Abstract
A percussion instrument arm adapter, comprising in combination, a support at one end of an arm, the support including rod clamping elements positioned for relative adjustment to clamp a rod, structure for effecting the relative adjustment, one of the elements swingable relatively away from the other element when at least part of the structure is moved out of element adjusting position, and against a shoulder or shoulders resisting such movement.
Claims12
A percussion instrument arm adapter, comprising in combination:
- a) a support at one end of an arm, the support including rod clamping elements positioned for relative adjustment to clamp a rod,
- b) structure for effecting said relative adjustment,
- c) one of the elements swingable relatively away from the other element when at least part of said structure is moved out of element adjusting position, and against a shoulder or shoulders resisting such movement,
- d) a first hinge operatively connected with the one element to allow swinging thereof toward and away from the other element,
- e) a second hinge operatively connected with said structure to allow movement of said part out of element adjusting position,
- f) and including a spring exerting force tending to swing said one element away from the other element.
