Page 3 - If any light and flat, or nearly flat, article," he wrote, "be projected edgeways in a slightly inclined position, the same will rise on the air till the force exerted is expended, when the article so thrown or projected will descend; and it will readily be conceived that if the article...
Page 3 - ... conceived that if the article so projected or thrown possessed in itself a continuous power or force equal to that used in throwing or projecting it, the article would continue to ascend so long as the forward part of the surface was upwards in respect to the hinder part, and that such article, when the power was stopped, or when the inclination was reversed, would descend by gravity only if the power was stopped, or by gravity, aided by the force of the power contained in the article if the...

Page 71 - PHOTOGRAPHIC camera is suspended to a balloon, which is held captive by a rope containing three insulated wires. A tail is provided to keep the balloon in its proper position. A current passing up by the first wire causes a clockwork apparatus, attached to the camera, to actuate rolls holding the sensitive film in such a manner as to bring a fresh portion of the film behind the lens after an exposure has been made. A current through the second wire actuates the shutter, and the third wire acts as...
Page 71 - BALLOON PHOTOGRAPHY." A PHOTOGRAPHIC camera is suspended to a balloon, which is held captive by a rope containing three insulated wires. A tail is provided to keep the balloon in its proper position. A current passing up by the first wire causes a clockwork apparatus, attached to the camera, to actuate rolls holding the sensitive film in such a manner as to bring a fresh portion of the film behind the lens after an exposure has been made. A current through the second wire actuates the shutter, and...
Page 81 - Flexible leverarms extend on either side, and a flexible spar extends from the tail end of the body. Silk or other suitable fabric is extended from the arms and along the spar of the tail, thus giving a large supporting surface, and vibrations are imparted to the area which propels the machine by a wave-like motion.
Page 85 - ... PAUZE, Alfred. (Provisional only.) " FLYING MACHINE/' This framing is covered with oiled silk or other suitable covering. A large aeroplane is balanced on a mast situated in the car, and the said aeroplane can be inclined either up or down. Propellers are mounted on ball-and-socket joints, and can thus be employed for steering as well as for propelling. The car is mounted on springs connected to wheels, and the machine, when started on a level road, rises on the aeroplane being inclined upwards....
Page 18 - ... pole. The bow of the car is connected to two lines passing over pulleys on the tops of two other poles, and a weight is attached to the other ends of these lines. By releasing the trigger, the lines at the bow are pulled forward by the weight descending, and the machine receives a great forward velocity. The machine then becomes free, and speed may easily be sustained by turning the aerial screw.
Page 116 - The car carries two propellers, which are actuated by two motors, and by driving the propellers at varying speeds the balloon may be guided to the right or left, or the steering may be performed by a rudder. The vertical direction of the balloon is regulated by an adjustable weight, or by increasing or decreasing the speed of the propellers. The lifting-power of the balloon alone is not sufficient to cause an ascent, so that it is only when the propellers force the machine ahead, causing the balloon...
Page 65 - KITES." KITES are employed for suspending a person in the air for military purposes. The kites, which, if desired, may be provided with a frame , are held in tension from the ground by three or more ropes instead of one rope as has hitherto been the case. (Drawings.) AD 1875. No. 289. SIMMONS, Joseph, and MORRIS, Joseph Matthew. (Provisional only.)
