Abstract: A method and apparatus for finishing pistons (10) and the like from foundry-turned castings during one clamping operation to provide enhanced manufacturing productivity. Separate boring and turning modules (34, 24) of the apparatus are mounted on a primary base (18) and a grooving module (54) is mounted on a secondary base (72). The modules automatically groove the ring grooves (11), turn the complex shape of the skirt (15) and bore the wrist pin bore (13) through an ordered sequence of manufacturing steps. The piston stock is mounted for rotation on headstock and tailstock assemblies (82, 84). These assemblies are carried on the secondary base (72) which is slidably mounted on the primary base for movement into operative position with respect to the boring and turning modules according to the ordered sequence. The method and system improve piston quality while reducing manufacturing costs including saving factory floor space.

Abstract: Pallets of substantially unitary construction for transporting materials with a handtruck having a front carrying blade, comprising a deck, at least two upwardly extending sides and legs at each corner of the deck extending downwardly approximately one-half to an inch and a half from said deck. The deck preferably contains openings for hand placement for removing merchandise from the pallets. The pallets permit the handling of a plurality of cases containing merchandise stacked one on the other with a handtruck without concern of tipping of the plurality of cases. Additionally, merchandise can be displayed in the pallets without detraction from the merchandise on display.
