COLLAPSIBLE ROOFED COT.

Specification of Letters Patent.

Patented Apr. 12, 1921.

Application filed December 4, 1916. Serial N 0. 134,854.

To all whom it may concern:

Be it known that I, ISAAC S. PURGELL, a citizen of the United States, residing at Oak Park, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Collapsible Roofed Cots, and I do hereby declare the following to be a full, clear, and exact description of the invention such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to roofs and canopies for use over cots or other forms of beds, and its general objects include the providing of a readily portable, easily erected and partially separable frame for firmly supporting a tent or canopy over a cot or the like; also, the providing of simple and effective means for securing various portions of the tent against movement with respect to the frame or cot, and means for readily converting the tentinto a canopy or sun shade exposing one side-of the cot. Further objects are to provide fastening means for securing certain portions of the tent to each other or to the frame and the cot when the tent forms a complete housing for the cot, and to use the same fastening means for also holding some of the tent portions in operative position when the tent is converted into a sun shade. Furthermore, my invention aims to provide a tent-supporting frame over which the tent may easily be spread before the frame is aflixed to the cot or bed thus enabling the frame and tent to be jointly superposed upon the cot, also, to provide means for permitting a tightening of the canvas or other bed bottom without interfering with the speedy erection of the tent or canopy, and to provide simple means for preventing an accic ental detachment of the tent-supporting frame from the cot. Still other objects will appear from the following specification and from the accompanying drawings, in which drawings- Figure 1 is a perspective view of a folding cot equipped with atent-support and a partly opened tent embodying my invent on.

Fig. 2 is an enlarged fragmentary view of one of the members comprising the tentsupport.

Fig. 3 is an enlarged view showingthe juncture between the two parts of the ridge rail.

Fig. 4 is an enlarged fragmentary section along the line 41 of Fig. 2.

Fig. 5 is a cross-section taken along the hne 55 of Fig. 3.

Fig. 6 is a perspective view of the cot with the tent-supporting frame but with the canvas bed-bottom omitted.

Fig. 7 is an end View showing the tent in position for completely sheltering the cot.

Fig. 8 is an enlarged fragmentary View showing the method of securing a side of the tent to one of the side rails.

Fig. 9 is a perspective view showing another method of opening one side of the tent.

Fig. 10 is a transverse section along the line l0l0 of Fig. 9.

Fig. 11 is a transverse section along the line 11--11 of Fig. 1.

Fig. 12 is an enlarged perspective view of one of the corners of the cot.

Fig. 13 is an enlarged fragmentary view of one of the tent-supporting members partially folded for stora e.

While my invention in most of its aspects relates to tents and canopies and means of supporting both with relation to any given base, it is particularly applicable to uses in which this base is formed by the frame of a cot or bed, being in many ways an improvement over the constructions shown in my copending application filed Oct. 7 1916, as Serial No. 124215. I have therefore illustrated it as used in connection with a folding cot suitable for outdoor use andv half-rotations of one of the end rails as described in my copending application.

Near each corner of the rectangular frame constituted by these rails I provide an aperture or socket opening upwardly, as for example a slot in the tip portion of each end rail 2, thereby affording seats for the tips of legs 5 forming parts of a tent-supporting frame. The latter frame is desirably made of angle steel and preferably consists of two separable portions each comprising a ridge ofthe legs 5, which brace may be hooked over apin on a rail portion 6xas shownin Fig. 2, thereby maintaining this ridge rail portion rigid with respect to the common plane of the legs 5. By using such a brace in combination with the previously described slip oint betweenthe sections of the ridge rail, I provide a two-part frame which may readily be set up on the ground and over which the tent may he slipped while the frame'is in this low and accessible position, after which the frame may be raised over the'cot and set into its normal position with the tips of its legs engaging the socket formations on the bed-bottom frame and with the flaps of the tent hanging down below the latter frame.

To prevent an accidental detaching of the tent-supporting frame from the bed-bottom frame, I preferably equip the tent with means engaging the latter frame, thereby simultaneously holding both the tent and the frame for the latter inoperative position. For example, hooks 9 may be swiveled to the inner surface of the tent side 10 and maybe hooked under the side rails 1 of the cot, as shown in Figs. 1 and 8, and if the tent i s'provided with the auxiliary draftexcluding flaps 11 described in my said copending application, these hooks are preferably disposed betweenthe tent sides and the auxiliary flaps as shown in Fig. 8. At

each end of the tent I also desirably provide similar hooks secured to the material of the tent andengaging some portion of the bed-bottom frame near the corner of the latter, as shown (for example) in dotted lines in Fig. 12. By swiveling the first named hooks, I attain another purpose, as

these hooks may be swung around and hooked over the top of the tent when one side of the latter is folded upon itself as shown in Figs. 9 and 10, thereby holding this side portion in effective position for enabling it to act as a sun shade or canopy.

The end flaps of the tent are suitably shaped and overlapped and provided'with may bethrown back over the ridge of the tent as shown in section in Fig. 11, whereupon a portion of the raised flap may be lapped over the adjacent leg 5 of the tentsupporting frame and fastened in place by snapping one of the fastening elements on this flap to a normally higher element 'on the other flap at the same end of the tent, as shown in Fig. 1.

To allowforthe'tensioning of the canvas bed-bottom, I preferably provide both the upper and lower faces of the rotatable end rails with slots ofsockets for receiving the feet of'the legs 5, which feet aredesirably made by extending one web of the angle beyond the end of the other. However, while I have shown this particular form of foot construction and have described a particular form of slip joint for the juncture of the ridge rail sections 6, I do'not wish to be limited to these or details ofthe construction and arrangement here described, it being obvious that the same might be modified in many ways without departing from the spirit of my invention. For example, instead of hooking all of the hooks 9 over the top of the tent when the latter is converted into a side-open tent as in Fig. 9 each end hook may be snapped into a ring 14 secured to the ridge portion of thetent and otherwise serving as a handle for raising the tent over or off the frame which supports it. So also, it will be obvious that after loosening the hooks 9, or the fasteners 12 and 18, the tent may easily be taken off its frame and rolled or folded and that it may readily be used as a wrapper for. the previously folded cot and tent-supporting. frame, thereby permitting the entire structure to be stored or carried in compact form. Or, if the tent is to be used by campers, the cot portions, tent-frame portions and the tent proper may all be carried by different persons, so as to distribute the load.

I claim as my invention: 1. The combination with a bed-bottom frame having upwardly open sockets, of a tent-support including an angle-steel ridge member and frame-members supporting the ridge member, each frame-member comprising a pair of angle-steel bars pivoted respectively to the two webs of the ridge member at the same end of the latter, and each of these bars having at its free endone web thereof projecting beyond the other web to afford a projecting tip entering one of the said sockets, the end of the said other web affording a shoulder to limit the entry of the tip into the socket. Y

2. A tent-supporting structure as per claim 1, inwhich the ridge member comprises two angle bars having relative overlapping ends, and a short member secured to one ofthe bars and having a portion thereof spaced from the last named bar to legs being pivoted respectively to the two 10 permit the slidable insertion of the end of Webs of the angle steel ridge member and the companion bar therebetween. adapted to fold about their said pivotal con- 3.
