Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
58 words
A head for a musical instrument comprising a vibratile diaphragm section and a circumferential ring section of greater thickness than said diaphragm section, said sections being molded in a single operation from the same synthetic resinous molding composition as a unitary element whereby the head is stable against separation of said sections with changes in temperature and humidity.
Claim 2
Dependent Claim
58 words
A head for a musical instrument comprising a vibratile diaphragm section and a circumferential ring section of greater thickness than said diaphragm section, said sections being molded in a single operation from the same synthetic resinous molding composition as a unitary element whereby the head is stable against separation of said sections with changes in temperature and humidity.
Claim 3
Dependent Claim
19 words
A head according to claim 1 in which said ring section is contained within a circumferential channeled metallic ring.
Claim 4
Dependent Claim
18 words
A head according to claim 1 in which a metallic ring is contained within said circumferential ring section.
Claim 5
Dependent Claim
29 words
A head according to claim 1 in which said synthetic resinous molding composition comprises a resin selected from the group consisting of nylon, polyvinyl chloride, polycarbonate, polyoxymethylene and polyurethane.
Claim 6
Dependent Claim
15 words
A head according to claim 1 in which the molding composition comprises a polyurethane resin.
Claim 7
Dependent Claim
95 words
A head for a musical instrument comprising a vibratile diaphragm section and a circumferential ring section of greater thickness than said diaphragm section, said sections being molded in association with a continuous thin woven fabric in a single operation from the same synthetic resinous molding composition as a unitary element whereby the head is stable against separation of said sections with changes in temperature and humidity, said fabric being penetrated by said molding composition and being embedded therein in both said diaphragm and ring sections to render said head exceptionally strong and resistant to stretch.
Claim 8
Dependent Claim
