The attachment comprises a plate attached to a midpoint on the bow and an elongated rod having one end adapted to engage the bow string and its outer end pivotally secured to the plate. The rod is pivotal between a first position in which the rod extends outwardly from the bow and engages the midpoint of the bow string to maintain the bow string in a partially drawn pre-cocked position. When the bow string is moved to its fully cocked position, the rod under the force of gravity pivots downwardly to its second position and out of the way of the bow string to permit the normal operation of the bow.

Abstract: A bow mounted quiver includes a storage apparatus for releasably housing a plurality of arrows on one side of the bow and a counterweight mounted on an opposite side of the bow to compensate for the twisting torque produced by the weight of the storage apparatus and the arrows contained therein. Both the counterweight and the storage apparatus are secured to the bow by means of externally threaded shaft members. In a preferred embodiment, one counterweight threadably engages the external threads on the shaft member and is rotatable thereon so as to vary the torque produced thereby. That is, as arrows are removed from the quiver, the counterweight may be rotated clockwise so as to cause its movement toward the bow. As arrows are added to the quiver, the counterweight is rotated counter-clockwise increasing its distance from the bow and thereby increasing the torque produced thereby.

A string engaging member is carried adjacent the outer ends of each of the arms. A pair of pulleys are carried adjacent each remote end of the limbs. A bow string has opposed ends thereof attached to a respective inner end of a respective arm. The string extends around the pulleys on the ends of the limbs and the string engaging members so that when a notching portion of the string is drawn for shooting an arrow, the pivotal arms are pivoted from an open extended position to a partially closed position providing a uniform draw of the string when drawing the string from a released position to a fully drawn position. A pair of eccentric cams are carried adjacent the arms over which respective opposed end portions of the string extends.

Abstract: An archery bow wherein the draw weight increases as a function of draw displacement to a point just short of maximum draw displacement, such that the draw weight is substantially reduced at maximum draw string displacement.First and second levers fixed together at approximately a 90 degree angle are rotatably coupled to a support arm fixed to the bow body. The bow string is anchored at each end to the first lever ends and disposed about pulleys connected at the bow limb ends. Separate limb tension cables are anchored between the limbs and pivotal rollers connected at the ends of the second lever. Rotation of the second lever (and pivotal rollers) approximately 90 degrees by displacing the bow string toward its maximum position causes each roller to move onto a fixed flat surface, substantially reducing the draw weight on the bow string just short of maximum draw displacement.

Abstract: A bow of the compound type for use in archery, having an upper and lower limb pivotally mounted at opposite ends of an elongated central frame member having a hand grasp portion formed thereon. First and second pivot members having continuously variable leverage characteristics are each connected to both the upper and lower limbs. When the drawstring is pulled back toward the cocked position, the limbs pivot and the variable leverage pivot members rotate from the position of least leverage to positions of progressively greater leverage. Thus, less force is required as the drawstring approaches the fully cocked position. When the drawstring is released, the variable leverage pivot members operate in reverse to progressively increase the velocity of the drawstring as it snaps from the cocked to the fully released position.

Abstract: Compound bow having two eccentric wheels or cams at each end. One of the wheels may be quickly manually adjusted with respect to the other without disassembling the strung bow to adjust the magnitude of drop off at full draw without significantly changing the draw length or peak weight.
