COIN-OPERATED PHONOGRAPH.

SPECIFICATION forming part of Letters Patent No. 494,778, dated April 4, 1893.

Application filed July 3l, 1890.

To a/ZZ whom, it may concern.-

Be it known that I, ELLswonTn E. FLORA, a citizen ofthe United States, residing at Chicago,in the county of Cook and State of Illinois, have invented anew and usefullmprovement in Coin-Operated Phonographs, of which the following is a specification.

My invention relates to an improvement in the class of attachments for use upon the phonograph to canse it., by the insertion of a coin or token, (intended to represent the price for the privilege of using the instrument,) into a coin-chute, in turn to close the circuit, and thus induce operation of the phonograph, then release the coin, and, linally, elect the return of the carriage to its initial position.

My improvement, While it relates, generally, to the entire coin-actuated mechanism, relates especially to the device for effecting, automatically, the return to its initial position of the phonograph-carriage; my main object being, in that connection, to provide a simply constructed, readily and reliably operating, and durable returning apparatus.

Further objects are to afford generally improved means for producing the automatic operation of a phonograph by the insertion of a coin or circuit-closing token into a slot.

In the accompanying drawings-Figure l is a plan view of a phonograph provided with my improvement; Fig. 2, a section taken at the line 2 of Fig. l, viewed in the direction of the arrow,and showing the construction of the coin-chute and circuit controlling mechanism thereon; Fig. 3, a section taken at the line 3 of Fig. 2 and viewed in the direction of the arrow. Figs. 4 and 5 are sections taken, respectively, on the line -iin Fig. 3, the former showing the parts of the chut-e in their relative positions with a coin inserted, and the latter showing their subsequent relative positions. Fig. 6 is a section taken on the line 6 of Fig. l and viewed in the direction of the arrow; Fig. 7, a bottom plan View of a detail; Fig. S, a section taken at the line S of Fig. l and viewed in the direction of the arrow; Fig. 9, a view in broken front elevation of the automatic returning mechanism; Fig. l0, a section taken at the line lO of Fig. 9, viewed in the direction of the arrow and enlarged; and Fig. il, a perspective view of a broken `lar o. r'duced between the leverk 'u and spring s', or

portion of the endless band of the returning mechanism supporting the dog.

A is the metallic coin-chute supported, preferably as shown, on the shaft r of aphonograph, which shaft carries the phonographcarriage involving the sliding sleeve r snrrounding the shaft r and carrying the stylusdevice B and the finger q, which engages at its free end with the thread on the screwshaftp carrying the cylinder p.

To support the chute A, I provide, to extend from its rear side, a split collar, o, the parts of which are secured together around the shaft fr, by screws t and t', (the latter fastening the chute and collar together) whereby it may be readily loosened to permit the chute to be adjusted on the shaft nearer to or farther from the end thereof, toward which the carriage travels in the operation of the phonograph, depending on the extent of travel desired for the carriage.

Near the lower end of the upper sideot' the chute, which should be open along a portion of its under side to permit the inserted coin to drop out when released in the manner hereinafter described,is an opening, n, into which projects a flat metal spring, s, extending from the lower end of the chute, from which it is insulated, being secured in place by a binding-post, as. Another springs', projects laterally at a right-angle to the spring s, being secured by the same means that fasten the lastnamed spring and bent over the side of the chute beyond which it projects, as shown. A metal lever, o, fulcrn med between its extremities to the side of the chute A at which the spring s projects, extends at one end into contact with the spring s', being controlled, to tend normally to make such contact, by a spring, to. The opposite upper end of the lever o is provided with a fingen/U', bent to extend, under the chute, parallel with the shaft r into the pat-h of the sleeve r. 4

The circuit runs as follows: B y the wires, fr?, from the battery (not shown) respectively to the binding-post .at on the chute, and the terminal u, of the phonograph-motor (not disclosed); the opposite terminal being connected by a wire, so, with the screw ton the col- Thus, as will be seen,if contact be prothe spring sbe electrically connected with the chute A, the circuit will be closed, thereby setting the motor in operation, and, through the medium of the gearing illustrated, driving the screw-shaft p, the rotation of which produces the travel of the carriage in the usual and well known manner in phonographs.

When the carriage is in its normal initial position, as represented in Fig. 1, the end of the sleeve fr on the shaft 7', nearest the collar o, bears against the linger t" of the lever n, thereby forcing the lower, contact-end, of the latter inward, and maintaining it out of contact with the spring s until the sleeve r is moved to advance on its route and permit the spring w, by thus freeing it, to operate to force the lower end of the lever into contact with the spring s. Therefore, the carriage being, normally, in` the initial position referred to, obviously the circuit is normally open, owing to the separation of the spring s and lever o, and of the spring s at its free end, from the chute A.

By inserting a coin, C, (Fig. 4) into the chute A, it slides down the latter until it makes contact with the spring s, thereby producing electrical connection between that spring and the chute, being prevented from falling out of the open under side of the chute by the normally inward projecting laterally enlarged end o2 of the lever o so that when the coin is inserted, it Acloses the circuit and operates the phonograph. When the sleeve a", in the operation of the instrument, has moved away, on the route of the carriage, sufficiently far to remove its end from the linger o of the lever o, thus freeing the latter, the springw, controlling it1 is permitted to act to force the lower end o2 outward, thereby deprivingfthe coin of its support and allowing it to drop out (into a suitable receptacle, not shown). While this dropping out of the coin breaks the electrical connection between the chute A `and spring s, it does not open the circuit, since before that connection is'broken, another is made between the lever o and spring s', which latter continues the operation of the instrument until the carriage is returned to. its initial position, wherein it effects opening of the circuit and thus stoppage of the motor, by the bearing of the sleeve r against the finger o.

The gear-mechanism referred to between the motor and screw-shaft ,fp may be of the well-known orany suitable construction, though inasmuch as it is desirable that the coin-operating attachment constituting the' subject of my improvement, shall be applicable to the instrument Withoutl in any, at`

pulley device D, through the Inediti m ofl which the governor-shaft l is geared to the screwshaft p. To that end,l make use of the stops m2, in the form ot' screws (Figs. 6 and 7) which are commonly inserted transversely into opposite sides of the hub extending upward from the pulley D, and provide on opposite sides of the pulley m, pins, m', to extend vertically downward from opposite sides of the center of the pulley, being far enough apart to embrace the said hub between them, thus permitting the pulley m to be adjusted by placing it on the hub, causing the pins m to embrace the latter, and turning it until stopped -by contact of the pins with the stops m2. The tapering bearing m3, supported in the bracket m4, engages the upper side of the pulley m.

The returning-mechanism for the carriage, hereinbefore referred to, involves the following construction: E and Eare two guide-pulleys, supported in suitable bearings, la and la', extending from opposite ends of a lever, F; which should be provided, longitudinally,with a guide-slot, t. This bar may be supported on the instrument in any desired or suitable bracket to be secured to the base of the instrument. As shown, (Fig. 9) I fasten the bar F, by screws, y, to the frame of the instrument supporting the shafts pand r. An endless band, G, is supported around the peripheries of the horizontally disposed pulleys E and E', and carries, rigidly secured to it, a dog, G', having its upper edge inclined downward from a backward-inclined stop, h. The under side of the pulley El is provided with a beveled gear-wheel, g, to be engaged by a beveled pinion, g', on a slceve,f, surrounding a portion of the length of a rod, H, loosely supported, in the manner hereinafter described, in the bearing la, through which it passes, and toward its opposite end, in a bearing, k2, having a set-screw, 7c3, on a bar, F', forming an extension of the bar F, to which it is secured, and propped by leg, z. I also provide, in the bar F', a horizontally disposed set-screw, e', (Fig. l) to bear against the frame of the machine and serve for springing the bar outward and inward, with reference to the frame, to adjust it and thereby tighten or loosen the belt e2, connecting the pulley m, with a vertically disposed pulley e on the adjacent end of the sleeve f,thereby to rotate the latter on its supporting-rod H and thus drive the beveled pinion g. Thepinion g tends normally to engage with the gear g by a spring, d, extending froin the bearing k against the under side of the adjacent portion of the longitudinally adjustable rod H, the spring being adj ustable to bear with greater or less pressure against the rod, by a set-screw, d (Fig. 9). The meshing of the pinion g and gear gis prevented, however, during the travel of the phonograph-carriage from its initial position, bya tongue, I, on the stylus-deviceB resting upon the rod I-I and thus bearing down upon it, thereby springing it toward its free end to manner, as by forming the cross-head of a IOO maintain the two gears outof mesh, the opening c (Fig. 10) in the bearing it for the passage of the rod, being elongated to permit this transverse movement of the rod H. When, in the travel of the carriage, it passes beyond the end of the rod H, the latter is free to be raised byits controlling spring d, thereby producing engagement ot the pinion g with the gear-wheel g. The tongue I should be separably connected with the end b of the stylusdevice B, being secured in position by a setscrew, a, in order that in respect thereto also, the original instrument need not be altered in the application of my improvement.

The entire operation of the device is as follows: On inserting a coin Cinto the chute A, it produces, in the manner already described, electrical connection between the springs and chute, and, by the consequent closing of the circuit, actuates the motor to drive the screw' shaft p and thus produce the travel of the carriage in the common manner. TWhile the carriage is moving forward, it maintains the -pinion g out of mesh with the gear g by the bearing of its tongue I against the rod H, so that although the pinion rotates constantly while Ythe circuit remains closed, (since the pulley fm, geared to the pulley e on the sleeve f carrying the pinion must rotate, being secured to the pulley D) it performs no work until the tongue I clears the rod H. The extent of the portion of the rod H upon which the tongue bears may be increased or diminished, by sliding it in the proper direction, to increase or diminish the extent of forward travel of the carriage. In moving, the sleeve a" is withdrawn from its bearing effect against the finger n of the lever 'za-thereby permitting the spring c2 to act to remove the lower end of the lever to the contact-spring s', and, by thus removing the support from the coin, permitting it to drop out of the opening in the back ot the chute A, but, as already eX- piained, without opening the circuit. When the tongue I has passed the1end of the rod H, the spring CZ raises the latter, producing engagement ot' the pinion g with the geanwheel g, rotating it and, through it, the pulley E. This causes the endless band G to travel, whereby the dog G is eventually brought against the tongue I and raises it to turn the stylus-device B, and through it the sleeve r', back on the shaft fr, and thus also raise the finger q out of engagement with the thread on the shaft p, freeing-the carriage to enable it to be returned without obstruction. The return is produced by the continued travel ot' the band G, causing the dog G', at its stop h, to push the carriage at the tongue I along ahead ci' the dog, until the sleeve fr strikes the collar o, which stops the carriage, the dog clearing the tongue bypassing under it, which it does without material obstruction therefrom, owing to the inclination of the stop h. As the sleeve fr reaches the end of its returnroute, it bears against the fingern and thereby breaks the contact between the lever 'v and spring s', thus opening the circuit, stopping the lnpon of t-he driving-mechanism, and placing the parts into their relative positions illustrated, in which they are adapted to kbe again atuated by an inserted coin.

Obviously my improved circuit-controllin g mechanism may be used with a phonograph independently of my particular, or any, carriage-returning mechanism; and my automatically operating returning mechanism may be employed with advantage on the phonograph with any circuit-closing device, whether coin-operated or not.

The broad principle involved in my improvementis that of employing an endless carrier to operate, when the carriage reaches a predetermined point, to return it. Hence I do not Wish to be understood as limiting my invention to the exact means shown and described for producing automatically the return of the carriage, as these may be variously changed without thereby departing from the spirit of my invention.
