ABSTRACT:
A compound bow carries eccentrics, each of which has a non-circular string groove with a geometric center removed from the axis of the eccentric and a take-up groove which is out of registration with the string groove about substantially the entire peripheries of the grooves. The two grooves are carried by respective sheaves rotatably joined through a hub which is itself rotatably connected to one of the sheaves. Other aspects of the present invention relate to a unique idler used in combination with a single-cam embodiment of the present invention.
