T all whom it may concern:

Be it known that we, VVILLTAM V; Don's- LAS, VVALLACE R. DoUeLAs, lYlARGELLA Dono- LAS, VVILLIAM H. DOUGLAS, and DONALD Q. DOUGLAS, citizens of the United States, re-

siding. at Crete, in the countyofSaline and State of Nebraska, have invented certain new and useful Improvements in All-Steel Camp Cots, of which the following is a SPQClfiCELiZlOIlf The rapidly growing use of the automobile for extended touring trips and for camping trips has created a demand for camp furniture of types dlfi ering radically Many of from those of ordinary furniture. these demandshave been supplied, but there I has been an insistent need-of a cot which is peculiarly suitable for the conditions met with on touring trips. The army type of cot is being very largely used for this purpose, but such a cot 1s rickety and uncomfortable in. use, it is short lived and .it has detachable parts which are liable to become lost. In brief, it is our object to prov1de a."

foldi'ng camp cot having a frame of steel construction which issubstantial and rigid I during use and which has no detachable parts. Other objects will be pointed out in the following description.

Referring now to the drawings, Figure 1 is a view in perspective of the cot frame as it appearswhen set up.

Figure 2 is a perspective view of the folded cot. L

Figure 3 is a plan view of the cot frame as it appears when partly folded or unfolded y 7 Figures!c is a viewin perspective of'the corner of the cot frame having av fixed pivot.

Figure 5'is a perspectiveview of one corner of the. cot frame showing the sliding pivot.

Figure 6 1s a sectional view of the end rail with the legs folded therein.

I Figure 7 is a sectional view of the middle joint of the cot frame.

The cot frame includes two side rails, each composing a section 10 and a section 11, the two sections of the pair being'each pivotally. secured to the clip 12 as shown in Figure 7. The clip 12is in channel form and serves to hold the sections 10 and 11 in alignment in the set-up cot. has secured thereto a pair of ears 13 for supporting the middle leg "structure of the Each clip 12- cot. The leg 14 is made from a single piece of channeled steel while the other of the legs comprises two portions 15 and 16 connected by a pair of webs 17. A pivot pin passing through the webs 17 and through the leg 1 1 secures the two legs togetherin pivotal relation'and in such a manner that when they-legs areffolded they are parallel to each other andthe sections 15 and 16 are .on opposite sides of the leglt. The pivots for the sections 10and 11 with the clips 12 are spaced as shown in Figure 7 so that the two sectionsof the side rail fold against the middle leg structure This construction, however, is similar to that of the army type of cot, and is described here merely to point most completely closed except for a slot run mn'g lengthwise in their upper sides. At the outer extremities of each of the sections 1.0 s rigidly secured a latch plate 18 as shown in Figures 1 and 4. At the outer extremities of the sections 11 is a latch plate 19" having two pins 20 which have a sliding engagement with the notches in the sections 11. The latch plates 18 and 19 are identical 1n outline, but they; differ in that the plate 19 has a sliding instead of a fixed relation with its section and also in that it is provided with a-sliding pivot as shown in Figure 5. Theend rails 21 are secured to the side rails through these latch plates, the plate 18 having'a fixed pivot on the end rail and the plate'19 having a sliding pivot, as

shown in'Figure 5. The end rail 21' has an upwardly projecting pin 22 which engages a slot 23 inthe latch plate 19, the slot permit ting movement ofthe 'end' rail but limiting that movement to the width of they side rail.

The legs 24 are'alsoimade of channeled steel and they are pivoted directly, to the end rails, a-portion of the upper surface-of the end rails being cut away to permit the legs to assume their operative position at an inclination to the'cot frame. 5 The legs 24 haveupwardlyprojecting ears 25' which seat in these cutaway portionsof-the end' rails when the cot is set up. Thelatch plates have notches which register "with the cut away portions of the end'rail when the cot is-set up, and the ears seatin'these notches the legs releases the. plates 18 and 19 from ,latching engagement permitting a pivotal apart.

. movement of the end rail 21 on the latch 18 and permitting the latch-plate 19 to slide on the section 11. Before the latch .plate permitted to slide on the section 11 the: r

.two of the said connections at diagonally opposite corners of the frame being fixed end rail must be moved to bring the pin 22 to the outer end of the slot 23, this move ment bringing the end-0f the end rail slightly within the inner side of. the section 11. As the two plates 19 are moved inwardly there is a parallel movement of the twoside rails, gradually bringing them, into juxtaposition. At the same time the middle legs are folded on each other so that when this operation is completed the structure has the form of :1 fl", the pair of side rails forming the bar of the T and the. folded middle legs forming the leg of the T. There remains only. to fold the side rail sections on their pivots in the clips 12 so as to bring the side ail sections 1and the end rail sections into parallel relation with: the. middle leg struc ture.

The operation of settingup thecot is very simple. The first step brings the parts into the position shown. in Figure 7,.af'ter which the side rails are spread by pulling them The spreading of the side =ra1 ls causes the slidingcof the plates 19in the grooves of the section 11 until the end rails are positioned at right angles to the side rails to form a rectangular structure. The latches 19 shouldshavesuch. a position at 1 the end of their sliding movement that the inner walls of the cut away portions "'willlbe lflushlwith the outer ends of thesections -11, .so as to permit the ears 2510f the. legs, 24

to enter. the cut awa oortions and to latch the parts. a It should be here noted that this latch to a certain extent dependsoonthe weight' placed upon the cot.

T he heavier the occupant the more rigidlywill the latch hold the, parts-in fixed position.

The cot,,when set up, is a full length cot J of 76 inches, having a width of twentyseven inches. then folded it occupies an fidlIlOSd insignificant space. Its folding and unfolding operations require only a few sec- All of its parts are secured detachable parts. Every portion of the frame is made of steel, which materially reduces the weight but at the same time gives added rigidity and wearing qualities to the frame, In the size in which We construct the cot it supplies the demand for a single cot. It is, however, possible to construct it as a cot of a greater width, or in fact to increase its width to bed size.

'Having thus described our invention in terms which will be readily understood by others skilled in the art. to which it pertains, what We claim to be new and desire to secure by Letters Patent of the United States is 1. A collapsible bed frame having end and siderails forming a rectangular structure, pivotal connections between the end and side rails at the corners of the frame,

pivots and the other two of the said connections being pivots which are adapted to slide lengthwise of the respective side. rails, the arrangement being such that duringthe collapsing movement of the frame the side rails maintain their paralleh relation.

2. In a collapsible bed frame, end. and side rails, plates rigidly securedto said side "rails at diagonally opposite corners of the frame, other plates slidably secured to said side. rails said secondvnamed plates being diagonally positioned in the set-up bed and on the sides of the bed opposite said first named .plates,.- said end wrails being each pivotally secured at .its'opposite ends to one i of said fixed plates and to one of said slidable plates.

.3. bed corner including a side rail and an end rail which is adapted to rest against the extremity of the side rail, said end rail being in channel. form, a leg p-ivotall secured to said end railso as .tobewfoldable therein, a: latch plate slidably secured to said side rail and pivotally secured :to said end rail, said: end. rail having limitedsliding movement relative to said latch plate, the upper wall of said end rail beingicut away at its extremity. and. said latch plate being provided with anotch which isadapted. to, register with the cut away portion of the said endrail when the bed is setup, and an ear on said leg, said ear being adapted to enterthe registering notch and cutaway portion of said latch .plateiand end rail respectively to latch the. said parts. against accidentaldisplacement, said ear also serving as an abutment for the leg when the bed is setup.

In witness whereof we aflix our signatures.
