ToJaZZavhomtmaiy coiwernw- Q v Be-it known that L iGnonen COBA ,a c ti- Zen of the United States, residing at Salt Lake City, in the county of :Salt Lake and State of Utah, have invented certain new and useful Improvements in Folding Cots;

and I do declare the following to be a full,

clear, undexaot description of the invention; such as will enable others skilled in ,theert to which it appeiztains ;to: make and MSG the. s me. s This invention. jrelzntes to :an H improved folding Loot for use in (camping and oneqobject of the invention is to provide snot havingimproved construction in. folding side bars and looking means for releasably hold- I D p for releasebly hold-mg an intermediate sup-i ing theside herein an extended position and further having intermediate supporting legs pivotally connected i with [the folding side,

the end bars thus providing a spring structure 7 which will be stretched tight when the end bar 2 is'drawn along the side bar sec-' tions 6 and secured by keys 8 passed through openings 9 formed in the end portions of the sections 6 as shown in Figs. land 4:,

If it is found that the ropehas been stretched too tight or has not been stretched tightly enough, the securing pins-or keys 8 will be removed and after proper adjustment ol the bar 2 has been made, the keys replaced in a second set of openings. :f. a

As prevlously polnted out, the side bars will each beformed in two sections and 6 and will be formed from metal-tubing or pipe. I The section 6 has its inner end portion split for a short distanceandbent t0. provide-ears 10 perforated as shown at -11 to The second section 5 has its innerend portion split longitudinally to provide anelongated cross-shaped seat'or pocket having upstanding walls 12 each of which will be provided with alined openings 13 and 1% and one of-which will be provided withan opening 15; The innerend portion of the sectionfi fits into the pocket or seat of the section 5 and a pivot'pm is passed through the openings 11 and l 'thuspivotally connecting the section G'with the section 'lVhen' the sections of the side bars are swung to the extended position',.tl1e opening 16 formed in the section 6 registers with the opening'l5 formed in the section-5.- In order te support the side bars between-theend bars there has been provided intermediatesupa aorting le s 17 each of which is formed from r. 2:) 1

a tubeor length of pipefiattened intermedn ate its length as shown'at 18 and perforated as shown at 19 so that the depending-arms 20 at the ends of thebracing bar21 may fit flat againstthe intermediatesupporting legs 17. Each of these heads is provided with a slot 22 cut between the side flanges provided by thechannel'bar construction of this bracing bar. Therefore when-the bolts 23 which are mounted in the openings 19' are engaged by the depending heads of the bracing bar with the bolts positioned in the slots 22 and "the heads of the bolts engaged by 'theside flanges-oi the bracing bar; the securing nuts 24 may be tightened thus securely but-res leasably holding the bracing bar in engagement'with the intermediate supporting legs;

Theupper end portion or the'p'ipe forming each intermediate supporting leg "will be split longitudinallyand then put and bentto provide 'spaced arms whiclrwill extend upon opposite sides of the seat at the inner end of the side bar section Openings are formedin the side arms-25 to receive 7 V rivets which pivotally connect the support:

111g leg with the side bar section and these side arms will further eachbe pro\' idedf'w1th an opening 27 and one of them willbe provided with aniopening'28 to register with the alined openings 15 and 16 when the supporting leg is swung to the operative position as shown in Fig. 1. p a When the supporting legs are inthe operative position and the sections of the side bars extended, it is desired to securely lock the parts in the operative position. Therefore each or the supporting legs will be provided with a latch constructed as shown in Fig. 6. .This latch is provided with a shank or stem 29 which will be slidably mounted noted that the tooth 83 has its, outer face curved longitudinally thus providing a cam face w hich cooperates with the curved cam faceof the seat of side-bar section 5 to move the latch against the action of the spring 30 whenswinging the supporting leg to the operative position. As this supporting leg is swung to the operative position, the latch is moved against the action of the spring and willmove outwardly through the opening 28 until theopening 28 registers :withf the two openings '15 and- 16i The spring 30 will then cause the latch to niove inw'ardly to positionthe tooth'33 in the registering openings 28 and 15. This will securely lock the supporting legs'and sections of the side 7 bars in the operative position. It willthus be seen that there has been provided a folding cot in which-the end bars may be connected with theend portions ofthe sidebars and the supporting legs then swungto an operative position'w'ith the tooth of the latch extending through the openings 28 and 15.

The side bar section'6 can then be swung downinto the scatter the sectio1r5 thus tightly stretching the rope which forms the spring structure 7. As the side barsections 6 move into theseats of the sections 5, the

sections 6 through engagement with the curved faces'o'f the teeth 33 of the-latches will -1nove thel'atches outwardlypuntil the openings 16 register'withtheopenings "15, at

which time the springs will return the latches to the locking position The sup porting legs'17 may thus be moved tolthe operative position either before or-after the side bar sections 6 are swung down to the extended position. When the cot is no longerto be used, the latches will be moved to a "releasing position and the supporting legs swung upwardly against the side bar sections" 5. "The side bar sections 6 will be folded to extend alongthe side bar sections 5 and the end bars 1 and 2 removed. The bracing bar 21will be released and moved out of engagement with the supporting legs and the supporting legs 4: will be removed from the end bars. The elements forming the cot can thus be taken apart and the side bars and supporting legs 17 together with the bracing bar 21 and supporting legs 4 placed to extend longitudinally of the end bars 1 and 2 and the disassembled cotrolled into a compact mass.

I claimr H 1. A cot including folding side bars each having end sections pivotally connected and extending in overlapping relation when in an operative position, and having openings registering when the side bar sections are extended, a supporting leg pivotally connected with one section and a latch carried by the leg and having a tooth portion forextending through the openings of the side bar sections, the tooth portion having a curved face forming a cam surface engaged bythe side bar sections to move the latch to an inoperative position, when the bar sections are swung to an extended position, and-resilient means for normallyvholding the latch in an operative position and moving the tooth into the openings.

2. A cot including folding side bars each having endsections having pivotally connected inner end portions extending in overlapping relation when extended and fitting one within the other, a supporting leg pivotally connected with the inner end portion of the section receiving the second section 'when extended, the legand bar-sections being provided with openings reglsterlng when vthe bar sections and leg are in an operative and a spring normally holding the latch in an operative position for extending through the openings.

latching means, in'the' form of a, pin slidably carried by the leg'and having a bent end for passing through'the registering open-' ings, and a spring normally holding the latch in an operative position for extending through the openings, the end of the pin.

passing through the openings having a cam.

face for movingthe latch to an inoperative I position against the action of the, spring g I ,50 4. The structure of claim 2 havingrthe' when a bar section is swung to an operative position, and engages the cam face of the latch.

spring structure carried by the end bars,

5. A folding cot comprising end bars, a

folding bars each having pivotally connect-1 ed sections, an intermediate supporting legs for each side bar pivotallymounted upon its plvotally connected sections for movement into and out of an operative position and common latch means for releasably hold ing the side bar sections and intermediate leg ln an operative pos1t1on.'

In testimony vwhereof I have hereunto set my hand.
