ALANSON BINGHAM, OF SURRY, NEW HAMPSHIRE.

IMPROVED CHAIR-SEAT.

Specification forming part of Letters Patent No. 55,605, dated June 19, 1866.

To all whom it may concern:

Be it known that I, ALANSON BINGHAM, of Surry, in the county ot' Cheshire and State of N ew Hampshire, have invented certain Improvements in Chairs, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part ot' this specification, in Which- Figure l is a plan of the seat of a chair attached to its frame according to my improved method. Fig. 2 is a section on the line a: x of Fig. l. Figs. 3, 4, 5 and 6 are enlarged sections, representing my improved method of attaching the seat to its frame, together with niodications of the same.

Nly invention relates to certainy improvements in chairs for which Letters Patent ot' the United States were granted to myself and Osmore A. Bingham, on the lith day of April, A. D. 1866; and my inventiononsists in attachin g a seat composed of a single thickness oi' strips of oak, ash, or other suitable wooden material to a frame provided with slits, or slits and grooves, into which the ends of the strips are passed and securely confined to the frame.

To enable others skilled inthe art to understand and use my invention, I will proceed to describe the manner in which I have carried it out.

In the said drawings, Arepresents the pieces composing the frame of a seat of a chair, secured to each other in any well-known manner. Extending through from the top to the bottoni ot' each piece A of the frame are formed two narrow slits or openings, a b, within which are passed the ends of the strips c of the material from which the seat is to be made, the method of weaving which will now be described.

The end of a strip of the material is first passed down through the slit a, in either the back or front piece, A, of the frame, and at a short distance from the corner thereof, when the end of the strip is bent up through the inner slit, b, where it may be cut oft' flush with the upper side oi' the piece, as seen at d, Fig. 3, or be drawn up and laid over the top of the piece, so as to extend to its inner edge, as seen at e, Fig. 4C, the portion thus laid over being pressed down snugly in place by the strip, when carried over to the opposite piece, to which it is secured in a manner similar to that just described, the strip being drawn tightly before being cut off at either of the points above mentioned. Each strip, after being laid on, is pressed up by hand toward the center ot1 the front and back piece, whereby they are still further tightened, the distance between the slits increasing from the sides to the center of the front and back pieces'of the frame.

The strips laid on in this direction constitute the Warp. (See red arrow.)

The strips constituting the filling (see blue arrow) are now entered within the slits of one of the side pieces, A, near the frontpiece, and are run alternately over and under each strip composing the warp, when, after being cut oft', they are pushed up toward the front piece, where they are securely locked in place, the distance between the slits increasing from the back to the front piece, whereby the strips are drawn tightly as they are pushed along therein, as described.

j' are strips which may be set into the slits a b after the seat is woven, for the purpose of V wedging the ends of the warp and tillin g and keeping them from drawing out.

Each piece A is provided with a screw, 7, which enters from the inside and passes into the piece a sufficient distance to draw the parts nearer to each other, thereby holding the strips tightly in place and givin g additional stiffness to the seat.

Instead of forming two slits a, b, Within each piece A of the frame, one of the slits may be omitted, and a groove, g, (on the inside or outside ofthe other slit,) may be substituted therefor, and the ends of the strips secured therein, as shown in Figs. 5 and 6, without departing from the spirit of my invention.

If desired, cement may be used in the groove g to hold the ends of the strips more securely. v

A seat constructed and attached to its frame in the manner above described is more durable and can be furnished at a less cost than those made in the ordinary way.

What I claim as my invention, and desire to secure by Letters Patent, is-

Attaching a seat composed of a single thickness of strips 'of oak, ash, or other suitable wooden material to a frame by means of slits, or slits and grooves, substantially as described.
