SPECIFICATION forming part of Letters Patent No. 587,391, dated August 3, 1897.

Application filed December 10,1896. Serial No. 615,120. (No model.)

To all whom it may concern.-

Be it known that I, NATHANIEL O. GANDY, a citizen of the United States, residing at Chester, in the county of Delaware and State of Pennsylvania, have invented certain new and useful Improvements in Stools; and I do 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 improvements in folding stools, and its novelty and many advantages will be fully understood from the following description and claims when taken in connection with the annexed drawings, in Which- Figure 1 is a perspective view of the stool ready for use. Fig. 2 is a similar view of a modified construction of stool. Fig. 3 is a transverse section taken through the legs of the stool at the point where they are connected. Fig. 4 is a detail section taken in the plane indicated by the line x a; of Fig. 3 and illustrating the elongated nuts.

Referring by letter to the said drawings, J indicates my improved foldable stool. It is highly desirable to have the stool capable of folding compactly, and to this end I form the three legs j of the stool of light metal tubing and connect the same at or adjacent to their middle by the bolt 75, (see Fig. 3,) which has branches Z extending into the legs through apertures m in them, and the elongated nuts n, which are secured upon the threaded branchesZ within the tubes, as shown. In assembling these parts each tubular leg j is placed on a branch l of the bolt 70, and a not w is introduced into the leg and held by a long pair of pincers or other suitable means, so that its threaded aperture rests in a position to receive the threaded branch of the bolt..

The leg is then turned, together with the nut, on the branch Z of the bolt until the nut is screwed on the said branch I a sufficient distance. This manner of connecting the tubular legs permits of the same being spread, as shown in Fig. 1, to enable the stool to stand alone, and also permits of the said tubes being brought close together and parallel to each other. The elongated nuts n are preferable, because it is necessary in order to screw them on or off the threaded branches of the connecting-bolt to turn the legs j, which of course reduces the liability of casual disconnection of the legs to a minimum.

The stool J is provided with a triangularshaped seat K, which is preferably formed of network, as shown, because of the lightness of the same and the fact that it is adapted to fold compactly and hang from the ends of the tubular legs j. This seat K is shown as connected to eyes p upon the upper ends of the legs j, but it is obvious that it may be connected to said legs in any other suitable manner.

As a modification of my improved stool I would make two of the legs considerably longer than the third leg, as shown in Fig. 2, as by this provision the seat K, being connected to the upper ends of all of the legs, is adapted to support the back of the person seated upon the stool, as will be readily appreciated by reference to Fig. 2.

Having described my invention, what I claim is 1. A foldable stool for the purpose described comprising the tubular legs having the apertures m, at corresponding intermediate points of their lengths, a seat of flexible material connected to the upper ends of the legs, the bolt formed in one piece and arranged between the legs and having branches extending through the apertures m, into the legs, and devices arranged in the legs and detachably connected with the branches of the bolt and serving to secure the legs on said branches, substantially as specified.

2. A foldable stool for the purpose described, comprising the tubular legs having the apertures m, at corresponding intermediate points of their length, a seat of flexible material connected to the upper ends of the legs, the bolt 70, arranged between the legs and having the threaded branches Z, extending through the apertures m, into said legs, and the elongated nuts arranged in the legs and mounted on the threaded branches Z, of the bolt, substantially as specified.

8. A foldable stool for the purpose described comprising two tubular legs of corresponding length having the apertures m, at equidistant points from their lower ends, a third tubular leg, shorter than the other two, having an aperture m, at a correspond- ICO at equidistant points from the lower ends of the legs, and the combined seat and back of flexible material and triangular shape in outline connected at its corners to the upper ends of the legs and occupying the space between said upper ends, substantially as specified.

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