Definitions
- the air-outflow or waste pipe I communicatesdirectly with the escape-port c.
- a T-pipe, b On the outer end of it is a T-pipe, b, in one end of which I screw a nozzle, 0, which, by a pipe, 0,- coimnnnicates with either the steam-boiler, for the injection of steam, or with the air-reservoir described in any-patent (if-13th April, 1869, for the injection of air.
- the arrangement of-6o the conical nozzle 0 with reference to the air outflow or waste-pipe may be varied at pleas ure, according to the known laws governing the operation of such devices.
- the nozzle 0 may be arranged directly in the waste-pipe Z1, but discharging in the direction of the outward flow of air.
- the steam siphon pump or ejector may be otherwise combined with the brake-cylinder so as to apply or put on the brakes by means of'go the exhaustion of the air from the cylinder back of the pistoni. a, on the side toward which it moves in applying the brakes-instead of by the compression of the air in the cylinder in front of the piston.
- a pipe, f leading from the t end of the cylinder U toward which it is desired the piston should travel in applying the brakes.
- the valve m seats itself by its own weighhbut it may be. placed in any desired position and be seated by a spring or other equivalent device.
- a valve may be arranged in any of the pipes b (if.
- a ,brake-cyh inder and piston in which air-pressure is applied to the piston both to apply and release the brakes, in one case by means of compressed air as against atmospheric pressure and in the other by means of atmospheric pressure as against a vacuum or partial vacuum, substantially as set forth.
