Abstract: An exercise machine primarily used in exercising and strengthening muscles and ligaments not normally affected by the standard dynamic and/or isometric approaches. The machine causes the user to work against a centrifugally operated brake which increases the resistance to movement as the rate of movement increases. A horizontally disposed lever including a stirrup is rotated about a vertical shaft by the foot and leg of a user, and the shaft is functionally connected to a speed increasing mechanism and its rate of rotation is regulated by a centrifugal brake. The amount of effort being expanded to overcome the brake resistance is displayed by a simple linkage from the brake mechanism to an easily visible indicator.
Abstract: A compound archery bow of simplified construction includes a bowstring secured intermediate its ends to eccentrically pivoted cams mounted at the outer ends of the limbs secured to the opposite ends of a handle member. A control cable connects each cam pivot shaft, and therefore each limb, to a laterally projecting post on a lever mounted pivotally on the end of the handle member that secures the opposite limb. The end segments of the bowstring are trained around the cams and through the diametric center of each cam wherein the segments are secured. Each terminal end portion of the bowstring end segments is secured either to a winch located on the lever mounting the associated cam, or directly to said lever. The connection of the limbs to each other through the control cables and the bowstring end segments secured to the levers balance the flexure of the limbs relative to each other as well as the rotation of each cam as the bowstring is drawn back.

Abstract: The archery bow has springs in the string system at each limb of the bow. Due to a high spring rate the springs do not deflect appreciably when the bow is drawn but do deflect substantially when the bow limbs pass the at-rest position after being shot. This allows the limbs to overtravel the at-rest position and be cushioned thereby reducing the shock to the bow and its components.
