'panying drawings, forming a part of the same.

This invention relates to automatically operated phonographs, and more particularly to means for raising the reproducer from the record and for returning the parts to normal or starting position.

In accordance with the present invention, the return echanism of the phonograph is actuated by a motor other than that by which the phonograph is given its F reproducing movements, such additional motor being preferably an electric motor. By providing such additional motor for operating the return mechanism,

fthemotorby which the'phonograp h is given its reproduping movements is relieved of the work of actuating the return mechanism and a much quicker return may obtained than would otherwise be possible with such motors 'as are ordinarily used for operating the phone graph.

The invention has been made in connection with and in some of its features is especially adapted for use with phonographs provided with means for automatically re-winding the motor by which the phonograph is given its reproducing movements, and more particidarlyphonographs of this class in which the phonograph is actuated by a spring motor which is automatically re-wound by an electric motor. When the present invention is applied to such phonograph the automatic return mechanism may be actuated by the electric rewinding motor, the spring motor being thus relieved of the work of actuating the return mechanism. The invention is not howeverfto be limited in all its features to a construction in which the return mechanism is actuated by the rewinding motor, since obviously a special motor might be provided for actuating the return. mechanism, and when such special motor is provided the invention might be applied to a phonograph not having a re-winding motor as w%ll as to 6ne having a re-winding motor.

A full understanding of the invention can best be given by a detailed description of a preferred construction embodying the various features thereof, and-such a description will now be given in connection with the accompanying drawings which show the invention ,as applied toa spring motor actuated phonograph.

In said drawings. Figure l is an elevation. Fig} 2 is a plan of a spring motor actuated phonograph of known construction provided with an automatic return mechanism and with re-winding means constructed in accordance with the present invention. Fig. 3 is a View of parts of the operating mechanism looking from the back of Figs. 1 and 2. Fig. 4 is a view, partly in section on line x:c of Fig. 3. Fig. 5 is a view, partly in section on lineyy of Fig. 2, looking toward the right. Fig; 6 is a view of parts shown in Fig. 5; but in a different position. Fig. 7 is an enlarged view of parts oithe automatic return mechanism, looking toward the lettin Figs. 1 and 2. Fig. 8 is a detail view of the friction coupling interposed between the electric motor and the spring motor, the friction spring of st: ch

coupling being removed.

Referring first to Figs. 1 and 2, a represents the bed of-th'e phonograph, b is the reproducer arm which is carried by a sleeve 1) movable on the guide-bar b and the free end of which reproducer arm rests on the supporting rail a.

0 represents the feed-screw, and c the feed nut carried by the sleeve b and engaging the under side of the feed screw for causing the reproducing movement of the reproducer arm. i

11 represents the mandrel, the shaft of which is con nected with the shaft of the feed screw 0 by gears c. The mandrel and feed screw shafts are mounted in bearings 2, 3 and 4. The mandrel shaft is driven by a belt (1 running on a pulley d on said shaft and a pulley e on a shaft of the train of gears e of the spring motor 6 by which the phonograph is operated in reproducing a record. These parts are or usual and well known con struction, and do not require further description.

Secured to the reproducer arm I) (see especially Fig. 7) is a bracket arm b which carries an arbor f upon which an eccentric disk 9 is revoluble. The arbor f also supports an adjustable sleeve f clamped thereto by the set screw shown inFigs. 2 and 7 the ofiice of which sleeve will be hereinafter described. The eccentric or cam disk 9- is provided with a notched hub g, and has secured to its face a weight 6, and its periphery is formed with a notch or low portion 7, with a toothed portion 8 beyond the low portion 7 and extending to a high portion, with a tail rib 9 beyond the toothed portion, and with a portion 10 which is smooth. Pivotally connected to the bracket arm 5 is a latch h having a other side of the pivot from the tooth 11 for engaging a cam rod or arm 13 adjustable longitudinally on a support 14 secured to the bed a of the phonograph. TA return feed screw i is mounted. in bearings 15 upon thebed oithe phonograph. This. screw shaft preferably has a spiral groove oi coarse pitch compared with the thread of the feed, screw cand is provided with teeth between the convolutions of the groove for a portion of its length. The shaft of the return feed screw carries fast thereon a sprocket i.

1 represents the shaft from an electric motor, having at its upper end a worm l meshing with a gear m mounted free to rotate upon a horizontally extending shaft m mounted in bearings in the sides of a casing is, said worm gear m having a spur gear m formed or secured to rotate with it. The shaft m is driven by the rotation of the gear m, through a slip coupling which will permit the gear to slip on the shaft when a certain resistance is offered to the rotation of the shaft. A suitable form of friction coupling for this purpose is shown. As shown, a collar 18 is mounted fast on the shaft m at one side of the gears m and m and at the other side of said gears is a collar 17 also fast on the shaft, while between the collar 17 and the gears is a notched flanged sleeve 0 held against rotation relatively to the shaft m by a pin 0 and pressed against the face of the gear m by a spring 19 one end of which bears against the collar 17 and the other end against the flange of the sleeve 0*. (Figs. 3 and 8). The shaft m is continued by means of a coupling shown in Figs. 1 and 3, and terminates in a pinion meshing with a gear through which the spring motor e may be rewound.

A shaft n is mounted above the shaft m in bearings 16. Fast on this shaft is a gear m meshing with the gear m also fast on this shaft n is a sprocket n a chain to passing around the sprocket n and to and around the sprocket t" on the shaft of the return feed screw for rotating said shaft. The shaft 11 also has fast thereon a pinion n meshing with a gear 0 mounted upon an arbor 0 which is secured in a lug of the casing k. A cam disk s of con ducting material is mounted to rotate with the gear 04 and is insulated from the gear 0 and the arbor 0 by be ing mounted on an insulating disk 1' secured to the gear 0. A spring contact arm 1. for engaging the periphery of the cam disk s is secured by a binding-post clamp t to an insulating post s fast to a post- It rising from the top plate is of the casing It. A contact spring 1' which constantly bears against the face of the cam disk 8 is also secured by a binding-post clamp 1" to the insulatingpost 8. To the binding-post clamps t and r are connected wires 20 and 21 respectively of the circuit to the electric motor, so that in the operation of the machine when the contact arm 1, engages the cam disk s the circuit will be closed for operating the motor.

The contact arm t is normally .held out of contact with "the cam disk s by means of a rocker arm r pivoted at 22 to a bracket arm 10*. One end of this rocker arm is provided with an insulating blockgv' adapted to move beneath the contact arm 1. when the latter has been raised by the high point of the cam disk 5, and the rocker arm is under tension of aspring 23 which tends to swing the rocker arm on its pivot to move the block 11 toward and beneath the end of the contact arm. The

. other end of the rocker arm is provided with a foot up the spring motor e.

the spring arm t, in which position the electric circuit is broken and the electric motor not running. As shown in Figs. 1 and 2, the extreme adyan'ce movement of the reproducer arm and arbor f have brought the end of the sleeve f in contact with the foot-piece r and the rocker-arm 1' has been thereby swung on its pivot to remove the insulating-block 1; from beneath the end of the spring arm t, allowing the same to drop into contact with the periphery of the cam disk s so as to complete the electric circuit through the wire 20, binding post clamp 6, arm t, cam disk s, contact spring r binding post clamp 1" and wire 21, thereby starting the electric motor. The insulating block r is then held against the side of the arm t by the action ofthe spring 23 until the arm t is again raised by the cam disk 3 to permit the block if to again move beneath the arm t. The electric motor being thus started, the rotation of the shaft Z and worm-wheel'l drives the gears m and m and the shaft m is frictionally driven through the friction'coupling formed by the collar 17 and 18, the sleeve c and the spring 19 thereby winding Simultaneously the gear m causes the rotation of the gear m and the shaft n, which through the sprocket n, the chain 10 and the sprocket i drives the return feed screw 1', and the shaft 11 through the pinion n also rotates the gear of and the cam disk s, these parts being so timed and proportioned that the cam disk is not given a complete rotation until the return-feed screw has been given a rotation more than sufficient to effect the raising of the reproducer armand its complete return movement'and lowering again to its operative position.

\Vhen the return feed screw 1' begins to rotate the teeth thereof engage and mesh with the teeth 8 of the eccentric disk 9 (see Fig. 7) and the disk is thereby rotated to cause successive portions of its toothed cam periphery to engage the return feed screw thereby raising the bracket arm b and reproduce-r arm b to raise the reproducer from the record and move the feed nut from the feed screw 0 until the teeth 8 have paid out and the tail rib 9 of this eccentric disk has settl d into the groove of the return feed screw i. The tooth ll of the latch h then drops into the notch of the hub g and holds the eccentric disk against further turning, and the disk, the arm I)? and the reproducer arm b are then by the continued rotation of the return feed screw given a rethe portion 10 of its cam periphery in engagement with the shaft, whereby the bracket arm b and the reproducer arm are gradually lowered until the reproduce'r is returned to operative position and the feed nut is again" in engagementwith the feed screw 0. The turning of the disk 9 will continue until its per-i'phery cleansthe return feed screw, after which, during any further rotation of the return feed screw and during the next reproducing movement of the reproducer arm, the disk will be held by the weight 6 in position with its low portion 7 opposite the return feed screw and with the shoulder formed by the firstv of its teeth 8 bearing against the return teed screw ready to be engaged by the teeth of the return feed screw when the latter is rotated for the next return movement. feed screw continues until the end of the contact arm t is raised by the can. disk 8 to permit the block 11 of the rocker arma to move under the end of the contact arm and until the high point of the cam disk has then moved beyond and out of contact with the contact arm, thereby breaking the circuit and stopping the electric motor. To insure the full return movement of the reproducer arm, the amount of rotation given to the return feed screw is preferably, and as before pointed out, more than sufiicient to effect the elevation, return and lowering of the reproducer arm with thelongest record which the machine is adapted to reproduce. The return feed screw will thus continue to rotate after the reproducer arm has been returned and lowered; and to prevent the eccentric disk g, which then rests with the -first of its teeth 8 bearing against the return teed screw,

from being turned by such further rotation of the return feed screw, the portion of the return teed screw against which the disk 9 then rests is circumferentially smooth, the gear teeth of the return feed screw extending only for a part of the length of the screw from the other end thereof.

If the spring motor e is allowed to continue in operation after the return of the reproducer arm and the feed nut to operative position, the phonograph will be again actuated thereby for again reproducing the rec- 0rd, the electric motor meanwhile remaining at rest until the iepi'oducer arm nears the end of its reproducing movement, at which time the sleeve f will again engage the loot piece 1; to swing the rocker arm 12 to carry the black 71 from under the contact arm t and permit the contact arm to spring into contact with the periphery of the cam disk 5, thereby again closing the circuit for causing the electric motor to operate to rewind the spring motor and to rotate the returnleed screw for again returning the reproducer arm to its initial or starting position. Evidently, however, suitable means may be provided for stopping the operation oi the spring motor before the return movement of the reproducer arm has been completed, and when such means is provided the entire mechanism will remain at rest after the return movement of the reproduccl. arm has been completed and until the spring motor is again put in operation, whereupon the reproducing and return movements of the phonograph and the rewinding of the spring motor will again be effected in order and repeated until the spring motor is again stopped.

By adjustment of the sleeve f and the cam rod 13, the mechanism maybe adaptedior records of varying length so that the reproducing devices shall operate only over the length of the actual record, thus avoiding waste-oi time and unnecessary movement otthe parts. I

To insure tall fewindingei the spring motor with The rotation of the returnthe longest record which the machine is adapted to reproduce, the amount of rotation given to the Worm gear m at each operation of the electric motor will preferably be more thansuflicient to rewind the spring motor to the tension to which it was wound beiorethe commencement of the reproducing movement, and the iriction coupling. between the worm gear and the rewinding shaft m is provided for the purpose of permitting continued movement of the worm gear after the spring motor has been fully rewound, the resistanceto the rotation of the shalt at being suflicient. to cause the parts of the coupling to slip.

It will be seen that with the construction shown, the return movement of the reciprocating part oi the phonograph, that is the reproducer arm in the construction shown, is effected entirely by the power of the electric motor and does not add at all to the work to be performed by and cannot efiect the operation of the spring motor.

It will be understood also that features of the invention may be employed independently of other features thereof, and that the invention or features" thereof may be applied to other forms of phonographs from that shown.
