EXTENSION-TABLE.

SPECIFICATION forming part of Letters Patent No. 316,472, dated April 28, 1885.

Application filed June 18, 1884.

T0 aZZ whom it may concern.-

Be it known that I, Josnua D. DLIAIN, of the city of Springfield, county of Clark, and State of Ohio, have invented certain new and useful Improvements in Extension-Tables, of which the following is a specification.

This invention relates to extension-tables, and is especially intended as an improvement upon that class wherein the legs are made removable.

The object of my invention is to provide an extension-table which will be cheap and durable in construction, and in which the extension-rails or slide-bars will be connect ed directly with and slide in the side rails of the table, said side rails forming a part thereof, thereby providing a bearing for the leaves of the table in close proximity to their ends; also, to so construct the legs of the said table that they may be easily removed and replaced, which is of great convenience in shipping, 860.

Figure 1 represents an under side sectional view on dotted line at as, Fig. 2, of an extension-table made in accordance with my invention, the side rails being herein shown on a line with one another and provided with supplemental extension-rails; Fig. 2, a side elevation ofthe same, partially in section; Fig. 3, an enlarged detail of the clamping mechanism for holding the legs in place; Fig. 4, a detail ofthe side rails and corner-posts, the said rails being herein shown as overlapped and connected directly with one another; and Fig. 5 is a section on dotted line 3 y, Fig. 1, of the extension 'rails.

The table-top, of any desired construction is composed, as usual, of two main sections, A A, andleaves B.

Attached to the under side of the tabletop sections A A are corner-posts 0, said corner-posts being connected together by end rails, D D, side rails, D D and supple mental extension-rails D D D, the said side rails and supplemental extension-rails being herein shown as connected together by means of tongues and grooves. The extension-rails D D are connected together by means of a cross-bar, E, said crossbar E having an opening at its center for the reception of the center leg, F, of the table. The corner-posts O are bored out to form a recess to receive (No model.)

round tenons or dowel-pins G on the legs H,

extensiontable-say an eight-foot table-the side rails, D D", will be made, as shown in Fig. 4:, to overlap one another, thereby d0- ing away with the supplemental extensionrails D D D", the corner posts 0 being in such case recessed to form an opening for the reception of the opposite side rails. This, as will be noticed, forms a very simple and con venient extension, and there being no joint or scam in the center of the side rails when the table is closed adds materially to the ornamentation.

By the construction herein described a bearing is formed for the leaves of the table in close proximity to their ends, which is a great desideratum, as it insures a greater rigidity of parts than if as heretofore constructed, the extension in tables of usual constructionbeing near the center of the table.

I claim- In an extension table, the combination, with the corner-posts and removable legs, of the clamping device for holding the legs in place, consisting of the binding post 1, secured to the corner-posts, the spring-clamp K, having the elongated slot J, said springclamp being adapted to engage with the leg, as described,and the thumb-nut 1* to regulate the tension of the spring-clamp, substantially as described.

In witness whereof I have hereunto set my hand and seal, at Springfield, Ohio, this 8th day of June, A. D. 1884.

JOSHUA D. MAIN.
