WHEEL RIM. — Bradshaw. — No 20,906, dated 20th September, 1906.—On the wheel (A) is a rim (C) which has a stationary flange (E) on one side, and a movable flange (H) on the other side. The flange (H) is screwed on to the rim (C), and is so arranged that, in one position, the flange will be concentric with the wheel axis, but, when rotated half a turn,
it becomes eccentric with the wheel, and thus enables the tire to be removed.
TRANSMISSION GEAR.—Nevers.— No. 14,709, dated 27th June, 1906.—The motor (I) is arranged in the front of the vehicle, with the and coupling (i). from the motor change-speed gear (g) Motion is transmitted to the road wheels through the shaft (j), the differential (h), shafts (a), bevel wheels (b), pinions (c), and bevel wheels (d), the latter being fixed on the hubs of the wheels. The double pinions (c) are mounted on an extension (e) of the vertical pivot of the axle journals to enable the wheels to be turned in any direction for steering the car without interfering with the driving, BREAKAGE TESTER.—Smith.--No. 17,309, dated 1st August, 1906. — The specimen to be tested has one end clamped in a frame (F) and the other end secured to a rod (B) free to slide in the frame. This rod may be loaded by a spring (H), so that any desired degree of stress is put upon the specimen. The rod has a bearing (N) fast upon it, wherein is mounted a rotary shaft carrying two discs (K). On each disc is an eccentrically disposed weight and suitable means are employed for rotating the discs so that an alternating stress is put upoa. the specimen by the centrifugal action of the weights.
LIT13RICATORS.—Knoller.—No. 6,103, dated 13th March, 1907.—This invention relates to lubricators of the type in which a feeding piston and a distributing piston work in separate cylinders. The feeding piston (a) and distributing piston (6) work separately in the cylinders le, by!, The shaft (c), which is revolved by gearing (dl, carries the eccentric (c1) revolving in the eccentric strap (f). The latter is formed as a cross-head, and carries, on each face, a stud (g) which slides in a slot (h) in the pump casing (p). The ends (i, k) of the pistons (a, b) are engaged with the crosshead of the eccentric strap, and the pistons receive a reciprocating movement as the eccentric shaft revolves.
SOLID TIRE.—Oldfield and another. No. 17,529, dated 3rd August, 1906.—This tire is recessed on its inner periphery so
that projections (K) are provided. These projections lie between corresponding projections on the feline of the wheel and the tire is secured by a detachable, side flange ; one flange (H) on the felloe is rigidly secured in place. The :ecesses (MI formed in the tire give increased resiliency, and the sides of the tire are also recessed as shown at N, whereby the resiiency is still further increased.
