Application filed April 22,

To ZZ whom t may concern:

Be it known that Gianni CAPRONI, engi* neer, subject of the Kingdom of taly, residing at Milan, Via Durini No. 24;, Italy, has invented certain new and useful llmprovements in Flying-ll/lachine Constructions, of which the tollowing is a specication.

The invention relates to improvements in flying machine constructions and particularly refers to multiplanes having for its object to reduce the resistance or the air against the 'iront cell or wing during flight.

lVith this object in view, the invention consists in the new arrangement lot the cables wherein the purpose isy to maintain only the diagonal cables in the structure of the cell.

The object of the invention will be better understood with reference to the annexed drawing giving, by way oi example, a form oiz the construction otl the invention as applied to the triplane.

Fig. l'is a iront view ot an aeroplane, showing the arrangement which constitutes the invention.

Fig, 2 is a perspective view ot central unction means connected with the` invention.

Fig. 3 is a plan view oi'l the means as represented in F ig. 2.

Fig. l is a side sectional view or the same means.

Similar characters ot references designate corresponding parts throughout the several views.

Referring now more particularly to the accompanying drawings there is provided a triplane of the knock-down type including the front central cell l which has detachably connected thereto the side cells or wings -2-2-, one of the latter being shown disconnected for the purpose of clarity. These cells or wings comprise longitudinals -3-3- and 3- connected at suitable intervals by uprights 4c.

Cables 5--5- are provided while a central junction piece 6 is employed to receive one of the ends of each of said cables.

A fuselage 7 is connected with the front cell and in turn has connected thereto a landing carriage 8. The lateral cells or wings -2-2- are symmetrically connected to the central cell 1 while the longitudinals are tied to one another by means Specicaton of Letters Patent., `Taft-glitt@d` May. 16,` 192,2;

of the uprights a and diagonal cables- 5- so as to form a rigid and resistive structure.

The cables -5- stretched between points -9 and the upper ends l0 of one of the uprights e gives the side cells or wings the necessary horizontal stability.

The central junction piece -6- consists of a tie -lljournalled and fastened on the medial longitudinal 3- each tie being provided vwith a hemispherical casing l2 which is kept in place by-a flange 13 resting on the longitudinal and embraced by the turned down rand or iiange 15 of the said tie. f

rlhis latter construction is such that the casing may be turned and the casing is in turn provided with radial holes l5- 5 which receive nipples i4- the heads l5 of which are anchored within the casing l2 while the outwardly projecting portions of the nipples are threaded internally for `receiving the corresponding threaded adjacentv ends ot the diagonal cables -5-. The casing is further provided with hole 1G- for giving kpassage to the uprights t.

Having now particularly described the nature of my inventionL and the manner in which the same should be performed, I claim l.l An aeroplane structure comprising a plurality of superposed planes including ak plurality ot longitudinals, a plurality of up# rights extending vertically from one longitudinal to the other, a plurality of staywires extending between the ends of said uprights and crossing each other in groups on points of the medial longitudinal, a hemispherical casing having its base connected to said medial longitudinal, and means for connecting the staywires to the casing.

2. An aeroplane structure comprising a plurality of superposed planes including a plurality of longitudinale, a plurality of uprights extending vertically from one plane to the other, a plurality of staywires extending between said uprights and cross`- ing each other in groups on points of said longitudinals and said uprights, hemispherical casing having a flanged base itted against the medial longitudinal, a stirrup surrounding the medial longitudinal and embracing the flanged base so as to permit or turning of the casing, said stirrup being fastened on a longitudinal in proximity of of holes in which the headed nipples are an upright, and headed nipples anchored anchored. 10 in said casing to receive the adjacent ends In testimony whereof I alixed my signaof said staywires. ture in the presence of two Witnesses.
