advances in the development of the bicycle take place, one of the longer established high quality manufacturers being the Quadrant Cycle Company of Sheepcote Street, which later manufactures motorbikes (as do many cycle makers). Other notable firms are Reynolds (still manufacturing in the city), New Hudson, Rudge-Whitworth (also of Coventry), BSA, CWS, Dawes, Grundle, James Cycle Co, Ariel, Armstrong Cycles, Phillips Cycles, Excelsior (originally of Coventry), Sun Cycle & Fittings Co, Pashley Cycles (now manufactured in Stratford-upon-Avon) and Hercules Cycle and Motor Company. Through the 20th century, many of Birmingham's bicycle manufacturers evolve into automobile and motorcycle brands, creating one of the busiest and most productive engineering hubs in the world. Motor engineering brands such as Wolseley, Lanchester, Metro-Cammell, Austin, Morris, Vickers-Armstrongs, New Hudson, Revere, Beardmore, Sun, Ariel, Norton, Rex-Acme, Alldays & Onions, Velocette, Midland Red and BSA either originate or have substantial factories in Birmingham, manufacturing motorbikes, buses, tractors, cars, tanks and aeroplanes. Other diverse engineering companies develop to feed the supply chain of the motoring industry such as Webster and Horsfall (pioneering wire for aircraft and cars), Dunlop Rubber (supplying rubber and tyres), Lucas Industries (pioneering electric and lighting), Accles & Pollock (producing tubular sections for aircraft) and Pockley Electric (manufacturing car lights). 1900: Bournville Village Trust is founded by George Cadbury, this is to make many improvements and set high standards of living and leisure pastimes for factory workers across Britain. Cadbury's still makes chocolate in the city today and Bournville remains a sought after area to live in. 1900: John Wright invents a much-improved gas fire, which uses fretted columns of fireclay, rather than tufted asbestos, to radiate the heat. The Wright design of gas fire heating endures throughout the century, however, electric fires improve at a similar pace. 1902: The first caliper-type automobile disc brake is patented by Frederick William Lanchester in his Birmingham factory and used successfully on Lanchester cars. However, the limited choice of metals in this period means that he has to use copper as the braking medium acting on the disc. The poor state of the roads at this time — no more than dusty, rough tracks — means that the copper wears quickly, making the disc brake system non-viable. It is not until 1929, in the same city that manufacturers Girling and New Hudson further develop disc brakes, which are very successful on racing cars from the early 1950s to
