Abstract: Eccentrics for a compound bow are provided with a string sheave and a cable sheave, at least one of which is provided in segments adjustable to alter the course of the cam ratio effected through the eccentric. Ideally, the portion of the cable sheave corresponding with post peak force-draw positions is adjustable to alter the separation of the cable from the pivot axis of the eccentric at the valley position of draw.

Abstract: A quiver mounting system for archery bows includes a rotational coupling-decoupling mechanism and a two-point attachment mechanism to provide for rapid attachment or detachment of a quiver in the field, as well as a stable mounting. The rotational coupling mechanism is located at a first point and includes a socket having an opening of irregular configuration and a connector resiliently extending through the opening and engaging the exterior wall of the socket. The socket is connected to the bow and the connector to the quiver. When the connector is rotated relative to the socket, it passes through the opening and the quiver is decoupled from the bow. The quiver is also detachably connected at a second point to the bow. The connection at this second point must be detached to permit the relative rotation between the socket and connector.
