Claim 1
Independent Claim
147 words
A drum body comprising: a hollow shell member defining a chamber therein and having at least one first opening therein adapted to be covered by a drumhead; and a plurality of hollow protuberant lugs extending outwardly from said member forming mounting lugs for apparatus to tension said drumhead over said first opening, each of said lugs having at least one peripheral edge contiguous with said member, all of said peripheral lug edges contiguous with said member being integrally joined to the member so that the member and lugs form an integral unit, and said member having a plurality of second openings therein corresponding in number to the number of said lugs, each of said second openings having substantially the same size and shape as the outline defined by said peripheral edge so that the volume of the chamber is enlarged by the internal volume of the lugs.
Claim 2
