ism wherein provision is made for winding the spring which serves to actuate a machine element, such as the record ofa phonograph, by means of a motor which will operate for a predetermined period of time when set in motion, thereby to give to the spring serving to.

actuate said element a predetermined tension.

In the accompanying drawings my invention is shown appiied to a phonograph of well-known type employing a disk-form rec-- ord.

In the drawings, Figure 1' represents a side elevational view of a phonograph and the mechanism appiied thereto in accordance with my invention; Fig. 2, a reverse side elevational view of the same; Fig. 3, aplan view of the same; Fig. 4, a frontview of the same; Fig. 5, a broken section taken, as indicated, at line 5 of Fig. 1, showing a controlingwheel, which serves to control the circuit of the electric motor shown, and a stop-actuating lever employed, said view showing also the'operative parts adjacent to said wheel; 6, arear view of the machine; Fig. 7, a

v ew similar to Fig. 5, showing a different position of the parts; ig. 8, a broken sectional view taken, as indicated, at'iine 8 of Fig. 2;

Fig. 9, a similar View showing the parts in a different position; Fig. 10, a view showing the parts in Still another position; Fig. 11, a broken section taken, as indicated, at line 11 of Fig. 10; and Fig. 12, a simiar view showing the parts in a different position.

The construction illustrated comprises a phonograph D of known general construction, having a disk-form record D, a an 'ord-bearing disk D 2. record-bearing actu ating-shaft D actuated by a pinion D}, a cylinder D equipped with the usual spring (not shown) and with a gear D, a pinion D ber F against the tension of its splr driven by the gear D and in turn driving a gear D meshing with the pinion D, a governor D actuated by gears D from the shaft D, a horizontal winding-shaft D equipped, Fig. 6, with a pinion I)", meshin with a pinion D through the medium 0 which the spring is wound in the usual manner, and a reproducer I), mounted upon an arm D and cooperating with the record D; an electric motor E in an electric circuit E, energized from any suitable source and equipped with normally separated contact members E E a worm E on the shaft of the motor E and meshing with a worm-wheel E secured on the winding-shaft D; a contact-actuating lever F, Figs. 3, 8, 9, and 10, e uipped with an insulatiomfinger f, against w wheel F. for the lever F, bearing a lateral annular flange f, providedwith a notch f adapted to receive a lug f, on the lever F,

said wheel being provided peripherally with ratchet-teeth f; a spring held actuating rich the contact E bears; acontrolling pawl F joined by a pivot f 5 to the wheel hi and serving to actuate the wheel f,- a sprin actuated cam-retracted member F", throng the medium of which the member F is actuated in the operation of closing the motorcircuit, the member F beingactuated by a spring f" in said closing operation; a spring l tending normally to pull.the free end of.

the member F forward, so that when said member is withdrawn by the controllingwheel, which will be later described, a sh0ulder will engage a shoulderf on a loop or guide a: on the lever F,thereby to effect movement of the lever F when the member F returns under the action of its spring; a cam F Figs: 6, 11, and 12 .on the member F with which: engages a cam F, formed integrally with the wheel F, whereby the free end of the member F is forced rearwardly after the wheel F starts to rotate, and the lug f 3 is en: gaged by the flange f of the wheel; a stop-. actuating cam F on the member F which serves to elevate a-stop F whose upper end will thus be brought into the path of stops on the record-supporting plate D ;'a wheel G, Figs. 5 and 7 servin through the medium of a lever G, to with raw the meming at the pro er time and servin also, t 'me ium of a leverGr an a pawl G to with rough the draw the latch Gof a stop-actuating leverG i a gear'G formed integrally with the wheel G and actuated by a pinion G secured on a shaft G", equipped with a gear G", which meshes with the gear D, by which it actuated; a stop H, connected with the lever G", Figs. 1 and 3 which stop coacts with stops on the record-supporting disk D and a pivotally supported reproducer shifter J,

' 'outer ends project somewhat beyond the circumference of the disk, as shown in Fig. 3. These stops may be engaged by either, or both, of'the stops F and H. The function of the stop His to control the movement of the record of the phonograph in ordinary use, and in eoin-controlled machines the'stop H is actuated ordinarily by a coin through the .medium of the lever G the coin being directed to the free end of the lever by a chute a, as indicated by dotted lines in Fig. 1. The

function of thestop F is to prevent further rotation of the record after the machine has once operated until the motor has been set in operation to rewind the spring of the phonograph, whereby a desirable tension is always maintained on the phonograplrspring, the spring never being allowed to run down. The worm-driven wheel E takes the place of the winding-key of the ordinary manuallywound phonograph of this type.

The motor-circuit may be provided with a fuse. (None shown.) The contacts E E preferably comprise two normally separated spring-metal members, the member E being capable of being forced into engagement with the member E and returning under its own resiliency to the open position.

The contact actuating member F is equipped near its pivot f with a short arm f and the spring F joins the armf to the free end of the member F Thus it will be understood that the lug f tends normally to enter the recess 2 in the flange fofthe wheel F f", carried by a frame member f Said wheel is guarded against retrograde movement by a spring f The pawl F is held in engagement with the ratchet-teeth f by a spring The-member F has one end freely movable in the loop at of the member F. The stop F 3 is in the form of a vertically-movable rod having a collar 8 near its lower end, Fig. 4, whichjrests upon av guide 3 and holds the lower end of the stop high enough to permit the. cam F to-pass beneath it during the movement of the' membcr F under the action of its spring, as indicated at Fig. 10.

The wheel F is mounted on a stud The Wheel G is rovided on its front surface with a camug 9, adapted to engage the upper end of the lever (1 and actuate said lever during each revolution of said wheel. The parts are-so timed that the wheel G makes one revolution by about the time the record has been completely traversed by the stylus of the reproducer. When the lever G is relieved from the action of the camlug g, the member F is permitted to return under the action of its spring and close the motor-circuit, whereupon the circuit is maintained closed the alloted period by the wheel F, the cam F whereof o crates in the meantime to release the shou der f of the member F from the shoulder f S of the meml er F. The wheel G has a smooth circumferential surface g, upon which rides a roller g-, carried by the member G the periphery of the wheel being provided with a recess g which the roller may enter after the wheel completes its revolution. The parts are so timed that the roller will enter the recess 9 an instant before the cam-lug g releases the lever G, and the lower end of the lever Gis provided with a locking-shoulder g, which engages a shoulder 5/ with which the member G is provided, so that although the wheel G may allow the member G to' rise slightly before the member G is released from the lug 9 this action nevertheless will notbe permitted to occur until after movement of the lever G. The lever G has its free end held normally ele vated by a spring g, as shown in Fig. 1. The latch G is provided with a locking-shoulder (1 which corresponds with the elevated position. of the lever G and a locking-shoulder l g, which correspondswith the depressed position of said lever. The pawl G is connected by a pivot g with the ever G and is provided with ahook g adapted to engage a lug g, with which the locking-pawl G is provided. The pawl Gv is supported from the frame of the machine on a pivot 9 and is provided with a short arm connected by a spring g with the pawl G, whereby the tendency of the lower end of the pawl G is to move-outwardly and the tendency of the free end of the pawl G is to move upwardly, On the frame is provided a stop g, which is engaged by the pawl G to cause it to release its hold upon the pawl G during the upward movement of the free end of the lever G The purpose of. this action is to permit the pawl G to assume its normal condition in readiness to lock the lever G when the latter is again depressed. The s rin g, connected with the lever G an wit a projectiong Fig. 1, on a frame member, tends normally to elevate the free end of said lever.

The stop Hcomprises a vertically-movable IIO izo

bar provided with a slot,,through which I member J having pivotal connection- 7' with the member j in front of the pivot it The front portion of the member J is equipped with a cam j, having an inclined surface 3' which tends normallyto hold the arm D of the reproducer over against an adjiistable spring-sto j at one side of. the frame 7', whereby t e reproducer is'held in a proper position to be lowered u on the record at its outer margin. \Vhent e stop-actuating lever G is depressed and the spring-driven train of the phonograph allowed to operate the phonograph, t he wheel G is caused to' turn, owing to its connection with the drivingtrain of the honograph, and the roller g? is forced out o ,the recess 91 in said wheel, being moved from the position shown in Fig. 5 to the position shown in Fig. -7. Thisimmediately depresses the .front end of thereproducer-shifter through the medium of the connecting fnember J, which is actuated by the lever. G During the revolution of the wheel G the lever G is held depressed, so

that the cam j is held out of the way of the arm D until the reproducer has completed its travel across the record, whereupon, the

lever G rising, the cam j is elevated, thereby raising the reproducer and causing it to shift back to its starting position with the arm D rising against the yielding stop j".

The frame which supports the phonograph and the winding-motor may be of any suitable construction. Preferably it comprises integral bottom-members p and standards p, the standards being surmounted by the usual top plate 11 whichsupports'the lever G may main portionof the mechanism proper and in which the record-actuating shaft D is journaled. v p

The mode of operation may be briefly summarized thus: ,The motor E is pre aratorily operated to give the spring of the spring-driven train of thephonograph-adesired tension, -which tension is greater than is actually required to turn the record until the reproducer has fully traversed it, therebyassuring adequate power anda desired rate of rotation of the record at all times. The motor circuit may be closed in any-suitable way to effect the initial Winding of the phonograph-spring. The wheel F is pre aratorily adjusted, so'that after the spring 0 the pho- 1 .nograph has been preparatorily wound the notch f receives theiu'g f? of the contactthe motor-circuit left normally open. As-

.suming the friction-brake, which constitutes a portion of the governor D and is ,well=nn-- derstood in the 'art, to be pre aratorily set to control the rate of rotation o the record and] shifter F, whereby the wheel-F is locked and assuming the spring of the spring-motor of the phonogra h to be properly wound, the

' lie depressed, as by means of a coin, thereby to, withdraw the stopand permit the record to As soon asthe to cause the record begins to turn the wheel L t driven from the spring-motor, begins to turn also and depresses the lever'G thereby tilting the front end of the reproducer J down wardly and allowing the reproducer to drop until the stylus engages the record. As the wheel G nears the end of its revolution the cam g operates the lever G and withdraws the member F from the position shown in Fig; 8 to theposition shown in. Fig. 9, the

springF operating at the same time to draw. the free end of the member F forwardly, so

that the shoulder f will be in position to engage the shoulder f upon the return move; stud g releases the lever G, the spring a rement of the member F Whenthe cams turns the member F to approximate y its normal position, thereby forcing the member In the movement of the member F the wheel F is unlocked, and immediately the winding- F outwardly and closing the motor-circuit.

wheel E is set in operation the pawl F begins to turn'the wheel F.

flange f alongside the lug f 3 in readiness to prevent return of the member F until the wheel F has completed a revolution. In the The firsteffectofthe movement of the Wheel F is to bring the 1 first movement of the wheel F also the cam I F" engages the projection F on the member F there by moving the freeend of said member rearwardly and effecting its release from the member F After this release of the member F from the position shown in Fig. 10' the stop F dro s to the position shown in Fig. 8,- where it rorms a stop for the member F It will be seen, therefore, that when the Wheel F completes its rotation the member F'isfree to swing inwardly until the lug has fully entered the recess f Returning now to theaction which occurred when the wheel G started to rotate, it should be stated that theefl'ect of de ressing the lever G was awl, to interlock with the supporting disk, has its lower end engaged by the inclined surface of the cam F whenthe' member F returns under the actionof its sprin ber F outwardly, and when the. cam F forces .the free. end of the; member F rear wardly the stop F drops oif thee am F and,:

occupies the position shown in Fig. 9. Thus it wi lbe seen that the stop 'F is held in an elevated position; preventing therotation of to force the pontact-actuating .mem-

the record until the electric motor has started to rewind the spring of the s ring-motor, so that said spring is prevented from running down. It should be added, is apparent fromFi 3, any excessive. winding of the spring the spring-motor would be relieved by a rotation of the record, the stops d yield- .ing'to pass the stop H, thereby preventing breakage. Moreover, the yielding of the stops (1 breaks the shock which otherwise would occur when the record is stopped at the end of the operation.

It will be obvious that many changes in details of construction within the spirit of my inventionmay be made. Hence no undue .limitation should be understood from the vention in its widest application, regardless of the particular use to which the invention 1 may be put.

As is Well understood, electric currents of the same nominal voltage vary at different plants throughout the country, sothatan electric motor cannot be used without great limitations for the direct actuation of a phonograph the number of the rotations of the record in which must be subject to very little variation. Furthermorefthe provision of means for quickly and readily winding the spring-motor of a phonograph of the type herein shown and for insuring the proper degree of winding-is regarded as of great importance,
