Specification of Letters Patent.

Patented Sept. 11, 1917.

Application filed January 12, 1916. Serial No. 71,739.

State of New Jersey, have mvented new and useful Improvements in Stools, of which the following is a specification.

This invention relates to improvements in stools and more particularly to that type of stool primarily adapted for use in stores, lunch rooms and public dwellings.

The primary object of the invention is the provision of a stool of the above stated character providing a novel construction which is simple, inexpensive to manufacture, practical and efficient in use and may be readilyset up or folded as required, and it is to be understood that the several parts constituting the stool are so constructed and assembled as to permit of a quick detachment and assemblage of the parts to warrant the repair or duplication of such to the stool when found necessary.

With the above and other objects in view, the invention consists in the novel features, details of construction and combination of parts which will hereinafter be more fully set forth, illustrated in the accompanying drawings, and pointed out in the appended claims.

Figure 1 is a side elevation of the stool;

Fig. 2 is an enlarged transverse section taken through the seat of the stool and through the means for connecting the legs with such stool;

Fig. 3 is an enlarged section taken through the legs of the stool illustrating the. manner of connection of the sections constituting the legs to one another;

Fi 4 is a side elevation of a stool showing a slightly modified form of means for revolubly supporting the seat of the stool on said legs;

Fig. 5 is an enlarged transverse section taken through the seat of the stool and the connection between the seat and the legs of the stool.

Fig. 6 is a section taken on line 6-6 of Fig. 5.

Fig. 7 is a plan view of the brace.

Referring more specifically to the accompanying drawings, in which like characters of reference refer to corresponding parts in the several views, 5 designates a seat portion of the stool having connected with the under surface thereof an attaching plate 6 by means of fasteners in the form of screws and the like designated by the reference character 7. This plate is provided centrally thereof with denending spaced apertured ears 8. I connect with this attaching plate a means for revolubly supporting the seat and in Figs. 1 to 8 inclusive this means is shown as embodying a sectional casing 9 provided with a series of apertured extensions 10 and 11. This casing when in assembled position is of substantially hollow cylindrical form and is adapted to receive and retain therein a solid circular head portion 12, thereby establishing a ball and socket connection. This ball and socket connection is supported from the under face of the seat portion 5 by a bolt-13 passing through the extension 10 of the casing and through the apertures 14 of the ears while additional bolt members 15 pass through the extensions 11 for retaining the sectional casing together. This casing when in assembled position presents on the lower surface thereof an arcuate slot 16 through which project a series of lugs including an intermediate and end lugs 17 and 18 respectively and each of said lugs is provided with an aperture 19, the said lugs having pivotally connected therewith a support 20 comprising a plurality of legs 21, through the medium of a pivotal pin 22. Each of the legs 21 comprises an upper section 23 and a lower section 24., the upper section 23 being telescopically and slidably mounted within the lower section 24 and each of said sections is preferably constructed of tubular metallic sections. The pivotal pin 22 passes through diametrically disposed apertures 25 formed in the upper end of the upper leg section 23 and the upper leg section is further provided angularly of the apertures 25 with an elongated slot 26, the purpose of such slot being to permit of clearance of the lugs when the legs are swung on the pivotal pin 22 in an outward and supporting position. Housed within the lower tubular leg section 24 is a strong helical spring 27 said spring being welded or the like to the lower end of the uppermost leg section 23 and a thumb bolt 28 passes .through the diametrically disposed apertures 29 of the lowermost leg section and between certain coils of the spring 27, thereby loosely and yieldably connecting the lowermost leg section with the uppermost leg section. It is apparent from the disclosure of the drawing that the lowermost leg section 24 of the support 20 is formed with a plurality of vertically alined apertures 29 whereby the thumb bolt 28 may be readily inserted in any of the apertures inorder to adjust the various heights of the stool to permit of the leg sections of the support being closed Whenit is desired to fold the stoolin compact form.

In Figs. :1 and 5 oi 'the draiving:Llravevillustrated a slightly modified form. of the means for revolubly supporting ;t he seat upon said legs and gin .this particular .invstance the plate (3 is formed integral on,its under faceflwith a hollow tubular,extension ,30 adapted toreceivetherein ahollow cylinembodying, the preferred iormof my invention and Lemploy for holding thelegsoi ,each jfOl'Hl vof invention in supported posi- ,tion, ,a-triangular brace member 36 which ;is slidably mounted upon 7 and in. embraced relation with the {legs ,Whereby the same may ibe readily adjusted upon the spreadingor closing ofthe legs astheoccasion may'so demand.
