The Street railway journal . of the wagon when thetower is in the position shown in the accompanying are a number of details in connection with this wagonwhich are worth studying on the part of the superintendentof overhead construction. THE HARRISBURG FOUNDRY & MACHINE WORKSOne of the units of the Intramural power plant in the Ma-chinery Building is driven by a Harrisburg Foundry & MachineWorks Fleming, 4-valve, tandem, compound, automatic engineof 600 hp. This engine operates at the high speed of 150r. p. m., but is, nevertheless, very smooth in operation, andalthough it is located near Corli:s engines having much lowerrotative speeds, the high speed of the engine would not attractthe attention of the casual observer. The engine has cylinders15-in. and 403^-in. x 26-in. stroke. The governor is located onthe shaft and acts on one of the eccentrics. There are threeeccentrics. One of these eccentrics is controlled by the gov-ernor, and, thererore, controls the point of cut-off of the high-. OF THE HARRISBURG FOUNDRY AND MACHINEWORKS pressure cylinder. The second eccentric is fixed on the shaft,and controls inlet valves of the low-pressure cylinder. Theseinlet valves, therefore, have the point of cut-off fixed. The thirdeccentric opens and closes the exhaust ports, four in each cylin-der. The engine is automatically lubricated. The crank chainher is closed and partly filled with oil, the crank pin and guiderods are lubricated by the splash of oil in the crank chamber, Near the top of the crank chamber, above the lever and themain bearing, is a trough which receives some of the oil splashand delivers it by gravity to the main bearing. THE AULTMAN & TAYLOR MACHINERY COMPANYThe exhibit of the Aultman & Taylor Machinery Companyswater-tube boilers and chain grate stokers consists of eight500-hp boilers, built to carry 250 lbs. steam pressure. Eachboler contains 5080 sq. ft. of heating surface, and is equipped
