Abstract: An automotive framing system is disclosed for positioning an underbody component with at least two body side components wherein the body side components are positioned on top of the underbody component to form a body preassembly. The system includes a conveyor for sequentially moving body preassemblies to a predetermined assembly station. At least two frames are selectively positioned at the assembly station and each frame includes structural beams extending over and around the sides of a body preassembly position at the assembly station. At least one lifting rail is vertically slidably mounted to each frame and movable between an upper and a lower position. In its upper position, one or more locators on the lifting rail register with locator receptors on the underbody component so that, as the lifting rail moves from its lower and to its upper position, the lifting rail elevates the underbody component from the conveyor to a predetermined position.

Abstract: Durable knockdown flat sheet metal component birdhouse having slidable flanged edge assembly connections and flat wood panel interior liners. The assembly connections include U-shaped folded 180.degree. flanges extending in the plane of sheet metal panels slidably engaging mating 90.degree. flanges on adjacent panels to provide an integrated self-supporting box construction free of required supplemental fastening means. A plurality of such birdhouses mounted on a horizontal rod serve as equivalent to a multiple compartment "Martin" type birdhouse.
