Abstract

An apparatus for measuring tension in cables or chains comprises a unitary structure which may be entirely formed by welding and bending operations. An elongated resiliently deformable rod has its opposed ends bent laterally in opposite directions into hook-shaped formations to engage a section of a cable in which the tension is to be measured, causing the cable to assume a non-linear, generally helical configuration when the apparatus is assembled thereto. An adjustable height pad may be attached to the center of the bar to engage the cable and increase its helical angle. An indicator bar, having indications provided thereon, is disposed in generally radial relationship to the rod adjacent one end thereof. A cantilever pointer has one end welded to the rod remote from the indicating bar and the pointed end disposed adjacent the indicating bar. As tension is applied to the cable, the rod is bent in a longitudinal arc and the pointed end of the cantilever pointer moves along the indicating bar to indicate the degree of tension applied to the cable.
