FOLDING CHAIR.

SPECIFICATION forming part of Letters Patent No. 44,4,01 1, dated January 6, 1891.

I Application filed July 5, 1890. Serial No. 357,800. (No model.)

To all 1077,0721, it may concern: pivotal devices consisting of a plate and Be it known that I, CHARLES H. ORCUTT, socket-cap, as already described in the applicitizen of the United States, residing at Springcation above referred to.

The rod is conveniently each end with the rear legs A, preferably by guided by a groove in the seat-frame, and means of a dowel and socket I, as shown in passes over the strip H, and is conveniently 10c Fig. 8. The front legs J are preferably se= supported at its rear end bya plate P, secured cured to the front end of the seat-frame by to the seat-frame. The position of the 1ocking parts when the chair is locked in its sitting position is shown in Figs. 3, 6, and 7.

The round E before mentioned is convenient-ly provided with a plate Q, having an opening therein, and screwed or otherwise fastened to the said round or cross-piece, so that when the seat assumes its folded position the rear end of the locking-bar will be pressed inward by said plate and slipped into the socket in the same, and thus lock the chair in its folded position, as shown in Figs. 1, 2, and 5. The rear end of the said bar is preferably rounded or beveled, so as to facilitate the action against the plate Q and strip M when it engages therewith. It will be seen that the spring of the metal of which the bar is formed tends to keep it always pressed outward. Any other means for causing this out-- ward action may be employed as long as the bar is accessible from the front end of the scat.

If desired, I may dispense with the round E and lock the chair in its sitting position only, as before described.

The term spring-rod is used to cover any form of spring-locking means, whether in the form of an integral spring-rod or a rod actu ated by a spring separate therefrom.

- Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a folding chair, the combinatiomwith its back and its seat, the back being provided with an upper cross-piece having a socket and adapted to form a stop for said seat when folded,and also a lowercross-piece having a socket, and the seat being provided with a strengthening cross-piece near its rear end and pivotally connected to the said back, of a spring-actuated locking'bar mountedin said seat and adapted to engage with the sockets in both cross-pieces, respectively, whereby the chair is locked in both its sitting and its folded position.

2. In a folding chair, the combination, with its seat and its back provided with a crosspiece having a socket and adjacent to the rear end of said seat, of a spring locking-bar mounted in said seat so as to be accessible from the front end thereof and normally projecting outward and adapted to automatically enter said socket when the chair is folded,and thus lock it in its folded position.

3. I11 a folding chair, the combinatiomwith its back and its seat, of an upper and alower piece carried by said back adjacent to the rear end of said seat, and a locking device consisting of a sliding member and a fixed member, one member being carried by said seat so as to engage with the other member carried by said upper piece, and also of a duplicate member carried by said lower piece, whereby the chair is locked in both its sitting and its folded position.

4. In a folding chair, the combinatiomwith its seat, its back provided with an upper and a lower pi ce ad jacentto the rear end of the said seat, and bearing or looking plates car ried by said pieces, of a springlocking-bar mountedin said seat so as to be accessible from thefront end thereof and adapted to engage with said bearing or looking plates on the said pieces, respectively, whereby the chair is automatically locked in both its sitting and its folding position andunlocked by manipulating said bar.

5. In afoldingchair, the combination,with its seat and its back provided with a cross piece adjacent to the rear end of the seat, of a spring locking-bar adapted to slide-in and out from the edge of saidseatand accessible from the front end thereof and adapted to engage said cross-piece andlock the chair in its folded position.

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

CHARLES H. ORCUT'J.
