1 Claim.

5 vacuum; while at the same time producing a pressure at the rear from the exhaust of the air drawn through the device.

The principal employment of this invention will be for the propulsion of airplanes, airships,

l automobiles, and water craft, while in addition it may be employed for ventilation purposes.

I accomplish the objects of this invention in the manner described in the accompanying specification and drawings in which:

Fig. 1 is a front view.

Fig. 2 is a rear view of Fig. 1.

Fig. 3 is a side view of Figs. 1 and 2.

Fig. 4 is a side view of a modification having a part broken away to display the interior.

Fig. 5 is a skeleton view of the outer casing showing a preferred type of blade contained therein.

Fig. 6 is a skeleton view of the outer casing showing another preferred type of blade.

Fig. 7 is a front view of a further modification having part of the front of the casing broken away to display the blade arrangement.

Fig. 8 is a rear view of Fig. 7.

Fig. 9 is a vertical sectional view of the casing in Figs. '7 and 8 showing the blade arrangement contained therein.

Similar numerals refer to similar parts throughout the several views in which 1 is a cylindrical casing having at its front end a flange or the like 2 provided'with a central opening 3. r

The inner surface of the outer wall of the casing 1 has secured to it two or more blades 4 which blades are not at an angle of incidence The blades are also secured to the inner face of the flange 2.

Secured to the blades is a disc like member 5 preferably the same diameter as the opening 3. The disc 5 closes the center of the rear of jthe cylindrical casing 1 leaving an opening 6 between the disc and the outer periphery of the casing.

The disc 6 is mounted on a shaft 7 and retained thereon by the flanges 8 and 9 together with the rivets 10.

Referring particularly to Fig. 4, I may increase the length of the cylindrical member and provide an outlet 11 at the center of the rear, securing the disc to the blades 4 at the center -l of the cylindrical member 1 leaving a space 12,

at the rear of the disc causing the air to be discharged at a centrally located opening between the arrows 13.

Throughout the performance of my invention I may employ a blade arrangement as shown in Fig. 5 and Fig. 6 respectively or'I may employ a combination of fixed and rotating blades 14 as is illustrated in Figs. '7, 8 and 9, the functioning of which will be described later. While the device is shown attached to a shaft rotatable with the device I may provide the device with bearings and allow it to revolve on a fixed shaft.

Describing the operation of the invention, power is applied to the shaft '7 which rotates the device as a whole, the air within the device 9., is thrown by the blades from the center to the inner surface of the casing 1 where the centrifugal force of the air from the revolving blades thrown against the inner surface of the casing causes a pressure against the inner sur- 75 face and the flange 2 compelling the air to be discharged under pressure through the opening 6. The air discharged from the center of the device by the rotating blades causes a suction which in turn creates a vacuum immediately in front of the disc 5 drawing the device forward.

It will now be observed that the entire surface area is utilized to draw the device forward either from a pressure or vacuum.

Referring to Fig. 4 it will be noted that the disc is mounted on the blades as in Figs. 1, 2 and 3, but is located at the center of the device forming a pressure chamber 12 by the introduction of a flange 15 having an opening between the arrows 13 through which the air is discharged.

Referring particularly to Figs. '7, 8 and 9 it will be observed that I employ an outer casing having a flange at the front thereof, a disc substantially the same diameter as the opening in the flange, a blade or blades secured thereto, but in addition employ two or more blade arrangements 14 adapted to rotate on a center axis 17 secured to the disc 5.

In this particular application of my invention the operation is as has already been described relative to the intake and discharge of the air. The functioning of the blades 14 being as follows:

On rotation of the device as a whole in the 9? direction indicated by the arrow 18 air is drawn from the front of the center of the device and thrown towards the inner surface of the cylindrical casing 1 by the forward faces 19 of the blades 4. A pressure is created at the forward side of the blades 4 while a vacuum is created at the rear of the blades as at 20. The blades 14 are compelled to rotate in opposite direcinclined' surfaces 21 operating] behind the.

flange 2.

It will be observed that in the foregoing specification and drawings I have provided an airg, propelling device of such character that it, utilizes its entire surface area to producevac'uums and pressures from an airstrean rpassing; through itself for the purpose of forwardpropulsion.

Having now particularly described and ascertained the nature of my invention and the manner in which same may be performed what I claim as new and desire to secure by United States Letters Patent is:

In an air propulsion device the combination of a peripheral casing rotary around an axis, a flange at the front of said device and extended inward from said casing toward the .axis and having a central opening, a disc opposite to said opening, and arranged at the rear of said device, said disc closing the central part of the rear orithe device and having around it an air escape opening near the casing, and blades having surfaces parallel with the axis extending from said ,casing inward, and towards points which are at a distance from the axis of the device.
