IMPROVEMENT IN KITES.
Specification forming part of Letters Patent No. 117,270, dated July 25, 1871 antedated July 18, 1871.
To all whom it may concern:
` will render it lighter than the surrounding air,
which assists it in rising and sustains it in the air, although there may be little or no wind blowing at the time. The advantage of this arrangement is that the iirst part of the operation in tlying the kite is made less diiiicult, until it has risen a sufficient height to be moved upward by the current of air.
The accompanying drawing represents my kite in a perspective View, and is constructed as follows: y
A is the body of the kite, which is made of any suitable material, such as rubber, being made thin to give it lightness, and suiiieiently strong to resist the pressure ofthe gas within. At a a are left small pendants, to which the strings are attached, all of which converge to the point continuing from thence in a single strand. av1 al are flexible necks, communicating between the interior ofthe kite and the free air without. A string f or ine strong thread is tied around the necks all al after the gas has been let within to keep the kite closed. The body of the kite is divided into two lobes by the junction of the top and bottom walls, as seen at a? in the drawing. It may be necessary to connect the two walls by one or more additional connections, to prevent the kite from assuming too round a shape.
The operation of my invention becomes obvious. l When the kite has been lledwith gas, and the neck al secured, as described, it will be suflieently light to rise in the air without the necessity of drawing it rapidly along, as inthe usual way. It is not intended to depend on the lightness of the kite to elevate it to any great height, or more than will be enough to bring it in contact with the currents of air above the ground, at which place it will then be taken up further by the wind, as other kites.
The amusement thus offered to the young will be greatly increased bythe greater ease of starting the kite, and also its tendency to i'ly lighter, owing to its lightness compared with the surrounding air.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
A kite, constructed of two parallel walls connected by a strip of the same material and properly stayed to keep the kite-shape, `the space between the walls to be iilled with gas lighter than common air, substantially as described.
