ltheinvention consists inadevice of vthe class vandfor the purposespeciiied whichis simple in construction and which is rconstructed Vas hereinafter described and claimed. n

, The invention is fully disclosed in the following specification, of which Athe accompanying drawing forms a part,in which the separate partsV of my improvement `are designated by suitable reference characters in each Which?. 1 l

of the views, and in j In Figs. 1 and f2 of the'drawing I lin 'avefindicated for thepurpose of illustrating one method of carrying my invention into effect,a chair frame I0 consisting of l a single elongated tube or rod which is fashioned` to form centrally of the rod a 4U-shaped base consisting of a back cross-memberV I I and forwardly extendingrandvparallel side Fig. 3 vis an enlarged. section on` the line 3 3 @i5 members I2 continuing at their forward ends in upwardly extending and slightly reclining leg `members I3, the upperends of which are curved backwardly asv seen at. I4 to extend into the armrests I5, thus producing as viewed Vfrom the side of the chair, note Fig. 1, a substantially U-shaped spring chair'frame which provides resilient movement of the seat member I 6 and backrest Il with respect to a supporting surface upon which the base parts I I and I2 are arranged,the curvature as at I8 providing Athis spring action. The frame I0 may be constructed of any suitable materialand may be painted, plated orf-,otherwise coated y to provide the desired finish thereto. However, in using certain types of `materials and metals, coatings or other iinishings are not` absolutely essential. This isespecially true in theuse of certain types of wood or rust or stain-proof metals.

The seat member I6 and backrest I'I are each of identical construction; that is to say, are made from a single sheet of material, such for example, as sheet metal having angularly :extending side flanges I9 and angularly extending end flangesmZll and .2LH The flanges 20 are so disposed with, re-V spect to the main body portionof thesheet-as to arrange the seat member I6 `and the backrest I1 in the desired angular relationship to each other as ris illustrated in'Figs. 1 and 4 of the draw ing; that is to say to maintain the forward end of the seat member slightly higher than the rear end thereof and to incline the backrest infthe manner shown to provide a comfortable chair. t

Arranged upon the outer surfaces of the seat ymember I6 and backresty I'I is suitable upholstery,

which in the construction shown, consists of a padding 22 of suitable cushioning material which may be offany desired thicknessdepending upon Vthe cushioning effect which is required.` This material may be suitably cemented or otherwise secured to the surface of the sheet fromwhich the seat member I6 and backrest I'I are formed, orl .simply laid thereon and retained in position by the facingsemployed for securingthe outer facving material 23 in position. l This facing mate- .rial may be of any type and kind of fabric such vas jcanvas, leatherettes, leather, and the like.

Thesel materials maybe of the same or contrasting colors or designs on thechair 4and seat member `depending entirely upon the ornamentation vdevices 26` for-securely coupling the flanges 2D together to form ofthe seat I6 and backrest "Il of the facing material.

a single L-shaped unit. One eyelet 25a is also employed centrally of the side flanges I9 of the backrestso as to receive bolts Zlin coupling the backrest to the"1ear ends of the arms I5;r The forward end portions of the flanges I9 of the seat member are somewhat enlarged as seen at ISQ.-

respect to each other through the medium of the bolts 26, and the two parts, namely seat and backrest, may be nested one within the other as seen in Fig.:'6 and a'series of the chair frames In these end portions are arranged two eyelets f 25h to receive two bolts 28, note Fig. 3, for attaching the forward end of the seat member with the upper ends of the legs I3.' The usejof the twof bolts in each leg I3 will maintain the seat and backrest in rigid position withinthe frame; thatl is to say, in conjunction with the blots '21.

It will beV apparent however,

that the stress or'strainisr taken up largely bythe foldvof the material-around `'the lower 4edges of the' flangesy and isvnot localized on the l fastening devices whichareemployed. The-final step in "completing the fior-mation of teach part, namely A'theseat'and backrest,censists in bendingth'e free ends of the flanges 2-I `inwardly Aas seen atia, note Fig. 5of`the -drawing,^so as te draw l:tl-ie facing material "23v tig-lA Ay 'upon the seat and backrest.
