  • Patent number: 5224789
    Abstract: The invention concerns a coupling for the detachable connection of two components, preferably a shaft with a hub, which for transmission of a torque are rotatably connected with each other by form-fit. When using such plug or form fit connections such as between a roll journal and a coupling box in a rolling mill, large tolerances must be expected that express themselves in peripheral directions and have adverse effects on the surface integrity of the rolled material. The invention provides for a clamping element which preferably can be inserted in the hub, acted upon by hydraulic fluid to keep the shaft in place relative to the hub. The clamping element is of a two-part design and can be filled with hydraulic fluid through appropriate devices, so that the hub is tightly fastened on the shaft upon assembly. For removal of the hub from the shaft, the pressure in the clamping element is simply relieved.

  • Patent number: 5220907
    Abstract: A archery bow sight for use with a bow having a body and bow string. The archery sight includes a mounting member for mounting the sight at an intermediate location on the bow, generally in the grip area. A sight frame defines an opening or aperture through which extends at least one fixed cross hair which is generally aligned with the bow string. One or more sub-frames are slidable relative to the fixed frame, each having a generally horizontally extending cross hair. The sub-frames are relatively adjustable so that the individual frames and associated cross hairs may be adjusted for various shooting distances. A level may be associated with the sight to reduce the possibility of cant or tipping.

  • Patent number: 5219449
    Abstract: A connector for connecting the open terminal ends of two pipes. The connector includes a first and a second generally half circular partial bush each having an end which extends into one of the pipe terminal ends. A bolt tightened through one partial bush presses against the facing abuttable surface of the other partial bush to press the other partial bush outwardly causing the partial bushes to frictionally engage in the pipe ends. The bolt preferably extends non-radially along a chord of the circle defined by the bushes. Protrusions axially spaced from the bolt at the facing surfaces of the partial bushes helps distribute the pressing force of the partial bushes to both pipe terminal ends.

  • Patent number: 5217316
    Abstract: A one piece shaft which supports two rotatable members is provided with shafts for energizing the rotation and for controlling an energized force of each member separately. The shaft includes a shaft body which connects two hollow shaft bodies attached to each rotatable member unrotatably on the same central shaft axis so as to rotate relatively, two members attached unrotatably to the fixed member attached rotatably to both sides of this shaft, and two torsion bars bridged between the separated hollow shaft bodies and the cap member respectively.

  • Patent number: 5216865
    Abstract: An end connector structure for suspension ceiling grid systems provides a connector to connector lock on each side of the web of a through runner. The lock includes a lateral tear drop shaped protrusion providing a rearwardly facing exposed edge in combination with a lateral strap on an associated identical connector which also provides a rearwardly facing exposed edge. When tensile stresses are applied between the two connectors, the connector to connector lock is subjected to forces causing the associated rearwardly facing edges to engage and resist connector separation. The protrusion joins the adjacent portion of the connector material with bends having relatively large radius of curvature to reduce the weakening of the structure of the protrusion resulting from notch sensitivity. These large radius of curvatures result in substantially improved ultimate strength in the connector to connector lock when compared with protrusions formed with relatively sharp bends.

  • Patent number: 5213437
    Abstract: A serrated-shaft connection between a shaft (1) and a hub (4) has a large number of teeth (2, 5) that are located on the outer circumferential surface of the shaft (1) and the inner circumferential surface of the hub (4), respectively. The profiles (6) of the teeth (5) of the hub (4) are bent convexly in cross section. In such a connection, it is essential that the profiles (3, 6) of the teeth (2, 5) of the shaft (1) and the hub (4) should be bent differently in such a way that the profiles (3) of the teeth (2) of the shaft (1) will have distances above the top of the teeth that are different from those above the top of the teeth (5) of the hub (4). As a result, the tooth profiles of the shaft and the hub can mesh with each other during assembly so that a compressive connection that fits with great precision is obtained.

  • Patent number: 5211155
    Abstract: An eccentric pulley mechanism for a compound archery bow includes an inner eccentric wheel pivotally mounted on the distal end of a resilient bow limb, and an outer pulley wheel which is rotatable relative to the inner eccentric wheel. The inner and outer wheels respectively include rotationally offset detents and notches which are operative for interengaging the inner and outer rotating wheels when the bowstring is pulled to a fully drawn position. As the bowstring is being drawn, the outer pulley wheel and its notch rotate about the inner wheel until reaching a maximum draw where the detent and notch engage and the inner and outer wheels become operable for rotating as an eccentric wheel. When the bowstring is released the engaged inner and outer wheels eccentrically rotate back and impart an increased velocity to the bowstring as it propels an arrow.
