ABSTRACT:
The invention is directed to a ratchet or hold-down mechanism for a motor which is pivotally connected to a base of a compressor attached to an air receiving tank. The compressor is provided with a base having a pair of legs at one end which terminate at resilient pads resting on the tank. The motor is attached to the compressor base adjacent the legs for limited pivotal movement toward and away from the compressor. A ratchet or hold-down mechanism is provided between the motor and the compressor base to restrict pivotal movement of the motor toward the compressor while allowing the motor to pivot away from the compressor to increase the tension on a belt connected therebetween. The ratchet mechanism maintains tension on the belt in the event that the portable air compressor is picked up by the motor or is accidently tipped on its side. In addition, the ratchet mechanism maintains a minimum tension on the belt during operation of the motor.
