A New Southey Carburetter. Improved Piston Construction. esting Four-wheel Drive. A Multi-jet Carburetter.
S. 0. FERRY, No. 12,772, dated 25th May, 1914.—This specification describes a feather-weight piston particularly suitable for use in automobile engines.
The piston-body is reduced in thickness so far as possible and two large openings are made on opposite sides of it. At the top of the piston two grooves are provided for the piston rings, and an internal shoulder is provided below these rings. The cross-member to receive the gudgeon-pin is of approximately rectangular cross-section, having the ends rounded to fit within the piston. This member is bedded against the internal shoulder in the piston so that the driving thrust is transmitted from the piston through the shoulder direct to the cross-piece and gudgeon-pin, and fastenings are provided to hold the parts in place.
A. FORD, No. 27,510, dated 29th November, 1913, Cognate Application No. 28,979/1913. In this carburetter a series of four jets in a row is supplied from the ordinary float-feed chamber. The air-supply enters the chamber in which the jets are arranged, and some of it passes up through choketubes around the jets, while the remainder passes up a passage at each side of the row and meets the mixture in the induction pipe.
Above the row of jets there is mounted a perforated plate with the perforations displaced from the jets so that a passage is provided only when the plate is lifted off its seat by the engine suction. The plate may be made of sufficient weight to act by itself or light springs may be provided above it After passing the plate the mixture enters a heated vaporizer of the ordinary type and then passes out through a hit-and-miss valve, mixing with, the unheated air.
In an alternative construction which is described in the specification a series of ball valves is used, one above each choke-tube. The balls may be graduated in weight, so as successively to effect the various jets. A. W. SOUTBLEY, No. 27,573, dated 1st December, 1913.— In this carburetter the fuel is sprayed from a jet by an ejeotor device supplied with high-pressure gas from one of the cylinders•on its compression stroke. The high-pressure gas enters by the connection on the left hand side at the bottom in the accompanying drawing, and the ejector extends upwards through the float-feed chamber; the fuel enters the jet by a side opening and is coarsely sprayed and carried up to a transverse passage through which the air enters. This air passes through the spray and some of the fuel evaporates to form the mixture, the excess liquid flowing back into the float-feed chamber. The throttle-valve is arranged to serve as a baffle to reduce the velocity of flow of the gases so that the tendency to draw away any liquid in suspension is reduced.
E. H. Semi...mu, No. 7364, dated 23rd March, 1914.—This specification describes in detail a construction of axle and driving-gear for a vehicle on which the steering-wheels are also used as driving wheels. . The axle-housing is provided at each end with a stout semi-circular yoke the two arms lying in a vertical plane. A vertical pinion-shaft is mounted in theca two arms and it carries at each end a bevel pinion which is supported in ball-bearings; these bearings lie in flanged recesses en the yoke arms. This spindle also serves as the knuckle pivot, the stub axle being formed integral with it and the steering bracket connected to its lower end in the usual manner. The drive is transmitted from the shaft through a large bevel gear-wheel to these two pinions and from them to a second large bevel wheel bolted direct on the road-wheel. Bali-bearings are interposed between the bevel pinions and the knuckle pivot so as to sustain the weight of the machine without materially increasing the friction when steering.
