To all whom it may concern:

Be it known that T, JOHN L. C. RomsoN, a citizen of the United States, and residing at University, in the county of Albermarle and State of Virginia, have invented certain new and useful Improvements in Automatic TalkingMachines, of which the following is a specification.

My invention relates to the class of disktalking machines or graphophones and pertains primarily to mechanism whereby a plurality of talking machine disks are fed automatically into playing positions. The mechanism is electrically controlled and after the main switch has started the playing of the records, the operator may absent This improved machine will then play record after record, feeding a.

new needle for each record, and after rendering the last record will automatically begin over again and replay -the records con flfffluillly untilthe electric power is switched o Such construction will be found articularly applicable and valuable in music halls, moving picture theaters, dance rooms, theaters, cafes and in the home.

One important feature of said invention consists in the fact that the necessary mechanical functions which take place between the rendition of each record, start their op eration immediately after the last tone of a record just played has been reproduced. lDirectly after a record has been played, these operations begin, whether the said record he a long one, viz. a record on which the needle grooves extend far from the edge, or a short one, viz. a record with a long or short radius on which there are less needle grooves circulating from the edge toward the center.

Another important feature ofthe invention consists in the fact that by means of clock mechanism, the operation of the machine may be begun and automatically stopped at a predetermined time for which the clock was set. Tn the same manner the a machine may also be started at any predetermined time.

Another important feature-of said invention resides in the fact that the swing of the sound arm can be utilized for the changing of the sound box needle, and for the making 7 and breaking of the several electric contacts.

The invention further relates to a new and improved means for automatically feeding a new needle for the playing of each record whereby if there are one or more records in the machine for which soft tone needles are preferred, by a simple operation they may always be automatically fed to the desired record or records.

Regarding the operation of themachine generally, an important feature resides in.

the fact that by means of a vertically movable carrlage, the surface of the record which is in playing position will always be of substantially the same height, that is, for each record which is released from the magazine the rotating table will be lowered the distance of the thickness of the released rec- 'ord and its contact disk, irrespective of the tages of my improvements will fully appear from the following description taken in connection with the accompanying drawings and be explicitly defined inthe appended claims. T wish it understood, however, that this disclosure is illustrative only and that the principle of my" invention may beembodied in constructions other than the one specified herein.

Tn the accompanying drawings forming a part of this specification, similar reference parts are referred to by thesame reference numerals.

The placing of the records in the magazine, turning on the electric switch and raising the sound box :--As shown in Fig. 1 the lunger pin 9 is slightly turned which allows the attached pins 10 to fit in the slot 11 and causes the pin to be pushed against the beam 29 by the tension of the spring 13 which bears on-the )late 12 and 'on the other end against the pins 11 of the of the bearing 17, as shown in Fi s. 1 and 5, the attached mechanism may ielifted 7 thereby making a break in the record drive shaft 44 at the top of the record magazine so that records and their contact disks may be placed therein. The said mechanism which is attached to the bearing 17 and raised with it, consists for the most part of the following: the shaft 18 and its cross bar 19 whichsli de through the shaft 106. The rods 20 which are set in the cross bar 19 by the set screws 21 are also attached to the shaft 18. The disk 22 into which the rods 20 are set by the set screws 23 and which support the weight of the attached mechanism and that of the records on the turn table, except for that which the spring 30 bears, are also attached thereto. "When the cross bar 19 is raised and reaches the bottom of the knock-out bearing 111, it pushes it out of the collar 110 and raises the mechanism attached to the bearing 111. This mechanism consists of the following: shaft 106, the record releasing magnets A and their commutators' 101 and 104 which are attached tothe shaft 106 by the bracket 3 on the swinging arm assembly 141, and the attached rods at the end of each arm which control the record releasing dogs.

The upper end of the shaft 44 is .splined so that when the magazine is closed it injterlocks with the lower end of the shaft 106 and rotates the record magazine and the mechanismconnected to the shaft 106, the

25 upon which rests the record turntable 47 upon bearings 46. The carriage 26 slides by means of the rollers 27 and 28 upon the beam 29 which is attached to the casing at the bottom by means of the bracket 31 and at the top by the bracket 32 and held with the set screw 33. The carriage rests on the coiled spring 30 which is of such a strength that it takes the extra weight of the records that are placed upon the-turntable 47. When the carriage '26 is raised to the required height the plunger pin whlch has been allowed to rest against the beam 29'snaps into the notch 15 thereby holding all of the raised mechanism up until the records andtheir contact disks have beenplaced in the magazine.-

The armature assembly of the magnets A movable in the slot 114 of the armature as-' sembly 118 thereby allowing the swinging arms of the sliding ring 115 to collapse when the arms of the assembl 141 are collapsed, that is, when the records and their contact disks are being placed into the magazine. Fig. 21 shows the armature assembly with its plate 116 and screws 117 in perspective. Fig. 22 shows in plan the construction of the swinging arm assembly 141, the plate 140 screwed to the arms 141 to hold the ring 145 in its slots in which it slides. This assembly is stationary to the shaft 106 and is shown in Fig. 25 in perspective. Fig. 23 shows a section of the pin 147 attached to the'arm 141 by the screw 149 and the metallic spring 150, the pin fitting into its holii 148, This pin holds" the sets bf the swinging arms col:

lapsed while the magazine is bemg loaded and outward when the machine is operating. This samepin arrangement is shown in bottom fragmental plan in Fig. 24.. When the arm assembly 141 is collapsed the armature assembly 118 which is in the construe;

tion just above the assembly 141 collapses simultaneously as the rods 120 prevent any arm of either assembly from folding with out also folding the arm above or below it as the case may be. If it is desired that ten inch records be placed the vertical supports 146 are pushed in onthe assembly 141 and the screws 144 are screwed into the holes P 142. I The rods 120, at 119, slide in aslot in the arms 141 dependent upon the movement of the vertical support 146. Should other sized rerords besides 10 and 12 inch be desired to be put in the magazine it can be done by the makin of a hole for the screw 144 at the required point on the arm 141.

When loading the magazine it is necessary tolift up the lower dog 126 of the upper assembly and keep it up until loaded by the insertion of the pin 280. i

In order that the necessary operations following the reproducing of each record may take place directly after the last tone of the record has been reproduced, whether the record be loner or short (this does not mean whether 10 or 12" but means the variation of the number of needle grooves on a record of either diameter) metal disks of various radii, these radii corresponding to the last few needle grooves of arecord, are placed in the magazine, one over each record to which it corresponds and so when the stylus of the sound box reaches the last few needle grooves of the record, a contact will be made between the metal contact disk 52 and the contact point 51 of the sound arm, thus causing the necessary operations to start immediately after the last tone has been reproduced from, the record. By means of the contact 53 from -the disks 52 to the record drive shaft 44 the current is conveyed through the shafts 44,106 and 18 to the brush .18, and from there through a wire to its respective poiht. I Inthe construction shown, the'pin 280 is released from under the dog 126 after seven records and their corresponding contact disks have been placed in the magazine and thenthe rest of therecords are placed thereon. The number of records that are to be placed in the magazine before. the pin 280 is to be pulled out depends upon the location of the auxiliary record releasing dogs. After the records and their correspond ing contact disks have been .placed in the magazine, the plunger pin 9 1s withdrawn -from the notch 15 in the beam 29 and the sliding cafriage and the attached mechanism is lowered until the disk 22 rests on the contact disk of the top record in the magazlne'.

Theelectric switch 34 is then turned on and'the sound box raised in order that it may close the circuits whichwill cause the sound arm to swing away from the record and the one which will cause the sound box tov be upheld until it automatically releases itself. Both of these operations will be fully described hereinafter. When the main swltch 34 is turned on it starts the electric motor 35 whose pinion 36 meshes with the gear 37 which is attached t6 the shaft 38 by a setscrew 39, bevel pinion-40 also being attached to the shaft 38, by a setscrew 41. The

bevel pinion 40 meshes with the bevel gear 42 which is attached to the upright splined I shaft 44 by a" setscrew 43, the shaft 44 rota'ting the turntable 47 which is keyed in the spllne 45, .and having the bearings 231 and 232, these being preferably set upon the felts 233 to prevent unnecessary vibration. In

" the constructionshown in Fig. 1' a bevel friction gear is used-to send the sound arm away from the records and to bring it back. Thls assembly as shown constructed as follows: Numeral 71 represents a bevel friction pinion whichis attached to the end of the shaft 38 thereby utilizing the record drive power to send off and bring on the J j sound arm. This construction ofthefriction gear is also shown in 35. When.

the magnet D is charged, it attracts the armature lever 67 which is pivoted tothe arm 76 of the bracket 72 as-at 68, and whose fork 69 bears against thebevel friction gear.

70, which issplined tothe shaft 7 3, against the revolving evel friction pinion 71. I This turns-the shaft7 3 which-is supported by the 5 arms 74 and 75 of the bracket 72, and its.

pinion 77 which is attached'to it by the set-- screw 79. meshes with the .gear78 which is attached to the shaft 81 by thesetscrew 80,-

the shaft 81 being set into the socket 82 by the screw 83 thereby turnin the sound arm 66, to the axis of which, t e socket 82 is the sound arm to swing back to the record.

Other forms of. reversible gears may be used but owing to the simplicity, ease of operation and absence of noise, this bevel friction gear (reversible) is employed in the construction shown.

The top of the record drive shaft 44 is splined into its socket in the shaft 106,11ence it not only turns the turntable 47, but'also the record magazine and the record releasing magnets A and the other attached mecll anismx This form of construction enables the records to be released from the record magazine while the turntable rotates thereby saving the time that it takes to sto and start the motor. It also makes it possi le for the motor to always rotate the same weight of records-if it were not for this, the weight to be "rotated would, as the new records were released from the magazine, be increased and the speed of the turntable would hence be reduced and would thereby makeit neces-- sary for the speed of the turntable to be regulated, which besides being trouble would not permit the machine to operate properly and automatically as does this form of-construction shown.

In order that the operator may occasionally regulate the speed of the record a governor represented by the numeral 271 sup speed regulator thus shown is as follows The thumbscrew 265 shown at the platform 8 of Fig. 1 has its extension 266 heldon the end of the bent shaft 267 as is shown in the lan of Fig. 6, the shaft 267 beingsupported y the bracket 269 and having at its end an arm supporting a pad 270' and holdin it against the metal disk 271 ()f the sli i end of the governor assembly 270, the coil spring 268 normally holding the pad against the dlsk 271. When itis desired thatthe turntables speed be increased the thumb screw is screwed down' and to reduce the speed of the turntable, vice versa.

Then automatically follows: l 2. The releasin of the used needle b the swinging out oft e sound arm; As s own in Figs. 7, 8, 9 and 10 the example of the construction of the sound box and its at:

tached mechanism is represented as follows:

menses sound box mechanism so that the lower part may vlbrate independently of the upper part, 183 beingthe tube below the break.

The numeral 18% represents an eccentric which bears in an upward direction upon the needle. thereby tending to make the needle rigid with the block in which the needle lies. The eccentric 18-1 is rigid with the shaft upon which the ratchet wheel 185 and the lever 186 are mounted, and the spring 18'? tends normally to push the ratchet wheel around so that the eccentric 18% will beheld against the needle. 188 represents the notches on the ratchet wheel 185 into which the point of the lever 190 catches thereby holding the eccentric away from the needles position after the used needle has been released and until the new needle is introduced therein, thelever 190 by the spring 191, the block 192 being re-' movable for the insertion of the eccentric 184 in the assembly. The numeral 49 reprcsents the needles.

As the sound arm travels'away from the record the pawl 176 engages the lever 186, as shown in the Figs. 6, 19, 28, 30 and 31, and pushes the eccentric in a downward direction away from the needle, thereby leasing it from the sound box, the lever 190 simultaneously catching the ratchet wheel 185 and locking it until the lever 190 is afterward automatically tripped. The released needle falls into the box 17 8. Fig. 31 shows in perspective an example of pawl which operates its member lever when the sound arm is leaving the record and which simply flops back when the sound arm is moving toward the record, the spring 177 allowing it to flop and spring back as soon as the lever 186 has passed it on its way back to the record.

3. The charging of the magnets which releases a record from'the magazine: As is shown in Figs. 1, 11, 12 and 35, the extending arm 93 moves with the sound arm as it is held rigid with the shaft 81 bythe setscrew 94:. On the end of the arm 93 is thebrush '91 its normal position being against the insulation block 95 but'when the sound arm moves away from the record the brush 91 passes from the insulation block 95 to the metallic contact plate 92 thereby closing the circuit with the record releasing magnets A a through the binding posts'96 and brushes 100 and 103 of the commutator-s 101 and 10 1 respectively,'the brushes being held by the spring arms 99 and 102 respectively? and the arms being connected to, and insulated with .it with its projecting arms, to the end of which are attached, in slots-the rods 120,

the arm 118, it turns the lever 121 to which 7 it is pivoted at 122, 121 being pivoted to 1 16 at 123, as is. better shown in Fig. 3, and to the lever 121, at 125, is pivoted the dog 121 which rests on the lug 130, and is pushed out as the lower dog 126 pivoted to the lever 121, at 127, is drawn in, the dog 124: having at its end the rollers 128 and the dog 126 having at its end the roller 129. In Fig. 3 the positions of these dogs and rollers as they are when the magnets A are charged are shown in dotted lines, also is shown the position of the dog 126 and its roller 129 when the record lifting device is lifting the records back into the magazine. F ig. 2 shows these dogs androllers in plan. The operation of the record lowering device" shown in the construction is as follows: When the record is released from. the magazine, it rests on the roller 131 of the arm 132 which is attached to the shaft 133 by the setscrew 136. The shaft 133 then slides down through the brackets 134. and 135 against the slight tension of the spring 137 and when the record falls to the required point the key 139 which fits into the spline 138 of the shaft 133 causes the arm 132 with the roller 131 to be thrown from under the record and the spring 137 draws the arm and its roller back'to its normal position which is just below the bottom record in the magazine; The arm 132 is hinged at 136' to allow it to turn up when the record lifter is raising the records back into the magazinc, and the spring 136 keeps the roller normally held down. 1 have described the operation of only one of these record lowering "devices but they all operate the same way and at the same time, there being one of them on each of th vertical supports 14:6.

4c. The turning one space of the needle chamber which allows only one needle to be released to the sound box which is at that time directly under the needle magazine: As the sound flllIldS traveling away from the record the roller 169, as is shown best in the construction in Fig. 28, pushes the lever 170 to the position shown, from the dotted line osition. The lever 170 being pivoted to the racket 172, at 171, and normally held in the dotted line position by the spring 173 which has pivoted near its end the point 1741 which is rigid with the lever 17 0 when being pushed projections 152 as it springs back to its norby roller 169 but which flops back over the mal "position, .this position being shown in dotted lines in Fig. 28. The construction of the needle magazine is shown as follows:

' As in Figs. 28 and 29, the numeral 151 .rep-

resents the needle tube chamber, to which are attached the projections 152, placed equal "distances apart, with which the point 174 of the lever 170 engages and turns the chamber one space at a time. The base 151 is mounted on the axle 153 this bearing in the bracket 157 at its bottom and the bracket 154tat its top, the bracket 15-1 being hinged.

to the bracket 155 so that the needle chamber and its tubes: may be easily removed, although the tubes themselves may be removed from the chamber without raising the bracket 154 by simply lifting them out. The perforated disk 156 is attached to the axle 153 and acts as an upper support for the needle tubes. The numeral 158 represents a tube of soft tone needles which in the position shown is directly above the orifice 168 of the glazed plate upon which the bottom needles in the tubes slide prior to, reaching the position in which the bottom needle falls through the orifice 168, while 159 represents a tube of full tone needles, the bottom needle in the tube resting on the glazed plate which is. supported by thebraicket 157. The numeral 160 represents a pin, which under the tension of the spring 164 which-is held by the screw cap 163, fits into one of the depressions of the chamber 151 to hold the chamber in its proper place. The numeral 1 165 represents a Weighted lever, one attached to each needle tube at the pivot 166 and having the end 167 which at that point works 168 but is 'glraduated to a higher level on the opposite 's e from the orifice, so that when the levers 165 are turned to the position of over oralmost over the orifice 168 they are weighted down and their points 167 press against the second needle of the respective tubes thereby holding'all needles up in the tubes except the lowermost one which drops through the orifice. 168 into {the funnel tube 182 of the sound box which is at this time directly under the orifice 168, thenas' the chamber is revolved the weighted lever 165 rides upon the slide 162 and soon the point 167 of the lever 165 is brought slowly without the path-of the needles in the tub thereby allowing the column of needles. to be lowered and the lowermost needle allowed to rest and ride on the glazed plate which is indicated in the numeral 157,

until this tube again comes over the orifice 168 when again only one needle falls through it, and so on. So, as the sound arm travels away from the record, the roller 169 pushes the lever 17 0 and its pawl 17 41 engages one of the projections 152' and turns the chamber .on theblock 181 until on its swing back to the record, the lever 190 on the mechanism of the sound box is tripped by the pawl 179, thus bringing the point of the lever 190 out of engagement with the ratchet wheel and allowing the eccentric 181 to be thrown against the new needle by the spring 187. The spring 180 of the pawl 179 allows it to flop back as the sound arm swings away from the record, operating its corresponding lever only as the sound arm travels toward the record.

Preferably there are as manyneedle tubes in the needle magazine as there are records in therecord magazine. A machine of this construction allows tubes of soft or other tone needles to be placed in the needle magazine for the desired records in the record magazine. In this manner the desired predetern'lined kind of needle will always reproduce the record or records for which they were intended. The many advantages of thisconstruction of needle magazine are evident while a few of the numerous advantages of this construction of needle tube are as follows; The pointed levers 165 allow the column of needles to be gradually lowered and not dropped on theglazed plate beneath them and, too they do not slide on the glazed plate long before they fall through the orifice 168 owing to the graduation of the slide 162,- this prevents their points from being bruised. By this removable tube system and the construction of the tubes shown the tubes may be taken out of the chamber to be refilled, the levers 165 Will form a bottom. to them, making it unnecessary to holda finger at the end of the tube for the purpose of keeping the needles in. The tubes if refilled in this manner may be held at an angle thereby preventing the possible dulling ofthe points. The needle tubes of the machine may of course be made to accommodate any number of needles,

while in. the construction shown each tube which causes the sound arm to be sent .back

' toward the record: As is shown in Fig. 11,

the arm 221 which is attached to the shaft 81 by the sctscrew 222 engages the upright spring metal projection 209 which is attached to the reversible contact 211 as 1s shown in Flg. 12, wh ch is pivoted to the insulation base at 21 0, and pushes the coned to the block at 215 and held against the 3 contact 211 by the spring 214. (The releasing of this contact to its normal position which is on the contact point 216 will be described in its order later.) When the contact 211 'is pushed from its normal position on 216 the circuit to the ma net l) is broken as is shown in Fig. 35 and the bevel friction of the reversible friction gear is thrown into neutral by its springs. This causes the sound arm to stop moving but as soon as 211 contacts with 212 the magnet (l is charged and the bevel friction 70' is caused to mesh with the bevel pinion 71 of the shaft 38 and this sends the sound arm back toward the record. The reversible friction assembly is supported by the bracket 72 and the bevel frictions 70 and 70 are splined to the shaft 73 which is bracketed to the, bracket 72 bv the arms 74-. and 7 The bevel frictions 70 and 70" are preferably made in one piece and are'collared to the fork 69 of the lever 67 which is pivoted to the bracket 76 at 68 and held out of engagement with the bevel pinion 71 by the springs which are behind each of them. i v

6. The releasing of the ratchet which causes the new needle to be graspedzVVhen the'sou-nd arm is moving to the record and while the new needle is in its position in the sound box and sliding on the composition block 181 the lever 190 shown in Figs. 7, 8,

shows 111 perspective a form of adjustable lib fork with its contact breakers for 10 and 12" records, the position of which when set.

Figs. 6 and 19, and the wiring of which is shown in Fig. 35. In Fig. 26 the stem of the device hown is represented by 254:, with its handle and locking pin The numeral 256represents its pivot and binding post and 257 the insulation bctween'it and the surroundings as shown in Fig. 27. The contact breaker for use with 12" inch records is represented by 259, pivoted and insulated to 254 by 262, 258 being the contact point which it normallyrests on and from which it breaks its contact when tripped and springs back as soonas tripped, by the tension of the leaf spring 262. The contact breaker for use with 10 records is represented by 261, pivoted and insulated to 254V by 263, the contact point-260 being the one (in which it normally rests and from which it breaks its contact when tripped, and which is sprung back by thespring 263 after being tripped. Y

lifter the sound arm has traveled back to the edge of the record, its one-way trip 259 which extends out from the sound arm and is bent down in order that it can trip its contact breakers on the fork which is preferably mounted below the path of the arm, trips the contact breaker 25!) (if set for 12" records). When either of these contact breakers 25$) or 261 are tripped, the circuit to the magnet ll (the magnet on the sound arm which holds up the sound box) is broken, which allows the sound box to be released. broken, the contact point 5!) attached to the armature of'thismagnet li lifts olf of its contact point 58, thereby breaking the circuit to the magnet C (the magnet which causes the sound arm to be sent to the rec- Ord) this causing the sound arm to stop moving whereupon the sound box is lowered and the stylus allowed to rest in one of the grooves on the edge of the record. The sound box is lowered by a device. the construction of which is shown in Fig. 29, it being operated as follows: The arm 22?, which is attached to the. rod 63 pushes in th plunger pin 224 against the tension of the sprin thereby turning the ratchet wheel 230 which is held around by a pointed pin 226 under the tension of the spring 227 until the sound box is again lifted up when the arm 228 which is attached to the rod 63 strikes the pointed pin 226 and thereby releases the ratchet wheel 230. A device similar to the construction shown will lower the needle and the sound box'gent] y and prevent the point from chipping the rccordas might have been the case were a lowering device not employed. The device in the construction shown is preferably mounted on a plate 229 and this attached to the sound arm.

Other forms of this device may be used but Immediately after this circuit is The above mentioned contact breakers 259 and 261 need only to be tripped for about a second, .for when the circuit to the magnet B is broken the contacts 60 and 59 are selparated,'as the point 59 is operated by t e armature 54 of the magnet B and this breaks the circuit .to the magnet D (the magnet which causes the sound 'arm to be sent toward the record) and after the contact 59 has been lifted off of the contact 60 the cdntact breakers may be sprung. back to their normal position andthe contacts formed with their members for when the armature 54 is released from the magnet B this magnet cannot be charged again until the record which is then in playing .position, has been reproduced.

8. The releasing to normal position of the pivoted contact which caused the movement of the sound arm to be reversed: As is shown in Figs. 11, 1 and 35, the arm 221 which, when the sound arm reached the extent of its path, pushed the pivoted contact 211 from the contact 216 overon 212 (and. which was held on the contact 212 by the pointed lever 218) has hinged at its end 220 the pawl 219, preferably of spring metal, which pawl, as the sound arm travels back to the' record, trips the tripper 218, which by means of the rod 217, releases the pivoted contact 211 by drawing the point of the lever 213 out of the notch thereon. When pivoted contact 211 is thus released it goes back to its normal position, which is in contact "with the point 216 and is ready to beturned by the arm 221 the next time the ,sound arm travels out ward. As is shown in Fig. 32, the pawl 219 which is hinged to the arm 221 at 220, is of such a construction as to allow it to pass over the tripper 218 of Fig. 11 as the sound arm moves outward from the record.

9. The closing of a circuit directly after the last note has been reproduced from the record, which causes the sound box to be record upon which it is placed. These metal contact disks are represented by the numeral 52, one of them being alsoshown on the record 50 which is in playing position in Fig, 1. Immediately after the last note has been reproduced from this record which i is in playing position, the contact point 51 which is insulated to th'e sound arm 66 as is shown in Figs. 1, 6, 19, 28 and 35, makescontact with the contact disk 52 and completes the circuit to the magnet B through the shafts 44, 106 and 18 and the brush- 18. This magnet B when charged attracts its armature 54 and by means of the rod 63 which through the bracket 55 connects the bellcrank 61 pivoted at 62 with the arm 64 of the sound arm elbow 65, raises the sound box and its stylus from the needle grooves of the record.

\Vhen this magnet B is charged it attracts the armature 54 to whose insulated arm 56 is attached the contact points 57 and 59. The point 57 makes contact with the contact 58 which completes a second circuit to the magnet B and keeps it charged until the circuit is broken by the circuit breaker 259 or 261 of the 10 or 12 recordsetting fork 254 as is shown on the wiring diagram, Fig. 35. The contact point 59 which is also attached to the armature 54 of the magnet B makes contact with the point 60, this completes the circuit, to the magnet D which causes the bevel friction to mesh with the bevel friction pin'ion 71 thereby sending the sound arm away from the record. These contacts 59 and 60 stay in contact with each other until the magnet B is discharged when, of course, they are separated. The circuit however which they form is broken when the pivoted contact 211 is pushed from the contact point 216 by the arm 219 of the shaft 81, and the contacts 57 and 59 are separated from the contact 60 and 58, respectively, a little previous to the time that the pawl 219 of the arm 221 trips the tripper 218 as shown inFig. 11, which allows the pivoted contact 211-to be sprung from the contact 212 to its normal position on the contact point 216, as is shown on the wiring diagram Fig. 35.

The said sound arm 66 as shown in Fig. 1 is supported at its bottom by the shaft 81 which is socketed to it and which at its bottom is journaled into the bearing 82. As shown in Figs. 1 and 1 the sound channel is represented as follows: The numeral 65 is the elbow of the sound arm 66 to which the sound box is attached and 84 is the upright amplifying channel which is a part of the sound arm 66 and whose skeletal cross bar 85 is pivoted to the skeletal crossbar 86 of the elbow 88 of the amplifying horn 89 by the pivot 87, amplifying horn 89 having at its mouth, the adjustable series of slats 90 whereby the volume of sound may either be increased or diminished.

The above operations take place in that sequence until there are no more records in the magazine, when the next operations follow in the manner hereinafter set forth:

1-0. The raising int-o the pat h of a pawl on the sound arm of a contact making and breaking assembly: As the last record is released from the record magazine, the disk 22 is lowered to the point on the shaft 44 that the bottom of the last record was previously, that is, the carriage 26 is lowered until it rests on its bumper which is at the .Fig. 15, pushes down the lever 198 as is earse-a extremity of its passage downward. When the carriage 26 is being lowered to this point its lug 193 which is shown in Figs. 1,6, 13 and 19'pushes down the,lever 194 which is also shown in Fig. 11 pivoted at 195,. and as this lever is pushed down the other end of it pushes the tripping assembly up which raises the graduated lever 198 in the path of the pawl 20.7 whichis pivoted to the sound arm at 208, as is shown in. Figs, 11, 13, 14 and 15, the assembly itself being shown in perspective in Fig." 16. When the record is being released from the maga-. zine, the sound arm is outward from the record so the lever 198 thus raised into the path of the pawl 207 is not to be pushed down'by it until the last record which has just been released, has been played, hence the pawl 207 is pivoted to the sound arm at 208 and is of such construction that it will pass over the lever 19,8 and not push it down as the sound arm. swings over to the last record priorto its reproduction, as is shown in Figs. 14 and '15. When the lever 194 is pushed down by the lug 193 on the carriage 26, it is held in that position by the weighted lever 194 which is pivoted to its bracket 194 which has a'stop on it to keep the weighted lever in its normal position as is shown in Figs;- 11 and 13. This weighted lever 194 looks the lever 194' down until the lever 194 is released by the lower lug 193' of the carriage 26.

11.. (After the last record has been played). The tripping of the contact breaking assembly, which breaks the circuits to the drive motor and to the magnet which causes the sound arm to move from the rec- 0rd: After the last record from the maga zine has been reproduced, the sound arm travels away from the record as usual and the hinged pawl 207 thereon as shown in shown more especially in Fig. 16. When this lever 198 which is pivoted to its base 196 at 199 is pushed down, the contact 201 is raised from its member contact 202, the contact .203 is raised from its member contact 204,- and the contact 205 completes a circuit with its member contact 206 which is preferably hung over the contact 205 and mounted on the base 196. When the contact 201'is raised from its member contact 202, the circuit to the magnet D is temporarily broken, this causing the movement outward of the sound arm to stop when it will be brought to a standstill while the pawl 27 of the sound arm is engaging the lever 198 as shown in Fig. 15, the wiring of this assembly being shown more especially in Fig. 35.

l Vhen the contact 203 is raised from its memher contact 204, the circuit to the record drive motor 35 is temporarily broken, thus causing the rotating support 47 and the recon the rollers on the shaft of the record lifting motor which causes the pinion of this motor to be clutched, which sends the record lifting carriage up: Tn the construction shown of this modified'clutoh assembly in Figs. 33 and 34, the numerals 238 and 239 represent weights on the levers 236 and 237 respectively, which levers are attached by pivots 240 to the shaft of the motor 234 and the ends of which are on the springs 242 normally held- (when motor is not running) out of the graduated slots of the extension 241 of the loosely mounted pinion 235, and which is integral with it, this pinion and its extension turning with the motor when clutched by the ends of the levers 236 and 237. Hence when the shaft of the motor 234 starts revolving, centrifugal force sends the weighted ends of the levers outward, and

this in turn causing the other ends of the levers to be pressed inward into the graduated grooves of the extension 241 of the pinion 235 thereby locking the pinion 235 to the shaft and. rotating it. This clutch is of such a construction that the pinion 235 of the motor234 will always turn when the shaft of the motor turns and further will allow the record lifting carriage 244 to descend to its normal position aft-er having raised the records up into the magazine, without having to rotate the shaft of the motor and its more or, less comparatively heavy armatures, but simply rotate the pinion 235 which is loosely mounted on the shaft of this motor.

As shown in Figs. 1, 6 and 35, the pinion 235 which is clutched b-yv the assembly indicated by its pivot 240 mounted on the shaftof the motor 234, meshes with the gear 235 which is mounted on the shaft 235 the shaft 235 having bearings 245' and also having mounted upon it the pinion 244 which meshes with the rack 244'. which is mounted upon the side of the record lifting carriage 244, thereby lifting the carriage,

it rolling on its-slide 250 which is bracketed the fork 249, which as it is raised upward, straddles theturntable 47, thereby lifting the records thereon by allowing them to rest 249 of the record lifting fork 249. l As the records are being lifted into the magazine they push the roller 131 up on its 248. To the carriage 244 is preferably cast,

hinge 136' which by means of its spring 136 flops back after the records are raised into
