ALBERT F. NORRIS, OF BOSTON, MASSACHUSETTS.

PIANO-PEDAL SUPPORT AND BEARING.

SPECIFICATION forming part of Letters Patent No. 644,446, dated February 2'7, 1900.

Application filed April '7, 1899. Serial No. 712,113. (No model.)

To all whom it may concern:

Be it known that I, ALBERT F. NORRIS, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Piano-Pedal Sup,- ports and Bearings, of which the followingis a specification.

This in vention has relation to bearings and supports for piano-pedals, and has for its ob ject to provide a mounting which shall render the pedals easy to adjust and easily inserted or removed, as well as one which is simple and strong and of inexpensive construction.

To this end the invention consists in the improvements which I shall now proceed to describe and claim.

Of the accompanying drawings, Figure 1 represents a plan view of a bracket and pedals embodying my invention. Fig. 2 represents a section on the line 2 2 of Fig. 1.

The same reference characters indicate the same parts in both the figures.

Referring to the drawings, a is a solid cast base having screw-holes a o for the reception of screws by which the base may be attached to a suitable support forming part of the piano. Integrally formed with the base a are upright lugs or standards a a, bet ween which the pedals b I) (here shown as three in number) are hung. The immediate supports for the pedals are pivots c c, loosely fitted in in by set-screws cl d, screwing through the tops of the standards and abutting the stems of the pivots. The pivots have conical ends fitting in conical sockets in the sides ofthe pedals and are two in number for each pedal. It will be noted that the inner standards of the two outer pedals and the two standards of the middle pedal are cast together, making two lugs or standards for supporting four pivots, this being done for the sake of convenience and strength. The pivots which hang the middle pedal are set back of those which hang the two end pedals, thus giving convenient access to the projecting heels or rear ends of all the pivots. The lengths of said pivots are made such that they terminate short of the adjacent pedal when the pedals are properly centered, and the position and dimensions of the standards a a are regulated so as to leave a space in the vicinity of the heel of each pivot, which allows convenient access thereto.

Heretofore in pedal-supports wherein independent pivots have been employed it has been customary to screw the pivots through side supporting-lugs and lock them with checknuts. My present construction, however, is less costly than this and it involves a quicker and easier adjustment of the pedals and their bearings and a firmer locking of the pivots. The pivots are preferably made to slide easily in their sockets, so as to be capable of being moved by a persons fingers. The only tool then required for the adjustment, removal,

or insertion of the pedals is a wrench to turn the set-screws d d. The heads of the latter may conveniently be squared and slightly tapered, as shown in the drawings, so as to fit an ordinary tuning-hammer, such as is used to turn the tuning-pins of the piano-strings.

To change the adjustment of a pedal, the set-screw on either or both of its pivots is loosened, the pivot moved the required distance, and the set-screw then retightened, locking the pivot firmly in place. The whole operation need occupy but the fraction of a minute. Any pedal may be centeredthat is, haveits lateral position shifted-by loosen ing the set-screws of both of its pivots, plac ing the thumb and a finger of one hand against the heels of the respective pivots, moving the pivots and pedal bodily sidewise to the de-v sired position, and retightening the screws. This facility of adjustment is not possible with pedal-bearings heretofore employed.

My improved pedal bearing and support as a whole is strong, light, compact, and durable.

I claim- 1. In combination, a base having integral standards, two or more pedals, pivots loosely fitted in sockets in said standards and adapted to slide longitudinally thereof, and set-screws screwing laterally through said standards and adapted to bind the pivots in the standards, substantially as and for the purpose set forth.

2. In con1bination,a base having four stand ards rising therefrom, each of the outer standards having a single pivot adj ustably mounted therein and each of the two intermediate standards having two pivots adjustably standards and the pivots carried by the outer mounted therein and extending in opposite standards.
