To all t may concern.'

Be it known that I, ARTHUR VVURDAoma l citizen of'the United States, residing at N orniandy,` St. Louis County, Missouri, have invented a certain new and useful Improvement in Chairs, of which the following is a specification, such as will enable others skilled in the art to which itappertains to make and use the saine. l0

My inventionrelates to furniture and consists in an improved chair or rocker construction. v 0

The object of myinvention. 1s to provide a simple economical chair having a yielding back, to provide a chair which may be easily assembled and disassembled for shipping or i storing, and to provide a chair which may be used outdoors as well as indoors without. deterioration due to the weather.

In the accompanying drawings which illustrate my invention- Figure 1- is a side elevation ot my *improved chair, the dot and dashI lines indicating the modification of the chair to produce a rocker. v

.Figure 2 is a rear elevation of thesame.

Figure 3 isa vertical section on line 3-3 of, Figure 2.

Figure 4 is a 4--4 ofFigure 2. Figure 5 is a, rear elevation corres onding to Figure 2 but' showing va. modiie construction.

The chair comprises four straight legs, referably dis osed vertically, the rear legs being indicate at 1 and the front legs at 2. A rear rail 3 connects the/rear legs 1, a front rail 4 connects th'efrontlegs 2, and side rails 5 connect 'a front and a rear leg on each side of the chair, respectively. The chair seat is formed by' one or more boards 6 extending across opposite rails. All of l'the parts mentioned are rectangular in Sha e to facilitate their preparation and assem ly, the legs being gained vnear their upper ends to receive rails and forma better joint. e

Spaced below each rail is "a rung connecting the legs, the rear rung' being indicated at 7, the side rungs at 8 and the front rung A Vat 9.

y My invention consists particularly in the back and its application to the chair. In

the preferred form, the back consists in a single board 10 thin enough to be flexible,

t0 a limited extent, when under pressure horizontal section on lineV from the back of a person sitting upon the chair. The width of the board is preferably the' same as the distance between the rear legs 1 and the board extends down below the seat a substantial distance and is so inclined that itextends between these rear legs and braces them transversely of the chair. The lower end of the board is securedto rear rung 7 by means of bolts 11 and near the chair seat the back is secured toy rear rail 3 by means of bolts 12. The projection of rail 3 to the rear of rung 7 and the still further rearward projection of seat 6 rovides means forinclining the back formingl board as shown.v By-tiglitenvEKO ing bolts 12, board 10 `is drawn against the rear edge ofvseat 6 and the extended bearing ofthe seat' edge and the back forms a pivot about which the` back may bend as indicated in Figure 3 and lessens the likelii hood of splitting of the board under pressure.

piriifi. i

ile I have illustrated the single board 10 as the preferred back construction, similar results will'be` obtained, and ossibl costs` will be lowered, by the use o a bac formed of a plurality of strips, such 'as in- In use, the back described aords a firm dic-ated in Figure 5, in which the strips 13"v are shown connected near their lower end by a cross piece 14 and near their upper end by a cross piece 15. It desired a cross piece 16 may be .provided adjacent to. the'back rail 17 to receive the bolts 18 and distribute thel bolt pressure to the strips 13.

Obviously, the cross piecesv 14,' 15 and' -16 v may be omitted and a bolt provided foreach strip at the rung 19 and at rail 17.

Other modiications of my invention will suggest themselves in the manufacture of my improved chair and I contemplate such variations as are included followingclaims.

I claim:

1. In a chair a seat, front and rear legs supporting said seat, .a rear rail rigidly Qonin the scope of the 4 nected with the rear legs below said seat, a rung connected with Ysaid rear legs in front of the plane of said rail, and an upwardly and rearwardly inclined back member having its lower portion attached to said rung and its intermediate portion attached to said rail.

2. In a chair a seat, front and rear legs supporting said seat, a rear rail rigidly connected with the rear legs below said seat, a rung connected with said rear legs in front of the plane of said rail, and a flexible back a level of said seat to form a yielding back for the chair.

4. In a chair, a seat, a back extending from below said seat to above the level of said seat and consisting in a single substantially straight exible board secured at close intervals near said seat and at a point below said seat and unsecured above said seat so as to bend about the rear edge of the seat as a pivot.

5. In a chair, a seat, spaced rear legs sup` portin said seat, and .a single exible board secure adJacent to said seat, the lower por- `wardly therefrom above said tion of which board extends between and braces said legs and the upper portion of which board projects above the level of said seat and forms a yieldingback for the chair.

6. In a chair, a seat, rear legs, a rail beneath said seat and connecting said lees, a rung below said rail and spaced therelrom and connecting said legs, and a back consisting of a flexible board secured to said rung andto said rail and extending upscat and unsecured above said rail. A

7 In a chair, rear legs, a rung between said legs, a rear rail at the top of said-legs and'projecting rearwardly thereof, a seat above said rail projecting rearwardly thereof, and a flexible back-founding board the lower portion of which is held rigid by being secured to said rung and rail and the upper portion of which is positioned b the rung and rail and the rear edge of Sai seat so as to incline rearwardly above the level of said seat. i

8. In a chair,'rear legs, a rung between said legs and below the tops thereof, a seat projecting rearwardly of said legs, a flexible board secured to said rung extendin upwardly therefrom and forming a bac for the chair,a rear rail at the tops of said legs in front of the rear edge of said seat, and

means drawing said board against the lower edge of said rail and against the rear edge of said seat. l

In testimony whereof I hereunto alix my signature this 12th day of August, 1924.

ARTHUR. WURDACK.`
