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.

Abstract: An arrow rest for an archery bow which is readily laterally adjustable and has an arrow support which pivots upon movement of the arrow shaft and fletching across it and automatically returns to an initial predetermined position after discharge. The arrow rest mounts in a hole through the handle portion of the bow, provides easy lateral adjustment or complete replacement of the rest in the field.
Abstract: A yoke anchor for a compound bow is described which includes a semi-circular yoke portion having a perimetric groove for reception of the yoke cable affixed to the end of the bow limb and a central groove for reception of a terminal loop on the inside cable to be attached. A hook portion extends from one surface of the generally planar yoke portion and receives the other inside cable therein to cause the anchor and first inside cable to be pulled away from the bow string, thereby minimizing the chance of the bow string slapping against the yoke anchor or the inside cables during use.
Abstract: A resistance exercising machine having a similarly configured triangularly shaped main frame adapted to carry at least one stack of weights and a pivoted engagement mechanism which is operably coupled with the weights and is adapted to be engaged by the trainee to cause a controlled movement of the mechanism relative to the main frame against the urging of the weights.
Abstract: An extendable bench having a long front seat portion hinged to a short rear seat portion. Extendable support supports the bench at the hinge connection and at the front seat portion. Front and rear seat portions are independently tiltable. An arm with rollers engages arms and legs of a user and can be connected to the bench at various locations. The bench is extremely versatile and compact, and can be adjusted to any of its various exercise stations quickly, easily and without the use of tools.
Abstract: A hollow cylindrical, internally and externally screw threaded support member extends through a vertically elongated aperture from side to side through the bow handle and is vertically adjustable therein. 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: The assembly includes a compound bow having a cable guard in the form of a plate secured to the bow handle and an arm extending rearwardly thereof to deflect laterally the pulley cables out of alignment with the arrow rest for improved arrow vane clearance. A cable slide guide bearing smooth, spaced cable-receiving side grooves is integrally or separately connected to the cable guard. A novel drawcheck is utilized wherein an indicator component thereof is a flexible clicker blade or a light assembly with switch, the switch arm of which is connected to and extends from the slide guide in the path of travel of an activator component thereof. The latter is a protuberance, such as a head, block, cylinder or the like secured to one of the cables.
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: 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: 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 apparatus for muscular exercise where the user conducts a repetitive motion under load. The apparatus is coupled to the user to exercise the desired muscle group. When muscle is undergoing a shortening motion it is subjected to a load. At the completion of the shortening motion the load is automatically increased for the muscle-lengthening step. At the completion of the muscle-lengthening portion of the exercise the added load is automatically removed for the next muscle contraction step.
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.
Abstract: An exercising machine includes a pair of inclined guide tracks on each of which a foot-supporting member is arranged to slide frictionally, and the foot-supporting members are interconnected by an elongate flexible tension-bearing element, specifically a flat strap, which slides frictionally over stationary guides.
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 bowstring-held archery device which serves as an anchor point for an archer's pulling hand, the device having a body and a tail projecting from the body, the body having an arrangement for holding the device on a bowstring in fixed relationship thereto, the tail having sufficient length to project into the corner of the archer's mouth, whereby the bowstring-held archery device enables the archer to consistently duplicate the anchor point, and the device allowing the archer to see the bowstring during aiming without interfering with sighting of a target.
Abstract: The archery bowsight includes a base plate arranged for removable attachment to the handle portion of a bow and supporting a longitudinally extendable mounting arm which mounts at its forward end a horizontally adjustable bowsight windage carriage which, in turn, mounts an elevation carriage provided for micrometrically graduated vertical movement perpendicular to the plane of movement of the aforesaid windage carriage. An elongated sight pin mounting block mounts a plurality of sighting pins for individual adjustment parallel and perpendicular to the longitudinal dimension of the block in order to provide yardage and elevation adjustment of each pin for sighting on targets of various distances while also providing for horizontal adjustment of each pin for various windage conditions.
Abstract: An adjustable leg exercise device is provided which is easily configured for either a power hip, power leg, or hack squat exercise and is adaptable for safe use by athletes of different size and strength. The exercise device preferably includes a pair of parallel, spaced-apart, upwardly inclined rails each having a lowermost end secured to a floor-engaging base frame. Slidably mounted between the rails is a weight-receiving unit. Advantageously, the uppermost ends of the rails are interconnected by a yieldable structure permitting slight outward diverging movement of the rail upper ends during exercise thereby properly distributing the weight resistance to the athlete. An exercise unit positioning mechanism is included on at least one of the rails to permit adjustment of the starting position of the weight-receiving unit for accommodating various sized athletes. An adjustable bench is provided which is selectively positionable along the base frame from a use position to a stowed position.
