CHAIR-BRACE.
SPECIFICATION forming part of Letters Patent No. 359,891, dated March 2v2, 1887.
Application filed July 23. ISES. Serial No. 208,868. (No model.)
To @ZZ whom, it may concern.-
Beit known thaty I, Janes F. Snizer-infr, a citizen of the United States, residing at Man chester, in the county of Hillsborough and State of New Hampshire, have invented certain new and useful Improvements in Chair-Braces, of which the following is a specification, reference being had therein to the accompanying drawings.
This invention relates to chair-braces which are designed to iirmly hold the rounds and legs in their respective sockets.
The object of the present invention is to provide a brace which shall be simple in construction, cheap of manufacture, readily applied to either old or new chairs or stools, and durable in use, and also to prevent the rounds and legs from becoming loose by reason of shrinkage of the wood..
The invention consists of a series of springbraces, the upper and lower ends of which are respectively secured to a center plate and the legs, the plate being adjustable upon a threaded rod,which is hooked over two wire rods which cross each other at right angles and are suitably secured to the lowerv face of the chair seat or frame, all as will be hereinafter described, and more particularly pointed out in the claims.
In the drawings, Figure lis an elevation of a chair having my improvement attached thereto. Fig. 2 is a detail view showing the manner in which the hook which supports the plate passes over the transverse bars. Fig. 3 is an elevation of a stool with the springbraces hanging from their supporting-plate. Fig. 4 is a bottom plan view. Fig. 5 is a detail view; and Fig. 6 is an elevation of a bitstock, partly in section, employed by me in tightening the nut on the brace-supporting plate.
Referring to the drawings, in which like letters of reference refer to like parts, A designates the seat of a chair or stool having legs B and rounds O, which are soeketed, respectively, in the chair seat and legs in the usual manner, with this exception, that when my brace is employed it is not necessary touse glue in the joints.
D is a series of spring-braces, which are secured at their lower ends to the chair-legs, preferably by means of screws, while their rod F, when the nut f 2 is given two or three turns in order to support the plate upon said rod while the lower ends of the spring-braces D are Vbeing secured to the legs, after which said nut is forced upwardly upon the rod by means of a bit-stock, substantially such as I have shown in Fig. 6, having a socket which ts upon the nut, but permits the threaded rod to pass upwardly therein as far as may be necessary to draw the braces from the position indicated by dotted lines o in Fig. 6 to the po sition indicatedby full lines. The dotted lines p indicate the position that an ordinary straight brace would occupy. y
After the springs of the braces have been partially drawn out by forcing the nutf2 upwardly upon the rod F, that portion of the lower end of the latter which projects below the nut is cut off with a pair ofpiuchers. The effect of the spring-braces, after they have been secured in the manner described, is to exert a constant contracting force upon the legs of the chair, thereby serving to draw them in upon the rounds in case of shrinkage of the wood, which takes place more or less in all wooden structures, and which it is essentially necessary to provide against in chairs and stools.
I have found, after applying my brace to a large number of chairs, 85o., during the past year, that the legs and rounds never become loose, and therefore never require any further tension to'be put upon the braces by adjusting the securing-nut.
I do not limit myself to the exact form and proportion of parts herein shown as an embodiment of my invention, the essential features of which will be understood from the foregoing description in connection with the drawings.
I am aware that it is old to secure a se- ICO ries of wires at one end to the seatof the chair and at thek other end to the legs, and to provide a straining device for securing tension on said Wires, and I do not desire to claim such construction.
That I elainl, and desire to secure by Letters Patent, is-
1. The Combination, with a perforated plate having means for supporting it from the lower face of the chair, of a series of spring-braces secured to the said pla-te and to the legs of the chair, as and for the purpose set forth.
2. The combination, With a perforated plate supported from the lower face of the stool or chair by means of a nut and threaded rod hav#` ing; a hook at its upper end, which passes over two rods connected at their ends to the seat at the point where they intersect, of a series of spring-braces which are hooked to the peripliery of said plate and secured to the legs 3. In combination with the transverse rods 2O of the chair, as and for the purpose set forth.
secured at each end to the seat, the threaded I
