Abstract: A jam proof lug nut and socket wrench combination. A lug nut has a polygonal shaped tapered main body. The tapered outer surfaces of the main body are arranged at an angle relative to the nut longitudinal axis greater than the interior polygonal surfaces of the socket wrench relative to its axis of rotation.

Abstract: A band-saw-cutting system for cutting sections from a work in a substantially continuous, automated manner. The system includes a work carrier adapted to support one or more pieces of work and to be reciprocated to carry the work from a home position to a forward position in a cutting stroke to cut the work and back to the home position in a return stroke. The system includes blade-moving means for automatically moving the blade out of the cutting plane of the blade during each return stroke such that the work will not contact and rub against the blade during the return stroke, and for moving the blade back into the cutting plane prior to the initiation of the next cutting stroke. The system further includes means for automatically moving the work transversely against an adjustable fence to position the work relative to the cutting plane to cut desired thicknesses from the work during each cutting stroke.
