CHAIR.

Specification of Letters Patent.

Patented Jan. 19, 1915.

Application filed June 19, 1913. Serial No. 774,605.

To all whom it may concern:

Be it known that I, WILLIAM F. McDow- ELL, a citizen of the United States, residing at Gardner, in the county of Worcester and State of Massachusetts, have invented a new and useful Chair, of which the following is a specification.

This invention relates to chairs, and particularly to that class of chairs having a rigid wooden frame construction.

The object of the present invention is to improve the construction of such articles and to simplify and cheapen the manufacture thereof.

The features of the invention relate to certain combinations and arrangements of parts hereinafter described and particularly pointed out in the appended claim.

A preferred form of the invention is disclosed in the drawings, in which-- Figure 1 is a perspective view of a chair embodying my improvements; Fig. 2 is a detail of the upper end of one of the back posts; Fig. 3 is a detail of one end of the upper back rail; Fig. 4 is a sectional View taken substantially on the line 44 in Fig. 1 and showing the connection between the back post and the upper back rail; Fig. 5 is a sectional view taken on the line 55 in Fig. 3.

Referring to Fig. 1, it will be seen that the chair showing a preferred form of my invention embodies the usual back posts 10 and the upper back rail secured to the front edges of said posts and extending longitudinally beyond said posts.

One important feature of my invention relates to an improved method of securing the upper back rail to the back posts.

As shown in Fig. 2, the back post 10 is provided on its front edge near the upper end with a flanged portion 11 formed by removing a portion of the material from the opposite sides of the post to form-undercut recesses 12. The front edge of the post is also provided with a transverse shoulder 13, the object of which will be hereinafter explained. The flanged portion 11 terminates somewhat below the end of the post 10.

Referring to Figs. 3 and 5, the upper back rail let is provided with an undercut recess 15 corresponding in dimensions to the undercut flanged portion 11 of a post 10. This recess in the back rail may be conveniently formed at a single operation by the use of a T-cutter upon any ordinary form of molding machine. The parts thus formed are assembled as shown in Figs. 1 and 4, the back rail being forced downwardly as by blows from a hammer until the lower edge thereof is seated firmly on the shoulder 13. This shoulder acts to definitely position the parts 10 and let relatively to each other. The flanged portion 11 may be coated with glue if desired before the parts are assembled.

Another feature of my invention relates to an improved method of bracing the seat rails and of securing the seat thereto. This construction is particularly adapted to that class of chairs provided with a removable or slip seat, but is not necessarily confined thereto, and may be used to advantage in chairs provided with a permanently attached seat.

The utility of my invention will be clear from the above description, particular attention being called to the fact that I secure a firm and rigid construction and avoid the use of screws or other similar fastening means.

It will be evident that many modifications of my invention may be made by those skilled in the art, and I do not 'wish'to be limited to the particular form disclosed in the drawings, but

What I claim is 2- I A chair having in combination a pair of back posts and an upper back rail, each post being cut away at the end near its upper front corner and having a groove extending downwardly from said cut away portion on each side of the post and separated from the front edge by a portion forming a flange, said rail extending longitudinally beyond the post and having a grooved recess extend.- ing from the lower edge of the rail part way across the same on its back side, said flanges and said recesses coacting to secure the parts permanently together and that part of the post behind the cut away portion serving to conceal the upper end of the recess in the rail.

In testimony whereof I have hereunto set my hand, in the presence of two subscribing witnesses.

WILLIAM F. MCDOWELL.

Witnesses:

ALBERT E. FAY, CATHARINE I. HARTNETT.
