MAY 27, 1920 THE "WEB" NUT THE ordinary hexagon nut is such a common object that few people give a thought as to whether it is the last word on the subject. As a matter of fact, Messrs. Heritage, Holyoake and Co. have brought out an improved nut for which several advantages are claimed, especially for use in connection with aircraft. The general arrangement of the " Web " nut, as it is called, can be gathered from the sketch. It consists of a barrel with a flange at the lower end, and four webs arranged at right angles. The webs permit of the nut being screwed up or loosened by means of the special spanner, which is simply a short tube (with slots to fit the webs) attached to a handle, and the positive grip which is obtained makes the nut much easier to tighten or slacken than is the ordinary nut. It will be noticed four slots are cut between the webs. Apart from the fact that this lightens the nut to a certain The " Web " Nut put on the market by Messrs. Heritage, Holyoake and Co. . . extent, it also permits of the nut performing the double function of nut and lock-nut. When used on metal it is claimed that slight oxidisation is permitted opposite the slots, and this is sufficient to prevent the nut working loose. Again, when used on wood, the nut when screwed up allows the wood to swell into the slots just sufficiently to hold the nut and prevent it turning. As the nuts weigh less than those of ordinary design, and in ordinary cases render the use of a lock-nut unnecessary, it is possible to save a consider- able weight by their use. The nuts are made in a wide range of sizes, and Messrs. Herrtage, Holyoake and Co., of 127-128, Fleet Street, London, E.C. 4, will be pleased to quote for any quantity. They also supply the necessary spanners, which can be had either with the bar handle or with a " tommy " bar handle. • .. y * H H H H >>.. r'-^A Aeroplanes for Rumania held up •_•'•.• ::„. c:: ACCORDING to the Gazzetta del Popolo a train carryingFrench aeroplanes given by the French Government to Rumania has been held up at Brescia railway station by therailwaymen. the reason advanced for this action being a fear that the machines were to be used in an offensive againstthe Bolshevists. Up to the present no word has been received that the trucks containing the. aeroplanes havebeen allowed to leave Brescia. The Rome-Tokyo Flight LIEUT. FERRARIN arrived at Peking from Tsing-tao on May 17, and received a decoration conferred by the President of China, while the Chinese aviation department presented him with a silver incense burner. Lieut. Ferrarin on May 23 flew to Kowpantze, and later the same day landed at a town in the north-east of Korea. An Air Race in 'Frisco THK race flown on the opening day of the San Francisco Aeronautical Show for the Del Monte Trophy marked another triumph for British aircraft and aero engines, having been won easily by a " Bristol " two-seater tourer fitted with a 230-240 h.p. Siddeley Puma engine. The Bristol made an excellent start, and from the early stages of the 220-mile race displayed its marked superiority over its rivals. Flying without a hitch it completed the course in 102 minutes, an average speed of 129 miles per hour. The machine had recently been acquired by Mr. Menzel of California through the New York branch of the Bristol Aeroplane Co., Ltd., of Bristol, England.
