There was also a lightweight model fitted with a 2.25hp inclined engine. Very successful after World War I supplying engines for many manufacturers, but, as more companies developed their own engines, JAP relied heavily on industrial engine sales in the 1930s. Directors are John Alfred Prestwich, Chairman and MD; John Edgar Vincent Jobson; Edward Stuart Prestwich; Douglas Percival Prestwich; Gerald Winfrid Stanfield Bagshawe and Percy Gyllenship Langford.
1905 Motorcycles continued with a 2.5hp and a 3.5hp, as well as a three-wheeler. Produced a 3.5hp single, a 6hp V-twin and a forecar having an 8hp three-cylinder in-line engine. 1908 The company stopped motorcycle manufacture in order to concentrate on engines. In the late 1920s / early 1930s they produced various heavier engines under licence including those for the UK market for Light Aircraft Ltd's Aeronca light aircraft.
By November 1897 Prestwich was selling the redesigned Moto-Photograph apparatus, which shared the same mechanism as the Duplex machine but was able to utilize the more standard 35mm film.
The design was awarded a silver medal at the Glasgow International Photographic Exhibition, in part thanks to his older brother Edward (E.
In 1896 Prestwich teamed up with William Friese Greene to patent and construct a projector with twin vertical lenses, one of many early film devices designed to eliminate the “flicker” between frames by ensuring that there was always an image on the screen.
Unfortunately it required a specially designed film and failed to achieve much commercial interest.
It went into some limited production in 1902, and by 1903 one of the company’s first advertisements appeared in the April issue of The Motor.
The Triumph Cycle Company had already begun production of a dedicated motorcycle, the ‘No 1’ (1902) designed by Mauritz Shulte using a strengthened bicycle frame with a 2.25bhp single cylinder Belgian Minerva engine.
The last full JAP motorcycle for many years rolled off the floor in 1908, but engine development and improvement continued unabated.These were the real beginnings of the legendary British companies such as Triumph, Norton, BSA and Royal Enfield, as well as their competition across both Europe and North America.Yet while most of them had a strong mechanical background in frame and fork designs, they still lacked the facilities or engineering to design their own engines.P.) who handled most of the firm’s limited motion picture production.In 1898 John married Elinor Bramley; he bought two properties on Lansdowne Road, Tottenham, to provide the production facilities he needed for the rapidly expanding Prestwich Manufacturing Company.
