FOLDING TABLE.

SPECIFICATION forming part of Letters Patent No. 290,932, dated December 25, 1882.

Application tiled April 4,1883. (No model.)

To all whom t may concern:

Be it known that we, BENJAMIN H. RIoII- AEDsoN and BENJAMIN P. RIoIIAEDsoN, citizens of the United States, residing, respectively, at Milton, in the county of Norfolk and State of Massachusetts, and at Boston, in the county of Suffolk and State of Massachusetts. have jointly invented certain new and useful Improvements in Folding Tables; and We do hereby declare that the same are fully described in the following specification and illustrated ina-he accompanying drawings.

The obj ect of this in vention is to give greater firmness and stability to folding tables than have hitherto been attained.

Our improvements secure the spread legs of the table against lateral strains from either direction, automatically open the brackets when the legs are spread, and hold the legs in position when closed.

In the drawings, Figure l is a side view of the table spread for use; Fig. 2, a plan of the under side with the legs and brackets folded;

' Fig. 3, an enlarged perspective 4view of part of the table invcited, and Fig. 4.- a detail in section.

A is the table-top, B B, the legs, hinged beneath it at H, and united in pairs at each end of the table by panels C, folding with the legs, as in Fig. 2.

E E are folding brackets, preferably metallic castings, having their bearings F F in a line at right angles to the axes of the leghinges, so that when the legs and their connecting-panels are spread perpendicularly to the top A, the brackets may be opened out into a plane at right angles to both. The panels are in the plane of the outer faces of thelegs, so as to have room beneath them,when folded, for the bracket and spring G. The inner face of each panel bears, near its lower edge, a loop or slotted plate, D, with which a terminal projection, c, on the bracket E engages when spread, so as to hold the legs firmly against strains, tending either to close them or spread them more widely. Fig. 3 clearly shows the projection e in position inthe slot of the plate D, the edge of the bracket being recessed to admit it, as seen in Fig. 2. The shape of the bracket is also peculiar, in that it is arched or hollowed out between its bearings to receive the spring G, having an arm, which extends beneath the bracket and tends to open it out as soon as the legs are spread. The panels, however,when folded, keep the brackets down, as will be clear from Fig. 2. The brackets are in their turn each formed with avertical shoulder, E, lying close to the edge of the folded panel, as in Figs. 2 and 4,so that until the bracket is depressed against the power of the spring 6o the legs and panels will not open, because the edge 0I" the panel strikes the shoulder E. A transverse cleat, K, is secured near each end of the table. It is notched near its ends, as in Figs. 2 and 3, to receive the ends of the 65 legs and support them on three sides, while` they bear squarely against the under side of the top A. The panel C also bears, along its whole length, upon this cleat when the legs spread. The cleat also forms a bearing for 7o the bracket E, besides supporting the top against warping.

, We claim as our invention- 1. In a folding table, the top A, hingedlegs B, united in pairs by the panels C, carrying the loops or slotted plates D, in combination with the brackets E, provided with the terminal projections e, adapted to enter the slots of the plates I) and support the legs rmly against lateral strains from either direct-ion,

substantially as set forth.

2. The table-top A, hinged legs B, and panels C, in combination with the swingingbrackets E, each having a vertical shoulder, E', and with a spring, G, tending to spreader unfold the bracket, and thereby to hold said shoulder against the upper edge of the folded panel, substantially as and for the purpose set forth.

In testimony whereof we hereto afX our signatures in presenceof two witnesses.
