STARTING HANDLE. -Draper. -No. 9,506. dated 19th April, 1910.—This invention describes a startine handle xehich is designed to protect the operator from injuries due to uack kicks. The crank handle is loosely hung on a huli which is secured to the engine shait by a setscrew. The handle can be locked to the hub by a locking pin, \shit+ is slidably mounted in the back of the crank and engages with fiat portions on the hub. The locking pin is held in engagement by means of an" inertia member. This is provided with a shoulder that engages the locking member and holds it up to the hub. The " inertia member is pivoted on the crank, so that, if any back kick be obtained in starting the engine, the consequent jar and the inertia of the pivoted member combine to releesee the locking member on the shoulder, and thereby to render the I endle free upon the engine shift.
MOTOR LORRIES. — Burrell and Wilson.--No. 20,738, dated 10th September, 1909.—This specification describes a lorry, which is driven by an engine of the traction-engine type that is arranged in front of the vehicle. The differential gear is arranged upon a countershaft directly driven by the engine, and the rear wheels are independently driven by two chains gearing with chain wheels fixed to the countershaft. At, the rear, the chains gear with ehein wheels that are loose on
a transverse shaft, and fixed to these chain wheels, are gear wheels which engage with internal gears on the road wheels. The transverse shaft carrying the rear driving pinions is carried on a pair of frames which are adjustable in length to take up any slack in the driving chains.
PETROL TANKS. — The AngloAmerican Oil Co. and Another.—No. 10,819, dated May 2nd, 1910.—This specification describes a petrol tank whichhas the spout and stopper formed integrally with one another. The spout is arranged to rotate on a disc fixed in the top nf the can, and it has its inner end closed by a disc which has two holes in it. Two similar holes are formed in the disc in the can, these have their edges dished to diminish friction. When the spout is turned outwards for use, the corresponding holes in the two discs are coincident and the liquid is delivered. When the spout is turned through a right angle, the holes no longer coincide awl the vessel is closed. The spout then lies wholly within the snrfac.e of the call, ith no projecting parts liable to
damage. An air hole is provided at the inner end of the spout communicating with a small chamber there, which is open to the interior of the can through one of the holes This permits air to pass in, as the liquid passes out, and ensures a smooth delivery.
CARBURETTER. — Brown. — No. 27,636, dated 27th November, 1909.— This specification describes a variable jet for a carburetter. The jet consists' of a tube closed at. its upper end, with a small orifice in the side near the top. The petrol enters by the horizontal pas sage shown and passes nit by this orifice. Surrounding the tube is a sleeve, the upper edge of Which is formed in a helix. The tube is of such length that, on rotating it, it will completely cover or completely open the jet. In the arrangement shown, the tube is arranged to rotate inside the sleeve. A stuffing box is provided at, the lower end to prevent leakage, and a spring keeps the shoulder at the upper end tight. The operating lever may be connected with the throttle valve, and, if this be so, the mechanism may be modified to provide easy variation of the mixture. This is_ shown in the second figure, where a similar arrangement changes the mean position of tilt hole in respect to the sleeve.
TIRE CLAMP.—IJellner.—No. 10,193, slated April 26th, 1910.—When two tire ce% ere are put on one wheel from motives of economy, it is found that the outer cover slides on the lower one and injures it when the vehicle is started or stopped. This invention relates to a clamping device to prevent this motion. It consists of two claw-like arms hinged to a link which is tapped and provided with a tightening screw. This screw bears on a plate on the inside of the rim. The dew arms, when tightened, hold the outer cover down on to the inner cover, and an additional bridge piece is provided which bears against the arms and prevents any lateral spread of the cover.
