fiML /%4 absorbers, is provided with fl single throw between the floats. By operating the crank, d, through the cable, J, and the tube, e, the wheels are raised and lowered. „._,..£- n.„ The folding chassis of the Fluguugbau Frudnchshafm biplane is shown in Fig. 4. It is built up of steel tubes and bears every evidence of being a substantial job. From a small hand wheel near the pilot's seat the cable, s, passes round a pulley down to the lever, a. Another cable connects the other end of the lever, a, with the trigger, c The release of this trigger by means of the cables allows of the upper triangle, d, being swung round its fulcrum, e, thereby lifting the lower triangle, /; and the wheel up against the ® ® A Slipway for Seaplanes. CONSILIKRAHI S interest is being aroused by the experiments which are being made at Hue with an arrangement, designed by M. Bleriot, primarily for launching seaplanes when the sea is too rough for this operation to be carried out. The apparatus consists of steel cable about 90 yards long, suspended horizontally from a special arrangements of masts. While attaining its flying speed the machine would be suspended from this cable and on reaching the end would be released. At the end of a flight the machine would be piloted under the cable, and elevated until an arrangement at the top of the (atom gripped the cable. It will be remembered that some time ago Ucnn Curtiss conducted some experiments in launching aeroplanes from an elevated cable, but in that case the aeroplane was above the cable. The idea was suggested to M. Blenot by watching the difficulty expeienced by some of the pilots at Monaco in getting their machines off the water. Aeroplages at Hardelot. THE three days' meeting for sand-yachts held at Hardelot, on Saturday, Sunday and Monday, resulted in a complete success, and already plans are under way for organising similar meetings at JULY 26, 1913. lower plane. Springing is effected by means of coil springs con- US flSliSSf'll two main floats, each of which is provided with a pair of Wheels, as shown in Fig. 5. The wheels are mounted on a crank situated just behind the step of the float. The tube, c, is connected at its lower end to the crank, which carries the wheels and at fts upper end to the cross member, gt to which are secured the shock absorbers, e and/ The cross member, g, b accom modated in a slot in the steel stamping, h, which is secured to the flsat by means of steel bands. The chassis of the Shock monoplane differs from those of the other machines in that provision has teen made for raising and lowering, not the wheels, but the floats. The way in which this operation is carried out is clearly shown in Fig. 6. The floats, which are of circular cross section, are raised by means of the cables, a and b, which pass over the drums, c and d. These latter are revolved by means of the crank, c, to the right of the pilot's seat. Turning the crank in one direction raises the floats by swinging them outwards and upwards round the fulcrum formed by bringing the float struts to the fuselage. They can be lowered again at will by turning the crank, <?, in the opposite direction. The results of the races were as follows : — The Lake Constance Prize.—1. H. Hirth (Albatros mono plane), time, 1 hr. 46 mins. 17 sees. 25,000 mark and Grand Duke of Baden's prize. 2. Rob. Gsell (Friedrichshafen biplane), time, 1 hr. 46 mins. 5 1 sees. 10,000 mark and prize of Minister for Public Works. 3. R. Thelen (Albatros biplane), time, 2 hrs. 8 mins. 5,000 mark and prize of Secretary of State for Navy. 4. W. Kieszling (Ago biplane), prize of the Constance Verkehrsverein. The Amateur Race.—I. Hans Vollmoller (Albatros mono plane), time, 48 mins. 50 sees. 5,000 mark and Kaiserl. Auto- mobil Club's prize. 2. Kohnert (Friedrichshafen monoplane). Consolation prize of 2,000 mark and Count Zeppelin's prize. Prizes for Construction,—I. Albatros monoplane, Pilot Hirth. 5,000 mark. 1,316 points. 2. Ago biplane, Pilot Kieszling. 3,000 mark. 1,315 points. 3. Friedrichshafen biplane, Pilot Gsell. 2,000 mark. 1,308 points. Climbing Tests.—1. Hirth (Albatros monoplane), 500 metres in 11 "6 mins. 3,000 mark. 2. Kieszling (Ago biplane), 500 metres in i2-8 mins. 2,000 mark. Starting and Alighting Tests.—Hirth, Thelen, Kieszling and Gsell, 1,000 mark each. Vollmoller and Faller, 800 mark each. Kohnert, Bauerlein and Strack, 500 mark each. Prizes for Mechanics (500 mark each).—1. Hirth's mechanic. 2. Hirth's mechanic. 3. Vollmoller's mechanic. ® ® various other French seaside resorts. Of the 43 entrants some 29 took part in the racing on Saturday, although the boisterous wind caused the postponement of all racing until the after noon. The course was one kilometre round and had to be covered five times, the winner of the final turning up in B. Dumont on a Dumont, whose time was 12 mins. 45 sees., while F. Dumont was second. On Sunday there was a race from Hardelot to Ste. Cecile and back, a distance of 13 kiloms. The first five places were secured by Dumont machines, B. Dumont being the winner in 56 mins. 20 sees. Alfred Leblanc and Emile Dubonnet on Bleriots were seventh and ninth respectively. There were two items on Monday, the first a race for ladies with gentle men passengers, while in the second the pilots were of the sterner sex with lady passengers. In each case the course was to Equihen and back, a distance of 8 kiloms., the ladies'race being won by Mme. Crespelle on a Dumont, with Mme. Wattine also on a Dumont a good second, and Mdlle. Dormain on a Bleriot, third Droeschout on a Dumont won the gentlemen's race in 11 mins. 40 sees, with Acker on a Dumont second, and G. Dubois on a machine of his own design, third. 822
