Abstract: A bus suspension mating fixture assembly having a bus body overhead support assembly and a bus suspension shuttle assembly. The bus body overhead assembly comprises an elongated framework having a first pair of laterally spaced upright side beams connected together adjacent their tops by a transverse beam and a second pair of laterally spaced upright side beams connected together adjacent their tops by a transverse beam, and a pair of laterally spaced longitudinal beams that have their opposite ends connected to the upright side beams adjacent their tops. A pair of laterally spaced longitudinal overhead support rails are supported from the top of the bus body overhead support assembly and the overhead support rail unit can be raised and lowered throughout a predetermined range.

Abstract: Apparatus for assembling a wall module from a plurality of stretched sheets of metal laterally spaced apart by a skeletal frame with the interior of the wall module to be later filled with structural foamed plastic. The apparatus has a first and a second elongated sheet metal stretcher assembly, a pair of tower assemblies for supporting the first elongated sheet metal stretcher assembly vertically above the second elongated sheet metal stretcher assembly, and a plurality of jack screw assemblies for moving the first elongated sheet metal stretcher assembly vertically toward or away from the second elongated sheet metal stretcher assembly. Both of the elongated sheet metal stretcher assemblies have sheet metal clamping jaws longitudinally fixedly mounted adjacent one of their ends and longitudinally movable sheet metal clamping jaws mounted adjacent their other end.

Abstract: Apparatus for holding hollow wall panels while they are filled with foamed plastic having a base, a lower platen, an upper platen, and a plurality of inflatable hoses. The base has a top pressure surface upon which the inflatable hoses are positioned. As fluid under pressure is released into the inflatable hoses, the upper surface of the hoses contact the bottom pressure surface of the lower platen to lift the lower platen upwardly. The hollow wall panels are supported by a plurality of longitudinally spaced roller support brackets that extend downwardly from the opposite sides of the upper platen. As the inflatable hoses are pressurized, the upward travel of the lower platen will cause its top pressure surface to contact the bottom of the hollow wall panels and hold them in rigid engagement against the bottom pressure surface of the upper platen. When the hollow wall panel is thus positioned, it is filled with foamed plastic.

Abstract: A pierce rivet machine for simultaneously pierce riveting sheets of material to the opposing flanges of a channel shaped member having a first and a second pierce rivet driver, a first and a second pierce rivet holder for respectively holding rivets for said first and second pierce rivet drivers, and a first and a second anvil each respectively positioned to function in conjunction with the operation of said first and second pierce rivet drivers. The first and second pierce rivet drivers are positioned diametrically opposed to each other. A drive rod supports each pierce rivet driver and attached to the end of the drive rod is a link member and bellcrank for driving the drive rod along an axial reciprocating path. A tie bar has its ends pivotally attached to the bellcranks causing the drive rods to be simultaneously actuated. One of the bellcranks has its end pivotally attached to an air cylinder motor that operates the machine.
