Fig. 3 is asectional view on line X X of Fig. 4 is a sectional view on line 5 5 ofFig. 2. Fig. 5 is a view showing the ap-plication of the invention to a train-line,and Fig. 6 represents diagrams showingthe various service positions. FUj. .3 Jiaitway J Lt>cvma;tv4 t:n^.nteriii^ In the drawings the numeral I desig-nates the shell or casing having a taperedr>])ening 2 therethrough, and air-pass-ages or ports 3 and 4 communicating withthe said opening and train-line connec-tions or ends 5, and a similar port 6 com-municating with said opening and triplevalve end 7. A tapered plug-valve 8 is fitted intothe tapered opening of the casing and isheld in position by a spring 9 and capTO. The plug-valve is provided with aside or cut-away part 11. straight-awaypart 12, and part 13 branching from saidstraight-away part, which parts are. y iloiilCl:^ J i<«flie £«rfM7 adapted to register with the parts in thecasing and with the dead-air ports 14. At the upper end of the casing is foundfour stop-notches 15, and to the top oftlie plug is attached a handle 16, which isprovided with a spring catch 17 to en-gage said stop notches. Said spring andnotches serve to indicate the position andretain the cock in such position. In practice the train-line is connectedto the ends 5 and the pipe leading to thetriple valve to the end 7. If it is desiredto let air from the train-line on the leftto the triple valve, the cock is turnedinto position shown at Figs, i, 2, 3 or 4and at B of Fig. 6. To let air from thetrain-line into triple valve at right, thecock is turned one quarter, as at C,Fig. 6. From both cars to triple th< cock isas at D, Fig. 6, and for straight-awaytrain-line as at A, Fig. 6, the stop-spring Fia. s
