Patent number: 4014219Abstract: A steering shaft coupling for a motor vehicle steering column constructed to join a steering shaft with a steering gear. The coupling has a pair of coupling parts and interconnecting members assembled to transmit driving torque from the steering shaft to the steering gear during normal operating conditions. The interconnecting members disengage the coupling parts when the steering gear is displaced axial toward the steering shaft in response to an axial force whereby said axial force will not be transmitted to the steering shaft.Type: GrantFiled: November 10, 1975Date of Patent: March 29, 1977Assignee: Ford Motor CompanyInventors: James R. Feustel, Alex Rhodes

Patent number: 4014151Abstract: Coupling structure for artificial stone parts such as concrete plates etc., have an anchoring member partially embedded in the stone with a head projecting therefrom and releasably inserted in a coupling member of C-shaped cross-section e.g. for suspension but permitting limited turning on an axis longitudinal to the C-groove of the coupling member, so that lateral forces are reacted into the anchoring member. Additional features include support flanges on the anchoring member; bent off portions of the anchoring member with additional members; wire loops for improving anchoring; and special bayonet-like insertion and locking of the head in a particular type coupling member.Type: GrantFiled: June 1, 1976Date of Patent: March 29, 1977Assignee: Mannesmann Leichtbau, GmbHInventor: Dieter Erhart

Patent number: 4004425Abstract: In a tandem master cylinder main and secondary pistons are interconnected by a rigid sleeve. One end of the sleeve is secured to one of the pistons, and an inwardly projecting lip or flange on the other end of the sleeve provides an abutment for a head on an axial stem extending from the other piston towards the said one piston. The head is axially slidable in the sleeve and is introduced into it through an opening in the wall of the sleeve, which opening is connected by a longitudinal slot to the end of the sleeve which is provided with the lip or flange.Type: GrantFiled: April 7, 1975Date of Patent: January 25, 1977Assignee: Girling LimitedInventor: John Flory Pickering

Patent number: 3999876Abstract: A coupling device including a first member that is formed with a hooked-shaped element having a circular opening and an elongated slot that communicates with said opening, and a second member having a connecting portion that includes a circular bar and at least one leg interconnected thereto, said bar and leg being movable through said slot in oriented relation for location in said opening, wherein the bar is rotatably positioned in the opening in the hook-shaped member for coupling the members together for relative movement therebetween. A resilient friction element is mounted on the first member and partially extends into and obstructs the entrance portion of said slot as formed therein so as to prevent the members from being inadvertently disconnected.Type: GrantFiled: December 15, 1975Date of Patent: December 28, 1976Assignee: FAS/CON Systems, Inc.Inventor: Isaac F. Manchester, Jr.
