roLnING on cAMP CHAIRk To all whom it may con-cem Be it known that I, Ronenfr L. NorMN, a citizen of the United States,l residing at Bu'alo, in the county of Erie. and State of New (York,` have invented a new and usful Improvement in Folding or Camp Chairs, of which the following is a specification.

This invention relates more particularly to folding or camp chairs of that sort comprising crossed hinged legs connected by flexiblematerial forming tlie Seat, and a hinged back which is adapted to be folded down against the legs.

The object of the invention is to provide a strong and desirable folding chair of this sort, 'which is of simpleand inexpensive construction, and in which the back i's provided with hooks or parts adapted to em-4 brace `the legs to which it is hinged for securely retaining the back in the upright operativeposition and preventing it from swinging rearwardly beyond such upright position and from falling forwardly or be# ing accidentallyknocked down.

In the accompanying drawingsr'Figure 1 is a perspective view of a foldingor camp chair embodying the invention. Fig. 2 is a bottom plan View of the chair folded. Fig. 3 is an enlarged front elevation of one of the back hinges and retaining hooks. Fig. 4 is a side elevation thereof.

Like reference characters refer to like parts in the several figures.

A and B represent the legs of the chair .whichare crossed and hinged together between their ends in any suitable manner, and C represents a piece of canvas or other suitable flexible material7 which connects the upgaer' ends of the legs and forms the seat o the chair. The legs may be of any usual or 'suitable construction, but preferably they are formed by substantiallyt reetangular metal .frames having side bars or rods connected by top and bottom cross bars or rods', and the ends of the top cross rod of the leg frame B at` the rear end of th'w'seatuextend laterally beyond side rods,

of this frame to from hinge pintles d for the ack.

The back of the chair consist-s of a.-U shaped frame E and a piece of. canvas or other suitable material c which is preferably secured at its ends to and connects the side rods of the back frame. The side rods :of the back are preferably bowed Vlaterally vSpeciieatioa of Letters Patents. Patented Oct. 13, 191.4.,

.outward at a a'bove the canvasstrip aand upset to form enlargements at ebelowvthe strip to vprevent it from .slipping out of. place on the side` rods, and the upper por-` tion of the frame is also shown as bent rearwardly somewhat to make the back.` more comfortable.' The side -rods of the back framesare provided above their lower extremities with eyes or perforations e to rem ceive the hinge pintles d, whereby the back 65 is hinged to thel leg frame B so as to fold forwardly. The back strip could, however,

be differently arrangedand. held in place and theback could be hingedto the legs side'r'odsof the -v any other suitable way.

The lower ends of thev back frame below the hinge eyes e are bent inwardly, forwardly -and`upwardly,fforming hooks F. When the back is swung up-l wardly land rearwardly, these'hooks strikey 75` the legs B and prevent the back from swinging backwardly beyond 'the intended@` substantially upright or operative position,

shown in Fig. 1. By forcibly pressing the back rearwardly to its limitY the `ends of the .80

hooks are caused to spring p'ast the Yside rods o flthe leg frame B so as to embrace or bearagainst these side rods with suili-` s cient pressure to prevent the back from swinging. forwardly unless force enough iS 35 applied to it to disengage the hooks'from the legs B. 4The hinge eyes- 5 can slip on the hinge piutles Ato allow -tbis spring action of the hooks. vThe hooks thus not only brace the back and prevent it from swinging backwardly beyond tbe operative position, but they eflectnally retain it in the upright position and prevent it from falling forwardly or being `accidentally knockedA down.

lease the back by the act of swinging the back-.to and from the operative position,

and they are therefore preferable to acateh' or retaining device which has -to be independently operated. At the 'same timek the hooks are integral portionsof the side rods of the back frame and dov not add appreleiably, to the cost of tbe chair; a11d'further-- mortnthe engagement of the hooks with the 1. 'lhe combination of legs` a seat, and a 110 The hooksaro engaged with and 95 vdisengaged from the legs to hold and reback, said back and one' of said legs being hinged together at the rear side ofthe seat, fixed hooked portions on one of said vhinged parts adjacent to -the hinge connection which are adapted to spring intointerlocking en ga gement with said other' hingedf part i and grip the sme with a spring tensionl when the back swung into the operative osition whereby the back is positively from forward or rearward movement.
