1910 Olympia Show Report
CLYNO, No. 262x.
5-6 h.p. Clyno, with encased mechanically-operated valves and new pattern exhaust lifter.
Clyno Eng. Co., Pelham Street, Wolverhampton.
The principal exhibit on this stand is a new twin-cylinder model which is now made either as a bellt-driven single-geared machine or chain-driven with a two-speed gear. The Clyno engine is a neat piece of work, having two special features in the shape of detachable aluminium valve covers and a very neat exhaust valve-lifting mechanism which is enclosed in the timing gear case and is notable for its easy working. The carburetter is placed between the V-set cylinders and two separate silencers are used. The magneto is well behind the engine, where it is driven by a chain enclosed in a metal case. Druid spring forks are fitted, and the petrol and oil tanks are of ample capacity.
A variable engine pulley of Clyno design is fitted. The rear foot brake is of an unusual type, as it works on the outer side of the belt rim, thus rendering it possible to take the back wheel completely out simply by undoing the nuts on the hub spindle. On all the Clyno machines the company's special stand is fitted. It consists of two vertical sliding rods on each side of the rear hub, to operate which the machine is leaned over, one rod is then pushed down and locked into one of three notches by giving it a half turn. The machine is then leaned over, using this rod as a fulcrum and the second rod pushed down and locked into position. The use of three notches enables the machine to be held vertical on sloping or irregular ground.
In addition to this model one is shown fitted with the Clyno two-speed gear which is carried on the chain stays in the rear of the engine, and can he had giving any desired ratios of gear. In conjunction with this gear a hand starting arrangement is used, so that the machine can be started with the back wheel stationary on the ground.
A single-cylinder model with an engine having a bore and stroke of 76 x 85 is also exhibited, the rest of the machine having a similar specification to the single-geared model described above.

Clyno Engineering Co.
Stand No. 262X.
This firm show three patterns of motor-cycles, one type being fitted with a side-car. The two heavier
machines are both of 5-6 H.P., but one is belt driven, whilst the other is provided with two chains,
and a two-speed gear is arranged. These two machines are fitted with partial
covers to the valves—a step in the right direction. A single-cylinder 2¼ H.P. machine, of the belt-driven class, is also exhibited, and is a
very handsome machine.
