It isclaimed for this equipment that the maintenance cost and theconsumption of steam and of oil are low and that the absenceof grease cups and packing reduces materially the attentionwhich is required at the engine terminals. EXPANSION JOINT WITH ACROSSHEAD GUIDE An joint having a crosshead and guide, adaptedto all service on high or low pressure water, oil, gas orsteam lines, has been tested for several years and is nowbeing manufactured and sold by the Ross Heater & Manu-facturing Company, Buffalo, N. Y. It is claimed for thiscrosshead guided joint that the sleeve is held in perfectalinement and that the weight of the pipe line is relievedfrom the sleeve and packing, thus preventing excessive wear. Ross Crosshead Guided Expansion Joint on these parts. The main casting is divided in two parts,which are connected by a heavy flange and bolts. The mov-ing elements consist of a long sleeve made steam-tight bya stuffing box and gland. The sleeve is supported at theouter end by companion flanges, which are machined onthe outer surfaces and slide in the guide, the internal surfaceof which is also machined. Stops are provided on theguide to prevent the crosshead l>eing drawn out of the casingand thus breaking the joint. .\\\ the parts are substantially constructed and are readilyaccessible by removing the casing. The packing space ofthe stuffing box is long and is adapted to the use of anykind of metallic or fibrous packing. The sleeve is madeof bronze and for pressures up to 150 lb. all other partsare made of semi-steel; for higher pressures cast steel isused. The sleeves are made in two types, one having a freetravel of 4 in. and the other of 8 in. These
