SHE SHEET 2- UNITED STATES FATE T was cor-BE To all whom it may concern:

a citizen of the United States, resident of Minneapolis, county of Hennepin, State of Minnesota, have invented certain new and useful Improvements in Cot-Beds, of which the following is a specification.

The object .of my invention is to provide a bed designed particularly for the use of soldiers at an army post or cantonment and also useful for campers generally and for hospital purposes or wherever a substantial bed of this type can be used.

A further object is to provide a bedwhich will have no loose swinging parts when it is .knocked down or folded which might be broken off and lost in transportation;

A further object is to provide a bed WhlCh can be folded into compact portable form without separation of the parts and when" unfolded or expanded will be extremely rigid and capable of withstanding the rough, hard usage to which a bed of this type is frequently subjected.

A further object is to provide a bed of strong, durable construction, which will be comparatively light in weight and easily transported from place to place.

The invention consists generally in various constructions and combinations, all as hereinafter described and In the accompanying drawings forming part of this specification,

Figure 1 is a side elevation of a bed embodying my invention, V

Fig. 2 is an edge view showing the bed folded,

Fig. 3 is a bottom view of the bed unfolded, ready for use. I

Fig. 4 is a bottom view of the bed folded and strapped together for transportation,

Fig. 5 is a transverse sectional view showing the position assumed by the rails and legs when the bed is folded,

Fig. 6 is a detail sectional view, showing the manner of mounting the legs on the side rail of the bed,

Fig. 7 is a transverse sectional View through one of the rails, showing the pre ferred manner of securing the flexible bed bottom to the side rails of the bed.

In the drawing, 2 represents a pair of side rails having longitudinal grooves 3 in their outer faces to receive rods 4 which are inserted into loops 5 provided in the longituparticularly Specification of LettersPatent.

dinal edges of the flexible bed bottom 6, composed preferably of canvas or similar material. The upper edges of the rails are preferably curved to present rounded surfaces 7 on'wliich the bed bottom rests. For securing the rods 5 within the grooves'Tin the rails, I provide a series of spring wash ers 8; secured by suitable means,".such as screws 9, to the rails'and overlapping the grooves 3 and bearing on the loops of the bed bottom, thereby locking the rods in the grooves. WVhen' a load is placed on the bed bottom, the pull thereon will be imparted to the rods for drawing them against'the upper walls of the grooves, the function of the spring washers being to hold the rods within the grooves and thereby the strain of the load will be transmitted to .jthe rails. This is avery'simple, economicalmeans for fastening the bedbottom in place, for by loosening the screws the bottom may be easily and or repairs. ,7 1.

I provide the usual number of legs 10 for these rails. These legs have angleplates 11 mounted on their upper ends andla pping by the outer facesfof the rails 2 and connected therewith by pivot pins 12. These plates allow the legs to be swung inwardly and lie against the under fa'oes of the side rails, as shown in Fig. 2, the angleof'said plates"be ing such that when the legsare swung to their folded position they will The parallel and ineontact with the sidera'ils and fit snugly thereon to allo'w the bed to, be folded into compact form. The projecting ends' of quicklyremoved for substitution 1 the plates have bosses 13 pressed therein and rivets Hare mounted in the side rails and have heads for entering the recesses formed by said bosses to hold the said legs in their open or unfolded position, there being siifficient spring to the metal ends of the plates to cause them to bear on the rivet heads with sufiicient pressure to hold them in place. When, however, the leg is grasped, it may be rocked back and forth on its pivot, the

spring plates sliding over the heads of the rivets to allow the leg to be moved to its open or closed position.

Each leg is provided with an inwardly projecting lug 15 near its upper end and a similar lug 16 near its lower end. Links 17 are pivotally connected at one end with the lower lugs 16 and at their other ends are pivotally connected to bars 18 whichin turnare pivoted to-the lugs and at the point where the and 21 also form a toggle for locking the bars 18 in their unfolded position, said links being capable of folding up, jack-knife fashion, as indicated in Fig. 4 for the purpose of allowing the toggle bars and links to be folded in upon one another and the bed contracted to a compact or folded position. There are, of course, a pair of toggle links and bars. at each end of the bed between the opposite legs at their front andrear ends and in setting up the bed, it is only necessary to draw the rails apart, straighten the toggle links 17 and 18 and lock them in their expanded position by straightening the links 20 and 21.

I prefer to provide straps 23 mounted on the legs by means of loops 24 by means of which the legs and rails may be bound securely together for transportation of the bed. *When the legs are unfolded, the ends thereof will bear squarely on the under faces of the rails, as indicated in Fig. 6, and form a substantial support therefor, the legs being swung out to a point where they will be slightly out of the perpendicular to prevent accidental collapse and spreading of the opposite legs will be positively prevented by the arrangement of the toggle bars and links between them.

In various ways the details of construction herein shown and described may be modified and still be within thescope of my invention.

A bed of this type is particularly valuable for army or camp use from the fact that there are no loose swinging parts, such as hooks or braces, when the bed is folded to be broken or torn off in transportation. Every member folds into compact form, the legs being held at both ends and prevented thereby from swinging or swaying and becoming damaged whenthe bed is folded for transportation.

I claim as my invention:

1. A folding bed comprising side rails, a flexible bottom secured thereto, legs for said side rails, flange plates secured to the upper ends of said legs and embracing the corners thereof and projecting upwardly on each side of said rails and having a pivotal connection therewith at one side of the longitudinal axis of said legs, said plates having bosses formed therein, said rails having heads for entering said bosses for temporarily holding said legs in place and the upper ends of said legs be ing seated against the underside of said rails when said legs are unfolded.

2. A folding bed comprising side rails and a flexible bottom secured thereto, legs pivoted on said rails, bars pivoted one upon the other and having a pivotal connection at one end to one end of said legs and a pivoted link connection at their other ends with the other ends of said legs, and toggle links having their inner ends pivoted together and their outer ends pivoted on said bars, said links, when in alinement, locking said bars intheir expanded position. r

8. A folding bed comprising side rails and a flexible bottom secured thereto, legs for said side rails, said legs being mounted in the plane of said side rails to swing up against the under surface thereof when not in use and having theirupper ends bearing on the under surfaces of. said rails when turned down to a supporting position, bars pivotally connected with the upper portions of the op posite legs and projecting inwardly and hav-= ing their inner portions pivoted together, and links pivotally connecting the inner ends of said bars with the lower portions of the opposite legs for bracing and supporting the upper and lower ends of said legs when they are swung down to a working position, and toggle links connecting the upper portions of said bars and adapted, when unfolded, to lock said bars in their open, position.

In witness whereof, I have hereunto set my hand this 2d day of November 1917.

ARTHUR 0. HUBBARD.
