My invention relates to building structures presenting relatively wide door-openings such as, and more particularly, aeroplane hangars, the door-openings in which are very 5 wide and high, and wherein it is desired that the doors be shifted into and out of closing position.

' The common practice in structures of this kind is to provide the door-opening within the confines of relatively wide door-jambs projecting inwardly from the front ends of the side walls of the building and to provide sectional doors which hang from tracks at the top of the door-openings and are shiftable from a position in which they close the dooropenings into a position in which they extend along the inside of the side-walls of the building, and vice versa.

The provision of the door-jambs presents a number of disadvantages, some of which are the added expense of constructing the building because of such jambs and the reduction in the capacity of the building due to the restricted door-opening resulting therefrom.

My primary object is to' provide a structure wherein the doors are movable from closed position into a position alongside of the side-walls of the building, and vice versa,

without requiring the use of doorjambs with the manifest advantages. v i I Referring to the accompanying draw- 1ngs:

Figure 1 is a plan sectional view, somewhat diagrammatic,-of the front end of an aeroplane-hangar constructed in accordance with my invention, the section being taken immediately above the door, one-half only of which is shown, and the roof-outlinebe- 40 ing shown by dotted lines.

Figure 2 is an enlarged view taken at the line 2-2 on Fig. 1 and viewed in the direction of the arrows, this view being an inside face view of a portion of the front ofthe building at the door-opening and one of the similar sets of door-sections employed.

Figure 3 is a plan sectional view of one of the front corners of the hangar, showing a portion of the door in closed position and' the track along which the door operates, the

section being taken at the line 3 on Fig. 4

and viewed in the direction of the arrow; and

Figure 4, an enlarged section taken at the line 4 on Fig. 3 and viewed in the direction of the arrow.

Referring to the particular illustrated embodiment of my invention, the front portions of the side-walls of an aeroplane-hangar are represented at 5, and the upper front wall of the hangar, which defines the upper boundary of the door-opening 6, is represented at 7, the extreme front edge-portions of the sidewalls 5 being preferably provided at their inner surfaces with relatively thin batten strips 8. Y

The door for the structure shown is formed of a plurality of edgewise opposing sections 9, there being twelve of these sections in this particular structure. The sections 9 are grouped into sets of three each, the sections of each group being hinged togetheras represented at 10 to permit the sections to swing inwardly relative to each other.

The door-sections 9 are supported on a.

track-structure to permit them to be moved from the position shown of the six sections at the left-hand side of Fig. 1 and as shown in Fig. 3 wherein the door-opening is closed, intoa position in which sixof the sections extend alongside of the front portions of one of the side-walls 5, and the other alongside the other side wall as shown of the six-sections at the right-hand side of Fig. 1 in whilch position the door-opening is uncov ere -The track-structure shown comp-rises a as represented at 13 of one end of the track in Fig. 3. The track structure also comprises tracks located at the inner sides of the side-walls 5 and closely adj acent thereto and parallel therewith which extend from the front wall 7 distances rearwardly thereof each greater two side-tracks, as shown at 16 of the track.

illustrated in Fig. 3, these switch track-sections being ivoted to the side-tracks 14 at therearen s of the aps therein, asillustrated at 17 of the trac in Fig. 3, and adapted to be swung into alinement, at their free ends, with either the rear ends of the tracks 14 at the front ends of the gaps 16 as shown by full lines of the track in Fig. 3, or with the rear ends of the curved ortions 12 of firack 11, as shown by dotte lines in this re.

n he tracks and switches are each of the type comprising a pair of spaced apart angleirons 18 and 19 connecte together in any suitable way, with spacers 20 interposed between their vertical flanges, the horizontal flanges of the angle-irons forming ways at which twin-wheeled hangers 21 swiveled at 22 to the door sections 9 and by which the door-sections 9 hang, are supported for movement along the tracks, the angle-irons of the stationary tracks being secured in position by lag-bolts 23 mounted to depend from timbers 24 secured to the building structure in a lane above the door-opening.

Tlib switch track sections 16 are supported in any desirable way from the structure above them and in practice means (not shown) positioned to be readily actuated by the operator, would preferably be provided, for shifting the switches alternately to the positions above referred to.

From the foregoing description it will be noted that, assuming the door is in closed position, in which the end ones of the hangers 21 extend at the extreme forward ends of the tracks 14 and the intermediate hangersengage the straight portion of the track 11, and it is desired that the door be 0 ened, the operator pushes the extreme end ones of the sections 9 toward the back of the buildin the end han ers 21, in this operation traveling rearwardly along the track 14 and drawing the two sections 9 connected with each thereof alon the track 11 toward therespective side-wafis 5, the hangers on these other door sections traveling along the curved portions 12 of track 11. After the end hangers have passed the switches 16 the operator throws these switches into alinement with the ends of the curved portions 12 of track 11 and all of these hangers of these two end groups of door-sections to extend along the portions of the tracks 14 to the rear of the gaps 15. The remaining two groups of door-sections may then be moved along the track 11 in opposite directions onto the tracks 14, respectively, at opposite sides of the building. If desired the switches may then be returned to a position in which the span the gaps 15 and the two groups of oer-sections at each side of the building moved forwardly along the tracks 14 to points closely adjacent the front of the building.

To close the door, the door-sections, if positioned as just stated, are pushed backwardly to pass wholly rearwardly beyond the switches 16, the switches then swung into alinement with the curved portions 12 of the tracks 11 and the door-sections moved, toward the center of the door-opening, along the tracks 11. When all but the last door hangers of the two end groups of door sections have passed the switches 16 the switches are swung back to fill the gaps 15 and these last hangers are then pushed forwardlyalong the front ends of tracks 14 to the position shown of the one hanger at the extreme lefthand side of Fig. 3.

From the foregoing it will be noted that by constructing a building in accordance with my invention the requirement for relatively wide door-jambs presenting the objections hereinbefore noted is avoided, while permitting of the withdrawal of the door sections to a position in the building wherein they are out of the way, thereby permitting practically the full capacity of the building to be utilized.

While I have illustrated and described a particular embodiment of my invention, I do not wish to be understood as intending to limit it thereto as the same may be variously modified and altered without departing from the spirit of my invention.

What I claim as new, and desire to secure by Letters Patent, is:
