and WALTER THOMA, citizens of. v the United tion.

The present invention relates generally to f phonographs or other sound reproducing machmes, and has more particularly reference v States, and residents of Carlstadt,'. in the county 4.of Bergen .andState 4of New Jersey, have invented certain new and useful Phonographs, of which 'the following. is a specificato a multi-record or repeater phonograph. such as is' disclosed in Letters Patent No. 873,969 of December 17, 1907.

The main object of the inventionis the production of a machine, automatic through-.

ing period so that the rotation' of the record carrier will move the alinement device a surfivcient distance to position a new record after which the locking devicelocks the'alinement device again.v In the preferred'embodiment` the sound reproducing mechanism. isutili-zed to 'release the locking device and to turn the record-carrier.

lnorder, however,.to allow for slight discrepancies, due. to lost. motion `or wenn. we employ (an intermediate driving mechanism for operating the individual records which will compensate-for discrepancies in size or positioning of the parts. i The intermediate driving mechanism is carried on the free end of an arm which is loosely pivoted at the otherend. This intermediate driving mechanism rests on and is in engagement with transmission mechanism onthe driving shaft and is adapted 4to engage withtransmis'sion' mechanism on the records as they are successively presented thereto.

The intermediate driving mechanism is thus held yieldingly in engagement with its cooperating members whereby discrepancies in size and position ofthe parts are compensated for. Other features of construction will appear ,as the specification proceeds.

1 indicates an intermittently rotatable record carrier holding a plurality of records 2 which are sup orted on the spindles. .i

- 4 denotes tile sound reproducing mechanism the main supporting part of which is in the form of a sleeve 'sliding .on the shaft 6. As here shown the sound reproducing mechanism carries two 'arms'7 and t3,l onccf which is provided wlth the tine thread. follower 9, an

the other 0f- -which carries .a second or repeater thread follower .10. .The record carrier is mounted on the shaft 1]., while 12 and 13 indicate respectively the. main drive or feed screw shaft and the double-inversely threaded repeater screw shaft.

Mounted v fast on the shaft-11 by means of the key 14 is a ratchet 15. .Surroundingthis ratchet isa loose sleeve having the cam groove 16 and' provided with the spring seated pawl 17 adapted to engage with the teethof the ride idly over the teeth when 'turned in the other direction. Y

The thread follower has a tooth -21 which enters the threads of the repeater screw.`

@l5 and' having its movement limited by t ie pin 28, on which latter4 the lever 19 is mounted.

nose is allowed a certain amount of lateralpl'ay and has an'outwardly turned projection 29 at its lower end.

, v When the sound reproducing mechanism' comes to the end of its forward stroke, the trip on the repeater screw WilYengage with theprojection 29 of the nose 27. The advance of the reproducing mechanism is .very gradual owing to the line threads of the feed screw, but the tri 3() need only engage the nose 2 1? very slight f since' t-he latter will be turned sidewise owing to-the fact that it isoo'sely-mounted and' the trip 3,0 will theref ebeable lo get agood grip under thepro je tion 29 thereby lifting the arm S and the sound reproducing mechanism. In case the trip does not engage the nose 27 sufliciently the latter will merely sl'ip off without disturb the advance of the reproducer and on the ext turn the latter will have moved forward 'auciently to enable the trip to properly en- ]gjge the"nose 27. lllhen the arm S is thus ted the thread follower 10 will slide into,y engagement with the thread 31 of there-i ,peater screw 'the weight of the parts causing the lever 19 toturn around its pivot to effect this. The .sound reproducer wvill now be Y moved ljffu and this motion will continuo until the `.;ead follower encounters the cam surface 32 of the repeater screw which will turn the follower around its swivel-and guide it into -the reverse thread 33 of the screw. Theadvance movement of the reproducer is thus commenced.vv During the return stroke of reproducer the lower end of the tail 22 will have been-moved inward by ,the cam 33. This, however, has no effect on the Upon the forward stroke of the repro( ucer, the tail 22 will pass on the other side of the cam 33 and when the surface 34 is encountered the lower end of the tail 22 will move. outward thereby causing the arms 24 to engage the v rojection 25 of the follower 10 thereby ho ding it from turning on its swivel. The tail can therefore move no further, inpendently, and the motion is then continued around the center 28 with the result that the follower is moved sidewise off the repeater screw. This causes the arm 8' and arts scenes the reproducer to descend, whereby the follower 9 will engage with the feed screw 12. On the end of the shaft or screw 12 is a gear 35, and on the end of each record is a friction roll'36. 70

37 indicates an intermediate drivingimechanism mounted on the free end of the arm 38 pivoted at 39 on the bracket 40. This intermediate driving mechanism consists of a gear 4,1 adapted to engage with the gear 35 75 on the shaft 12, and a' friction roll 42 adapted to engage with the friction roll 36- as they are successively brought into contact therewith. Thegear 41 and roll 42 are mounted on the same stud 43 and move together. The intermeshing teeth of the gears 35A and 41 should be long enough to allow the friction rolls 36 and 42 to bo always in engagement notwithstanding any"' `yielding movement of the intermediate device due to discrepancies in size or position of the parts. The weight. of the intermediate driving mechanism will I usually be sufficient to maintain contact, but if desired a spring 44 may be employed. The rotatable alinement device and the locking 9.) means therefor are constructed as follows: Mounted on the stud 45 is the Geneva stop wheel 46 adapted to be turned at intervals h v the projections 47 on the record carrier. lWhen the'carrier is tinerh'the projection i7 9:, in engagementwith the Geneva stop wheel will turn it part way, and the next projection 47 will turn it the remainder of the distance until a lo: lhing device, to be described, acts lo lock the parts. Each step of the record cm2 100 rier is sullicient to bring the next record to be played into engagement with its driving means.

43 is a locking pin adapted to engage with the notches on the Geneva wheel asthev are 105 brought into alinement therewith. This locking-pin is carriedliy the pivoted lever 4U. This lever is adapted to be moved h v :1nother lever 50 pivoted atv 51 and provided with the two arms 52 engaging the lever 4l). llc A. spring 53 bears against the lever lfiind serves to hold the locking pin 48 in engagement with the Geneva stop wheel; or serves to move the said pin into engagement therei with when a notchof the said wheel comes 11.5 intd alinement therewith. Means for releasing the locking device arc provided taking the form of a trip .54, in this instance' carried by the sound reproducing mechanism. This trip is pivoted at 5.5 and has a stop 56 120 which holds it from movingiout of the way when it encounters the lever 5() on. the return stroke of the sound reproducing'mechanism. When this trip engages with the lever 50 on the return stroke of the repro- 123 ducer the pin 48 will bc withdrawn from engagement with the Geneva stop wlieel, 1nd the record carrier is free to turn the said wheel. On the forward stroke the trip 54 will ride idly over the-lever 50.

. shown) is in engagement with the recordv 4The voperation is as followsz' During the' sound reproducingperiod, the pin 48 is locked withl the Geneva stop wheel and the record carrier is prevented from turning. .One of the records is rotated by the intermediate driving mechanism, the stylus (not which is rotated, and the sound reproducing 'mechanism is' advancing on its 4forward stroke by the thread follower 9 engaging with the feed screw shaft 12. As the as ound re-` producer comes to the end of itsstrcke the trip willlengage the nose 27 thereby'lifting the'sound reproducing mechanism up, bringe. ing the follo'wer`9 lout of engagement with the feed screw shaft 12 anddisengaging the sty lus from the record being played. By reason ofits own weight the thread follower 10 will slide into Aengagement wit-h the thread 31 of will enter the cam groove 16 thereby turning 25.-

the repeater screw yand the sound reproducing mechanism will commence its return movement. As it travels'back the tri 54 will release thelocking device, and thepin 1.8

the recordcarrier and bringing another reco rd into engagement with its individual,

driving means; The locking device will then lock; the Geneva stop wheel and record carrier.V When the follower 10 reaches the cam' surface 32 in the re eater screw the vmotion will be reversed an the sound reproducing mechanism will start forward again. On its forward stroke the tail 22` will pass on the outside of the cam 33 and when the -Surface 34 -is encountered the' tail 22 will clasp the follower 10 to 4prevent itfrom turninggg,l after which the said follower will slide out of the thread 33 thereby lowering 4the sound rew producing mechanism and causing the follower 9 to engage with the feed screw 12' and the stylus to engage the record to be played. It the pin 18 is removed the machine will not turn the carrier and the recordr already4 played will be repeated. Motion is imparted to the device by means ofthe pulley 57 on the main shaft .12. From there the motion is transferred tothe repeater shaft by means.

of gears 58 and 59.- Whenin its downward position, the sound reproducing mechanism `is artially supported on the rail 60.
