The inner ends 0 the rear spare ll of the upper right and left wings 1, 2 hinged to the ends of the rear upper cente spar 10 of the struts fi and 6, while the are 11 of the loweigright and left winge ringed to the rear lpwer sper 10 of the etrute 5 and 6. Any suitable construction of hinges ma be employed for this purpose; the form illuo trated primarily consists, as shown at Fig. 5 of two plates firmly bolted to the upper and lower surfaces of the spars 1.1 and connected by hinge pins 12 to extension members of the rear center 10, l@*, and through the heads of the pins 12 there are holes, to which in one case are attached the back main flying wires 13, and in the other the main landing wires 14, see Fig. 5, It will thus be observed that the points, where the rear spars 11 of the upper and lower portions of the wings are hinged to the upper and lower center spars 10 and 10*, is such that when the wings 1, 2 are turned about the hinges described into the fiyiu position indicated by the dotted lines at ig. 2, the inner ends of the upper hinged wings will conjoin the ends of the center fixed plane 8, while the inner ends of the lower hinged wings will abut against the lower part of the sides of the fuselage 7 Since in a folding sU-ucture shch as now described it is obvious that the weight of the hinged wings is liable to cause the peel tion of the same to very relatively to the central stationary framework when brought from the folded to the expanded position and relatively also to the required position of rest when brought from the expanded to the folded position, it is highly necessary not only to provide means for connecting the inner ends of the front spars of the wingsto the stationary framework when brought to the expanded position, but it is also highly necessary to provide guiding means to facilitate the uiding of the said front spars into proper a inement. Also it is equally necessary that when folded the wings should be supported and secured in such required position, and also that they should be guided and directed to such position of fixture. To these ends the invention provides follows. The inner ends of the front upper spars l5 and the inner ends of the front lower spars 16 of the hinged wings are fitted with projecting tapered pins 1? as shown at Fig. 4, which tapered pins are adapted to enter the ends of the tubular front upper center spar 9 and the tubular front lower center spar 9 of the central stationery framework, which spars 9 and 9 are carried by the vertical struts 3 and 4. The upper pins 17 fit firmly nuance Zl'ltO the tubular front upper center spar 9" and are held in position y screw bolts such as 18, Fi 4, passed through the tube and through t 1e pins 17. The pins 17 are pointed to facilitate their entrance into the tubular ends of the spars 9 and 9, and downwardly curved guides are provided onjthe with and against the frame or fuselage they do, not overlelp each other but are brought into connection with the frame and so firmly held imposition. Means are illustrated, particularly at Figs. 1 and 7 to 9, by which thifl is accomplished, such means consisting-of forked sup orts .20 fixed to the fuselage 7, below which and also attached. to the fuselage is a. guiding fork 21, F i 6 and 9, the extremities of which are inclined. Fixed to the rear struts of the 'main plane are two rollers 23, Fig. 9, which when the planes are folded. mount the guiding forks 21, while the struts 22 enter between the forks of the supports 20 and at this point see Fig. 8, the struts are fitted with flanged collars 24. The rear ortions of the mam planes, when so folde undue strain upon the hinges of the spars 11 described at Fig. 5. Thus when the folding plenes are brought into the flying position, the connections of the upper and lower front spurs are guided into engagement as de' scribed wit reference to Fig. 4, and similarly when the wings are brought into their back, are thus supported and ,relieve folding position the rear portions of the I wings are again guided into their supports 1 as at Figs. 7 to 9.

Wires or cables are connected to the win for the purpose of moving them from their folded position to their flying position, and vice versa, and such wires are led around suitable guiding pulleys or fair leads to winches. These winches are or may be provided with any well, known ratchet and pawl devices and with brakes, for the purpose -of prevent' g the movement of the wings except n substantial force is applied to operzXe the said winches.

In the condruction illustrated in the drawings, at l 'igs l and 2, two wire cables 25 are provided, oneend of each cable be- ,be operated by the pilot or his assistant.

In the drawings a second which 30, Fig. l, is provided for drawing the planes rearward when being folded, and to this winch 3C cables 31 are attached, respectively passing around pulleys underneath the fuselage,

'and so res'ectivelV to the rear arts of the folding wings to which the ends of the cables 31mm connected, indicated et 32, 2.

Obviously-to bring the folding wings from the fio'sitionat Fig. 2 into the position for flight, the cables 25 must be wound up on the drums of the winch :29, while the cables 31 must be simultaneously unwound from the drums of the winch'30.

When planes having a largechord are used and it is required to fold them in this manner, it is preferable to construct the remwportion of the wings so that they hinge"(lolwn in flaps immediately behind the i-ea-r spar, so that when the planes are folded back, they can be brought closer togather thanthey otherwise would be. The total breadthacross' the two planes would, when folded under those conditions, be somewhat less than, double the chord of the plane. 1

l The outer portion of the wings together with the struts and stays connecting the upper and lower wings therefore swing on their hinges in the manner of gates and ha-re an open posit-ion and a closed position. They are never adjusted inflight tween these two positions, simply passing from one osition' to the other according to which 0 the two positions is deeired.
