Foi` instance, should the bed have been particularly of the folding or collapsible type usedso many times that a very objectionable sag which is adaptable for use in connectionV with may have occurred in the supporting sheet, the automobiles as well as for camping and similar cross tension members can be adjusted so as to Y 5 'purp0ses l restore the original cross tension of the' sheet. 60

After the brace is set in place (Fig. '7) it is held in placeon the stud by a cotter pin 17.

These braces establish the extended or open position of thelegs 9, 10. The legs will be substantially upright (Fig. 1),V but it is preferable that they shall slant outwardly toward'the head and foot ofthebedv so as to `make 'amorefsecure stand for -the bed frame. It will be understood that by removing the cotter pins 17 fromthe studs 16 the parts can be swung on the various pivots .11, 14 into a nested position within the confines lof the side rails 2, 3 as shown at the right of Figure 6.

Cross tension members 13, 19` (Fig. 6) span the pairs 0f legs 9, 10, serving to maintain a 'given spacing of the side rails 2,'3 'and acting as-substitutes for the rigid head and foot cross pieces of the frame. The members .18, 119 perform every function of such cross pieces, but unlike the usual cross pieces, occur both below or in spaced relationship tothe cover 'l and are relatively remote yfromthe ends f'the coverso that the head and heels of the user are guarded from a hard obstruction. l

Eachtension member`18, 19.is alike, and the de-k scription 'of the memberflwill sullce for both.

This member is made of angle material and comprises two components 20,21 (Fig. V'1). The remote .ends are cutaway toleave flanges 22 through .whichth'e comp'onentsare pivoted' to the legs 9.as

at 23,5and'lto'prov`1de.shoulders`24 which areintended to'abu't theiadjacent edges of the'legs 9 and prevent the swinging'of 'the components 20, 21

upwardlyV (arrows .25) in 'the direction of the cover '1.

VIt `is permissible 'to swngthecomponents 26, 21 downwardlygor away from'the 'cover "I, prerparatory'to. collapsingthetbed ioriolding.Y 'Were it'not for'the shoulders 24`there'would be the-possibility of the components-20, 21-'being swung to- 'ward the cover'l at sometimawith the likelihood of tearing the cover. Theshoulders 24'areproduced'by simply cuttingouta smalljpartof each component, but "when thecomponents are pivot- 'ally secured the shoulders effectually prevent the 'undesired 'upward' movementtoward the cover as previously mentioned.

The member lhaswhatmight be called a hook and slot connection betweenthe 'overlapping' near ends of the'components'(^1ig.n'l) The component 21 is cut out at'26 (Figs. "land`-8),'then bent to produce a hook'2'7. `Thisfhook is more'inthe nature of atongue-atrighty angles to the bodyo'f the component 21, butit is quitecorrect to saythat the tongue 2'7 is'hooked'into anyone of a seriesof slots 28inthecomponent`2`0, therbyftol establish `the extendedadjustmentof the tensionmember -18. 'A band.29fslldably embracesithe vmember 18 (Fig. 1) andr isiintended toiflt vover the endsof thev components 20, 21 so asztohld the hook ortongue 2'74 in engagement withragiven slot 28;

Should the :user xprefernotzto-have'the cover '7 stretched tight'across the'side rails :2, 3 he can undo therhook-and vslot connection (Fig. '1) and readjust it so thatthere i-will -be a more or less pronounced sag in thecover. `*On the sameprinciple, should thecovertbeworn into an undesirable sag, the hookand :slot connection .would be undone andreadjusted .until the sag disappeared.

For .this purpose the component 20 (Fig. '7) will be provided with as many slots as will ordinarily be necessary tomake any ladjustment within'reasonable limits. It'will'beunderstood that 'when ,theband 29 is `once slipped'toward the center over each component"20,'2`1`the member 18 (also gradual incline. 'folded under in the event that this was necessary yto properly stand the bed in certain types of automobiles. When the bed is doubled up in substantial A-,form (Fig. 3) it will serve as a back rest for a-person sitting on the ground. The adjacent pairs of legs 9, l0 Ymay then be so engaged with the ground as to serve as prongs in order to assist in keeping the bed in its doubled standing position. y

.Reverting to. the hinging together of .the 4bed sections,.it is t'o be observed that the cover 7 is vcut away at 30 (Figs. 1 and 2) .at places adjacent ltothe hinges `5, so as to clear the rails2,'3 Yand avoid any possibility of the medial pucker3 1' (Fig. 6) vfrom getting down between the abutting ends .ofthe side rails and preventing their being opened in Aline -with' each other. l'Ihe requirement `of folding the half sections of the bed upon each ,other makes it necessary to provide a fullness in the center. 'This fullnes disappears as'the pucker 3l on the nether side when the'bed is open (Figs.

.l and 2), but when thebedis stood as in Figure 3 lthis pucker stretches across somewhat, and vwhen the half sections are folded upon eachother the pucker will be drawn taut.

lFigure 9 illustrates a slight modification where- .in the band 29 is replaced by a'bolt and slotfconnection inthe components 2l, 20. The hook 27 and slot 28 arrangement will bethe same as before, but in place of the band'29 there'will be a bolt 32 in the component 21 and a'slot 33 inthe `component 20. 4This maybe anv open-ended slot. `When the desired adjustment at 29, 28 is'made the nut on the bolt 32 will be driven uptight against the component 20 after having seen to it v that the bolt 32 wasin the slot 33, thereby'to 'x the connection.

.component 20 (Fig. 7) and to rloosenthebraces 13 from the studs 16. Thel tension member components 29,-21, legs 9, l0, and'braces 13'will all be .swung together in the proper direction on their pivots so as to lie against the insides ofthe rails 2, 3. The half sections of the bed are then swung over on the hinges'5 and rolled substantiallyinto the shape shown in Figure 4.

Whatv is claimed is:-

In a bed having a supporting sheet, side rails to which the sheet is attached, and legs pivoted to the rails; means to maintain the spacing of the sideV rails hence a given cross tension of the sheet, said means comprising a cross member having partially overlapping components attached to the legs, one of said components Vhaving "slots, a tongue on the other component to be vhookedin'one of the slots,.and means for bringing pressure to bear on the overlapping ends to maintain the engagement of the tongue with the slot.
