A TTORNE).

hub H, provided with a longitudinal slot II. A pin I, fitting in the bore of the hub H, has its outer end tapered, and is provided with a stud I, that can move in the slot H as the pin I slides in and out of said hub.- A toothed wheel J, resting against the side of the motorwheel and mounted to turn on the slotted tubular hub H, is provided with an annular stepped cam J, against which the stud I rests. A curved flat pawl-lever K is pivoted at K to the side of the wheel D, and is provided near one end on its inner edge with the shoulder K that can act on the ends of the teeth of the toothed wheel J. At the same end the pawl-lever is provided on its outer edge with the bevel K on which the curved cam-spur L can act that projects from the tune-changing lever L, pivoted at L on the top of the base-plate and having its outer end engaged by the forked lower end of the lever L pivoted to the standard a.

A helical spring M has one end attached to the upper end of the pawl-lever K and the other end attached to the side of the wheel D, and said spring draws the upper end of the pawl-lever against a stop-pin M, projecting from the side of the wheel D, whereby the beveled end of the pawl-lever is thrown out ward toward the periphery of the wheel D, which is its normal position. A pinion N, engaging the wheel I), operates the automatic check N,which forms no part of this invention.

A lever 0, having a curved arm O,is pivoted to the standard a andis provided at its upper end with a handle and is to be known as the tune-selecting lever. A helical spring P has one end secured to said lever above its pivot, and theother end is secured to the standard a, which spring serves to hold said lever 0 against a stop-pin P on the standard a, this being the normal position of the said lever, as shown in Fig. 5. A pawl-arm Q is pivoted at Q to the lever O and has one end secured to a helical spring P the opposite end of which is secured to the standard a", and which spring holds the pawl-arm raised and against the stop-pin Q on the lever O, as is also shown in Fig. 5.

An annular ridge R, provided with a recess R, is formed on the back of the wheel D, as shown in Fig. 4.

At that end of the base-plate opposite the one at which the spring-motor is located two short standards 1) project upward from said base-plate, and in the same the bearing-pin S is mounted to slide lengthwise and parallel with the base-plate, one end of said pin S being tapered. A helical spring S surrounds said bearing-pin S between one of the stand ards b and a cross-pin or stud S on said pin S, which spring presses the said bearing-pin S in the direction of the arrow at, Fig. 8. A cam T, provided with a hook T, is pivoted at T to the outer surface of one standard I), and is provided with a handle T for turning it. The cam T has a segmental slot U,through which the end of the bearing-pin S passes,

and from the projecting end of the bearingpin a stud U projects, which rests on the edge of the cam. A lever V is pivoted at V to the under side of the base-plate below the standards 17, and is provided at one end with an arm V projecting toward the end of the base-plate. Said end of the lever is pressed against a stop screw or pin V by a helical spring V attached to said lever and to the base-plate. The opposite end of the lever V is pivoted to one end of a rod W, extending along the under side of the baseplate to a slot d in the baseplate, through which slot the upwardly-extending arm \V of said rod projects, and the upper end of said arm is secured to a slide X on the upper surface of the base-plate, which slide has an arm X, provided with a spur X that can pass into a recess Y in the outer sides of the drum E, as shown in dotted lines in Fig. 1 and in full lines in Fig. 7. The slide X is provided at its outer end with a beveled flange d, on which the beveled lower end 6 of the starting and stopping lever e, pivoted on the standard a, can act.

The tune-indicating pointer g is pivoted at g to the inclined plate h, fastened on the standards I), and the stud S on the bearing pin S projects through the slot 1' of the plate It and rests against the pointer 9 below the pivot of the same. As the spring S exerts a pressure in the direction of the arrow 00, Fig. 8, it tends to bring the pointer g to the numeral 1 on the plate h. A spring is, secured to the under side of the plate h, bears against a pin Z, projecting above the pivot g from the pointer g through a slot m of said plate 9.

At the ends of the cylinder-slot in the baseplate two standards 11 are attached to the baseplate at the edge of said slot, and from the top and bottom ends of said standards the pins 0 project toward each other, which pins 0 prevent the pins on the pin-cylinder B from coming in contact with the teeth of the comb A while inserting the cylinder, as the circular end plates of the cylinder rest against the pins 0 and thus guide the cylinder downward and toward the rear and from the ends of the teeth.

The operation is as follows: When there is no cylinder in the boX, the cam T is in the position shown in dotted lines in Fig. 9 and the bearing-pin S is withdrawn and is in the position shown in dotted lines in Fig. 8. A cylinder is grasped by the buttons B and placed into the slot-in the base-plate in such a manner that the pin O on the motor-wheel D, which pin C is now in its lowest position, passes in the notch B of the cylinder. The cam T is then swung into the position shown in full lines in Fig. 9, permitting the spring S to press the pin S in the direction of the arrowcc, Fig. 8, and said pin under the action of the spring presses the cylinder in like direction and against the pin 1, which is pushed into its hub until its stud I is pressed firmly against the cam track J on the toothed wheel J.

To start the music-box, the lever e is moved from the position shown in Fig. 7 to the left, so as to cause its beveled lower end to act on the inclined or beveled flange (Z of the slide X and to move said slide in the direction of the arrow Figs. 3 and 13, whereby the spur or prong X on the arm X of said slide is removed from the recess Y in the drum E, permitting the spring in the drum to turn the gearing, and by means of the same the pin-cylinder, as the pin (1 on the motor-wheel l), which is operated from said spring, is within the notch of the cylinder. By the movement of the rod \Y, connected with the slide X, in the direction of the arrow X the arm on the end of the lever V is moved outward in the inverse direction of the arrow .11 and over the prong of the hook T, as shown in Fig. 9, as said hook is now in its lowest position. The cam T is thereby locked in place and it is impossible to remove the cylinder.

\Vhen the tune has been played-that is, when the cylinder has made one turn and the lever 6 has been pushed back into the position shown in Fig. 7, so that its lower end clears the beveled flange (Z of the slide X the spur or prong X can passinto the recess Y in the end of the cylinder E, thus permitting the slide X to move in the inverse direction of the arrow a under the action of the spring Y. The pin i on the slide X now engages the flier G, and the mechanism is stopped and the spring-drum is locked by the spur or prong X passing into the recess Y. The end V of the lever V is withdrawn from the hook T of the cam T, permitting the same to be turned so as to withdraw the pin S, whereby the cylinder is released and can be lifted out of the box. In case the tune played is tobe changed for each rotation of the cylinder, the tune-changing lever L is properly adjusted. As the wheel I) rotates, the beveled edge K" of the cam K comes in contact with the end of the spur L and is pushed toward the center of the wheel I)-that is, from the position shown in dotted lines in Fig. 5 to the position shown in full lines-causing the shoulder or ot't'set K to engage a tooth of the tooth ed wheel J, whereby the latteris turned on the hub II, and the pin I is moved lengthwise a distance sufficient to shift the cylinderlengthwise the distance required for a change of tune. Af ter the pivoted pawl-lever K has turned the toothed wheel J the required distance it clears the spur L and is brought back into its original position by the spring M. It at any time when the cylinder is at rest the box is to be adjusted to play any desired tune, the tune-selecting lever 0 is brought from the position shown in Fig. 5 into the position shown in Fig. 6, so as to cause the pawl-arm Q to turn the wheel J the distance of one tooth. This is repeated until the cylinder has been shifted lengthwise the requisite distance. W hen ever the lever O is released, the

springs P and P throw it and its pawl-arm Q back to the normal position.

\Vhen the cylinder is locked in position, as it can be only after completing a tune, the recess R in the ridge R will bein the position relatively to the fixed parts shown in Fig. 4', and as the arm 0 of the lever can pass through said recess R the lever 0 can be swung forward, as described, to shift; the cylinder. At any other time except when the cylinder is locked this is not possible, as the recess R will then not be in the proper position, and the end of the arm 0 strikes the ridge R and is then checked and cannot be swung forward sufficiently to shift the cylindcr. As the cylinder is shifted lengthwise to change the tune, the pin Sis shifted correspondingly, and this causes a corresponding movement of the pointer g, which at alltimes points to the number of the tune being played.
