Abstract
The arm wrestling device of the present invention utilizes a torsional spring attached to conventional collars with a shaft running through and extending beyond the length of the spring. The shaft is mounted in pivotal supports which allow the shaft to rotate counterclockwise when force is applied to an attached level arm. The clockwise rotation of the shaft is limited by an arm stop so that the lever arm does not pass a vertical position. A pointer connected to the opposite end of the shaft from the lever arm reads on a calibrated scale the units of torque developed in the spring when the force is applied to the arm. This arm wrestling device is for use by one person and simulates arm wrestling between two people.
