics of the linkage is such that the button 152 acting on the cam 154 and abutment 156 displaces the sector 170 through an angle which rotates the wheel 56 through three credit units of movement in a debiting direction. Before reaching its starting position, the button 152 moves off the lever abutment 165, allowing the sector 170 to be returned to its initial position by the spring 174.

The shaft 74 operates the described linkage to cancel three units of credit for each complete revolution of the shaft.

As previously intimated, the control provided by the invention and incorporated into the wall box 12 is capable of selecting records from different categories, which are priced differently for playing, and charging players for the records selected in accordance with the playing price of the selected records. Thus, some records such as extended play records or stereophonic records may have a playing price of three unitsof credit or 15. Standard records may be played for two units of credit or 10. Yet, the control operates as described to cancel three units of credit as an incident to selecting of either a 10 or a 15 record. However, upon selection of al0 record a price compensating unit of credit is added to the accumulator wheel 56 by an automatic energization of the crediting solenoid 70, upon operation of the shaft 74, as will be described presently.

Temporary swinging of the credit cancelling lever 52 away from its normal position as an incident to rotation of the shaft 74 also serves to swing the coin support bar 50 into an inoperative position to release the supported coin from the crediting zone 32 to drop into the cash box, as previously described.

This same control shaft 74 is used to control the reception of coins into the crediting zone 32 in a manner which allows coins to move into the crediting zone only when less than 10 credit is established in the machine.

As previously stated, the establishment of at least 10 credit in the machine energizes the motor 78 to shift the shaft 74 over to its select position. Moreover, as will presently appear, if at least 10 credit remains in the credit wheel 56 after operation of the lever 52 to cancel credit, rotary movement of the shaft 74 will continue on past to move into a relief 206 on the lug 92,

the normal starting position of the shaft, to automatically locate the shaft in its select position in readiness for the making of another selection. i 7

As mentioned, the slug rejector 30 itself is of a conventional construction. A coin control lever 190, FIGS. 6, 7, 10, ll 12 and 13, projects from the slug rejector 30 and coacts with the r'ejector in a conventional manner well understood in the art, to control movement of coins downwardly into the crediting zone 32.

When located in its normal position, illustrated in FIGS. and 11, the lever 1% serves to block movement of coins into the crediting zone 32 and diverts the deposited coins to the return chute. Depression of the lever 199 from its normal position activates the slug rejector 30 to direct coins into the crediting zone 32, as described.

The coin reception control lever 190 is controlled automatically in accordance with the rotary position of the shaft 74 by means of a lug 192 fixed to the arm 156 on the shaft 74 and projecting from the arm 150 in a direction opposite from the previously mentioned button 152 and in a position radially spaced from the shaft 74. The orientation of the lug 192 with respect to the shaft 74 is such that the rotary movement of the shaft 74 toward its starting position, as indicated by the arrow 194 in FIG. 11, carries the lug 192 into engagement with a cam surface 196 on the free end of the lever 190. As the shaft 74 comes to rest in its starting position, the lug 192 comes to rest adjacent a high point of the lever cam surface 196, as shown in FIG. 12, holding the lever in its depressed position to direct deposited coins into the crediting zone. Rotary movement of the shaft 74 from its starting position to its select" position moves the lug 192 over a ledge 198 at the end of the cam surface 196 to allow the cam defining portion of the lever 96 as shown in FIG. 13, to immediately block the reception of additional coins into the crediting zone.

The rotary shaft 74 also operates, as previously mentioned, to effect an automatic control of the setting of the letter and number selector buttons 26 and 28 which is properly synchronized With the establishment of credit in the machine and operation of the control to effect selection of a record.

Thus, as shown in FIGS. 3 to 5, the shaft 74 supports and rotates a button latch control cam 202 which coacts with a pointed cam follower 294 formed on one end of a button control lever 206 medially pivoted on a support 'stud 208. The lower end of the latch control lever 206 carries a roller 210, FIGS. 2, 3 and which engages a vertical transverse element 212 on a button latch controlled bail 214.

The bail 214 straddles a support frame 216 for the selector buttons, as shown in FIG. 3, and is swingably supported on the frame 216 by two pivot studs 218. Two

generally parallel arms of the bail 214 extend beyond the the buttons, as will be described presently.

As a prerequisite to the selection of a record for playing, it is necessary to establish at least 10 credit in the controls. Before this minimum credit is established, the

.shaft 74 occupies its normal starting position, as explained.

Location of the shaft 74 in its normal starting position engages a raised arcuate cam surface 230 on the cam 202 with the cam follower 204, as shown in FIG. 4, to swing the lower end of the lever 266 outwardly to a button releasing position. Thus, the lever 206, when held in its button releasing position, operates through the bail 214 and U-shaped member 222 to hold the latch control ele ments 228 in positions which free the selector buttons from the coacting button latching structure 232 carried in the frame 216. Hence, any selector button depressed while the cam follower rests on the cam surface 230 will immediately return to its normal position as soon as it is manually released.

Rotation of the shaft 7 4 from its starting position shown in FIG. 4 to its select position shown in FIG. 5, swings the cam surface 230 out of engagement with the cam follower 204, which moves over a radially projecting car 234 on the cam 202 and drops down onto an arcuate cam surface 236 on the cam 202. This allows the lower end of the lever 266 to swing inwardly and operate through the described linkages to adjust the position of the latch control elements 228 to a degree which activates the conventional button latch structure 232 to latch any one of the letter buttons 26 and any one of the number buttons 28 in depressed positions.

Continued rotation of the shaft 74 beyond its select position as an incident to producing electrical selecting pulses as described moves the cam surface 236 out of engagement with the follower 264 to allow the follower to move radially inward into engagement with an innermost 'arcuate cam surface 238, as shown in FIG. 3. The lower end of the lever 206 moves inwardly to the position shown in solid lines in FIG. 3 and operates through the described linkage to locate the latch control elements 228 in positions which cause the button latch structure 232 to lock or block the buttons against manual actuation until such time that continued rotation of the shaft 74 brings the cam surface 239 back into engagement with'the follower 264 to release all the depressed selector buttons.

It should be mentioned that While the latch structure- 232 will operate to latch any depressed selector button in depressed position while the cam follower 204 is resting on the *select" cam surface 236, the selector buttons are not locked or blocked" at this time. Thus, before the cam surface 236 moves out of engagement with the follower 204.the depression of a second letter button after a first letter button has been depressed and latched in depressed position will operate to release the first letter button pressed and latch the second letter button in its depressed position; However, after the cam follower 204 is moved onto the cam surface 238 all depressed selector buttons are locked in their depressed positions and can not'be released by depressing other selector buttons.

Control of the machine in accordance with the amount of the established credit is effected through the agency of a control switch assembly 240 operated by the credit accumulator wheel 56. As shown in FIGS. 3, 8 and 9, the control switch assembly 240 comprises a stationary contact board 242, which supports a pattern of contact patches 244, 246, 248, 250 and 252 in positions illustrated in FIG. 16. The contacts of the board 242 are opposed by two pairs of four contacts each carried by two arms 254 a and 256 mounted on the support hub 62 for the credit wheel 56, as shown in FIG. 3, and projecting in opposite directions from each other, as shown in FIG. 8. The contacts carried by each of the arms 254, 256 have flexible supports which urge the contacts continuously into engagement with the contact board 242. Of the four contacts carried by the arm 256, only the radially innermost contact 258 and the radially outermost contact 260 are actively used. These contacts are electrically connected together and coact respectively with the previously mentioned contact patches 246 and 244, as illustrated in FIG. 16.

The radially innermost contact 262 carried by the other arm 254 coacts with the contact patch 248. The radially outermost contact 264 on the arm 254 coacts with the patch 252, and the next adjacent contact 266 on the arm 254 coacts with the contact patch 250. The fourth contact on the arm 254.is not used. The positions of the contacts carried by the arms 254 and 256 relative to the coacting contact patches are determined by the instantaneous rotary position of the accumulator wheel 56 and operate in controlling the machine in a manner to be described presently.

However, it will be observed, with reference to FIG. 16,

that the arms 254 and 256 have a range of rotary movement from their starting positions which is somewhat less than 180 degrees. The inner contact 258 on the arm 256 remains in continuous engagement with the contact patch 246 for all positions of the arm 256. The contact patch 244 is shaped to engage the outermost contact 260 for all positions, of the arm 256 except two, the starting position of the arm and the position assumed by the arm 256 when two units of credit are established by the wheel 56.

The contact 262 of the arm 254 engages the coacting patch 248 for all positions of the arm 254. The outermost contact 264 on the arm 254 engages the S contact patch 252 only when the arm 254 is displaced by one unit of credit from its starting position. The adjacent arm contact 266 engages the coacting control patch 25% when the arm 254 is displaced two or more credit units of movement from its starting position.

MISCELLANEOUS ELECTRICAL COMPONENTS AND OVERALL OPERATION OF CONTROL CIRCUITRY The matter of describing operation of the control circuitry used in the illustrated embodiment of the invention is complicated by the necessity for describing the various functions and automatic features which are performed and coordinated by the control structure. Among the factors which must be taken into account in this regard is the capability of the control to make different charges for the selection of different records while at the same time enabling the player to select only a lower priced record for playing when the control contains only suiiicient credit for covering the playing price of the lower priced records.

For convenience in presentation, the ensuing description will be presented under appropriate subheadings, which are necessarily interrelated with each other.

Indexing of the Master Shaft 74 From Its Starting Position to Its Select Position As previously stated, the phonograph control provided by the invention is adapted to select records from two different categories which are priced differently for playing. Moreover, the instant embodiment of the invention is designed to charge two units of credit for playing the lower priced records and to charge three units of credit for playing the higher priced records.

The player or customer is given one unit of credit for each coin deposited. Multiple units of credit are given for the deposit of coins in larger denominations, as will presently appear.

As previously stated, the machine will operate automatically to index the master shaft 74 from its starting position to its select position when the player has by depositing coins in the control become entitled to at least two units of credit, which is sufficient to cover the playing price of the lowest priced record. The operation of the control circuitry to provide this automatic indexing of the shaft will appear presently.

Having reference to FIG. 16 in greater detail, the con trol cable 14 from the phonograph connects to the wall box 12 through a terminal panel 270, which connects the power lead 16 to a power line 272, the ground lead to a ground line 274 through a service switch 276, and the pulse signal lead 20 to a pulse signal conductor 278.

Each of the coin sensing switches 34, 36, 38 and 40 is connected at one side to the ground conductor 274.

The. depositing of a 5 coin momentarily closes the switch 34 to ground a conductor 284 and effect momentary energization of the crediting solenoid 70, which is connected between the conductor 284 and the power line 272.

This effects a displacement of the credit wheel 56 and the arm 254 by one credit unit from their starting positions to engage the contact 264 with the patch 252 to energize a 51; credit light 236 connected between the patch 252 and the ungrounded side of the transformer 282. The patch 252 is grounded through the contact 264, the contact 262, patch 248, a conductor 238 connecting the patch 248 through a series of interconnected switches 29% to the contact patch 136 in the selector pulse generator 124, the contact 126, contact 132, and contact patch 148, which is continuously connected to the ground conductor 274.

It has been assumed that at the time the 5 coin was initially deposited the control contained a zero balance of credit. The establishing of Sgt credit in the wheel 56 turns on the 5 credit light 286 but does not effect displacement of the shaft 74 away from its starting position.

With regard to the previously mentioned circuit for the 5 credit light 286, it should be noted that the contact patch 1.48 in the selector signal generator 124 has a continuous, circular form and engages the contact 132 for all positions of the shaft 74. The contact patch 136 is engaged by the contact 126 so long as the shaft 74 remains in its starting position.

With one credit established in the wheel 56, the depositing of a 5e coin operates the solenoid '70 in the manner described to index the credit wheel 56 to a position displaced by two credit units from its starting position. This moves the credit wheel controlled contact 264 out of engagement with the contact patch 252 to deenergize the 5- credit light 286 and engages the contact 266 with the contact patch 256. As the shaft 74 is still in its starting position, the conductor 288 and patch 248 are grounded as previously explained.

The ground circuit is continued through the contact 262, the contact 266, and the patch 250 to a conductor 292 leading to one side of the motor 78, the other side of which connects with the power line 272. Thus, the establishing of at least two units of credit in the wheel 56 automatically energizes the motor 78 to drive the shaft 74 from its starting or home position toward its select position.

Movement of the shaft 74 to a position substantially midway between its starting position and its select position disengages the contact 126 from the patch 136 in the pulse generator 124 to break the ground circuit through which the motor '78 is initially energized. However, energization of the motor 78 is continued through another circuit until it reaches its select position.

By the time the contact 126 separates from the patch 136, the contact 130 engages and grounds the short motor energization contact 146, which is connected to a full cycle relay 296, the side of which connects with the power line 272. Energization of the relay 296 closes relay switch 296-1 to connect the ground line 274 to the motor 78 to continue energization of the motor.

As the shaft 74 reaches its selecfposition, the contact 130 moves ofi the patch 146 to drop out the relay 2% and deenergize the motor 78 leaving the shaft 74 in its select position.

It should be noted at this point that in the event two or more credit units remain in the wheel 56 upon return of the shaft 74 to .its starting position at the end of a record selecting and credit cancelling cycle, the contact 266 is in engagement with the patch 250 and the controls operate automatically to move the shaft 74 on to its select position in the same manner as when two units of credit are established by depositing 5 coins into the machine in the manner described.

When the shaft 74is inits starting position the deposit of a coinin any denomination larger than operates automatically to index the-shaft to its select position Thus, with reference to FIG. 16, location of the shaft 74 in its starting position engages the contact 84 with the motor contact starting patch 94 and engages the contacts 86, 88 and 90 with the respective contact patches 102, 104 and 106, which are connected respectively to the and 50 switches 36, 38 and 40. The contact patch 94 is connected directly to the motor energization conductor 292.

Hence, closure of'any one of the coin sensing switches 36, 38- and connects the motor energizing conductor 292 to the grounding conductor 274 to energize the motor 78 and move the shaft 7-4 away from its starting position. The contact 84 moves out of engagement with the patch 94 before the shaft 74 reaches its select position but energization of the motor 78 is continued until the shaft 74 reaches its select position by the coaction of the contact 130 with the patch 146 in the selectorpulse generator 124 in the same manner as previously described.

Operation of Circuitry to Select Records When Machine Has a Credit Balance or Has Received a Coin Large Enough to Cover the Playing Price of the Highest Priced Record As previously described, a credit balance of two or more credits in the accumulator wheel 56 or the deposit of a coin in a denomination larger than Sgt operates automatically to effect displacement of the shaft 74 to its select position.

' Since three credit units are charged for playing the higher priced records, it is assumed under this subheading that the'shaft 74 is displaced to its select position either in response to the existence of a credit balance of three or more credits in the accumulator wheel 56-, or in response to the deposit of 3. 25 or a coin in the machine.

Starting first with the'assumption that the accumulator wheel 56 contains a credit balance of at least three units of credit, which have been established either by the deposit of '5.coins or as a credit balance remaining after the previous operating cycle of the machine, it will be recalled that a credit balance of three or more credit units in the wheel 56 engages the credit wheel controlled contact 260 with the contact patch 244, FIG; 16. The effect of this is to energize a transferrelay 300, FIG. 16, through a circuit including the. power line 274, contact patch-148 in 'the selector pulse generator 124, contact 132, contact one side of the transfer relay 300, the other side of whichis connected to the other power line 272.

. Operation of relay 300 closes relay switch 300-1 to connect the grounded conductor 302 to one side of an any selection light 306, the other side 'of which connects through a normally closed relay switch 296-2With the hot power line 272.- This energizes the light 306 to indicate to the player that he can make any desired record selection from either of the two price categories of records available for playing' Energization of the relay 300, as described, also closes relay switch 300-2 to connect'the grounded conductor 302 with a 15 pricing conductor 308.

It should be pointed out here that each letter button 26 controls the selection of 5 records each of which has two playing sides. All the records controlled by any one letter button have the same playing price.

7 A plurality of normally open pricing switches 310 are mounted'for operation by the respective letter buttons 26 and are individually connected at one side to a common output conductor 312. The input sides of the pricing switches 310 controlled by the letter buttons26, which 12 control the selection of the higher priced records, are con nected by jumpers 314 with the previously mentioned 15 pricing conductor- 308.

A 10 pricing conductor 316 is connected to the contact patch 138 in the selector pulse generator 124 and is grounded through the contact 126, the contact 132, and grounded patch 148 automatically as an incident to movement of the shaft 74 to its select position. Jumpers 318, similar to the previously mentioned jumpers 314, connect the 10 pricingconductor 316 to the letter button switches 310 corresponding to the letter buttons which control the selection of 10 records.

"It should be clear from the description thus far that the presence of three or more credit units in the wheel 56 effects a grounding of both the 15 and 10 pricing conductors 308 and 316.

Hence, a depression of any one of the letter buttons 26 connects the common output conductor 312 of the switches 310 to ground. The conductor 312 is connected through jumpers with the input sides of normally opened switches 320 mounted for operation by the respective number buttons 28. The output sides. of the respective switches 320 are all connected to the motor energizing conductor 292 previously mentioned.

Hence, upon depression of any one of the letter buttons 26 and any one of the number buttons 28, the motor 78 is energized by grounding of the conductor 292 through one of'the switches 320 and one of the switches 310 to either the grounded conductor 308 or the grounded conductor This initial energization of the motor 78 starts a continued rotation of the shaft 74 in the same direction it moved from its starting position to its select position.

It will be recalled that the ground circuit which initially energizes the motor 78 to rotate the shaft 74 beyond its select position has been established through the engagement of the contact 128 with the patch 142 in the pulse generator 124. Rotary movement of the shaft 74 away from its select position disengages the contact 128 from the patch 142 before the contact 126 engages the first pulsing contact 140.

However, energization of the motor 78 is continued by engagement of the contact 130 with the extended motor energizing patch 144 to ground the latter and energize the motor relay 296 connected to the patch 144. The patch 144 is of sufficient extent to remain in engagement with the contact 130 and continue energization of the motor 78 until the shaft 74 reaches its starting position, whereupon the contact 130 is disengaged from the patch 144 to stop the motor. I F-i i Energization of the full cycle relay 296 continues energization of' the transfer relay 300 independently of the previously described circuit which initially energizes the transfer relay. Thus, upon energization of the full cycle relay 296, relay switch 296-2 closes to connect the ground line 274 through a closed relay switch 300-3 to the ground side of the transfer relay 300.

j In the description thus far under this sub-heading, it has been assumed that the control was'conditioned for selecting a record by at least three credits having been established in the credit wheel 56, to engage the contact 260 with the patch 244. It will now be assumed that the shaft 74 is in its starting position and that no credit has been established in the wheel 56. Under these conditions, the control is activated to select a 15 record or a 10 record in response to the depositing of either a 25 or a- 50 coin, either of which covers the playing price of the most expensive record.

. The depositing of either a 25 or a 50 coin effects displacement of the shaft 74 to its select position as previously described, bringing the contact 84 into engagement with the contact patch 96, as shown in phantom in FIG. 16. Closure of the switch 38 by a 25 coin grounds the contact patch 104 and provides a grounded connection through the contact 80, contact 84, and patch 96 to the conductor 304 to energize the transfer relay 300. Similarly, closure of the 50 coin switch 40 grounds the patch 106 to ground the conductor 304 through the contact 90, contact 84 and patch 96 to energize the relay 300. The relay 300 operates in the manner previously described to ground the 15 pricing conductor 308. The pricing conductor 316 is grounded through the patch 138 in the same manner as previously described.

Thus, with both the pricing conductor 308 and the 10 conductor are grounded, the control is ready to select either a 10 or a 15 record in the same manner as when at least three credit units have been established in the wheel 56, as described. Punching of a letter button 26 and a number button 28 operates under these conditions to efiect rotation of the shaft 74 from its select position on back to its starting position, as described.

The selector pulse generator 124 operates during rotation of the shaft 74 from its select position back to its starting position to send out a series of record selecting pulses through the pulse conductor 278 in accordance with a conventional code which enables the connected phonograph 10 to make the desired record selection.

Upon energization of the transfer relay 300, a relay switch 3004 connects the pulse conductor 278 with a conductor 330 connected directly with three of the pulsing contacts 140 in the pulse generating means 134. The three pulse contacts connected directly to the conductor 330 lie between twenty pulse contacts 140 controlled by the respective letter buttons 26 as will presently appear and ten pulse contacts 140 controlled by the respective number buttons 28. The contacts connected directly to the conductor 330 are designated in FIG. 16 by the number 332.

A plurality of normally closed switches 334 are connected in series with each other and mounted to be opened by depression of the respective letter buttons 26. One end of the series of switches 334 is connected to the pulse conductor 330. The sides of the respective switches 334 more remote electrically from the conductor 330 are connected to the respective pulse contacts or patches 140 ahead of the three pulse patches 332 with respect to the approach of the contact 126. The contacts 140 connected to the switches 334 correspond to the respective letter buttons 26.

The number of the contacts 140 connected through the switches 334 with the conductor 330 is determined by which of the letter buttons 26 is depressed. Opening of one of the switches 334 cuts out all of the pulse contacts normally connected through the switch to the conductor 330.

The pulse conductor 330 is also connected to one electrical end of a plurality of normally closed switches 336 connected in series and mounted to be opened individually upon depression of the respective number buttons 28. The sides of the switches 336 remote from the conductor 330 are connected with the respective pulse patches 140 located between the pulse patches 332 and the starting position of the contact 126. Opening of any one of the switches 336 by the depression of its corresponding number button 28 cuts out all the pulse patches 140 normally connected through the switch with the conductor 330.

It will be observed with reference to FIG. 16 that middle contact 332 has a spacing from the trailing one of the contacts 332 which greatly exceeds the normal spacing of the other pulse contacts 140.

Upon movement of the shaft 74 from its select position back to its starting position the contact 126 moves across the successive pulse patches 140, momentarily grounding the pulse conductor 272 each time the contact 126 engages one of the patches 140 which is not disconnected from the conductor 330 by the switches 334 and 336.

Operation To Select a Record After Deposit of Ten Cent Coin or When Machine Contains Two Unit Credit Balance As previously explained, a two credit unit balance may be established in the accumulator wheel either by depositing 5 coins or as a credit balance remaining after a previous operating cycle.

Displacement of the accumulator Wheel 56 by two credit units from its starting position does not connect the accumulator wheel controlled contact 260 with the contact patch 244 to energize the transfer relay 300. Consequently, the relay switch 300-2remains open and the 15 pricing conductor 308 remains ungrounded and ineffective. Hence, upon depression of a number button 28 and a letter button 26 corresponding to a 15 record, the motor energizing conductor 292 is connected in the manner described to the pricing conductor 308, which is in this instance dead. Hence, nothing happens.

However, the 10 pricing conductor 316 is connected to ground through the contact patch 1.38 and contact 126 in the pulse generating means 124. Hence, upon depression of a letter button 26 corresponding to a group of 10 records and a number button 28, the motor energizing conductor 292 is grounded to start rotation of the shaft 74, which is carried through to completion as previously described.

Thus, when the accumulator wheel 56 contains only two units of credit, the control will operate to select any 10 record but makes no response to an attempt to select a 15 record.

The deposit of 2. 10 coin in the machine closes the switch 36 to index the shaft 74 to its select position, as described. This moves the contact 86 out of engagement with both the patches and 102, which are grounded through the switch 36. Hence, the patch 96 is not grounded as in the case when either the 25 switch 38 or the 50 switch 40 is closed. Consequently, the transfer relay 300 is not energized and the 15 pricing conductor 308 remains dead. Hence, the motor 78 does not respond to an attempt to select a 15 record.

However, the 10 pricing conductor 316 is grounded in the manner previously described and the controls operate to go through a record selecting cycle in response to depression of a number button 28 and depression of a letter button 26 to select a 10 record.

Conditioning of the control to select only a 10 record, either by the depositing of a 10 coin or the establishment of only two units of credit in the accumulator wheel 56, is indicated by energization of a 10 selector light 350, FIG. 16, by a circuit extending from the power line 272 through relay switch 2962, normally closed relay switch 3005 and conductor 302 grounded as described upon movement of the shaft 74 to its select position.

Since energization of the transfer relay 300 is required to close the switch 300-4, an auxiliary relay 352 is provided to close relay switch 352-1 and connect the pulse output conductor 330 with the pulse signal conductor 27 8 during selection of any 10 record. The relay 352 is connected between the power line 272 and the 10 pricing conductor 316 and is energized automatically when the shaft 74 is in its select position. Upon rotation of the shaft 74 to select a 10 record, a connection between the pricing conductor 316 to ground is continued through the letter button switch 310 which makes the initial ground connection to the motor energizing conductor 292, grounding of the conductor 292 being continued through the full cycle switch 2964 as described.

It may be noted here that the pricing conductor 316 is also connected to a price compensating contact patch 354 mounted on the contact board of the credit value assigning means 82 for engagement by the contact 86 to effect proper charging of the player for the selection of a 10 record as will be described later in detail.

It should be mentioned here, however, that the 10 pricing conductor 316 and the price compensating con tact patch 354 are disconnected from ground upon movement of the contact 126 out of engagement with the contact patch'138 in the selector pulse means 124 in those instances in which the control operates to select a 15 record.

Operation to Establish Credit F 02" Coins Deposited and to Cancel Credit For Records Selected 50 until released near the end of an operating cycle of the shaft 74.

Thus, any one of the coin sensing switches 36, 38 and {it upon being closed by a coin, remains closed after the shaft 74 has moved to its select position and serves to ground the associated grounding contact patches in the credit value computing means $2. I Movement of the shaft 74 from its select position on around to'its'starting'position carries the outermost contact 84 across the successive credit pulse contacts 98, all of which are individually connected to the credit solenoid ground conductor 284. The crediting solenoid 76 is momentarily grounded to add a credit unit to the wheel 56 each time the'contact 34 engages one of the'pulsing contacts 9s while one of, the contacts 86, 8% and $1) is in engagenient with a grounding patch connected to ground through the closed one of the coin sensing switches 36, 38and 40.

Thus, closing of the 10 switch 36, for example, grounds the patch lltlll, which has sufficient arcuant extent to span a radial angleincluding two adjacent credit pulse contacts 93. Hence; the contact 86'will remain in engagement with the grounded-patch 180- while the contact 84 engages two successive pulsing contacts98 to register two credit units forthe 10 coin deposited. In theevent the auxiliary grounded contact 1&8 in the path of the contact 86 is connected through the terminal board 114'with the contact patch 100, the. contact 86 will ground the contact 84 while it is in engagement with a third one of the pulsing contacts .98 to add an additional credit unit to the wheel 5 6for the deposit of a 10 coin.

Operation of the'computing unit 82 in response to closing of the switch 38 by coin is similar to operation to establish credit for the depositing of a 10 coin except that the grounding patch 104 has an efiective arcuate extent greatly exceeding that of the grounding'patch 1th? and operates through the contact 88 to ground the contact 84 as it traverses a number of the pulsing con tacts 98 equal to the number of credit units to be given the player for depositing a 25 coin. Ordinarily at least 6 credit units are registered for a 25 coin. Additional credit units can be established by connecting the auxiliary patch 116 to the main grounding patch 164 through the terminal board 11 4.

Operation of the computing unit in response to closure of the switch 40 by coin is similar to the described operation to give credit for a 25 coin except that the grounding patch 166 covers a greater radial angle to give more bonus credits for a 50 coin, which credits can be further increased by connecting the auxiliary patches 112 tothe switch 141) as described.

Charging of the player for the individual record selected in accordance with the playing price of the respective records is accomplished by the described structure in an extremely efiicient manner.

In moving from its select position onto its starting position to effect selection of a record, the shaft 74 operates through the previously described'credit cancelling 16 linkage't'o mechanically cancel three units of credit shortly before it reaches'its initial starting position. This, of course, is the playing price of the higher priced or 15 records and serves to properly debit the established credit for the selection of a 15 record.

However the shaft 74 operates in the same maner to cancel three units of credit when a 10 record is selected. Yet, the player is'automatically charged only two units of credit for a 10 record." This is accomplished by operation of the described control structure to automatically enter a single additional credit into the accumulator wheel 56 as an incident to operation of the control to select a 10 record and before the three credit units are cancelled by the shaft '74. This price compensating unit of credit is added only when the control selects a 10 record.

It will be recalled that after the contact 126 leaves the contact patch 138 in the selector pulse generating means 124, the 10 pricing conductor 316 is energized only in those instances in which a letter switch 310 corresponding to a 10 record has been actuated. Continued energization of the pricing conductor 316 during operation of the shaft 74- to select a 10 record grounds the pricing contact patch 354 in the path of the contact 86 in the credit computing means 82. While passing over the pricing patch 354, thecontact S6 grounds the contact 84 while the latter moves over one of the credit pulsing contacts $3 to momentarily energize the crediting solenoid 78 to automatically add the desired price compensating credit unit into the wheel 56.
