MOTOR FLYING-MACHINE.

Specification of Letters Patent.

Patented May 31, 1910.

Application filed August 27, 1909. Serial No. 514,867.

following to be a full, clear, and exact descri tion of the same.

y present invention relates to motor flying machines of the kind described in my prior application Serial No. 412,859 filed Jan. 27th, 1908 and has for its object to provide certain new and improved devices for controlling the discharge of compressed air. from the compression chambers which are closed on top and open at the bottom and the rear end, for the purpose of imparting ascending and forward movements as desired to the machine without stopping or checking in any way the movements of the rotating devices (wings, screws or the like), which draw air from the chambers which are open on top and closed at the bottom and compress it in the chambers which are closed on top and open at the bottom.

I will now roceed to describe the invention with re erence to the accompanying drawings, wherein:

Figure 1' shows a vertical longitudinal section through a compression chamber, the bottom of which is completely closed by the air-discharge controlling devices, while the rear end is open. Fig. 2 is a similar view showing the bottom of the compression chamber completely open and the rear thereof closed. Fig. 3 is a diagrammatical cross-section through suction and compression chambers with rotatory wings and Fig. 4 shows a similar section, with a screw in each side opening of the compression chamber.

My motor flying shi or machine is composed of a plurality of uxtaposed longitudi nal chambers 1 and 2, as described in speci= flcation Serial No. 412,859, the chambers 1 being 0 en on top and closed at the bottom, while 0 ambers 2 are closed on to and open at the bottom and rear end. Sai chambers communicate with each other by means of lateral apertures 3, in each of which is arra ed to rotate a suitable air-screw 4 (as a su stitute for the rotating wings 1' shown in Fi 3 and described in specification Serial o. 412,859), carried by the transverse shaft 5. The various shafts 5 are actuated by means of belts, chains or the like 6, passing around a common pulley 7, driven in any suitable way by a motor. The upper part of the air-ship, motor and motor appliances are preferably arranged on and supported by a suitable framework 8, preferably provided with a platform or platforms for the pilot and passengers. However this part of the machine does not form a part of my present invention.

The compression chambers 2, shown in longitudinal section in Figs. 1 and 2 are closed on top and the front and open at the bottom and the rear end as shown. The front portion of the bottom is preferably formed of an incline 9 serving to lessen the resistance to flight.

Journaled at the bottom of the compression chambers 2 are transverse shafts .10, each of which carries a flap 11 adapted to be adjusted and held in any desired position,

either for closing the bottom (Fig. 1) or partly or completely opening the same (Fig. 2). -At the rear of the compression chambers are journaled transverse shafts 12, each of which carries a flap 13, adapted to be adjusted and held in any desired position either for partly or completely opening {Fig 1) the rear end or closing the same Fig. 2).

The transverse shafts l0 and 12 are provided Wit-h levers 14: and 15. respectively,

and these levers are preferablyg connected to each other by suitable means 16, so that the bottom flaps 11 are closed when the rear flaps 13 are opened and vice versa. Said flaps may be adjusted in the desired position by means of hand-wheel 17, connected by means of a chain or the like 18 to a pulley or chain-wheel 19 arranged on one-of the transverse shafts 10.

The .devices described operate as follows :By the rotation of the air-screws 4 (Fig. 4.) air is drawn from the chambers 1 through the apertures 3 and compressed in the chambers 2, the bottom and rear flaps of the latter being closed. Now if the bottom flaps 11 are opened by turning the handwheel 17 the compressed air escapes downwardly from the chambers 2, whereby a correspondin reaction is produced on the top wall 20 0 said chambers (see arrows 21 in respondingly, so that the compressed air is allowed to escape obliquely and downwardly through the bottom and rear end, a corresponding oblique reaction being thereby produced on the front and top Walls of the chambers 2, so that the air-ship is raised in an oblique direction. lVhen the bottom flaps 11 are completely closed and the rear flaps 13 completely opened, the compressed air escapes only rearwardly (Fig. 2) and produces a corresponding reaction on the front wall 22 (see arrows 23 Fig. 1) of the chambers'2 for the straight flight of the machine; the sustentation of the latter is then secured by the incline t) and the surface formed of the closed bottom flaps 11, both gliding on the atmospheric air.

It is manifest that other suitable devices may be substituted for the flaps 11 and 13 to control the discharge of compressed air from the chambers 2 of the air-ship, Without departing from the scope of the invention.

Having fully described my invention, What I claim and desire to secure by Letters Patent is 1. In an air-ship of the kind described, the combination With a frame structure divided into parallel alternately disposed suction and pressure chambers, and means disposed in said pressure chambers for Withdrawing air from saidsuction chambers and compressing the same in the pressure chambers, of suitable controlling devices at the open bottom and the rear end of the pressure chambers capable of. controlling the discharge of air from the latter, and means for adjusting said controlling devices as desired, substantially as set forth.

2. In an air-ship of the kind described, the combination With a frame structure divided into parallel alternately disposed suction and pressure chambers, and means disposed in said pressure chambers for Withdrawing air from said suction chambers and compressing the same in the pressure chambers, of adjustable flaps arranged at the open bottom of the pressure chambers, similar flaps arranged at the open rear end of the latter, suitable means for connecting all the flaps so that the bottom flaps are closed When the rear flaps are opened and Vice.

versa, and means for adjusting the flaps as desired, substantially as set forth.

3. In an air-ship of the kind described,

the combination With a frame structure divided into parallel alternately disposed suction and pressure chambers, lateral apertures forming a connection between the latter, and a rotatory air-screw in each aperture, of suitable controlling devices at the open bottom and the rear end of the pressure chambers, capable of controlling the discharge of air from the latter, and means for adjusting said controlling devices as desired, substantially as set forth.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing Witnesses.
