. nitr te-and more particularly to chairs, and its primary object is to provide a. securing and bracing device for chairs and other arti- Ycles of furniture which will entire] avoid the r 5 use of glue in securingthe parts 0 the article together, and will afford in a single piece of metal a=firm,and reliable securing means for all arts of a' chair. I

he invention consists of a metallic frame of the novel construction hereinafter described, .provided with means for securing it to the seat, legs, and back-bars of a chair.

In the drawing, which forms a part of this specification Figure 1 is a view in perspectlve, of a portion of a chair with m improved securing frame appliedthereto, ig; 2

1s a view in pers ective o the metallic securing frame detac ed, Fig. 3 is a plan view of the blank from which the securing frame is formed, and Fi 4 is a perspective View of one corner of a slightly modified construction of thelframe. I The 'frameis formed from a sheet metal blank such as is shown in Fig. 3, having its upper edge provided with two triangular notches 1, two longitudinal slits 20 each with an intersecting slit 2 and two end recesses The lower edge of the blank is formed with spaced projections 4, having longitudinal s its to provide four depending portions have ing end perforations 5. l

The up er edge of the blank is bent to a horizontal position to provide a plurality of flanges 6 and 7, provided with screw holes 8. The blank is then hent at the four oints 9 to provide a front section 10, paralle side portious 11, and a two- )art rear section 12, the l triangular notches at ordin" bevel surfaces to provide miter joints 13 at the front corners of 5c the chair. The end lugs 14 of the blank are bent forward at right angles to register with each other and are secured together by bolts 15 and nuts lfi-ori like fastening devices.

In case of s 'nkage of the woodc'oniprising the chair legs or seat,the structure mayhereadily tightened up by melans' of' clamping screws 23. The construction shown in Figs. '1 and 2, is 5 adapted for chairs the legs of which arej'redtangular in cross section, but it is obvious 1 that the improvement is equally well-adapted for use upon round legs, by bending the corners and the dependingportions 4 to pro 9 vide round seats or'sockets as illustrated Fi 4. l l

'he invention not only provides a substantial and durable means for securing the.

parts of a chair together, but it is especially ads ted for knockdown chairs, as the parts of t e chair including the improved frame may be disconnected For shipment and easily laced together and secured by iiiiiskilled abor. R roe While I have described the invention as applied to a chair, it is also applicable to a variety of other articles of furniture, such as tables, stands, refri craters and the like; and I would therefore the invention is not restricted in its application to chairs, orlto the exact c m.-lruction shown in the drawing, but includes lll such :From the construction thus 'w1ll be ap are'nt, tlIat-the-fiamepI'oVideS a .snbstantia' securing fdeviceandabrace for ave it umlerstood that :05
