CHARLES E. REDMAN', OF CHICAGO, ILLINOIS.
AEROPLANE.
Specification of Letters Patent.
Patented Mar. 29, 1921.
To all whom it may concern:
Be it known that I, GHARLns F. REDMAN, a citizen of the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Aeroplanes, of which the following is a specification.
My invention relates to improvements in aeroplanes, and has for its object the production of a device of this character which will be of durable and economical construction, eflicient in use, and which will afford a maximum safety to an aviator in using the machine.
Other objects will appear hereinafter.
The invention consists in the combinations and arrangements of parts hereinafter described and claimed.
The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in which,
Figure 1, is a top plan view of an aeroplane embodying the invention,
Fig. 2, a side elevation thereof,
Fig. 3, an enlarged section taken on substantially line 3-3 of Fig. 1,
Fig. 4, a central vertical longitudinal section through the front end of the aeroplane,
Fig. 5, a section taken on substantially line 55 of Fig. 4,
gig. 6, a front elevation of the aeroplane, an
Fig. 7 a front elevation of a slightly modified form of the aeroplane.
The preferred form of construction, as illustrated in the drawings, comprises an elongated body 10 mounted on wheels 11 and 12 arranged at the front and rear ends, respectively, of said body. At the front end of said body is provided the usual powerdriven propeller 13. Rigidly secured to and projecting laterally from the front end of body 10 are supporting planes 14 of the usual transversely arched formation.
Formed in the opposite sides of body 10, directly below the planes 14, are circular openings 15 in which are rotatably mounted circular or disk-like holders 16 held therein by flanges 17 and 18 secured to the opposite sides of the side walls of body 10. Ball bearings 19, as clearly seen in Fig. 5, are employed to alleviate friction and insure free and easy rotary movement of the mem;
bers 16 when the same are unlocked, as hereinafter set forth.
Rigidly connected with and projecting laterally from the holders 16 are supporting planes 20 which are thus arranged directly below and parallel with the planes 14. The longitudinal ribs or frame members 21 and 22 of said planes 20 project through the holders 16, as clearly seen in Figs. 4 and 5, the inner ends of alining ribs being overlapping and rigidly connected together by bands 23 and set screws 24, as clearly seen in Fig. 5, in order to rigidly connect the holders 16 and hence the planes 20 at opposite sides of the machine so as to insure rotative movement of said planes in unison with each other. Said planes are also of arched formation, with the concave sides thereof facing downwardly. Said planes are reinforced by reinforcing frame-work arranged below the same and which is formed by longitudinal bars 25 secured in and projecting outwardly from the holders 16, the bars 25 being connected at intervals with the planes 20 by upright posts 26 and diagonal brace members 27. The inner ends of the bars 25 are overlapped and rigidly connected together in the same manner as the bars 21 and 22 above described, and as clearly shown in Fig. 5.
The outer ends of planes 20 are rotatably supported by bearing members 28 in which are mounted the outer ends of plane bars 21. The bearing members 28 are interposed in posts 29 which depend from planes 1.4, diagonal brace rods 30 also connecting the bearing member 28 with the planes 14 for reinforcement. Diagonal brace members 31 also connect the outer ends of. planes 14 with the lower end of post 29, and brace bars 32 project inwardly from the lower ends of said posts to posts 33 depending from the front end of body 10. A structure is thus formed which is substantial, well braced, and hence one possessing great strength and durability, and well adapted to withstand the severe strains of wind pressure during the flying operation.
l Vith the construction set forth it will be seen that the planes 20 are mounted so as to permit of free rotary movement about axes disposed longitudinally, below and in the medial plane thereof and transversely of the body of the aeroplane. Such rotative movement of said planes may be manually 244. AERONAU'TICS 2. An aeroplane comprising a body; holders rotatably mounted in the sides of said body in axial registration with each other; laterally projecting planes carried by said holders; means for locking said holders against rotation and simultaneously freeing said holders for rotation; a pair of laterally projecting tail planes arranged at the rearward end of said body and mount- 10 ed to swing upon axes extending longitudinally of said body; and means for simultaneously swinging said planes on said axes, substantially as described.
