Abstract
Abstract An adjustable support for cymbals and other small percussion devices (traps), wherein a lug has provided therein means to define elongated parallel rails having relatively sharp edges. Mounted in the lug, and adjacent such rails, is a generally cylindrical shaft in which is formed a large number of longitudinal grooves adapted to receive the rail edges. A setscrew is provided to force the shaft against the rails, so that the rail edges seat in the grooves and lock the shaft against rotation whereby to prevent undesired movement of the cymbal (or other percussion device) which is connected to the shaft.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
212 words
A device for use in supporting percussion musical instruments, which comprises: a hollow lug having an open bottom; an elongated rail-defining member having a longitudinal groove in one side thereof; said rail-defining member being seated in said lug with said one side remote from said open bottom; the other side of said rail-defining member being adjacent said open bottom; fastener means to mount said lug on the shell of a drum with said open bottom adjacent such shell whereby said shell maintains said rail-defining member in said lug; a generally cylindrical arm seated on said one side of said rail-defining member; said arm having formed therein a large number of exterior grooves parallel to the axis of said arm and each adapted to receive an edge portion of said rail-defining memBer; said edge portions of said rail-defining member being on the opposite sides of said longitudinal groove therein; said edge portions being sharp and being spaced apart sufficiently far that circumferentially spaced grooves in said arm will simultaneously receive said edge portions; and a setscrew threaded through said lug on the side thereof remote from said open bottom to force said arm against said edge portions to thus maintain said edge portions in said grooves whereby to lock said arm against rotation.
Claim 2
Independent Claim
212 words
A device for use in supporting percussion musical instruments, which comprises: a hollow lug having an open bottom; an elongated rail-defining member having a longitudinal groove in one side thereof; said rail-defining member being seated in said lug with said one side remote from said open bottom; the other side of said rail-defining member being adjacent said open bottom; fastener means to mount said lug on the shell of a drum with said open bottom adjacent such shell whereby said shell maintains said rail-defining member in said lug; a generally cylindrical arm seated on said one side of said rail-defining member; said arm having formed therein a large number of exterior grooves parallel to the axis of said arm and each adapted to receive an edge portion of said rail-defining memBer; said edge portions of said rail-defining member being on the opposite sides of said longitudinal groove therein; said edge portions being sharp and being spaced apart sufficiently far that circumferentially spaced grooves in said arm will simultaneously receive said edge portions; and a setscrew threaded through said lug on the side thereof remote from said open bottom to force said arm against said edge portions to thus maintain said edge portions in said grooves whereby to lock said arm against rotation.
Claim 3
Dependent Claim
38 words
The invention as claimed in claim 1, in which said arm is employed in the support of a percussion musical instrument, and is longitudinally shiftable in said lug during periods when said setscrew is in a release position.
Claim 4
Dependent Claim
53 words
The invention as claimed in claim 1, in which said arm extends through openings in the ends of said lug, said openings being substantially larger than the diameter of said arm whereby to permit lateral movement of said arm relative to said lug to effect locking of said arm on said edge portions.
Claim 5
Dependent Claim
16 words
The invention as claimed in claim 1, in which said grooves on said arm are knurled.
Claim 6
Dependent Claim
37 words
The invention as claimed in claim 1, in which said longitudinal groove in said rail-defining member has a depth sufficiently great that the bottom wall of said longitudinal groove is always out of engagement with said arm.
Claim 7
Dependent Claim
36 words
The invention as claimed in claim 1, in which the spacing between the sides of said groove in said rail-defining member is such that the penetrated grooves in said arm are spaced circumferentially apart about 100*.
