Abstract: A machine for rotary driving screw anchors into underlying ground and related. The machine has a mast with a rotary driver and a mandrel driver oriented on a common axis. The mandrel driver passes a mandrel through the rotary driver and the screw anchor to allow the mandrel to be actuated ahead of the screw anchor while the rotary driver drives the screw anchor into the ground. Alternatively, the mandrel driver may also drive a hammering drill through the screw anchor to clear a path ahead of it through subsurface rocks.

Abstract: A foundation system for manufactured homes, prefabricated houses, and other structures. Multiple screw anchors are driven into the ground at the desired location of the structure. Preformed grade bars may be placed over the screw anchors to provide a modular foundation without pouring concrete or digging footers. Alternatively, adapters may be attached to one or more of the driven screw anchors to provide a pedestal to receive the grade bar or prefabricated sections of concrete.

Abstract: A quick release apparatus mounted on or within the rear bumper of an automotive vehicle for releasing a spare tire located behind the rear wheels and subjacent the undercarriage includes a winch assembly that includes a drum housing a cable coiled upon a rotatable spoke extending through drum with the spare tire resting on and supported by a crossbar and the distal cable end extending through the center of the tire for attachment to the crossbar with the winch assembly also including a pivotal handle having a winch key and a release button so that setting the winch key disengages a ratchet mechanism mounted within the drum and interconnected to the spoke whereupon pressing the release button actuates the unwinding of the cable and the lowering of the spare tire.
