UNITED STATES PATENT OFFICE.

HORACE L. FREEMAN, OF LEXINGTON, NORTH CAROLINA, ASSIGNOR TO BA'XTER SHEMWELL, OF SAME PLACE.

FURNITURE-TIGHTENING DEVICE.

SPECIFICATION forming part of Letters Patent No. 505,979, dated October 3, 1893 Application filed 51115241893. Serial No. 478,793. (No model.)

To all whom it may concern.-

Be it known that I, HORACE L. FREEMAN, a citizen of the United States, residing at Lex ington, in the county of Davidson and State of North Carolina, have invented certain new and useful Improvements in Furniture-Fastening Devices; and I do declare the follow-' ing 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, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention is an improvement in furniture tightners and the object of the invention is to provide means for tightening or clamping together the opposite sides and legs of chairs, tables bedsteads and similar articles of furniture.

I have illustrated my invention in the accompanying drawings in which Figure 1 is a plan view of my invention as applied to the framework of a bedstead for tightening the same. Fig. 2 is an enlarged view similar to Fig. 1. Fig. 3 is a side view or edge view of the device and Fig. 4 is a view at right angles to Fig. 3.

In the drawings A, A are the sides and end pieces of the frame of the bedstead respectively, these parts being representative of any framework of an article of furniture which it is desired to tighten, and A are the corner posts or legs.

The clamping device or tightening device is connected to the different parts of the framework by wires and so arranged that its operation serves to draw all parts to which it is connected toward the center. It consists essentially of two parts B, B substantially the shape of winged collars, which have a clamping bolt 0 passing through the openings in the collars, these openings being large enough to permit the clamping bolt to slide freely therein. The wings I) of the collars B, are connected by toggle levers D substantially as shown. The bolt is headed at one end as shown at C and at the other end is screw threaded and provided with a thumb nut O by means of which the collars B may be drawn together thus forcing the toggle levers apart.

For connecting the device to the framework by the wires I provide eye bolts or eye screws in the corner posts of the framework as shown at E through which the wires are passed and also provide projections F from the upper face of the toggle arms over which the wires are designed to pass as will be hereinafter described. These projections are in the form of rivets which extend up but a short distance above the face of the arms and are provided with overhanging heads which form grooves c for the reception of the Wires. I prefer to use one wire which passes through the eye bolts in the posts upon one side of the frame and thence over the rivets on the arms engaging the grooves previously mentioned and from this point is carried through the eye bolts upon the other side where the two ends may be united as shown.

When applied to the framework of the article to be tightened and before the tightening effect is produced the collars B are at their greatest distance from each other. In order to draw the posts, side pieces and end pieces of the frame together it is only necessary to screw up the thumb nut O which will cause the collars B to advance and move the projections which engage the wires toward each other thus drawing upon the wires and through them upon the corner posts and causing them to be drawn tightly together. In order to provide additional tightening means for the framework I provide cross wires G which are connected to eye bolts H in the sides of the frame intermediate the eye bolts E, these serving to force the side pieces tightly against the ends of the slats. The other ends of these wires are secured to projections I, which I prefer tohave in the form of extensions of the pivots which connect the toggle arms, and are provided with eyes 2', serving to guide the overlapping wires. These wires as will be observed overlap each other, the wire which is connected with the frame upon one sidebeing connected to the projection I upon the opposite side and thus when the clamping nut C is operated and the pivots of thetoggle levers forced apart the inner ends of these wires will be drawn in opposite directions. I have also provided perforations b in the collars B and wires maybe extended fromthese perforations to eye bolts K in the end pieces of the bedstead.

1 claim as my invention- 1. A tightening device, consisting of the adj usting bolt, the winged collars movable thereon, the thumb nut engaging the bolt, the toggle levers having their inner ends pivoted together and their outer ends pivoted to the wings of the collars, the set of tightening wires connected to the bed frame and to the toggle levers, and the set connected to the wings of the collar and to the bed frame, as set forth. 7

2. A tightening device consisting of the adjusting bolt, the thumb nuts thereon, the winged collars movable on the bolt, the toggle levers having their outer ends pivoted together and their inner ends'pivoted to the wings of the collars, the projections on the toggle levers, the bed frame, the eyes on the frame, the continuous wire engaging the eyes at the corners of the frame and the projections on the levers and the wires engaging the eyes at the ends of the frame and connected to the wings of the collars.

3. A tightening device for furniture comprising the adjusting bolt the thumb nut, the winged collars on the bolt, toggle levers connecting the wings of the same, a clamping bolt passing through the openings in the collars, projections carried by the levers, a continuous wire engaging said projections and passing through eye bolts located upon the corner posts of the framework of the furniture, projections extending from the pivot points of the toggle levers and wires connecting each of said projections with the frame upon the opposite side, substantially as described.

In testimony whereof I affix my signaturein presence of two witnesses.
