FOLDING STOOL. V i

To all-whom it may concern:

Be it known that 1, CHARLES ERIOKSON, a

citizen of the United States, residing at 1 Brooklyn, in the county of Kings and State of New York, have invented a new and useful'Folding Stool, of which the following is a specification. l

" This invention relates to folding campstools, and has for its object to provide an inexpensive, durable, and efficient stoolof this character in which the parts thereof sha'llbe constructed and combined in such a manner .as toper'mit the sameto be distended and held against collapsing when in use and which may be readily closed or folded into a small compass for transportation or shipment.

A further objectof the invention is to provide novel means for holding the seat-sup porting" arms in "extended position, said means also serving to regulate the tension of the flexible seat.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated 1n the accompanying drawings, and pointed out in the claims hereto ap ended, 1t being understood that various 0 anges in form, proportions, and minor details of construction may be resorted'to without departing from the principle or sacrificing any'of the advantages ofthis invention.

In the accompanying drawings,forming a part of this specification, Figure 1 is a view in elevation, partly in section, the intermediate'portion of the standard being broken away, a section of that portion of the stool below the median line or broken-away portion of the standard being taken at right angles to the seat, and that portion above the median line being taken diagonally thereto.

Fig. 2 is a detail view, in side elevation, 'exhibiting the parts as they appear when folded for transportation. Fig. 3 is a to plan view Specification of Letters Patent.

responding parts in all. the figures of the drawings' Referring to the drawings, 5 designates .the Y 7 standard, which is preferably made of'a single length of metallic tubing, the opposite ends of which are reduced, as indicated at 6 for the reception of rings or sleeves 7. and 8, the former being rigidly secured to the stand.

ard, while the latter is made removable for 1 iii-M v I the purpose hereinafter described. The

rings or sleeves 7 and 8' are each provided with a series of pairs of radial ears 9 and 10, 7 there being in this instance four pairs corresponding to thenumb er of seat-supporting arms and legs employed. Pivoted between the ears 10, as indicated at 11, are suplport- 1 ing-legs 12, the same being substantial y'U- shapedin cross-section and having their piv-- oted ends passing through vertical slots in end of the standard, whereby when a down pressure is exerted on the seat said legs will securely grip the standard? The outer end of each leg carries a pivoted foot, comprising a'plate 13, having an .ear 14', formed integral therewith, the latter beingdisposed between 7 the sides of the legs and combined therewith by a rivet 15. By having-thefoot pivotally connected with the leg the same maybe thus be out of the way when the stool is 001- lapsed for the purpose of transportation, and,- further, by having the foot so connected to the leg it will automatically adjust itself to the. surface upon which it is resting, and

between the ears of the sleeve 7, as by rivets 16, are seat-supportingarms 18, which are also preferably U shaped in cross section and have their outer ends provided with slots 5 i or recesses 19, extending diagonally to 'the length of the arms, as shown.

Combined with the arms -18'is a seat 20, made of suitable-material, preferably canvas, the ends of which are provided at the corners to coverthe terminals of the a1'rns,'and thus render the use of the stool more comfortable. Secured to each of the four corners of the seat on that side which will be the under one in use isa plate 22,- which is secured to the l seat'by rivets 23, said plates being provided with intermediate loops 24, which engage links 25, that interlock with the terminal slots 3 19 of the supporting-arms, as clearly shown IOO with downturned extensions 21, which serve in Fig. 1 of the drawings. Pivoted to an in-.

32 for engagement with the correspondinglythreaded portion 33 of the standard 5. The adjusting-sleeve 31 is formed with an enlarged head 34, defining an annular shoulder 35, adapted to engage an inwardly-extending flange 36 on the collar 29, so that by adjusting said sleeve vertically the tension of the' seat may be regulated at will.

It will be observed that whena downward pressure is exerted on the seatas, for instance, when the latter is occupiedth flange 36 will be forced into engagement with the shoulder 35, thereby effectually preventing collapse of the supporting-arms, and that -when the sleeve 31 is moved in the direction of the supporting-feet a downward pull will be exerted on the arms 18 through the medium of the rods 27, thereby taking up any slack in the flexible seat. It will thus be seen that the adjusting-sleeve and sliding collar form a means both for adjusting the tension of the seat and also for holding the supporting-arms in extended position.

In folding the stool for transportation or shipment the lower ring carrying the supporting-legs is first removed to permit said legs to be folded upwardly to the position shown in Fig. 2, after which the collar 29 is moved toward the lower end of the standard, which causes the rods 27 to seat between the side members of the supporting arms and the latter to lie substantially parallel with the standard. The ring carrying the supportingfeet is then slipped over the reduced end of the standard, with the pivoted ends thereof engaging the spaces between the ears of the upper ring 7, the several parts when this operation is completed being folded or assembled substantially as shown in Fig. 2 of the drawmgs.

In Fig. 7 of the drawings there is illustrated a modified form of the invention in which the upper and lower rings are similar in construction with the exception that the lower ri 8 is provided with right and left hand threads 37, adapted to engage corresponding threads on the reduced end 38 of the standard. In this form of the device in order to collapse the stool the legs are folded inwardly and the rings 8 removed and replaced on the standard in inverted position, which causes the legs to lie substantially parallel with the standard, as before stated. In this form the upper ring will also be threaded for engagement with the adjacent end of the standard, the threads on the upper ring and the contiguous reduced portion of the standard being of the same pitch throughout their lengths.

From the foregoing description it will be seen that there is produced an extremely simple, durable, and convenient device admirably adapted for the attainment of the ends in view.

Having thus described the invention, what is claimed is I 1. A camp-stool comprising a standard, arms pivoted to the standard, a seat carried by the arms, a sleeve mounted for vertical movement on the standard, and a collar engaging said sleeve and pivotally connected with the arms.
