  • Patent number: 4487566
    Abstract: A punching tool for use in a tablet making machine includes a body portion having at least one bore extending from an end of the holder a preselected distance into the holder. The bore is internally threaded a preselected depth. An interchangeable punch is threaded into the punch holder bore and extends a selected length from the holder. The end of the punch has an externally threaded portion and a cylindrical portion. The cylindrical portion is positioned between the threaded portion and the portion of the punch that extends outwardly from the holder. The cylindrical portion has a diameter that permits it to move freely without interference into and out of the internally threaded bore. The bore has an enlarged thread configuration provided with cylindrical bearing surfaces between threads. The punch threaded portion has a thread configuration corresponding to the configuration of the threaded bore to permit rapid engagement and disengagement of the punch in the bore.

  • Patent number: 4455990
    Abstract: A pulley adapted to be mounted at each end of a bow and so constructed as to permit adjustments in the eccentric axis of rotation relative to a bow. Each pulley at the end of a bow includes a pair of annular grooves positioned in spaced relation around the periphery of the pulley. A first and second set of slots extend radially through the rim portion of each pulley and into the first and second annular grooves respectively. The sets of slots are diametrically opposed on the rim. The cable is reeved about each pulley and positioned in a selected pair of slots so that a preselected amount of cable is positioned on the pulleys corresponding to a preselected draw length and/or draw weight of the bow.

  • Patent number: 4364124
    Abstract: A trouser construction includes a conventional fly portion formed by a pair of overlapping flaps integral with the trouser waist and including a conventional zipper-type fly closure. In one embodiment, a second or imitation fly portion is removably attached to the waist portion in overlying relation with the conventional fly to simulate the appearance of the trousers being worn with the fly in an open position. In a second embodiment, an imitation fly portion is sewn onto the outer trouser flap that conceals the zipper of the operative fly of the trouser. The imitation fly portion includes a pair of strips of material each supporting a zipper-type track. The strips of material are sewn together and positioned in overlying relation with the trouser flap thereby concealing the trouser flap. The pair of zipper tracks extend from the upper end of the trouser flap to a lower end where the tracks converge toward one another and meet at a slide portion which engages the zipper tracks.

  • Patent number: 4353346
    Abstract: A compound bow includes a pair of limbs that extend from opposite end portions of a handle member. Each limb has a free end portion which is rotatably and eccentrically mounted on a pulley. A continuous cable is reeved about the pulleys and extends between the free end portions of the limbs. The portion of the cable reeved about the pulleys includes devices for engaging sprockets of the pulleys in a manner to permit adjustments in the draw length and draw weight of the cable. A flexible portion of the cable extends between the pulleys and is arranged to receive the arrow. A rigid portion of the cable includes a pair of overlying rigid sections each extending from a respective pulley to the free end portion of the opposite limb. The flexible and rigid cable portions are aligned with the longitudinal axis of the bow to eliminate torque to the limbs at all times.

  • Patent number: 4337749
    Abstract: A pair of limbs extending from opposite end portions of a handle member. Each limb has a free end portion upon which is rotatably and eccentrically mounted a pulley. A continuous cable is reeved about the pulleys and includes an arrow string portion extending between the limbs for receiving the arrow. The cable portions extend from the pulleys and through a cavity in the handle member where they are supported by idler pulleys. The pulleys are eccentrically mounted by devices that permit adjustments in the eccentric axis of rotation of each pulley relative to a limb to effect a change in the draw weight and draw length of the bow. Each pulley includes a pair of annular grooves positioned in spaced relation around the periphery of the pulley. A first and second set of slots extend radially through the rim portion of each pulley and into the first and second annular grooves respectively. The sets of slots are diametrically opposed on the rim.

  • Patent number: 4259750
    Abstract: A trouser construction includes a conventional fly portion formed by a pair of overlapping flaps integral with the waist portion of the trouser and including a conventional slide fastener. In one embodiment a second or imitation fly portion is removably attached to the waist portion in overlying relation with the first or conventional fly portion to simulate the appearance of the trousers being worn with the fly in an open position. The imitation fly portion includes a flexible backing having spaced apart strips that support in a converging arrangement a pair of track elements or rows of teeth. Associated with the track elements is a fly closure device that is maintained in a lowermost position to present the appearance of an open fly where the backing simulates an exposed portion of the garment worn under the trousers. In a second embodiment the imitation fly portion is formed integral with the overlapping flaps of the conventional fly portion.

  • Patent number: 4244346
    Abstract: A compound bow includes a pair of limbs each having a first end portion connected to a handle member and a second or free end portion. A bracket is connected to a free end portion of each limb of a compound bow. The bracket has a limb engaging portion positioned in abutting relation with the limb free end portion and a pair of plates extending outwardly therefrom. A pulley is positioned between the plates and is eccentrically and rotatably connected thereto. A continuous cable is reeved about the pulleys. Aligned bores extend through the bracket and limb free end portion. Fastening members extend through the aligned bores to secure the bracket to the limb. The bores through the limb have a diameter greater than the diameter of the fastening members. Thus the fastening members are secured to the bracket but are removed from contact with the limb.
