Abstract: The present invention is a jack assembly having a first and second upper bracket pivotally connected to a support member and each having at least one strengthening bead and at least one rolled edge. A first lower bracket is pivotally connected to the first upper bracket using a non-threaded trunnion and a bearing through which a threaded rod extends. A second lower bracket is pivotally connected to the second upper bracket using a threaded trunnion through which the threaded rod also extends. The brackets are tapered for strength. The first and second lower brackets are pivotally connected to a base having an enclosed keyhole orifice for storage of the jack assembly. At least one strengthening flange is formed in both the first and second lower bracket.

Abstract: A progressive die apparatus and method for cold forming weld adapters. A progressive die apparatus, preferably having at least four working stations and several idle stations, is used to form, weld adapters from rectangular bar stock having a thickness of at least about 3/8 inch. Plain-carbon steel bar stock material or other weldable metal material is successively fed through the progressive die apparatus, which is preferably installed in a knuckle-joint power press.
