SPECIFICATION forming part of Letters Patent No. 361,527, dated April 19, 188 7.

Application filed November 12, 1886. Serial No. 219,695.

To (ZZZ whom it may concern.-

Be it known that LGABRIEL M.KAZANJIAN, of Bcloit, in the county of Rock and State of Wisconsin,have invented certain new and useful Improvements in Folding Pocket-Stools; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in folding pocket-stools.

The object is to provide a light, convenient, and inexpensive stool, which may be closed to occupy a small space when not in use.

A further object is to provide a stool which shall be effective in use, and one which may be quickly opened or closed.

With these ends in View my invention consists in certain novel features of construction and combinations of parts, as will be hereinafter fully described, and pointed out in the claims.

In the accompanying drawings, Figure l is a view in perspective of my improved stool. Fig. 2 is a view of the several parts partially -in closed adjustment. Fig. 3 is a modification.

A represents a post or standard forming the main support of the stool. This standard is screw-threaded at its upper end, a, and a short distance below the said end a rounded enlargement or boss,b, is rigidly secured to or formed integral with the standard, acting as a supporting-shoulder upon which the seat-frame of the stool rests when set up.

The standard A terminates at its lower end in a triangular yoke, c, the ends of which are upwardly curved and provided each with a slot, 01, preferably oval in form. To insure strength, and at the same time lightness, the standard A is fittingly constructed of hollow steel or other metal.

A sliding collar, 13, is loosely mounted on the standard A, and confined in its motions between the boss I) and the yoke 0. Projecting laterally from the lower portion of this sliding collar B are the bifurcated lugs or jaws 6, sufficient in number to correspond with the supporting-legs O, the upper ends of which are pivoted therein.

The legs 0 maybe of any desirable form and material, the principal objects sought being (No model.)

lightness, strength, and beauty, though a very desirable construction is such as that shown' in the drawings, in which the legs are oblong in section,somewhatextended at their pivoted ends 9 and tapering toward the feetf, the latter being inwardly turned,broad and flattened on their lower faces to form an ample bearing surface upon which to rest.

It will be observed that the legs extend through the slots d in the triangular yoke c, the latter serving to spread or confine the legs 0, respectively, as the collarB is slid down or up. When the collar B is elevated to its full extent, the feet fare drawn close to the yoke c and thelegsOtoward thestandard A. When the collar B is seated at pointhof the concave surface of the yoke c, the legs are extended to their utmost, where they are securely locked by the upwardly-turned ends of the yoke as long as any weight is on the stool, or until the sliding collar Bis again elevated.

A detachable cap, D, is'adapted to be loosely mounted on the post or standard A, over the boss Z), and a nut,d, prevents its displacement. This cap D is provided with the upwardlyprojecting sockets g, which correspond in number with the inwardly-extending braces F of the seat-frame K, the lower ends of which rest in these sockets when the seat is in use. The seat-frame K consists, preferably, of a pair of bars, G, upon which the material E, forming the seat, is stretched, and to the ends of these bars G the braces F are pivoted,so as to enable them to be folded when the seat-frame is detached from the cap D. In folding the stool, the braces F are simply removed from the cap D, the latter being left in its position. As shown in the modification, the construction of these braces F may be slightly varied. In this construction, instead of the free or adjust able ends of the braces F being formed alike, three of them preferably terminate in loops t, adapted to slide successively over the end of the standard A and rest 011 the boss 2), and the fourth in a locking-nut, 7c, screw-threaded inside and provided with three open slots or recesses,l, m, and n, which are successively deeper longitudinally, to allow thelocking-nut 7a to fit over the ends of the other three braces and be screwed down tight thereon. When it is desired to fold the seat, the locking-nut k is unscrewed, the three loops 4' are slid off the standard, and the bars G, braces F, and seat E are folded together.

It is evident that slight changes might be resorted toin the form and arrangement of the several parts described without departing from the sirit and scope of my invention,henoe I do not wish to limit myself to the particular construction herein set forth.

I am aware that it is old in folding campstools to pivotally secure legs to the lower end of the standard, the said legs adapted to be opened or spread apart by means of a sliding sleeve mounted on the standard, and hence I make no claim to such a construction.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a folding stool, the combination, with a supporting-standard and a slotted yoke located at the lower end of the said standard, of a sliding collar, legs pivoted to the collar and projecting through the slots of said yoke, the latter being adapted to guide the legs outwardly or inwardly, respectively, as the sliding collar is depressed or elevated, substantially as set forth.

2. In a folding stool, the combination, with a main supporting-standard and top resting thereon, of a triangular slotted yoke secured to the standard, the ends of said yoke extending laterally and upwardly, a sliding collar loosely mounted on the standard above the yoke and legs pivoted to said collar and pass ing through the slots in the yoke, substantially as described.

3. In a folding stool, the combination, with a main standard, screw-threaded on the upper end, provided near this end with a supporting-shoulder, the said standard being suitably supported on a set of adjustable legs, of a detachable seat-frame consisting, essentially, of a set of upwardly and outwardly extending braces, cross-bars pivoted thereto, and a seat stretched across the bars, the said braces adapted to rest on the standard, substantially as set forth.

In testimony whereof I have signed this specificationin the presence'of two subscribing witnesses.

GABRIEL M. KAZANJIAN.
