mlm/T01? WHQL C. LL /0777 ffl/7744 .To all wle/omit may ccf/wem Be it linoivii that ,PAUL @E liimo'cr, citizen oli the Ulti ed lStates, a resideiit of Lawrence, iii the county ot lljoiiglas and State of Kansas, have made certain ii t and use-itil lmpioveiaehts iii Cu ving Ribs ior the Supporting-Surfaces ot ilieroplaiies, oi which the following is a speciiicatioh. n
My invention ielates to impr vements iii aeroplaiies, .and particularly to e supporting iibs oi'the planes thereof, ot that type which may be curved, or theciirve eliminated at the will of the operator, my object being to provide ribs oi certain structure vwhereby the suppoitihg beams ot' the pleite may be utilized, to affect the desired curvature of the rib, by the said supporting beams.
in cariyizog out this and othei objects l may utilize several structures, oit which the protected are shown in the accompanying drawing torming part ot this specification, and iii Which- Figure l is a sectional side elevatiori, showing a rib oi certain stiucttiie, 'together with portions of the supporting beams ih section and in operative cohhectioii with thel rib. 2 is a l plait vievl oit che device slioivh iii Fig. il, 8 is a detail vertical section therethrough. talteii on the liiie oi Fig, 2, Fig. l is a view similar to v illustrating a hoodited structures, ati-d Fig, is an enlarged verti l section siibstaii tially oh line 5-5 ci Fig., t.
Referring how to these tigtiies, and paiam ticularly to Figs. i to 3 inclusive, .l vipiovide rib composed ot two strips A amd l ,d formed of wood, metal or other suitably flexible material, and connected by a plurality oi vertical.- trahsverse connections C, spaced apart throughout the length ot the strips A and l, and so associated theievvith as to compensate for a diti'erehce iri linea-i' motion between such strips when the iib is curved more or less or the curve entirely eliminated. .To this end the several connecting mem# bers C are preferably secured toene of the strips and loosely engaged with the other strip, @ertain ci these connecting members at spaced points, and particularly indicated at C are substantially enlarged, and pron vided with squared transverse bores through which are extended the sup ortihg beams E and l, it being seen by re ereiice to Fig. 3, L that these connecting members C are se fipeciicatioh of 'Letters Pal rality ot i curedto the lovver strip B, and loosely enm seen that when the rlhds, it will be beams vD E are rotated in relatively op "posite dit/actions, the eilect will to either sirecl.
increase oi: decrease the curvature the rib, ahdriii order to eliminate the neces y of applyihg such rotative movement to both oi" thesiipportihg beams, il may provide them with double cranks d and e, the upper end of each oi these craiils being connected to the lower end oi" the othei ciahl by a cohhectirig rod F, Thus, the rods l? cross, as
shown iii l? l and 2, arid effect the desired f similar manner, the s G aiid irl oit the forth 5 ate each rovided v id clips, these clics result. lower st and spectively seen atg and it, and be cmihected by virtue ot slots iiiy through which portions oi the c i is .lt pass i'iivoider tto-compensate tor the di 'ereiice iii linear motion betweehL strips G and itl', as before stated. Ceitaiii of the clips li in this oim of iiiveiitioii have equated openings through which the similar shaped supporting ll and d lpass, these supportiiig beams having i vvaidly and' down- Wardly projecting Cral iis respective f which are connected by a rod lh this manner l accomplish the desired result so that it is at once simple edective, eliminates all possible iiiteriteiehce with other parts of aii i aeroplane ih cohhectioii with which improved rib and structiiie is to be utilized.
Y'The particular means li have shov/ii, vvhile capable ot' .considerable variation, are especially desirable iii that they be. applied to ahy machine embodying a supporting or sustaining suttace iii the mature ot a plane, and on ordinary types oic machines clips it they may be substituted tor those already iii use.
l`he caiiiber can be changed fromv a .straight liiie'to any iiecessary curve and in in rising from the ground and alighting` is greatly increased, (3d) the machine can be more quickly raised from the ground, and (4th) the' carrying capacity of the machine greatly increased. It is also to be understood that the plane or planes lon both sides of the machine may be simultaneously curved.
I claimzl. In a structure of the character described, lthe combination of a supporting rib and supporting beams, the former of which consists of upper and lower strips and a lplurality of connecting members rigidly connected to one of the strips and loosely engaging the other strip and throu h certain of which connecting members t e said supporting beams are fixed, and connections between the supporting beams for causing their rotation in relatively opposite directions.
2. In a structure of the character described, the combination of a flexing rib,`
and supporting beams fixed ,'at spaced points to the rib and constrained to rotary move-- nient in relatively opposite directions.
3. In a structure of thecharacter' described the combination of la1 supporting rib, consisting of upper vand lower flexing strips, and' connections between thesaid, strips to permit flexing movement thereof, and supporting beams non-rotatably extended through certain of said connections and constrained to rotary movement in relatively opposite directions, for the purpose described. y
4. In a structure of the character de# scribed, the combination of a supporting rib consisting of upper and lower strips, and a plurality of connections between'the strips to permit of their flexing movement, certain of. said connections having squared'apertures, and squared supporting beams extending through the squared apertures of the said connecting members, and constrained to rotary movement in relatively opposite directions.
5. In a structure of the character described, the combination of a supporting rib consisting of upper 'and lower flexing strips, and a 4plurality .of connections between the strips to permit-vof their flexing movement, certain or said connections having squared apertures, squared supporting beams extended through the squared apex.'- ture's and provided with crank arms projecting in relatively opposite directions, and a connecting rod' extending between the ends of the crank arms whereby to constrain the supporting beams to rotary movement in relatively opposite directions, all for the purpose described.
