P.Lewis British Aircraft 1809-1914 (Putnam)
Hamble River, Luke H.L.1
The H.L.1 was built by Hamble River, Luke and Co., of Hamble, Hants., and was shown in an unfinished state at the 1914 Olympia Aero Show. It was a two-seat pusher seaplane designed by F. Murphy, who had worked previously as a designer with the British and Colonial Aeroplane Co., at Bristol. The machine featured a finely-finished cigar-shaped nacelle, at the rear of which was mounted a 150 h.p. N.A.G. six-cylinder German-designed and British-built engine, the radiators being fitted to the inter-plane struts on each side of the nacelle. The construction was of wood and fabric, and the wings were equipped with ailerons. The float structure was redesigned while the H.L.1 was being completed, and the machine was test-flown by E. C. Gordon England. Span. 60 ft. Wing area, 678 sq. ft. Weight empty, 1,600 lb. Weight loaded, 2.550 lb. Maximum speed. 65 m.p.h. Landing speed, 32 m.p.h.

HAMBLE hydrobiplane HL.l (Hamble River, Luke & Co., Hamble, Hampshire)
Constructed by an established boat building company, to the design of Frank Murphy, late of Bristol, the machine was shown incomplete at Olympia in March 1914. Changes were made later and the machine was tested by Gordon England, but costs were excessive, and the machine and the premises were put up for sale by July 1914.
The aircraft was a large two-seater pusher seaplane with twin wooden main floats and twin metal tail floats, moving with the rudders. There were four pairs of interplane struts each side, with radiators mounted on the innermost pairs. Ailerons were fitted to both top and bottom wings, the latter having pronounced dihedral.
The spruce tail booms, to be replaced by steel tubes later, extended aft from the second interplane struts. The tailplane and elevator were carried on the top booms, the pair of rudders pivoting on posts below. The pointed nose nacelle, was covered with two layers of cedar, laid up diagonally over the structure, and was mounted on short struts between the wings. The main floats were of similar construction, but rendered watertight, and were mounted on a steel tube chassis, intended to be sprung later.
Power: 150hp NAG (British-made) six-cylinder inline, water-cooled driving a Normale pusher propeller direct.

WHAT THERE WILL BE TO SEE AT OLYMPIA.
THE EXHIBITS.
Hamble River (Hamble River, Luke and Co.). (68.)
ON the stand of the Hamble River, Luke and Co. will be shown a seaplane which, whilst following standard lines as regards its general arrangement, is interesting from the point of view of construction. The nacelle, as will be seen from the accompanying sketch, is of cigar shape, and carries at its rear end a 150 h.p. N.A.G. engine. The main floats, of which there are two, are of rather novel design, and incorporate in their construction several new and interesting features. For the design of this machine, we understand Mr. F. Murphy, formerly connected with the British and Colonial Aeroplane Co., is responsible, and, although this machine has not as yet been tried, there is little doubt but that it will give a good account of itself in the future, and thus become a valuable addition to the list of British seaplanes.

THE OLYMPIA EXHIBITION.
THE EXHIBITS.
HAMBLE RIVER (HAMBLE RIVER, LUKE AND CO.).
UNFORTUNATELY the seaplane exhibited on this stand was not completely finished at the opening of the Show, and the temporary wiring up of the machine was hurriedly done, so that it is to be feared that a great number of the visitors received an unfavourable impression of the quality of workmanship in it. This is much to be regretted since it is the first time the machine has been shown in public and the workmanship is really very good. When one or two minor alterations have been effected and the machine has been properly tuned up, there is little doubt but that it will give a good account of itself.
In its general arrangement, the seaplane follows standard practice, being a biplane of the "pusher" type and having two main floats and two tail floats. The upper main plane is straight whilst the lower plane is set at a very pronounced dihedral angle in order to provide ample clearance when the machine is rolling.
The two main floats are built up of two skins of cedar, the inner one of which is laid on diagonally over a framework of spruce and rock elm. The floats are divided into watertight compartments by double bulkheads, and a layer of canvas, soaked in varnish, is placed between the two skins. All the chassis struts carrying the floats are steel tubes, and it is intended, we understand, to provide springing of the floats by means of telescopic tubes and coil springs.
The cigar-shaped nacelle is of similar construction to that of the floats, and provides accommodation for the pilot and passengers. The seats are arranged tandem fashion, and the pilot controls the machine by means of a single vertical lever and a pivoted foot-bar. In the rear of the nacelle is mounted the engine, a 150 h.p. British N.A.G., which drives directly a Normale propeller.
The tail unit is carried on an outrigger consisting of four tail booms of spruce connected by struts of the same material. These booms, one gathers, will later be replaced by steel tubes in order to provide a more rigid structure. The undivided elevator is hinged to the trailing edge of a fixed, non-lifting, stabilising plane, under the ends of which are mounted the twin rudders. Two small metal floats support the tail planes when the machine is at rest.
