No. 16040.—17th June, 1902.—ARTHUR KITSON, of York Mansions, York Street, Westminster, England, Managing Director to the Kitson Lighting Company of Great Britain, Limited. Improvements in or pertaining to vapour-burning apparatus.

[NOTE.—This is an application under section 106 of the Act, the date given being the official date of the application in Great Britain.]

Claims.—(1.) In vapour-burning apparatus of the kind referred to, the combination, with a vaporizer, of a thermostatic device which is independent as to the adjustment of its valve of the vaporizer, and is so arranged as to be heated by the preheating device and subsequently either by the main burner or set of main burners or else by the auxiliary flame for normally heating the vaporizing tube, and which is adapted to allow oil to pass to the vaporizer only when the vaporizer has become sufficiently heated, and to prevent it from passing thereto when the vaporizer is too cool for proper vaporization. (2.) Vapour-burning apparatus according to the preceding claim, wherein the thermostatic device is arranged externally to the vaporizer. (3.) Vapour-burning apparatus according to either of the preceding claims, wherein a tube containing the thermostatic-valve rod is provided with inlet and outlet holes so that a current of comparatively cool air will pass therethrough when the tube is being heated. (4.) Vapour-burning apparatus according to claim 1 or claim 2, wherein the vaporizing-tube and the thermostatic device are both horizontal or approximately horizontal and arranged in the path of products of combustion ascending from the main burner or set of burners or from the auxiliary burner. (5.) Vapour-burning apparatus according to any preceding claim, wherein the thermostatic device is arranged or protected so as not to be heated as quickly to its final temperature as the vaporizer. (6.) Vapour-burning apparatus according to claim 1, constructed and arranged as described with reference to and shown respectively in Fig. 1, in Fig. 2, in Fig. 3, and in Fig. 4 of the drawings.

No. 16041.—3rd March, 1903.—JAMES REYNOLDS HAYNE, of 96, Princes Street, Dunedin, New Zealand, Chemist. Improvements in and relating to pneumatic hubs for the wheels of vehicles.

Claims.—(1.) In apparatus for the purpose indicated, in combination, the axle of a vehicle, a sleeve threaded and revolvable thereon, a collar fixed upon the axle and antifriction washers upon each side thereof, the sleeve being recessed to receive the collar and the washers, a cap threaded upon the axle and screwing upon the inner end of the sleeve, and a cap screwed upon the outer end of the sleeve, an axle-box fixed to the sleeve and having a projecting flange upon one end, a disc plate fixed upon the opposite end of the axle-box, a spoke-ring surrounding the axle-box and fitting between the flange and the disc plate, and a pneumatic tube within an annular recess between the axle-box and the spoke-ring, substantially as specified. (2.) In apparatus for the purpose indicated, in combination, the axle of a vehicle, a sleeve threaded and revolvable thereon, an axle-box fixed to the sleeve, a flange projecting from one end of the axle-box, and a disc plate corresponding with the flange secured upon the other end, a spoke-ring surrounding the axle-box and fitting between the flange and the disc plate, a pneumatic tube carried in an annular recess between the axle-box and the spoke-ring, and means for preventing the sleeve from sliding laterally from the axle, substantially as specified.
