EL. L. GUENDBT & F. J. BERNARD. NCTE PLATE ECE MECHANICAL MUSICAL INSTRUMENTS. No. 577,839.

Patented Mar. 2, 1897,

UNITED STATES EMILE L. CUENDET, OF NEIV YORK,

PATENT OEEICE.

N. Y., AND FRANK J. BERNARD, OF

IIOBOKEN, NEIV JERSEY.

SPECIFICATION forming part of Letters Patent No. 577,839, dated March 2, 1897.

.Application iiled June 20, 1896.

To all whom t may concern:

Be it knownthat we, EMILE L. CUENDET, a citizen of Switzerland, residing at New York, in the county and State of New York, and FRANK J. BERNARD, a citizen of the United States, residing at Hoboken, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Note-Plates for Mechanical Musical Instruments, of which the following is a specification.

This invention relates to an improved construction of a note plate or disk for mechanical musical instruments, and has for its object to improve the construction of its note pins or lugs.

In the accompanying drawings, Figure l is a plan of a portion of a note-plate embodying our invention. Fig. 2 is a section on line 2 2, Fig. l; Fig. 3, a section on line 3 3, Fig. 4i; and Fig. 4t, a detail top view of a portion of a note-plate, showing one of the note pins or lugs.

The letter A represents the circular body of a slotted sheet-metal note-plate adapted to be rotated around its axis and provided with the reed-actuating pins, as usual.

In order to impart rotary motion to the disk A, we provide it at a short distance from its periphery with a circular concentric rack composed of a number of equally-spaced einbossed teeth a, engaged by a pinion b.

Serial No. 596,250. (No model.)

The note pins or lugs c are punched out of the body of the disk and are curled to forni a closed eye, the end c of which abuts against the body of the lug. Immediately back of this closed eye a boss d is struck out of the plate A, which contacts with the body of the lug and tends to prevent it from bending. That is to say, the pressure borne by the front of the lug c while playing the instrument will have a tendency to bend such lug backward. This tendency is, however, resisted by the boss d, which forms an abutment for the rear of the lug. Moreover, as the free end c/ of the lug contacts with the body thereof the entire body of the lug is braced and a very high degree of strength is obtained.

Vhat we claim is- A note-plate provided with a curled lug, the end of which abuts against the body of the lug, and with a boss that contacts with the back of suchlug, substantially as specified.

Signed at New York, in the county of New York and State of New York, this 16th day of June, A. D. 1896.
