Iii iny previous @pplicaiion, erial No. 325,766, filed' September 23, 1919, 1 have described and el-,iimed means - @vhereby, upon the complet-ion of a record, the tone arm is 10 returned to starting position and a new record is atitomatically shifted in to take the place of the@ 6ne w@ich has just been played -%vhile tlie ton,6-arm is being returned, sd that the sceond record is played. This action is, 15 repeated until a numb6r of records which %re placed in a iiiagazine have been plaved. e "be Ai the sam @ time that the tone arm is in returned, the spring inotor of the ma. el line is i@ewound so that any iniimber of rec-. 20 ords'within the caipacity of the migazine ii-ic@t wliieh I have described in said application, however, the . individual records of the grotip or stack which are placed, iinl the 25 magazine to be successively played must be all of the same diaineter, although the' diam@ter of the group as a whole may be N,aried. In carrying out'my prese tit invention I so. provide r@eans wliereby the records of the p,rotip which are put fn ih6 magazine may be of different sizes. At present thei-e are 'iwo standard diimet6rs or sizes of reco@,ds. nainel@, the 10 inch and the 12 inch records. 35 By my arrangement the op,-.rator niay@ plaee a nui-@- ber of records of. both. sizes'i@ the. f iiiagazme an(I place one of the records o eitlier size in playing position.

Referring first to Fig. 1, it will' lj,6. seen that disclosed in my app-lication'above referred to. A sprihg motor for the phono75 grtiph is representeu, at 10 as driving the rotatable table 11 through worm gearing 12 in the usual manner. The electric motor @for winding the spring motor is shown at 13, the winding being done through worm .14 so on the motor shaft and -worm wheel 15 on the spring @rbor 1,6. The contacts for controlling the m'otor circuit are re@re@ented at 17- and 18 respectively, contact '17 being di,iven by the spring motor through. worm 19, gears 19', 20, 21 and 22 aiid sleeve 23,, while contact 18 is driven by the electrie-'MOt6r from worm 24 secured to arbor 16 and worm Wheel 25 secured to shaft 26 which P"lFses throtigh the sleeve23. These two con-- -90 tacts 17 and 18 botli have the samo gear re-, lation with their resp e drivin 9 MeM7 bers, i. c., the gear rel between contiict d 17 and the. drum of the spring m'otor -on - which worm 19 is mounted is the same as the ion betw'e'n contact 18 and the ar-

l,e23,559' olution as contact 17 and in the same direc- witli sector 39 in a manner hereinafter detion. Contact 17 is a metallic disk having a scribed. brush 27 engaging its edge and provided In order to lift the iieedle when the iiiowith an e@centric rib 28 of insulating mate- tor is energized and before the turninrial, enel ' g an insililating section 29 of iiiovement of the tone. arm,is beglin, I pro- 7( osm the disk. The contact 18 comprises a siiiii- vide the following arrangement: lar metallic disk- liaving a brush 30 epgagDi-iN7en by the arbor 16 is a disk 42 pi-o' its edge and a spring finger 31 en(va-ing i-ded -%vitli two pivoted I)awls 43 back of ing zn zn the disk of the contact 17. This spring fin10 ger is arrang@d to be deflected by the 1-ib 28 .:so as to snap from the insulating sectioii 20 to the metallic surface and vice versa. This form of contacting device is fully-described in'my Patent No. 1,180,743 and other pat15 ents and, consequentl needs no more detailed description. T@e result of all this is that if there were no other control for the motor 13 than the sliding contticts 17,and 18, when the 1- notor circuit was closed -by the 2o spring finger 31 snapping over on to the inetallic portion of the disk which it eii(yages, the spring woiild be wound up. by jutst the amount which it liad run down. If, lio,%@,ever, the motor circuit should be opened at 25 another point when the contact is made, the electric motor will not, of course, be ener'gized but the contacts ivill continue . in sliding engagement until the circuit is coiiipleted at the other point. In my pi-esent. arranggso ment the motor circuit is contrcilled, by contacts 32 associated with the lever 32' for operating the brake lever 33. The circuit is only closed at the contacts 32 wheu tlle lever 32' is moved inward which applies the 35 brake to stop the machine, so that if th6 g motor had run down fir enougli to sfrie" c os the contacts 17, 18, when the lever 32' is operated to stop the machine, the motor 13 wi.1l.be energizea and,-%vind the spring to its 4o orioinal tension at -wliieh point the n-iotor eircuit will be opened at the coptacts 17, 18. This rewinding arran(rement is covered by, my previous Patent; N@. - 1,440,634. In otlier words, referring to Fi(r. 3 ivlien the ii-la45 chine is stopped the m(@tor Al will be energized from the pltis @zide (;f tlle Iiiie, through the motor @nd slidincontacts 17 S'32 to the nii and 18. and contact' niis side of the Iiiae.

Eacli of these pawls is'so i.-Iounted that wlien it reaches a 75 substantially vei-tical position above the center of the dislc it will drop ovei- away frojii its di-iving I)in if there is notliin- to prevent it. If, liowen?er, the pivoted lever 45 sliould be in the position sliowii in the so draiiing it ivill be enuaored'by 'Llie pawl and turned on its pivot.

If, however, a 12 inch record is put oii the machine and the needle placed in the startiiig position thereof, the position of the toiie ai-m will be sucli that 10 the lug 79 wiJI eiigage the operatiiig iiieinber 81 of the switch R and move it agaiiist th@ spi-ing 80 so that the switcli blades will take the position shown iii fpll lin6s. Iii this position, if the machine is now qtarted, 15 a latch 82 connected by a link 83 with an extension 84 of the bralie lever, will latelt the switeli when the macliine is started I)y the releasin(r of the brake, as will be clearly uiidei@stood from Fig. 3. IVIlen the iiiacliiiie 20 is stopped, however, the Idtch 82 will I)e operated to release the switeli R ind allow it to return to the dotted line position. A stop pin 79' (Ficr. 5) pi-events the accidental closin- of swit7ch L when the machine 25 is stopped w-hich miglit happen if the. tone arm sliould be moved in toward the ceiiter of the record.

In Fig. 4 one of the switch members Qf ,')O limit switch L is shown in detail as -being a snap switch composed bf a S'Witch blade 85.pi oted at 85" and connected with the actuy t L allows the switch blade to move with a snap action in response to the spring tension. '17he two latches are connected by spring 91' as shown. This is a common form of snap switch and requires no further description. 70 In-Figs. 7 to 17 I have sliown an arrangeiiient for automatically changing records. This -,trrangement is stibstantially the saiiie -,is that desci-ibed in my applicatioii first above referred to. It will be observe(I that 75 a. stael- of records is placed at one side of tiie phoiiograpli table from wliicli the records ai-c atitoiiiatically fed to the plionograpli table and tllen automatically transferred to the otlier side of the table. Wliile the tone arm 80 is being returned, witli the needle lifted, to its iiiitiil position, the r'ccord is shifted to the ri-ht aiid another record is mo-@ed froill the lat onto the table to t,,tke its, place. Wlien the iieedle drops, tllerefore, a nenv 85 record sliall have taken the place of the one whichhaSLjustbeenplayed. Tothisend,all the records of -.t certain diameter should liave the tliread begin substantially the same distance from the edge of the record. In- 90 stead of tliis, a -piral thread of steep pitcli sucli as is; eniployed at the iriiddle of the record in Fig. 1 migbt be employed wllieli would stai-t @t the proper distance from the edge and end at tli(,- beginnin(, of the regular 95 record thread. I prefer, however, to liave the i-egular thread begin at the proper distance from the edge of the record since this can easily 100 be done in making @, record. Referring now to Figs. 7 and 8, it will be seen that a stack of records is placed in a magazine at L 85. - This magazine will liold records of any standard size which are eenh 86. L In my 105 tered in t'he'magazine by a pi previous application, as above stated, the records put into this magazinq, at one time must all be of the same size, whereas, by my pres'ent invention records of different sizes may be put into the magazine. The 110 record8: a're'autoinatically fed to the level Qf, the table, i. - e., when a record is withdrawn another. takes its place', in a manner hereinafter, described. At 87 is- another magazline for receividg records after they 115 have been played. In otber words, the stack of records is transferred-from 85 to 87. For ating membet 86' aleo pivoted a 85" by a @li-ecomplishing this purpose I enaploy, in the doubleactuatingspi-ing87'.

arii@ 88 to -oo throucrh its cbmplete eyel . e. I)uri@g t-he ;laying of the . record the arm is !li its central position as shown in the drawin , tlie,pin 89 orf its end acting as a cen9 terin(, pin'instead of the ustiql pin on the table. Wheii the shiftin(r lexer 88 is started, M. it first moves the arm and witli it the record 5 which has been played, to the right.as far as the ma@azi'l" 87. The arm then starts le 10 to the left aving the record behind in the magazine. The arm now moves over to the center of the reeords in the magaziiie $.). and t-lie pin 89 drops into the icenter liole iii the to@ reheoi-d. The, arm now moves back I r) to t,,e ,g t, cartying witli it the top record, the otlier records below it bein(r lield I)v the Ily stops at the table. All this - ai-m is being re'20 and the spring motor is bei@g wotind. e, arr@n(vement of the pin 89 in the end of e arm is shoivii in Fios. 9 and 10. The pin is hinged at 189, so that it will glide over the record 25 when the arm is moved to'the left, but when the arm is'moved to the right it assumes a vertical p6sition. This pin inay liave a surface which bears on the record of some ma.terial which will not scrateli the recol,d, al30 though this may not bo neces@ry since the pi,essure of the pin on the record %vill be very light. In o-rder to bring about the sequence of operations of the arrn 88 above described, 35 I employ a: mutilated annular -ear 91" whi@h is. driven sloivly by the motor 90. The reduction . gearing betiveen the motor and this annular@ear is such.that tlie motor in making its redetermined number of 40 revolutions turns the annular -ear throu(yli one complete turn. The pin;@on 91, which drives the arm 88, is eiigao,,ed on one side by the teeih of the annular gear at 92 to -turn the arni in one direction (to the right) and 45 on its opposite side by teeth 93 to turn the arm in the o@ther direction (to the left). The ntimber of teeth at 92 ,ire sufficient to carry the arm from the ceiiter over to the mafrazine at the right while the teeth at 93 the center of the records in the magazine 85. The teeth at 94 will then carry the arm from that point back to the playing position tlitisconipleting the cycle. 515 Turning now to the details of the ma-(Y:,,izines the n-iagazine 85 is slic@iin in,Fioii7ies ii to 14. It coiilpt-l , ses a casing 95 in the to]p of t,he cabinet 96 liaving its top flush with the top of the phonogr,,tph table at 97. 60 Witliin this casing is a platforlil 98 upon which the records io be played are staclied. The centerin(y pin 86 passes tlirotigh this platf6rm, and also throtigb the center holes ;n the -:ti'ceessive records'. This pin is ver65 ti'callv movable a sligbt distance beeause i@ should be high enough to center the last record when the magazine is filled but must be out of t-be way when the top record is drawn ofF. A sliding frame colasistint of three rods 99 100 101, iiiouiited on a ase To io2, is airanged to be moved upward from its on . lowerniost positi shown in Fig. 11 to itg uppermo-.t position shown in Fig. 12 where it is h6ld b3- the spring pressed balls 103. Secured to tli6 pl@,tform.98 is a U- 75 sh.aped iiiember 104 wllic passes freely tlirough the bas6 102. When the frame iq i-aised, tliei-efoi-e, the base en(rages @tlie platform and lifts it to the posiiion shown in Fig. 12. Between the bottom of tlie. U- 50 sh,,ipe d piece 104 and the bottoiii of the casing is a spring 105 wliich forces the stack of recoi,ds upward when one has been remove d. , Hinged to the top of rod 09 is a coN7 ei- plate 106 whicli may be swung to the 85 positio n shown in dotted lines in Fig. 14. 'this cover is held'down by @ rod 107 having a loop 108 in its middle pdrtion and having its en.ds bent into the, form of cranks 109 adapt ed to engage with hooks 110 on. the 90 tops of rodg 100 and 101. It will be obvious tlat by turning the rod 107 from the. position shown in Fiol-s. 11 and 13 until the loop I 08 is vertical , as shown in Fig. 14, the crank ed ends will pass from under the hoo . ks 95 and assun-ic a horizont@l positi6,n acrainst the cover. In this position the cranks will clear the hooks when the cover is turned on its hinge. Secured to the under, side of the base 102 is a bracket 111 which supports the 100 pin 86 through a spring 112, the rod beino, I)rovi ded, with a collar 113 u oia ivhich the p sprilig bears. When the frame is up as. shown in Figs. 12 and 14 the pin extendi upN, @ard to the' cover plite 106, but when 105 the frame is piished down, as shown in Fill, a pivoted lever 114 on the under side the base 102 en(rages a @tationary Iiig 115 on the cas ng f@reinly the inner end of the lever, wliielinormarly engages the collar 110 113, as shown in Fig. 14, doivnward, so as to move the pin downward against the tension of the spring 112. The downward mQN eni6iit of the pin is just about. equal to record may be slid off without beino" interfered with by the pin. The frame is beld down by two hoolcs 116 pivoted to rods 100 and, 101 and engaging projections 117 oil tlie'cagin(r. Tliese hooks have fingei grips 120 tin4 are htun so is to automatically engalre 9 their projections when the fraine is push@d (]own. To lift the fr,,ime the',finger grips on the.fi-ame ire t@ken hold of and by pulling upward the liooks are di-engatred from the 125 projections and the fi-ame may be lifted up and -latched by the balls. To load the magl,zine, tllerefore, the frame is rai@ed to the position showli in Figs. 12 ind 14, and the cover plate is -swung to 130 50 wily carry the arm froit that poidt over to 'the thickness of a re'cord so that, the top 115

i,623,559 the vertical position. The records of botl-i sizes, if desired, are iiow stacked onto the platform the center pin passing througli the holes in the records. As many records a desired, to the capaci@y of the magazine ma-YuEe put in. In Figs. 11 and 12 I liave sh6wn, for purposes of illustration, the @nagazine only partially filled. The cover is now clamped ciown and the frame pushed 10 downward overcoming the locking balls 103. As the fran-le moves downward, the platform, which is spring pressed upward , does i,ot move until@the cover plate reaches the records. From then on, the records and 15 platform also move compressinc, the spring 105. Of course, if the magazine had been filled, the records wotild have moved at once. 1,Vhen the frame reaches the bottom, it is latched as shoivn in Fig. 11, the centering 20 pin 86 beina in the meantime mo-ved down%vard to th@ position shown in dotted lines in Fig. 11 as above described. It will be obvious no%v that if the top record is drawn out, the platform will be moved upward by 25 the s.prino, so that the next record -will be in the place of the one removed. When the last record is rernoved, the contacts 118 -%vill be brideal by cotitact 119 to stop the inaciiine a" here'inafter described. s 30 The maga@ine 87 is shown in Figs. 15 and 16. It consists of a plat@Orn-i 120 sprin@r pressed tipward by a sprin- 121. When tliei-e are iio recoi-ds in the t3 magazine the I)Iatforiii 120 is flusll witli the rotatin- table. 35 AVI)en t recoi-d 'Is moved onto the pratforin it passes tiiider a (-uide 122 pivoted at 123. The eiids of this gtiide are tui-ned upward as slioii,n so as to start the record under the (ruide and the spriiig 121 then yields to force 40 the i@ecoi-d downNNard so that its upper surface is at the level o@ the table or below. Eacli eiid of the -uide is divided into two fingei@s 124 and 125 which rnay yield some-",hat. Fino-ei-s 125 are a little, Iiiglier thaii 4r) fing,.ei-s 124 and are for en(yagina a smaller. record it its edge, -%i,hereas finaers 124 en(,a(,e ft 1 ar(yer record at its ed-e. Wben t tn t, tn tD large i-ecord enters the inagazine, tlierefore, the fingei-s 124 en(yage it :it its edge aiid p@ess 50 it downward, tli@ fin(yers 125 not lengao-ina n zn the i-ecord, but ivlien a smaller record enters, z@ the fin(rers 125 en(-a(,e it and foi@ce it down the fin(,ers 124 not eiiga-in(r it. The ouide 122 is lield in place by a lat@li 126 bavid@'g an 55 operatin- bandle 127. The latch and liandle, as shown, are on a resilient support so that wben the guide is forced downward the lateli 126 will automatically lock it. To remove the records, the li,.indle 127 is pulled 60 to the i,iaht and the o icle 122 lifted. Wlien the ma,,izine is filled i'vitli records to its limit, the contacts 128 are bridcred by a contact 129 to stop the machine as hereinafter described. 05 In Fig. 17 I h,,ive shown a diagram of the circuit connections for the record shifting motor 90. This motor is energized when the reprodueer reaches the end of the record, and the needle lifted. The needle can only be lifted Nvhen the end of a record 70 is reached so as to close sivitch L by lug 67. In order to insure, however, that the slii-."ting motor is not operated until the needle is lifted, I have its circuit controlled bv contacts 190' which are closed wlien the 71, cliitch gears 34 and 39 (Fig. 1) are thrown in mesh. I also provide a push button switch 130 colitrolled by the operator. If this switch is closed the motor 90 will start, but if it I's open the motor 90 will not start 80 and the i,ecord will be i,epeated instead of a new record taking its place. In otlier ivords, by pusliin- the button R (Fig. 8) so as to open switch 130, the record will be i-epeated but by puslilng button A to close 8r) siiiteli 1.30 the record will be autoinatically sliifted. Wlien the inotor starts it inakes its own circuit at coiiimutator 131 -%vliieli sliort circuits tiie other controllincr contacts. This coinmtit,,itor is (rcai-ed to tli'e"' motor so 90 as to make oiie revo'l'tition while the motoi, I's rotatiiig stifficiently to ,ive the arm a complete cycle. Slip i-in(r '1"32 of this coiniiiut,,ttor is pi-oi,icled witli'an I'nstilatin(, seetion 133 so that wlien the bi-usli ruiis on - this 9:3 insulatl'ii,(,r ,:ection the niotor will stop.

The arrang@ement is sucli that the brake 33 normally operates back and forth witliotit bein- affected by l.'O

brake 136, but if brake 136 is thrown on by its operating niagnet, it will be thrown off by throwing the main brake 33 on. In other words, if the machine is stopped automatio cally by either of the maoazine switches, to start the machiinke agaiii tl@e magazine switch which has CIOE@D should be opened eitlier by putting a record or records in the magazine 85 or taking records dut of magazine 87, as 10 the case may be,, and then throwing the main brake 33. to off position. The stopping of the machine will not, of coursd, prevent the shifting mofor 90 from couipletiii itseyele and bringing the arm 88 to its central or 15 normal position. .A,t 140 (Fig. 7) is.provided what I shall call a transit switch since it is operated duriiig the transit o-f the recorcl from the metgazine. This switch after being closed is izo tripped Qpen by @ projection 141 on the arm 88. The swiieh is held in closed position to which it is rpoved by the edge of a large record engaging a roller 142 to. close the contacts 143 by a latch 144 wliieh is sprin(y pressed to latching position. The switch 140 is spring press.-d s6 as, to normally assume the open position when releas6d. As -i large record is --rawn from the inagazine 85, therefore, it enga(,res the roller 1.42 and 30 moves @switch 140 until contacts 143 are bridged and the latch 144 liolis it ill this position. lvhen the arm returns to witli@draw another record from the i-nagazine, the projection 141 engialgeps the end 145 of the it 10 35 latch and holds erative, ,illo-v@ing tlle switch 140 to opeii if it should be close(]. When the ' 'arm 88 starts back witli a record, the latch is release'd in tiiiie to allo-tv it to lateli the swit(-@h clos- . ed, if it sliould be close(I 40 by a large record. If a small record is witlidraivn fron-i the magazine, the switch 140 is iioit op@ratecl btit reiiiqin in its normal opeii position. As thus constructed iind arranged the op45 eration of iny automatic plionograph is as follows. As-qiime that,the maga'zine 8r) has been supplied with records of botli sizes, ten and twelve incli, and th-,it a record. of eith@r size say, foi- instance, a t'welve inch riO record, is placed in playin- position on the table. The needle is now placed at the beginning of the recofd. Since a large record has been placed on the table to be,played fir,lt, the switch R' ivill be moved by tlie, Itig 55 79 to the full line position sh6wn 'in Fig. 8 aga-inst the tension of the spring 80. The opierating le-v6r 32', being in the stopping tion' wiR be in the conta6t el ips 32 which posi also act to hold the lever and -parts mov.60 able,.therewith in position. Wlien the lever 32' is in the stopping position, the'l,ug 68 is in the ]position in which it has moved operviting@ members 65 so that it will operate the middle switch element 63@ of the limit o@. switp@ L. Even though the Itig 68 h,,is been parried further than this position in the 1,,ist operation befo@e stqppin ,,I.so as to open the last switch element 62, eif the machine is stopped it will'be taken back to the stoppino, position of the middle switch element sin(@@ this is the only position in which the lever 32' can be operated to stop the machine. If now the lever 32' is pulled outward to the position shown in Fig. 3 to start the machine, tbree thirigs will happen; lst. The brake lever 33 is operated to release the brake and, allow the macliine'to start. 2d. The limit switeli operatino, lug 68 is clatped to the tolie arm and will, theri Flo be in the position in which it will open the middle switch elem.ent of the. limit switch upon its return. 3d. The switch R' wliieli has been moved 'to the full line position'of Fig. 3 by tlle Iii(r E,-) 79 is latclied in that po--ition and will rem' aiii there, tintil the lever 32' is ag,,iin oper te( to stop the machine. A fourtli thing miglit be mentigned, viz, that tlle pin 79' whicli lias prevented the ae-: cid@nttil diaplacenient of switch L wliile the machine was siopped, is remo'ved if in fact the Rwitcli L had been moved far enotigli so that it cotild be displaced and the pin lias according]' iiiov-ld to the locking position. We will noiv asstime. that the parts frct iii the positions sliown iii Fig. 3 and tlle bi-ake being released the machine starts. As tile need]4@ moves inward towaid the ceiiter, the operating lever 32' and lug 68 whicli is now loo clamped to the tone arin move in a elockwise direction, the 'lever 32' movitio, in tlle slot 76 and the Itig 68 moving away roin it.,; inititil positioii.. The lug 79 which oper@te(I the switeli R also moves aw ay from tlle s,,viteli operating ,trm 81 but the switch R' is now latched in the position Eh,own-in Fig. 3. The needle now being moved inwai-d, tli4L@ fixed Iii,(r, 67 oii the tone arm approaclies the limit switch Layid when the end of tlie. ree- 110 ord is reached, and the inner spiral 67' on the record quickly tlirows the tone ,trm over to its final position, the Itig 67 will engage the pi,ojection 66 on switch L and close the sw'itch, that is, all tliree switcli elements if ]I.,; they should liappen to be open, will be simuhaneotisly closed. In the meantime wli le the recofd is bei@(r played and t,lie sl)rillg inotor running d@'wn contacts 17 aiid .18; have come into metallic engageinent. - and I-30 made the circuit at that point.

The record wliieh lias just beeii. played is sliifted t6 the 1-i(rilt into magazine in 87 (Fi-. 7) and thci record shifting arm'88 mov.es bad@ t6 the left to witlidraw a record iroiii the iiia(razine 85. Just before the arm 20 reaclie the position ' in wliich it picks up the record,'the projection i4l oii the arm 88 ti,ips the lateli 144 aiid releases the transit switch 140 if it should be in the closed posi-' tion. Since we are assumin(y that this t5 25 switeli is op2ii, the operati(n of the lat(!Ii lias no effect,at this time. We will assume, liowever, thit a, large record is now witlidrawn fi-om the ma(razinct. As the ariii 88 moves back to the r-'glit cari-yin(y Nvith it -,i. .9.0 lai-ge record the latch 144 whieli lias been liel(i iii iiiopei-ative position is released and the ed-e of the record strikin- the roll@r 142 on. the transit switeli closes tile'switcli dt the contacts 143,.

This is as it sliould be since the second re6ord is r).3 a larg6 one, the same as t] le first. It -,Vill be understood, Of course, that t-he contactg' 17 and 18 do not open at this time, the stopI)ing being co.ntrolled entirely by switch L. .

In this case the circuit would .65 -be broken -when the first switcli eleiiient 64 is opened. Since the distance travelled by the tone -afm bet-ween the operation of switeh element 63 and the operation of switch element 64 is the d,stance betiveen the startinposition oii a small - record :ind the startln(y 4'0 position on -a large one, this -%vill stop the tone afm aiid lower the needle at th(@ startin.-@ positioii of a small record.

The switeli It would now be in the dotted line position- 'aiid the two sw.itch elements 85 62 and 63 become the operative ones; 63 for the small records and 62 for the large ones; the spacin- between the operatin- positions of swit@li elements 62 and (53 being the same t!> as betweeii cleiiients 63 and 64. 90 In otli.,-r iv6rds, since the lug 68 is aliva set upon the s'tartin(r of the machine in t@ies position in whicli it will trip open the middle.switeli cleinent 63 upon its return, the torle- arm will always be stopped at that 05 I)oint if the i-ecord to be played is the same size as the first record (the one for wliieli' tlic, ' switch R is set) ' If the record to be played is a larger record than that first i,ecord, then the tone arm returns until 100 switcli element 62 is opened, but if the record to be played is smaller than the first r.,,cor d then the tone ai-ni is stopped ivlien the fii-st switch element 64 isopened.
