DEVICE FOR BABBITTING CROSSHEAD SHOES. efficient machine for cutting out gaskets from old hose has beenconstructed and is operated by the roundhouse tool man in hisspare time. The air cylinder is 12 x 14 in. and is limited to a 3/2in. stroke, so that a comparatively small amount of air is con-sumed. The cutters are made of tool steel, as shown, and acopper plate is fastened to the top cross-bar back of the gas-ket, to reduce the liability of injuring them. The bar, whichpasses through a slot in the piston rod, limits its stroke andforces two pins upward, as the cutter drops back to the positionshown in the illustration, pressing the gasket out. Where cut-ters of this type are struck with a hammer or sledge in cuttinggaskets they are easily broken on account of the unequal pres-sure on the cutting edges. With this press there has thus farbeen no breakage and the life of the cutter seems to be Grease for Driving «.-The device used for. DEVICE FOR MOULDING GREASE FOR DRIVING BOX CELLARS. April. 1900. AMERICAN ENGINEER AND RAILROAD JOURNAL !4J moulding the grease for driving uo> cellars is illustrated both bya photo and a sketch. The bottom of the mould is held in placeby the two latches and the grease is put in through the hole atthe front. Air is then allowed to enter the u x 12 in. cylinderand the plate at the end of the piston rod presses the grease tothe shape shown in the illustration. The former method ofpounding the grease into shape by hand was slow and Crosshead Shoes.—The old practice was to till theshoes with babbitt, over blocks slightly smaller than the guide,and plane them out to size. With the device illustrated the shoe,
