EXTENSION-TABLE.

SPECIFICATION forming part of LettersPatentNo.422,599, dated March 4, 1890.

Application filed October 2, 1889- Serial No. 325,751. (No model.)

in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a perspective view of a table constructed in accordance with the invention, showing the sliding sections slightly drawn out. Fig. 2 is a reverse plan View. Fig. 3 is a longitudinal sectional view, and Fig. 4 is a detail sectional view.

Referring, to the accompanying drawings by letter, A designates the top of a table provided within a short distance of its edges with a rail a and consisting of a stationary central section A, to which the main legs B and B are pivoted, and two sliding sections A and A arranged at each side of the central section A, and having secured to them auxiliary legs 0 and C. The main legsconsist of a pair of outer legs B,which are pivoted to bars D, arranged transversely on the under side of the central section A, and a pair of inner legs B, which are connected by a central bar B whereby the legs are firmly and securely held t... r I

when spread to support the table Secured to the under sides of the central section A are T-shaped guide-strips F, which form ways for two pairs of L-shaped sliding strips G and G which are secured, respectively, to the sections A and A of the top of the table. These sliding Lshaped strips G and G are connected by cross pieces H and H, which are arranged near the front and rear ends to preserve the parallelism of the rails and to keep them in the grooves or Ways 1 f, and the pieces H have secured to them the auxiliary legs 0 and O, that are designed to be removed from the table when the latter is stored or being shipped. By this--construction an extension table is produced that is strong and solid and capable of being com pactly folded when desired. The outer sliding strips G are provided with lateral projections g, which engage the stop-blocks E and limit the movement of the sliding section A and the inner strips G have their cross-piece I-I arranged at their ends, and a stop-block I is secured to the edge of the central section A to limit the movement of the section A by engaging the cross-piece.

The sections A and A are provided with dowel-pins a, and the central section A has perforations a to receive the dowel-pins, and leaves are designed to be inserted between the sections in the well-known manner.

From the foregoing description and the accompan yin g'drawings the construction, operation, and advantages of the invention will readily be understood. The bars H H carry the auxiliary legs, and being secured in place by screws can be removed from the sliding sections so as to remove the legs. When the table is being shipped,the main section A folds down compactly, and the cross-bars H H with the auxiliary legs laid over the folding main legs, and the whole strapped or otherwise secured together. In six-foot extension-tables the auxiliary legs may be omitted; but they are essential when the table is greatly lengthened, as 011 a ten-foot table.

The construction of the central main section with the folding legs forms no part of the present invention, as it is embraced in an application for patent already on file inthe Patent Office, Serial No. 309,560, filed May 4, 1889,

What I claim is-- 1. The combination of the stationary section A, provided with the guidestrips, the stop blocks provided with pins, the block I, the outer pair of main legs pivoted to the section, the inner pair pivoted to the outer pair, and having perforations to engage said pins, the sliding sections provided with sliding ICQ strips, and the cross-pieces adapted to engage said block I, and the auxiliary legs secured to the sliding sections, substantially as described.

2. The combination of the section A, the T-shaped guide-strips, the stop-blocks E, pr0- vided with pins 0, the block I, the outer pair of main legs pivoted to the section, the inner pair pivoted to the outer ones and having perforations to engage said pins 6, the sections A and A the L-shaped sliding strips G, se-

cured to the section A and provided with lateral pro ections adapted to engage said my ownI have hereto aflixed my signature in 20 presence of two witnesses.
