To all whom tmc concern: Y y y Be it knownt at I, FRANK,M.SroLL, all citizen of the United States, and aresident of the city and county of Denver and `Statev of Colorado, have invented certain newend useful Improvements in Camp-Stools, `of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which `the invention a'ppertains to make and use the same. My invention relatesfto improvements in camp stools or seats and the primary. object of the invention is to provide a stool or seat which ma be Vcollapsed into a relatively .compact orm and carried inl the poket, traveling bag, orreceptacle` for containing camp equipment. f` i y Another object of the invention is to pro-` vide a strong, durable and serviceable device of this character, which when in its set-up or operative Ostion, and while being; used,

or use towhich the same is; subjected.` y

Another object of the invention residesin `the provision of means for eectivelyextendin the frame of the stool so that it willproper y and evenly stretch theseat proper and `retain the latter inxedpositionilpon the frame and obviate any danger of the collapsing of thestool `frameunder theiniluence `of `weight or strain. W y. Another object of theinvention resides in the provision of a seatliroper for thefstool, which, when the frame is collapsed may `be `a covering or awrapper `for the framle." With these andlotberlobjects in view as will become apparentin' the following `detailed description, the invention will now be y ,described with reference to the accompanying drawing forming a mpart thereof.

n `this,drawiI1g`, igurel` 1s a side elevation view of the [stool Fig.` 2 is aA cross-sectional view taken ,on the line 2--2 ofEig. 1 Figf is a verticalcross-sectional viewof the `frame; Fig. 4 isa viewof the scat proper; and Fi 5l is a detailed sectional View taken on the ine5-f5 of Fig. 4. y

Corresponding andlike parts are referred, to in the ollowingdescri tion and designated in all the `views of t e accompanying' drawing by the same reference characters. y

Let the numeral 5 ldesignate the lseat frame in its entirety, andthe numeral` 6 designate each ofthe four legs comprising `a part of` `the frame. These legs 6 are formed of channel iron. `The numeral 7 designates each of `four seat supporting bars, which pass through slots 8 in the legs 6 by means of pivot pins 9, which passthrough the opposite walls` ,of the legs 6, as well as through the seat supporting bars 7. The slots 8 are formed inthe legs 6 near their upper extremities and the seat supporting bars 7 are pivoted in said slots near the normal lower extremities of the said seat supporting bars. The lowerl extremities of the seat supporting bars 7 are pivotally connected to outwardly extended ears 10 of a block l2, as shownat 11.

:The block 12 is rovided with a central openingll "therein, t rough which a post 14 is receved, the block 12 being adapted to slide lon 'tudinallyupon the post 14in the manner erinafter to be described when the legs `6 and seat supporting bars 7 are foldedor collapsed. The post 14 is provided at its `upper extremity with a block 15, having outwardly extending ears 16, to which the upper ends of the legs 6 are pivotally connected, as

shownat 17. The` lower extremity 4of the `post 1&1 is` provided with a threaded portion ,4118, uponwhich a wing nut 19 is threaded, the said Wing nut 19 being adapted to be` Amoved'upwardly upon the threads A18 and carry the block 12 therewith until the seat supportin bars 7 havebeen laterally expanded su iciently to tighten the seat proper ierein `designated 2O upon the frame of the stool." As the wing nut 19 is moved upwardlyonthe post .14, carrying the block 12 therewith, the legs 6, aswell as the seat a lateral direction upon the` pivots 9. This `action is accomplished by causing the block 12 to move towardthe block 15 and thereby shorten the distance between these two oints. A washer 21 is mounted upon the The seat 2O is formed of leather, cloth or any" other suitable relatively strong flexible material, and reinforcing strips 22 of any the upper ends of seat supporting bars 7.

Metallic members 24 are secured to each extremity of the reinforcing strips 22 by supporting bars 7 aremoved outwardly or in `post11be`tween`the wing nut 19 and block 12.

ico

means of rivets or other suitable fastening devices 25. rlhe outer extremities of these members 24 are provided with hooks 26 leentinwardly to form an angle of approximately thirty degrees with the body of the,

members 24. These hooks 26 engage inthe Y channelsv of'the seatl supporting members 7 at the upper extremities of the latter and retain the seat 20 on the seat supporting members 7. The `movement of the block 12 in the direction of the block 16, Aas heretoforeV described, results inetightly stretching the seat proper due to the outer movement of the'upper extremities .ofthe seat supporting membersf. Thesemetallic members 24 and Y their hooks 26 serve as a strong and durable method of engaging the seat 2O with the seat supporting bars 7, and Venablethe tension to be Vevenly applied to Y,the four corners of the seat 2O.

as well as the `seat supporting bars 7 areV moved parallel witheach other.l In order yto ac'complishthis movement, it is necessary for the seat 2O to bie removed from the seat supporting bars 7. VVVhen this is done, the

parts [of thefseat, supporting bars beyond Y the pivots '9 may be` moved downwardly Y until they Fare received within the channels ofthe llegs. When'the seat supporting` bars,7 are thus moved downwardly, there will be a simultaneous movement of the legs 6 toward the seat supporting bars 7, and the block 312 will be ,moved upwardly on the post 14 until i the same reaches a position where the seat supporting bars 7 will occupy a position parallel with the legs 6.

Before proceeding'further, it may enable a better understanding ofthe invention to Isaythat the lobjects intended to be accomplished are substantially the same as those recited in connection with United States Patent Number 1,157,795, patented October 26th, 1915. Also the construction embodied in the present invention is of a similar nature t'o-theiconstruction described and disclosedfinv this patent ;v however, there are important departures in thecons'truction enablin-gv a` more convenient use of the stool and ymakingthe,sameof a more permanent construction; l y f Whenjweightorl'strain is yplaced on the seat'20, the tendency is to draw the upper extremities lof the seat supporting bars 7 toward eachother, and thereby cause the block 12 to movedownwardlyv upon the post 14, butthis inward movement of the upper` extremities of the seat supporting bars 7 is vvstopped, by, means of the wing nut 19, which serves as a stop against the downward' movement of the block 12 upon the post 1 4. This is an important departure from the prior state of the art, as there is no adequate means employed for obviating this diiiiculty. Furthermore, there is no adequate means employed in the prior art for stretching the Seat 2() and retaining the same in a condition of tautness upon the frame. However, the wing nut 19 threaded upon the post 14 in the manner hereinbefore described obviates all of these diliieulties and enables the seat 20 to be stretched evenly throughout its area and to be maintained in such stretched condition against the influence ot' weight upon the seat 20. By threading the wing nut 19 upwardly upon the post 14, any de gree of tartness upon the seat 20 may be accomplished, and at the same time, the seat 20 is securely fixed to the seat supporting bars 7 and enables it to withstand the strain incident to the stretching by rcason of the metallic members 24 and their hooks 26.

When the stool is not in use and when the frame 5 is collapsedy as hereinbetore dcscribed, the seat 2O is, of course, disengaged and becomes a separate part. The seat 2() may then be wrapped around the frame 5 with the latter in a folded condition, and

thereby form a covering for the frame 5.

aces 29 are permanently secured in perforations 30 near one edge oi the seat 20, and by means of which laces the seat 2O may be tied around the frame 5.

In collapsing the frame 5, it will be necessary to move the wing nut 19 outwardly on the post 14 so as t0 release the tension upon the seat 20 by permitting the upper extremities vof the seat supporting bars 7 to move toward each other, and thereby enabling the seat 20 to be removed. Further adjustment of the wing nut 19 is not necessary in order to collapse the frame 5 in the manner hereinbefore described The upper extremities of the legs G adjacent the slots 8 are provided with wings'or flanges 31 thereon whereby the portions of the legs 6 adjacent the slots 8 are reinforced in order to compensate for the material taken away in order to form the slots 8.

While I have described and illustrated herein a specific form of my invention, it is understood that the same may be modiiied and varied without departing from the spirit of the invention or the scope of the appended claims.

Having thus described my invention, what I claim and desire torsecure by Letters Patent is 1. A lcamp stoolcomprising legs and seat supporting bars pivotally connected together intermediate their extremities, a post to which one end of the legs are pivotally connected, va block slidable upon the post and to which the seat supporting bars are pivotally connected at their normal lower extremities, a nut threaded upon the post adapted to engage with said block and forming a stop to the downward movement of the block upon the post, and a seat connected with the upper extremities of the said seat supporting bars, the upper extremities of said seat supporting bars adapted to be moved outwardly on the pivots of said seat supporting bars by the upward movement of said nut for placing the seat in a condition of tautness.

2. A device of the class described, comprising legs and seat supporting bars pivot-` ally connected together intermediate their extremities, a post to the upper extremity of which the normal u per extremities of the legs are pivoted, a b ock movable upon said post and to which the normal lower extremities of the seat supporting bars are pivotally connected, a seat adapted to be supported upon the upper extremities of said seat supporting bars, and means movable upon said post below the planeof said block independentl of the latter adapted to actuate said bloc upwardly on said post and cause the upper extremitles of said seat supporting bars to move outwardly on their pivots and place said seat in a condition of tautness, said means acting as a stop to prevent downward movement of said block upon said post and thereby retaining said seat in its condition of tautness.

3. A device of the class described, comprising legs and seat supporting vbars pivotally connected together intermediate their extremities, a post to which the normal up per extremities of the legs are pivotally connected, a block slidable upon the post below the pivotal points of the normal upper extremities of the legs and to which the normal lower extremities of the seat supporting bars are connected, a member movable upon said post and engageable with said block to cause said block to move upwardly on the post and extend the upper extremities of the seat supporting bars, a fabric seat arranged to be supported upon said seat supporting bars and laced in a condition of tautness by means o said member, and metallic parts connected with said seatand having hooks adapted to be engaged by the upper extremities of said seat supporting bars, the fabric Seat having a margin depending over said hooks and the upper extremities of seat supporting bars.

In testimony whereof I affix my signature in the presence of two witnesses.
