Stand 63 THIS exhibit is characterized by three entirely new models, of which the rigid six-wheeler, known as the fitiRX, is the most outstanding. The four-wheeled bogie has a unique suspension system, termed as being of the gravity, spring type. The mounting of the forward axle is on semi-elliptic springs, the rear axle of the bogie being coupled to the after-end of these springs, by a beam shackle mounted to the spring and mounted on the rear axle by a ball-joint. Passing through this beam is an eccentric cross-shaft on the inside end of which is provided an anchoring point for a chain connected to a. long helical spring. This provides an effective damping device, for, as the beam moves up and down with spring movement, the eccentric crossshaft moves in sympathy, receiving a checking action through the damper spring.
Ea4 ing a normal four-speed box. A particularly strong form of frame construction is secured by the employment of duplicated side members, one of which fits within the other.
Of the two other models shown, one, the 45, is a 2i-tormer, and the other, known as the 50, a 2-3-tonner. The power unit in each case is six-cylindered with a rated output of 27.34 h.p., and a maximum output Of 66 b.h.p. at 3,000 r.p.m. The drive from the four-speed gearbox is by a Hardy Spicer open propeller shaft with a central trnnnicin bearing consisting of a double-thrust roller assembly mounted in rubber.
By mounting the cab well forward it has been possible Ur provide 12 ft. of body space on the 2-3-tonner. The appointment and comfort provided in the driver's cab in these models is noteworthy_—Diamond-T Motors, 414, London. Road. Isleworth, Middlesex.
