AEROPLANE HANGAR Filed April 9. 1929 Patented oet. 2s, 1930 PATENT. OFFICE WILLIAM R. W.;AT1, 0F WILMINGTON DELAWARE AEROELANE HANGAR Application. led April 9,

The objectl ofthis invention is to provide a suitable storage space or hangar for heavierthan-air craft.Y In the type of hangar used atthe present time, there is a considerable amount of waste space when'individua'l stalls lare used due principally to the peculiar shape of modern aeroplanes. When aeroplanes are v stored in large hangars, it is extremely dilicult to dispose them so as to eeonomize in space. When it is desired to remove a plane from this4 type of han gar, it is often necessary to move all of the stored units to finally reach the particular plane desired. It is also /f obvious that, with a large hangar, inthe winter time, there is a great heat loss dueto thefact that the doors, which in most cases constitute one side of the "building, must be opened, thereby exposing the interior to the outside air. It is also a fact that in case of a fire, in such a hangar, the possibility of localizing the flames is remote and there is little hope of saving all of the planes stored therein.

There has long been a demand on the part of`aireraftoperators and pilots for a type of hangar, which will'provide at a reasonable cost, individual stalls each adapted to contain an aeroplane in such position that it couldbe readily removed and, at the same time, afford the advantage of permitting work on the plane without difficulty or cramping. yIn recognition of this need or a new type of hangar, the applicant sets forth in the following views a novel and improved design, ofwhich Fig, 1 is a sectional plan view taken lon the line 1-1, Fig. 2, diagrammati'cally illustrating a preferred type of hangar;

Fig. 2 -is a sectional View taken along the line 2f-2, Fig. 1, showing in some detail the 'arrangement of the doors, windows and roof of the hangar; and Fig. 3 is a diagrammatic View illustrating Y i a modified arrangement of the stalls in the hangar.

Referring to Fig. 1, it lwill be noted that the individual stalls are represented by 1.

The hangaris octagonal in shape, each stall 1V having a Hoor plan substantially in the 5'0 form of an isosce'les trapezoid. At the oppoy ing above the tops of the stalls',

site sides of the hangar are assageways 4 leading to a central .space 5 er repair material, shops, offices, etc. The stalls 1, as shown in the preferred arrangement, consist of the side walls 6, a front entrance 7 hav- 55 l ing suitable doors 8, which are preferably ofV the folding type, opening to theflying field, and a back entrance 9 closed by the doors 10 and opening to the central repair and oilice space 5. An aeroplane 11 is shown dia ram- 60 inaticallyi'n one of the stalls with bot the front and rear doors closed and the 'aeroplane 12 is shown either leaving or entering one ofthe stalls. 13 represents a fuselage of a plane being taken from one of the stalls into the space Where any'extensive repairs that may be desired may be performed.`

Fig. 2 shows particularly some'of the details of construction. It may be noted that in order to secure ample light in the stalls when the doors are closed, a shouldered roof 14 surmounts the stalls.v This roof allows the windows l5 to be placed as shown in the break in the roof, giving light and, when necessai-y, ventilation for the individual stalls. As mentioned heretofore, the doors 8, which4 are preferably of the folding type, open to the iiying field. The doors 10 open into the central-space 5 and themotor, Wings, fuselage 'or any other part ofthe' plane may be taken so l through this back entrance 9 into the space 5 for rep/ai rs. 'lhe centralspace 5 is sultably ventilated and illuminated by thel windows 16 which are placed in the walls'17 projectand supportingthe central part 18 of the roof 14.

It is-obvious, therefore, that this particular arrangement makes a A' very desirable hangaristructure.

As' shown in Fig. 3, the arran stalls may be modified so as to ispense with the central space 5. In this plan, the stalls are builtin a straight line side by side, alternately facing front and back. A plane landementof the ingl on the particular field-where this hangar is located would taxi up to it and the pilot would be informed as t'o the particular stall which his plane is to occupy. He would then move his s iip to a convenient position in front of this stall with the tail of the planepointed 1-00 muy toward the entrance in a position similar to thatI of plane 12. The plane could now very easily be backed into the stall and housed for a time, or repaired as required.

` In the hangar as shown in Figure 1, for instance, if it were necessaryto weld a section of the fuselage, the wings could be detached and the fuselage removed from the stall through the rear doorway into the repair space 5, where everything'could be done. In inclement weather, all of' the operations necessary could illus be performed inside. AIn its preferred form, the hangar is constructed entirelyof fire-resistant material including the doors 8 and 10. It, therefore, may be seen that'in case of fire in any particular stall or in the center/of the repair section, the fireresistant construction of the entire structure, including the doors, would effectively prevent the spreading of the flames.

The roof 14 slopes downward somewhat to the shoulder having the windows 15, and the Walls 17 with the windows 16 are in substantial alignment with the rear backs of the stalls l. Between the windows 15 and 16 is a circular depression 19. The center 18 of the roof may be slightly arched. Suitable means may of course be provided to drain the section 19.

I claim: l

1. A hangar having a plurality of radiating stalls, reach with a floor plan of substantially trapezoidal form, a front entrance.

opening to the exterior of the hangar and a back entrance opening into a space at the center of the hangar, two side walls set at an angle to conform to the general outline of an aeroplane, and a roof for the hangar the central space being of a vsize to receive the fuselage of the aeroplane, the rear entrances permitting removal of the fuselage of an aero plane disposed in any of said stallsto said central space.

2. An aeroplane hangar having a stall with a floor plan of substantially trapezoidal form, a long front and a short back wall, two side walls diagonally arranged relative to said front and back walls, a roof downwardly offset intermediate the frontand back walls with the internal shoulder produced by offsetting facing the front wall, and windows 1n the shouldered part` of said roof and windows in said shoulder.

3.y A hangar comprising a pluralityof radiating stalls each with a floor plan lofsubstantrapezoidal form, said stalls being arranged abouta central roofed space, each stall having a roof downwardly offset between its inner and outer ends, the inner ends of the roof sections bein lower than the roof section of the eentraspace whereby a substantially annular depression is formed, the inner and outer walls of said depression having windows, said central space being of a size to receive the fuselage of a plane, said stalls tween its inner and outer ends, the. inner ends' of the roof sections being lower than the roof section of the central space whereby a substantially annular depression is formed, the inner and outer walls of said depression having windows, vsaid central space being of a size to receive the fuselage of a plane, said stalls having each a door in its inner wall permittingfremoval of the fuselage from the stall to said central space, and means affording access to said central space independently of passage through any of said stalls.-
