To all whom 'it may concern:

Be it known that I, JOHN A. WESER, a citizen of the United States, residing in the borough of Manhattan of the city of New York, in the State of New York, have invented certain new and useful'lmprovements in Graphophones, of which the following is a specification, reference being had to the accompanying drawings, which form a part hereof.

It has'been proposed to control the operations of a graphophone by means acting automatically and in proper sequence whereby the proper starting and stopping thereof is effected and different records successively placed in operative position. Such means have usually been mechanically connected to the actuating mechanism of the disk turn table and once the device was set in motion various controlling devices had to perform their respective functions before a different record could be placed in position and the parts reset. Further, in these prior devices, it was not possible to repeat a portion of the composition on the particular record in operative position. The transfer of records in such arrangements has usually been effected by the bodily movement of suitable 'frame supports therefor and the means to effect the movement of the frames when desiredk have necessarily been too complicated and delicate for general use and didnot admit of the application of the devices to any graphophone. Further, the cont-rol mechanisms have never been so related to each other and to a common source of power that those movements which should properly be cordinated and yet independent of other sequential control movements, could be initiated independently. Neither has any 'arrangement been provided to permit the operations of a graphophone to be controlled froma distance by an attendant.

Accordingly, it is an object of this invention to overcome the disadvantages hitherto encountered in automatically controlled graphophones and to provide a machine which shall be of comparatively simple construction, substantial in its nature, of relatively few moving parts, inexpensive to manufacture, invariable in its operation, susceptible of control at all stages of its operation and ata distance and generally of a character which shall commend" itself to users of all classes.

any desired place, the sound box together with the needle may be lowered tooperative position in engagement with the disk whereupon the composition thereof will be rendered. When desired, other pneumatically controlled devices may be set in motion to lift the needle from the record and permit the sound box to be returned to a predetermined starting position; the rotation of the turn table stopped; the uppermost record removed from its position on the turn table thus bringing the record immediately thereunder into operative position; the turn table released to permit its further rotation; and the sound box and needle lowered to engage operatively the uppermost record, after which the operations above outlined are repeated or modied at the will of the op erator until the lowermost record has been removed from the turn table.

In the embodiment herein illustrated the several control devices are actuated pneumatically, a switch being provided at any desired place between the source of power' and the several independent pneumatic controlling devices, whereby the latter are set in operation at will.

Further improvements will appear as this description proceeds, among which may here be mentioned the means for controlling the volume of sound to regulate theexpression, f

means to insure automatically the return of the sound box to any desired predetermined position with respect to the record and a multiple needle holding device for the sound box.

The invention will be more fully described with reference to the accompanying drawings, in which- Figure 1 is a view in plan of -a'graphophone embodying the present invention and showing certain of the pneumatic control-A ling devices, the latter being in the normal position immediately prior tothe rotation of the turntable.

In the following description the variousl parts entering into the construction `of van improvedgraphophone embodying the present invention will be described with referand the Several groups of i-elated'pneuniatic controlling devices.

For the. purpose of this description a graphophoiie of ordinary construction is Fig. y

herein ,illustrated1 being composed of the usual operating partsdisposed substantially iii their ordinary relationship each to each and performing their respective well known functions. y

As the description proceeds it will be evident that the invention is applicable to any Igraphophone of the disk-record type. The graphoplione proper may be disposed within a suitable cabinet a having a horizontal partition a therein for the support of the kusual operating devices and beneath which may be disposed the actuating motor (omitted herein for the sake of clcarness) for the turn table b,-the latter having a post b coincident with VitsvtaXis and adapted to eX- tend through theusual central apertures c of the disk records c which are supported by the table. 0n the horizontal partition a is also mounted the usual d having a swivel connection with its base CZ to permit its free movement in a horizontal plane and having swiveled thereto the usual goose-neck pipe d2 in connection with the sound box d, all as in a manner well known. One end of the horizontal partition a terminates adjacent a downwardly extending flat support a2 which may be provided with side walls ai and lined with a resilient covering at, for a purpose which will later appear herein. It should be noted here that while the relationship of the parts thus far described may be changed at will, it is necessary that the inclined open receptacle last described, comprising the floor o? and side walls fr, lie in juxtaposition to the turn table so as to receive the records therefrom, from time to time during the operation of the graphophone. j

A feature of the invention hereinbefore referred to and which might properly be de.- scribed at this point resides in the provision of suitable buffers designed to limit the movement of the sound horn in one direction so that the sound box may be stopped iio ment two such buffers are described, one, as i illustrated in detail in Fig. 8, being designed primarily for the` repeat of :in entire record disk, and the,` other, shown best in Fig, 1, being intended primarily for thc repeat fof portions only of the composi' tion of the record. The first named butler, herein designated generally by the reference character e, is mounted rigidly on the horizontal partition a and includes a horizontal tubular portion e in whichI is disposed :i spring pressed plunger .c2 having a suitable handle c3 at one end adapted to be grasped by the operator` and a suitable resilient cushion eL at the other end with which the tone arm d contacts as will presently appear. The tubular portion c has threaded therein a set screw ci by which the position of the rac ing now to the fingers Z and Z briey referred to above, it will be seen that the uppermost Vfinger Z is pivotallymounted on the finger Z on a stud Zi and moves upwardly with respectto the lower finger Z against the action of a suitable leaf spring Z5 operatively interposed between the two fingers. The normal relationship of these fingers may be fixed by means of an adjusting screw Z6 threaded in one finger Z and engaging the other' finger Z. i

The upper finger Z rests at all times on the upper face of the uppermost record, while the lower finger Z is adjusted with respect to the upper finger by means of the stud Z6, so that the lower finger has its outer edgesubstantially in the same plane with the under face of said record. When it is desired to remove the uppermost record c the bellows n is collapsed, rotating the vertical shaf't m and swinging the support m, arm Z2 and fingers Z and Z inwardly radially with respect to the record. The cam surface of the finger Z is so formed that the initial movement of the disk record thereon. is upwardly against the action of the upper nger Z and its spring Z5. This upward movement ofl the diskserves to bring its aperture c out of engagement with the vertical post b of the table b so that by continued inward movement of the fingers, the record is slid bodily toward the inclined support a2. As appears from Figs. 1 .and 2, when the record is slid outwardly to a point where it is overbalanced,'it falls on said incline and is guided in its movement to a position of rest by the side walls a3 thereof. By suitable manipulation of the controlling valve, hereinafter described, the

bellows n may now be allowed to collapse so as to swing the arm Z2 and the intermediate connections back to their normal position in which the upper finger Z rests on the disk immediately below the one removed.

The other parts before described may then be set in motion to render the composition of the uppermost record.

lt may be desirable at times to control the volume of sound in accordance with the nature of the selection and so the cabinet a, is here illustrated as provided with a shutter a" hinged in one of its side/walls. This Ishutter a is connected through suitable links n? to a. 'bellows o suitably secured within the cabinet. In the embodiment illustrated, when the bellows o is collapsed the shutter fr. is closed and for all intermediate positions of the bellows o when being distended the shutter is opened a corresponding eX- tent.

From the description thus far given, it is thought that the desirability of employing a multiple needle l, holder to permit a fresh needle to be brought into place quickly, will now be appreciated. One form of such a needle holder is illustratedin Figs. 16 and 17. This comprises an annular carrier p provided with a plurality of recesses p in one end to receive the needles, which may be secured therein by suitable set screws p2 and having the other end in operative connection with the sound boX d3 in the ordinary manner. In use, any one of the needles may be brought into operative position quickly with respect to the record by rotating the support p, as will be obvious.

A. slightly modified form of avmultiple needle carrier is shown in Figs. 18 and 19. This comprises a suitable yoke g carried by the sound boX Z3 and having journaled in its branches a holder g', in the periphery of which may be disposed a plurality of needles. The annular holder g is formed with two relatively movable portions between which are disposed the needles. These portions may be moved relatively by means of a suitable milled nut q2 in a. manner which will be obvious to a skilled mechanic and which need not here be illustrated in detail.

The parts constituting the Aimproved graphophone and controlling devices therefor having now been described with sufficient detail, the control system for these several devices will now be considered. In this connection reference is to be had particularly to the diagrammatic view of Fig. 3. In this figure, in the interest of clearness, the sound box and sound horn together with their controlling bellows have been shown in side elevation, while the break bellows, the record shifting mechanism and the expression shutter have been shown in plan. The master bellows is in the present embodiment adapted to be operatedmanually, but it is to be understood that any master bellows controlled by mechanical or pneumatic devices may be substituted. lSuch an arrangement wouldbe especially desi 1able when the improved graphophone is use in connection with a pneumaticpiano player or the like.

The master bellows r has connection, through suitable piping -r and r2 with a controlling valve or switch which may comprise a member a, secured for the sake of convenience on a table t or the like and having pivotally secured thereto a valve member s on which is pivotally secured a second valve member s2. rl`he location of the switch with respect to the graphophone and to the master bellows may be changed as desired. As shown particularly in Figs. 13, 14 and 15, the master bellows connection r terminates in a port s3 extending through the valve member a2 and adapted to be placed in registry with a second port s4 formed in the adjacent valve member s. The other connection 'f2 from the master bellows r terminates in a port s? formed in the valve member s, which may be placed in registry with any plunger e2 with respect to the sound horn d may be adjusted so that the movement ot the latter is stopped in one direction 1nvariably at a. predetermined point. When it is desired to repeat a portion only of a record theother butler device f is preferably employed. This last named butter comprises a vertical stud f carried rotatably by the horizontal partition a and having threaded therethrough a plurality of horizontally disposed butler studs g carrying suitable cushions g at one end to contact with the tone arm d in a manner lsimilar to that pointed out with respect to the butter e. By employing the buli'er device j as many predetermined repeat positions for the sound horn may be secured as there are horizontal threaded studs g and so, by rotating the butter device to bring the proper cushioned stud in operative position for successive records. the favorite portions ot each record may be repeated without interrupting the rendition thereof to adjust the stop. lVhile it has been stated that the buffer devices c and j above described have especial application to the repeat/of records under cer-- tain conditions it is to be understood that either may be used as repeat stops under all circumstances.-

The sound box d3 with its needle may be lowered or raised from operative position by means of an arm it which preferably eX` tends through the goose-neck pipe (Z2 and has one end lying thereunder so that when this last named end is raised the sound box will be'raised .in a manner similar to that employed when the box is raised manually by the insertion ot a finger under the gooseneck pipe. The other end of the lever z. is secured to the movable member h of a bellows h2 carried by a suitable bracket (l secured on the sound horn Z and movable therewith. This bellows il? is normally held in distended position by a spring h3 as is usual in such devices. When the bellows lz? is in its distended position as is illustrated in Fig. Il, the sound box d3 and its needle rest by gravity in operative position on the tace ot the uppermost dish record c. When it is desired to raise the sound box d and its needle Jrom this position the bellows It* is collapsed. thus swinging upwardly the outer end of the lever It together with the goose-neck pipe (Z2 which rests thereon. When the needle -is released from its en'- gagement with ner just pointed out, the tone arm fZ is brought under the action of a suitable spring` (Z5 which serves to move the same toward vits initial position. ,als pointed out before. however, this Swinging movement or" the tone arm al may be stopped either in its inward starting position. as or at any predetermined repeat"` point` as by means of the butter f.

` sition by the record disk in the n'ianb v the butler e,

To stop the rotation of the turn table D or to permit its rotation, a suitable brake i is provided by two bellowsj and la, lying in juxtaposition to each other and supported. on the horizontal partition a. The Inovable member jof the bellows j may carry the brake t', and its movable member is so disposed with respect to the periphery ot the turn table as to bring the brake in engagement therewith when the bellows is in its distended position. rl`he bellows j and c are normally held in their distended posprings jg and 7c respectively`v as will be understood. To permit the turn table b to rotate under the action of its motor, the bellows y' is collapsed, thus withdrawin the brake i from engagement with the periphery of the table. Vllhe bellows j is held in this collapsed position by the. engagement of a suitable lent spring is earried on the movable member j which has a slot adapted to engage releasably a stud j" mounted on the immovable member of the bellows, as appears most clearly in Figs, ll and 12. lVhen it is desired to start the rotation of the turn table b the bellows 7.: is collapsed so that its movable member 7a2 which carries aV stud 7c3 in its end, will bring the stud its in operative engagement with the leaf spring ja so as to disengage the latter from the stud y" and permit the bel lows y' to become distended so that the bra he @l is brought into Contact with the periphery of the turn table b.

After the composition et the uppermost record c has been rendered and perhapsaepeated wholly or partially at the will of the operator, itv is proposed in accordance with the present invention to have the same removed by suitable means also under the control of the operator so as to bringl the dislr immediately thereunder in operative position with rospo-1st to the sound box d and its needle. llllhen this is brought about,

' bed may be re the movements before der, peated with respect lo the new dislt. 'The mechanism for removing the uppermost revord comprises a cam linger Z which is adapt-- ed to be slid under the record and a prima pressed cani finger Z carried thereby and reversely disposed with inspect thereto to engage the upper 'face oi' the record. The finger Z is adjustably 'secured to one end of an arm Z2 by means of a set screw Zi'. The journaled loosely other end ot the arm in a suitable support m .secured to a vertical shaft m' rotatably mounted in a bracket u" carried by the cabinet a (see Fig. 9j). 'l`he shaft 'nt' in turn. is operatively connected to a bellows fn/ also secured to the cabinet a, through suitable links m,2 and mf". The angular relation of the support m, to the shaft m as well as the angular relation ot the linlr m2 thereto. may be lined by suitable set screws m4 and mf' respectively.

in the bellows h2 is a pipe connection u, by

which the bellows h2 may be collapsed as will later appear. leading therefrom a branch connection u which terminates in an immovable valve member h5 carried by the bellows h2. This valve member h5 has a port 71, with which is adapted to register a port zf formed in a movable member las pivotally secured to the immovable valve member h5. The movable valve member its is normally held so that its port k7 is out of registry with theport Itv of the immovable valvemember it by means of a suitable leaf spring h".
