IMPROVED EXTENSION-TABLE.

Sp ecication forming part of Letters Patent No. 91,099, dated June 8, 1869.

To all whom, t may concern:

. Be it known that I, JACOB DOURSON, of Columbus, in the county of Franklin and State of Ohio, have invented a new and useful Improvement in Fall-Leaf Extension-Tables; and I do hereby declare the following to -be a full, clear, and exact description of the same, suicient to enable others skilled in the art to which my invention appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specication, in which Figure 1 is a longitudinal central section of Fig. 2. Fig. 2 is aninverted plan view of my table when not extended. Fig. 3 is a detail View, to be hereinafter referred to.

The present invention is an improvement on the extension-table patented to me March 16, 1869.

-The object is to. so arrange or combine the slides that the frame of the table can be drawn out to such an extent as to render the auto- 1 matic supports unnecessary. The latter may of the slides,as hereinafter described, so as to permit the increased extension of the frame -k and adapt my improvement to extension-tables of large dimensions.

My invention will be fully understood by reference to the accompanying drawings, considered in connection with the following detail description.

Similar letters of reference indicate like parts in the several gures.

In the drawings, A represents the top of the table, and B B the leaves.

C C C C are the legs, of which the two on each side of the table are connected together by strips D, D. Y

E E are blocks secured immovably to the under side of the top A, and having longitudinal grooves in both sides to receive the projections of the metallic slides 2T, attached to the end pieces F F of the table-frame. The slides t' being fully described in my former patent, above referred to, a further speciiication of'them is deemed unnecessary here. y I

In my former patent the pieces F F, which are secured to the legs C C, are arranged on the outer sides of the fixed blocks E E. In the present case, as will be seen by referring to Fig. 2, the two pieces F at the same end of' strengthened, as before stated, by similar slides i, attached to the inner ends of the pieces F and tting in grooves in the stationary part E.

If it be desired to employ auxiliary supports for the leaves, either two, as in my former`patent, or one, as in this case, can be used. for each leaf. In the present case, G G

represent the auxiliary supports, which vare simply Wooden strips centrally pivoted to the upper sides of the parts D, and having longif `tudinal grooves in the upper side, which receive pins a, fixed in the top A of the table underneath. When the sides D of the frame are drawn out, the auxiliary supports are brought automatically to the position shown in red lines, Fig. 2. y

My improvement may be adapted to extension-tables of large dimensions by increasing the number of slides F F, as shown in redv lines, Fig. 3, and attaching the outer slides of t-he series to the legs of the table.

I-Iaving thus described my invention, what I claim as new, and desire to secure by Letters Patent, is;-

The arrangement of the slides F F, which are connected with the table-legs on oppositel sides of the blocks E, when the latter are attached to the tabletop A, and are connected with the parts F F by means of the metallic slides il t, all constructed and arranged to operate substantially as described, and for the purpose speciiied.

To the above I have signed my name this 27th day of March, 1869. l
