Abstract: A machine for installing a giant tire on a one-piece rim includes a force unit, a guide cone having large and small ends, the former of which connects with the rim, and a clamping unit for holding the guide cone with the rim attached to its large end in a firm position against the force unit. The force unit has an upright frame and maneuvering cylinders positioned on the frame so as to be located generally around the small end of the cone when the cone is against the force unit. The small end of the cone is small enough to fit into the center of the tire, while the large end is about the same diameter as the outside diameter of the flanges on the rim so that the large end forms a gentle approach over the rim flange against which it is positioned. A portion of the guide cone behind the large end is cut away to form a relief which opens downwardly. The tire to be installed on the rim is first placed over the small end of the cone and the small end is clamped against the force unit.

Abstract: An alignment clamp is disclosed for uses such as welding adjacent plates. The clamp utilizes a strap which passes through a gap between the adjacent plates. The strap is attached at one end by a plate like clamp member which is to be located on one side of the welded plates. The strap connects to a clamp member on the opposite side. The second clamp member is located above the plate to be clamped. It is on freely movable guide posts spaced apart from a bearing plate. A tapered wedge is driven between the second clamp member and the bearing plate. The tapered wedge separates the two and pulls the strap taut. When it is taut, it levels and temporarily connects the adjacent plates held by the clamp to permit welding in the gap between the adjacent plates, and is thereafter disassembled to enable the removal of the clamp to close the gap by welding.

Abstract: A pair of substantially flat rectangular fusible links is constructed from progressive dies by partially cutting them from sheet metal stock as blanks, flanging edges on the parts and including the forming of triangular camming surfaces on such flanges, and then shearing the parts from the stock. Thereafter, the links are fluxed and soldered together and are held in interested complementary relation. It is characteristic of the links that there are no voids or discontinuities in the joined surfaces and into which flux will not flow; the interfacing triangular cam surfaces insure a clean breaking apart of the links once the eutectic temperature is reached because any longitudinal sliding movement of the links biases them laterally apart under the camming action to insure a complete break-away of the confronting soldered surfaces.
