N.PEIERS. PHOTO-LITHDGNAPNER. WASHINGTON u c DAVID N. SELLEG, OF NEVVBURG, NEW YORK.

FOLDING CHAIR.

SPECIFICATION forming part of Letters Patent No. 233,880, dated November 2, 1880.

Application filed June 2, 1880.

To all whom it may concern Be it known that I, DAVID N. SELLEG, a citizen of the United States, residing at Newbnrg, in the county of Orange and State of NewYork, have invented certain new and useful Improvements in Folding Chairs; 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, reference being bad to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to an improvement in folding chairs, the object being to simplify their construction and avoid certain defects existing in those now commonly used.

To secure this end I provide the side pieces of the seat with a tenon at their rear ends, which, when the seat is opened, enters a mortise in the back posts, the seat being also connected by links to the back posts and pivoted at each side to the front legs, which are extended upward, so as to form arms, and con nected with the back by pivotal joints. The posts of the back extend down, and are connected at their lower ends to the rear legs by a pivot, which has, also, a sliding movement in a slot formed in the legs, the upper end of said rear legs being connected directly to the arm by a pivotaljoint, or the connection may be made by means of a short link or lug, if desired; and the invention consists in the construction and arrangement of these several parts, as will be hereinafter fully described, and then specifically pointed out in the claim.

In the drawings, Figure l is a side elevation of the chair open. Fig. 2 is a vertical section of the same and the connecting rounds and bars. Fig. 3 is a side View of the chair folded. Fig. at is a sectional view of parts similar to those shown in Fig. 2, but folded.

A represents the front legs of the chair, extending upward, so as to form a brace arm or support to an arm-rest, and pivoted at its upper end to the back posts, B. These posts (Model) are connected by the slats or bars a and round a, the latter being used as a support for the rear of the flexible seat when such a seat is used. These posts are also provided with mortises at 1), into which a tenon on the side pieces, 0, of the seat enter when the chair is open. These side pieces are connected at their front ends by a bar, b, which carries the front end of the seat.

A further connection is made between the back posts and the side pieces of the seatframe by means of the links 0, which are pivotally attached at their ends to the frame and back posts, allowing perfect freedom of movement to the seat in folding up, but holding its tenons firmly in the mortises of the posts when opened.

Attached to the upper portion or arms of the front legs, A, by links 0, or ordinary pivotal joints, are the back legs, D, which are provided near their mid-length with slots at, in which the pivot-pins 0, attached to the lower end of the back posts, slide when the chair is either folded or opened.

It will be apparent that the chair, constructed as above described, may be readily folded, as shown in Figs. 3 and 4, into a compact form, while the seat may be either a full frame or flexible, as desired.

It will also be seen that the slots d for pivotpins 6, which connect the back posts with the legs, may be formed in the back posts and the pivot-pin attached to the leg without changing the action of the parts or departing from the spirit of my invention.

I am aware that many folding chairs have been constructed having a general appearance similar to mine 5 butI know of none constructed seat-frame (3, back posts, B, provided with joint operation in the manner shown and (le mortises for the reception of tenons on the scribed. 10 seat-frame, connecting links 0, front legs, A, In testimony WhereofIaffiX my signaturein pivoted to the seat and posts, and the back presence of two Witnesses.
