  • Publication number: 20170191788
    Abstract: An arrow rest assembly includes a body, shaft, bidirectional bias mechanism, launcher, and rotation stop. The shaft rotates about a transverse axis and the launcher and rotation stop are secured to the shaft. The bidirectional bias mechanism provides a bias torque that opposes rotation of the shaft in both directions away from a single shaft reference orientation. The arrow rest assembly can be structurally arranged to be cable-driven or limb-driven. If the launcher can be removably secured in each of first and second launcher orientations, then the arrow rest assembly can be readily converted between the limb- and cable-driven arrangements.

  • Patent number: 9506714
    Abstract: A pulley assembly for a compound bow comprises a draw cable pulley and a dual-groove power module attached to the draw cable pulley and adjustable among one or more positions and two orientations. A power cable is taken up into one of the two grooves depending on the power module orientation. Changing the power module orientation the power module position alters one or more of the bow's draw force curve, stored energy, draw length, or draw weight.

  • Patent number: 9423202
    Abstract: As a compound archery bow (binary cam or hybrid cam; having first and second pulley members, a draw cable, and a single, continuous secondary cable) is drawn and its pulley members rotate: (i) both pulley members let out the draw cable; (ii) a take-up pulley of the first pulley member takes up a first end segment of the secondary cable; (iii) a let-out pulley of the second pulley member lets out a portion of an intermediate segment of the secondary cable; and (iv) a take-up pulley of the second pulley member takes up a portion of the intermediate segment of the secondary cable. Engagement of the intermediate segment with the second pulley member substantially prevents slippage of the secondary cable.
