Application led August 30, 1921. Serial No. 496,889.
To all who/mit may concern.'
Be it known that I, HARLIN G. FARMER, a` citizen of the United States, residing at Garnett, in the county of Anderson and State of Kansas, have invented certain new and useful Improvements in an Aeroplane, of which the following is a specification.
This invention relates to aeroplanes, and has for one of its objects to increase the stability and steadiness of devices of this character.
Another object of the invention is to provide a device of this character wherein provision is made for conserving the power of the motor and utilizing the lifting power of the propeller to increase the etliciency and preventing the propeller from interfering with the currents through which the plane passes.
Another object of the invention is to provide a device of this character wherein the parts are arranged so that the motor and other heavy parts are disposed substantially at the center of gravity of the aeroplane and thus conserve the movements.
With these and other objects in view and others which will be manifest and suggested as the nature and purpose of my invention are revealed in the ,following specication and drawing wherein I have shown a practical, yet preferred embodiment thereof.
In the accompanying drawings:
Figure 1 is a side elevation,
Fig. 2 is a plan view, and
Fig. 3 is a front elevation of the improved device.
Fig. 4 is a diagrammatic perspective view illustrating the arrangement of the control of the steering devices.
rI`he improved device comprises a supporting frame formed with vertical post members 10, horizontal brace or stay members 11, and obliquely directed brace wires or rods 12, of the usual aeroplane construction.
A floor portion 13 connects the lower ends of the posts and supports an operators seat 14. The floor 13 likewise supports a steering wheel 15 and winding drum 16, and the operating levers, one of which is indicated at 17, preferably operating over a toothed segment 18 of the usual construction, whereby the position of the lever may be retained.
A cupped plane or main wing member 21 is attached to the upper ends of the post members 10 and extends beyondv the same atv each end, and is supported by the usual brac-e rods 22.
Hingedly coupled at 23 to the main wing member 21 and extending rearwardly therefrom is a supplemental wing or plane 24, preferably formed with a compound or reverse curve as shown in Fig. 1.
l'ilxtendingy rearwardly from the frame members 10 and from the frame of the plane 21, is another frame represented as a whole at 25 and converging toward the rear and supporting the usual arrangement of steering wings 26.
Supported by the frame members 10 and 11 in any suitable manner is a motor, represented conventionally at 27, and arranged to operate a propeller, represented conventionally at 28.
It will be noted that the motor is located beneath the rear portion of the main plane or wing 21 with the propeller operating as close as possible to the under face of the wing, and nearer the rear than the front or forward edge of the main wing.
By this means the heavier portions of the plane, such as the motor and the weight of the operator are located substantially at the center of gravity, so that a balance is produced, which materially increases the stability and steadiness.
The steering wings 26 are controlled by the usual arrangement of pull cables or wires, indicated at 29, and leading to the winding drum 16, while the movable plane 24 is provided with suitable controlling wires or cables 30 leading over guide pulleys 31 and thence to the lever 17, as shown.
In the ordinary arrangement of the propeller relative to the wings or planes, or in advance of their forward lines, a relatively great amount of power is wasted by failing to utilize the force of the lateral air currents produced by the propeller. With the arrangement shown however, with the propeller rearwardly of the forward line of the lmain or stationary plane 21, and operating relatively close to its lower centra-l surface, the lifting power of the air out by the ing it much easier to control the movements.
It will be noted that the seat or the operator and the means for controlling the steering wings are located in advance of the line of the propeller, and also below the .of the same, thereby materially increasing the steadiness and buoyancy. Y
rThe power necessary to drive-the planevis also materially increased by' the arrangementshown. *l l v. 1 p v In the accompanying drawings, Ihave illustrated `my Ainvention yembodied .inllone formfby. ,Way @fieri-ample, and Which-impractcehasbeen felled t0 behelily Satsectory infobtainingthe desiredresults7 It willbe obvious however that other einbodinients may The, adapted, and that v,various changes in the details of vconstruction rnay be resortedto by thoseslilled the artwthout departing from thev spirit and scopeofthe invention.
