Letters Patent No. 70.323, dated October 29, 1867.

IMPROVED FOLDING CHAIR.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, ISAAC N. DANN, ofNew Haven, in the county of New Haven, and State ot Connecticut have invented a new Improvement in Folding Chairs; and I do hereby declare the following, lwhen taken in connection with the accompanying drawings, and the letters of reference marked thereon, to' be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in

Figure 1, a side view, and in Figures 2 and 3 diagrams, illustrating the manner of folding thc chair.

This invention relates to an improvement in that class of folding chairs which have the legs crossed, and in which an inflexible seat isemployed, and consists'in the peculiar arrangement of the several jointsrelatively to each other, whereby the rigid or inflexible seat is pivoted to the parts so as not to interfere with'the folding.

To enable others to construct my improvement, I will proceed to describe the same, as illustrated in the accompanying drawings.

A is a seat, formed of any intlexiblematerial, 'as wood or iron, or of a rigid frame lled with cane or other suitable material, is pivoted to the rear legs B at C, so as to turn freely thereon, and to the back I) at E, a connection being formed from the back to the seat, as denoted, in figs. 2 and 3,V so as to bring the pivot point of" attachment a little above the seat.- The forward leg F crosses the rear leg B, .and is pivoted thereto at G, and to the back D at I-I, a. point above'the point E, by which the seat is pivoted to the back.

To fold the chair, turn the back forward, as denoted in fig. 2, which raises the rear edge of the seat, the back turhing upon the pivot H, and the seat upon the pivot C. The folding is continued until the two legs pass each other into the position seen in `fig. 3, in which position the chair is folded into the smallest possible compass. And to unfold the chair, simply reverse the operation, repassing the legs and raising the back. When 'set up the backis supported by a bearing in its lower end against the front legs, or the bearing may be xed to the seat.

The same reslt may be accomplished by making the joints at H detachable from the back, and permit the legs to fold independent of the back, but practically Ifind the arrangement first described to be the better plan. Having therefore thus fully described my invention, what I claim as new and useful, anddesire to securel by Letters Patent, is-

The combination of the,inexible or rigid seat Awith the cross-legs F and B and back D, when the joints o'f the several parts are arranged relatively to each other in tlie manner as herein set forth.
