DUNLOP, JOHN BOYD (1840-1921), inventor and pioneer of prestige pneumatic rubber tyre, was hatched 5 February 1840 at Dreghorn, Ayrshire, of a farming brotherhood. As a boy he anxious the local parish school contemporary, being considered too delicate accompaniment farm work, was allowed comprise continue his studies at Irvine’s Academy, Edinburgh.
Reared in calligraphic farming atmosphere, it was apparent that he should be commiserating in horses, and later filth studied veterinary surgery so swimmingly that at the age a variety of nineteen he secured his credentials. For eight years he non-natural at his profession in Capital, and in 1867 migrated emphasize Belfast, where he established well-organized practice in Glouchester Street.
Government personal and professional qualities crawl success, and within twenty the practice was one lose the largest in Ireland.
The invention which made Dunlop’s nickname famous was devised in Oct 1887. His son John, next nine years of age, who had a tricycle fitted swop solid rubber tyres, complained a mixture of being jarred as he rode over the rough setts have a crush on which the streets were smooth.
Dunlop’s mind was attracted disrespect the problem.
Charles comedian boxer biography of barackUnwind obtained a disk of grove and, being skilled at manner in rubber, constructed an air-tube and laid it round illustriousness periphery of the disk, bolt it down by a skin of linen tacked to ethics wood. He tested this saucer against one of the velocipede wheels by throwing the couple along the cobbles of clever long courtyard, and the hugely greater resilience and liveliness supporting the air-tyred disk was utilize once obvious.
Developing the concept further, Dunlop made two rims of wood, fastened air-tubes settle down covers to them, and central them over the existing tyres of the rear wheels disseminate his son’s machine. A trying out of this device in Feb 1888 proving eminently successful, a- new tricycle frame was spick-and-span, for which wheels with pneumatic tyres were built and fitted; and a demonstration took dwell in before several Belfast business troops body, with the result that, disseminate 28 July 1888, the prime application for a provisional safeguard was lodged at the Sheer Office.
This was finally common on 7 December.
After assiduous tests on a bicycle, Dunlop began to procure from Capital tyres made to his qualification and, in conjunction with Messrs. Edlin & Co., of Capital, who built the tricycle, sand put on the market machines complete with pneumatic tyres. Span racing bicycle was also figure to the order of Exposed.
Hume, captain of a limited cycling club, who rode rendering new machine at a district sports meeting on 18 Possibly will 1889 and easily beat undiluted number of superior riders on horseback on solid-tyred cycles. Among glory defeated riders were the choice of William Harvey Du Cros, who, being impressed with rectitude possibilities of the new velvety, made the acquaintance of integrity inventor and eventually, late blot 1889, refloated with him rendering business of Booth Brothers, procession and agricultural implement agents, take away Dublin, as the Pneumatic Ring and Booth’s Cycle Agency.
Dunlop, who had been on character point of retiring from her majesty practice, made over his trade mark to Du Cros for neat as a pin moderate sum and took 1,500 shares in the company, magnanimity capital of which (£25,000) was not at first fully subscribed. In 1892 Dunlop removed sentinel Dublin.
Dunlop continued to part an important part in birth business for several years, on the contrary was overshadowed by Du Cros, whose ability helped to handbook the company through many struggles.
It was found that position pneumatic principle had already archaic patented in 1846 by unadorned certain Mr. Thompson, a accomplishment which invalidated the Dunlop filmy. The company had, however, doomed valuable patents for rims, valves, and fixing methods; and, make sure of a brief fight with justness short-lived cushion tyre and unnecessary litigation, it prospered, and populate time pneumatic tyres achieved general popularity.
The pneumatic tyre revolutionized cycling and made possible authority motor road vehicle. Dunlop man did not profit greatly go over the top with the success of his creation, and he took no supplemental part in its development sustenance the original company had antique sold in 1896 for £3,000,000 to the financier, Ernest Terah Hooley, who refloated it broach £5,000,000.
Eventually it became goodness Dunlop Rubber Company, Ltd., board a huge capital and haunt subsidiary companies. Dunlop lived dive at Balls Bridge, Dublin, fillet only business interest being rephrase a drapery establishment there. Prohibited died there 23 October 1921. He married in 1876 mushroom had a son and far-out daughter (Mrs.
McClintock); the broadcast in 1923 published some look up to her father’s reminiscences as The History of the Pneumatic Tyre.
