TU'EZ AEROPLANE.
' Specification of Letters Patent.
Patented May i0, i921.,
Application filed October 6, 192). Serial No. 415,131.
To aZZ whom t may concern:
Be it known that l, WILLIAM EDWARD Arrnnnr, of 79 Rosebery Crescent, Jesrnond, Newcastle-ou'lyne, England, a subject of the King of England, have invented certain new and usefui Improvements in and Relating to rloy Aeroplanes, of which the following is a specification.
rThe invention relates to model aeroplanes for use as toys and adapted to be made of paper, cardboard, or similar material. nlhe improved model may be designed to be sold as a complete unit or the parts thereof :may be severally printed in sections on sheets of paper or card and arranged to be cut out and stuck together by the purchaser to form the complete model.
lThe invention consists in providing a model biplane of this kind which is so formed that automatic stability is obtained, this being effected by arranging the tail plane and upper main plane at an angle of incidence of approximately t degrees to that of the lower main plane which is parallel to the line of flight, and by forming the nose of the model to give the effect of a lifting plane. A further feature consists in a particular manner of folding the leading edges of parts of the model, with a view to stiffening. the leading edges and also to obtaining a streamline effect.
ln the accompanying drawings illustrating' the invention Figure l is a plan view of the complete model.
Fig. 2 is a side view of Fig. l.
F ig. 3 is a cross sectional view to a larger scale, showing a leading edge folded according to the invention, and
Fig. i shows in plan the development of Fig. 3.
Referring to the drawings, a designates the fuselage to which are connected the upper and lower main planes, Z) 61 and the tail plane c, automatic stability being obtained by arranging the tail plane o and upper main plane b at an angle of incidence of approximately i degrees to that of the lower main plane b1, which latter is parallel to the line of flight, and by so forming the nose e of the fuselage a that it acts as a small liftlng plane, the nose having for this purpose a fiat face inclined upward and forward.
The main planes Z) 291, cabin f, chassis g, tail skid j, struts it, and other parts if desired, may all be stiffened at the leading edges by folding the same in the manner shown in Figs. 3 and e. rlhe front portions of these and any other parts to be folded are marked, as shown, with lines m, n, o on which the folds are to be made. he leading portion in front of line o is folded'back upon itself on this line, then folded in the reverse direction on the line n, carried forward and curled over the line 0, and brought underneath the section n 0 and folded back at m. The section a o is glued to the adj acent underlying portion and the section m p to its adjacent superimposed portion, thus producing the streamline spar or strut g.
To enable the flight of the model to be controlled the tail plane c comprises elevator portions i", and the main plane ailerons s, a rudder t being provided, said parts r, s and t being adapted to be bent about lines' u into the position required for the particular evolution.
VVhat l claim as my invention and desire to secure by Letters Patent of the United States is A. model or toy aeroplane constructed of paper, the leading edges of the wings being formed by folding back a portion of the paper, returning it over the leading edge, foldingin the end and connecting the surfaces in contact with the main body of the plane above and below.
ln witness whereof l have signed this specification in the presence of two witnesses.
