When theengineer wants to release his brakes heputs 4 pounds in the train pipe and keepsit on about 10 seconds. If he should findsome brakes stuck he would hold the 4pounds pressure longer. Figure i would make a good retainingvalve for the driving brake and tenderbrake. Yours truly, Tony Silvene. Victoria, B. C. An Improved Hand Brake.

The passage, 8, is provided in the nip-ple and communicates with the brake cyl-inder, but extends vertically through the pipe is reduced and the upward pressureon the piston E will be about andthe downward pressure on the piston D, plus 20 pounds, the pressure of thespring, or a total of pounds. It willbe seen that the downward pressure ex-ceeds the upward, hence the pistons willmove downward and close the passages ly in a novel means of mounting the brake-staff whereby it may be swung from avertical to a horizontal position withoutthrowing it out of operative connectionwith the brakes.
