Specification forming part of Letters Patent No. 40,208, dated October 6, 1863.

To all whom it may concern:

Be it known that I, OLIVER D. ABBOTT, of Chelsea, in the county of Sufi'olk and State of Massachusetts, have invented an Improved Portable Stool or Chair; and I do hereby declare that the following, taken in connection with the drawings which accompany and form part of this specification, is a description of my invention sufficient to enable those skilled in the art to practice it.

This invention consists in the application of a folding back to a portable or folding stool, sometimes called a camp-stool, converting such a stool into a chair.

The drawings represent a stool embodying my improvement, Figure 1 showing a top view or plan ofthe same, and Fig. 2 a side elevation of it.

A A A A denote four legs or posts, one of which is jointed at its center to each side ofa quadrangular band or strap, B, the legs turning on the sides of said strap, so that when they are spread open and the stool stands erect they assume the position seen in Fig. 2. To the top ends of these four legs the seat 0, made of cloth or other suitable material, is applied, one corner of the seat being fastened to the top of each post.

To the top of each rear leg, A A", one end ofv a movable arm, I), is jointed by a pin or rivet a, each arm being so jointed as to be capable of swinging diagonally in a plane parallel to that in which the arm to which it is jointed moves. \Vhen the stool is erect, and the back is to be used, the arms D stand vertical, or nearly vertical, as seen in Fig. 2. A cross-band or back-rest, E, connects the tops of the arms D, and two side bands, F F, hold them in position, or keep the back from swinging over when the person sitting on the stool leans against the band E, the side bands for this purpose extending from the tops of the front legs, A A, to the tops of the adjacent arms D. hen the stool is in use, it will be observed that the weight of the sitter has a tendency to spread apart the tops of the legs and thereby draws taut the band E, and keeps it from sagging. When the stool is to be closed or folded up, the ends of the legs are drawn together, and as their tops approach each other, the relaxation of the side bands, F, allows the armsD to be turned over backward and to be brought down, so as to lie against the sides of the legs A A to which they are jointed, as seen by dotted lines in Fig. 2, the whole stool, when so folded, assuming the position seen in Fig. 3, which denotes a view of the stool when so folded. To open the stool, I generally hang the arms somewhat loosely to the legs, so that by a quick outward or upward movement given to the legs as they are spread, the arms are thrown up into proper position. Vhen it is not wished to use the back, the arms may be allowed to rest against the legs, as seen by dotted lines in Fig. 2, or to hang vertically-down from the tops of the legs, the opening of the stool not interfering with or being interferred with by these positions of the arms. By this construction of the stool, and adaptation of the arms and bands to obtain a support for the back, I obtain a light, portable, and easily adjusted folding stool and chair, and one in which all the parts lie in close juxtaposition when the stool is folded, making a compact arrangement of members, as will be readily understood by inspeetion of Fig. 3. I joint the legs to the band or strap on which they turn, and the arms to the legs by strong and durable rivets, so that there is no danger of their loosening, unt'astening, or becoming worn, excepting from long and continued usage.

In camps, on shipboard, when traveling, and at various other times, these portable stools or chairs are found very convenient and useful, and such an article, having a support for the back, has long been a desideratum which my stool will be found to supply.

I claim- Combining folding arms (which in connection with bands form a back) with the folding legs of a portable stool, substantially in the manner and for the purpose as above set forth.
