Apparatus for enabling and disabling relative rotary movements between two members rotatable about a common axis comprises a plurality of circumferentially spaced locking pins carried by one of the members and a plurality of circumferentially spaced sockets in the other of the members, the pins and sockets being uniformly spaced from the axis of rotation and each of the sockets being of such size as to accommodate any one of the pins. The number of pins is different from the number of sockets. The angular spacing between adjacent pins is uniform, and the angular spacing between adjacent sockets is uniform, but different from the angular spacing between adjacent pins. The angular spacing between the pins and the sockets defines a ratio which is not a whole integer.

Adjustable rotary locking and unlocking apparatus for respectively disabling and enabling relative rotary movement, said apparatus comprising: a) a first member having a first hub; b) a second member having a second hub; c) means coupling said hubs for relative rotation of said hubs and said members about a common axis; d) a plurality of arcuately spaced locking pins carried by one of said hubs for movements relative thereto between retracted and projected positions; e) a plurality of arcuately spaced sockets in the other of said hubs, f) the spacing and number of said locking pins being different from the spacing and number of said sockets but said locking pins and said sockets being uniformly spaced radially from said axis, g) each of said sockets being of such size as to accommodate any one of said locking pins, h) relative rotation of said hubs about said axis enabling different ones but fewer than all of said locking pins to register with said sockets; i) means for moving any one of said locking pins that is in register with one of said sockets to its projected position in said one of said sockets thereby locking said hubs and said members against relative rotation; and j) means for moving any one of said locking pins from its projected position in said one of said sockets to its retracted position thereby unlocking said hubs and said members and enabling relative rotation therebetween.
