  • Patent number: 9702656
    Abstract: The present invention is a self-aligning archery bow that has upper and lower risers and a grip intermediate the risers. A U-shaped handle overlying the grip is pivotally attached to the grip whereby the handle pivots about vertical axes in response to torque on the bow produced by force on the draw string, thus compensating for the tendency of the bow and the grip to twist in the hand of the archer. The pivotal movement of the handle is accommodated through a plurality of ball bearings that operatively engage the grip and the handle, and a pivotal bolt that connects the handle to the grip.

  • Patent number: 5992402
    Abstract: An arrow rest for an archery bow having a central bow riser, comprising a bracket adapted for attachment to one lateral side of the bow riser and where the bracket supports a pair of adjustably spaced apart disks that are disposed in a single plane that is perpendicular to the plane of the riser. An arrow shaft is supported by the thin circumferential edges of the disks. The bracket includes a guard shield that is elevated above the level of the disks and is spaced outwardly from the disks and the riser to protect the hand of the archer from the sharp edges of an arrow head that may be dislodged from the arrow rest and to limit the fall of the arrow.

  • Patent number: 5853001
    Abstract: An archery bow comprises a riser with upper and lower flexible limbs and a bow string defining a bow plane. A hand grip is provided, which may project laterally from the bow plane. A beam member interconnects the riser and hand grip. The beam member is adjustable fore and aft with respect to the riser and may be fixed in position with fasteners. The hand grip may be hingedly connected to the beam member. This arrangement allows the archer to adjust the position of the nocking point on the bow string when the bow is fully drawn.

  • Patent number: 5113604
    Abstract: A magazine having a casing with two compartments, one for cartridges to be fired and one for spare rounds. The compartment for receiving cartridges to be fired includes an opening for receiving the cartridges, a follower, a bias spring for urging said follower in a first direction towards said opening, and a manually actuated slide for overriding the bias spring and allowing the follower to move in a second direction away from said opening for loading and unloading of the cartridges in the compartment.

  • Patent number: 4879828
    Abstract: Our invention relates to an improved anti-curl feature for constant-force springs to be used in lifting a stack of shells by means of a follower in a multiple cartridge magazine for firearms thereby lessening the transverse curl in at least the uncoiled portion thereof that is responsible for causing its side margins to dig into the wall of the shell casing or bullet or both and cause jamming, such improvement comprising the localized weakening of spring along a longitudinally-extending line spaced between its side margins such that it lies flatter, preferably by providing same with a single column of longitudinally-spaced apertures or two or more such columns thereof in which adjacent pairs thereof are transversely misaligned. Our invention also encompasses the method of eliminating the aforementioned jamming problem by locally weakening the spring longitudinally such that at least its uncoiled portion lies flatter.

  • Patent number: 4787361
    Abstract: This invention relates to an archery bow characterized by a combination handgrip and forearm protector hingedly attached in closely-spaced parallel relation to the longitudinal axis of the bow defined by the limbs of the latter and the bowstring, the handgrip-forming portion of the combination unit extending laterally out to the side and rearwardly relative to the forearm-protecting portion so as to define an acute angular relationship therebetween. The handgrip and protector cooperate with one another to prevent rotation of the forearm holding the bow while at the same time concentrating the force exerted on the handgrip at the apex of the included angle therebetween which lies closely adjacent the hinge axis thereby causing the force applied by the protector against the forearm to be minimized.

  • Patent number: 4776122
    Abstract: This invention relates to a curved or angled multiple-round rifle cartridge magazine of the type designed for use with ammunition having tapered shell casings necked-down at their small end to accommodate a relatively smaller bullet characterized by a pair of negator springs attached for pivotal movement in spaced substantially parallel relation one behind the other to a sidewall of the shell chamber and a follower having front and rear side-opening spring-coil-receiving pockets for the coiled portions of the springs that permit the coils seated therein to tilt as the follower moves up through the chamber and the uncoiled portions of the springs change their angular relation to the latter and to the shell stack, both of the springs having medial portions lying between their coiled ends and the points of attachment to the magazine sidewall that curl inwardly toward the shell stack with the front spring of the pair being so located relative to the stack that its leading edge lies forwardly of the annular should

  • Patent number: 4580364
    Abstract: This invention relates to a rifle cartridge magazine for carrying and automatically feeding a plurality of rifle cartridges one at a time sequentially into the breech of a rifle characterized by a housing open at the top containing an arcuately-curved cartridge compartment therein sized and shaped to define a track effective to engage the front and rear ends of each cartridge and guide same into the breech, a pair of ribs depending from one face of the housing and extending into the cartridge compartment in spaced parallel relation to one another defining rails paralleling the front and rear ends of the track located in between the latter, a follower provided with spaced parallel slots extending transversely thereof on one side for riding the rails, the aforementioned slots and rails cooperating with one another to maintain the follower in substantially perpendicular relation to the track ends, and at least one constant force coiled clock spring having one end pivotally secured adjacent the open upper end of

  • Patent number: 3987899
    Abstract: This invention relates to a disposable molded plastic cap for covering as well as transferring heat to the heat-responsive probe of an electronic thermometer that is characterized by a small highly localized area in the tip that is extremely thin and is placed in heat exchange relation to the heat sensor of the probe so as to constantly transfer the heat from the patient thereto, such area being on the order of 0.001 inch thick. The invention also encompasses bordering said thin area with three or more integrally-formed ribs that radiate therefrom on the inside of the tip in angularly-spaced relation to one another where they cooperate to engage and keep the probe centered therebetween while, at the same time, maintaining minimal heat transfer contact therewith. In the preferred form of the invention these ribs have an essentially triangular cross section with the apex of said rib making line contact with the probe.

  • Patent number: 3952992
    Abstract: This invention relates to a novel inlay mold for use with a candle mold as a means for inlaying decorative molded wax inserts into one or more exposed faces of the latter while at the same time fusing them together to produce a unitary structure, such accessory including an open-topped shallow marginally-rimmed reservoir shaped to define a decorative insert into which molten wax is poured and allowed to set; and, hook-forming means for suspending said reservoir thus filled with wax in upright position from the rim of a candle mold flush against the wall thereof facing inwardly.
