Abstract
Abstract A drum head assembly for use in drums, tambourines, banjos, or the like. A polymeric film is stretched across an annular member having a U-shaped channel formed in cross-section along its edge. The film is stretched and forced into the channel by plug member and is adhesively bonded therein. The plug member extends above the channel and receives a second, similarly shaped annular member over its exposed edge to provide a finished surface as well as an easy means for attaching the assembly to a musical instrument shell.

Claims Analysis
Total Claims: 25
Claim 1
Independent Claim
149 words
An apparatus for mounting a head on musical instrument comprising: (a) a first annular hoop having a channel formed along the edge thereof; (b) a polymeric film which is stretched across the opening in the annular hoop; (c) an annular plug member which is inserted into the channel formed along the edge of the first annular hoop such that the polymeric film is shaped and stretched as it is forced into the channel by one rim of the plug member to contact an adhesive therein and such that the opposite rim of the plug member extends above the edges of the channel; (d) a second annular hoop having a channel formed along the edge thereof substantially identical to the first annular hoop, and disposed in complementary fashion to the first annular member so that the channel covers the opposite rim of the plug member to form a drumhead assembly.
Claim 2
Independent Claim
149 words
An apparatus for mounting a head on musical instrument comprising: (a) a first annular hoop having a channel formed along the edge thereof; (b) a polymeric film which is stretched across the opening in the annular hoop; (c) an annular plug member which is inserted into the channel formed along the edge of the first annular hoop such that the polymeric film is shaped and stretched as it is forced into the channel by one rim of the plug member to contact an adhesive therein and such that the opposite rim of the plug member extends above the edges of the channel; (d) a second annular hoop having a channel formed along the edge thereof substantially identical to the first annular hoop, and disposed in complementary fashion to the first annular member so that the channel covers the opposite rim of the plug member to form a drumhead assembly.
Claim 3
Dependent Claim
12 words
The apparatus of claim 1 wherein the polymeric film is a polyester.
Claim 4
Dependent Claim
24 words
The apparatus of claim 2 wherein the polymeric film is the biaxially oriented film of the condensation polymer of ethylene glycol and terephthalic acid.
Claim 5
Dependent Claim
15 words
The apparatus of claim 2 wherein the polyester film is laminated to a spunbonded olefin.
Claim 6
Dependent Claim
16 words
The apparatus of claim 1 wherein the channels have a generally U, V or J-shape configuration.
Claim 7
Dependent Claim
21 words
The apparatus of claim 1 wherein said apparatus is secured along the edges of the shell of a musical instrument cavity.
Claim 8
Independent Claim
145 words
The method for manufacturing a drum, which method comprises: (a) forming an annular member having a channel formed along the edge thereof; (b) stretching a polymeric film across the opening in the annular hoop; (c) inserting an annular plug member into the channel formed along the edge of the first annular hoop such that the polymeric film is shaped and stretched as it is forced into the channel by the rim of the plug member to contact an adhesive therein, and such that the opposite rim of the plug member extends above the edge of the channel; (d) placing a second annular hoop having a channel formed along the edge thereof substantially identical to the first annular hoop in such a position that the opposite rim of the plug member is covered by the channel of the second annular member to form a drumhead assembly.
Claim 9
Independent Claim
145 words
The method for manufacturing a drum, which method comprises: (a) forming an annular member having a channel formed along the edge thereof; (b) stretching a polymeric film across the opening in the annular hoop; (c) inserting an annular plug member into the channel formed along the edge of the first annular hoop such that the polymeric film is shaped and stretched as it is forced into the channel by the rim of the plug member to contact an adhesive therein, and such that the opposite rim of the plug member extends above the edge of the channel; (d) placing a second annular hoop having a channel formed along the edge thereof substantially identical to the first annular hoop in such a position that the opposite rim of the plug member is covered by the channel of the second annular member to form a drumhead assembly.
Claim 10
Dependent Claim
12 words
The method of claim 7 wherein the polymeric film is a polyester.
Claim 11
Dependent Claim
24 words
The method of claim 8 wherein the polyester film is the biaxially oriented film of the condensation polymer of ethylene glycol and terephthalic acid.
Claim 12
Dependent Claim
15 words
The method of claim 8 wherein the polyester film is laminated to a spunbonded olefin.
Claim 13
Dependent Claim
18 words
The method of claim 7 wherein each of the channels has a generally U, V or J-shape configuration.
Claim 14
Dependent Claim
28 words

Claim 16
Dependent Claim
114 words
A drum comprising: (a) a first annular member having a channel formed along the edge thereof; (b) a polymeric film which is stretched across the opening in said first member; (c) a plug member which is inserted into the channel formed along the edge of the first annular member such that the polymeric film is shaped and stretched as it is forced into the channel to contact an adhesive therein and said plug member extends above the channel of the first annular member; and (d) a second annular member having a channel formed along the edge thereof disposed in complementary fashion to the first annular member and covering the extension of the plug member.
Claim 17
Dependent Claim
114 words
A drum comprising: (a) a first annular member having a channel formed along the edge thereof; (b) a polymeric film which is stretched across the opening in said first member; (c) a plug member which is inserted into the channel formed along the edge of the first annular member such that the polymeric film is shaped and stretched as it is forced into the channel to contact an adhesive therein and said plug member extends above the channel of the first annular member; and (d) a second annular member having a channel formed along the edge thereof disposed in complementary fashion to the first annular member and covering the extension of the plug member.
