1910 Stanley Show Report
Brown Bros., Ltd.
Gt. Eastern Street, London. Stands No. 173-177.
The Brown motor-bicycle for 1911 has an engine of slightly larger bore and stroke than its predecessor of 1910, the dimensions being now 86 mm. by 86 mm., instead of 85 mm. square. A very excellent feature is the provision of adjustments to the valve tappets. The crankshaft rotates in ball bearings. The magneto is located in front of the crankcase, over the exhaust silencer, and the handlebar controlled carburetter is close up to the back of the cylinder. The top tube meets the bottom one at the head, the upper part of the socket being strengthened by a web. This brings the top down to 29ins. from the ground, about as low as it is possible to get it without bends.
The drive includes a rubber belt and variable pulley. The front
fork is of the double row type, and the upper end is linked to the top and bottom of the head, which
is suspended by other links from a collar bearing on a central main spiral spring, and surmounted by
a buffer spring. The lamp bracket is specially strong, and is incorporated with the handlebar lug.
The T.T. Brown is a good deal lighter than the full roadster, and is sent out without pedalling
gear, but either a rigid or a spring fork can be had, to meet the rider's wishes. Messrs. Brown
Bros. are open to appoint agents here they have no representatives and terms will be supplied on
Olympia Show, November 1910
1914 Late in the year the name appeared on a 225cc two-stroke model with a two-speed gearbox and chain-cum-belt transmission. They also listed a 4hp V-twin, with an overhead inlet valve, Bosch magneto, and various transmission options.
1915 They were now using either their own or Precision engines only. Production of Brown motorcycles ceased.
Post-war. A 225cc two-stroke single was listed.
1919 March. Adverts for Electric self-starters and Berdea carburettors. Issued catalogue on motorcycle accessories.
1920 A 976cc sv JAP V-twin was added.
1922 Those models carried on into that year.
1923 The two-stroke was replaced by a 292cc sv JAP model finished in art grey.
It is probable that most Vindec machines were bought-in designs from established manufacturers, finished and badged under the Vindec name. Some models of that period strongly resembled Rex-Acme machines.
1924 The big twin went and a 170cc two-stroke joined the JAP single for one season.
1925 The twin returned for that year only, along with the 292cc sv model.
1926 The 292cc sv model was enlarged to 300cc, and another lightweight two-stroke of 147cc was added for one season.
1927-1929 It was the 300cc sv JAP machine that carried them through to their final year of 1929.

THE BROWN MOTOR
MESSRS. BROWN BROS., LTD., have during the past few years enjoyed an excellent reputation as the vendors of first-class motor bicycles, so that it is not surprising that their 1907 models still maintain this high standard, with the addition of one or two important improvements and refinements.
Like all up-to-date firms, they are aware of the importance of turning out a thoroughly good two-speed gear. A single-cylinder (an illustration of which we herewith reproduce) is fitted with an epicyclic gear giving two speeds operated by the vertical lever, which is seen fixed to the side of the crank case. Pushing the lever forward applies a band brake around the gear drum, which puts the low gear in action.
With the lever vertical the engine is free, and drawn back the high gear is in action the whole of the gear being then locked and revolving as an extra flywheel. The counter-shaft bracket is provided with a swing adjustment, which thus allows the short chain to be tightened or loosened as occasion requires.
A starting handle is supplied in every case with this gear. No pedals are fitted, but comfortable footrests are supplied, which are attached to the down tube of the frame An interesting fitting on this machine is the petrol tap, which has two functions; firstly to admit petrol into the carburetter, and, secondly, to act as a drain tap.
Not only as regards two-speed gears are Messrs. Brown Bros, up-to-date, but being fully alive to the importance of reliability, they also fit magneto ignition to their 1907 motor bicycles. For the control of this a very neat and efficient switch has been provided, which is attached to the handle-bar...
