Letters Patent No. 100,132, dated February 22, 1870.

IMPROVEMENT IN THE CONSTR'U-'CTION OF CHAIRS.

The Schedule referred` to in these Letters Patent and making part of the same.

To all 'whom it may concern:

- Beit known that I, HARRY H. EVARTS, of Chicago, in the county of Cook, and State of Illinois, have invented a new and useful Improvement in Chairs; and l do hereby declare the following to be a full, clear, and exact description ofthe same, reference being had tothe accompanying drawings and the letters and figures marked thereon, which form a. part of this specification, and in which- Figure 1 represents a bottom view of my improved.

chair; v

Figure 2, a sectional view at the line @looking to lthe left;

Figure 3, a sectional view at the same line, looking to the right; and

Figures 4, 5, 6, and?, top or plan views of the iron brace-scr brackets A, detached from the chair. f

"lhe object of my invention is to `so brace and strengthen a chair at its jointswhere the ,legs are joined to the seat, and where the frame of the seat is joinedl together, that itiwill Vbe strong and durable, and not be constantly falling apart and needing repairs, as is now the case with most chairs. x

The nature of my invention consists inthe combination o'f the chair-legs, the brace or brackets A, and the chair seat, as hereafter more fully described.

To enable those skilled in the art to understand how to manufacture and use my invention, I will proceed to describe the same with particularity. v

'lhe same letters of reference refer to the `corresponding part-s in the different figures.

Chairs are very liable to become loose at the joints, especially when the legs are attached or joined to the seat, and when the seat is made of a frame put together with joints at the corners there is more or less liability of these joints becoming loose, since the legs and posts are attached-to the frame of the seat at the corners, so that all the lateral strain on the chair tends 5 to loosen ,these joints. To strengthen these joints and make them firm and'.

solid, I make metallic brackets or braces, A, of anyv desired shape to fit the leg of the and the un'- If the'chair-'legs are round, as is frequently the case,

andas is shown in iig. 2, the brackets or braces `are made with one concave or circular flange to lit, and if thechair-legs have square corners, as is shown in iig. 3, the brackets are made with corners to flt them.

The ange's ofthe brackets that are fastened to the chair-seat are suiiciently wide, and of a proper shape to receive a screwastening'on each side of the joint -in the corner of thev flame. In this way' the chair-legs are firmly secured to the chair-seat, and the joint-s at the corners of the seat-frame are strengthened and made durable.

' I am aware that brackets Ahave been' constructed of iron and otherv material, and have been* applied to strengthen the connection of the legs to the seat of Ia chair, and I therefore flo-not broadly claim such method of strengthening a chair.

Having fullydescribed the construction and operation of my invention, a

What I claim, and desire to secure by Letters Patent, isl The combination of the bracket A, when so con.-

' structedas to claspnnd fasten to the leg of the c'liair by a partially-surrounding ange, with the 'chair-seat and leg, substantially as and for the purpose'specitied y HARRY H. EVERTS;

and shown.
