- Construction of the Bicycle
The accompanying engraving will convey to the mind of the reader a correct idea of the French two-wheeled velocipede. The majority of makers in this country fashion their machine upon this pattern in every essential respect. We append a full technical description. A is the front wheel. This is the steering wheel, and upon its axis, the power is applied. B is the hind wheel; C, the treadles or foot-pieces ; D, the treadle cranks; E, slots in cranks, by which to adjust the foot-pieces and accommodate the length to the legs of the rider; F, bifurcated jaw, the lower part of which forms the bearing for the axle of the front wheel. From the upper part of this jaw, a rod or pivot extends, to which is attached the steering arm or handle F; G, the reach or perch, extending from the jaw of the front wheel to the rear or hind wheel. This reach is bifurcated, forming jaws for the hind wheel. H, " rests" on the front part of the reach. The rider puts one leg on the rest and works one of the cranks with the other leg while riding " side-saddle," or a leg may be placed upon each rest when the velocipede has acquired sufficient momentum, and the rider does not wish to keep his feet upon the treadles. I, the saddle or seat, which is adjustable on the seat-spring L, by the thumb-screw K. The seat-spring L, is attached at M to the reach G, which, at the other end, is fastened to the spring-struts N, that rise from the reach G; 0, the brake-lever, on the fulcrum P; Q,, the " shoe " of the brake that acts against the periphery of the hind wheel. The brake is operated by means of the cord S, one end of which is attached to the steering handle F, and the other end to the reach at 3. A cord passes from the steering handle under the pulley or roller 4, thence over the pulley 5, on the brake-lever 0, and from there to the point 3, where it is attached to the reach G. The brake is operated by giving a slight turning motion to the handle F, thus winding a small sheave upon the axis of the handle, and bring-ing the shoe Q, of the brake-lever 0, in contact with the surface of the wheel B. - Control platform of an Airship

Leonardo da Vinci, who was a gifted engineer as well as an artist, devised a flying gear for man which shows some dynamic improvement over the mechanism of the old-time angels, flying gods, and hobgoblins. As shown in the accompanying sketch, it provided for gravitational balance by use of an expanding tail projecting well to the rear. Moreover, the propulsion was to employ both arms and legs. This design is considered very remarkable for the time in which it was produced, probably a few years before the discovery of America; and yet it is but one of Da Vinci’s quaint aëronautical inventions, as will appear later. - Da Vinci’s helicopter
Da Vinci’s second flyer was a helicopter. An aërial screw 96 feet in diameter was to be turned by a strong and nimble artist who might, by prodigious effort, lift himself for a short time. Though various small paper screws were made to ascend in the air, the larger enterprise was never seriously undertaken. Many subsequent inventors developed the same project; but the fellow turning the screw always found it dreadful toil and a hopelessly futile task. Of late the man-driven helicopter has been abandoned, but the motor-driven one is very much cultivated. Scores of inventors in recent years, aided by light motors, have been trying to screw boldly skyward, and some have succeeded in rising on a helicopter carrying one man. - Da Vinci’s parachute
Da Vinci’s third scheme for human flight, was a framed sail on which a man could ride downward, if not upward. This device never fails to navigate with its confiding sailor. Sometimes he lands in one posture, again in another; but voyage he must, with the certainty of gravitation. Leonardo is, therefore, the father of the parachute. This, in turn, has had a varied offspring. The common parachute, the aërial glider, the soaring machine, or passive aëroplane, that rides the wind without motive power and without loss of energy. - Daedalus and Icarus
The story of Dædalus and Icarus also tells us that man believed flying was somehow possible. Dædalus was a very clever man who lived with his son Icarus on the Island of Crete. The king of this island requested Dædalus to build a labyrinth or maze for him. Dædalus constructed the labyrinth so cleverly that only the king, who had the clue to the winding passages, could find his way out. One day the king became very angry at Dædalus and threw both him and his son Icarus into the labyrinth, intending that they should perish. Dædalus, who had been dreaming of flying, fashioned wings from wax and feathers, with which he and Icarus could fly to freedom. He cautioned Icarus that he must not fly too high or the sun would melt the wax in his wings. Icarus, impatient to escape, scarcely listened. Like birds the two flew into the air, quickly leaving the walls of the labyrinth. Dædalus, flying low, safely crossed the sea and reached Sicily. Icarus, unfortunately, failed to heed his father’s warning. Flying was so much fun that he rose higher and higher. Suddenly feathers began to drop one by one. Too late Icarus realized that the sun had melted the wax in his wings. Down, down he fell into the sea. - De Bacqueville
A method of flying was suggested as long ago as 1744, by the inventor De Bacqueville; his plan was to fix four planes or wings to his hands and feet, and then propel himself through the air by vigorous motions of his arms, and kickings of his legs. He made a flight from a balcony overlooking a river, but finished his trial ingloriously by falling into a barge. Such schemes, indeed, were doomed to failure; and they are only interesting because they show how, even in those far-off days, men were ready to risk their lives in attempts to conquer the air. - Diagram comparing the Pioneer with the Columbia

The ripping panel, invented in 1844 by America’s foremost pioneer aëronaut, John Wise, is a simple and an excellent practical device. This is a long patch running longitudinally above the equator[8] of the balloon, feebly sewed to the envelope, and having a cord, called the “ripping cord,” extending down to the car along the outside or inside of the bag, so that the pilot on coming to earth can let out the gas quickly by tearing a rent in the balloon, thus flattening it promptly on the earth’s surface, so as to avoid dragging and bumping if any wind prevails. - Diagram of Curtiss Aeroplane, side view

A "No. 2 flying boat," just built by Mr. Curtiss, and successfully tested on Lake Keuka, Hammondsport, in July, 1912, is the "last word" in aviation so far. An illustration in this book, made from photographs taken in mid-July, 1912, shows fully the bullet-shape of the "flying fish." It is a real boat, built with a fish-shaped body containing two comfortable seats for the pilot and passenger or observer, either of whom can operate the machine by a system of dual control, making it also available for teaching the art of flying. All the controls are fastened to the rear of the boat's hull, which makes them very rigid and strong, while the boat itself, made in stream-line form, offers the least possible resistance to the air, even less than that offered by the landing gear upon a standard land machine. Above the boat are mounted the wings and aeroplane surface. In the centre of this standard biplane construction is situated the eighty horse-power motor with its propeller in the rear, thus returning to the original practice, as in the standard Curtiss machines, of having a single propeller attached direct to the motor, thus doing away with all chains and transmission gearing which might give trouble, and differing from the earlier model flying boat built in San Diego, California, last winter (1911-12), which was equipped with "tractor" propellors propellers in front driven by chains. The new flying boat is twenty-six feet long and three feet wide. The planes are five and a half feet deep and thirty feet wide. It runs on the water at a speed of fifty miles an hour, and is driven by an eighty horse-power Curtiss motor. At a greater speed than this it cannot be kept on the water, but rises in the air and flies at from fifty to sixty miles per hour. - Douglas A-20B & C

Drasina This novel vehicle, under the name of " Drasina was introduced into England in 1818, and, at first, the greatest possible expectations were created, with regard to its usefulness and speed. It was maintained, that it would travel up-hill on a post-road as fast as a man could walk ; that on a level, even after a heavy rain, it would average six or seven miles an hour ; and that, on a descent, it would equal a horse at fall speed. It was described in the advertisements of the day as " consisting of two wheels, one behind the other, connected by a perch, on which a saddle is placed as a seat. The front wheel is made to turn on a pivot, guided by a circular lever or rudder, which comes op to the hand; the fore-arms rest on a cushion in front ; in this position, both hands holding the rudder firmly, the machine and traveller are preserved in equilibrio. In 1821 Lewis Gomperta of Surrey, introduced some decided improvements upon the Drasina , as will be seen from the accompanying engraving. The object of the improvement of Gomperta was to bring the arms of the rider into action, in assist-ance to his legs. It consisted " in the application of a handle, C, which is to be worked backwards and forwards, to which is attached a circular rack, D G, which works in a pinion, E, with ratch wheel on the ont wheel of the velocipede, and which, on being pulled by the rider with both hands, sends the machine forward; and when thrust from him does not send it back again, on account of the ratch, which allows the pinion to turn in that direction, free of the wheel. H is the saddle, and the rest, B is so made that the breast of the rider bears against it, while the sides come around him at some distance below the arms, and is stuffed." The rider could with this machine either propel it entirely without the feet, or he could use the feet, while the arms were free. The beam, A, was made of beech wood, and a pivot at F, allowed the front wheel to be turned to the right or left at the will of the rider. - Drawing of 1885 Benz engine

In the picture the operator is seen in the driving seat; and near him will be observed the motor which drives the craft. In his left hand—that is to say in the one nearest us—he grasps the lever which operates the elevating planes. The rod from lever to plane can be seen, and the motions the pilot makes are these: should he wish to rise, he draws the lever towards him and tilts up the elevating planes in the manner already described, increasing the lifting power of the main-planes and so causing the machine to ascend; by a reverse movement of the lever—by pushing it away from him, that is to say—he makes the craft glide downward. - Driving-seat of a touring plane

Dropping off in parachute from flaming balloon - Dunne inherently stable Biplane
Another machine which is stable in flight, owing to the peculiar formation of its wings, which resist a diving or plunging movement, or a lateral swing, is the Dunne biplane—as designed by Lieutenant J. W. Dunne. This craft is seen in the figure. Using such a machine, pilots have flown for long distances with the control levers locked, the biplane adapting itself automatically to the wind-gusts and preserving its equilibrium without aid of any kind. It has neither fore-plane nor tail; it is made to ascend by elevators which are in the form of hinged flaps, or ailerons, and is steered by two rudders at the extremities of the main-planes. A.

Giffard was succeeded in France, first by Dupuy de Lome; then by Gaston Tissandier, well-meaning projectors of steerable balloons, but too cautious to effect an important advance in the art. The first of these gentlemen, an eminent marine engineer, in 1872, completed a gas balloon for the French government, resembling the one designed by General Meusnier in 1784, and like that also driven by muscular power actuating a screw, and kept rigidly inflated by use of an internal balloon, or ballonet. The car was suspended from the bag by a close fitting cover instead of a net, in order to lessen the resistance, and it was kept in alignment by use of crossed suspension cords. A speed of but six miles an hour was attained by the industrious work of eight men operating an ample screw propeller. A decade later Tissandier, with a balloon of like design, but driven by the power of an electric motor and bichromate of potash battery, attained a speed of six to eight miles an hour. - Duryea Automobile
Description of first trip in the car When I got this car ready to run one night, I took it out and I had a young fellow with me; I thought I might need him to help push in case the car didn't work…. We ran from the area of the shop where it was built down on Taylor Street. We started out and ran up Worthington Street hill, on top of what you might call "the Bluff" in Springfield. Then we drove along over level roads from there to the home of Mr. Markham , and there we refilled this tank with water. [At this point he was asked if it was pretty well emptied by then.] Yes, I said in my account of it that when we got up there the water was boiling furiously. Well, no doubt it was. We refilled it and then we turned it back and drove down along the Central Street hill and along Maple, crossed into State Street, dropped down to Dwight, went west along Dwight to the vicinity where we had a shed that we could put the car in for the night. During that trip we had run, I think, just about six miles, maybe a little bit more. That was the first trip with this vehicle. It was the first trip of anything more than a few hundred yards that the car had ever made. - Early type of Smack
Early type of Smack For the fisheries a multitude of smaller types were constructed—such as the lugger, the shallop, the sharpie, the bug-eye, the smack. - Early-type Airship
A typical craft, representing the first of those navigated with any certainty, is shown in Figure. A gas-containing envelope, made of a light, strong, varnished fabric, is kept taut by the pressure of the gas within; the car, constructed of wood or metal tubing, is suspended by ropes from the envelope, and contains engine and crew, with a two-bladed propeller revolving astern. Such a machine, in its control, had an elevating-plane and rudder, upon the same principle as those of the aeroplane. One of the difficulties to be overcome was the expansion and contraction of gas in the envelope owing to differences in altitude and temperature. When the craft ascended, its envelope completely inflated, the gas began to dilate owing to the outer air becoming less dense; and some had to be allowed to escape through automatic valves. Then, should the machine descend to a lower level, there was not sufficient gas in the envelope to keep it tightly stretched, and it tended to sag at the bow as it was driven through the air. A.

- English one-wheeled Velocipede
We present an engraving of an English one-wheeled velocipede. The feet are placed on short stilts, connected with the cranks, one on either side of the rim, while the rider sits upon a steel spring saddle over the whole wheel. The inventor modestly limits the diameter of the wheel to twelve feet, and the number of revolutions to fifty per minute. Twenty-five miles per hour is the speed expected to be reached. The riders of this machine, without the ability to overcome the laws of gravity, would be very likely to get broken bones and noses. It is not likely to come into general use. - Fairchild PT-19

This lightship is anchored off Fire Island, near the southern coast of Long Island, U. S. A. Lightships sometimes mark shoals, and sometimes mark the entrances to harbours. They are always kept anchored in given spots and are merely floating lighthouses, although, of course, they are sometimes relieved by other lightships so that they may undergo repairs. - First attempts
Of the doings of another of these brave but reckless men—a Saracen who tried to fly in the twelfth century—there is fuller information. He provided himself with wings which he stiffened with wooden rods, and held out upon either side of his body. Wearing these, he mounted to the top of a tower in Constantinople and stood waiting for a favourable gust of wind. When this came and caught his wings, he “rose into the air like a bird.” And then, of course, seeing that he had no idea of balancing himself when actually aloft, he fell pell-mell and “broke his bones.” People who had gathered to watch, seeing this inglorious ending to the flight, burst into laughter: ridicule rather than praise, indeed, was the fate of the pioneers, even to the days when the first real flights were made. - First flight engine, 1903

A favorite trick of the slaver, fleeing from a man-of-war, was to throw over slaves a few at a time in the hope that the humanity of the pursuers would impel them to stop and rescue the struggling negroes, thus giving the slave-ship a better chance of escape. Sometimes these hapless blacks thus thrown out, as legend has it Siberian peasants sometimes throw out their children as ransom to pursuing wolves, were furnished with spars or barrels to keep them afloat until the pursuer should come up; and occasionally they were even set adrift by boat-loads. It was hard on the men of the navy to steel their hearts to the cries of these castaways as the ship sped by them; but if the great evil was to be broken up it could not be by rescuing here and there a slave, but by capturing and punishing the traders. - Flight of Princess Ermengarde
Carriage used about 1300-1350 in Flanders. Carriages were in use on the continent long before they were employed in England. In 1294, Philip the Fair of France issued an edict whose aim was the suppression of luxury; under this ordinance the wives of citizens were forbidden to use carriages, and the prohibition appears to have been rigorously enforced. They were used in Flanders during the first half of the fourteenth century; an ancient Flemish chronicle in the British Museum (Royal MSS. 16,[9] F. III.) contains a picture of the flight of Ermengarde, wife of Salvard, Lord of Rouissillon. - Flying Yankee Velocipede
HEMMING'S UNICYCLE, or "FLYING YANKEE VELOCIPEDE." The single-wheeled velocipede has at length received a palpable body, and " a local habitation and a name." Richard C. Hemming of New Haven, Conn., invented the machine herewith represented, two years ago; but has only recently brought it into the market and applied it to practical purposes.. The main wheel has a double rim, or has two concentric rims, the inner face of the inner one having a projecting lip for keeping the friction rollers and the friction driver in place; each of these being correspondingly grooved on their peripheries. The frame on which the rider sits, sustains these friction wheels in double parallel arms, on the front one of which is mounted a double pulley, with belts passing to small pulleys on the axis of the driving wheel. This double wheel driven, as seen, by cranks turned by the hands. The friction of the lower wheel on the surface of the inner rim of the main wheel is the immediate means of propulsion. A small binding wheel, seen between the rider's legs, serves to keep the bands or belts tight. The steering is effected either by inclining the body to one side or the other, or by the foot impinging on the ground, the stirrups being hung low for this purpose. By throwing the weight on these stirrups, the binding wheel may be brought more powerfully down on the belts. Over the rider's head is an awning, and there is also a shield in front of his body to keep the clothes from being soiled by mud and wet. When going forward, the driving wheel is kept slightly forward of the centre of gravity by the position of the rider. By this means the power exerted is comparatively small. Every turn of the crank is equivalent to a rotation of the great wheel. Mr. Hemming says that this machine can be manufactured for fifty dollars, of a weight of only thirty pounds;- that it will ascend steep grades, and that it can be driven on the roads with but little exertion, at the rate of twenty or even twenty-five miles an hour. This wheel is of a diameter of from six to eight feet. Mr. Hemming's boy of thirteen has one five feet in diameter, the first manufactured, crude in construction, and heavier than necessary, which he propels at the rate of a mile in three minutes. - Folsom Power House
- Forlanini’s helicopter, 1878
A still more ambitious helicopter was that shown invented by Professor Forlanini, an Italian Civil Engineer, and launched in 1878. The lower screw was fastened to the frame of a steam engine, the upper screw was attached to the crank shaft. Steam was supplied from the globe shown beneath, which was two thirds filled with water, and well heated over a separate fire just before an ascension. As the globe was merely a reservoir of hot water and steam, carrying neither fuel nor furnace, its power waned rapidly. The best flight lasted about twenty seconds, attaining a height of 42 feet. The apparatus weighed 77 pounds, spread 21.5 square feet of screw surface, and lifted about 26.4 pounds per horse power.
