ABSTRACT:
A torque measuring device designed for convenient use intermediate a ratchet wrench and socket is provided with a pair of oppositely disposed compression springs that are so housed within the first of a pair of complementary plates as to yield to a rotational force applied in either direction, the compressible yield of one of the springs as the ratchet wrench is turned in a given direction producing a lag in the rotation of the second of the plates which is measured in terms of torque by means of a pointer and a calibrated scale, the convenient substitution of the springs with selected springs of varying tension permitting the wide range of torque measurement including measurement in foot pounds, inch pounds, and metric.
