MUSIC-BOX.

SPECIFICATION forming part of Letters Patent No. 572,950, dated December 15, 1896.

Serial No. 548,784. (No model.)

To all whom it may concern.-

Be it known that I, FRANK J. BERNARD, a citizen of the United States, and a resident of Jersey City, county of Hudson, and State of New Jersey, have invented a new and useful Improvement in Music-Boxes, of which the following is a specification.

The object of this invention is to provide a musical instrument with any interchangeable tune-sheet which can be used to operate a hammer.

The invention consists in a spring-operated mechanism for feeding a perforated notesheet, a pivoted trip, a spring-hammer, reeds, and a tension-roll.

Figure 1 is a side view of the improved musical instrument. Fig. 2 is a partial top View of Fig. 1, and Fig. 3 is an end view of the reeds and supports.

A in the several figures represents a supporting-frame having stanchions A, A A, and A for supporting the various parts of the mechanism in their proper places. The stanchions A A and A are provided with arms A, A A A and A, which hold the various arbors and reeds, as shown in Fig. 1.

13, Fig. 1, is a case secured to or an integral part of the primary gearB for the spring (not shown) forming the motive power to drive the chain of gears and pinions B, which feed the perforated music-sheet G, the speed being governed by the regulator O, which is fastened to the Worm C. The gears and pinions are mounted on the arbors B as shown in Fig. 1.

D D, Figs. 1 and 2, are series of trips pivoted on the shaft 13 and provided with a spring-tongue D, held in place by the rivets D and having on their outer ends a ball D The vertical section of the lever D is provided with an inclined plane D, which provents the lever from catching in the noteholes G of the sheet G. It also forms an easy surface for the sheet to run over and gradually forces the lever D down after the point D has been raised through an opening G of the sheet.

D is a stop-rod which prevents the head D of the lever D from going too far through the note-holes G of the sheet G. The stoprod D is provided with a rubber sleeve D", Fig. 2, which prevents noise.

F, Fig. 2, is a cylinder or drum having flanges F. On this cylinder the perforated sheet-music G is wound previous to operating the machine. This cylinder is mounted on the arbor A which is supported in the open bearings A as shown in Fig. 1.

F is a pressure or idle drum which holds the music-sheet down and assists in maintaining an even tension on the sheet in order to hold the lever D in a proper place and pre vent the ball-hammer D from vibrating only when the head D of the lever is permitted to rise through the note-holes G.

F is a rewinding-cylinder to which one en d of the 1nusicsheet is attached before the instrument is set in motion.

It is supported on the arbor l3 and is held down against the rubber feed-roll II by spring A", and as the cylinder Iills up permits it to rise in the slot A.

The rubber roll II is mounted on the drum II, which is operated by the gearwork.

E in the several figures are tube-reeds mounted on the stanchion cross-bar A and held in place by the screws A. These tubereeds are made of steel or other metal and vary in size and length to produce the proper sound or notes in one or more octaves.

The operation is as follows: The instrument is set in motion, which causes the perforated sheet G to move, and as the several note-holes G, which are perforated in line with the levers D, reach the lever-head D it is forced through the holes G by the spring D caus ing the lever to swing on the pivot 13 and allows the spring-hammer D to strike the reed-tube E, causing the proper sound. The sheet then, which is steadily advancing,
