FOLDING CHAIR.

SPECIFICATION forming part of Letters Patent No. 479,35 5, dated July 19, 1892.

Application filed March 1890. Serial No. 342,801- (No model.)

To all whom it may concern.-

Be it known that I, EDWARD E. ELDRIDGE, a citizen of the United States, residing at North East, in the county of Erie and State of Penn- 5 sylvania, haveinvented 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 to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, forming part of this specification.

My invention consists in the improvements in folding chairs hereinafter set forth and explained, and illustrated in the accompanying drawings, in which- Figure 1 is a vertical section of my improved 2o folding chair. Fig. 2 is a like section of the chair when folded up. Fig. 3 is a detail view of a portion of same.

In the construction of my improved folding chair shown the legs A form the bearing for the rear end of the seat-frame B and the legs O the bearing for the front end thereof, these legs A and 0 being pivoted together at d. The legs A also extend upward above the rear end of the seat-frame B, where they are connected together by framework D, secured therein, which secures the legs on each side of the chair together and also forms the chairback. The upper ends of the legs 0 are also secured together by means of a, transverse round E, so as to retain the legs 0 on each side of the chair firmly together.

To the under side of the rear of the chairframe is secured a cross-piece F, preferably of about the same thickness as the round E, and to ends of the cross-piece F are secured stud-pins f, which extend into a slot G in the inside face of each leg A, so as to support'the rear end of the seat 13. These slots Gextend upward in the legs A sufficiently to permit the folding up of the chair, as shown in Fig. 2.

To the under side of the cross-piece F, at each side of the seat-frame B, the rear ends of guide-Wires H are secured, which wires extend forward parallel with the under surfaces of the sides b of the seat-frame B to the round E, when they are bent upward and are secured to the under side Z) of the seat-frame B,

so as to form a support for the round E in the upper ends of the legs 0 when the chair is in use, and they also operate as guides for 5 the round E when the chair is being folded up. Connected at one end to the under side of the cross-piece F and extending forwardly and downwardly from the same is an arm I,

which is provided at its free end with an angular branch J, as illustrated, adapted to engage the upper portion of one of the legs O when the chair is being unfolded and throw said legs forwardly into their proper position,

as will be presently described. 6 5

In operation when the chair is in its open or operative position and it is desired to fold the same the inner end of the seat-frameB is raised, when the pins f will travel upwardly in the slots G and the free or outer end of the said seat-frame will approach the legs A.

. To complete the folding of the chair, it is then necessary to swing the legs 0 on their pivots d toward the rear of the chair, thus causing the cross-bar E to travel rearward in the guides H and allowing the free or outer end of the seat-frame to drop to a vertical position against the folded legs;

When the chair is folded, as shown in Fig. 2 of the drawings, and it is desired to open the same, the free or outer end of the seatframe B is pulled away from the legs A, (the pins f acting momentarily as pivots,) when the angularbranch J of the arm I will engage the edge of one of the legs 0 and will push the upper ends of said legs away from the legs A and will cause the round E to move toward the free end of the seat-frame. As the free end of the seat-frame B is pulled away from the legs A, the pins f will move downwardly in the slots G of said legs, and the branch J of the arm I will bear against one of the legs 0 until said legs and the seat-frame B reach the position shown in Fig. l of the drawings.

Having thus fully described my invention, 5 so as to enable others to make and use the same, what I claim as new, and desire to secure by Letters Patent of the United States, 1s

In a folding chair, substantially as described, the combination, with the legs A, extending above the seat-frame and having the longitudinal slots G in their inner sides, of the seat having the cross-piece F adjacent to its rear transverse edge, the pins connected to the said cross-piece and sliding in the slots G of the legs A, the guides H, secured to the under side of the seat and to the cross-piece F, the legs 0, pivotally connected to the legs A, the transverse round E, connecting the upper ends of the legs Gand sliding between the guides H and the lower side of the seat,

and the arm I, connected to the cross-piece F and having an angular branch adapted to engage with the upper portion of one of the legs C when the chair is being unfolded, substantially as and for the purpose set forth.

In testimony whereof Iatfix my signature in presence of two witnesses.

EDWARD E. ELDRID GE.
