No more angle cocks cutoff by tramps or other persons, as thisdoes away with angle cocks entirely. The device consists in the combination,with an air-brake coupling-valve havingits stem extended beyond the coupling-head,-of a valve-setting lever having aneccentrically-arranged fulcrum throughwhich it is directly connected with theprojecting portion of the valve-stem tooperate in bearing contact with an outerportion of the coupling-head, so that inone position of said lever the valve will be.

This being true, it follows that the pipetaking steam to the pump should have acontinuous incline from the point where unseated and locked against a closing orseating movement, and in the other posi-tion of the lever the valve will be free toseat automatically when the two coupling-heads are separated.
