As illustrated in the drawings, FIGURE l, the phonograph 2l) forming the exemplary embodiment of the invention illustrated comprises a toroidal magazine 22 adapted to receive and support one hundred records 24 which provide two hundred playing sides. The records "-24 are supported on edge in the magazine 22 in circumthe record pla-ne of the turntable. A record to be played is moved by rotation of the magazine 22 into alinernent with one or the other of the transfer stations 30, 32, depending upon the side of the record to rbc played. The tone arm 28 always plays the adjacent side of the record on the turntable. Transfer of a record from the station 30 to the turntable 26 brings one side of the record into playin-g relation to the tone arm 28, while movement of the record from the station 32 into assembled relation with the turntable brings the opposite side of the record into playing relation to the tone arm.
Records are moved upwardly and laterally from the respective transfer stations 30, 32 to the turntable 26 by two Scythe shaped transfer arms 34, 36 pivotally mounted in underlying relation to the magazine 22. The respective arms have upwardly projecting free ends which are swung upwardly through the respective transfer stations "to carry records into alinement with the turntable.
The construction of the magazine 22 in relation to the transfer stations 30, 32 is such that the magazine moves records into alinement with only one of the two stations at a time. VThe record -in alinement with one of the two transfer stations is shifted to the turntable by the corresponding one of the arms 34, 36, while the other arm remains in j its normal position. After the record is played, it is lowered back into the magazine by the arm which initially shifted it into playing position.
Rotation of the magazine 22, operation of the arms 34, 36 to transfer records to and from the turntable `26, and 'operation of the turntable 26 and tone arm 2S to play the individual record is effected by conventional operating mechanisms in the phonograph 2G which are substantially identical to mechanisms provided and used for the same purposes in certain well known commercial phonographs which are usually coin controlled. v
For a description of magazine operating-'and record playing mechanisms similar to those used in the phonograph 20, reference may be made to United States Patent 2,796,263. `In View of the well Iknown character of these mechanisms in the commercial field, further description here is unnecessary in order to convey an understanding of the invention. The lower portion of the mechanism used to rotate the magazine 22 and effect playing of the records is illustrated schematically in FIG. l and identified by the reference number 38.V
The phonograph 2b `forming the exemplary Vembodiment of the invention serves to supply selectively a plurality of continuous programs :of background music from corresponding categories of records iu the magazine Thus, the one hundred records inthe magazine 22 are arranged in different categories or groups, each of which is designed to provide a continuousprogram of back?,
ground music. Moreover, as will presently appear, the records in the category corresponding to the program music to be played are successively played in endless succession for an unlimited period of time. The operation of the phonograph will become more apparent from the ensuing description of the'structure involved. g Thus, a shaft il@ extending vertically downward from the center of the magazine 22 is connected for rotation with the magazine and used to position the magazine rotatably in various indexed positions or rotary stations in relation to the record transfer stations Btl, 32. The lower end of the shaft Il@ carries a selector stop arm 42, FIGS. l, 2 and 3, which has a free end projecting radially to one side of the shaft. This arm is mounted on the shaft 40 by means of an alined support dd which provides for limited downward swinging movement of the arm from its normal, generally horizontal position. Conventional components of the record playing mechanism 38 are connected with the arm 42 to swing the arm downwardly momentarily as an incident to theplaying of each individual record. The manner in which this arm is actuated to move downwardly in timed relation to the completion of the playing of each successive record conforms to the conventional mode of operation of the mechanism 3S, and will be well understood by those skilled in the art without further explanation. v
The free end of the arm 452 carries an upwardly projecting stop pin 1% which coacts with a generally flat, annular selector ring 4,8 to effect stepping of the magazine rotatably to successive indexed positions, as will be de.- .scribed. v i f,
It is fitting to .mention here that the hundred records Vin the magazine 22 of the instant magazine are divided into four` categories of twenty-live records. yThe selector ring 43 is designed to coact with the stop idro effect playing an endless succession of one side of a'categcry of twenty-five records followed by playing of thev other side of theV same twenty-five records.
Thus, the ring i8 is shaped to define two series of selector `abutment stops 50 located generally on diametrically opposite sides of the ring, as shown in FTG. 3. Each of the two series S2, 54 of abutments extends circumferentially through an arc of approximately `90 degrees and comprises twentydive circumferentially spaced y abutments corresponding to the twenty-verecords in one category. Except for the rst abutment in each series, the abutments Sil are defined by the sides of circumfersacristieV The program determining means to be describedylo- Cates the selector means i8 in a prognam determining entially spaced apertures 56 formed in the peripheral edge of the selector ringed.
The selector abutments 5l? thus formed on the ring d8 are disposed in interfering relation to the rotary path of the selector stop d5 on the arm d2. Two diametrically opposedk arcuate recesses 53, 6) formed in theperiphery of the ring 48 between the two series 52, 5d of abutments provided .for unobstructedrotary movement of the stop 46 between the two series ofv abutments. 1
The selector ring itt is supported by three guide rollers V62. The axes of the three guide rollers 62 lie on a circle Vconcentric with the shaft 4d, whereby the selector ring 48 ismounted concentrically about the shaft id for con# f centric rotation relative thereto. Thus supported, the selector element 4S is positioned rotatably in any one of four equally spaced program determining positions corresponding to the four categories of records in the magazine 22. This positioning Vof lthe selector element is elfected by program selecting structures to-be described.
' and need not be described here.
lposition in a manner which provides for limited free rotation of the ring through an angle equal to the angular Y spacing between the records 24 in the magazine 2L. Moreover, the ring 48 is biased rotatably in a direction opposite to the directionofindexing movement of the magazine 22, so that it tends to seek arotatably retracted position. Y y
T he conventional record playing mechanism 33 operates tto turn the magazine 22 and the selector stop arm 42 in a clockwise indexing direction, as viewed from above. This rotary indexing movement of the magazine is repeatedly effected at the completion of the playing of each successive record. It causes the selector stop 46 to engage a coactingone of the selector'abutmentgs -50 to rotate the selector ring 4S with the magazine until the selector vring is stoppedv by coacting program structure to be described. This termination of rotary movement of the magazine locates a record 24 in alinement with one of the transfer stations 3l), 32 and triggers operation of the record playing mechanism, as will be described, to effect playing of the record.
As the mechanism 3d cycles toV return the record to themagazine 22 at the completion of a record playing operation, the stop arm `i2 is momentarily swung downwardly by automatic operation of the mechanism 38.
The stnucture and mode of operation of the mechanism 38 which eifects this automatic downward swinging of the stop arm 42 are conventional in the commercial art It is sufcient to note that the mechanism 38 coacts with the arm 42 to Veffect this function and that the larm is pivotally mounted on the support d4 to provide for this movement.
The downward movement of the arm 42 disengages :the stop 46 from the coacting abutment 501, allowing the selector ring It to be retracted rotatably through an angle approximately equal to .the (angular spacing between adjacent records 24 in the magazine 22. The arm 42 immediately returns Ito its normal upper position, causing the stop 46 to move .up into interfering relation to the next adjacent abutment 50. Thus, the stop moves up' or stepped to twenty-tive record playing positions corre-` spending to the twenty-five abutments in the series 52, for example. This brings the twenty-five records-or the corresponding category of records into successive alinement with one of the transfer stations 30', 32 to VeifcctV an automatic playing of one side of the records in succession.
After the stop 46 has cleared the last abutment 50 of the series 52, the rotary indexing movement of the magazine 22 carries it through the arcuate recess 58 to engage the first :abutment 50 of the series 54. The'indexing or stepping action previously described is repeated to move the magazine intoV twenty-live positions correspending to the abutments in the series 54. This brings -the same twenty-live records* of the category being played into alinement with the other one of the record transfer stations 3d, 32 to eifect an automatic playing of the other side of the respective records. In this connection, it `will 'be noted that the stop 46, in moving from the iirst 'abutment of the series 52 into coactinr relation with the firstl abutment of the series '54, is carried through an angle of approximately which is equal tothe angu lar spacing of the two transfer stations 30, 32 about the axis ofthe magazine.
The automatic cycling of the magazine continues to elfect playing of .the successive records in endless succession, the stop 46 continuing from one of the series of abutments 52, 54 to the other successively to effect playing of the respective sides of the records.
In this manner an endless program of background music can be supplied over an indenite period of time from a single category of the records in the magazine 22.
The selector ring 48 is positioned rotatably in any one of four equally spaced progiiarn positions selectively by means of a program selecting assembly 70. This assembly 7 0` is movable between a retracted program selecting position, which leaves the selector ring 48 free to rotate with the stop 46,`v and an extended program de.- terminin-g position which coacts with one of a series of four program stops 72, FIGS. 2, 3, 6 and 7, on the selector ring 48 to locate the ring in a selected program determining position. j
Preferably the program determining assembly 70 comprises a generally horizontal arm 74 supported for swinging movement about a vertical pivot 76, FIGS. 2 and 5 to 8. The pivot 76 is mounted in a bracket 7'8 secured to the frame structure I80 of the machine.
The l underside of the arm 74 carries a pivotal selector ring locating and retracting lever 82 which has a radially outer end deiining a depending ear `84 which forms an intermediate abutment that is engaged by a coacting one of the program stops 72, as shown in FIGS. 6 and 7. A spring 86 connected between the radially outer end of the ylever82 and the arm 74, as shown in FIGS. 2, 5, 8 and l0, urges the lever in a counterclockwise direction as viewed from above to elect an intermittent rotary retraction of the selector ring 48, as will presently appear. When the program selecting assembly 701 is in its program determining lposi-tion, the intermediate abutment 84 is disposed in interfering relation to the path of a coacting program stop 72 which engages the abutment `84 and swings the lever `82 fagainst the spring 86 until the abutment 84 engages an adjustable limit stop` 88 on -the arm 74, lFIGS. 2, 6 and '7. This terminates rotary advancement of the selector ring 48 and acts through the `selector stop 46 and the coacting selector abutment 50 to locate a record in a transfer position, as described.
Upon downward movement 'of the arm 42 to disengage the abutment stop` 46 'from the coacting abutment 50, as described, the spring 86 acts through the intermediate abutment `S4 to retract the selector ring 48 rotatably through a limited angle approximately equal to the angular spacing 'between the adjacent records in the magazine 22. The rotary movement oi? the selector ring 48 in the reverse direction by the spring 86 is limited by engagement of the support bracket 907 for the coacting program stop '72 with a one-way stop dog 92 pivotally mounted on the underside of the swingable arm 74. The dog 92 is supported on a pivot 94 and biased by a spring 96, FIG. 10, in a manner such that the coacting program` stop bracket 90', in moving in a magazine indexing direction, engages the dog which pivots to let thebracket pass. However, as the bracket 90 is moved in a reverse direc- ,tion by the spring 86 an adjustable abutment 98 on the dog 92 engages a coacting abutment 100 to hold the dog against reverse pivotal movement and thereby limit reverse movement of the selector rin-g 48. i
It is noteworthy at this point that the limit stop 88 is formed by an adjustable screw and that each program stop 72 is formed by an adjustable screw. 'Ilhese adjustable stops provide vfor a rotary adjustment of the rotary position in which forward rotation of the ring 48 is'term-inated. The adjustable stop 98 on the `dog I92 provides for adjustment of the rotary position in which retraction of Vthe ring 48 is terminated.
As the intermediate abutment 84 is moved into engagement with the limit stop 88 by the `coacting program stop 72, an adjustable switch actuator i104 carried by the inne-r end of the lever 8,2 operates a reversing switch 106 which controls the mechanism `38 to effect the playing of the record brought into alineinent with 4one of the playing stations 30, 32. The reversing switch 106 4is mounted on top` of the swingable arm 74 and :includes an operating blade 108 which is engaged by the actuator 104 as the lever 82 is swung bythe abutment 84. The structural relationship of the switch 106 to the record playing meehan-ism 38 and its mode of `operation in controlling the mechanism to effect automatic playing of a record are substantially identical to the relationship of the record playing mechanism to similar Ireversing control switches in automatic phonographs in commercial usage.
The swingable arm 74 which carries the program selecting assembly 70 is urged to swing outwardly to its program determining position by a spring 110 connected between an ear 112 on the 74, FIG. 5, and a bracket 114 `on the frame 80. The arm is firmly locked in its eX- tended position by a latch 1116 swingably mounted on the arm 7 4 tor engagement with a locking bracket or ear y118 on the bracket 78, FIGS. 5, 8, 9 and l2. Thus, as shown in FIG. 8, the latch 116 is swingably mounted about a pivot 120 carried by the arm 74 in spaced relation to the pivot 76, and in a position on the arm such that the swing-` ing movement of the arm from its extended position toward its retracted position causes the pivot 120 to move toward the locking ear 118. A ledge 122 on the latch I1;16 normally engages the locking ear l1118, as shown in FIG. 8, to hold the arm in its extended position. A spring 124 connected to the latch 116, as shown in FIG. 5, urges the latch in a counterclockwise direction to engage a shoulder 126 4on the latch with the ear i118 to hold the ledge 122 in coacting relation with the ear l118.
The arm 74 lis swung inwardly to its program selecting position by a solenoid 130, FIG. 5, connected through a link 132 with the latch 116. Energization o-'r' the solenoid swings the latch i116 about the pivot 120, to disengage the latch from the locking ear 1.18 and bring an abutment 1'3'4 on the latch 116 Iinto engagement with the main pivot pin 76, as shown in FIG. 9. After releasing the anm 74 in this manner, the solenoid acts through the latch 1116 to swing the `arm 74 radially inward about the pivot 76 `to move the intermediate abutment 84 and stop 88 out of the path of the program stop '72. As the arm 74 reaches its innermost position a switch actuator i136, FIG. 8, on the arm engages a stationary switch 138 to reduce the current ilo'w through the soleno-id 130 to prevent overheating of the solenoid while the atm `is held in its innermost position.
When the program selecting assembly 70 is swung inwardly in this manner, the selector ring 48 is free to rotate to an unlimited degree. Thus, upon lorward rotation of `the magazine 22 after completion of playing of a record, the stop y46 roperates through a coacting abutment 50 to rotate the selector ring 48 until rotation of the ring 48 is terminated by deenergization of the solenoid -130 to allow the spring 110 to swing the program selecting assembly back into `its program determining position.
Thus, in lorder to discontinue playing of any program and select any other category of records for playing, it is necessary only to energize the solenoid i130* and continue energization of the solenoid until the selector ring 48 is rotated to bring the program stop 72 corresponding to the new record category into approaching relation to the normal position "of the program selector assembly. Then, the solenoid 130 is deenergized, allowing the pnogram selector assembly to return to program determining plosition in which it coacts with the new program stop to effect playing of records yfrom the newly selecte-d category.
Control of the phonograph to select any desired category of records for playing automatically in this manner is elfected rby an extremely simple control circuit which lis illustrated diagrammatically in FIG., 13. Thus, as shown, a program selector switch 140i operated by a control knob 142 has four output terminals 144, 146, 148, 150, corresponding to the four categories of records in the magazine 7/2 and connected respectively to four selecspirit and scope of the invention as defined by `pended claims.
tor rin-g position sensing switches 152, ld, 156, The sides of the switches 152 to -158 Iopposite from the switch 14%) are connected through a normally open relay switch 160 to the program selectin-gsolenoid 13h. The other side of the solenoid 134i is grounded and the provgram selecting switchlll is supplied with power through a line le2. The operating solenoid ltd/ll for the switch 160 is energized from lthe line 162 through a normally opten `program selector energizing switch 166 which is controlled by a button 168.
The four position sensing switches 52, 154, 156 and 158 are Vnormally closed. As shown in FIGS. 2 and 5, these switches are mounted vin a vertical tier on the frame 8@ in vertically spaced relation to the periphery of the selector ring d. These `switches are operated selectively by four upstanding switch actuators H2 mounted on the Aselector ring i8 in equally spaced relation toeach other around the circumference of the ring, as shown in FIGS. 2 and 3. Each actuatord'Z carries four trailing tines 174 which are positioned in vertical alinement with the respective switches 152, 154i, 156 and 158. One of the tines 17d of each of the actuators 172 is bowed radially outward, as shown in FIGS. 2 and 3, to effect operation of a corresponding one of the switches l5?. to ll as the actuator i7?- is moved past the position sensing switches. A different tine `ll7dris bowed outwardly on each of 4the actuators l'Z so that the actuators 172, servel to open the respective position sensing switches as the actuators move past the switches.
To select a desired musical program, the operator turns the knob 142 to connect the power line 162 toone of the terminals 1li-i, ldd, MS and l5@ corresponding to the category of records to be played. He then pushes the button 168 to energize the solenoid ieri and close the switch isti to energizethe solenoid 1.3i? to move the program selecting assembly 7i) to its selecting position.
This is subsequently followed by rotation of the selecetor ring e8 in the manner described. It will be apr preciated that the solenoid 13@ is energized through one of the position sensing switches 152, 154, 156 and ll58 corresponding to the desired program. When the selector ring e8 approaches the correct position for playing the kselected program, the position sensing switch through p which the solenoidnldis energized is opened by a corresponding one of the switch actuators i172. This immediately deene'rgizes the solenoid 130 allowing the program selector assembly "76 to return to its program determining uposition to eifect automatic playing of the selected category of records in the manner described.
It fwill be observed, with reference to FlG. 13 that the solenoid switch 166 serves as a holding switch `for continuing energization of the switch solenoid 164 after the start switch liohas opened and until the position sensing switch corresponding to the desired program has opened.
It is also noteworthy, with reference to FIG. 13, that the switch lo@ is connected to the retracting solenoid 136 throughany resistor 123i)` and the previously mentioned normally closed-switch 13S, which are connected in parallel with each other. -t will be recalled that the switch 138 is opened upon swinging of the program selector assembly 7tl to its retracted position. This opening of the4 switch 13h puts the resistor 186 in series with the retractor solenoid 13@ to reduce the current iiow through the solenoid, as described. l
