SPECIFICATION forming part of Letters Patent No. 572,409, dated December 1, 1896.

Application filed May 16 1896. Serial No- 591,778. (No model.)

To au whom it may concern,.-

Be it known that I, JAMES COOPER, of New York city, New York, have invented an Improved'Ohair-Brace, of which the following is a speciiication.

This invention relates to a brace more particularly designed to be attached to chairs already in use, though it may also be attached to new chairs. By means of this brace the chairlegs are drawn tightly against the rounds and are iirmly secured to the chairbottom, so that an intimate union of all the parts is effected vand great rigidity of the structure obtained.

In the accompanying drawings, Figure lis y a perspective view of a chair provided with my improved brace, and Fig. 2 is a detail of. the staple before being twisted.

My improved brace consists, essentially, of four parts, a staple a, a cross-bar b, and a pair of stay-rods c c. The staple a when attached to the chair has the form shown in Fig. 2. Its shanks ce' are bent inward, so as to cross each other and forni an elongated eye a2, which is closed at both ends. At its free end each shank terminates in a screweye a3. l

The cross-bar b is preferably made of extra heavy wire, and also has a screw-eye b at each of its ends. The stay-rods c are bent centrally to form an obtuse angle and are at their apex provided preferably with a small bulge c'. At their free ends each of the rods c terminates in the screw-eye c2.

In use the staple ct is first screwed to the lower side of the chair seat or frame A, so that it depends centrally therefrom. The crossbar b is then slipped through the upper end of the loop and is also screwed to the seat A. Next the stay-rods care slipped through the lower end ofthe loop, so as to become seated at their bulge c', and the ends of each rod are screwed to diagonally-opposite chair-legs A. The parts being thus all connected the looped or depending portion of the staple is twisted upon itself, Fig. l, by means of a small hand -lever or other tool. By this twisting operation the length of the eye a2 is reduced and the rods c are drawn up at the center, so that they become taut and draw the legs A against the rounds A2 and also against the seat A. Duringthe twisting operation the cross-bar b serves as a stop that prevents the bent staple-shanks from straightening out.

My improved brace can be attached to a chair in a very few minutes, and when so attached will have converted an old and looselyjointed chair into one of great strength and rigidity, which will withstand even a greater amount of rough handling than a chair which is entirely new.

1 A chair-brace composed of a staple having inwardly-bent shanks to form a closed loop, a cross-bar engaged thereby, and a pair of stay-rods adapted to extend through the loop and to be secured to the chair-legs, substantially as specified.

2. The combination of a chair, withastaple secured to the chair-seat, and having bent shanks and a twisted body, a cross-bar eX- tending through the staple, and a pair of bent stay-rods that engage the staple and are secured to the chair-legs, substantially as speciied.
