FOLDING CHAIR.

SPECIFICATION forming part of Letters Patent No. 529,6 45, dated November 20,1 894.

Application filed February 7, 1894. Serial No. 499658. (No model.)

To all whom it may concern:

Be it known that 1, WALTER N. CLARK, of Warren, in the county of Trumbull and State of Ohio, have invented certain new and useful Improvements in Folding Chairs; and I do hereby declarethe 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.

This invention contemplates certain new and useful improvements in folding chairs and it has for its object the production of a new and improved chair of this nature which shall possess advantages in point of simplicity, durability and general efficiency and which when closed or folded will be compact and occupy but minimum space.

The invention comprisesthe novel features of construction, and also the detail combination and arrangement of parts substantially as hereinafter fully set forth and particularly pointed out in the claim.

In the accompanying drawings: Figure 1 is a view in side elevation of my improved chair opened or extended. Fig. 2 is a view in perspective showing the same closed.

Referring to the drawings, A designates the back; a, the fore-legs; a, the rear legs and a the seat. Each side-bar of the back and one fore-leg are made or sawed from one continuous piece of board b having an upper shoulder or offset b at the inner end of which,

is a curved recess b and beneath the latter is a second curved recess b and a reduced The side-bars of the back are conneoted by cross-rods b and the fore-legs by similarrods h The rear legs a, consist each of a single board having a knuckle like end O and said legs are connected by cross-rods D, said ends fitting in the lower curved recesses b The sides of the seat-section a have inner knuckle-like ends 01 which fit in the upper recesses 12 E designates a plate attached to the outer sides of board 5 and having upper and lower projecting ends to which the seat a and rear legs a are pivotally united by bolts e, e', respectively. In the outer edge of each rear leg is a notch or groove e which is designed to engage the lower edge b of the back. The seat when lowered rests upon the shoulder or ofiset b and the back of the chair is held at the proper inclination by the lower reduced edges b entering the notches e of the rear legs. When closed the seat folds up against the back and the rear legs toward the fore legs. I

The advantages of my invention are apparent. It will be seen that by making the back and fore-legs in continuous pieces the strength thereof is greatly enhanced and by pivoting the seat and rear-legs as shown and described the same can be compactly closed or folded and when the parts are extended they will be held in proper fixed relation.

A folding chair having the foregoing characteristics is extremely simple and inexpensive and capable of being readily and easily constructed.

I claim as my invention A folding chair having its back and fore legs formed from continuous boards having lower recesses and reduced edges, and upper recesses and offsets or shoulders, a pivoted WALTER N. CLARK.
