To aZZ whom it may concem:

v Be it known that I, BRUNO KANNENBERG, a citizen of the German Republic, residing at Berlin Grunewald, 2 Franzensbaderstr., Germany, have invented4 certain new and useful Improvements inY Sheds for Airships (for which I have filed application in Germany May 30, 1919), of which the followisa specification.

The present invention relates to sheds for lair ships, and particularly to a rotary shed not provided with aoor. In its preferred form, the shed 'rests on a plurality of ring rails so that it may be'rotated. in any di-V rection necessary to permit the entrance or departure of the air ship. The invention contemplates especially 'a construction inV which the longitudinal supporting members of the shed, instead of being interconnected by the usual shed floor which is here lacking, are mounted on. one or more rigid ring members, which are of greater diameter than the width of the shed and are carried in shallow circular canals. The smaller ring also serves to support the shed against lateral wind thrusts or the like which are transf mitted through the ring to the foundation.

In the accompanying drawings- Figz 1 is a vertical longitudinal section through a shed, with two associated ring members; Y

Fig. 2 is a plan thereof;

Fig. 3 is a cross section through the shed, drawn to a larger scale and omitting the outerring;

Fig. 4 is a plan of portion of the inner ring;

Fig. 5 is a side element of one of the longitudinal supporting members of the shed;

F ig. 6 is a plan of the smaller ring; and VF ig. 7 is a section, on a larger scale,

' through this ring.

The present shed, in skeleton, comprises .two longitudinal supporting members 1, the

roof frame 2, and the two lower longitudinal tie elements 8 which connect together the frame members and reenforce it against wind stresses. The longitudinal supporting members 1 have upper and lower girders 3' and 4 respectively, which are united by i11- clined struts 5 and vertical struts 6. The inclined struts 5 are connected to the foot pieces of the vertical struts 6 by means of intermediate struts 7. The wind braces 8 comprise horizontal members 9, which conneet the foot pieces of the frame and are main frame.

' The longitudinal supporting members 1 are supported toward their opposite ends by -dependlng posts 13 on trucks 14, provided with four or more wheels, which run on cir- -cular tracks 15. Similarly toward their mid areas, the longitudinals 1 are provided with other depending posts 16 rest-ing on trucks 17, the wheels of which also run on a circular track 18. At the ends of the shed are sliding doorsf19, which reston a circular runway 20. In Fig. 2 the door at the lefthand end of the ligure is shown closed, while that at the right end is open.

The side walls of the shed are rigidly supported with relation to each other by two rigid flat rings 21 and 23, which are accommodated in two circular canals 22 and 24. The smaller inner ring 23 is connected to the side frames 1 of the shed at the points 30, 31, 32 and 33. In as Amuch as the rings lie below the surface of the ground, the connecting members must extend downward into'the canals for the rings. For this purpose special struts 25 and 26 (Fig. 5) are provided at the points of connection, from which the single connecting post 27 extends down into the canal. The lower end of the post, which at 3() is connected to the ring 23, is supported by the inclined struts 28 and 2 94 (Figs. 3 and 5) extending in planes at right angles to each other. In the same manner, connection is made between the longitudinals l and the inner ring 23 at 31, 32 and 33, and the outer ring 21 at 34, 35, 36 and 37.

The linner ring and outer ring are both formed by lattice work frames, and carry wheels 38 (Fig. 7) which run ontracks 39 laid on the bottoms of the canals 24. The frame of the inner ring 23 at the four Adiametrically opposite points 40, 41, 42 and 43 is connected by bars 44 with a link chain 45. Horizontal; rollers 46, mounted von this chain, bear against circular rail 48, which is embedded in the vertical side wall 49 of the the posts 44 are attached constitute half links 47. This arrangement prevents any cross strains at these points, and insures stresses only in the direction of the length of the chain. The wind stresses on the shed vcanal 24. The sections of the chain to which that the rollers on one half the chain are simultaneously placed under equal pressure. lf, for instance, as indicated by the arrow in Fig. 6, the Wind comes :from the left, the stresses are exerted at the points 41 and 43 on the roller chain, so that the half of the chainon the Windward side of the shed is placed under tension, While the half on the lee side is slack. ln this manner the wind pressure is distributed over a full half of the foundation ring,-a considerable span--A and a. full half of the chain takes the strain. By reason of this distribution of the stresses over the entire half of the ring foundation, the latter may be made relatively light.

The canals may be covered over by platforms carried by the rings and rotating with them. 'llhese platforms prevent the choking of the canals with dirt or snow, and thus keep the structure in operative condition.

"Where the shed is relatively short, a single ring sufiices to aliord the necessary rig-` idity to the structure. lf the shed is of greater length, more than two rings may be used if necessary or advisable.

l claim as my invention-- l. A rotary shed for air ships, comprisinga pair of horizontal side iframes, and ring means having a diameter at least equal to the width of the shed, and to which the side "frames of the latter are connected, said ring means constituting tie means by which the'side frames of the shed are united, substantially as and for the purpose set-forth.

2. A rotary shed for air ships, comprising a pair of horizontal side :trames and a plurality ofconcentric rings, certain of which are of reater diameter than thewidth of the she and to which the sides of the latter are connected, said rings constituting the tie means by which the side frames of the shed are united, substantially as and tor the purpose set forth.

3. Arotary shed for air ships, comprising a pair of horizontal side frames, and subsurface ring meanshaving a diameter at Q I y 1,426,197

'means by which the side frames of the shed.

are united, together with a platform carried by the ring means at ground level, suhstantially as and for the purpose set forth.

5,. A rotary shed for 4air ships comprising 4a pair of horizontal side frames, and a ring of greater diameter than the width of the shed, and to which the sides of the latter are connected for the purpose speciied, 'together with a roller chain operatively associated with said ring and an abutment against which said chain bears to take up lateral stresses on the ring.

6. A rotary shed 'for air ships comprising a pair of horizontal side frames, and a ring of greater diameter than the width et the shed, a-nd to which the sides of the latter are connected for the purpose specified, in combination with a sub-surface circular canal in which said ring is accommodated, together with a roller chain loca-ted in said canal and bearing against a side wall thereof, and means connecting said chain and ring together.

7. A rotary shed for air ships comprising a pair of horizontal side frames, and a ring of greater diameter than the Width of the shed, and to which the sides of the latter are connected for the lpurpose speciiied, together with a link roller chain operatively associated with said ring, and a link connection between the chain and ring for the purpose described.

In testimony whereof ll have vsigned my name to this specification.
