(01. 135-1) The ‘present ‘invention relates to a tower enclo sure adapted for drying parachutes singly or en masse ‘having for its objects generally stated, pro viding a tower enclosure having a number of rope pulleys at its top suitably spaced and means whereby the .top of the parachutes may be at tached to one end of a rope and pulled to the top of the tower for drying. 2 Fig. 9 is a sectional view through a fraction of one side of the bottom section when collapsed. Fig. 10 is a diagrammatic drawing of my tower building and a fraction of a shelter building as shown in Figure 1. Fig. -11 is a detail view showing the latch means for holding the parts shown in Fig. 9 in their extended position. As thus illustrated it will be seen that my im ‘Generally stated‘ the :present invention has the following important characteristics: can be. man u‘factured at 'low cost, is light, storm and weather proof, collapsable in two or more sections which can v‘be enclosed in bags for stacking, storageor sections, the lower section being designated in its entirety by reference character A and the upper section being designated in its entirety by ref shipping, easily erected" or assembled and as. eas erence character B. proved tower building comprises preferably two ' ' ily disassembled and shipped either .by truck, My tower building comprises a number of cir trailer or airplane. ‘ ' cular rings which are preferably laminated wood. An ‘object of vmy invention is to provide means The bottom ring of the bottom section is desig for escape of air near the top of the tower and nated in its entirety by reference character C. means for admitting preferably” heated air at its The other rings are designated in their entireties bottom to thereby provide natural circulation of 20 by reference characters D, E, F and G. The air around the parachutes thus to expedite the floor assembly of my improved tower is designated drying Process. ’ in its entirety by reference character vH. 'The aboveenumerated objects and character _ Floor H comprises spaced slats l0 and spaced istics provide a device particularly suitable, for slats l l , which are at right angles to slats l0 and quick transportation and emergency air ‘ corps 25 preferably considerably further apart than mem service. To these and other usefulends my invention consists of parts, combination of parts or their equivalents and method of manufacture, knock~ bers l0. Members l2 act to suitably secure the ends of certain members i fl together. Member C has secured thereto in spaced rela tion a number of spaced stake rings I3 with ing down, erecting and disassembling as described 30 which the building may be anchored to the ground and claimed and shown in the accompanying by means of suitable stakes. I provide a fabric drawings in which: ' member II! which on its inner edge is secured to Fig. 1 is an elevational view of my complete member 0, (see Figures 1 and 3). Section A of tower showing a fraction of another building and my improved tower comprises preferably 3 rings having a canopy passageway thereto. ' .35 C, D and E.

Ring C is adapted to rest on the outer periphery .Fig. 4 is a bottom View .of ring G and all of of member H, and may be secured thereto in any the parts attached to the ring and. above the suitable manner. ring. . I secure a blanket or fabric covering l 8 to mem . Fig. .5 is‘ a .top view ‘of the bottom ring of the 45 bers C, D and E (see Figures 1 and 8). Member I8 is secured to the rings so it is stretched taut bottom section of my improved tower. A por tion‘of the collapsable ribs is shown and in sec tion and illustrating four stake rings with which the tower may be secured to the ground. Fig. 6 is a bottom view of the top section when collapsed for packing or transportation. when the ribs are extended as shown in Figures 1 and 3. It will be ,seen that when the ribs are folded, as in Figure 9, blanket [8 will fold inward as shown in this ?gure and in Figure 6, and when thus collapsed and folded the units may be placed in a sack I 9 and the sack laced as shown in Figure 2 suitable for storing or shipping. The member Fig. 7 illustrates the preferred form of a ?oor when viewed from the bottom. . . Fig.8‘ is .a detail of fractional sections through one side of my improved tower."

Blanket I8 is provided preferably with two 2,406,724 3 4 preferably ?rst secured to member I-I then the upper half of member A may be extended after openings 20, one on each side, through which warmed air may be forced in order to expedite the which member B may be extended and placed on drying process. The air passes upwardly through the top of member A, then the upper portion of the building may be lifted so the low half of mem units A and B and escapes through an annular opening in the top of unit B as will hereinafter her A may be extended. Sometime during this erecting operation member l4 may be moved out ings 2%! by means of an air heating core and fan. of the way or slitted and stakes ?tted into rings An opening 2| for attendants (see Figure 10) 13 and driven into the ground so the bottom of is provided by extending portions of member l8 the building is suitably anchored to the ground. 10 outwardly as at 22 so as to form a canopy en It will be understood that my building may be trance way, I prefer to position my tower close to appear, the air being moved preferably to open ' erected or disassembled in any manner suitable the end of a shelter building K and adjacent the ' door therein, the end of canopy 22 being detach-3 '; for the local conditions. The above described erecting method being the preferred form. ably secured to the frame of the door in member, K. Shelter building K is shown and described in 15 After ribs l5 or 23 are extended they are held collapsing by means of straps 50 (see Fig a copending application, Serial No. 464,314, ?led _ ' from ure 11) which .are hinged as at 5| on the upper November 2, 1942, maturing into Patent No. ribs and having an opening 52 adapted to en 2,363,916, November 28, 1944. Member B comprises rings F and G having “ spaced pairs of ribs 23, theirinner ends ‘being gage bolt 53 in the lower ribs and having a 20 thumb nut 54 by which the strap is made taut hinged together as at 24 and the outer ends being hinged to rings F and G- as at 25—25. A blanket 26 is secured to rings F and G as illustrated in Figure 8 and having a length so it will be stretched when the ribs are extended. " Under some conditions the circulating air will not need to be heated and it may be 'moved by natural draft and still dry the parachutes taut with members 23 extended. An outer ring 25 The building is preferably the right diameter 21 is secured to ring G by means of spaced blocks so eight parachutes will hang free in a circle and successfully. 28 so as to provide an annular opening 29 from which the circulating air may escape. A spider frame is secured to member G and comprises a center piece 30 and a number of ribs 3!. I pro vide preferably a ring 32 which is secured to ‘ members 3| and has slidably mounted thereon a ' ' form a circle large enough so a parachute may be suspended in the'center from member 38.
