The springs are brought close up tothe faces of the inner pedestal jaws and the spring centersare about 10 inches from the centers of the axles, whereas inusual construction this dimension is from 20 to 22 inches. Thisconstruction also aims to prevent the tilt of the truck framesupon the application of the brakes, the equalizers being passedthrough the boxes and held by saddles around the convenience in removing the wheels the outer pedestaljaws are hinged so that it is not necessary to raise the truck. A number of these trucks are in service, most of them beingin Kansas City. Mo. 60 AMERICAN ENGINEER AND RAILROAD JOURNAL. 125-H. p. Westinghouse Gas Engine, Direct the Power House of the H. K. Porter Pittsburgh. A SUCCESSFUL GAS-ENGINE POWER PLANT. other mechanism being starting of one of theseengines is a simple and easymatter, which is accomplishedIjy the use of compressed engine is given a couple ofturns by the air cylinder, andwhen a charge of gas and airhas been drawn in, compressedand exploded, the task is ac-complished. The air supply Isfurnished by a small Westing-house compressor, the air beingstored in iron tanks, tested un-der a pressure of 250 pounds persquare inch. The tanks are sup-plied with a pressure gaugeand a safety valve to guardagainst overcharging, and theyare shipped charged to 160pounds pressure for starting theengine the first time. Whenthe plant is once in operationI he compressor is run for a fewminutes each day by a beltfrom a convenient pulley, eitheron the engine itself or onthe line shaft, mai
