- .To all whom t may coneerm" Be it known that I, BYRON O. LEAv1TT, a citizen ofthe United States, residing at Den# ver, in the county of, Denver 4and State of Colorado, have invented 'a certain new and useful Improvement in Combination-Cuts; deolare `thefollowin to be a exact description othe invention, such as will enable others skilled in the art to which it appertains to vmake and use the same. 4

This `inventionrelates to improvements in combination-cots. y

One of the objects of the invention is the construction `of a lcot which is provided with "an adjustableback, said cot capable of being used as a hammock or atable.

- joints at middle of legs.

, are the smaller legs,

j With this and other objects in view the invention consists of certain other novel constructions, combinations, and arrangements of parts as illustrated inv the accompanying drawings, and more particularly pointed out in the claims hereto appended.

In the drawings, Figure 1 is a perspective view of the cot with an adjustable chair-back and tent. l Fig. 2 -is a perspective view of the cot used as a table'. Fig. 3 is a perspective view ofthe cot with an adjustable back used as a hammock. Fig. 4 is a plan view of the cot-legs telescoped and partial details of Figs. 5 and 5a are vdetail views of the joint connections at the middle of the legs. Fig. 6 is a fragmentary view ofthe central portion of the legs, showing another: embodiment ofthe j oint'or con-y necting means employed for securing the legs together intermediate their ends. Fig.

7 1s a fragmentary plan view of the sides and ridge-pole, -showing the means by which the telescoping sections are fastened to ether.v

Fig. 8 is alfragmentary plan view of t c sections of the sides and end piece telescoped. ig. 9 is a'ragmentary side view of the tent upright and parts of the tent-frame. Fig. 10 is a side view of the cross iece Which is employed for holding parts o the tent-frame in position.

Referring-to the drawings by numerals, 1 1 designate the larger legs ofthe cot, While 2 2 which telescope within the legs 1 1. The side bars 3 of the cot are detachably connected to the end bars 4. The cot-frame is vprovided with a transverse brace 5. .The -rame of the cot is covered, preferably, by a canvas 'covering 6. The

the back in an adjusted position.

will be hereinafter fu1lydes'cribed,

l end bars.

canvas coveringl is provided with apertures 7, within whic is positioned the lacing 8. Upon the side bars 3 of the cot there are secured triangular brace members 9. The brace members or frames are secured to the side bars by means of clamps l0. lEach of the triangular brace members 9 is provided with notches 11, formed upon its horizontal portion.

The adjustable back of the cot comprises` side bars12, which are pivotally connected, as at 13, preferably,

by means of thumb-screws. A removable rod 14 is'itted into notches 11 for holding The side bars 12 of the adjustable back are connected at their upper end by'a top cross-bar 15. The side and top lbars are covered, p'referably, by a canvas covering 16.4

U on each of the endcross-bars 4 of the cotame there is 17, which supports one ofthe tent-uprights L18. Near the upper end of each of the up-v rights 18 Athere are secured scmitubular members 19, Fig. 9, which are adapted to be secured apart, Fig. 1, by means of a crosspiece 20. Eachof the uprights is provided with a notch or cut-out portion 21, within which is positioned the cross-piece 20. Each of the uprights 18 is provided with a reduced extension 22, which projects through an aperture formed in ahorizontal ridge-pole 23 of the tent-frame. reduced rights 18 `will normally retain the ridge-pole j to the lower portion of4 'the sides of the brace members or frames 9 It will be obvious that the portions or extensions 22 of the up# positioned a double clamp 23 in position. The tent-frame is covered by a canvas to 24.

The side an end bars of the cot-frame are detachably connected by means of threaded' extensions25, formed upon the ends of the sidebars, said extensions 25 .being positioned Within apertures formed in the ends of the Upon each ofthe threaded extensions 25 there is positioned a thumb-screw 26, which is adapted to be employed for securing the bars together. Suitable meansas, forinstance, rope 27is employed at each `end of the cot for swinging the Vsame when it 1s desired to use said cot as a hammock. One of the cross-sections is rovided With a locking detent or notch, -w 'ch is provided with IOO IOS i parts 28 and 29. A lug 30 is formed upon one of the sections and is adapted to be fitted into the locking-notch of the other section.


Referring particularly to Figs. 5 and 5, i j


`provide clamp. The clamp 30 is provided with a swinging thumb-screw 32, employed for iX- i edly'securing the sections of said clamp together. A bearing-surface 33 is formed upon the clamp. The clamp 30 is provided with ya tongue or dovetailed tenon 34, which is adapted to be positioned within asimilarlyconstructed groove of the'clamp 35.- Thel clamp 35 is provided with sections which are pivotally connected by means of a hinge 36.

The clamp 35 is similarly constructed to clamp 30 and is therefore provided with 'a swingingi thumb-screw 37 The clamp 35 is with a bearing-surface 38 and with projections 39.

Each of the legs 2 is provided with a double clamp 40. The double clamp 40 is provided with a thumb-screw 41, which secures said clamp upon the leg. 42 indicates the opening within which is positioned one of the side bars of the cot. The movable portion 43 of the clamp 40 is capable of being swung .to permit of the positioning of the clamp in engagement with the side bar 3. The movable portion 43 is hinged at 44 to the clamp. A swinging thumb-screw 45 is employed for fastening the movable portion 43 in position. The legs liare each preferably provided with an integral clamp 46, which is provided with a movable portion 47, hinged at 40 to permit of said portion 47 to be swung outwardly to I allow -ofthe positioning of one of the side bars within the clamp. The removable portion of the clamp is secured in a fixed position by means of a swinging thumb-screw 49. The

.clamp on one of the legs is made removable,l

so. as to make the telescoping more compact yand enable the whole to be packediin a smaller space. When the clamp at tlie eind of the leg together wiltLh the portion of thefrhiddle joint or clamp o leg 2 are both; r moved from saidleg, the whole of the leg itself will fit into leg 1, therebymaking a considerable saving in length. Of course it will be obvious that clamps30 anld 35 may be removed from the In the Iembodiment depicted in Fig. 6 I have shown a bolt 50, passing through the legs. A th'unib-screw 51 is positioned'upon one end of the bolt. Interposed between the legs and upon the bolt 50 are clamps 52, which are `held together by means of said bolt and thumb-screw. The engaging portions of the clamps are flat.'

Referring' particularly to Figs; 9 and 10, the cross-piece 20 vis provided ywith a notched portion 54, which engages the similar portion 21 of the upright 18. Each end of the crosspiece 20 is beveled, as at 55, for fitting the inner convexed portion of the hinged semitubular members 19.

Within the legs, as shown in Fig. 4, there may be inserted all of the sections of one side bar, together with one end bar of the cot, the sections of vthe side and end bars being telescoped, as shown in Fig. 8. The same is done with the other pair of legs and the other side and end bars, so that lthe complete frame of the cot, with the exception of the middle brace 5, will be contained within two short pieces when the whole is telescoped. The pivotedends of the semitubular -members 19 should be soconstructed as toleave a small s ace between parts 19 and upright 18 when tlie same are folded together, Fig. 9. The space should be just the thickness of the tubfing used. This manner of construction is necessary, because the whole tent-frame telescopes into one piece. One of the uprights is made so as'to lit within the other. All of the sections ofthe ridge-pole telescope one withinthe other the same as the sections of the side bar, and when thus telescoped they fit within the smaller upright. bular members 19 are made so that they fit' If the semitu-` closely to one of the uprights when folded then when the other upright is telescoped over 18 it must go Within part 19, and unless a suliicient space is left for it to do'this it will force this part out at an angle vinstead of allowing them to' lie fiat against the upri hts.

While I have lnot specifically depicte the telescoping ofthe tent-frame, the principle is exactly the same as that shown in Figs. 4-and 8 for the frame of the cot. The same principle applies to the frame of the back:- ofthe chair, the four pieces telescoping into one by reason of the fact that each is of a'different size.
