IWFRQVEMENT iN FLDING TABLES.

Specification forming part of Letters Patent No. 50,226, dated April 28, 1874; application filed January 6, 1874.

To all whom it may concern: Y

Be it known that I, SYLvnsrnR P. BAB- eooK, of the city of Adrian, in the county of Lenawee and State of Michigan, have invented a new v and useful Improvement in` Folding-Leg Tables, of which the following is a true and accurate description, reference being had to the accompanying drawing, and to the letters of reference marked thereon, and being a part of this specification, in which- Figure l shows my improved folding-leg table in perspective. Fig. 2 is an inverted plan of the table, showing the cleats, springs, braces, and hinging-ears, with a portion of the legs open and a portion of them closed. Fig. 3 is a side view of the brace.

.Similar letters of reference indicate correspondin g parts in the several gures.

rlhc nature of this invention relates to an improvement in the hinging and bracing of the legs of a light table, whereby the same may be qnickl y and compactly folded, so as to be put ont' of the way when not wanted for usc, and consists in the devices hereinafter described and more fully set forth.

In the drawing, A is the top or cover, and ismade in any desirable form or thickness, or of any desirable material. B B are cleats fastened to the under side of the cover, in any desired position or place, by means of a sufcient number of screws, or other kind of fastening to hold them firm, and must be sufficiently strong to keep the top from warping, and also make a firm support for the springs, braces, and legs. C C C C are the legs, secured to the cover by bolts passing through the ears E and cleat B, or by means of a woodse'rew. rllhe legs are secured and braced to the cleats in pairs, and on the opposite sides and ends of the same. E E E E are cars formed in shape of a right angle, one leg of which is fastened to the top A by means of several screws, and at a suitable distance from the cleats B to admit the legs. The bolt K acts as a hinge for the leg, and passes through the upright arm of the ear, and through the leg into the cleat, and binds the leg firmly between the cleat and ear, and prevents any lateral movement of the leg toward the ear or cleat. F is a brace, and gives the transverse support to the legs. One end of the brace is perforated and fastened to the leg, five or six inches from the bolt or hinge, by means of a screw. The other end of the brace is carried up to the cleat, and the notch G engages with the screw H. I is a spring, made ot' wire, ten or twelve inches long, with an arm, t', at one end and a hook, c, at the other end. The hook e is bent out from the body of the spring at right angles to the arm fi, so that when the arme' is driven into the cleat at the upper side the body of the spring will lie along lengthwise of the cleat, while the hook o at the other end passes down and over the brace F, justin front of the screw H, and betweenthe top of the leg and the screw. H is a screw driven firmly into the cleat, about fifteen inches from the hinge-ear E, and in the side of the cleat toward the leg, and projects sufficient to let the brace slide on the body of the screw between the head and the cleat. The spring I holds the brace iirmly up, so that in opening the leg, when the notch G comes to the screw H, the notch is forced over the screw and secures the leg in a permanent position.

In order to close the leg the brace is pulled down with the hand until the notch G is dis engaged from the screw H, when the brace will slide easily along under the hook in the spring until the leg lies alongside of the cleat with the brace and spring in a very compact form.

I claimrJlhe combination, with the top A, cleats B, and legs O, of the braces F, springs I, and catch-screw H, substantially as described, and for the purposes set forth.
