No. 13518.—29th March, 1901.—HENRY ISMAY MORALEE ROSS, of Dunedin, New Zealand, Engraver. Improved ventilation for cars or buildings.

Claims.—(1.) In car-ventilating apparatus, comprising an air-purifying chamber having an external intake, mechanism for discharging the air from the said chamber into the car, an independent intake extending in the same direction as the said chamber-intake, and an air-motor in said independent intake coupled to and operating the discharge-mechanism. (2.) A ventilating-apparatus for cars comprising a wind-driven or air motor, a ventilating-fan actuated solely by said motor, an air-chamber partially filled with water, an air-inlet open in the direction of the car, the other end of the said inlet being below the surface of the water, a pipe leading from said chamber to said fan, and a pipe leading from the fan to the interior of the car, whereby the air-inflow into the said chamber will be positively discharged proportionately to its ingress, regardless of the wind-velocity and car-speed. (3.) A ventilating-apparatus for cars consisting of a wind-driven air-motor, a ventilating-fan actuated solely by said motor, an air-chamber partly filled with water, an air-inlet open in the direction of movement of the car, the other end of the said inlet being below the surface of the water, a pipe leading from said chamber to said fan, the inlet end being above the surface of the water, and a pipe leading from the fan to the interior of the car, whereby the inflow into the said chamber of air will be discharged proportionately to its ingress, regardless of wind-velocity or car-speed. (4.) In a ventilating system, an elevated tank partly filled with water, and an external-air-collecting funnel disposed in front of the tank and provided with a spout which terminates in said tank below the normal water-line, combined with a wind-driven motor (or power-driven motor in the case of buildings), a suction and forcing fan and a distributing-pipe leading from the suction and forcing fan, substantially as described and shown. (5.) In a ventilating system, the double fan-casing having two compartments, one of which has a normally open outlet at one side thereof, and a collecting-hood on its other side open to the air, a single fan-shaft for both fans, said fans having blades curved in opposite directions, combined with an air-purifying tank with its air-intake opening in the same direction as the motor-fan intake, a pipe connecting said tank with the suction or forcing fan, and a distributing-pipe leading from the suction or forcing fan, all substantially as described, and as illustrated in the drawing.

No. 13523.—2nd April, 1901.—THOMAS BOYD, of Gloucester Street West, Christchurch, New Zealand, Cycle-manufacturer. Improvements in saddles for cycles.

Claims.—(1.) In a saddle for cycles, the combination with the bottom frame and rear spiral springs of a continuous steel wire A, curved to form two springs in front, and looped at bottom to connect to bottom frame (or a separate wire for each said spring, the lower ends fitting in a bracket connected to bottom frame), each rear end of said wire having attached thereto a piece of (preferably stamped) metal C forming the seat, the rear end of each said piece of metal being connected to the upper end of the corresponding spiral spring at back, the lower end of which is attached to the cross-piece connecting the rear ends of bottom frame, thus enabling the two parts forming the seat to be independent of each other, and leaving a space between them to avoid all pressure upon the perineum, while each said part can be so covered as to give relief to the seat-bones of the rider, substantially as described, and illustrated in the drawings. (2.) In a saddle for cycles, the combination with the bottom frame and rear spiral springs of a continuous steel wire A¹, curved to form two springs in front, and looped at bottom to connect to bottom frame (or a separate wire for each said spring, the lower ends fitting in a bracket connected to bottom frame), each upper end of said wire being curved to form the seat and connected to the upper end of the corresponding spring at back, the lower end of which is attached to the cross-piece connecting the rear ends of bottom frame, thus enabling the two parts forming the seat to be independent of each other and leaving a space between them to avoid all pressure upon the perineum, while each said part can be so covered as to give relief to the seat-bones of the rider, substantially as described, and illustrated in the drawings.

No. 13525.—4th April, 1901.—CHARLES GROSVENOR, Public Accountant, FRANK HENDERSON, Engineer, and ROBERT LOGAN the younger, all of Auckland, New Zealand. An improved appliance for producing gas from gasoline and other hydrocarbons by the propulsion of atmospheric air therethrough.

Claims.—(1.) In the appliance above described, the observation-chamber for connecting the drip of gasoline or other fluid from the piping leading from the reservoir into the generator, for the purpose set forth, substantially as described and illustrated. (2.) In the appliance above described, the exit-channel or pipe through which the gas rises, and is reinforced by the drip of gasoline or other fluid falling through the observation-chamber from the piping leading from the reservoir, for the purpose set forth, substantially as described and illustrated. (3.) In the appliance above described, the placing of the check-valve in the air-inlet pipe for the purpose set forth, substantially as described and illustrated. (4.) In the appliance above described, the chamber fixed below the air-inlet pipe beneath the generator for the purpose set forth, substantially as described and illustrated. (5.) In the appliance above described, in combination, the cylindrical tank or generator connected to the reservoir by piping and fixed to said piping-cock and chamber for regulating and conducting drip of gasoline or other fluid, hole for charging tank or generator with fluid, outlet-hole for gas, drain-cock for carrying away waste products, air-inlet pipe fixed to outside of generator, passing into generator, and having beneath it drainage-chamber for moisture from air, projection fitted to upper part of generator in direct line with part where air-inlet pipe enters under part of generator, float with upwardly shaped funnel projection, closed at its top with up-right rod fitted to outside of said projection, and with a coiled or radiating air-way forming portion of said float, said rod to rise into projection on top of generator, said upwardly shaped funnel projection to enclose inner end of air-inlet pipe, discs, stays, and threaded wicks, and gas-exit channels, all for the purpose set forth, substantially as described and illustrated.
