Used to be in the Hungarian Follies until the Soviet government of Austria picked her up to place the imitation English money that its presses were striking off in Vienna." IV. The Cambered Foot I shall not pretend that I knew the man in America or that he was a friend of my family or that some one had written to me about him.
Stolen hours he gave to the building of box-kites with cambered wings, after rapturously learning, in the autumn of 1908, that in August a lanky American mechanic named Wilbur Wright had startled the world by flying an aeroplane many miles publicly in France; that before this, on July 4, 1908, another Yankee mechanic, Glenn Curtiss, had covered nearly a mile, for the Scientific American trophy, after a series of trials made in company with Alexander Graham Bell, J. A. D. McCurdy, "Casey" Baldwin, and Augustus Post.
The German is a stout enemy, and when we beat him with a machine he sweats till he has invented a new one. They have great pilots, but never so many good ones as we, and I do not think in ordinary fighting they can ever beat us. But you must watch Lensch, for I fear him. He has a new machine, I hear, with great engines and a short wingspread, but the wings so cambered that he can climb fast.
The double surfaced planes were to be built with wooden ribs and arranged with a slight dihedral angle; there was to be a large aspect ratio and the wings were cambered as in Stringfellow's later models. Provision was made for warping the wings while in flight, and the trailing edges were so designed as to be capable of upward twist while the machine was in the air.
The Wrights had known of this tendency from Lilienthal's researches, but had imagined that the phenomenon would disappear if they used a fairly lightly cambered or curved surface with a very abrupt curve at the front.
The third year advanced a man to the nice points of the trade such as the foreign bonds Flemish, Dutch, Roman and Old English; cutting and turning of arches of all kinds, straight, cambered, semi-circular, three centred elliptical, and many forms of Gothic and Moorish arches; also brick panels and cornices. Finally it gave practice in the laying out of plans and work from these plans.
'Nobody ever had a foot cambered like that, or with a heel like it, or with toes like it. Somebody made those prints with his hand the edge of his palm for the heel and the balls of his fingers for the toes. The wide, unstained distances between these heelprints and the prints of the ball of the toes show the impossible arch. "Sir Henry was like a man gone to pieces.
Here, instead of being cambered as it ought to be, the soffit is straight; but the brickwork being deep, there is room enough for a true arch that does the work, and for useless material to hang from it. These arches are generally rubbed or axed, and are very common at the openings of ordinary windows.
But as he tramped out on the flying-field he began to run at the sight of two wide, cambered wings, rounded at the ends like the end of one's thumb, attached to a fragile long body of open framework. Men were gathered about it. A man with a short, crisp beard and a tight woolen toboggan-cap was seated in the body, the wings stretching on either side of him. He scratched his beard and gesticulated.
"Sure!" said the Pharmacy man. "How would you make one?" "Why uh I guess you could make a frame out of willow have to; the willows along the creeks are the only kind of trees near here. You'd cover it with varnished cotton that's what Lilienthal did, anyway. But darned if I know how you'd make the planes curved cambered like he did. You got to have it that way. I suppose you'd use curved stays.
