Abstract: An improved exercise apparatus is disclosed which features a bench mounted on a frame and having rigid rotatable arms mounted at opposing ends of the frame for exercise of groups of leg muscles and arm muscles respectively. Both rotatable members are connected to rotatable disks which have a plurality of attachment points disposed on opposite sides of their axes for connection of a weight bearing member so that the direction of rotation of the disk and of the point at which its rotation starts to do work can be varied whereby a large number of differing exercises can be performed with relatively simple apparatus.

Abstract: An improved arrow support device to be used on archery bows, including a pair of elongated, generally non-resilient arrow support members, rigidly attached to a pivotable yoke member. The arrow support members are bound by the yoke member and oriented in relation to one another so that the arrow shaft contacting outer tips of the arrow support members present no obstruction to the passage of an arrow with fletching, upon discharge of a shot. The yoke member pivots about an axis oriented so that the arrow contacting surfaces of the arrow support members can move downwardly at an angle inclined toward the surface of the bow sight window. The yoke member is held against a stop by spring tension. When the arrow bends due to the initial impact of release, the yoke assembly pivots against the spring tension which will return the yoke assembly to the stop when the initial bend of the arrow shaft passes through the zero point of the "S" curve.

Abstract: A draw stop mechanism for a compound archery bow. The draw stop mechanism includes first and second draw stop members with each stop member being fixedly secured to one pass of the bow string and slidingly receiving an adjacent pass. In operation, for example, with a compound bow having at least three passes of the bow string through its pulley system between the ends of the bow, the first and second draw stop members are respectively secured to two of the three passes. Then, as the third pass is drawn back causing the bow string to move through the pulley system, the first and second passes move by each other in opposite directions until the first and second stop members abut one another. When they abut, the bow string has been drawn to the desired length. If a longer or shorter draw length is desired, one or both of the stop members can be selectively moved to other secured positions along the respective passes.

Abstract: An exercise assembly for use in water. The assembly has an elongated shaft supporting a plurality of fins at one end. During an exercise the user grips the shaft and forces the fins through the water which offers a resistance to movement of the fins.

Abstract: A saddle for the bar of a bar-type weight has a bar-receiving portion, arms that incline upwardly and away from that portion, and a socket-forming portion which defines a socket that extends downwardly relative to those arms to telescope downwardly over the upper end of a rod-like support; and that saddle is unitary in nature and is wholly devoid of joints between any of the bar-receiving portion, the arms and the socket-forming portion. The bar-receiving portion has a part thereof which is located above the level of one edge thereof so a gap will always exist between that edge and the bar of the bar-type weight. The upper ends of the arms have horizontally-directed outwardly-extending lips that increase the effective area of the saddle which can be engaged by the bar of a bar-type weight without directing that bar away from that saddle.

Abstract: Therapeutic apparatus having a frame that includes a pair of laterally spaced A-frames in part defined by a user's seat extending therebetween and seat supports. A pair of independent tubular guides are connected to the apices of the A-frames for pivotal movement about aligned transverse axes, and each of the guides has an elongated and resiliently extensible operating element reciprocably extending therethrough that is provided at its forward end with a laterally extending handle and at its rear end with a laterally extending and spring-mounted roller that is engageable with the user's back upon the user urging the operating element forwardly in its guide. Rocking of a guide and its element in a vertical plane by the user manipulating the associated handle causes the associated roller to roll up and down against the user's back. A foot operable crank is mounted at a position below and forwardly of the seat to enable the user to exercise his legs while exercising his arms and shoulders to massage his back.

Abstract: The bench press safety rest is essentially two adjustable bar supporting members attached symmetrically on each longer side of a weight lifting bench seat section. The attached adjustable bar supporting members should extend upwards and in position for the purpose of supporting a resting barbell immediately above the lower chest of differently sized persons when individually occupying the weight lifting bench for reclined arm press.

Abstract: A construction for compact catapults is described. An elastic cord is mounted and placed in tension by threading it through a number of grooved reels. The reels are rotatably fastened to capstans and thereby to a handle-equipped base. When a U-shaped pellet is hooked over a portion of the elastic cord, drawn back and then released, high acceleration forces are transferred to the pellet which then issues from the catapult.

Abstract: In a weight raising exercise device a pair of upstanding lever assemblies, pivotally mounted on an open framework, are manually moved, alternately, toward one end of the frame in a push and pull action for raising and lowering framework guided weights selectively connected alternately with the respective lever assembly by chains entrained over sprockets and engaged with the weights by switch actuated solenoids. A fulcrum axle assembly, mounted on the framework between and pivotally connected with the lever assemblies, permits both lever assemblies to be used in raising and lowering the weights.

Abstract: A toy baseball pitching machine that is particularly adapted to be used by children. The machine has a ball pitching arm that oscillates rather than rotates and is capable of pitching a plastic ball to a batter using an "underhand" method of pitching. The ball pitching arm is fixed to an oscillatable eccentric arm. The eccentric arm is connected to one end of an extension spring, and the arm carries a pivoted pawl. The pawl is engaged by a toothed rotating drive wheel to rotate the pitching arm in one direction toward a cocked position with the spring extended. Further rotation of the drive wheel brings the pawl into contact with a stop to pivot the pawl out of engagement with the drive wheel. The extended spring then acts on the eccentric arm and pitching arm to rotate the pitching arm in the opposite direction to engage and pitch a ball. The drive wheel, pawl, eccentric arm, stop and extension spring are all mounted within a housing; and the pitching arm is outside the housing.

Abstract: In the preferred and illustrated embodiment of an exercise device, a free standing frame with adjustable resistance assemblies mounted to the frame is disclosed.
