FLYING MACHINE.

Application filed June 12, 1926.

My present invention relates to improvements in flying machinespf the heavier- -than-air type and utilizing tunnels for directing pneumaticjets to the propeller wheel in order that the air may be condensed for action thereon by the propeller blades, there by increasing the propelling force of the propulsion he tunnels in the form of funnels are embodied chine, and fashioned with upper and lower,

approximately flat faces for maintaining the-f fore-and-aft equilibrium of themachine, and the usual or. standard steering apparatus and control devices are employed forsteering and stabilizing the machine in flight.

The invention consists in certain novel.

1 'c'on'ibin'ations and arrangements of parts as will hereinafter be more fully set forth and claimed.- In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention in an aeroplane wherein the parts are combined 5 and arranged-according to the'best mode lhave thus far devised for the practical application of the principles of my invena whole by the nu- 2, cabin space 3 for space 4 are alined from front to rear in the fuselage, with the aft of the freight.

Two supporting planes, indicated as a whole by the. numerals 7 and .8 are located at the right and left sides of the fuselage and aflixed thereto in suitable manner, and the right and left ailerons 9 and 10 project ing laterally from the lower faces of the respective planes 7 and 8 are cdntrolled from the cockpit by suitable control devices indicated by theletter C. These ailerons are hinged at their forward edges to complementary fixed balance wings'll and 12 at the right and left sides respectively of the inamechanism of the flying machine.

chine and rigid with the lower two supporting planes 7 and 8. 7

At the extreme rear of the machine is provided a standard vertical rudder l3 under control .of devices manipulated from the faces of the i cochpit, and the right and left elevators l'lndica'ted as 14 and -15 respectively are located in horizontal planes at the sides of the vertical rudder, which as shown in Figure 2 is notched to permit the required movement of the elevators.

The usual forward running gear 16 and rear running gear 17 are employed for land-' I n'g purposes and for supporting the machine while not in flight.

planes 7 and 8 are fashwhich are separated by the interposed fuselagel, (which iscyl'indrical or circular in cross section); areopen at their larger forward ends, The fuselage forms the inner adjoining walls of the funnels, and the outer, rounded, side walls 20 are obliquely arranged with-relation to the longitudinal center of the machine or ship, and converge therear of the propeller 6. t their converging orsmalle'r-ends the two funnels merge into a single, circular opening-21 at the rear of the motor or power 'plant, and a cylindrical casing 22, which encloses the propeller wheel is formed as a rear extension of the converging funnels or tapering tunnels.

By this construction and arrangement of the tapering tunnels or equidistant in a horizontal plane at the sides of the longitudinal center of the machine, the-air'currents'are caused to pass into the larger frontopen ends'of single, cylindigieal rear outlet for the funnels. he converging .walls 20. of the funnels direct the air currents into the propeller casing 22 and the passage of .the currents through the space of diminishing cross area results in is acted on by the creasing the propelling After the plane is in chine is flying as resistance area of the machine and permit greater speed, it is sometimes desirable that the functions of the funnels or tapering tunnels be suspended. 'For this purpose the outer side walls 20 of the funnels may .be

The hinges are located at the front or near the front edges of the tunnels, and these hinged side Walls may be opened in suitable manner and be permitted to swing outwardly as indicated by dotted lines in Figure 1 to a vertical plane parallel with the longitudinal center of the machine. In this position the side walls of the tunnels ofier but slight resistance to the air currents and the latter pass through the open front of the tunnels and outto the openings in the oblique side walls of the funnels, thus materially reducing the quantity of air currents directed to the proeller casing and lessening the density of air in the casing.

Having thus fully described my invention,

What I claim as new and desire to secure by Letters Patent is:

1. The combination in a flying-machine with its central longitudinally extending fuselage of lateral supporting planes forming funnels at the sides of the fuselage and the rear through provided with open front and rear ends, said rear ends merging into a single opening, and a propeller casing the opening as an extension of the funnels.

2. The combination in a flying-machine with its central longitudinally extending fuselage, of lateral, tapering tunnels at the sides of the fuselage each having an outer oblique wall converging to the rear of the machine, and a circular propeller casing forming an extension of the tapered rear ends of the tunnels. i

r 3. The combination in a flying machine with its central longitudinally extending fuselage, of laterah'tapering tunnels secured at the sides of the fuselage and forining'sup porting planes for the machine, saidtunnels having oppositely disposed oblique outer walls and openings therein, hinged closures for said openings, and a propeller casing forming an extension of the tapered rear ends of the tunnels,

In testimony whereof I aflix my signature.
