FOLDING- CHAIR.
-APPLIOATION FILED OUT. 1, 190a.

- INVENTOH Jigv/zeh a 1511126 A TTOHNE Y S UNITED STATES STEPHEN GEORGE KRILE, OF SAN FRANCISCO, CALIFORNIA.
FOLDING CHAIR.
To all whom it may concern:
Be 1tknown that I, STEPHEN Gr. KRILE, a sub ect of the Emperor of Austria-Hungary, and a resident of San Francisco, in the county of San Francisco and State of Califorma, have invented a new and Improved Folding Chair, of which the following is a full, clear, and exact description.
The purpose of the invention is to provide a very simple and durable form of folding chair, that may be made so that the base and the seat can be separated and compactly folded, and wherein the seat and back stays may be removed and readily replaced, and wherein when the seat and back sections are properly placed upon the base section the chair will be as firm as a one piece chair.
It is a further purpose of the invention to provide a chair in which the base is a folding one, having suitable folding braces and stops to prevent spreading, and to provide the chair with a seat and back section having a hinge connection; all of which abovementioned parts may be made light and strong.
In the drawings that illustrate my invention, I have shown the preferred manner of attaching the seat and back stays, and like wise the preferred manner of attaching the base to the upper structure of the chair, but I do not confine myself to such construction, since it may be varied in details and good results be obtained.
Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.
Figure 1 is a perspective view of the improved chair in position for use; Fig. 2 is an edge view of the folded base; Fig. 3 is an enlarged perspective view of a portion of the side bar of the seat and a portion of a stay or strap in position therein; Fig. 4 is a transverse section through the part shown in Fig. 3; Fig. 5 is an edge view of the folded back and seat; Fig. 6 is an edge view of a stay or strap for the seat and back; Fig. 7 is a detail view of one of the folding braces viewed from the side; and Fig. 8 is a detail perspective view of a portion of the seat frame and base frame illustrating how they are connected.
The base A consists of four folding, crossed legs w, w, 00 and 00 The legs 00 and Specification of Letters Patent.
Application filed October 1, 1908.
Patented Feb. 21, 1911.
Serial No. 455,651.
x and the legs a) and .70" are connected at their central portions by suitable pivot pins 10, and are prevented from spreading too far when set up by brackets or knees 11, carried by one leg of each set. A notch or recess 12, is produced at the upper portion of each of said legs, which recesses or notches, as is particularly shown in Fig. 8, are substantially V-shaped, but the inner members 12 are longer than the opposing or outer members 12", as is also shown in Figs. 2 and S. The lower portions of the legs 00 and 00 are connected by a brace 7 and their upper portions by a corresponding brace y, while the lower portions of the legs :0 and 00 and their upper portions are connected by similar braces, designated respectively as 1/ and y, as is shown in Fig. 1. The several braces are pivotally connected with the legs and each consists of two sections 13 and 1-1, in turn connected by rule joints 15, but the joints of the lower braces break in an opposite direction to the joints of the upper braces, as is shown in Figs. 1 and 2.
At the side of each brace. opposite that at which the rule joint 15 is formed, one member is provided with a notch 16, and the other member with a spring 1", that crosses the joint and is provided with a head 18, adapted to enter the notch 16 of the opposing member when the braces are straightened out, as is shown in Fig. 7.
lVhen the base is folded, the legs cc, a2, m and 00 lie parallel and close together. as is shown in Fig. 2, and the folded upper braces point in the direction of the hinges of the lower braces, as is also shown in Fig. 2.
The body of the chair consists of a seat section B and a back section B. The frame of the seat section B consists of side members 19, made of wood or metal, and when made of metal they are hollow in the interest of lightness, as is shown in Fig. 4E. The frame of the back section B consists of corresponding side members 20, the side members of the two sections B and B being con nected prefeably by rule joints 21, as is shown in Figs. 1 and 5, so that one section can fold flatly upon the other, as is illustrated in Fig. 5.
The side members 19 and 20 of the seat and back, are provided with longitudinal channels 23, in their front faces covered in part by face plates 22. Slots C, in any desired number, are produced in the face plates for the seat and back and each slot is divided into a wide section a and a connecting narrower section 0, as is particularly shown in Fig. 3. These slots C are adapted to receive angular flanges 24:, inturned beneath the bottom end portions of stays or straps D, preferably made of metal, although other material may be employed.
The straps or stays D are removable, and in placing them in posit-ion, the flanges 24 are entered into the wider sections 0 of the slots and are then slid into the narrower sections 0.
IVhen the chair is to be set up, the base A is unfolded and the braces connecting the legs are straightened out. Next the back and seat are unfolded, the stays, if removed, are placed in position and the side members 19 of the seat B, are made to enter the notches 12 in the upper portions of the legs of the base, as is shown in Fig. 8, and then pins 25, or equivalent fastening devices, are passed through the longer members 12 at the top of the legs into the side members of the seat.
Having thus described my invention, I claim as new and desire to secure by Letters Patent:
1. In a folding or camp chair, the combination with a base, consisting of crossed, pivoted legs, braces for the legs, constructed in hinged sections, which braces are in staggered arrangement, and latches for the braces, of a seat, means for removably attaching the seat to the legs of the base, a
back hinged to the seat, and means for limiting the spread of the legs.
2. In a folding or camp chair, the combination with a seat, and a back mounted to fold thereon and therefrom, of a support for the seat, comprising crossed and pivotally-connected legs, stops limiting the spread of the legs, braces for the legs, constructed in sections having a rule joint connection, the rule joints for the braces for the same set of legs facing in opposite directions, and latches for the braces.
3. A camp chair or seat, the side members whereof are provided with slots in two widths, and straps provided with enlargements at their ends that freely enter the wider portions of the slots, but are in clamping engagement with said side members when in the narrower portions of the slots.
4. In the construction of camp and similar chairs, opposing side members, having longitudinal slots therein, which slots are in two connected sections of different widths, and straps having enlargements at their end portions, which enlargements have vertical and lateral play in the wider sect-ions 0f the slots, but lateral play only in the narrower sections of said slots.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses STEPHEN GEORGE KRILE. Witnesses:
