Abstract
Abstract A clamping device for releasably mounting an instrument accessory includes a clamp member having an elongated channel formed therein, a worm shaft rotatably retained in the channel, a control device for rotating the worm shaft, a movable clamping jaw received on the shaft for reciprocal movement along the channel upon rotation of the shaft, and a fixed clamping jaw disposed adjacent to one end of the channel for cooperation with the movable clamping jaw. A support arm for supporting an instrument accessory is also provided which is mounted on the clamp member in a substantially universally-adjustable manner. The clamping device is especially intended for releasably mounting microphones and percussion accessories on the rims of drums.

Claim 1
Independent Claim
223 words
A clamping device for releasably mounting an instrument accessory, comprising: a clamp member having an elongated channel formed therein, a worm shaft rotatably retained in said channel, means for rotating said worm shaft, a movable clamping jaw received on said shaft for reciprocal movement along said channel upon rotation of said shaft, a fixed clamping jaw disposed adjacent to one end of said channel for cooperation with said movable clamping jaw, and a receiving bore and a threaded bore intersecting said receiving bore; a support arm for supporting an instrument accessory including a vibration-damping collar secured to one end of said support arm and an accessory support member having a knurled sleeve portion mounted in a friction-fit manner on said vibration-damping collar so that said accessory support member together with said instrument accessory may be rotated on said support arm; and means for adjustably mounting said support arm on said clamp member, including an integral split collar rotatably mounted in said receiving bore of said clamp member and having a bore formed therethrough in which said arm is rotatingly received, and a rotatable control knob having a threaded stem received in said threaded bore for engaging said collar to thereby tighten and loosen said collar to fix or release the rotatable position thereof and to secure or release said support arm received therein.
Claim 2
Dependent Claim
223 words
A clamping device for releasably mounting an instrument accessory, comprising: a clamp member having an elongated channel formed therein, a worm shaft rotatably retained in said channel, means for rotating said worm shaft, a movable clamping jaw received on said shaft for reciprocal movement along said channel upon rotation of said shaft, a fixed clamping jaw disposed adjacent to one end of said channel for cooperation with said movable clamping jaw, and a receiving bore and a threaded bore intersecting said receiving bore; a support arm for supporting an instrument accessory including a vibration-damping collar secured to one end of said support arm and an accessory support member having a knurled sleeve portion mounted in a friction-fit manner on said vibration-damping collar so that said accessory support member together with said instrument accessory may be rotated on said support arm; and means for adjustably mounting said support arm on said clamp member, including an integral split collar rotatably mounted in said receiving bore of said clamp member and having a bore formed therethrough in which said arm is rotatingly received, and a rotatable control knob having a threaded stem received in said threaded bore for engaging said collar to thereby tighten and loosen said collar to fix or release the rotatable position thereof and to secure or release said support arm received therein.
Claim 3
