Patent number: 5174702Abstract: A lug nut retainer that holds a lug nut in position proximate to a wheel lug hole to accept a stud extended through the wheel lug hole and for resiliently urges the lug nut onto the stud while allowing the lug nut to rotate to screw onto and off the stud. A resilient retaining clip is mounted onto the wheel to hold the lug nut in position near the wheel lug hole and to resiliently urge the lug nut towards the wheel lug hole. The retaining clip is fastened to the wheel lug hole by inserting an arm of the clip through two holes provided in the wheel. As an additional feature, a limit clip is provided that limits the motion of the retaining clip to decrease the likelihood that the retaining clip may be bent or damaged while allowing the retaining clip to be positioned on a nut. The lug nut is provided with a socket stop ring around which the retaining clip is positioned. The stop ring keeps the socket from rubbing against the retaining clip.Type: GrantFiled: February 4, 1991Date of Patent: December 29, 1992Inventor: Lee A. Dolin

Patent number: 4710080Abstract: The method of providing an improved soldered electrical connection includes the step of providing a ring over an electrical wire and a terminal which are to be soldered together, and then compressing the ring to form a mechanical connection between the wire and the terminal prior to soldering. The mechanical connection holds the wire for a substantial length against the terminal and prevents movement during the soldering thereby insuring against a cold solder joint. Preferably, the ring is divided with the free ends preferably being offset to provide ease in sliding past each other. Preferably, a specially designed tool is utilized to compress the ring, the tool being provided with specially designed grooves in its jaws for holding the ring on end.Type: GrantFiled: August 24, 1984Date of Patent: December 1, 1987Inventor: Howard H. Sheppard

Patent number: 4708558Abstract: A fastener having pointed ends for penetrating a belt. The preferred fastener is a wire hook fastener for joining the ends of belting and it is formed with pointed wedge-shaped ends defined by inclined top surfaces and flat bottom surfaces and inwardly inclined sidewalls extending between the top and bottom surfaces. The pointed wedge-shaped ends penetrate the belting and in a plane which coincides with the surface of the belting to limit deflection to form a uniform and strong joint between the wire hook fastener and the belting.Type: GrantFiled: February 21, 1986Date of Patent: November 24, 1987Assignee: Flexible Steel Lacing CompanyInventor: Edward C.

Patent number: 4699553Abstract: A releasable locking device for mounting in the bore of a shaft or the like for retaining an element thereon. The releasable locking device is in the form of a cotter ring comprising a one piece rod formed of flexible material and having a leading portion, a central portion and a trailing portion. The central portion is wound in the form of a helix so as to form more than one but less that two full helical turns with adjacent turns being separated by a distance insufficient for the rod to be freely trained through the bore of the shaft during mounting. The leading portion extends tangentially from the central portion so as to define a lead that is freely insertable into the bore, and the trailing portion is helically shaped in axially flared relation to the central portion in a manner that progressively increases the axial spacing between the trailing portion and the immediately adjacent turn of the central portion to facilitate removal of the device from a locked position.Type: GrantFiled: December 9, 1985Date of Patent: October 13, 1987Assignee: Roper CorporationInventor: Johnie N.

Patent number: 4638198Abstract: Electric submergible motor of the long, multi-rotor section type employed for driving submergible pumps has bearing assemblies between successive rotor sections that are isolated from axial loads. For this purpose, the upper rotor section of each pair of successive rotor sections may have its lower end supported on a rotor shaft protrusion, such as a ring mounted in an annular groove of the rotor shaft. A chamfer at the end of the rotor bore locks the ring in place.Type: GrantFiled: January 22, 1985Date of Patent: January 20, 1987Assignee: TRW Inc.Inventor: Susan Cochran

Patent number: 4627761Abstract: A flexible retainer for coupling an inner polygonal stud and an outer tubular member includes an elongated arm from which a pair of spaced fingers transversely extend. The outer tubular member includes a polygonal bore into which the inner stud is inserted in a telescoping manner. The inner stud includes a transverse hole which when aligned with diametrically positioned lateral apertures in the outer tubular member forms a generally transverse channel in the telescoping member combination. With the arm of the retainer positioned around a portion of the periphery of the outer tubular member, each of the fingers positioned thereon may be inserted within a respective lateral aperture of the outer tubular member so as to extend into the transverse hole of the stud in securely coupling the two telescoping members.Type: GrantFiled: September 28, 1984Date of Patent: December 9, 1986Assignee: Snap-on Tools CorporationInventors: Gene E. Olson, Norbert J. Kot
