SPECIFICATION forming part of Letters Patent No, 582,136, dated May 4, 1897.

Application filed September 21, 1896. Serial No. 606,534. (No model.)

T 0 all whom it may concern.-

Be it known that I, CARLTON O. COMFORT, residing at Bristol, in the county of Bucks and State of Pennsylvania, have invented a new and useful Folding Chair, of which the following is a specification.

This invention is a new and useful folding chair, the object being to provide an exceedingly cheap, simple, and durable construction of chair which can be folded into a small space and carried about and one which can be quickly and easily opened and will be capable of sustaining considerable weight after being properly opened and set up.

Another object is to provide a detachable back and seat whereby the folding into a small space is facilitated.

With these various objects in view my invention consists in the peculiar construction of the various parts and in their novel combination of arrangements, all of which will be fully described hereinafter and pointed out in the claims.

In the drawings forming a part of this specification, Figure 1 is a view showing the chair set up ready for use. Fig. 2 is a central vertical section taken through the supporting standard and tube. Fig. 3 is a detail sectional view on the line 3 3 of Fig. 2.

In carrying out my invention I employ a tubular standard A, having ears or lugs B at the lower end, between which are pivoted the supporting-legs C, said legs being properly spaced by means of the brace'arms D, which are pivotally connected to the legs near their center and are connected at their inner ends to a collar E, fastened upon the end of the central shaft F by means of an end G.

At the upper end of the tube A are another series of cars 11, to which are pivoted the arms I, said arms being held in the proper position by means of the braces K, which braces are pivotally attached at their inner ends to the upper end of the shaft F.

The rear arms I are pivotally connected at their upper ends to the back-braces L, said back-braces being connected at their upper ends by means of a cross-piece M, jointed at M The forward arms I are pivotally connected to the tubular arms N, in which slide the rods N, said rods N and the tubular arms N constituting the arms of the chair, and it will be observed that they connect the back-frame with the front of the chair.

Suitable means are provided to preventthe rods N being withdrawn from the tubes N, and it will be of course understood that the arms N and I are pivotally connected and also the rods L and N.

The back O is constructed of canvas or other fabric, and likewise the seat I, said back and seat being attached to the frame by means of hooks O and P, respectively, which en a e the rin s or e es 0 and P carried by the frame.

By this construction the back and seat can be readily removed from the frame, and then by forcing the central shaft upwardly the entire framework can be folded into a compact mass, and the canvas back and seat can be wrapped around the same, thereby providing a chair in a folded condition which can be readily carried about and set up whenever desired.

Having thus described my invention, what Iclaim as new, and desire to secure by Letters Patent, is-

1. In a folding chair, the combination with the tubular standard, the shaft therein, the folding arms and legs, the telescoping side arms, the back members and the top piece, said top piece being hinged substantially as and for the purpose described.

2. In a folding chair, the combination with the tubular standard, of the legs hinged to the lower end thereof, the arms hinged to the upper end thereof, the central shaft, the braces attached to the lower end of the shaft and connected also with the legs, the braces attached to the upper end of the shaft and also connected with the arms, the back members pivotally connected to the rear arms, a top member connecting the back member, and hinged at the center, and the side arms connecting the forward arms and the back members, said side arms consisting of the tubular portion, N, and the rod portion N, all arranged and adapted to operate, substantially as shown and described.

CARLTON O. COMFORT.
