ABSTRACT:
A chain drive which has an automatic chain tension adjustor. The chain adjustor has a housing cover with a cover head suitable for being turned with a ratchet for transferring torque to an adjacent motor spring.

A chain adjustor screw within the shaft is urged by the motor spring through the shaft and housing against the chain adjustor arm. The arm pushes the chain and reduces slack in the chain.
