Hornstein Biplanes Nos. 1 and 2
Two Hornstein-designed biplanes were constructed during 1910 by the Thames Bank Wharf Company. Both were light-weight pushers, but had different engines. No. 1 was fitted with the eight-cylinder 20 h.p. J.A.P.; No. 2 had the four-cylinder 35 h.p. Green. No. I crashed at the end of March, 1910, while under test at Halliford, Shepperton-on-Thames. Span. 32 ft. 9 ins. Wing area, 430 sq. ft. Weight loaded, 888.5 lb.

THE HORNSTEIN BIPLANE.
THE characteristic feature of Mr. Homstein's machine, on which he had a mishap on Sunday, is extreme lightness of construction, his argument being that, for experimental purposes at any rate, the greater number of advantages lie with such a system. An interesting detail is the use of cork pads as distance-pieces in the construction of the skids. Each skid consists of two thin strips of wood, set edge on to the ground and braced together by thin bolts passing through the cork pads, as shown in the accompanying sketch. This system of construction, although extremely light, is not very rigid laterally and the skids do not keep their shape very well, but it has been Mr. Hornstein's contention that anything capable of bending would be less liable to break, and therefore safer in the early days of experiments when it is generally a case of either bending or breaking something.
Mr. Hornstein's biplane has a span of 10 metres, and a chord of 2 metres, the supporting area of the main planes being thus 40 square metres. In front is a biplane elevator, having a span of 2.35 metres, and a chord of 85 cms. Two machines of approximately similar dimensions have been constructed, one being fitted with a Green engine and the other with a J.A. P. Chauviere propellers of 2.1 metres diameter and 1.6 metres pitch are employed. The estimated total weight of the machine in flight is 403 kilogs., including 193 lbs. for the pilot.
The ribs that stiffen the fabric of the main planes are also of unusual construction. They have a modified T section, as shown in the accompanying sketch, and are steam bent to the required curvature.
Mr. Hornsteinfs Accident.
AMONG the many British flyers who have been quietly experimenting in England is Mr. Hornstein, who on Easter Sunday met with a mishap while flying on a private ground at Halliford, near Shepperton-on-Thames. On the previous Friday Mr. Hornstein had flown a mile and a quarter at a height of about 40 ft., and it was from about the same height that the machine came down suddenly on Sunday, apparently due to a mistake in steering. Mr. Hornstein was pinned beneath the machine, and sustained injuries to the head. He has for some time been designing machines that have been constructed by the Thames Bank Wharf Co., and has recently been experimenting with the biplane with which the accident occurred. Elsewhere we give a few details of the machine.

Mr. Hornstein's Good Friday Flight.
SOME further particulars have been given to us by an independent eye-witness concerning the flight which was made by Mr. Hornstein with his machine on Good Friday, and about which - as also his unfortunate accident on the following Sunday - we reported in brief last week. It seems that there were at the time plenty of spectators about, to all of whom the outstanding feature of the performance was the remarkably high rate of speed that was maintained. Apparently a run of about 25 metres was taken before actually leaving the ground, and then the distance travelled was 21 kiloms., at a height varying between 12 and 18 metres from the ground. Amateur clocking credited the time taken as being but 48 secs., though needless to say this is entirely unofficial as a record - such as it would seem to constitute.
Ground was regained in a ploughed field, on to which the machine alighted without sustaining injury of any kind, and this particular machine, which is one of those that Mr. Hornstein has built in England, is equipped with an 8-cyl. Jap engine of 35-h.p. On a new machine which he has in course of construction, a trial is to be given to an 80-h.p. engine of Italian origin that has a special system of air-cooling embodied in it.
