CLAYTON AND SRupTLEWORTIL, LTD. P. W. ROBSON, and F. J. BRETDERTON, No. 16,459, dated 22nd November, 1915.— This invention re/ates to motor vehicles of the typo in which the front axle moves as a whole about a central pivot for steering purposes. The front axle ia formed, at the middle of its length with a spherical portion around which a socketpiece is fitted. On the top of this socket is fitted a laminated spring by which the boiler or front end of the vehicle is supported. A lug on the rear side of the socket provides a 'connection for the radius rods.
The invention is not restricted to a ball-and-socket universal joint, for any other construction may be used. With this joint the axle is free to turn in a horizontal plane for steering purposes or to turn in a vertical plane and accommodate irregularities in the road surface, but the thrusts of the radius rods and of the load do not cause any strain on the axle since they are applied to it through the universal joint.
D. NAPIER AND SON., LTD.; and. A. J. ROWLEDGE., No. 100,615, dated 29th February, 1916.—The accompanying 'drawings show a simple construction of spring-drive incorporated with a plate-clutch. The middle plate of the clutch is carried by two discs or annular plates in each-of which there are three trough-like recesses so arranged that when the plates are put together a chamber is formed by each pair of recesses. In each chamber there is a stiff coiled spring. The driving shaft carries a disc with. three radial arms, each of which bears on one end of a spring 'and, the other end of which spring bears against the annular plates.
When the outer plates of the clutch are brought together to grip the middle plate, a drive is transmitted to them through the springs and the, friction surfaces.
W. E. MARTIN, No. 13,779, dated 28th September, 1915.— This invention is an improvement on Patent No. 1581/15, in which the driving mechanism for agricultural machines consists of chains passing round carrying wheels which also serve as sprocket wheels. Aceordin to this invention, the sprocket-wheels are each provided. with a pair of flanges extending sideways from the teeth, and these flanges roll on the
side Links of the chain. The teeth are thereby relieved of the weight of the vehicle. The chain is made up of links which are alternately simple connecting links, and tread-carrying links which are formed with a flat plate to make contact with the ground.
11 BONFIELD, No. 8359, dated 5th June, 1915.—The drawings show a, construction of aide guard for steering wheels. A bearing ring is clamped to the spokes of the wheel on the outer side. On this bearing are two rings side by side. The inner one is held from rotation by a vertical rod engaging a bracket which can turn in line with the stub-axle pivot. The outer ring is eccentric, and carries a segmental mudguard. The inner ring carries a bow-shaped spring which bears 011 tho top of the outer eccentric ring and retains it in the posi-tion, shown in the side elevation.
The mudguard is free to move vertically on the eccentric ring through a limited range under the control of a spring at the bottom of the ring. Radial rollers on the outer side of the mudguard protect it from injury by contact with curbs. When the guard comes in contact with a curb, it is pressed in towards the wheel, and" carried round with the wheel until it is clear of the curb. As soon as it is free, its weight and the bow-shaped. spring return it to its normal position.
