Title: Improvements in automatic speed control valve for trains
IPC: B60T7/12
Filed: 1924-04-22
Abstract: 215,341. Otis Automatic Train Control, Inc., (Assignees of Bissell, D. J.). May 1, 1923, [Convention date]. Track apparatus for stopping trains.-In an automatic braking system having a valve 36 which normally connects the air-supply pipe 43 with the train pipe 45, and which may be operated by a track ramp to disconnect the supply and vent the train pipe through a pipe 41 to apply the brakes, the port through which the venting normally takes place can be closed by a hand-operated valve 42. Venting can then only take place through a governor controlled valve when a predetermined low speed is exceeded. This valve is also adapted to vent the train pipe when a definite high speed is exceeded, irrespective of other conditions. The valve de vice comprises an elongated casing 10 within the upper end of which works a piston 11 which is held at its uppermost position when the train is at rest, but is moved downwards more or less according to the running speed by a governor 13 driven, for example, from a wheel axle. The pipe 41 communicates through the casing with a channel 15 in the piston, and a vent port 14 which is blanked by the lower portion of the piston in its raised position is put in communication with pipe 41 through channel 15 when tne piston is lowered a predetermined extent. In the lower part of the casing is a second independent piston 17, normally raised. In its raised position this piston allows communication between pipes 46, 47 bridging a normally-closed cock 48 in the train pipe 45. Supply to the train pipe to the left of this cock is thus established. When the piston 17 is lowered, this supply is cut off. At the same time a normally-closed valve 27 carried by a rod 26 below piston 17 is unseated, and vents the train pipe through openings in a cap 30. Piston 17 is lowered when a predetermined high speed is reached, by an adjustable screwed stud 32 in piston 11. Specification 215,338 is referred to.

[Class 81 (ii).] In an appliance for administering inhalations, such as anµsthetic gases or vapours or oxygen, the facepiece is so mounted as to be displaceable from normal position when required for use and to return to normal position when released. As shown, the facepiece A is mounted on a preferably upwardly tapering flexible tube B comprising a helically wound metallic strip of decreasing thickness towards its upper end. The tube B is lined with gastight material such as rubber and is provided at its upper end with an iris diaphragm B<4> operated by a knurled ring B<6> to control the gas flow. A lever B<3> controls the usual gas and air-mixing valve. The tube B is mounted on a metal gas reservoir C the contents of which are admitted to the tube only when the latter is displaced from the normal position by the lifting of a spring-held valve B<11> connected by wires D with the upper end of the tube. A recess J in the reservoir is adapted to receive an ethyl chloride bottle K the nozzle K<2> of which rests on, and on pressing the bottle downwardly, opens, a ball valve J<3>, a shoulder J<7> in the recess simultaneously depressing the bottleopening lever K<1>. The pressure of gas in the reservoir C is controlled by a valve H<I> connected by a rod H<2> to a diaphragm H<3> subject on the outer side to atmospheric pressure, excessive internal pressure causing the valve H<1> to close a gas-admission port H in a pipe F3. The reservoir C is carried on a wheeled stand which also supports two cylinders of nitrous oxide and one cylinder of oxygen, each cylinder being furnished with a reducing valve, a handoperated valve, a gauge, and a pipe connection to the gas-pipe F<3>. The spindles of the nitrousoxide gauges may each be connected to the valve of the other cylinder such that one of the cylinders is only opened when the other cylinder is exhausted. The gas control device H<1> .. H4 may be replaced by a weighted piston or the reservoir C may be replaced by leather bellows having a weighted top, provision being made to close the gas valve when the piston or the bellows top is in its uppermost position. The flexible tube B may be carried by or constitute a swivel or overhanging arm or may depend from the ceiling.
