LIQUID-FUEL BURNER.—Gillett. No. 20,866, dated 3rd October, 1908.— This invention relates to liquid-fuel burners, and mote particularly to those applicable for use on motor vehicles and steam launches. The burner comprises a number of narrow Imes arranged side by side with small spaces between them so as to form a grid or grate. The liquid-fuel supply pipe is zigzagged through holes provided in those bars and looped, a number of times, on the top thereof. It is then coiled and finally connected to the fuel nozzle which extends into a bell-mouthed air tube. This tube extends into the mixture chamber, and under the aforementioned bars. A lamp is situated beneath the coiled portion of the fuel-supply pipe, fm. the purpose of vaporizing the liquid fuel on starting the burner, It will be seen that the bars which form the grid or grate are cooled by the fuel being passed through them, and the heat of the bars is utilized for vaporizing the fuel.
DRIVING GEAR. — Tracy and Others—No. 28,018, dated 23rd`Decemher, 1908.—This invention relates to mechanism for enabling one driving wheel to overrun the axle, when the vehicle is rounding a curve, thereby dispensing with the necessity for the usual differential gear, as described in specification No. 13,61107. The object of the present invention is to adapt the mechanism of this type to an undivided axle, by the use of which one wheel only can run freely, and braking through the engine can be effected. The undivided axle is provided at each end with a screw-threaded collar on which is mounted the male member of a doubleconed clutch, the other member being bolted to the huh of the wheel. The male clutch member has an extension of reduced diameter to receive a friction ring, which provides the necessary friction to cause the male clutch member to travel upon its thread when relative movement tends to occur between the wheel and the axle. The two clutches are connected together by a rod that extends through the axle, in such manner
that only one of them can he in its neutral position at one time. It will be seen, therefore, that both the rear wheels are not permitted to overrun the axle at one time.
VALES.—Hiscocks and Another.— No. 24,098, dated 10th November, 1908. —This invention relates to an improved arrangement of inlet and exhaust valves for internal-combustion engines. The valves are of the sleeve type, and are arranged to reciprocate in a cylindrical valve-chest, that communicates with the cylinder by means of a suitable port. The sleeve valves telescope one within the other, and each is provided with a port that is adapted, at the proper time, to register with the port in the cylinder wall. The upper end of the valve chest communicates with the exhaust pipe, and the lower end with the induction pipe.
ROAD TRACTOR.—Fowler and Another.—No. 5,698/09 (Patent of Addition to Specification No. 8,640, dated 18th April, 1908).-This invention relates to driving gear for road tractors of the kind described in Specifications Nos. 14,242 of 1892 and 8,640 of 1908, in which provision is made for the rear road wheels to move relatively to their gears without disturbing the latter. According to this invention the rear axle is mounted eccentrically and free to move vertically within the boss of a gearwheel that drives it through the medium of an intermediate wheel. The intermediate wheel is connected to the driving wheel by crank pins or links.
