EXTENSION-TABLE.

SPECIFICATION forming part of Letters Patent No. 361,688, dated April 26, 1887.

Application filed February 7, 1887. Serial No. 226,772.

To @ZZ whom it may concern:

Be it known that I, CHARLES G-EBHARDT, a citizen of the United States of America, residing at Cabery, in the county of Kankakee and State of Illinois, have invented certain new and useful Improvements in Extension-Tables, of which the following is a specilication, reference being had therein to the accompanying drawings.

This invention relates to cert-ain improve- .ments in extension-tables, the construction and operation of which is fully set forth and explained in the following Aspecification and claims, reference being had to the accompanying drawings, and the letters and figures of reference thereon, making a part of this specification, in which- Figure 1 is a perspective view of the table as it would appear closed, showing the free leaf below the head-leaves, which are closed over it. Fig. 2 is a side elevation of the table, showing it extended. Fig. 3 is a bottom plan view of the table. Fig. 4 is-a central longitudinal vertical section of the table. Fig. 5 is a central vertical cross-section of the table; and Fig. 6 is a central cross-sectional view of `the free leaf, showing one of its cleats and the cross-bars of the frame supportingsaid leaf, the dotted lines showing the reverse position. Referring to the drawings, L represents the legs of the table supporting the endframes, D, and the side frames, D2, the said side frames being in two equal parts, so they may be separable.

G G are cross-bars connecting, respectively, the inner ends of the side frames, D2, and support the central part of the extension-slides S in a recess in said cross-bars, as shown in Figs. 5 and 6. The endframes, D D', are connected with each other through the medium of said extension-slides, as shown in Figs. 3 and 4, to connect the two parts of the table.

D D are boards secured to the table-frame above the end frames, D D', as shown in Figs. 1, 2, and 4, and B B are head-leaves secured to said boards by means of hinges H H, as shown in Fig. 4. E E are drop-leaves hinged to said head-leaves in the usual manner. The two head-leaves B B are adapted t-o be elevated at their meeting edges, as shown in dotted lines in Fig. 4, and are held down by means (No model.)

of the coil-springs Z, connecting them with the frame D', the said boards D D being provided with apertures J J, through which said springs pass to permit such connection.

C is a free leaf, having secured to its llower side the cleats FF, one at either end, as shown in Figs. 3, 4, 5, and 6,which rest on the crossbars G G, in notches cut therein, and properly support said free leaf, .and are provided with depending hooks R R at each end, as shown in Figs. 4 and 6, to hook over said cross-bars and preventthem from becoming disengaged from said cross-bars when the table is extended. (See Figs. 2, 3, and 4.) Said cleats are thicker at their ends than at their central part, and are each formed with an inclined portion at each end, as shown at V V in Fig. 6, and in Figs. 2 and 4, so as to support the free leaf on the same plane with the head-leaves B B when the table is extended and the cross-bars G G separated, and on a plane below said headleaves when the table is closed, so said headleaves may close over said free leaf. When the table is extended, as shown in Figs. 2, 3, and 4, said inclines will ride upon said crossbars until the cleats F rest at each end on a cross-bar, G, as shown in Figs. 2 and 4, and thus elevate said free leaf C to the same plane of the head-leaves B B, and between them. The normal position of said free leaf is under said head-leaves, as shown in Fig. l, which position is permitted by means of said cleats resting at their center, where they are narrowest, on the cross-bars G G, as shown in the full lines in Fig. 6. When the table is being extended, the free leaf C is gradually elevated by means of its inclined cleats riding on said cross-bars G, and thereby elevates the headleaves B B, as shown in dotted lines in Fig. 4, until said head-leaves drop at each side ofthe free leaf C, as shown in full lines in said ligure. Said leaves are then closed together and held in proper place by means of dowel-pins, in the usual manner. IVhen it is desired to collapse f ported on said cross-bars-G G, as shown in Figs. 1 and 6.

' The extensionslides S consist of wooden Figs. 2, 3, 4, and 5, and permitthe said bars to be extended. Each end section of said eX- tension slides S is securely Xed to its respective part of the table by means of cornerblocks glned therein, and other suitable fastenings, and the central-sections, having the three pin-bearings vand a double pin-bearing in the slot of each end section, thus form av very strong and durable slide. (See Figs. 3 and 4.)

d d are a pair of molding-strips, secured to one side frame on each side of the table in such manner as to properly cover the joint of said side frames when the table is collapsed.

In arranging the springs Z they are given sufficient tension to yieldingly but quite firmly hold said head-leaves down upon the boards D,

to which they are hinged, so that the tabletop will, when either extended or collapsed, be horizontal and level; but the yielding qualities of said springs permit said headleaves to be raised, as described, when it is desired to adj ust the table.

The purpose of the boards D D is to support the head-leaves B B above the table-frame, so that room is made between said head-leaves and the table-frame for the free leaf C when the table is collapsed.

In order to prevent the head-leaves from' warping, they may be provided with dovetail cleats, as shown at yin Figs. 3 and 5.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent is as follows, to wit:

l. In the extension table shown and described, the combination of the separable crossbars G G, free leaf C, and inclined cleats F F, having the depending hooks R R, as and for the purpose Set forth.

2. In the extension table shown and described, t-he co mbination of the separable crossbars G G, free leaf C, inclined cleats F F, having the depending hooks R R, extension-slides S S, and head-leaves B B, substantially as and for the purpose set forth.
