UNITED STATES PATENT OFFICE.

FRANK J. BERNARD, OF JERSEY CITY, ASSIGNORJBY DIRECT AND MESNE ASSIGNMENTS, TO THE AMERICAN MUSIC BOX COMPANY, OF WEST NEW YORK, NEW JERSEY.

MUSIC-BOX REGULATOR.

SPECIFICATION forming part of Letters Patent No. 554,906, dated February 18, 1896.

Application filed May 9, 1895. Serial No. 5 18,785- (No model.)

T at 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 consists in furnishing a music-box with a cheap and efiect- IO ive regulator.

The invention consists in forming from a thin piece of metal a regulator for a musicbox.

Figure 1 is the regulator before folding.

Fig. 2 is a side view of Fig. 1. Fig. 3 shows the regulator when folded. Fig. 4: shows the expansion of the wings when in use, and Fig. 5, shows the regulator as applied to a musicbox to govern the speed of the several gears and pinions.

A in Figs. 1 and 2 represents a thin spring metallic strip or other suitable material.

B B, Fig. 1, represent recesses formed by cutting the metal at b b and bending the cut part B down, while the metal B is pressed in an opposite direction, which forms a central recess B, Fig. 2, through which the wormarbor C is passed, as shown in Fig. 3. The strips A are then formed like the letter N by 0 following the metal on lines a: a, one end being folded to the right and the other folded to the left, forming wings A A and a center section A, as shown in Figs. 3 and 4':- The ends of these wings extend beyond the center sectionA", as shown in Fig. 3, which catch the air when rotated in the line of the arrow, causing them to spread, as shown in Fig. 4.

E, E, F and I, Fig. 5, are gears and pinions (forming the driving mechanism of a music-box) mounted on the arbors E F and I, which are driven by the springs H secured to the case F by screws H for rotating the pressure-rolls K and L and note-sheet N.

J, Fig. 5, is a section of the music-box frame having jewel-cap J held in place by the screw. This frame supports the arbor C, which is provided with the worm-threads C, having the usual spring check-lever D held in place by the flanges D D. To this worm-arbor I secure my improved regulator, which governs the speed of the gears and pinions by the overlapping wings catching the air more or less during the unwinding of the spring from first to last.

While I have shown and described the wings A as approximately parallel to the central section, I do not limit the construction to this form, as the wings may be parallel to the central section.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

A regulator-vane comprising a straight central section and the parallel right and left wings extending beyond the central section, said Vane formed of an integral sheet of metal, as and for the purpose described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 29th day of April, 1895.

FRANK J. BERNARD.
