Application filed October 24, 1921. Serial No. 510,069.
T 0 aZZ whom it may concern:
Be it known that l, MANUEL CHARLES REYES, citizen of Mexico, residing at Madrid 21, city of Mexico, Mexico, have invented certain new and useful Improvements in Propellers for Aeroplanes, of which the following is a specification.
The object of this invention is to more efficiently utilize the power of a propeller in effecting ascent of an aeroplane and in aiding the travel of the same.
The invention seeks to provide means whereby a current of air will be caused to travel over the wing of an aeroplane or across the front of the machine and thereby create a partial vacuum relieving the wing or the aeroplane of atmospheric pressure to 'a'considerable'extent and permitting rapid progress of the machine.
The invention is illustrated in the accompanying drawings and will be hereinafter fully set forth.
In the drawings:
Figure 1 is a plan view of a plane having my improvements applied thereto,
. Figure 2 is a vertical section through an aeroplane propeller embodying the invention Figure 3 is a detail perspective view of the propeller and mounting therefor illustrated in Figures 1 and 2,
Figure 4 is a perspective view illustrating the invention applied to 'the front of an aeroplane,
Figure 5 is a detail section showing a slightly different form of the invention.
Fig. 6 is a perspective view showing another slightly difi'erent form of the invention.
In the drawings, the reference numeral 1 indicates a wing of an aeroplane upon which is mounted a casing consisting of side walls 2 which may rise from the edges of the wing or may be secured to or formed upon a base plate which, inturn, is secured upon the wing or plane. Extending between the upper edges of the side walls 2 is a base plate 3 disposed parallel with the wing or-plane and having its ends projecting beyon face of the walls 2, as shown clearly in Figures 2 and 3. Rising from the base plate 3 is a dome 4 of circular formation and rising from the dome concentric therewith is an annular rim or shell 5 which may be reinforced so as to resist any tendency to buckle, by radial bars 6, as shown and as will be readily the' 'through the top of the rim or shell and spread within the dome and forced out through the exits defined by the ends of the side walls 2 and the projecting ends of the base plate 3, to sweep in a flat sheet over the upper surface of the wing or plane 1, as in-, I
dicated by the arrows in Figure 2. This sheet of air sweeping over the plane or wing will relieve the same of atmospheric pres sure so that a partial vacuum will be created and, owing to the decrease of resistance and pressure upon the wing the aeroplane may quickly rise in a vertical path.
In Figure 4 T have illustrated the propeller shaft and its propeller mounted in a horizontal position upon a vertical plane or upon a part of the frame of the aeroplane, indicated at 9. In this form of the invention, the rim or shell 10 has its forward end open throughout its area, the reinforcing bars 6 being omitted so that there will be no obstruction to the inflow of air when the propeller is operated. The dome 11 is the same in all respects as the dome 4 and the base plate 12 and side walls 13 correspond in all respects to the base plate 3 and the side walls 2 respectively. In this application of the invention, when the propeller is rotated, a current of air will be created to flow inwardly through the shell or rim 10 and spread upwardly and downwardly in a flat sheet over the front surface of the vertically disposed plane or frame bar 9, so that ressure resisting the forward travel of t e aeroplane is minimized and, consequently, the machine may be propelled at a high speed with less power than has been possible with devices heretofore known to me.
- In Figure 5, I have shown the .form of the invention in which the dome 4 or 11 is omitted, the plane or wing 14 being provided with side walls 15 corresponding in all 'respects to the sidewalls 2 and 13 and the base plate 16 being disposed parallel with the plane or wing 14 and. projecting beyond the face of the side walls, as clearly shown. The rim 17 rises directly'from the base plate 16 at a right angle thereto so that the divergent walls provided by the dome in the previously described forms of the invention are omitted. The propeller blades 18 are dis posed within the rim 17 and are carried by a shaft 19 extending through the plane or wing and arranged concentric with the rim posts 22 so that the air blast may spread in all directions over the plane or the frame bar. The dome 23 corresponds in all respects to the domes 4 and 11 and is surmounted by a circular rim or wall 24, the pro eller being disposed concentrically within t e circular rim. The radial braci bars are omitted in this form of the device as will be readily noted, and they may be used or omitted as may be preferred.
In all forms of the invention, the propeller operates within a circular shell or rim so as to suck through thev open outer end thereof a current of air which will be caused to spread over the plane or wing, or frame bar of the vehicle in a flat sheet and thereby relieve the plane, wing, or frame asagna,
is claimed as new is:
- 1. The combination with a plane, of spaced parallel side walls rising from the plane, a tubular member carried byand above said side walls, and a propeller mounted within said member'and operable to drive air blasts over the surface of the plane from between the ends of the side walls.
.2. Thecombination with a plane, of parallel side walls projecting therefrom, a cir, Cular member carried by and over said side walls and having an open outer end, a propeller shaft extending through the plane into the circular member and arranged concentric with said member, and a propeller carried by said shaft within the enclosure and adjacent the outer open end of the same.
3. The combination with a plane, of side walls rising therefrom, a base plate secured to said side walls andprojecting beyond the ends thereof, a dome rising from said base plate, a circular shell rising from said dome and having an open outer end, a propeller shaft extending through the plane into the shell and arranged concentric with the shell,
and a propeller carried by said shaft within the shell and adjacent the outer open end of the same.
In testimony whereof I aifix my signature.
