Railway mechanical engineer . stroke of the piston,on the cylinder casting, a projection is provided with twoportholes PP and dowels to correspond to the bolt holes inthe face of the flanged rectangular face of the feed valve. The main idea of developing this device was to facilitate the holding of the feed valve in place while the operator waslooking after the test, reading gages, etc., which could notwell be done if the operator had to hold the valve against afitting or lose time tightening and loosening nuts. Y\ ith this device, the operator places the feed valve bolt-ing flange with the bolt holes over the dowels on the tester,thus bringing the ports in the machine and valve in line (apermanent metallic gasket being always on the machine).With the other hand the operator opens a 34~m- ar cocklocated at or near G, this cock being connected to the airpressure system. This piston is then forced outward adistance of 1% in., pushing the cross arm B which in turntakes the two lever clamps DD with it. This causes the. :~C Feed Valves are Readily Clamped on This Device for Testing lower ends of the clamps to press hard against the flange ofthe feed valve and hold it tight enough to form an air-tightjoint, thus holding the feed valve in place while the operatorsubjects it to the usual prescribed test. Upon closing the small valve referred to above, the coiledspring forces the piston back to open position, the exhaustair passing out of a porthole provided for the purpose in thecock or valve. In the meantime the feed valve has beenreleased. This feed valve testing device has proved agreat source of convenience as well as a great saver of timeand money. Henry Fords entrance into the field of steam railway trans-portation, through his acquisition of the Detroit, Toledo & Iron-ton, has aroused a more intense public interest than any othersingle recent event in railroad history, not excepting the adventof federal control at the beginning of 1918.
