Abstract
A screw stabilizer for selectively adjusting a first element with respect to a second element. The screw stabilizer includes a screw having a first end adapted to be supported on the first element and a second threaded end to be adapted to be threaded to the second element. First and second opposing washers are supported on the first end of the screw. The first washer includes a plurality of radially extending detents on the inner surface thereof. A plurality of ball bearings are sandwiched intermediate the first and second washers. The first end of the screw presses the first and second washers towards one another. The ball bearings selectively ride in the detents to selectively, releasably lock the screw in a desired position.

A screw stabilizer for selectively adjusting a first element with respect to a second element comprising a screw having a first end adapted to be supported by at least a portion of said first element and a second end having threads adapted to be selectively threaded to said second element, first and second opposing washers supported intermediate said first end of said screw and said at least a portion of said first element, said first washer having an inner surface facing said second washer, said inner surface having a plurality of radially extending detents thereon, and a plurality of ball bearings sandwiched intermediate said first and second washers to be selectively received in said detents to releaseably lock said screw in a desired position to prevent loosening of said screw.
The screw stabilizer as claimed in claim wherein said second washer includes an inner surface facing the inner surface of said first washer, said inner surface of said second washer including a plurality of radially extending detents thereon.
A screw stabilizer for selectively adjusting a first element with respect to a second element using a screw having a first end with an enlarged head for coupling to said first element and a second end with threads for screwing into said second element, comprising first and second opposing washers having openings therethrough to receive said screw, said first washer having an inner surface facing said second washer, said inner surface having a plurality of inclined surfaces thereon, and a plurality of ball bearings sandwiched intermediate said first and second washers to ride against said plurality of inclined surfaces.
A stabilizer for preventing undesired loosening of the lug screws coupling the rim of a drum to the shell of the drum, each said lug screw including a first end having an enlarged head and a second threaded end screwed to said shell, comprising a first washer fixed on the first end of said lug screw for rotation therewith, said first washer having an inner surface having a plurality of detents thereon, a second opposing washer on the first end of said lug screw and rotatable with respect thereto, a plurality of ball bearings intermediate said first and second washers, said first and second washers being captured intermediate said head of said lug screw and said rim of said drum to force said ball bearings to ride against said detents to releasably lock said lug screw in position.
