UNITED STATES SYLVANUS G. HOPKINS,

OF BOSTON, MASSACHUSETTS.

- FOLDING CHAIR.

' SPECIFICATION forming part of Letters Patent N 0. 326,564, dated September 22, 1885. Application filed April 19, 1884. (No model.)

To all whom it may concern:

Be it known that I, SYLvANUs O. HOPKINS, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Folding Chairs, of which the following is a specification.

The object of my invention is to provide a cheap, simple, convenient, and compact folding chair for transportation and it consists in the construction, combination, and arrangement of the several parts of the chair, as hereinafter more fully described, and set forth in the claim.

Figure 1 represents a perspective view of a folding chair constructed'according to my in vention. Fig. 2 represents a similar view of the same folded. Fig. 3 represents a crosssection through the back-standard and connected portion of the seat-frame detached.

A represents the back-standards, connected together near their upward end portions by a suitable back -support, B, which may be formed of any rigid or flexible material desired and secured thereto in any suitable manner, and between the lower end portions of the said back standards A is pivoted the crossround 0, near each end of which are secured the lower ends of the incline folding supports D, to the upward ends of which is secured the front seat-frame, I, upon which is secured the forward end of the flexible seat E, the rear end of which is secured upon the rear seat-frame, F, the opposite ends of which are connected with the inward faces of the said backstandards A by suitable sliding connections, and to the lower side of the said seatframe F are connected incline folding legs H,

theupper ends of the which are pivoted cenof the screws or bolts being trally or about mid-length to the outsides of the said incline folding supports thereby forming a folding chair, the lower ends of the back-standards Aforming the rear feet or legs, and the lower ends of the said incline foldinglegs H the forward ones, as shown.

The chair-frame thus constructed may be further strengthened by providing additional crossrounds betweeen the folding legs or standards.

The opposite ends of the rear seat-frame, F, are connected with the T-shaped grooves R, formed in the inward faces of the back-standards A, by the screws or bolts S, inserted into the ends of the frame-piece F, leaving a portion near their head ends projecting outward, so as to slide within the said T-shaped grooves R as the chair is opened and folded, the heads inserted within the said grooves B through the enlarged holes or openings shown at the upward end portions of the said grooves.

Having thus described my invention, what I claim is In a. folding chair, the combination of the legs H and braces D, pivoted together, the sliding rear seat-support, F, connected to the said legs, the front seat-support, P, connected to the said.braces, the cross-rung 0, connected to the braces D, and the vertical legsA, provided with grooves and connected with the said seatsupport F by sliding connections, and, extending above the same, are provided with a backsupport, B, as shown and described.
