To all whom it may concern:

330 it known that I, Lotus Bnr'inro'r, engineer, citizen of the French Republic, residing at 56 Boulevard-Maillot, Neuilly-sur- Seine, France, have invented certain new and useful Improvements in Aeroplanes, -of which the following is a specification.

This invention. relates to aero lanes and has for its object to improve bet the general arrangement and the detail construction of these apparatus.

The invention will be readily understood from the followingdescription of an aeroplane to which, the said invention; has been applied, in its ent1rety,i ;w1th,,the BSSISWDOG the .accomrganying drawings, which 1 are given merely y way of :example, read :the various figures of which will be referred to as required. j

in the draw1ngs: Figure 1 Isa side eleration, with parts broken; away, lllustratin an aeroplane of the monoplane type in whl the features of the resent invention are incm orated; Fig. 2 1s a detail plan view ofa lon ing skid structure which is rovidedat the rear end of the aeroplancyig.-2 3;is a plan view of the aeroplane as an entirety; ig. 4 is a front elevation thereof; Fig. 5 is a transverse section through the tail of the aeroplane; Fig. 6 is a simi ar view illustrat: ing a modification; Fi 7 is a detail view showing one of the lat s 0, to be hereafter described, in detached relation; Fig. dis a diagrammatic Ian. view of the construction shown in Fig. and discloses the brackets b at one side of the tail aseatauded and in operative relation to the correspondin lath o, and at the other side ohthe tail as olded pad disconnected from, the corresponding at 0.v 1

Similar characters of. reference designate corresponding parts throughout the several VIOWB. i Y m As will-bcecen-fromFigsa'l and 5,1the

z body is formed of ,fourlongitudincl memit ms a, those two which are intended-toform bottom of the said body being rectilinear i elevation and the two others, which are etcnded to form the upper iacooi the said ly, are arranged res actively exactly mvc the, lower ones, and cat and connected to the latter in such manner that the depth of said body considered from front to rear thereof first increases slightly then decreases quickly so as to become fairly small, and finally remains practically constant, or more accurately, decreases very slowly until it isreduced practically to nothing. Inthat way, it is possible to reduce toa considerable extent the head resistance. As alsoshown in Fig. 1 the body is divided into two elements one of which the rear ele ment, carries the tail and the horizontal and verticalirudders, andthe other, the front elementcarriesthe othereparts'of the aeroplane... These two elements are connected as shown inFig. 1 b such means as-to enable them to take up ifi'ercnt inclinations relatively to each other. The connecting means may conveniently comprise simple hinge fee tenings between the arts of the lower members 'a andadjustab chinge fasteningsbetweemtheupper members a, said adjustable hinge ifastenings including in each instance a removable hinge pin and a sector-like part having a rowof openings through any selected one 0 which the hinge pin may-be passed.

Thetail is so constructed as to have a double convex transverse shape and its surfaces are mer d ,into the surface of the body. The tei construction in its preferred form comprises aseries of pairs of laths 7) arranged transversely, and preferably in such manner that the said laths have their respective outer faces arranged on the inner sides of the lon tudinal members a, a pair of ion itudinal athsvcby means of which the en a of the transverse lathe b are connected together, a cross-bar d which forms therear endpt-thesaid frame-work and is connected at its ends to the said longitudinal lathe ,o, and also bracing upri hts such as those shownat N and b as wel as strengthenmg wires such as those shown at b.

I In the modified'tail construction shown in Figs. '6 and 7' two series of brackets 71 are hin ed 'to' the longitudinal members a, in sue manner that the may durinc, M ort be folded along t e faces of the or longitudinal lathe c and a cross her of sirmi a l lar to the preceding ones are used. The means for holding the said brackets in their preferabl normal position may consist of pins for temporarily securing the said brackets to the said longitudinal lathsxQ-alld also, ass

Fig. 7 shows the bracll ets 6 at the side of the tail disconnected from their corresponding lath c and in folded relation and at the 1 other side of the tail in.-exten ied .relationi sud operatively connected to thecorrespondizig lath c. in the construction of the covering a pair of pieces of canvas e may be used, being cut est te the desired sha e and secur'ed, for instance'bv sewing, wit those off their respective edges which, whenfthEerectin'g't-is tihish'ed, -must' be brought in correspondence with one of the lathe cjan'd which 'a'regpro vidcd on their otheredges-'with hoo'ksmr other means for'lacing, this being done in such manner that the wliole of the said parts 0 should 'forma cover or cese,owin for instance, to'theprovieion ofcorreep0n ing lacingv means at the desired "points of thehody, namely at its front-portion which, in its turn, is preferably covered. ,as shown at'c imFig. '1, so'thht'it can be, mounted in the 'sim lest'muinner-on'gthe body'and re moved from the top of the same.

For suspendin the rear part, a pair of bamboo rods Figs. 1 and 2) are used, which'a'rc bent and curved in a suitable menner, and lashed, for instance, to the bottom longitudiniiljtnembers a of the body so that they each form a kind of crescent at their rearendsand'are connected to each other, so that the wholejof the said parts, seen from the'end,'h1ive-the shape of an' X."
