It is a ten-wheel engine built for freight service, and is of the two- The United States metallic packing is used for the valve-stems. The exhaust nozzle is single and is 4^ in. in smoke-stack is 13^ in. inside diameter. The especial feature of this engine as a compound isthe use of two cylinders, the intermediate receiver and theintercepting valve. The ratio of the high to the low-press-ure cylinder is i : ; of the high-pressure cylinder tothe receiver i 1 The diameter of the intercepting valveis 7 in., and the smallest diameter of the reducing valve is3 in. ; the pipe supplying live steam to the reducing valveis 2j in. The reducing valve, the most important feature, isPlayers patent. This is shown in detail in figs. 18-27,which are taken from the patent drawings. In these TWO-CYLINDER COMPOUND LOCOMOTIVE. .BUILT BYjTHE BROOKS LOCOMOTIVE , N. Y. cylinder compound type. The general design is shown bythe photograph. To give first a general description, the boiler is of thewagon-top type, built for a working pressure of 180 lbs ,the material used being steel. The plates are ^y in., ^ y\ in. ; the horizontal seams have lap joints and areqradruple riveted, and the circumferential seams aredouble riveted. The barrel is 52 in. in diameter, andthere are 186 tubes 2 in. m diameter and 12 ft. long. Thefire-box is 34 in. wide inside and 8 ft. long ; the crown-sheet is supported by crown bars 5 X i in. in section, andwelded together at the ends. Feed-water is supplied bytwo No. 8 Monitor injectors. The water-space around thefire-box is 4 in. in front, 3 in. at the sides and back. The driving-wheels are 56 in. in diameter, and the driv-ing-axles have 7 X 8-in. journals. The main crank-pinsare 4J X 6 in. ; t
