Under present conditions, if a slight leakdevelops due to a defective thread, where an angle cock makeson to the train line, a new thread cannot be cut without re- moving clamps, unscrewing the angle cock, disconnectingpipe coupling somewhere under the car and removing a sec-tion of pipe to the shop to be rethreaded. The result of thiscondition is to put a premium on careless inspection since itis the inevitable tendency to neglect to report small leaks. Beaver No. 4 Ratchet Die Stock which are difficult to repair. The ratchet die stock will enablethese repairs to be made easily and thus assist in keepingtrain lines tight. Cone Pulley Gap Bed Lathe AN addition to the line of engine lathes manufacturedby the Shepard Lathe Company, Rising Sun, Ind.,is the 12 in. gap bed lathe, illustrated. This machineis of particular interest to railroad machine shop men be-cause widely varying diameters have to be turned in railroadshop work and it is a great convenience to be able to dothis work on one machine. On account of the gap featurethe lathe, illustrated, can swing 19 in. for lengths 5 in. infront of the face plate and thus the range of work whichcan be handled is greatly increased. In addition, the gapfeature makes it possible to turn such work as air compressorpiston rods on a relatively light high speed machine withoutremoving the pistons and with a considerable saving in power. The bed of the lathe is thoro
