Abstract
Abstract A generally rectangular clamp body is provided with a vertical bore sized to and receiving the upper end of a cymbal stand vertical tube which coaxially supports a lower cymbal for tilting on the upper end of the vertical tube. A radial slot is provided within the clamp body to one longitudinal side of the clamp body and socket head cap screws mounted to one section of the body at the slot, engage tapped bores within the other section to reduce the gap at the slot and frictionally clamp the clamp body to the tube. The clamp body includes a rectangular cavity to the longitudinal side of the body remote from the socket head cap screws which slidably mounts, by a dovetail slot within a back plate and a dovetail projection of said sliding block, the sliding block for vertical movement over the vertical height of the cavity. A lead screw mounted for rotation within the clamp body has a threaded peripheral portion threadably engaged with a tapped hole within the sliding block. A thumb knob projecting externally of the clamp body and fixed to the lead screw permits rotation of the lead screw about its axis. A probe fixed to the sliding block and projecting outwardly of the top of the clamp body contacts the lower cymbal to one side of its vertical axis to effect tilting of the lower cymbal upon rotation of the thumb knob.
