I To wZZ whom it may concern.-

. Be it known that I, WILLIAM A. BRADLEY, a citizen of the United States, and a resident of Chesterton, in the county of Porter and State of Indiana, (my post-office address being Chesterton, Indiana,) have invented new and useful Improvements in Folding Chairs, which improvements are fully set forth in the following specification, reference being had to the accompanying drawings.

The object of my invention is to roduce a folding chair which can readily be olded toso constructed that the process gether in two directions, so that the same when folded will occupy a very small space and when open will be a firm strong chair and of folding and Opening the same is easily and quickly ac- I complished.

Figure 1 is a perspective view of the chair opened. Fig. 2 is a rear view of the chair partly, folded; Fig. 3 is a corresponding 1 view showing the chair completely folded,

and Fig. 4 is a vertical sectiona the center of Fig. -1.

Similar letters refer to the same or similar parts throughout the several views.

A A in all the figures are two rigid bars of wood or metal, which are the principal part of the framework of the chair.

B B in all the figures are two rigid bars, similar to A A, but shorter, and attached to A A by pivoted joints at O C.

View through D D are seat-bars and are similar to A A and B B and have one end attached to A A by pivoted joints E E and are'placed at a convenient height for sitting and are also supported by the ends of B B, upon which they rest.

A A are. fastened together and are kept parallel to each other by means of curved slotted'braces F F, which are pivoted together near the middle points at G G. and

.have their upper ends attached to A A by pivoted joints H H and their lower ends slotted and attached to AA by the pivots I I, which slide freely in the slotsJ J.

K L are two members of a folding brace.

which are pivoted together at M and also pivoted toA'A by the pivots I I, N being a" notch in K, which hooks over a stud O onL and when so hooked or locked makes the cross-braces F'F firm and rigid.

F F and control-B B in precisely the same manner as F F controls A A.

QR' are the members of a folding brace precisely like K L and having a notch in Q at S, locking over a stud T in R and folding on U.

The folding braces K L and Q R work in unison and govern the curved slotted braces F F and PP and when folded on their pivots M and U allow A A and-B B to fold together tightly, as shown. in Fig. 3, and when. said folding braces are 0 on and extended and the notches N and are locked or hooked over the studs 0 and T the framework of the chair is open and forms a firm and solid chair,

The seat and back of the chair are made of canvas, leather, or any material. I v To fold the chair, lift the braces K L and Q R, which fold on their pivots M and U and other strong pliable I press A A and B B together, and to fold in the other direction lift the seat-bars D D till they are parallel with A A, when B B, being attached thereto by the pins X X', working in slots Y Y and moving in unison with D D, will also be parallel to AA, when the chairwill be folded tightly together, as shown in Fig. 3.

My invention is an improvement on the style or kind of folding chairs in which two wood or'metal bars form the principal art of'the framework of the back of the'clifair, and the lower part of said bars or posts form two of the legs of the said chair, and two other similar but shorter bars attached'to said back bars or posts by pivoted joints form the support for the seat and also the other twolegs of the chair.

I claim as my invention In a folding chair, the combination of two sets of cross pivoted legs, each set of legs consisting of parallel members, a pair of cross pivoted braces connecting the parallel members of each set, each member of said crossbraces pivotally connected to one of the parotall engagement with each other at the other 611 WILLIAM A BRADLEY.
