Abstract: An exercise device has an outer tank containing a supply of liquid and an inner container with mechanism for receiving a portion of the liquid from the tank when the container is in a first position and mechanism for discharging the liquid from the container at a controlled rate when in a second position. The inner container is connected to an elongated member that extends out of the tank and may be pulled upon by the user. A conduit may supply liquid under pressure selectively to the liquid container, in response to user demand as indicated by activation of a switch, and the liquid may then drain from the container through the same or a different conduit, to the original reservoir or a drain; and in this embodiment the container need not enter the tank or reservoir.
Abstract: A rotary exercise bar presenting an elongated central shaft, a pair of elongated handgrip portions oriented parallel and co-planar with the longitudinal axis of the central shaft, but offset on opposite sides thereof, and a pair of elongated, weight-receiving members coaxial with the central shaft and secured, respectively, to the outboard ends of the handgrip portions. The handgrip portions each employ an elongated, tubular handle revolubly mounted thereon, and the handgrip portions are each secured between the central shaft and the respective weight-receiving member by a pair of obliquely-oriented connector elements. Each weight-receiving member is adapted to have conventional free weights secured thereto, if desired. In use, the bar handles are grasped in the respective hands and the handles revolved around the central shaft. Free weights are added to the weight-receiving members, as desired, to increase the exercise resistance.
Abstract: A ball expelling device has a pair of soft, counter-rotating, coacting wheels mounted in a housing container on a pair of parallel spaced axles. A ball feed tube terminates in an outlet opening defined by a pair of opposed fingers at a location between opposed peripheral surfaces of the wheels. The ball feed tube is selectably positionable so that the outlet opening is moveable both in a direction perpendicular to the plane of the wheels and in a direction perpendicular to the plane of the wheel axles. A drive assembly operates to counter-rotate the wheels and preferably includes a pair of step-cone drive pulleys mounted on a pair of parallel drive axles with the drive pulleys each connected by a v-belt to a respective multi-stage pulley mounted on a wheel axle. The drive axles are interconnected by a transmission so that rotation of one drive axle causes rotation of the other drive axle in an opposite angular direction with equal magnitude.
Abstract: An archery bow having a primary energy storage device with a propelling bowstring attached thereto and a secondary and weaker energy storage device including bow limbs having a draw bowstring attached at opposite ends. The draw bowstring and the propelling bowstring are in draw force communication between a predetermined position on the propelling bowstring and the draw bowstring whereby force is applied to the propelling bowstring only at that predetermined position. The tension in opposite ends of the propelling bowstring and the force in opposite ends of the primary energy storage means is equalized and when released propels the arrow in a reproducible fashion without wobble or porpoising.
Abstract: A tubular sight for an archery bow is pivotally mounted on a bracket for securing the sight to the handle of an archery bow. A spring loaded locking ball is provided for securing the tubular sight in various predetermined angular positions relative to a horizontal plane for shooting at differing distances. The bracket is also adjustable laterally to permit variations in the horizontal distance between the tubular sight and the bow handle, and the sight may also be adjusted for windage. The spring loaded locking ball engages notches formed in a removable insert to permit simple adjustment of the sight under field conditions.
Abstract: A system for weight lifting exercises provides the user with a guided leg press/multi-press that has a safety mechanism which is adjustably limitable to prevent a barbell, an assembly of weight plates on a weight lifting bar, from falling below a chosen height. A series of holes in uprights provide a range of adjustment for barbell support rods during guided bench-press and standing-press use on a slide assembly permit a plurality of barbells to be received at one time, thereby increasing the weight-load capacity of the slider system. A part of the system serves as a chin-up bar. Numerous exercises using the system may be performed. A supported barbell includes a pivotal foot-plate with angle limiting provision. A slider assembly may include a two-piece apertured flange for locking a barbell in place during an exercise.

A firing pin is movably attached to the handle and has a first position disengaged from the jaws and a second position engaging the jaws. A firing element is attached to the handle for moving the firing pin from its first to its second position so as to move the jaws from their closed to their open position.
Abstract: A compound archery bow with a bowstring and coincident cable return runs in connection with an overcenter pulley at opposite bow limbs. A cable positioner adjacent the extremity of each bow limb embraces the cable return runs and prevents bowstring and cable interference in the operation of the bow.
Abstract: An improved ball pitching machine is described which can be easily adjusted so as to vary the trajectory of pitched balls, while at the same time affording maximum protection to by-standers by virtue of a selectively openable housing having an adjustable ball-clearing outlet. In preferred forms, the machine includes an elongated, rotatable ball pitching arm having a concave ball-receiving hand adjacent the outer end thereof; the hand is adjustably secured to the arm in a manner permitting variance of the angle of inclination of the hand relative to the arm, thus allowing the machine to deliver lob-type or essentially straight pitches as desired. The housing has an adjustable cover for varying the effective dimensions of the ball-clearing outlet, so that the outlet size can be correlated to a desired adjustment of the pitching hand.
Abstract: The apparatus has a striking mass which strikes a ball and a support for the ball to be struck. The ball is held to the support by a frame or by a suction apparatus. The ball may be given a curved trajectory by either rotating the ball support and ball or by rotating the striking mass at the time of impact.

Abstract: A compound bow with primary and secondary pulleys at the distal ends of the flexible limbs designed to reduce the draw force at the end of the draw. Pulley shape is designed to alter the force-draw curve to provide a flat plateau at the maximum draw which drops off again to the holding draw force. Draw length is controlled by curvature contour at segments of the secondary cable pulleys to achieve short, medium or long draw lengths with selective pulley segments which can be attached to a base primary pulley. A draw string pulley has a first perimetric section which is circular and a second connecting curved perimetric section which has a progressively decreasing radii from each end to the center with radii less than that of the first section. In some embodiments, three or four zones are provided. These zones can be created with add-on plates secured to a basic pulley.
Abstract: A ball throwing machine for hitting out tennis balls or the like at predetermined time intervals, in which a lock cover is rotatable or slidable into engagement with a switch which is capable of making and breaking an electric current to a drive motor. Said lock cover is mounted in a position adjacent to a rotating trace of a hitting lever. In the event an object other than ball, for example, a hand, a finger or a rod, should be drawn into the interior of the machine together with the hitting lever while this lever is rotated by a motor to expand a biasing spring, the lock cover will rotate or slide to break the electric current to the motor and stop the motor immediately, thereby preventing the occurrence of injury.
Abstract: A compound bow includes a handle portion and appended limbs, eccentric wheel assemblies mounted to each bow limb, and a cable attached at its ends to the bow limbs and extending over the wheel assemblies. Each wheel assembly includes a bowstring wheel having a peripheral groove, a first take-up wheel having a peripheral groove, and a central passageway communicating between the grooves to permit attachment of the bow cable. A second take-up wheel is secured to the bowstring wheel and includes a peripheral groove which is aligned with the groove of the first take-up wheel. The take-up wheels are configured such that the cable is not received in the groove of the second take-up wheel when the bow is in the relaxed condition, but is so received when the bowstring is drawn. The draw characteristics of the bow are therefore changeable by substituting various shapes of the second take-up wheel, and such substitution may be readily accomplished without requiring that the bow be dismantled or unstrung.
Abstract: An exercising machine for especially training the muscles of the leg includes a base on which a pair of support tables is rotatably carried, one for each foot, a vertical standard on the base adapted to provide fixed hand grips for a standing user or a seat for a sitting user, and a pair of resistance devices preferably formed by a selectable number of weights. Each resistance device is respectively connected by a cable and pulley system to one of the support tables to provide a variable reactive force as the associated support table is moved out of a neutral position. The seat and hand grips can be set at a selected height, the hand grips can be set at three positions in one horizontal plane, and the foot-supporting portion of each support table can be placed in a selected angular position by which the neutral or starting position is picked. The machine can be used close to a wall.
