Abstract: An asbestos-free clutch plate assembly has a reduced break-in phase and a facing which is substantially uniformly supported by the clutch plate. The assembly comprises a clutch plate defining a first surface and having a plurality of cambered portions. A substantially rigid, wear resistant, asbestos-free facing is attached to the first surface. The clutch facing has a plurality of grooves formed therein with each groove located substantially along the peak of one of the cambered portions thereby reducing the amount of material to be worn away during the break-in phase. The grooves further enable the clutch facing to conform to the contour of the surface so as to be substantially uniformly supported thereby.

Abstract: A tool for applying a fastener having rod engaging tongues to a rod comprising a support tube; a rod clamping assembly mounted in said, and movable longitudinally relative to said tube; a lever arrangement pivotally connected to said assembly for producing said relative movement; a release projection mounted in said tube and adapted to cooperate with said clamping assembly to release a said rod when gripped thereby; and a spring biasing said clamping assembly, in the direction opposite to said relative movement, into cooperation with said release projection; said tube being adapted to cooperate with a said fastener and, upon operation of said lever arrangement to produce said relative motion, to move said fastener along a said rod when engaged by said clamping assembly.
