AUTOMATIC FEED AND RETURN MECHANISM FOR PHONOGRAPHS.

SPECIFICATION forming part of Letters Patent No. 489,519, dated January 10, 1893.

Application filed November 20. 1890. Serial No. 372,019. (No model.)

To all whom it may concern.-

Be it known that I, MARCUS O. ANTHONY, a citizen of the United States, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Automatic Feed and Return Mechanisms for Phonographs, of which the following is a specification.

The object of my invention is to provide an automatic coin actuated feed and return mechanism for phonographs, whereby the machine may be entirely inclosed and protected from injury either from carelessness ignorance or rough handling, by thoughtless or I 5 evil disposed persons. It is especially intended for that class of exhibition machines which are placed in public places to reproduce popular music or declamations forthe amusement of those who may drop acoin in a slot in the case inclosing the machine. In instruments of this class now in use, a push rod or lever projects through the case which is connected to the sensitive mechanism within. It is requisite to operate this rod or lever after the coin is dropped in, in order to set the machine in motion. I have found by experience that the handling of this rod or lever by careless or inexperienced persons deranges the sensitive mechanism of the phonograph, frequentlyin- 3o jures the phonogram and causes a drawling sound at the commencement, and ending, of the piece upon the phonogram. All of these defects are remedied by my invention,which I will now proceed to describe in detail, in con- 3 5 nection with the accompanying drawings, af-

ter which I willparticularly refer to and point out its novel features in the claims.

Referringto the drawings in which like parts are indicated by similar reference letters and numerals wherever they occur throughout the various views. Figure 1. is a plan view of a phonograph detached from its inclosingcase,

'and provided with my improvements. Fig. 2. is a front elevation of the attachment.

5 Fig. 3. is a transverse vertical section taken through line 0c, 00, of Fig. 2,1ookingto the left, with the parts in position they occupy when the reproducer carriage or spectacle frame is coupled to the lead screw, which is formed upon the shaftof thephonogram carrier. Fig.

4 is a similar view with the carriage or spectaclc frame disconnected from the lead screw and coupled to the retracting screw. Fig. 5

is a similar View in the same plane with the parts inposition shown in Fig. 3. Fig. 6 is a detail view in front elevation of the device for coupling the carriage to the retracting screw. Fig. 7. is a detail view in vertical section through line y, y, of Fig. 2, looking to the left.

In Fig. 1 A represents the plate upon which the body of the well known Edison phonograph is mounted, the phonogram cylinder B, lead screw B, traveling carriage O, the coupling armO, rocking spectacle frame 0 which carries the reproducer, and the mechanism for actuating, them as well as the bearings or supports in which they are mounted, are well known and need not therefore be specifically described.

All of my improvements are mounted upon or supported in a standard or frame which is secured by a pivot screw' upon the cabinet top in front of the phonograph.

The frame in which my improvements are mounted consists of base bar D, end uprights, d, d, and intermediate uprights d 61 and d, all of which are preferably east in a single piece.

The return screw E, which has a much greater pitch than the lead screw, is mounted on centers 6, e, in the end uprights d, d. The screw shaft E, is revolved by a belt 6 passing over pulley 6 which is secured upon the shaft near one end, and over a pulley driven by the motor which operates the phonograph; I

the belt is kept tight by a coiled spring 6 one end of which is secured to the frame D, and the opposite end by a screw to the cabinet top. (Not shown.)

F is a frame swung upon pivot pins (1 which are secured to the uprights d, 01 and pass through the arms of the frame to allow the frame a limited longitudinal movement. The frame is counterpoised bya weighted lever armf, which is fulcrumed at,f upon 5 the upright d the inner end of this lever bears upon the under side of the free end of the frame, and the opposite end of the lever is provided with a weight f To the front end of the rocking arm 0 [00 which carries the reproducer, is detachably secured an arm G, which extends transversely across the frame F; the frame F, is slot-ted longitudinally, the screw shanks of the movable stops F, pass through this slot and have tightening screws underneath. Against one of these stops the arm G, strikes as it is carried in one direction by the lead screw B, and against the other one when carried in the opposite direction by the retracting screw E; the frame F, is carried a short distance by the arm G, as it strikes either stop, and by this means the frame C, is automatically coupled to the lead screw and disconnected from the retracting screw when the frame is carried to the left by the arm G, and automatically coupled to the retracting screw and disconnected from the lead screw when the frame F, is carried to the right. This coupling is accomplished by the depression of the free end of the frame in one case and the elevation of it in the other. It is understood of course that the elevation of the frame disconnects the reproducer from the phonogram, and its depression connects the reproducer and phonogram.

The free end of the frame F, is supported in its lower position upon the upper end of the upright 61 and in its upper position upon the upper end of the bar H, which is pivoted upon the front edge of the upright LP, a foot f projects down from the frame F, to rest upon the top of the pivoted bar H. In the lower position the rocking frame (J, 0, C is uncoupled from the retracting screw and coupled to the lead screw, the reproducer is also in contact with the phonogram. In the upper position the rocking frame is coupled to the retracting screw and uncoupled from the lead screw and phouogram. The arm II, is drawn and held in its vertical position by a coiled spring h, which pulls it againsta stop h.

Upon the reduced right hand end of the screw shaft E, is secured a disk 6 and loosely fitted upon this reduced end is a cam I, in proximity to the disk, a pin 6 projects inward from the side of disk a and a similar pin 2', projects from the adjacent side of the cam, both pins are arranged the same dis tance from the axis of the screw shaft E so that when the cam is pushed in the direction of the disk it is revolved with the disk by the pin 6 striking the pin i. Depending down from the end of the frame D along side of the cam I, is a rigid arm (1, which has an offset above the lowest part of the cam when the frame F, is in its lowest position.

Pivoted to one side of the arm G, is a jay, J, which extends down below the retracting screw E, and has a hooked arm to pass under the screw, the upper side of this arm is curved and spirally inclined to engage the screw threads and couple the arm G, to the retracting screw E, when the frame F, is thrown to the upper position. The upper horizontal arm j, of the jay is a spring and is perforated to pass over a pin j, which projects from the arm G. The purpose of this arrangement is to hold the jay firmly in place and to permit it to be thrown from under the screw when it is desired to raise the rocking frame C and arm G, which may be done by drawing out the spring arm j, until it is disconnected from the pin j, when the jay may be swung around upon its pivotj.

In the position shown in Figs. 2 and 3 the frame F, is depressed, the jay J, disconnected from the retracting screw the arm 0, coupled to the lead screw and the reproducer bearing upon the phonogram. The machine is thus in the position it occupies when reproducing the piece upon the phonogram. Now as the spectacle frame G with arm G, connected to it moves to the right, the arm G, will strike the stop F, and carry the frame F, to the right until the arm d strikes the cam I, and carries it in the direction of the disk e, by the same movement of the frame F, the upper end of the pivoted bar II, is pressed to the right by the foot f Now as the disk revolves the cam I, under the offset of the arm d, the free end of the frame is elevated, disconnecting the arm O, from the lead screw and coupling the jay with the retracting screw, so soon as the foot f, is elevated above the top of the bar H, the spring It, draws it back to its vertical position under the foot the frame F, is thus held in its upright position until it is moved in the opposite direction which is done by the arm G, carrying it to the left, a sufficient distance to pull the foot off of the bar 1-1, when the frame again drops to the position shown in Figs. 2 and 3. At the same time a spring 11', which is coiled around the shaft E, between the cam I, and the disk e, presses the cam away and disconnects the pins e, and 2'. i p

I will now describe the means by which the machine is automatically set in motion, and automatically stopped: From the frame F, a legf extends downwardly opposite the standard d, which projects up from the base D, a contact spring L, is secured to one side of this leg, but insulated from it by the plate of fiber Z, or other insulating material. The spring extends around the under side of this leg and is inclined upwardly and outwardly from it. In the upper slotted end of the standard (1*, is journaled a leverM, upon the inner end of which is formed a bar m, which overbalances the long arm m, of the lever, which carries and holds the bar 071, against the standard d", and out of contact with the spring L. The long arm of the lever M, is slotted to receive but not pass a coin, which is dropped into a chute N, the outer end of which extends through the case or cabinet and the inner end of which terminates above and registers with the slot in the lever arm so that when the coin is dropped into the chute it will fall into the slot in the arm on, depress the lever, and bring its inner end in contact with the spring L, thus closing the circuit through the frame of the attachment. The electric wire 1, connects to the spring L, and the wire 2, connects to the upright d the piuf, projects out from the leg f to stop the lever in nearly a horizontal position until the frame F, is moved to the left a sufficient distance to draw the pin from over the bar m, of the lever when the weight of the coin throws the long end of the lever down the coin will roll off into a receptacle in the cabinet, when the lever will be returned to its normal position to receive another coin. The movement of the frame to the left also draws the foot f off from the top of the pivoted bar H, when the free end of the frame drops down and brings the base of the spring L, upon a spring 0. This again closes the circuit which remains closed until the arm G, is carried to the right a sufficient distance to engage the stop F, and carry the frame along with it until the cam I, engages with the leg and elevates the frame F, and breaks the circuit: The contact surfaces are preferably tipped with platinum to prevent injury from sparking when contact is made or broken. From the foregoing it will be seen that so soon as the piece upon the phonogram has been given off the frame F, is elevated, the circuitbroken, causing the mechanism to stop, the spectacle frame 0 uncoupled from the lead-screw and coupled to the retracting screw, ready to be returned, and the piece again given off by the introduction of another coin into the chute. The stops F, F, are set to correspond to the length of the piece upon the phonogram. To prevent jar when the frame F, is carried to the left by the arm G, I interpose a coiled spring f around the pin (1 between the arm f, and the upright 61 I do not limit myself to the exact construction and arrangement of the parts shown that it is evident that many mere mechanical changes may be made to accomplish the same result. I would therefore have it understood that I shall consider such mere mechanical changes as within the spirit and scope of my invention.
