Having come to this conclusion, I triedan arrangement as follows: A three-way valve; that is, a valve which hadthree openings, was located in the cabso as to be handy for the engineer tooperate. From one of the openings apipe connection was made to the mainreservoir pressure, and from another a.

In operating, the engineerclosed this valve by placing his foot onthe stem, just before releasing, and whensufficient time had elapsed for the rearbrakes to release, would permit the driverbrake to release by moving his foot offthe stem of the valve. pipe connection was made to the exhaustport of the driver brake triple valve, andthe third opening was left open to theatmosphere. With the valve in normalposition communication is closed fromthe main reservoir, and open from theexhaust port of the triple to the atmos-phere. In this position there is no in-terference with the release. Pressure July, 1903.
