FOLDIN G COT.

SPECIFICATION forming part of Letters Patent No. 729,486, dated may 26, 1903.

A Application filed (lune 19,1902.

To all whom it may concern:

'Be it known that I, ABRAHAM OAN'roB, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Folding Cots; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying draw ings, and to the letters of reference marked thereon, which form-a part of this specification.

This invention relates to improvements in sleeping-cots; and'the invention refers more specifically to an improved construction designed to permit the cot to be folded in a small compass, and thereby enable the same while being stored or transported to occupy a relatively small space.

The invention consists in the matters hereinafter set forth, and more particularly pointed out in the appended claims.

In the drawings, Figure l is a perspective view of a cot made in accordance with my invention. Fig. 2-is a perspective view of the cot when partially'folded or collapsed. Fig. 3 is side elevation of the cot-frame when fully folded. Fig. 4 is a vertical section taken on line 4 4 of Fig. 2. Fig. 5 is an enlarged elevation of the upper end of the foldedcot. Fig. 6 is aninside view of one, of

the longitudinal rails, showing the manner of fixing the canvas support to the rails. Fig. 7 is a detail plan view of the intermediate portion of one of the side rails. Fig. 8 is a side elevation thereof. Fig. 9 is a perspective view of the head end of a cot, showing a modification.

As shown in the drawings, A A designate the side rails of the cot,and B the canvas support thereof, which is stretched between said side rails and attached at its margins thereto in a manner hereinafter to be described. The frame of the cot consists, in addition to said side rails, of cross supporting-bars C O at the head'and'foot ends,respectively, of the cot, and intermediate cross supporting-bars C supporting-bars O O O are pivotally connected with each other between their ends, and the end supporting-bars O O arehinged'at their upper ends to the ends 'of the side rails A in a manner to swing toward and from the cen Said Serial No. 112,268. (No model.)

ter of the cot. Said end cross-bars C C are braced by means of brace-rods D D,wl1ich are pivotally connected at their outer ends with the lower ends of the bars 0 C atthe head and foot of the cot and are provided at their inner ends with hooks cl, adapted to engage eyes a in the side rails in the manner shown in Fig. 1. E designates an inclined head or pillow support, which is made of canvas or like flexible material. Said pillow-support is attached at the inner margin thereof transversely across and to the canvas support B by means of stitching orthelike and is attached along its outer margin toa transverse strand or cord 6, which is secured at its opposite ends to vertical rods E E, connected with the head supporting-bars. As herein shown, said-bars E E are hinged at their lower ends to the lower ends of the supporting-bars C and pass upwardly loosely through eyes 0. 0, attached to the upper ends of the head supporting-bars O in the manner shown in Fig. 4, each rod E being attached at its lower end to the lower endof one of the cross supporting-bars and engaging at its other end the eye 0, which is attached to the upper end of the other bar 0.

Instead of employing the flexible pillowrests E, I may employ'a frame F, secured directly to the vertical rods E, in themanner shown in Fig. 9. Said frame is made of lazy- -tong construction, so as to fold closely together when the bed is folded in the manner shown in Fig. 2.

The side rails A consist, as shown in Figs. 3, 5, 7, and 8, of an intermediate stationary section A- and end sections A A which are hinged at their inner ends to said stationary sections in a manner to swing toward and from the center of the cot. Said side rails are made of angle-bars and the supporting-bars O to C are attached to the webs 0L thereof. The intermediate;supporting-bars C are rigidly attached to the webs a of the intermediate stationary sections of the rails by means of rivets c Said webs of the rails when the cot is folded occupy vertical positions, but when the cot is in its open position,

as shown in Fig. 1, are inclined downwardly and inwardly to correspond with the direction of inclination of said supports 0 The flanges a of said rails are at the upper sides swinging sections A are cut away, so as toform shoulders of, which abut against shoulders formed by the ends a of the flanges of the intermediate sections, whereby when said outer sections are swung or folded upwardly -into alinement with the intermediate section a knuckle-joint is formed between said intermediate and outer sections, which holds said sections in line when downward pressure is exerted thereon.

The canvas support 13 is folded at its side margins over the side rails and is provided with apertured straps Z), as shown in Figs. 5 and (3, which are adapted to pass inside the web of said rails and to be engaged with buttons or hooks a extending inwardly therefrom. If desired, the buttonholes may be formed in the margins of the canvas support, thereby omitting the strap 1). Inasmuch as the attachment of the intermediate supporting-bars (I with the intermediate sections A of the side rails prevents the margin of the canvas support being folded downwardly at these places inside of the webs of said sections, said websare shown as provided on their outer surfaces with hooks or buttons a, which engage buttonholes formed in lateral flaps B of the canvas support.

\Vhen thecot is to be folded, the first operation of folding consists of detaching the bracerods D and thereafter lifting the cot by the side rails A near the central parts thereof and at the same time forcing said rails together. This operation folds the cot flat, in the manner shown in the left-hand side of Fig. 2, with the supporting-bars C C C substantially parallel and side by side. The next operation of folding the cot consists of swinging the brace-rods D upwardly into vertical position against the supporting-bars O O and turning the end supporting-bars (J C and brace-rods D inwardly toward the center of the cot, in the manner shown at the righthand side of Fig. 2, until said supportingbars are thrown up parallel with the side rails. Thereafter said side rails and supportingbars are swung inwardly toward the intermediate supporting-bars G the supportingbars G O occupying positions between said intermediate supporting-bars and the end sections of said side rails, as most clearly shown in Figs. 3 and 5.

The vertical bars E, by which the pillowsupport is sustained, maintain their vertical and parallel relation, the eyes or loops 0 of the supporting-bars sliding upwardly and downwardly on said rods as the supportingbars are opened or closed.

It will be seen from the foregoing that the frame of the cot when in its open position is amply strong for the use to which such cots are put, while at the same time said cot when folded occupies but little room and a large number of cots may be stored in a relatively small space.

The construction embracing the side rails, consisting of the stationary intermediate sections A, to which are rigidly connected the intermediate supporting-bars C and the end sections A A, which are hinged to said intermediate sections and to which the head and foot supporting-bars are hinged, is of considerable importance, as said construction provides a rigid connection between the intermediate and outer ends of the cot, which prevents the same from sagging at its center when fully opened.

The detachable connection of the canvas support with the side rails .is of considerable importance for the reason that it enables the canvas to be readily attached to and detached from the frame. The frame, which is desirably made of metal, will obviouslylast longer than the canvas, so that in the life of the frame several canvas supports will be required. Said canvas supports may be made in quantities and sold at a low cost, whereby the canvas supports may be renewed at a slight expense and the work of removing the worn-out canvas supports and applying new ones to the frame may be easily done by any one without requiring special skill.

It is obvious that changes may be made in the structural details illustrated without departing from the spirit of my invention, and I do not wish to be limited to such details except as hereinafter made the subject of speeific claims.

I claim as my invention 1. A folding cot comprising angle-bar side rails each consisting of an intermediate stationary section and two end sections, the webs of the end sections overlapping those of the stationary sections and being hinged thereto and the adjacent ends of the stationary and end sections being formed to constitute stops which are engaged when said sections are in alinement to prevent intermediate sagging of the rails, supporting-legs for the head and foot of the cot each consisting of two bars which are crossed and hinged together between their ends, said bars being hinged at their upper ends directly to the ends of said side rails in a manner to swing toward and from the center of the cot, and the hinged connection transmitting weight from said rails to the legs, legs attached rigidly to the intermediate sections of the side rails and a flexible support attached at its margins to said side rails.

2. A folding cot comprising angle-bar side rails each consisting of an intermediate stationary section and two end sections, the webs of the end sections overlapping those of the stationary sections and being hinged thereto and the ends of the flanges of the end sections abutting against the ends of the flanges of the stationary sections when the sections are in alinement, supporting-legs for the head and foot of the cot each consisting of two flat bars which are crossed and hinged together between their ends, said bars being hinged at their upper ends to the ends of said side rails in a manner to swing toward and from the center of the cot, like cross-bars attached rigidly at their upper ends to the intermediate sections of the side rails, a flexible support and fastening devices on the inner sides of the webs of the side rails, the margins of said flexible support being folded inwardly and upwardly beneath the margins of the webs of the side rails and engaged with said fastening devices.

3. The combination with the crossed and pivoted supporting-bars at the head of a folding cot, of parallel, vertical rods hinged at their lower ends to the lower ends of the supporting-bars and having sliding connection at their upper ends with the upper ends of said bars, said rods being adapted to afford a support for a pillow-rest.

4. A folding cot comprising side rails, each consisting of an intermediate stationary section and two end sections which are hinged to the stationary section to swing toward and away from each other, pivoted and crossed supporting-bars at the head and foot of the cot which are hinged at their upper ends to the outer ends of the hinged sections of the side rails, like supporting-bars which are rig idly affixed at their upper ends to said intermediate stationarysections and vertical rods pivoted to the lower ends of the supportingbars at the head of the cot and having sliding connection with the upper ends thereof, said rods being adapted to afford a support for a pillow-rest.

5. A folding cot comprising side rails, each consisting of an intermediate stationary section and two end sections which are hinged to the stationary section to swing toward and away from each other and provided with shoulders which are adapted to engage shoulders at the ends of the stationary sections when said sections are in alinement to prevent intermediate sagging of the rails, pivoted and crossed supporting-bars at the head and foot of the cot which are hinged at their upper ends directly to the outer ends of the hinged sections of the side rails, the hinged connection transmitting the weight from the side rails to the supporting-bars, like crossed and pivoted supporting-bars which are rigidly attached at their upper ends to said intermediate section, and a canvas support extending between the side rails and fastened at its margins to said rails.

In testimony that I claim the foregoing as my invention I afflX my signature, in presence of two witnesses, this 10th day of June, A. D. 1902.
