  • Patent number: 11808738
    Abstract: A support jig for use with a testing machine applying loads, the support jig includes a frame and a pair of spaced apart supports joined to the frame to provide an alignment axis. Each support is configured to releasably hold a test specimen holder on the alignment axis in a fixed spatial relationship with ends of the test specimen holders mountable to the test machine facing in opposite directions. A test specimen support is located between the holders holds the test specimen on the alignment axis so that the holders can be attached to the test specimen. The support jig allows the holders to be easily and correctly attached to the test specimen so as to maintain alignment of the holders and the test specimen on the alignment axis. The support jig also maintains the fixed spatial relationship of the holders and test specimen while the holders are mounted to the test machine.

  • Publication number: 20220128440
    Abstract: A support jig for use with a testing machine applying tensile loads, the support jig includes a frame and a pair of spaced apart supports joined to the frame to provide an alignment axis. Each support is configured to releasably hold a test specimen holder on the alignment axis in a fixed spatial relationship with ends of the test specimen holders mountable to the test machine facing in opposite directions. A method of using the support jig to remotely mount the test specimen to the test specimen holders from the test machine, and then using the support jig to maintain the fixed special relationship while the test specimen holders are mounted to the test machine is also provided.
