ABSTRACT:
A load measuring gage generally shaped like a conventional split ring washer. In the center opening of the gage a shaft, which mounts the device whose load is to be measured, may extend through the washer. The opening for the washer is cut diagonally so that the loading and unloading forces acting upon it are collinear thereby reducing friction that resist its opening and closing to a minimum. This is accomplished by orienting the angle between the split ring surface and adjacent bearing surface to be between 50.degree. and 62.degree.. A force indicating pointer and scale can be attached to the washer to inform observers visually of variations in the force applied to the gage. In this way if the tension on a mine rock bolt is being measured, observers may safely be informed of the force on the in situ bolt from a distance.
