Patent number: 4995755Abstract: 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.Type: GrantFiled: May 23, 1989Date of Patent: February 26, 1991Assignee: Toyota Jishoda Kabushiki KaishaInventors: Youichi Hyodo, Tadao Muramatsu, Takaji Hattori

Patent number: 4798569Abstract: An emergency belt assembly is provided for temporary replacement of broken fan belts and the like. The assembly comprises a tubular belt made of an elastomeric material, and a connector having a shank with a plurality of barbs on each end portion thereof. The maximum outer transverse dimensions of the barbs on each end portion of the connector decrease from the axially outermost barb to the axially innermost barb, thereby permitting the connector to be easily inserted manually into the tubular ends of the belt. In an alternate embodiment, the connector articulates at a point intermediate its end portions to permit the connector to easily accommodate small radii turns. In yet another embodiment of the present invention, the connector has a plurality of barbs on one end thereof for frictionally engaging the inner surface of a tubular end of a line or belt, and has on its opposite end portion an attachment member, such as an eye, for attaching to a support object, such as a pole, wall, or the like.Type: GrantFiled: April 28, 1988Date of Patent: January 17, 1989Inventor: Earl L.

Patent number: 4507008Abstract: A cable termination arrangement includes a tapered socket body and a mating plug covered with a sleeve of malleable material. Cable strands are inserted and spread out inside of the socket. The plug and sleeve are pushed into the socket for forcing the strands into the sleeve. When a tensile force is applied to the cable, slippage between the cable and the socket is zero.Type: GrantFiled: May 13, 1983Date of Patent: March 26, 1985Assignee: AT&T Bell LaboratoriesInventors: Ali Adl, William D. Backus

Patent number: 4461116Abstract: A connecting member comprising an elastically deformable, tubular plug (1) slitted at the ends for interconnecting pairs of building components (9a,9b), which have coupling holes (8a,8b) to receive the ends of the connecting member, has apertures (3) in the plug wall between the slits (2), and the plug wall is formed with lengthwise extending clamping wedges (4) between the apertures (3), said clamping wedges having inclined faces which slope towards the ends of the connecting member and causing the connecting member to be compressed at the center and be expanded at the ends when it is pressed into a pair of co-axial holes in adjacent building components. The connecting member may in particular be formed with an annular flange (5) and end beads (6a,6b) which fit in corresponding annular grooves (7) in a pair of adjacent components (9a,9b).Type: GrantFiled: September 8, 1982Date of Patent: July 24, 1984Assignee: Interlego A.G.Inventor: Erik Bach

Patent number: 4416562Abstract: A multi-partite assembly, for example an assembly including a housing and a cover, has a centering sleeve received in bores formed, respectively, in the housing and in the cover. The diameter of the bore made in the housing is relatively smaller than the diameter of the bore formed in the cover and the diameter of the centering sleeve. The sleeve is slidably received in the bore of the cover and press-fitted in the bore made in the housing, thereby the reliable alignment of the housing and the cover is obtained.Type: GrantFiled: December 3, 1980Date of Patent: November 22, 1983Assignee: Robert Bosch GmbHInventor: Claus Jons

Patent number: 4389829Abstract: A roof system of the type wherein a rafter and a purlin are connected by a sheet metal truss. The truss contains a pair of channel-shaped mounting flanges that are hinged to the member at each end thereof. One flange is adapted to pass over and be seated upon the rafter while the opposite flange is adapted to pass over the purlin. In assembly, the flanges are brought into alignment with holes formed in the rafter and the purlin and the truss is secured in place using a spring loaded truss pin that can be easily deformed in assembly to provide a rivet-like connection between the cojoined members.Type: GrantFiled: December 22, 1980Date of Patent: June 28, 1983Inventor: Wesley T.

Patent number: 4010533Abstract: The method for producing the transmission device including coupling means connected to a sleeve comprises forming a collar from an apertured blank of the coupling means and cold forming projecting portions on the outer surface of the collar for connecting the collar to rotate with the sleeve. The projecting portions may be formed by expanding the collar in a die from which die the collar is removed before connection to the sleeve. Alternatively, the projecting portions may be formed by radially expanding the collar in the sleeve whose inner surface has projecting portions which form the projecting portions of the collar upon contact with the collar during the expansion of the latter.Type: GrantFiled: December 4, 1975Date of Patent: March 8, 1977Assignee: NadellaInventor: Alfred Pitner
