US Patent 10344538 Support clamp

A clamp for supporting an apparatus, such as a pump, a motor, or other mechanism to be lowered into a drill hole includes two coupling halves connected together using a bolts and nuts. Each half has a semicircular interior that forms a cylinder when two halves are connected to each other. Protrusions in the semi-circular interiors mate with indentations in the pump wall to support the pump. Chains or other devices attach to eyelet bolts or to a pivoting bail affixed on top of the coupling halves so that the clamp and the pump may be raised or lowered by external lifting apparatus.
