PEDAL ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 767,247, dated August 9, 1904. Application filed May 3, 1904. Serial No. 206,240. (No model.)

To aZZ whom it may concern.-

Be it known that I, HARRY 0. Ross, a citizen of the United States, residing at Piru, in the county of Ventura and State of California, have invented new and useful Improvements in Pedal Attachments, of which the following is a specification.

This invention relates to a pedal attachment for pianos, the object being to provide a simple and sure means for closing the slots in the front boards of upright pianos and similar musical instruments to prevent mice and other vermin from gaining access thereto.

To this end I suspend from each pedal a removable hinged plate which closes that part of the slot below the pedal and as the pedal is operated rises and falls with it, being guided in its movement by passing through a slot in an angular extension from the pedal-plate beneath the piano.

In the accompanying drawings, Figure 1 is a front elevation of the lower part of an upright piano with my invention applied to the pedals. Fig. 2 is an enlarged sectional view on the line 2 2. Fig. 3 is a perspective view of the closure-plate detached.

Similar letters refer to the same parts on the various figures.

A indicates the front under board of an upright-piano case, to which is fastened at the bottom the usual pedal-plate B, slotted, as is also the board A at b, for the play of the pedals G.

As upright pianos are ordinarily constructed the slots 6 are left open, and it is through these slots that mice and other vermin enter pianos and do great damage thereto. To correct this defect, I suspend from each pedal a plate D, which entirely closes the slot below the pedal and forms an effectual barrier against destructive animals and insects should they attempt to gain access to the interior of the instrument.

Referring to Figs. 2 and 3, it will there be seen that the closure-plate D is placed immediately behind the pedal-plate B, its lower end extending through a slot in a foot or angular extension piece E of the pedal-plate B. The -upper end of each closure-plate D carries a supporting spring-arm d at each side, which arms detachably fit into and have hearings in depressions C on opposite sides of the pedal. It is not necessary that the closure-plates be fitted to guides in the sides of the pedal-plate B or front board A, the extension of the said plates through the foot-piece E being sufiicient for the purpose.

When a pedal O is depressed, the attached plate D is carried down with it, passing through the slot in the angular extension-piece E below the bottom of the piano, which being raised on casters prevents the plate D from reaching the floor. hen pressure is removed from the pedal, it rises as usual, the plate D following. It will thus be seen that the openings below the pedals are at all times closed. There being no openings above the pedals except when they are temporarily depressed, guards or protecting means at these points are unnecessary.

Having thus described the invention, what is claimed is 1. An attachment for pianos comprising pedals extending through suitable slots in the front board, a closure-plate for each slot, arms on the plates for suspending them from the pedals, and a fixed plate having an extension beneath the piano with a guide-slot therein.

2. An attachment for pianos comprising pedals extending through suitable slots in the front board, a closureplate for each slot, spring-arms on the plates for detachably suspending them from depressions formed in the pedals, and a pedal-plate attached to said front board and having a perforated extension through which the closure-plates pass and by which they are guided.

In testimony whereof I afiix my signature in presence of two witnesses.

HARRY C. ROSS.
