Tone hole pad for a wind instrument

Abstract

A tone hole pad to close a tone hole of a musical wind instrument is mounted in a cup having a bottom portion and a wall portion. A circular metallic base has a diameter substantially the same as the inside diameter of the wall portion of the cup and is brazed to the bottom surface thereof. The metallic base has a plurality of holes formed at regular intervals between the stem portion and the periphery of the surface thereof. A peripheral portion of the rear surface is beveled to conform to a curved portion of the inside bottom portion of the metal cup. A metallic holder, having an outside diameter substantially the same as the inside diameter of the wall portion of the cup, is provided with a wall portion with a lip which curves inward to prevent the pad's surface from floating and a ring-shaped recess formed in the peripheral upper surface thereof having an inside diameter smaller than the tone hole. A pad assembly of a felt body and an elastic resin plate is inserted in the metallic holder, mounted on the metallic base together with a mount paper, and fixed by a pad washer and a bolt.
