Abstract: An improved rivet is provided for joining a friction lining to a brake shoe. The rivet has a cylindrical body with first and second ends. A head is located on the first end of the body, and a hole is formed in the second end of the body. The hole terminates at a base within the body, the hole having a cylindrical surface that is concentric with the body, the base and the cylindrical surface being connected by a circumferential transition region. The hole depth, as measured from the second end of the body, is greater than the outer diameter of the body. In one embodiment, the transition region is a curved surface having a radius greater than one third of the radius of the hole. In another embodiment, the transition region has a conical surface that lies at an angle relative to the cylindrical surface and the base.

Abstract: A chuck includes a support and a plurality of pairs of oppositely disposed jaws with the jaws being movable to a position with each pair of jaws disposed on diametrically opposite sides of one element of an assembly. A motor moves selected pairs of the jaws into contact with the element and an additional motor moves the selected pairs of jaws and element away from the support to extract the element while at least one of the pairs of oppositely disposed jaws are maintained in position on the support to secure a second element of the assembly against movement while the selected pairs of jaws extract the one element.

Abstract: Apparatus useful in the manufacture and repair of automotive drive shafts which includes a frame and an elongate support bed rotatably mounting a multiple jaw chuck for rotary movement, a generally cylindrical workpiece passage extending through the chuck and its bearings and a pedestal remote from the frame and mounting an additional workpiece support axially aligned with the chuck. Stringers rigidly connect the remote workpiece support to the frame and a plurality of devices are mounted and movable relative to the support bed for selectively effecting operations on one end of a tubular workpiece supported by the multiple jaw chuck with the other end of said tubular workpiece supported by the remote workpiece support mounted to the pedestal.

Abstract: Machine for rapidly rotating and sensing imbalance of automotive drive shafts. Spindles including independent vibration sensors are rigidly secured to mounting blocks seated on a pair of rails integrally cast in a horizontal surface of a concrete base. A gear engaging a rack seated in a recess cast in the same horizontal surface senses to move one of the mounting blocks and its spindle and a plug also operable in the recess selectively locks the mounting block in position. Visual indicators are provided for simultaneously displaying vibrations sensed at each end of the driveshaft.
