Definitions
- rIhe waste-pipe b communicates ⁇ directly with the escape-port a.V
- aT-pipe, b On the outerend of it is aT-pipe, b", in one end of which I screw ⁇ the nozzle c, which, by a pipe, c', communicates with either the steam-boiler for the injection of steam, or with the air-reservoir .described in my'patent of 13th April, 1869, for the injection of air.
- the arrangement of the conical nozzle c with reference tothe waste-pipe may be varied at pleasure, according to the known lawsgov-V erniug the operation of such devices.
- the nozzle ⁇ c may be arranged directly in vthe waste-pipe b, but discharging in the direction ofthe ontwardflow of air.
- the cock A When it is desired' to let ofi' the brakes the cock A is turned to the position shown. A jet of steam .or compressed air, preferably the former, is turned into thepipe c", which, passing out through the nozzle. c, exhausts the air from the brake-cylinder G through the communicating pi-pes and ports, and almost instantaneously lets off the brakes.
- the steam Siphon-pump may be otherwise combined with the brake-cylinder so as to apply or put on the brakes by means ofA the ex-A haustion of the air from the cylinder back ot' the pistoni. c., on the side toward which it moves 'in applying the brakesinstead ofthe compression of the air inthe cylinder in front ofthe piston.l
- valve m seats itself by its ownweight; but itmay be A plaeed in any l other desired position, and be seated byv a spring or other equivalent device.
- avalve may be arranged in any of the pipes b df. -As thus arranged it permits the outflow of air, but prevents the inflow of steam when the reaction ofatmospheric pressure takes place.
- a steam or ,air dischargingnozzle arranged in the air-outow pipe of a oar-brake cylinder, discharging in the direction of the outflow of air from the cylinder, and in ,com-Y bination with such cylinder, substantially as described.
