Fatigue Testing Apparatus.
Abstract
This invention relates generally to the fatigue testing of wire by cyclic displacement under tension while immersed in a test medium. A pair of wire specimens supported within a transparent frame along direction changing paths established by two sets of pulleys are interconnected between a common powered rotor and a pair of wire tensioning weights protectively enclosed by plastic sheathings. The wire specimens are simultaneously and cyclically displaced along said paths through test medium during a testing operation terminated in response to rupture detected by sensing switches engaged by the weights. Patent applications.
