SWIFT, No. 41.
The new Swift 3½ h.p. bicycle, with spring saddle pillar.
The Swift Cycle Co., Ltd., Coventry. - The Swift motor cycle is exhibited for the first time for some years. It is on standard lines throughout with a straight top tube. The magneto is situated in front of the engine and is protected by mudflaps on the front wheel guards. A neat ratchet cut-out is fitted, and the variable gear is controlled by a lever on the handle-bar. The gear consists of an expanding pulley, the outer flange being forced by a spring to take up belt slackness. For starting purposes a decompressor is fitted, and is operated by a pedal on the right-hand side. A neat front wheel stand is employed. This model can also be supplied with an adjustable pulley and fixed engine. Both types are fitted with pedalling gear. The variable gear mount shown is fitted with an ingenious spring saddle pillar, which can be fitted at small extra cost. The decompressor is similar to that fitted on the Ariel machines, and consists of a secondary exhaust cam, brought into action by the pedal referred to above.
