Granted: 1902-10-23
Abstract: 23,673. Gascoyne, G. F. Nov. 21. Fog and audible signals; indicators and repeaters, signal ; contacts, pneumatic.-Relates to audible signalling-apparatus for use on railways in foggy or other unfavourable weather. The treadle A is mounted outside one of the rails C transversely to the track, and is pivoted at its outer end, its inner free end being formed with a projecting-rib B<2>, which is engaged by the flange of the train wheel D to effect the depression of the treadle. The rib B' is inclined at both ends. The treadle is fixed to a bellows adapted to sound the horn I<3>, or a piston and cylinder may be employed. In the arrangement shown, the bellows consists of a fixed base-plate E, E', having an outlet port E<2>, and a movable casing G, G', G<2> fixed to the treadle. The horn P is fixed to the port I<2> of the slide valve I, which may be connected to the ordinary signal mechanism, so that it is moved in one direction by the operation of the signal, and in the opposite direction by a spring. In one position of the valve, the port I<2> registers with the port E', and the air forced out of the bellows by the depression of the treadle sounds the horn. In the other position of the valve, a second port therein connects the bellows to the atmosphere, in which case the depression of the treadle does not sound the horn. When the treadle is released, it is returned by springs K. By employing a small air-inlet for the bellows, the upward movement of the treadle may be retarded, so that it is operated only by the leading wheel. The horn may be provided with two reeds, set reversely, so that one will sound when the treadle is depressed, and the other when it rises. The apparatus may be put out of action by fastening down the treadle, or by setting the bellows permanently in communication with the atmosphere. Two treadles may be employed, one outside each rail, and may be arranged to operate the same horn or independent horns or whistles.
