SPECIFICATION forming part of Letters Patent NO. 632,613, dated September 5, 1899. Application illed June 12, 1899. Serial No. 720,230. (No model.)

To all wwm/ it may concern:

Beit known that I, BAscoiv1L.WYATT, a citizen of the United States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented certain new and useful Improvements in Furniture-Braces; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in braces for bedsteads and other articles of furniture; and it consists in a novel form of device for tightening Wires used for stiftening and holding together the various parts ofthe frame of the article of furniture.

My invention consists of certain novel features and improvements hereinafter described and claimed.

Reference is had to the accompanying drawings, wherein the same parts are indicated byA the same letters throughout the several views.

vFigure l represents a top plan View of my furniture-brace as applied to a bedstead. Fig. 2 represents an enlarged top plan view of the same. Fig. 3 represents aside elevation; and Fig. a is a section taken on the linelt 4. in Fig. 2, looking toward the top of the sheet.

Aand A represent two crossed wires which are secured at their ends to the four corners of the bedstead and to the intersection of which wires the tightening-brace is applied, as hereinafter described.

B represents a circular disk of a concavoconvex form, substantially flat, having a central circular opening B0 and having upon itsperiphery a iiange B, provided with ratchetteeth b. Upon the upper or convex face of the said disk are pairs of hooked lugs, the one pair B2 being situated at opposite points in the same diameter of the said disk and the other pair B3 being similarly situated at opposite points in the intermediate diameter of the said diskand being relatively longer than the said lugs B2, the object being to permit the crossed wires to -be grasped by the said lugs without interference, as will hereinafter more fully appear. A radial arm B'L is either cast integral with or rigidly mounted upon the convex surface of the said disk for being grasped by the hand to turn the said disk or hold the same while the other is being turned.

C represents a smaller disk which ts within the concave side of the disk B, concentric therewith, and has a central cylindrical boss C thereon which extends through the central Vopening B0 in the disk B. Upon this central boss C are a group of axially-extending studs or pins c', preferably four in number, as 6o shown, the said pins being spaced suiciently wide apart to allow of the passage of the wires, as'alsoshown in Fig. 2.

D represents an arm which is either cast integral with or rigidly mounted upon the vdisk C for turning the same, and this arm has mounted thereon a catch D', controlled by spring D2 and having one or more lugs d', by means of which the said catch may be operated. The said catch D' has an exten- 7o sion D3 upon its point, which extension overreaches the flange B upon the disk B, and said catch has an undercut beveled point to engage the ratchet-teeth upon the said disk B. The extended end D301? the catch D will follow the upper surface of the iiange B about the said disk as the catch moves relatively thereto.

The tightening device is applied to the crossed wiresA and A as shown in Figs. l and 8o Y2-that is to say, the Wires will be engaged in their crossed position at their intersection by the pins c', and one of the wires, as A', being beneath the other is engaged by the shorter hooked lugs B2, while the other Wire A being above is readily engaged by the longer hooked lugs B3, as seen most clearly in Figs.

3 and 4, the difference in the-lengths of the two pairs of' lugs rendering it very easy to engage the wires therewith. The tightener 9o thus being applied to the crossed wires the arm or handle B4 is grasped by one hand of the operator while the arm D is grasped by the other hand, and the two arms are moved apart in the direction of the arrows in Figs. l and 2. Duringthis movement the wires are iirmly grasped and held by the hooked lugs upon the upper disk B, while they are bent or looped by the pins c/ upon the lower disk. As the disks are moved with respect to each roo other, as above described, the beveled point of the catch D passes over and engages successively the ratchet-teeth b upon the iiange B of theupper disk B, the overreaching end D3 of the said catch passing along the upper surface of the ange B', as hereinbefore described. Now should the wires become slack there Would be a tendency of the lower disk to fall apart from the upper disk by its own weight, which would occur as soon as the friction between the pins c and the wires became too small to support the said disk were it not for the overreaching end D3 of the catch D', which, engaging above the fiange B on the upper disk, serves to support the lower disk irrespective of the tension upon the Wires. By having an arm on each disk itwill be seen that the tightening operation may be accomplished much more rapidly and with far greater convenience than if there were but one arm upon one disk.v

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

l. In a wire-tightener for furniture-braces, the combination with a circular disk having a central circular opening and a peripheral flange provided with radial ratchet-teeth; a pair of relatively shorter hooked lugs extending from opposite points in the same diameter of the face of the upper side of said disk; a pair of relatively longer hooked lugs similarly arranged in the intermediate diameter;

and an arm rigidly mounted near the periphery of said disk; of a smaller concentric disk fitting the und-er side of the larger disk, having a central cylindrical'boss extending through the said central opening in the larger disk; a group of rigid axial pins extending from said boss; a radial handle rigidly fixed upon the smaller disk; and a spring-actuated latch carried by said handle having a point 4o pass each other when the said disks are in operative relation, substantially as described.

2. In a wire-tightener for furniture-braces, the combination with a circular disk having a central circular opening and a peripheral ange provided with radial ratchet-teeth; a pair of relatively shorter hooked lugs extending from opposite points in the same diameter of the face of the upper side of said disk; a pair of relatively longer hooked lugs similarly arranged in the intermediate diameter; and an arm rigidly mounted near the periphery of said disk; of a smaller concentric disk fitting the under side of the larger disk, having a central cylindrical boss extending through the said central opening in the larger disk; a group of rigid axial pins extending from said boss; a radial handle. rigidly fixed upon the smaller disk; a spring-actuated latch carried by said handle and having a beveled point arranged to engage the teeth on the periphery of the larger disk and an extension of said point overreaching the ange on the larger disk and bearing thereon, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

BASCOM L. VYATT.
