Abstract

Abstract A practice pad for a drum or similar percussion instrument of the type fabricated of a construction material having sound-muffling characteristics and used in a directly supported position on the playing head of the drum, in the use of which all auxiliary structure to hold the pad on the drum vibrating playing head, and thus keep it in place, is eliminated. This is done simply by the advantageous selection of an appropriate weight oil-tanned leather as the construction material for the pad. In use, this specifically selected material has the proper weight to dampen, and thus muffle the drum auditory output and, also, by its sheer weight maintains a flat, surface-to-surface contact with the vibrating drum playing head, thus obviating any need for appropriate clamps or other structural members which typically are attached to the drum and to the pad.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 88 words
In combination a drum and a drum practice pad of the type fabricated of a construction material having sound-muffling characteristics and used in a directly supported position on the playing head of said drum, said pad comprising a flexible, oil-tanned leather in a flat disc-like shape sized to cover said supporting drum playing head, to thereby contribute by its weight both to a reduction in the vibratory motion of the drum playing head and to minimize any shifting movements of said pad relative to said drum playing head.
Claim 2
Dependent Claim 88 words
In combination a drum and a drum practice pad of the type fabricated of a construction material having sound-muffling characteristics and used in a directly supported position on the playing head of said drum, said pad comprising a flexible, oil-tanned leather in a flat disc-like shape sized to cover said supporting drum playing head, to thereby contribute by its weight both to a reduction in the vibratory motion of the drum playing head and to minimize any shifting movements of said pad relative to said drum playing head.
Claim 3
Dependent Claim 28 words
The improved oil-tanned drum practice pad as claimed in claim 1 wherein the leather has a weight in the range of five to seven ounces per square foot.
