IMPROVEMENT m FOLDING TABLES.

Specification forming part of Letters Patent No. 18 1,969, dated September 5, 1876; application filed March 11, 1876.

To all whom it may concern Be it known that 1, WILLIAM O. Oseoon, of Chicago, in the county of Cook, and in the State of Illinois, have invented certain new and useful Improvements in a Folding Table; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part' of this specification.

The nature of my invention consists in the construction and arrangement of a folding table, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in which- Figure l is a bottom view of the table folded. Fig. 2 is a longitudinal section of the, same thrown open for use. Fig. 3 shows the con,- struction of the hinges used.

A represents the table-top, of any suitable size. Near each end of the top A are two legs, B B, connected at their upper ends by a crossbar, 0, and hinged to the under side of the table-top'by hinges, hereinafter described, so as to fold inward against the under side of said top.

In the center, to the under side of the top A, is secured a metal spring, D, the ends of which are bent at an angle as shown at a, and in said parts a, are holes for the passage of pins b b, which are fastened in the under edges of the cross-bars O O.

When the legs are thrown downward for use, the pins b enter the holes in the ends a. of the spring, and the legs are by said spring held perfectly firm and steady.

To fold the table, the ends of the spring are simply slipped off from the pins b, and the legs can then be folded inward.

The hinge used in this table consists of an L-shaped casting, G, with center brace G said casting being fastened by screws to the under side of the table-top A. From the then vertical part of the casting projects a pin or round shank, G This shank G is constructed,

as shown in Fig. 3, with a shoulder at w, and

a bisected sleeve, J, placed around said shank. The interior of this sleeve should correspond with the shape of the shank, and on the exterior are formed screw-threads '5. At the outer end of the sleeve is a flange, J.

The shank being placed within the sleeve, said sleeve is screwed into the leg, and there held by a brad or screw through a notch in the top A, the hinged legs B B, provided with.

cross-bars 0, having pins 1), the single perforated metallic spring D, the castings G G with shouldered shanks G bisected'sleeves J,

havin end flan es J and exterior screw-- threads i, all constructed substantially-as and for the purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand and seal this 4th day of March, l876.-
