386 the frame from being carried into the cylinder. The cylinder is iron, cast in one piece with the valve chest. Both are thoroughly insulated with nonheat conducting material and covered with a lagging of planished steel. The cylin- der is equipped with relief valves of large diameter, which may be adjusted to open at any desired 'pressure. These guard against damage due to water coming over with the steam. The valve is of the piston type and operates in a renewable bushing, which forms the valve ports. The valve is connected by means of the valve stem, slide eccentric rod and eccentric strap to the eccentric attached directly to the governor. All pins and rods are open-hearth steel and the bearing pins are hardened and ground. The engine is equipped with an in- ertia governor. This governor is placed in a heavy flywheel and is capable of close regulation keeping the -variation between no load and full load as low as. /1.5' per cent. The piston is cast iron cored for lightness and fitted with cast iron snap packing rings. It is pressed to a taper fit on the piston rod, and is further secured by a nut pinned to the rod. Both the connecting rod and the piston rod, are open-hearth forged © steel, €ach in a single forging. The crank pin end of the connecting rod is pro- vided with malleable iron, marine type boxes, and the crosshead end is fitted with brass boxes of the same design. The crankshaft is open-hearth steel made in a single forging, machined all over and carefully fitted with balancing counterweights secured to the webs, the crank pn being hardened and ac- curately ground to size. The lubricating system is automatic, continuous and self-contained, requir- ing no independent tank or reservoir. In engines having gravity type lubri- cation, the ov is pumped from the reservoir in the base by a chain driven _rotary pump which is entirely sub- merged in the oil, to the upper reser- voir cast in the top of the frame. From here it flows by gravity through brass pipes to the various' bearing surfaces requiring oil, then back to the reservoir in the base where it is strained and pumped again.. Where a forced feed system of lubrication is furnished, the submerged pump forces the oil under pressure through brass pipes direct to all parts requiring lubri- ation. Tie: of then drains back. to the base, where it is strained and again forced through the system. An oil well level gage is supplied, attached to the outside of the base. The Westinghouse type generators forming part of these sets are especial- MARINE REVIEW ly constructed to meet the require- ments of marine service. The frame is forged open-hearth steel. The _ bear- ing on the generator is a solid steel shell, babbitt lined and so constructed that no leakage of oil will occur with listing of the ship. The armature coils are.so constructed that no cross overs on edge occur, Business Changes The New York office of. the Theo. A.

Both armature and ficld windings are impreg- nated with a special compound for re- sisting the moisture and' salt atmos- phere found in marine service. One of the fundamental ideas of the design is the open, well ventilated con- mum. 'river and Jefferson avenue bridge, August, 1921 struction. The air can circulate freely through the generator, coming in thorough contact with all internal parts and thus eliminating the possibility of internal hot spots which in time could not fail to have a damaging effect on the insulation. Sparkless commutation results from the application of commutating poles and consequently the wear of commu- tator and brushes is reduced to a' mini- This is especially"so since the speed of these sets is relatively low. The brush pos:tion is fixed before the set leaves the factory and never re- quires any adjustment. Noncorrosive material is used for brush holders and all parts which might be affected by moisture.

New Trade Publications STEAM TABLES--The Wheeler Condenser & Engineering Co., Carteret, N. J., announces the publication of the 1921 edition of "Steam Tables for Condenser Work." This is the sixth edition. The tables are in handbook form, pocket _ size. The properties of saturated steam are tabulated from 29.8-inch vacuum to atmospheric pressure in increments of tenths of an inch referred to a 30-inch barometer. The values were calculated for this book by Pro- fessor Marks. Above atmospheric pressure the increments are in pounds gage. The book ex- plains how measurements are made by means of the mercury column and barometer, and gives constants and tables for making corrections. Corrections for the thermal expansion of merf- cury, for the relative expansion of mercury and brass scale, and other corrections are included. Engineering Co., Hippodrome building, { ; A '
