No. 13740.—22nd June, 1901.—WILLIAM NICHOLLS, of 8, Barnard’s Inn, Holborn, London, England, Gentleman. Improvements in apparatus for supplying aerated liquids from bulk on draught.

Claims.—(1.) In apparatus for supplying aerated liquids from bulk on draught, the combination with a reservoir for containing aerated liquid under pressure of a rotatable controlling-valve forced on to its seat by the pressure of the aerated liquid, a handle disconnected axially from the valve and operating the same between stops, a measuring-vessel into which the liquid is forced from the containing-reservoir, and means for automatically closing the outlet of the measuring-vessel when it is in communication with the containing-vessel, and opening it for the egress of the liquid when the vessel is closed to the containing-vessel and open to the atmosphere, substantially as described. (2.) In apparatus for supplying aerated liquids from bulk on draught, the combination of a rotatable controlling-valve forced on to its seating by the pressure of the aerated liquid, a spindle having projecting horns or tongues engaging in notches in the valve, a spring forcing the valve and the spindle on their seatings in the valve-chamber, a handle fixed on the valve-spindle and working between stops, substantially as described. (3.) In apparatus for supplying aerated liquids from bulk on draught, the combination of a rotatable controlling-valve forced on to its seating by the pressure of the aerated liquid, a spindle having projecting horns or tongues engaging in notches in the valve, a spring forcing the valve and the spindle on their seatings in the valve-chamber, a sleeve fitting in the valve-body and prevented from rotating therein, a cap nut for keeping the sleeve and spindle in position axially, a handle fixed on the valve-spindle, and stops on the sleeve and handle, substantially as described. (4.) Apparatus for supplying aerated liquids from bulk on draught, the whole arranged, constructed, and operating substantially as described, and illustrated in the drawings.

No. 13741.—22nd June, 1901.—GEORGE WESTINGHOUSE, of Westinghouse Building, Pittsburg, Pennsylvania, United States of America, Manufacturer. Improvements in car-couplings.

Claims.—(1.) An automatic car-coupling in which the coupler head is provided with a fixed vertical coupling-member adapted to be engaged with and disengaged from a corresponding member on a counterpart head by a lateral movement of the entire coupler-head, a lock being provided for retaining the heads in substantially rigid engagement, and with or without electric terminals in the heads by means of which an electric circuit or circuits is or are made by the operation of coupling. (2.) An automatic car-coupling in which the coupler-heads are maintained in substantially rigid engagement when coupled, and are each provided with one or more fluid-conduits having properly packed ends and with a cock for opening and closing said conduits when necessary, said cock being provided with operating-means, which also operate the lock for maintaining the coupler-heads in engagement. (3.) In an automatic car-coupling of the kind described, the provision of lost motion in the lock-operating mechanism for the purpose specified. (4.) Means for operating the lock and cock of an automatic coupling of the kind described in which the operating-handle is capable of assuming three positions, in the first of which the cock is shut and the lock withdrawn from engagement with the counterpart coupler-head, in the second of which the cock is shut and the lock is placed in its operative position, and in the third of which the cock is opened, the lock being in its operative position. (5.) In a car-coupling wherein the coupler-head is connected to the draw-bar or coupler-shank by a ball-and-socket joint, the provision of means whereby the movement of the coupler-head on such joint is opposed by a frictional resistance, substantially as described. (6.) Automatic car-couplings constructed and operating substantially as described with reference to the drawings.

No. 13742.—22nd June, 1901.—GEORGE WESTINGHOUSE, of Westinghouse Building, Pittsburg, Pennsylvania, United States of America, Manufacturer. Improvements relating to the production and utilisation of gas.

Claims.—(1.) Apparatus for the production and utilisation of gas, comprising a gas-producer and a gas-engine or like device so connected that the products of combustion from the gas-engine are caused to pass through passages in the wall of the producer in close proximity to air-passages in said wall, for the purpose specified. (2.) A producer in which the producing-chamber is surrounded by a series of tubes enclosed in an annular space, with or without deflecting-plates or walls dividing said tubes into groups, substantially as and for the purpose specified. (3.) A producer having a steam-raising or superheating coil or coils combined therewith in such a manner that after a portion of the sensible heat of the products of combustion has been employed in heating the air and steam supplied to the producing-chamber a further portion of such heat at a lower temperature is utilised in heating the steam-raising or superheating coil, substantially as described. (4.) A producer in which a supply of water regulated according to the amount of gas produced is provided in the wall of the producer, which is heated by the produced gas, the water-vapour thus formed being fed into the producing-chamber with the air-supply. (5.) Gas-producers constructed substantially as described with reference to Fig. 2, or to Fig. 9, or to Fig. 11 of the drawings, and with or without an incinerator, for the purpose specified.
