Abstract: A kit for assembling a housing unit includes packaging for storing and transporting building materials. The building materials are used to assemble the housing unit. The building materials may include a door, windows, beams for forming a frame, each having pre-formed symmetric holes, and sheets of material for forming walls, a roof, and a floor. The building materials also include a plurality of fasteners for connecting the beams to one another and for connecting the door and the sheets to the beams. The building materials also include a squaring strap to ensure that the beams are situated at fixed angles. Some of the building materials may form part of the packaging. The remaining building materials, if any, are included inside the packaging for storage and transport to the desired site for the housing unit.

Abstract: An improved hemming die fixture, used in conjunction with a sheet metal press, is disclosed. The fixture is attachable to the ram, or ram assembly, of a metal press and carries with it a hemming die. The fixture is automatically displacable between working and standby positions. When not in use, the hemming die fixture is placed in a standby position wherein it is placed parallel to the ram of the press, and away from a primary die on the bottom of the ram. When required, the fixture may be actuated to place a hemming die parallel to, and below, the primary die located along the bottom of the ram. The hemming die then coacts with the work table, or second flat hemming die, of the press to form a hem along a longitudinal edge of a piece of sheet metal in a plane other than the plane in which a full bend is first formed along the edge of the sheet metal.
