1924 Douglas 2¾hp Model TS Project
Frame no. 55883
Engine no. 65494
This '350' Douglas is an example of the TS model. The sidevalve engine is of 'fixed head' type with outside flywheel and magneto ignition, while the transmission comprises chain primary drive to a two-speed gearbox with belt final drive. The front fork is of the side-spring type, while retardation is achieved by a bicycle-type stirrup brake at the front and a v-block belt-rim brake at the rear. By 1924 chain drive had established its superiority and belt drive had disappeared from all except the cheapest lightweights. Douglas offered all-chain models but sought to explain their reasons for continuing with belt drive: 'Other manufacturers have discarded belt drive not because of the inefficiency of this type of transmission but because of the unsuitability of their particular type of engines. On a Douglas belt drive is most successful, owing to the smooth pull of the engine. The uneven torque of the "single" or the "chunk-chunk" of the V twin do not lend themselves to this type of drive. The shock-absorbing qualities of belt drive on a Douglas have only to be tried to be appreciated.' Apparently benefiting from some prior refurbishment, the machine is presented in a partially dismantled state and offered for restoration. Prospective purchasers should satisfy themselves with regard to the completeness or otherwise of this Lot, which is sold strictly as viewed. A box of related literature comes with it.
