Specification of letters Patent.

Patented Jan. I3, IQId.

Application filed January 16, 1913. Serial No. 742,417.

To all whom it may concern:

Be it known that I, Jon L. Rose, a citizen of the United States, and residing in Kansas City, in the county of Jackson and State of Missouri, have invented a certain new and useful Improvement in Aeroplanes, of which the following is a specification.

My invention relates to improvements in aeroplanes.

It relates particularly to the structure of a supporting plane of an aeroplane.

The object of my invention is to provide a supporting plane for an aeroplane which volplaning may be safely and easily effected.

My invention provides further a construc tion of supporting plane which will enable an aeroplane to soar and even to rise wlth the employment of the wind alone as a motive power.

My improvement is adapted to be applied to biplanes or monoplanes.

In the accompanying drawings, which illustrate a preferred embodiment of my invention as applied to a monoplane, Figure 1 is a perspective view of the aeroplane. lFlg. 2 is a cross section, enlarged, on the line a-J) of Fig.3. Fig. 3 is a view, partly in plan and partly in section of a portion of the aeroplane.

Similar reference characters designate similar parts in the different views.

1 designates the body of the aeroplane, which may be of any usual type and in the drawings being shown as the conventional body of a monoplane.

2 designates the wings or supportingplanes attached to'the body I at opposite sides thereof. The usual ailrons, not shown, may be employed. Each supporting plane 2 comprises a plurality of transversely extending plane sections 3 disposed, preferably, one in advance of the other, and each section, excepting the forward one, being arranged with its forward edges disposed higher than and separated from the rear edge of the section which is in advance thereof, as best shown in Fig. 52. Preferably, the sections 3 are each inclined forwardly and upwardly, and, preferably, the sections are disposed so that the plane 2 as a whole is forwardly and upwardly inclined. In the preferred form of my invention, each section 3 has a forwardly rising camber, the most eflicient form of the section being ogee in cross section, is, in the form of a reversely curved line with the camber portion, designated by d, at the forward portion of the section. Also in the preferred form of my invention the plane 2 as a whole has a forwardly rising camber, that is, the rear of each plane section lies in a common curved line denoted by the dotted line cd in Fig.

i 2. Suitable tie bars 5 disposed transversely to the sections 3 serve to retain them in their proper positions. Truss mechanism comprising truss rods 6 connected to the sections 3 and supported by vertical braces 7 mounted on the body 1 may be provided.

In volplaning or scaring, the wind passing against the camber portions 4: of the sections 3 will have a tendency to lift the machine, while the reversely curved portions of the sections at the rear of the camber portions t will tend to support the machine, the disposal of the sections so that the plane as a whole has a forwardly rising camber assisting in this function.

With the sections 3 spaced apart, as shown, each section will have directed upon it a portion of the wind which is not directed against the other sections, and after the wind has exerted its lifting effect upon the camber portion 4; it will then serve to act upon the portion to the rear of said camber portion for the purpose of supporting the machine. Thus by directing the machine with the usual guiding mechanism so that the axis of the machine will be inclined to the current of air, volplaning may be readily and safely accomplished, and with a suliiciently strong wind and suitable manipulation of-the guiding mechanism soaring may be accomplished, and even rising flight may be efiected without the use of engine power. Thus by holding the machine in a position at the right downward inclination to the wind, the camber portions 4 of the, sections 3 will, like kites, tend to lift the machine, and each section will be acted upon by comparatively fresh or undisturbed air, the result of which will be to lift the machine as a kite is lifted, the wind being sumciently strong for the purpose. In volplaning in still air, a like effect will be produced, that is a kite efiect, the forward movement of the machine serving as substitute for the wind.

I do not limit my invention to the structure shown and described, as modifications, within the scope of the appended claims, may be made without departing from the spirit of my invention.

Having thus described my invention, What I claim' and desire to secure by Letters Patent, is v 1. An aeroplane supporting plane having a plurality of transversely extending plane sections disposed one imadvance of and adj acent to the other, each section having a re versely curved under surface, the forward portion of which is concave and the rear portion convex, the rear of the plane sections lying in a common curved line. I

2. An aeroplane supporting plane having a plurality of transversely extending plane sections disposed one in advance of and adjacent to the other, each section inclining forwardly and upwardly and having a reversely curved under surface, the forward portion of which is concave and the rear portion convex, the rear of the plane sections lying in a common curved line.

3. An aeroplane supporting plane, having a plurality of transversely extending plane sections, disposed one in advance of the other, each section'inclining forwardly and upwardly, and having an under surface the forward portion of which is concave and the rear portion of which is convex, the front edge of a section being disposed higher than and separated from the rear edge of the next preceding section, the rear and forward edges of plane sections which are adjacent ,to each other being located closely adjacent to vertical planes which pass respectively between-said forward and rear edges, the rear edges of the plane sections lying in a conimon forwardly and upwardly curved line.

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