FOLDlNG COLLAPSIBLE TABLE, CHAIR, 80C.

SPECIFICATION forming part of Letters Patent No. 666,017, dated January 15 1901.

Application filed May 5, 1900- Serial No. 15,660. (No model.)

To all whom it may concern:

Be it known that I, FRITZ MACK, a subject of the German Emperor, residing at Nuremberg, Bavaria, Empire of Germany, have invented certain new and useful Improvements in Folding Tables or the Like, of which the following is a specification.

This invention has for its object to provide an improved folding or collapsible device as a support for tables, chairs, and like articles; and it consists in the employment of lazytongs arranged to form a collapsible, angular, or three-legged support, as hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a side elevation of a table embodying my invention. Fig. 2 is adetail viewof the stretcher for holding the lazy-tongs in a distended position; Fig. 3, a side elevation of said table collapsed; Fig. 4, a sectional plan view on the line 4 4 of Fig. l of the legs or support detached; Fig. 5, a top plan view of said table collapsed with the legs and stretcher in dotted lines. Figs. 6 and 7 represent a modification, and Fig. 8 a section thereof on the line 8 8 of Fig. 7.

First describing the invention as applied in the form of a three-legged support and as depicted in the first five figures of the draw ings, A indicates a table-top which may stand as an exponent for any suitable structure to be supported, and a, b, and 0 represent three sets of lazy-tongs arranged in intersecting vertical planes, so as to radiate from each other as a tripodal support. The inner upper arms a b c of these lazy-tongs are mutually interconnected by hinge-joints through a casting B, which is firmly secured to the table, while the outer upper arms a b c are free for slip-contact with the under side of the table.

In order to hold the lazy-tongs properly extended, a suitable stretcher d is employed, which is hingingly secured to any appropriate joint of the lazy-tongs or to one of the knuckles d of a series interconnecting the insetting-joints of said lazy-tongs and may be clamped between distended members of the lazy-tongsas, for instance, by a counter-hook d taking over an opposing knuckle.

Suitable feet e f g are arranged on the three outer lower arms of the lazy-tongs, the corresponding inner arms thereof being advisably' interconnected by a knuckle, as aforesaid, somewhat above the plane of the feet.

In Figs. 6, 7, and SI have shown an arrangement adapted to use with oblong or rectangular tables A or other articles requiring Widely-separated supports. Herein two pairs of lazy-tongs h and 'i, arranged divergently in intersecting vertical planes and interconnected at their inner joints along the line of intersection by knuckles jand to the table by a'knuckle-block j, are employed, one pair at each end ofthe table. Stretchers 7t and one for each pair, similar to the stretcher employed with the above-described tripodal set, serve to hold the lazy-tongs distended, the tongs being readily collapsible when said stretchers are released.

I claim 1. The combination with a table or like article, of a support therefor comprising lazytongs arranged in divergent planes intersecting each other with their insetting joints hingingly interconnected along the line of intersection, and a stretcher for holding said tongs distended.

2. The combination with a table or like article, of a tripodal support therefor, comprising three sets of lazy-tongs set radiatingly from each other with their insetting joints hingingly interconnected, and a stretcher hinged to one of the joints and adapted to be clamped to an opposing joint.

3. The combination of the table, the angularly-arranged lazy-tongs, the knuckles interconnecting the insetting joints of said lazytongs, and the stretcher hinged to one of said knuckles and provided with a counter-hook to take over an opposing knuckle.

In testimony whereof I aflix my signature in presence of two witnesses.

FRITZ MACK.
