FOLDING TABLE.

SPECIFICATION forming part of Letters Patent No. 250,878 dated December 13, 1881.

Application filed August 21, 1880. (N0 model.)

To all whom it may concern:

Be it known that I, FREDERICK M. BRUSH, of Potsdam, in the county of St. Lawrence and State of New York, have invented a new and valuable Improvement in Folding Tables; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a partof this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawings is a representation of a perspective view of this invention. Fig. 2 is an enlarged detail view of the triangular rabbeted block and its connection.

This invention has relation -to tables of light character for games and other temporary purposes; and it consists in the construction and novel arrangement of the triangular prismatic center block rabbeted around its upper portion, the three legs pivoted to said block below the rabbeted portion and notched in the inside faces of their upper ends, the slotted metallic braceslips pivoted in the rabbets of the center block and engaging pins on the inside faces of the legs, and, in connection therewith, the rounded top, adapted to be pressed into the notches in the upper ends of the legs, which are sufficiently elastic to hold its edge, all as hereinafter shown and described.

In the accompanying drawings, the letter A designates a vertical center block of triangular prismatic form, having its upper portion rabbeted on the three sides, as shown at B.

0 indicates three legs, which are flat on the sides, and are pivoted to the lower portion of the block A by means of screws to, having the usual washers, I), under their heads to prevent undue wear.

D represents small metallic brace slips, which are pivoted, by means of screws d, at one end to the upper portion of the center block in the rabbet B. The outer portions of these slips are slotted at c, to receive the neck of a screw, b, which is inserted in each leg, above the pivotal point thereof, and somewhat above the center block, when the leg is in line therewith. When the legs are unfolded they stand oblique to each other, crossing at the center block, and in this position the slip-braces D are horizontal, holding the legs firmly together, and to the upper portion of the center block. The upper ends of these legs are notched at e in their inner edges, as shown, the upper sides of said notches formin g a species of hook or clamp for the beveled rim of the top E, to receive the rounded and somewhat angular edge of the plane table-top E, which is cut somewhat large for fitting between the notches, so that when sprung into the same the elasticity of the legs will be exerted to cause them to close upon the bevel edge g,'forming atightjoint with said notches, and hold the top securely, they in turn being firmly held in proper position by their pivots a and the. brace-slips D. These brace-slips, being seated in the rabbets of the center block, and being of less thickness than the depth thereof, form no obstruction in the folding and unfolding of the legs, and when the legs are unfolded in their crossed or standing position these brace-slips extend in the shortest and most direct lines between their bearing-screws b and d, and rest upon the shoulder of the rabbet when the legs are extended, thereby preventing said links from passing below a horizontal line, thus placing the legs, when fully extended, in the exact position to bring their upper ends far enough apart, that the table-top must be sprunginto the notches in the legs, whereby the top is firmly-held from falling out of said notches when the table is moved or accidentally tipped over, so that the center joint of the table is made firm and secure, holding the legs at this point, so that when the top E is pressed into place in the notches of the legs their elasticity must be exerted and the edge of the top grasped, as above referred to.

The chains shown in the drawings are respectively attached to the legs, as represented, and serve not only the purpose of ornamentation, but also as safety-chainsin case the slot- 5 ted braces give way, and as loops for hanging the folded legs upon a hook or nail, when dewhen the legs are extended, and the top E, sirable. having beveled edges, to engage with said I am aware that the slotted brace-links and hook-notches when the table is set up for use, 1 prismatic center block are not my invention, substantially as specified and shown.
