APPARATUS FOR TESTING THE DEFORMATION UNDER LOAD OF RUBBER OR OTHER ELASTICALLY DEFORMABLE MATERIALS

摘要

An apparatus for testing the deformation under load of elastic materials has a base and a pressure plate between which a specimen may be clamped. An initial deformation is applied to the specimen by a screw which coacts with the pressure plate. The screw also provides one of a pair of electrical contacts, the other contact moving with the pressure plate. An external load applied to the pressure plate to further deform the specimen breaks an electrical circuit to provide a reading of this further load. Provision is made for releasing the load applied by the screw and for resetting the screw so as to apply the same initial load.
