-Referringto the drawings, 0. represents .the mandrel or record carrier, b the reproducer armmounted to slide on the rod 0, d the feed screw, and e the food not of a phonea h of common construction.

The rocking lever v is pivoted at 122- and is under tension of a spring 123 which tends to swing the lever on its pivot to move the block if toward and beneath the contact arm t. The other end of the rocki arm is provided with. a foot piece 1/ whic lies in the reproducer arm of theiphonograph the foot piece 1; when the rocking arm is in position t lying in sition to be engaged by t as save 1' as t e reproducer arm approaches the'end of its re reducing movement. During tion of the phonographthe rocking arm 1: is in its normal position with its insulating block 0 beneath the. end of the contact ring 1!. As the reproducer arm'approaches e end of ,its reproducing movement, the sleeve f comes into e ement wit the foot piece o and forces t e ever against the tension of its spring so as to move the insulating block '0' from beneath the end of the contact spring 6 as shown in Fi ,1 permit- .ting the latter to engage the peri hery of the cam disk- 8 as shown in Fig. 8. commit to the electric motor being thereby closed, the motor will start to operate and will continue to operate until'the gear 0 and.cam disk s have made one rotation, at the end of which time the contact spring t will drop from the art of the cam disk" and ain rest on .t e insulating'block o, the lever v aving in the meantime been returned by its lspring to itsnorm'al position;

and the worm wheel m and between the return screw shaft and the'worm wheel are such that the cam disk is not iven a com plete rotation until the worm w eel ha been rotated more than suflicient to insurethe reby means of a rocking The' contact carried by the 'with its insulating block beneath the end of. the-contact s ii the mproducing operaconnections between the cam disk 8 t 25 and of the phono raph.

is swung in the ot er direction to retract the winding of the spring motor and the return feed screw has been given a rotation more than sufficient to effect the raising of t e rsproduccr arm and its complete return ova,- ment and to lower it again to its normal position.

The operation of the phonograph by the motor A is controlled by means of a sto ping and starting device consisting preferab y of a brake formed by a spring plate l-(g) acting on the periphery of a disk 11 on the governor shaft of the motor. The brake spring 10 is moved into and out of operative position in a direction tan ent-ial to the periphery of the disk 11, and or this pur ose it 18 preferably and as shown carried b T a reciprocating plate 12 shown as ivota ly mounted ona stud 13 extending ownward from the base plate 14 of the phonograph (see Fig. 6). When the plate, 12 is swung in one.direction,

the brake spring will be carried into engagement with the periphery of the disk 11, as shown in Fig. 1 and in full lines in Fig. 2, thereby stopping the operation of the motor When the plate 12 brake sprin and release the disk, the brake s rin will st move while in contact with t disk and thereby impart a starting move- I ment' thereto. Any chancepf the motor and the mechanism driven thereby failing tostart'when released will thus be avoids The plate or support 12 might be'actu'ated by any suitable means for hand or automatic operation. As shown, it i is oscillated by means of a spring 26 acting through a vertical shaft 16 and an arm 15 carried by said sh'aft, said arm having a pin 17 extending into a cam slot 18 in the plate 12. The shaft 40 16 is turned against the tensionof the spring 26 for causing the brake spring 10 to move into operative position by the returnmovement of the reproduoer arm, and the turning of the shaft in the opposite direction for re tracting the brake spring is controlled by the check actuated mechanism. For ar-f pose, in the construction shown, the sh .16 carries at its upper end a short arm '20 jecting into the return movement path'of. a finger 21 carried ,by the reproducer armb. On the forward movement of the-reproduce? arm the finger 21 travelsbeneath the arm 20,v but on, the return movement of the reproducer s1tion,. as r arm we "it is in its elevated shown in dotted lines in Fig; 2, t e finger .21

is raised so that the arm 2Q extends into; the

path of its returning movement." The shaft, v

roekqdfto the position shown i 111 i 'Figflunder runs the eml'oi a a t t 1 dis by which engagement of the arm 22 with the shoulder 25 the shaft 16 is held against turning under tension of the spring 26. The pressure of the end of the late arm 22 against the shoulder 25 should not be so wet as to interfere with the movement of t to beam 24 under the influence of the check as hereinafter described; and in order that suflicient force may be exerted on the supporting plate 12 to effect a sufficiently forcible retraction'of the brake without causing too great a pressure of the latch arm against the shoulder 25 in the construction shown, the latch arm is made considerably longer thanthe arm -15. The

arm 15 and the latch arm thus form a lever t which is engaged by the shoulder 25 at a point fart-her om its fulcrum than its conmotion with the plate 12. The other arm of the rocking beam 24 carries a coin tray or receptacle 27 in position beneath the lowe nqnd of a coin chute 28,-and the beam is normally held in. the position shown in F' 3 by means of an adjustable Wei ht 29, sue weight beingsufiicient to hol the beam normally in the position shown, but to be overbalanced by the coin or check delivered on the tra When in this position the shoulder 25 ism position to engage the end of the latch arm 22 and hold the arm and the shaftlfi against movement by the s ring 26. The beam 25 is shown as pivotal mounted in a support 30 extending upwar from a base 3 and the end of the coin chute 28 is suppoted by a bracket 32 extending 11 Ward fromthe base plate 31- being clamps toysa1d-braeket by means'ol a strap 33.

erate under the influence of the motor spring, the mandrel a rotating to rotate the record cylinder carried thereby and the feed screw d rotating to feed the reproducer carrier longitudinal y of the mandrel to carry the reproducer over the rec d. The reproducing operation of the phonographwill continue until, as the reproducer arm or carrier reaches the end of its reproducing movement the lever '01 is moved to carry the insulating block c" from beneath the end of the contact spring t, thereby closing the circuit to the electric motor E. The electric motor will then operate to re wind the spring motor and to rotate the return feed screw i, thereby causing the reproducer arm or carrier to be raised and returned to itsnormal or starting position, as hereinbefore explained. During the return movement of the re reducer carrier, the'finger 21 will engage t 0 arm 20 and move the 'same from the position shown in dotted lines to that Sl'lOWIl'lIl full lines in Fig. 2, thereby turning the shaft 16 against the tension of the spring 26 and returning thelatch arm 22 to position to be engaged again by the shoulder 25 on the beam-24, in which position it will then be held by the shoulder 25, the coin having fallen from the inclined tray 27, and the position-ofthe beam be: again "determined b' the weight 29. By such rocking of the aim t 16 the arm 15 and thereby the a 12 will s own by full lines in Fig. 2, and by such return movement of the plate 12 the brake spring 10 will be carried again into contact with the periphery of the disk 11, thereby stopping t e rotatlon of said disk and the opparts driven tinue tooperate until, when the cam disk 8 has made a com lete rotation, thespring contact t drops "om-the end ofth'e point of the cam disk thereby opening t e motor circuit and coming to rest on the msulating block '0. The operational the electric motor will then cease and the various operative parts of'the entire mqchine will again be in theirnormal position of rest, the spring of the spring motor having been rewound in readiness for another 0 oration.
