names filed Mal-0e22, 1920. Serial 'naeemsaf- T0 aZZwhom it may concern I Be it knownthat'l, ARTHUR E. Moran, a citizen of the United States, residing at Stillman Valley, in thecounty of Ggle and State of Illinois, have invented certain new and useful Improvements in Aeroplanes, of which. the following is a specification.
'This invention pertaining in general'to aeronautics, has more particular reference to aeroplanes, and especiallyto the control of lateral stability thereof. 1 The primary object of .my inventionvisto provide animproved and novel means for operating the auxiliary wing surfaces for the purpose of controllinglateral stability of the plane. Y n

ing and stabilizing effect of said wihgsurfaces.
My invention further contemplates the provision of a control means of the character described of much simpler construction than the ordinary wire controls now employed, and adapted tobc applied to any aeroplane having auxillary wing surfaces n I the form of flaps, ailerons or auxiliary wing tips such as employed in the present case. In furtherance of these general objects, I have provided a" lever interposed between and pivotally connecting the auxiliary wing surfaces and pivotally mounted medially upon the plane so that when rocked upon its pivotal mounting sald wing surfaces at 0pposite ends of the main wings will be raised and lowered inversely. This lever is connected with the main control member, in the present instance to the control stick, by means of which both lateral and longitudinal stability is maintained. By vertically adjusting the pivotal mounting of said lever the angle of incidence of the auxiliary wing Fig. 8, a fragmentary view looking for} *5 ward at the lever which: connectsthe aux iliary wing'surfaces at the opposite ends of.
the main wings, and showing the parts immediately connected to said lever; J Fig. a deta'il side view'ofthepivotal connection at the lower end of Fig. 3; I
" Fig. 5, a sectional view taken on the line 135* diagrammatic views illus trating different movements of the'lever con trol, which will be hereinafter. 1
improvements are applicable to any type of aeroplane, that is, irrespective of the number of'wings dlstlnguislnng such types, andin the present instance are'employed'in explained more fully connection with a 'bi-plane; For purpose" of clarity I have illustratedin" the drawing onlysuch parts of a planeas are essential i for an understandingof my present inven; tion'. These-parts consist of the, main upper and lower wings 11 and '12 respectively connected by suitable struts, and a j fuselage, :of
which only the bottom 13 ofthe cock pit shown. A- stick' control of conventional de sign is employed comprising the stick '14: pivotally mounted on'the horizontahrock shaft 15 to swing forwardly-andback wardly thereon, but to rock laterally-with said shaft. transverse rockshaft 16 equipped at its' ends with rocker armsf'17 connected in the usual manner with thefelevator flaps, is adapted to be' operated from the stick 14 through theagency of the f link connection 18. "The foot'lev'er 19 is adapted} to operate the rudder in the usual r'naimei,
' The auxiliarywlng surfaces ato'r nearithe ends of the main wings may be of any suitable/or preferred shape, proportions or dc-- slgn, and in the-present instance are .of'the same cross-sectional shape and dimensions as the main. wings. These auxiliary. wing surfaces 21 and 22 at opposite ends of the main wings are each pivotally attached to the latter adjacent to the forward edges thereof, as for example, by beingp'ivotally. ,7 mounted upon the front spars 23 which are rigid with and extend beyond-the main wings. The remainlng spars terminate at the outerendsof the'main'wings, so that the" auxiliary wing surfaces21 and22are free to swing vertically upon the front spars Struts 24conn'ect the upper and lower auxiliary wings ateach end ofthe planeso that p each pair will be held in parallel relationat all times. These struts 2e are joined by a horizontal lever 25 pivotally mounted upon a stud 26 medially between theauxiliary wings. This stud is present formed integral with a part 27 which threadingly engages and is supported by a vertical screw rod 28 suitably mounted for rotation but held against movementlongitudinally of its axis. Connected rigidly with the lever 1s a depending member 2 telcscopingly engaged with a part 81 whichis pivotally connected at 32 with an upstanding crank arm. 33 rigidly connected to the forward end of the rock shaft 15. By reason of the foregoing construction, it will be manifest that by swinging the stick 1% to the left, that is, in a counter-clockwise direction viewing Fig. l, the lever 25 will be r cked upon its mounting 26 in a similar direction, thus lowering the auxiliary wings 21 and raising the wings 22 for the purpose of causing the left end of the plane to dip, or for the purpose of maintaining lateralstability as is well known.
For the purpose of varying the angle of incidence of the auxiliary wings, the pivotal mounting of the main lever 25 may be raised or lowered by revolving the screw This may be done in'any suitable manner, as by means of a hand crank 34rconnected by means of a sprocket chain with the screw shaft 28. Y
In Fl 6 and T, the action is illustrated diagran'imatically, showing in the former the tilting of the main lever 25 about its pivot 26, and showing in the latter the pivotal point 26 raised, thereby lowering: the angle of incidence.
It is believed that the foregoing conveys a clear understanding of the objects prefaced above, and while I have illustrated and described but a single embodiment of my improvements, it should be understood that various changes might be made in the construction and arrangement without depart.
inc" from the sairit and sec cc of the anpended claims, in which I claim:
1. In an aeroplane, the combination of the main wings, auxiliary wing surfaces for the purpose of lateral stability, a lever pivotally connected at its opposite ends directly with .said wing surfaces and pivotally mounted outer ends of a main wing, coinprising;- a.
lever pivotally mounted medially between the ailerons and reaching; laterally and connected substantially directly thereto, and means for raising and lowering said pivotal mounting of the lever whereby to increase or decrease the angle of incidenceof both said ailerons. c
3. In an aeroplane, the combination of auxiliary wing surfaces for purpose of lateral stability, member connecting said wing surfaces and pivotally mounted inter mediate its ends, vertically adjustable means upon which said member is pivotally mounted, and manually operable means for adjusting said membersupportingg means vertically to uniformly change the angle of incidence of both wing surfaces.
4. In an aeroplane, the combination of auxiliary wing surfaces for purposeof .l= eral stability, a lever connected at its ends with said wing surfaces and adapted to rock. medially for changing the angle of incidence of said surfaces inversely, a vertical threaded member, means supporting and threadingly engaging said threaded member, and means for revolving; said threaded member for vertically adjusting the pivotal support of said lever.
