  • Patent number: 4995755
    Abstract: A ball joint includes a pair of generally hemispheric head members including facing surfaces. A bearing member is disposed between the facing surfaces. One of the head members is connected to a ball stud, the other includes a shank hole through which the ball stud passes. Both head members are enclosed in a ball seat which is deformed into conformity with a generally spherical outer surface of the combined first and second head members by a socket that is formed about them. An elastic member between the socket and the ball seat applies an axial force to said first and second head members, whereby a substantial preload on the ball joint permits take-up of wear during use.

  • Patent number: 4991882
    Abstract: A connector including a male member and a female member adapted to mate therewith. The female member is hollow and has an annulus defining a plane substantially perpendicular to its axis. There is a substantially cylindrical hollow nozzle within the annulus and the nozzle has an outer diameter smaller than the inner diameter of the annulus, thus defining a space therebetween. A hollow portion extends away from the male member and is being substantially coaxial with the nozzle. The male member is generally cylindrical and hollow. It is provided with a collar having an outer diameter smaller than the inner diameter of the annulus and an inner diameter larger than the outer diameter of the nozzle, whereby the collar occupies the space. The male and female members, when connected, form a passage for flow of fluids therethrough.

  • Patent number: 4974576
    Abstract: A method and apparatus for precisely positioning various components of a compound bow is accomplished through the use of a device which adjustably, but securely, holds a compound bow in either a vertical orientation for the positioning of the nock or a horizontal orientation for the positioning of the arrow shelf, sights and pulleys. The method and apparatus of the present invention effectively alleviates the built-in inaccuracies in shooting an arrow. More specifically, the user can accurately position the nock on the main bow string, precisely align the arrow shelf with the main bow string, accurately align the sight bar on the bow with the peep sight on the main bow string, and check the accuracy of the alignment of the pulleys.

  • Patent number: 4962952
    Abstract: A tube has a deflection section to allow it to align between two bores which are substantially coaxial. The tube has an inner wall, an outer wall, a first end and second end. The first end of the tube rigidly connects to the first member. The second end of the tube slidingly extends into the bore of the second member. The deflecting section has circumferential inner and outer grooves. These grooves extend in from the inner and outer walls of the tube. Each of the grooves has an axial thickness that is much less than the distance between the grooves. The axial thickness is also less than the radial dimension between the base of each groove and the adjacent wall of the tube. This provides substantial rigidity to the deflecitng section, yet allows slight deflection.
