Patent ID: 7513168

Claim:
A tensile strength testing machine comprising: a frame assembly including a crosshead element, a footing element, and at least two column elements engaged with and extending between said crosshead and footing elements and adapted to maintaining said crosshead and footing elements spaced from one another; an arbor assembly mounted to said crosshead element and including an arbor element extending axially slidably through said crosshead element from a first to a second side thereof, a first specimen mounting fixture attached to said arbor element on said first side, a thrust collar element mounted around said arbor element on said second side in a generally axially fixed position relative to said crosshead element, a load imposing flange element adapted to being mounted around said arbor element on said second side in a generally axially fixed location relative to said arbor element and having a plurality of threaded bores extending therethrough, a plurality of jack bolts threadably received in said threaded bores and adapted to bearing axially on said thrust collar element; a load measuring member measuringly associated with said arbor element; a load indicating member indicatingly associated with said load measuring member; and a mounting fixture assembly mounted to said footing element and including a second specimen mounting fixture, said first and second specimen mounting fixtures being adapted to securing a test specimen therebetween in a tensile strength testing configuration.
