Abstract: A method and apparatus for repeatedly testing wire rope and sheaves under simulated operating conditions is disclosed. The testing apparatus is capable of simulating many conditions under which wire ropes and sheaves are used in actual practice with cranes or the like including adjustments for varying rope tension, rope speed, sheave speed, sheave off-lead angles relative to the rope and to allow reverse bending of the rope. Sheaves of different diameter and different rope size and materials may be tested.

Abstract: A snap together display badge intended to be worn on a person's clothing as a name badge, display button or the like. An open frame equipped with front and rear ridges receives a transparent cover, the display material, and a backplate through the rear, the cover abutting the front ridges and the backplate passing interferingly by the rear ridge. An S-shaped wire clasp is detachably affixed to the backplate by means of a snap attachment made up of ramp elements and protrusions positioned in paired arrangement about an opening in the backplate and a bridge element traversing the opening. The S-shaped body of the clasp is received by the supports of the bridge when the ends of the clasp body are passed over the ramp elements and into position between the protrusion and ramp of each of the pairs thereof.
