Abstract
Abstract A means for maintaining cymbol pedal tightness includes a fixed fitting to which both a cymbol pedal is attached and to either end of which a spring fitting is attached. The other end of each spring fitting is attached to an adjusting fitting. The adjusting fitting is fixably disposed directly above the pedal. A depression of the cymbol pedal pulls downwardly on the fixed fitting causing the springs in the spring fitting to extend. A subsequent release of the pedal releases the tension on the springs allowing the pedal to return to its original position. The tension in the springs is adjustable by means of gears disposed within the adjusting fitting.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
231 words
A means for adjusting and maintaining cymbal pedal tightness, comprising: a base adapted to rest on a support surface; a first tube connected at one end to said base and supporting a lower cymbal, said first tube have a housing fixed thereto intermediate its ends; a draw rod connected at one end to an upper cymbal, said draw rod extending through said first tube and having its other end fixed to a plate; a pedal connected to said plate such that depression of said pedal causes said plate and draw rod to descend causing said upper cymbal to crash down on said lower cymbal creating an appropriate percussional effect, the improvement comprising: a pair of tubes connected at one end to said base and at the other end to said housing, each of said pair of tubes having a slot therein; an adjusting ring have gear teeth thereon; a pair of small, toothed gears engageable with said adjusting ring gear teeth; each of said small, toothed gears having a threaded rod fixedly connected thereto and extending into one of said pair of tubes; a coupling block rotatably threaded onto each of said threaded rods, said coupling block having a pin thereon extending into one of said slots; and a pair of springs, each having one end fixed to one of said coupling blocks and the other end fixed to said plate.
