Abstract: A blank, having a pair of parallel bushing forming strips that are intermediately connected by a web, is formed from stock. The blank is bent and curled in a progressive die to form a bushing link that includes a pair of cylindrical bushings integral with the web. Rollers can be slipped longitudinally over the bushing ends opposite from the web and an inside plate is welded to the bushing ends to form a roller link. Such roller links are alternately arranged with pin-links to form a roller chain. A bushing chain can be formed in essentially the same manner as the roller chain by omitting the rollers from the bushing links.

Abstract: A motor vehicle has an enclosed battery storage compartment with a door separating the compartment from an adjacent support surface that has been roughened to reduce slippage of persons stepping thereon. A battery holder has a mounting base in the compartment and a battery cell support tray mounted on wheels for rolling between a position on top of the mounting base, where the battery cells are housed, and a position on the surface, where the battery cells are inspected and serviced. Mounted to the tray is a handle having a horizontally extending grip portion for grasping to move the handle or tray and a vertical projecting lock portion for engaging a keeper, mounted on the mounting base, to lock the tray in a stationary position. When the handle is in a tray locking position, the grip portion of the handle extends adjacent the tray and the compartment door can be closed, retaining the handle in its locked position.
