lower cymbal 100 supported on stand not shown and upper cymbal 101 coupled to the control rod 102 through the locking mechanism to be described in particular the domed portion 103 of the upper cymbal 101 is retained by block 104 that is slidable on the control rod 102 the block 104 is connected to a collar 105 providing mating surface 107 with recess 106 forming part of the clutch mechanism clutch housing 108 is coupled to the control rod 102 and moves up and down with it the housing 108 pivots on ball 109 affixed to the control rod when the strike ring 110 is struck the lower mating surface 111 of the housing 108 contains recess magnets which normally engage magnetically with the mating surface 107 to of the collar 105 to hold the two parts together and hold the upper cymbal in the locked position so that it moves with the control rod 102 in addition a resilient member which in this embodiment is a compression spring 112 is mounted between the mating surfaces 107 111 with its lower end fitted into recess 106 the spring 112 acts to tend to force the mating surfaces 107 111 apart extra magnets are provided so that in the engaged position the magnetic attraction overcomes the force of the springs the spring 112 may be a 15.
