MUSIC-BOX ATTACHMENT FOR LOCKS.

SPESE ICATION forming part of Letters Patent No. 293,696, dated Fe *inary 5, M84

Application filed XovemhcriS, 1553. (X0 model.)

To all whom, it may (Jo/warn.-

Be it known that I, J ACOB SCHMID, of New Brunswick, in the county of Hiddlesex and State of New Jersey, have invented certain new and useful Improvements in Music-Box Attachments to Clocks, of which the following'is a specification.

This invention has reference to an improved music-box attachment to clocks, so that whenever the clock has struck the full hours the music-box plays a piece; and the invention consists of a music-box arranged on a sounding-board of the clock-ease,which is provided with screened escapeopenings at both sides. The n1usic-box is connected by an intermediate lever mechanism with a hammer that is lifted by suitable means on the arbor of the hour-hand and dropped by a trip-lever of the striking mechanism as soon as the full hour has struck, so that the intermediate lever mechanism is struck by the hammer and releases a locking-pawl of the cylinder-barrel of the music-box and admits the starting of the same. A small guard-plate at the end of a spring covers the perforation on the end disk of the cylinder-barrel as soon as the pawl is withdrawn by the intermediate lever mechan ism and secures the proper starting of the cylinder-barrel until the piece is played, upon which the pawl returns into its normal position.

Inthe accompanying drawings, Figurel represents a front elevation of a clock with my improved music-box attachment, partly in section. Fig. 2 is a vertical transverse section of the same on line a a", Fig. 1. Figs. 3 and 4 are respectively a detail front view and v a vertical transverse section on line i/ y, Fig.

3, of the music-box and its connection with the mechanism for starting the same. Fig. 5 is a rear elevation of the clock-move1nent, showing the hammer for starting the musicbox. Fig. 6 is a horizontal section of the clockcase on liney y, Fig. 1; and Fig. '7 a detail vcrtical transverse section on line k 7;, Fig. 5.

Similar letters of reference indicate corre sponding parts.

A in the drawings represents a clock move ment of any approved construction, and B a clock-case inelosing the same.

In the lower part of the cloclecase is arranged a music-box, C, which is attached to a sountlingboard, D, that is screwed to the rear wall of the clock-case 13. The side walls of the case are provided with screened openings Z) I) for the escape of the sounds. A lockingpawl, a, which is generally used in musicboxes, takes byapin at its end into a hole, a, of a disk, A, on the shaft of the cylinder-barrel of the music-box, and permits the starting of the same by the actuating-spring whenever it is withdrawn from the hole a. The mainspring of the music-box is wound up from time to time by a cord, G,which passes through an opening of the side wall of the clock-case to the outside. A thin steel guard-plate, a is attached to the forward end of a spring, a that is secured by its rear end to the baseplate of the music-box. The guard-plate a is arranged sidcwise of the disk A, and interposed between the pin of the pawl a. and the hole aat the moment when the pawl a is with drawn from the hole a of the disk, so as to prevent thereby the re-entering of the pin of the pawl by the action of its spring into the hole a, so as to secure the reliable starting of the cylinder-barrel whenever the pawl is released from the disk A. The opposite end ol, the pawl a is connected by wire, (7, with one arm of a bell-crank, d, which latter forms by a rest plate, ll, at its other arm, contact with a trip-rod, c, that is vertically guided in eyes 0 of the clock-case. The rod 0 receives a downward pressure by a spiral sprin 0, that is interposed between the eye 0 and collar 0 on the trip-rod c. I

The trip-rod c is extended upward to the rear part of the ClOCl-l11OVC11lllt A and placed in the path of a hammer, E, the rod E of which is pivoted to the rear frame of the clockmovement and lifted by a disk, E, that is keyed to the rear end of the arbor F of the hour-hand, said disk engaging by a pin, f, of a pivoted and spring-actuated trip, f, a wire fork, J, of the hammer-rod 11, so that by the turning of the arbor of the hour-hand the hammer E is gradually raised, as shown in Fig. 5, As soon as the full hour has been struck by the striking mechanism a trip-arm, g, on the pawl of the notched wheel ofthe striking meclr anism strikes by the hopping of said pawl against the pivoted trip f, so that its pinf is IOO released from the fork f of the hammer-rod, and the hammer dropped with considerable force on the trip-rod e, as shown in dotted lines in Fig. 5. The blow of the hammer is transmitted by the trip-rod 0 against the tension of its spring a to the bell-crank d, which, by the wire connection (I, withdraws the pawl a from the opening a. of the disk of the cylinder-barrel, which is instantly covered by the guard-plate a so that the'cylinderbarrel is started by the mainspring of the music-box, and thereby a tune played, after the striking mechanism of the clock-movement has finished the striking of the{ full hour. The disk E continues to rotate with the arbor of the hourhand until in the course of the next hour it raises the hammer again to its full height, from which it is dropped again by the release of the trip f, owing to the engagement with the trip-arm g, and so on every hour.

' \Vhen a piece of music has been played by the box and the hole a of the disk A comes around again to the pin of the pawl a, the latter quickly re-engages the hole a and brings thereby the cylinder-barrel to a stop. In this manner a very neat and attractive music-box attachment for clocks is obtained, which is very reliable in its action, and which is heard to advantage all over the room, owing to the arrangement of the sounding-board back of the music'boX and the escape-openings for the sounds in the case of the clock.

Having thus described my invention, I claim as new, and desire to secure by Letters Pat ent 1. The combination of a clockmovement having a trip-arm on the pawl of the striking mechanism, a trip mechanism on the arbor of the hour-hand, a trip-hammer that is raised by the same and dropped after the full hour is struck, a musio-box arranged below the clockmovement, and an intermediate mechanism that extends from a point in the path of the hammer to the locking device of the musicbox, so that whenever the clock has struck the full hour the locking device is released and the musiebor. set in motion, substantially as set forth.

2. The combination, with a clock-case having screened side openings, of a music-box placed on a sounding-board attached to the case, means connecting the starting device of the music-box with the clock-movement, a trip hammer pivoted to the rear frame of the move ment, a trip device on the arbor of the hourhand, and a trip-arm of the pawl of the striking mechanism, whereby the music-box is started after each full hour has struck, substantially as specified. I o. The combination of a music-box provided with a locking-pawl and a spring-.actu ated guard-plate sidewise of the disk of the cylinder-barrel, an intermediate mechanism connecting the pawl with the clock-movement, a trip-hammer pivoted to the frame of the clock-movement and adapted to actuate the intermediate mechanism, a trip mechanism secured to the arbor of the hour-hand and adapted to engage the hammer-rod, and the trip-arm on the pawl of the striking mechanism, that releases the trip mechanism of the arbor from the hammer-rod as soon as a full hour has struck, substantially as set forth.

4. The combination of a music-box, A, having a locking-pawl, a, and a spring-acted guard-plate, a, sidewise of the disk A of the cylinder-barrel, a connecting-rod, (1, bolt crank d, a vertically-guided and springcushioned trip-rod c, a trip-hammer, E, pivoted to the fame of the clock-movement and having a fork, f, a disk, E on the arbor of the hour-hand, said disk having a spring-acted trip, f, and pin f, and a trip-arm, g, on the pawl of the striking mechanism of the clock, substantially as described. 1

In testimony that I claim the foregoing as my invention I have signed my name in.presence of two subscribing witnesses.

JACOB SCHMID.
