b g in chairs containing folding x -legs the front Be itknown that I, ALBERT D. WHITMORE,

legs extend npand are united to, or prolonged to form, the back,'and the back legsextend forward to the front edge of the seatframe.

In my folding chair the back and-back legs form one frame, and the legs do not cross.

The front legs h of the chair are attached to the seat by the pivot-pins or hinges l, and the bars m m are pivoted at their ends to the front and back legs, respectively, and the cross bar or rail it connects the front legs h h, and the cross bar or rail 1' connects the back legs a a, so the lower portions of the legs are sustained in position relatively to each other; but the chair can be folded for packing or transportation. 1

I claim as my invention- 1. The folding chair made with the back and back legs forming one frame, in combination with a seat-frame that passes in between the back legs, and is pivoted directly to such legs, substantially as set forth.

2. In a folding chair with the back and back legs in one'i'rame, the combination of a diagonal brace, rigid seat or seat-frame, and front legs connected with such seat, substantially as set forth.

3. The combination, in a folding chair, of a frame forming the back and back legs, a seat, front legs, connections from the back legs to the front legs, and diagona brace, substantially asset forth.

4. The combination, in a folding chair, of a seat and back frame hinged together, an diagonal braces, extending from the side pieces a a, and connected with slotted guides at theseat, substantially as set forth.

Signed by me this 19th day of March, A.

State of Massachusetts, have invented an Improvement in Folding Chairs, of which the following is a specification:

his chair is made with one frame forming the back and back legs, and the folding seat is jointed to this back-frame, and there is a brace that serves to hold the seat in its proper osition when the chair is folded. This brace extends from the back-frame below the. seat to a slot at the under part of the seat, so that the seat is held in the proper relative position to the baclcframe. a

In the drawing, Figure 1 is a perspective view of the chair, and Fig. 2 is a section through the seat and back-frame.

The back-frame is com posed of the side pieces ac and the cross-pieces or rails b, and the rigid seat or seat-frame cis hinged to this back-frame at d, and swings upwardly against the back when the chair is folded. The pivots connect the seat or seat-frame directly to the back legs, instead of the seat being hinged to a cross-bar and folding downwardly, as heretofore employed. The seat of the chair may be made a frame, 0, and filled in with cane or flag, or covered with carpet or any other suitable material; or the seat may be a wood bottom of is in position for use it is held firmly by the der side of the seat. The diagonal brace is seat cannot fold downwardly as the back of .A. D.'WHITMOBE. extends down below the seat, and forms the back legs of the chair, instead of the legs that support the v t being folding -legs, as have heretofore been generally usedin foldingchairs.
