To all whom it may concern: Y y Y 1 Be it known that I, JULrUs RoEvER, of the city of New York, county of Kings, and State.

- 1.5 and in which mechanism is used for carryin the re roducer along-in a direction. aralle with t e record which is being playe upon. My invention relates more es eeially' to machines of this class which t e reproducer has a constantrelation tothe record, but the stylus is lifted out of engagement with the record or dropped to engagement, as required. 'Heretofo're 1n machines of this character there has been considerable complexity in the mechanism for actuating the machine for movin the reproducer along in a direction parallev with the' record, and especially in the meansfor lifting'the-st lus out of engagement with. the record. and rop ingv it back to smplace. In some-cases sprin p ames of various kinds havebeen used to old'the drivin mechanism-,in pro er relation with the recor to 4be driven, an -1 a complicated system of levers has been-used vto lift. and drop 'the astylus..

' .This particularinvention is especially intended to overcome .some of the difficultieswbove named, and' roducea simple mechan ical mechanism for riving the record, for per# 40. mitting the driving mechanism to be placed in and out of engagement with the record to be driven, andfor actuating the stylus, that is tera-isc and lower it as desired.

. My invention also rovides'or automatically disen aging ythe driving mechanism of a record' attghe same time the st lus is lifted; I alsoprovide a simple means or dropping the stylus at the exact oint required inv any record', so that when ,1t is dro. ped the' playing l 80- hegins' immediately a ter' the record is started sufficiently togmake the pitch'and' time correct. Y

Withfthese ends in view my invention con- B. phonographconstructiomwhichwill habere-4 owing is a full,

ing means, an any suitable motor or source 'of power. It sists olf certain improvements inmultiple ,wi-l

inafter described and the novel features claimed Reference is to be had to the'accompanying drawings formin a part of this specification, in which siml ar reference characters indicate corresponding parts in all the views. Figure 1 is a plan view of the structure embodymg mylinvention. Fig. 2 is a cross section on the line 2-2 of Fig. 1, and showing also a 'segment 'of the record wheelwith a -65 series of records thereon.- Fig. 3 is a longitudinal section partly in elevation of my irnproved structure, showing a )art of the rec ord wheel, and in proper re ationgt-hereto, and with the driving mechanism out of engagernent with the record to be driven. Fig.

-4 is a similar view to Fig. 3, but with the driving parts in engagement, and Fig. 5 is a cross section on the line 5-5'of Fig. 4.

In the `drawings I have shown iny invention suppor-tedon a post 10, which carries a horizontal frame extending above the to of the record wheel, to be resently referre to, said frame comprisin t e cross bars 11, the vertical arms 12, an the tie rods 13, which', go extend vlongitudinally, and one of which is preferablysquaredas shown at I3, to provide fornonveniently attachin -oertain parts to be hereinafter described. his frame eX- tends horizontally over the top ofthe record wheel 14, which, sofar as this particular invention is concerned, can be of any approved character, and v whichV 'carries a perlpheral series of individually rotatable records 15 of the usual kind, these having disks 16 at- 90 tached, by which they can be numbered and identified. My invention relates, however, wholly to the matter carried bythe frame above referred to and described below. This frame Vcarries driving mechanism which en- 'gages a disk- 17 on the spindle of each reco'rd 15, as thelatter is bbrought to place; and as shown the disk 17 is .driven by the friction -Wheel 18, which is carried by a lieXible shaft com rising the sections 19, 2() and 21. The 100 section 19 has a socket in one end to receive the spiral section 2Q, which con les onto the section 21, and this' is mounte in suitable bearings 22 intwo of the cross-bars 11. The flexible driving shaft just described. is driven by a ulley 23', or equivalent'driv- (i) the pulley can connect with be observed. that to disengage the driv' the friction wheel 18 from the disk 17, and in vthis way I obviate the necessity of using spring frames and other structures such as i have been heretofore used.

To provide for lifting the free end of the flexible shaft, the section 19 extends through the free end of the swinging arm 24 and this is pivoted as shown at 25 on the rigid arm 26 of the horizontal frame above referred to. To provide for the necessary freedom of movement,i the hole through the arm 24 is rather large, and the shaft 19 is centered and j ournaled between the anti-friction rollers 27 which are pivoted in the arm 24. The frame carries a reproducer carriage 28, which has a movement longitudinal of the frame and par allel with the several records 15, and the carriage can be mounted in any convenient way. As shown it has ears 29 sliding on a guide rod 30, and an ear 31 on the under side sliding on a guide rod 32, as shown clearly in Fig. 2. The carriage supports a re producer 33, which can be of any approved kind, having the usual top part 34 to connect with a horn. T he reprodueer. is stationary with relation to the carriage 28, and it supports a tilting lever 35, which has a stylus 36 to connect with the record, and which is carried by a plate 43, to be presently referred to. The carriage 28 is moved backward and forward from a screw 37, which ,has the regulation thread to move the carriage forward, and a coarse cross thread 38 to effect aquick return of the carrlage. This arrangement 1s not claimed as new. The screw connects with the driving shaft by gears 37a and 37'), and the' thread of the screw engages a blade 39, the shank of which is held in the su port 40, which is secured to a post 41 on t e carriage 28, and as the blade follows the thread of the screw the 'carriage is moved forward or backward, as

the case maybe. When the blade reaches the end of the screw it is guided into engagement with the necessary thread by-'the cam mechanism 42, and this is Anot here claimed. The reproducer stylus is carried by a drop ever or plate 43, which is pivoted to the carl ria e 28 at one end as shown at 44 in Fig. 2, an at its free end the plate has an upwardly extending flange 45, to which is secured an arm 46, which rides on the thin upper edge of the plate 47, by which the rise and fall of the plate 43 is regulated. Obviously the plate 43 can be'given any desired configuration, so lon asits free end has an engagee ment with t e plate 47. The plate 47 has a vertical movement on the squared part 13EL of the frame, movement the yplate has slots 48 which receive screws 49, and these enter the part 13l just referred to. The plate 47 is narrower at the middle than at the ends,` as shown at 50 in Figs. 3 and 4, and to provide for raising and lowering the plate it has cams 51 near the ends, which engage the rollers 52 on the arms 5 3, and these extend downward` from the top plate 54, which slides longitudinally on the part 13a. The movement of the top plate is limited by screws 56 which extend through slots 55 in the top plate as shown in Fig. l. 0n the top plate, preferably near the ends, are posts 57 which receive the abutment rods 58, which have upturned ends 59 to engage the striking arm hereinafter referred to, and the rods 58 can be adjusted and are 'held in place by the binding screws 60. The bent ends 59 of the rods 58 are struck by the striking arm 61, which is carried by the post 62 on the carriage 28. It will be seen that by this action the plate 54 is in one instance moved to the right, in which case the rollers 52 striking the cam 51, lift the plate 47, and the free end of the plate 43, so as to bring the stylus 36 out of engagement with the record. This occurs when a record has been traversed and a tune has been played.c When, however, the carriage 28 reaches the end of its return stroke, the arm61 strikes the opposite or left hand rod 58, the plate 54 moves in the opposite direction, and the plate 47 and the late -43 are dropped so as to bring the stylhs into engagement with a record. lt is desirable to have the driving mechanism of the record disengaged at the same time that the stylus is raised from the record, and to this end a cam 63 in the shape of a bent rod, is secured to the post 64 by means of the binding screw 65, the said post being on the raised end 54a of the plate 54. This bent rod 63 is arranged to extend underneath the arm 24, and so just asthe stylus is lifted, in the manner already described, the arm 24 is also raised, and the friction wheel 28 lifted out of engagement with the disk 17.

In order that the stylus may drop in the right place and engage the record after the latter has started, that the stylus will not drag along the record, l use a gage which as shown is in the form of a U shaped clip 66, which is fastened to the outer side of the part 13a of the frame by screws 67, and the clip extends beneath the part 13'a and then upward parallel with the plate 47. The inner side of the clip is inclined as at 68, and when the plate 47 drops so as to drop the stylus into engagement with a record, the arm 46 strikes the inclined part 68, and is thereb guided so as'to push the carriage 28 slightfy and bring the stylus into the correct place. The ga e- 66'is longitudinally adjustable in order t sult may b e best attained, and an easy means of adjustment is shownin Fig. 3 in dotted lines, in which the gage has a longitudinal slot 69. to receive the screws 67. Obviously the gage can be differently made, and the essential thing is simply to have the inclined surface'engage' the art 46 and regulate the dropping posltion of) the stylus 36.

at the above reis started well, the stylus is dro esami From the foregoing description' it `'will -be seen that I have Shown a very practical and simple means of accomplishingthe results at first referredto, thatzis to say, the dropping vof the plate 47 permits the'frictionpwheel 18 record has been traversed, the driving parts are automatically disengaged.

Having thus fully described my invention, I claim as new and desire to secureby Letters Patentz- 1.` In a machine records thereon, of a flexible shaft connected with a source of power and having an operative connection with each record, and means 4for breaking the driving connection between the shaft and the record by exing the said flexible shaft.
