1. 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.

2. The combination of claim 1 wherein the one element and said structure have interengaged relation prior to movement of said part out of said element adjusting position.

3. The combination of claim 2 wherein said part includes a threaded adjuster shaft, and an adjusting nut engaging said shaft and projecting away from said one element in said adjusting position.

4. The combination of claim 1 wherein said part includes a threaded adjuster shaft, and an adjusting nut engaging said shaft and projecting away from said one element in said adjusting position, said nut being a wing nut.

5. The combination of claim 1 wherein said shoulder is on the one element and extends in the path of movement of said one part.

6. The combination of claim 1 including a second combination as defined in a), b) and c) of claim 1 , the second combination being at the opposite end of the arm.

7. 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) and including a second hinge operatively connected with said structure to allow movement of said part out of element adjusting position,

f) said one element and said structure having interengaged relation prior to movement of said part out of said element adjusting position,

g) and wherein said part and said one element have tongue and groove interengaged relation prior to movement of said part out of said element adjusting relation.

8. The combination of claim 7 including a spring exerting force tending to swing said one element away from the other element.

9. 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) and including a first hinge operatively connected with the one element to allow swinging thereof toward and away from the other element,

e) and including a spring associated with said first hinge and exerting force tending to swing said one element away from the other element.

10. The combination of claim 9 wherein said shoulder or shoulders is or are on the one element and extending in the path of movement of said one part, said shoulder or shoulders configured to urge said one-element temporarily toward the other element as said part overrides said shoulder or shoulders upon being initially moved in a direction to carry an adjusting nut out of said element adjusting position.

11. 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) said shoulder being on the one element and extends in the path of movement of said one part,

e) and wherein there are two of said shoulders spaced apart and tapering toward one another to guide said one part for smooth releasing and centered movement,

f) there being a first hinge operatively connected with the one element, and a second hinge operatively connected with said structure,

g) and including a spring exerting force tending to swing said one element away from the other element.

12. 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 spring associated with said first hinge and exerting force tending to swing said one element away from the other element,

f) said shoulder is on the one element and extends in the path of movement of said one part,

g) and wherein there are two of said shoulders spaced apart and tapering toward one another to guide said one part movement.
