doors of comparatively large dimensions.

and massive weight and to mount the several doors on separate tracks, the tracks extending across the doorway and being positioned one behind the other. This practice is open to numerous objections and disadvantages, among which may be mentioned the relatively large amount of space occupied by the tracks and which space, as far as housing of the aircraft is concerned, is practically wasted. In some cases, the distance between the front and the rear tracks is as great as three feet. The laying of a plurality of tracks and the installation of corresponding overhead tracks entail relatively large expense for the materials employed and also for the construction work.

The present invention has as its object the provision of an improved construction wherein the number of tracks within the hangar doorway is reduced to a minimum, and the doors may be brought into position one behind the other at one side of the hangar without increasing the width of the doorway or the extent to which the doors,

when in open position, extend beyond the side of the hangar. To these ends, there is provided, in accordance with the present invention, a single supporting track within the doorway adapted to hold a number of doors end to end, and at one end of the supporting track is a carrier adapted to be moved to successive positions so, as to receive the doors in a relation one behind the other.

. My improved construction is a very simple one wherein the doors maybe very easily and conveniently moved to shut or open only so. much of the latter being illustrated positions as desired, and the space occupied by the doors within the hangar opening is relatively small. My, improved .arrangement may be installed at a lesser cost than the arrangements now generally employed.

4 Other objects will be in part obvious, and

in partpointed out more in detail hereinafter. 7 y

. The invention accordingly consists in the features of construction, combination of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth and the s copeof the application of which will be indicated in the appended claims.

In the accompanying drawings, the improvements of the present invention are shown more or less digrammatically as being incorporated in an aircraft hangar,

as'is necessary for a complete understanding of the invention. g

In these drawings, Fig. 1 is a front elevationa-l view of one end of the hangar, and illustrates two doors as being supported by the track in the hangar doorway, and one door as having been moved to complete open position;

Fig. 2 is an elevational view looking at one a side of the truck or carriage onto which three of the doors have been slid; and

Fig. 3'is a top plan view of what is shown in Fi 2.

Referring to the drawings in detail, 9 designates one side wall of the hangar; 10, the roof; and 11, the concrete floor thereof. The numerals 12, 18, and 14 designate the several doors mounted on rollers or wheels 15 of anysuitable number. These rollers are more or less diagrammatically illustrated as the construction thereof forms no part of the present invention. Rollers of this type are old and well known in the art. Each door may have at its top edge suitable horizontally disposed rollers 16. i

Embedded in the floor 11 of the hangar and in the doorway thereof is a supporting track 20, which may be of the usualI-beam I Positioned at the top of the doorway and in vertical alignment with the supporting track 20 is an overhead track 21 which may be of the usual box type. This track is adapted to receive the overhead rollers 16 in such manner that the rollers engage the vertical walls of the track at diametrically opposite points.

To one side of the hangar is a concrete foundation 25, the upper surface of which is below the surface of the floor 11, and can bedded in this foundation are two spaced apart parallel tracks 26 which are disposed at an angle to the track 20. In the present instance, the tracks 26 are at right angles to" the track 20, and they run rearwardlyv along the side of the hangar. t the forward and rear ends of the tracks 26 are suitable stops or buifers 27. Mounted upon the tracks 26 is a truck or carriage of any suitable construction. By preference, the frame of the truck is of skeleton frame, the framememhers being designated by the numerals 28. The truck, at opposite sides, has pairs of wheels 29, respectively riding on the tracks 26. Mounted on and extending transversely of the truck is a plurality of supporting tracks 30 of a construction identical to the track 20 and located at the same height as 30, and of like construction as the overhead track 21. These tracks 31 are so positioned that they may be brought successively into exact alignment with the overhead track 21.

Any suitable means may be employed for moving the truck to its several positions so as to receive and deliver the doors. For example, one of the bottom side sills of the truck may have a rack 35 with which meshes a pinion 36 fixed to a shaft 37 mounted in suitable fixed bearings 38. This shaft may extend through the side wall 9 of the hangar. On the other end of the shaft 37 is a suitable ratchet wheel 39 with which cooperates a pawl 40 operatively associated with a lever 41. By moving the lever 41 back and forth, the shaft 37 is turned inone direction or the other, as the case may be, so as to move thetruck. There may be provided, at the top of the truck and above the overhead tracks 31, a suitable shroud or canopy 42 for protecting the tracks against rain and snow. This canopy is shown in Fig. 2 but is omitted from the otherfigures. V f

The operation of my improved arrangement will be clear from the foregoing description taken in connection with the accompanying drawings. t will be observed that, when the hangar is closed, all of the doors are positioned on the track 20 in end to end relation. When it is desired to open the hangar, the endmost door is slid onto one of the tracks 30 of the truck; then the truck is moved to bring another track 30 into alignment with the track 20, and the second door is moved onto the truck, and so on until all of the doors have been moved onto the truck.

To close the hangar door, the operation is reversed.

As in It is also to be understood that the language used in the'following claims is in tended to cover all of the generic and specific features ofthe invention herein described and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.
