Abstract: A pool table having a playing surface with which ball accomodating pockets are associated. Pocketed balls are conveyed by a runway system via a trap toward a compartment at one end of the table that is accessible to a player. The trap has a gate operable to prevent passage of the object balls into the compartment. The operation of the gate is controlled by a latch which is movable between a first position in which it latches the gate in ball-blocking position and a second position in which it enables balls to pass the gate. The position of the latch is responsive to operation of a latch driving motor.

Abstract: A pool table having a playing surface with which ball accommodating pockets are associated. Pocketed balls are conveyed by a runway system via a trap toward a compartment at one end of the table that is accessible to a player. The trap has a gate magnetically latched in closed position so as to prevent passage of the object balls into the compartment until such time as a coin control mechanism is operated to effect unlatching and opening of the gate. The gate is maintained in its open position for a sufficient period of time to permit the passage of all the object balls from the trap to the compartment. Following movement of the last object ball past the gate the latter returns automatically to its closed, latched position.

Abstract: A compound bow includes a unitary cam assembly attached to a single handle-mounted pylon. The cam assembly is provided with a plurality of cam elements respectively engaged by two string cables and each of two power cables. All such cam elements are disposed in a plane 90.degree. to the plane passing from the bowstring and through the handle of the bow. A string cable controller, also carried by the pylon, reverses the direction of one string cable so both string cables become juxtaposed and simultaneously act upon the same portion of one of the cam elements.

Abstract: A crossbow includes a trigger mechanism providing positive setting or cocking and release of a drawn bowstring. As the bowstring is drawn, it is pulled rearwardly into a trigger assembly slot to momentarily rearwardly deflect and ride over a spring-urged string catch member. Deflection of the catch member in turn urges displacement of a safety element into locking engagement with a pivotal sear. A nose on the locked sear normally abuts the catch member to preclude its release of a bowstring cocked therebehind. Following manual displacement of the safety to an off position, squeezing of a trigger pivotally moves the sear nose clear of the catch member to permit the cocked bowstring to forwardly deflect and pass over the catch member as the bowstring leaves the trigger assembly and propels an arrow engaged thereby.

Abstract: A compound bow includes a single, integrated cam assembly supported by the bow handle and having separate, adjacent cam elements receiving string cable segments and power cable segments from the bow limb tips. All the cam elements are fixedly disposed relative one another and are mounted for arcuate displacement as a unit. The plurality of cam elements and attendant bow structure are disposed in a manner resulting in shortened limb tip travel for a given bowstring displacement. The draw length of the bow is readily altered without dismantling the bow cable components and without any tools by removing and relocating end portions of the power cables in selected ones of a plurality of retainer pockets in the cable assembly and further draw length modification is obtainable, without changing the bow peak draw weight, through interchangable power cable cams.

Abstract: A compound bow is provided with a hanger assembly for attaching wheels or cams and power cables to both bow limb tips and includes a pair of hanger members removably engageable with the distal portions of two split limb portions on each bow limb without the need for separate fastener members. A pair of side walls on each hanger member provide four laterally spaced apart points supporting a transverse axle adjacent each limb tip on the belly side of the limb. The axles in turn support the wheels or cams and respective ends of the power cables with the tension applied by the strung cables providing the sole force retaining each hanger assembly in place.

Abstract: A compression mold includes punch and cavity components fabricated from initially flat sheets of relatively thin metal. The sheets of each component are shaped, assembled and joined to provide box-like components defining mating mold surfaces yielding molded parts which may be straight or laterally and/or vertically curved. The hollow interior of the two components allows for the circulation therethrough of an appropriate heat transfer medium to permit molding of either thermosetting or thermoplastic compounds.

Abstract: A copound bow having low-rotation cams includes an improved anchor member adapted to releasably attach one end of both a bowstring and tension cable to each cam. The cams are formed with a main body or lobe joined to a secondary body or lobe and configured to provide an elongated throat therebetween with a planar cable/bowstring track or groove about the cam periphery. The opposed walls of the cam throat are configured to transversely or laterally receive the anchor member while precluding any longitudinal or radial displacement thereof as tension is applied to the cam member by the engaging ends of the bowstring and tension cable.

Abstract: An elongated spring member is formed of fiber reinforced plastics, particularly resin-impregnated glass fiber strands, and includes end provisions adjacent the two ends for the reception of attachment elements associated with the use of the spring. The spring includes parallel impregnated strands which have been wound about a rack provided with end supports following which the entire wound resinous product is placed within a mold cavity and cured to provide a spring member having integral, molded end provisions encircled by continuous, uncut reinforcing fibers with or without the inclusion of additional reinforcing material, and which is molded without the formation of any significant waste product. The improved spring member includes transversely disposed end provisions which may comprise a passageway or elongated end members encircled by the reinforced strands and the center axis thereof may be along the neutral axis of the spring body or alternatively, above or below the neutral axis.

Abstract: An adjustable arrangement for anchoring the ends of each tension cable in a compound bow includes a displaceable disc cradled in a bridle cable suspended from each bow limb tip. Each disc is provided with a plurality of holes, slots or notches variably spaced from the center of the disc such that the distal portion of a tension cable may be selectively anchored in any one hole, slot or notch thereby allowing tuning of each bow limb by the alternate positioning of the anchored portions of the two tension cables in the respective discs. The slidable, captive engagement between the disc periphery and bridle cable automatically insures maintenance of each tension cable end within a plane passing through the bow centerline.

Abstract: A compound bow includes improved low-rotation cam members eccentrically mounted upon the bow limp tips and each provided with an enlarged main body section, a reduced width intermediate section and an elongated terminal section generally defining an irregular kidney-shaped profile. A single cable groove or track extends continuously around the entire periphery of each cam and is disposed in a single vertical plane such that any stretch of cable extending between the tracks of the two cams will be substantially aligned with the bow center line. A single continuous cable stretch, having its opposite ends respectively joined to a bowstring and a tension cable, is sheaved about the track of each cam and is adjustably anchored thereto by means of a removable, lockable, rotating keeper whereby fine adjustment of the bow may be achieved without disassembly or removal of any cable lengths from the bow cams.
