haye invented a new Automatic Air-Couplingfpevice', of which the following is a speci V; ,juriction,with each other on the" principle of {r ghtand left, which shoes contain two gaskets, forming air-tight joint, shoes held in is place by springs, air-supply through shoes, being controlled by leversfrom side of car,

which levers act in conjunction with present trated in the coupling-lever; and the objects of cur invention are, first, to provide an automatic aircoupler second, to afford facilities for control of air from side of car. We attain these objects by means of the mechanism illusaccompanying drawings; in which--- i Figure I is a view from the under side. of the coupling. Fig. II is a side view" of the entire "device.
