This invention relates to improvements in airplanes, an object being toiprovide means capable of being included in the structure of an airplane, which will increase its lifting olane to be operated with greater eciency at low, as well as high flying speeds.
As is Awell lmown, the airplane obtains its greatest lift from the vacuum created upon the top of the wing, and it is the purpose of the present invention to increase the height or depth of this vacuum space by providing vertical walls of upwardly traveling air lwhich extend above the wing and which act to draw the air between these walls upward, and as the' walls of air meet at a point above the wing, the up r surface of the latter is divided into a numy er of relatively high vacuum cham- "eers or spaces.
Another object of the invention, is the provision of means of the above character which may also be utilized to provide opposed resistance walls to materia ly assist 1n stabilizing the airplane, while these resistance walls applied to the ailerons and rudders, will give control of the airplane at low, as well as hi hil gspeeds.
itglilhe above and other objects in view,`
the invention further includes the following so novel features and details of construction, to
hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claim.

views taken respectively on the lines 3-3 and 4-4 of Figure 1. iure 5 is a plan view showing a slightly modi ed form of the invention.
Figure 6 is a view similar to Fi re 2 but illustrating the form of the inventlon shown in Fi re 5.

of an airplane 4from which extends a wing or wings 11. The horizontal and vertical rudders of the airplane are indicated at 12 and 13 while the ailerons are shown-at 14. 5 power and control, and will permit the air- All of the foregoing elements may be of 5 any preferred material and of suitable shape and size, the invention residing in providing combined lifting and resistance means for the elements mentioned which will increase the lifting tate control atlow ying speeds.
With the above purposes in mind, the invention provides spaced elongated slits 15 in the wing of the plane and in Figure 1 of the drawin these slits are disposed in the as ggfs: The slits 15 extend throu h e wingV and are formed by opposed si e disposed asane is in flight sages, which, when the air s of air upwardq'o will direct currents or wal above the upper surface of the wing. This upward movement ofv these air currents will create a suction and the air currents meetingy at a point above the upper surface of the wing form separate or individual vacu chambers or vacuum spaces of an appreciable depth so that the vacuum ordinaril?I emsting over the upper surface of an airp ane wing in flight will be materially increased due to the depth or height of thesevacuum chamso bers or aces. By this means, the lift of the win wi be materially increased and the airp ane may be supported and controlled at lower flying speeds than is ordinarily posslble. In addition, the walls 16 of these pasas sa es offer resistance to tilting so that the I sta ility of the plane is increased.
y providing these passa es and walls 1n the ru ders 12 and 13, as in icated at117, increased -airresistance is offered by the rud; eo 1 ders when the latter are manipulated, so that the direction ofl i ht of the plane may be more readily contro led at low 'ng speeds.
In addition, the provision of t e increased lifting power provlded under the upper suro5 face of the wmg wing camber so that the wings offer less re- In Figure 5 of the drawings, the wing 18 and ailerons 19 have the slots disposed longi- 1D0 power of the airplaneand facilii permits of a reduction in Y' Y .tudinallyas shown at 2O so that longitudinally disposed air walls and liftirilg1 chambers are rovided for the wings and erons.
e horizontal and vertical rudders 21 and 5 22 are provided respectively with laterally and upwardly extending slots 23 and 24 to oier resistance for the control of the plane.
The invention is susceptible of various chan es in its form, proportions and minor deta` of construction and the right is here'- in reserved to make such changes as pro erly fall within the scope of the appended c aim.
Having described the invention what is claimed isz- In an airplane, a wing including upper and lower walls having relatively narrow spa slots and the slots of one wall alinin with vthe slots of the other wall, and sp pairs of strips connecting the upper and lower walls and formin air passages in alinement with the alining s ots of the walls, said. slots disposed in the direction of Hight of the de vice to divide the upper surface of the wing into separate vacuum chambers during the iii ht of the airplane.
testimony whereof I aiix my si ature.
