Abstract: A cable exercise machine has the capability for allowing a user to perform various exercises by the lifting and lowering of weights by means of a cable. The cable is tethered at opposite ends on the frame of the machine and it passes through a sheave assembly and a sheave block assembly. The user pulls on the sheave block assembly to lift the weights. The sheave assembly is adjustably positionable on the frame of the machine to different positions and is operatively related with the cable and the sheave block assembly such that the sheave block assembly hangs free from the sheave assembly substantially the same amount for all adjustment positions of the sheave block assembly on the frame so that the user can remain in the same position relative to the machine for all adjustment positions of the sheave assembly. Additional exercise stations are provided, a seat and bench station, and a leg exercise station. These have adjustment capabilities and may be used in conjunction with the cable-operated weights.

The support member has a square head on one end which is vertically slidable in a larger vertically elongated rectangular recess in one side of the bow handle, a nut on the other end thereof when tightened clamps the support member in a vertically adjusted position, an arrow rest is attached to the outer surface of the square head, and a hollow cylindrical, externally screw threaded member carrying a spring pressed arrow spacing plunger slidable longitudinally therein is threadedly engaged in said support member for horizontal adjustment.

Abstract: A sportsman's or hunter's bow holder in which an elongated bow-supporting stanchion has an elongated slot for vertically adjusting the angle and elevation of the stanchion relative to a supporting bracket. The stanchion is provided with a bow-engaging fixed member in spaced relation to a resilient member for engaging and urging the bow frame against the fixed member for retaining the bow and having it readily accessible for use.

Abstract: A quiver is attachable to a conventional bow to position a series of arrows in rapidly following succession for discharge by the bowman. Disclosed is an attachment which can be bodily adjusted to operative and inoperative positions upon the bow, and when operatively positioned, will position an arrow directly upon the bowstring, as a response to discharge of another, preceding arrow. Discharge of an arrow causes the bowstring to shift an operating plunger in a direction to momentarily disengage a latch device from a spring loaded, rotatable magazine. The magazine, thus freed for rotation, turns through a predetermined angular distance to laterally displace the next arrow to be discharged. The nock of the laterally shifted arrow is caused to be positioned upon the bowstring. At the same time, the latching device returns to a position latching the magazine against further rotation, leaving it in proper position for displacement of yet another arrow to a ready-for-discharge position.

Abstract: An archer's compound shooting bow has rigging cables and pulleys arranged to eliminate torque on the limbs when the bow is fully drawn and to permit an arrow to fly true past the rigging when the bow approaches its rest condition. Each pulley has two grooves receiving an adjacent rigging cable. The grooves have variable separation at different locations along the pulley rim. Each pulley is mounted on a limb alongside the opposite rigging cable dead end. As to each limb, the connection of the opposite cable dead end and the location of the adjacent cable tensions are arranged, in respect to their magnitudes at full draw, to apply no net torsional moment to the limb about its torsional axis.The separation between the pulley grooves corresponding to the rest condition permits arrow feathers to pass the rigging cables without contact, which is not true at full draw. The groove for the shooting string is normal to the pulley rotational axis. The other groove is substantially helical to the first groove.

Abstract: An exercise device containing a frame having a front and rear section and an athlete's body receiving support elements, an operating element to rotatably receive the forces exerted by the members of the body of an athlete seated in the support elements, an eccentric rotatable element fitted to the operating section in order to direct the forces applied to the latter over to the eccentric element, a counter force element mounted on the eccentric element by a rope element in a manner that the counter-force element resists the force applied to the operating element with a counter-force by way of the rope element and the eccentric element. The operating element is connected to the eccentric element by two transmission gears flanking the support elements and by a substantially rope-shaped transmission element as well as by two rearward transmission gears, with the eccentric elements being mainly disposed behind the support elements, and that the transmission gears plus their transmission elements are encapsulated.

Abstract: There is disclosed an archery release mechanism for releasing the bowstring of a free-standing bow in which a latch mechanism for latching onto the bowstring has a wrist band for attaching it to the wrist of the archer. The latch mechanism has a trigger adapted to engage the latch mechanism and hold it in latching position when the trigger is fully retracted so that the bowstring is released when the trigger is released. The latch mechanism is constructed also so that the latching mechanism is held in latch position when the trigger is not retracted so that the bowstring can be released by a pull of the trigger.

Abstract: A portable elastic exercising device which may be worn by the user to tone or firm up the wrist, arm and shoulder muscles while exercising not only in the conventional positions of standing, sitting, or lying, but more specifically, since the device is completely independent of the need to be anchored to a fixed object, it thereby permits the user to exercise while walking, running, or jogging, and has a single length of elastic cord that is twice passed through a flexible sheath to encompass the user's waist and whose two ends are also enclosed inflexible sheaths to form handles. Handle loops are maintained by covered steel wire ties or other fasteners.
