. Locomotive engineering : a practical journal of railway motive power and rolling stock . and unless the auto-matic car coupler patentee looks closely tohis laurels he will find himself severelyjostled by this erstwhile inventor crowd-ing into first place. The latest addition tothe already large family of angle cocks,herewith illustrated, is the product of Bedell, of Jackson, Mich. Theoperation of the device is as follows: When the valve is open, so that thebrakes can be governed by the engineer. the air is entirely shut off from the air, after passing through the holesDi and Ei, passes into the holes H and11, and raises the valves Hi and Ii, andthen to the pipe Bi and to the alarm, thuswarning the trainmen that the valve isbeing meddled with, and at the same timedefinitely locating which one it is, as eachvalve has its own alarm. The valves Hi11 serve to prevent the air backing up incase the pressure comes from only oneside. When switching or any other cause re-quires the hose to be parted, and it is notdesired that the shall set, the small. Fig. 1 1XU the holes Da and E2 are covered by thebushing G, so that no air escapes to thewhistle; but when the plug is turned, soas to partially or entirely shut off the airin the main pipes, the holes D2 and E2come into the opening g, which extendsthrough the bushing G. When in thisposition the air passes through the holesD2 and E2, down through the cavities orspaces D and E, and from there outthrough their respective openings Diand Ei. Now. in the bushing G are thegrooves Gi and G2, leading to the holescorresponding to those marked Di andEi in Fig. 3. This allows the air to passthrough the openings in the bushing be-fore the holes in the plug and the corre-sponding ones in the bushing come di-rectly opposite each other. This is sothat the alarm will begin to sound before cock under the whistle should be closedto prevent the escape of pressure. (Waiving the discussion of whether suchangle cocks
