BELFORD G. ROYAL, OF LONDON, ENGLAND, ASSIGNOR TO THE GRAMO- PIIONE AND TYPEWRITER, LIMITED, OF LONDON, ENGLAND, A COR- PORATION.

COIN-OPERATED TALKING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 706,203, dated August 5, 1902.

Application tiled February 7, 1901. Serial No. 46,399. (No model.)

To @ZZ whom zz': may concern:

Be it known that I, BELFORD G. ROYAL, a citizen of the United States, residing at London, England, have invented certain new and useful Improvements in Coin-Operated Talking-Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying` drawings, forming a part of this specification.

My invention has relation to mechanism for controlling the operation of a talking-machine, subject to the deposit of a coin, and is particularly adapted to that class commer cially known as the gramophone, although it may be applied to other machines of a similar character.

The main object of my invention is to provide simple and eiicective mechanism for controlling the operation of gramophones and the like, subject to the deposit of a suitable coin, which mechanism is not liable to derangement from ordinary usage and which can be readily applied to the ordinary construction ot spring-motor, such as are used for running machines of this kind.

The invention consists in providing means for locking the record-support and motor normally against rotation and in providing mechanisrn controlled by the deposit of a coin for releasing this locking means and permitting the motor to operate until the record-support has made a certain number of revolutions sufficient toallow of the complete reproduction of the record employed and then automatically stop the motor and record-support and reset the starting mechanism in position to be again actuated by the coin-controlled mechanism.

My invention further consists in the construction, combination, and arrangement of the various parts, such as hereinafter fully set forth, and particularly pointed out in the claims made hereto.

Referring to the accompanying drawings, in which similar numerals ot' reference are used to indicate similar parts, Figure 1 is a sectional elevation through the motor-casing of a gramophon'e, showing the initial position of the parts and the turn-table locked against rotation. Fig. 2 is a view similar to Fig. 1,

with the exception that a portion of the motor-casing is broken away and the coin-operating mechanism is shown in the position it assumes when the push-bar is depressed and the motor and turn-table ready for operation. Fig. 3 is a detail perspective View of the coinreceiving device. Fig. 4 is a front elevation of the outer section ot the coin-receiver, illustrating the manner in which the coin is held in such receptacle. Fig. 5 is a similar' view to Eig. 4, showing the coin partially ejected through the action of the push-bar.

The spring-motor used in connection with this invention may be any of the improved styles, and therefore need not be described in detail. The driving-spindle 1 is mounted in suitable bearings provided in the frame 2 and is geared, by means of the usual gears, to the spring-propelled shaft, which is not illustrated. A suitable governor, as 3, is provided for regulating and maintaining an even speed for the motor. A wooden or other suitable casing, such as et, is provided for covering the motor mechanism. The upper end of the driving-spindle l projects through the casing 4E and carries the turn-table 5, which forms a support for the record 6. The said turn-table is mounted on the spindle 1, so as to revolve therewith, and the record Gis secured on said table in thisinstance by means ofa hand-nut 7.

Rigidly secured on the driving-spindle 1 is a worm 8, adapted to mesh with a worm-gear 9, journaled in a supporting-frame 10. Rigidly secured to the worm-gear 9 is a disk 10, having a cut-away portion 12 formed thereon, and directlyin front of the said cut-away portion is a projecting pin 13, which is adapted'to engage the teeth of a star-wheel 14. This star-wheel 14 is mounted on a stub-shaft 15, journaled in the standard 10 on a horizontal line parallel with the axis of the worinwheel 9, so that as the Worm-wheel makes one complete revolution the star-wheel will be moved the distance between two of its notches, or one-ninth of a revolution in this instance.

Pivoted tothe lower part of the standard 10, below the star-wheel, is a bell-crank lever 16, having one arm 17 extending upwardly in front of the face of the star-wheel and in the path of a projecting pin 18, which is carried by the said star-wheel a short distance from its center. The lower horizontally-disposed arm 19 of the bell-crank lever extends through an opening 20, provided in the casing4 of the motor. Pivoted to the arm 19 at about its central portion is a rod 21, which extends up through the casing 4 and passes through a bearing-plate 22, secured to the top of the casing, and enters a conntersink or aperture provided on the under side of the turn-table 5 when the mechanism is in the posit-ion shown in Fig. l and the machine is inoperative. Adjacent to the upper end of the arm 17 is a projecting pin 23, and bearing against this pin is the upper end ot' a pivoted.

l lpawl 24, the said pawl being pivoted to the standard 10, as illustrated in Figs. 1 and 2. A coiled spring 25, secured at its lower end to the arm 19 of the bell-crank, is provided, having an eye formed in its intermediateA portion, which is secured to a pin 26, carried by the standard 10, and beyond this eye is a straight portion which bears against the upper edge of the pawl 24, so as to keep the said pawl in contact with the pin 23. On the end of the arm 19 of the bell-crank lever is pivoted a pawl 27, which has a small spring 28 secured to its upper portion for the purpose of normally holding it up in the position illustrated in Fig. l of the drawings.

The coin-receiver 29 is made in two sections, as 30 and 3l, secured togethervby suitable screws, as 32, and the said receptacle is secured to the machine-casing by means of the screws 33, which pass through the aperlu res- 34 in both sections of the receiver. The upper portion of said receiver is provided with a slot 35, and directly below the said slot is a swinging tumbler 36, pivoted at 37 to the side wallsl ot' the casing, the said tumbler having a projeciing beveled lip 38 formed on its upper inner edge, which normally rests by gravity in a correspondingly-shaped recess 39, formed in the receiver-casing. The lower end on the tumbler 36 is also provided with a projection 40, which when the tumbler is tilted b v the entrance of a coin through the slot 35 enters a recess 4l formed in the rear wall of the coin-receiver, thus forminga trap and preventing the entrance of the coin to the lower portion of the receiver until after the tumbler 36 has lreturned by gravity to its normal position and closed the upper portion of said receiver. The object of this construction is to prevent the insertion of a wire or other instrument for fraudulently manipulating the starting mechanism of the machine.

After the coin is released by the tumbler 36 it falls onto the inclined wall 42 and is held in the position illustrated in Figs. 1 and 4 of the drawings by the springs 43, which are bent to conform somewhat to the periphery of the coin, as shown most clearly vin Figs. 4 and 5 of the drawings. In .front of the partition 42 is formed a cylindrical barrel or casing 43, into which fits a sliding push-rod 44. The end of the cylindrical barrel 43 is open and is screw-threaded for the reception of a plug 45. bar and the plug 45 is interposed a coiled spring 46, which normally tends to keep the push-bar in the position shown in Fig. 1 of the drawings. The push-rod 44 is provided with a recess in which is pivotally mounted a detent 47, the lower end of which extends beyond the surface of the push-barand passes throughaslot48. (Mostclearlyillustrated in Fig.4 of the drawings.) The upper arm 49 of the detent 47 is provided with a small spring 50 on its under side,which normally tends to keep the projecting end of the detent in the position shown in Fig. 1 of the drawings. The inner wall of the receiver is provided with a slot 51, which registers with the slot 48, and the pawl 27, carried by the arm 19 of the bellcrank lever, bears against the outside face of this slot, as illustrated in Fig. 1 of the drawings.

When the push-bar 34 is depressed and a coin has been inserted into the receiver and is held in position therein by the springs 43, the said pivoted detent will come in contact with the upper edge of the coin and be thrown outwardly into the position illustrated in Fig. 2 of the drawings, its lower end projecting a slight distance through the slot 51, and on the downward movement of the said push-bar will come in contact with the pawl 27 and throw down the arm 19 of the bell-crank lever and at the same time eject the coin from its holder. As the arm 19 is thrown downwardly Between the lower end of the pushroo into the position illustrated in Fig. 2 of the drawings the rod 2l will be withdrawn from engagement with the aperture in the turn-table, thereby unlocking the said table and allowing the same to rotate through the medium of its connection with the spring-motor mechanism. Simultaneously with this operation the upper arm 17 of the bell-crank and its pin 23 move inwardly and the spring-pressed pawl engages the said pin 23 and holds the bellcrank in this position, as shown in Fig. 2, and the motor operates.

In operation as the spindle 1 is driven motion is transmitted by the worm 8 to the wormwheel 9, and through the medium of the pin 13 the star-wheel is moved one notch for every revolution of the worm-gear, and the pin 18, carried by the starwheel 14, is gradually moved in the direction of the arrow until it comes in contact with the arm 17 of the bellcrank, when it then throws the said arm 17- slightly forward and at the same time comes in contact with the edge of the pawl, thereby raising the said pawl, and as the said pin 18 continues its movement the arm 17 is released and is thrown back in the position illustrated in Fig. 1 through the action of the coil-spring 25, and immediately after the releasing of the arm 17 the pawl 24 is released and ilies back against the pin 23, as shown in Fig. 1 of the drawings. Simultaneously with the release loq IIO

ofthe arm 17 from the pin 18 and the flying back of said arm the lower arm 1S) is thrown upwardly, and the rod 21, which is pivoted thereto, is moved upwardly until its upper end comes in contact with the lower side of the turn-table 5 and enters the aperture or countersink provided therein, and thereby immediately stopping the machine. The various parts are now reset ready to be actuated as soon as the proper coin is deposited in the receiver.
