A.Jackson Avro Aircraft since 1908 (Putnam)

Avro Curtiss-type

  In the summer of 1910 A. V. Roe and Company declared its willingness to build aeroplanes to other people’s designs and the first such aircraft was a Farman-type biplane for the Bolton business man and manufacturer of Avro aero engines, Maurice F. Edwards. Bolts, fittings and bracing wires were also supplied to Miss Lilian Bland who built and flew the Mayfly biplane of her own design at Carnamony, Belfast. Each of these aircraft was fitted with one of the few examples of the 20hp two-cylinder, horizontally-opposed, air-cooled Avro engines. The Farman-type evidently did not met with much success as 18 months later, at the end of 1912, the engine and airframe were advertised for sale in new condition for £45 and £60 respectively.
  A Curtiss-type, of the familiar outrigger-tail and front-elevator variety with 50 hp Gnome rotary, was built in 1911 to the order of Capt E. W. Wakefield of Kendal. Neither this nor the Farman-type mentioned above was given an Avro designation. Mainplanes were of unequal span and lateral control was by four ailerons on the upper mainplane, the inner and larger pair having semi-circular trailing edges. It was built at Manchester and delivered at Brooklands for test flying on May 25, 1911, though it did not fly until June 19.
  After a short period with the Avro School during which it was flown by F. P. Raynham, R. C. Kemp, F. Conway-Jenkins and Louis Noel, the Avro-Curtiss was dismantled on July 7, 1911, and transferred to Lake Windermere where Capt Wakefield replaced the wheels by a single 12 ft, three step, canvas covered mahogany float built by Messrs Borwick and Sons of Bowness-on-Windermere and small cylindrical floats were fitted below the wingtips. During the course of the re-erection and modification much dissatisfaction was expressed with the standard of the machine’s construction and over the discovery of a crack below one cylinder of the Gnome engine. Legal proceedings were begun against A. V. Roe and Company with Capt Wakefield claiming £212 for the engine and £50 on account of the Curtiss-type not being built to contract but there was no recorded outcome to the case. The aircraft made its first flight in marine form on November 25, 1911, piloted by H. Stanley Adams, a former pupil of the Avro School. The success of the first test flights prompted Wakefield to invite the press to view an exhibition flight two days later. The event was reported at some length in The Westmoreland Gazette and the reference to the machine’s bird-like properties are thought to have prompted the adoption of the name ‘Lakes Water Bird’ by which the machine was subsequently known. Water Bird was the first consistently successful seaplane in the United Kingdom and during the next few months its fame spread quickly and a considerable waterborne joyriding business was done. Sixty flights were made in the first 38 days, the best being of 20 minutes duration up to a height of 800 ft. On December 7, 1911, Stanley Adams flew the whole length of the lake at a speed of approximately 40 mph at a height of between 60 and 100 ft. These operations continued throughout the winter, but the night of March 29-30, 1912, brought gales which demolished the lakeside hangar at Cockshott and damaged Water Bird beyond repair. Its float, tailplane and rudder (the last still proudly displaying the legend ‘A.V. Roe and Company, Manchester’) are still in the possession of the Wakefield family at Windermere.
  Water Bird’s successor, identical, but entirely designed and built at Windermere by Capt Wakefield’s Lakes Flying Company later in 1912, was known as Water Hen. Its only Avro component was the airscrew and at first it could be distinguished from its Avro-built forerunner by the wingtip floats and straight trailing edges to the ailerons. These were mounted parallel to the chord line of the mainplanes instead of at a considerable angle to it. They were later remounted in the angled position but by that time more drastic modifications had been made and all similarity to Water Bird ceased.

    The gale which swept the country on Friday and Saturday accounted for the demolition of the hangar sheltering Captain E. W. Wakefield's two hydro-aeroplanes on Lake Windermere. In its collapse both machines were damaged, part of one of the planes being seen in our photograph of the wreckage protruding from the side. This incident, we presume, will be regarded as a score in their favour by the anti-aeroplanists of Windermere.
