7 h.p. Model (twin-cylinder, V type): 87x95 mm.; overhead inlet valves, m.o.; B. and B, carburetter; chain; two-speed gear.
Quadrant Co., Lawley Street, Birmingham.
This fine sidecar machine is the attraction on the Quadrant stand. The engine is well up to its work and is an entirely new design with the magneto carried at the rear. The frame is sturdily built, and the chains have neatly designed guards.
The gear is mounted in the counter-shaft, and is of the selective clutch type, whilst handle starting is provided. Underneath the left footboard, a long silencer of big capacity is located. A new form of spring fork makes its first appearance.
Single-cylinder models, on much the same lines as the twin, but with belt drive, are also exhibited. One is pleased to note that the Quadrant retains the excellent characteristic of a smooth crank case, rendering the cleaning operation much more simple, and, generally, the new Quadrants appear very workmanlike designs. They embody up-to-date practice throughout.
The Quadrant Co., of Lawley Street, Birmingham, are manufacturing a large twin - cylinder engine for passenger work. It has the cylinders set at 50° and a bore and stroke of 87x95 mm. respectively. The inlet valves are placed over the exhaust and are particularly simple to remove. The design of the engine is characterised by its simplicity and strength. The operation of the valve gear will be observed from the illustration reproduced. A straight induction pipe is used with the carburetter, placed exactly central.
This new engine is to be fitted to a chain-driven bicycle with change speed gear, and should then make a fine machine for passenger work.
The original Quadrant Co. was one of the first firms in this country to take up the manufacture of motor cycles, and it is pleasing to note that, despite vicissitudes, the name Quadrant is still to the fore.
