COLLAPSIBL E L EAF FOR EXTENSION-TABLES.

SPECIFICATION forming part of Letters Patent No. 716,238, dated December 16, 1902.

Application filed April 28, 1902.

Jo all whom, it may concern.-

Be it known that I, HENR'YJOHNSON, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Collapsible Leaves for Extension-Tables, ofiwhioh the following 'is a specification, reference beinghad therein to the accompanying drawings.

The invention relates to extension-tables of that general typein which the leaves when table.

. been devised in which an absolutely uniform width is maintained.

With the present invention the objection is entirely overcome; and the invention consists, broadly, in the construction of a leaf adapted to be collapsed so as to diminish its width and to permit of readily storing the same within the stationary portion of the table.

The invention further consists in the peculiar construction as hereinafter described and claimed.

In the drawings, Figure 1 is a perspective.

View of a table partly broken away to show the leaves stored therein. Fig. 2 is a plan View showing the table extended. Fig. 3 is a perspective view of one of the leaves in collapsed position. Fig. 4 is a horizontal section through the leaf, showing the construction of joint between the sections thereof. Fig. 5 is a cross-section of the table.

A is a table, which maybe of anysuitable construction, adapted to have the leaves stored therein wh'en not in use. As shown, this table is provided with a round or oval top; but my improvements are equally ap plicable to tables of the square type. i

B represents the extension-leaves. Each of these leaves is divided transversely there- SerialNo.104,986. (No model.)

of or longitudinally ofthe table into two sections a and b. The joint between these sections is such that in position for use they are held in alinement with each other and form a continuous leaf extending for thefull width of the table. The sections are, however, capable of movement in. relation to each other, so that when they are to be stored they may be moved inward, thus diminishing the width of the leaf.

In the construction which is preferably employed and which is shown in the drawings the line of division between the sections a and b is inclined to the longitudinal axis of the table and the adjacent edges of said sections are slidingly joined to each other. This sliding joint may be formed, as shown, by providing the edge of one of the sections with a dovetail tenon or tongue 0, while the edge of the opposite section is provided with a I corresponding dovetail groove 01. The

.two sections may be engaged with each other by sliding the tongue into the groove. When the sections are inexact alinement, the width of the leaf is extended to be equal or greater than that of the table-top; but

when moved into the position shown in Fig.

3 the width is diminished to permit of storing. In order to limit the amount of lateral movement of the sections in relation to each other and to prevent accidental disengagement thereof, a stop is preferably provided. This, as shown in Fig. 4, may be formed by cutting away a section of the tongue, as indicated at e. f is a pin secured in the grooved section of the leaf and passing through the cut-away portion 6. This pin is so located that it will form a stop'to prevent the movement of the sections to extend the'same beextended position will rest upon said slides and will support the leaf at the exact plane of the table-top, as shown in Fig. 5. To hold the leaves in engagement with the stationary table-top, they may be provided with the usual dowel-pins and sockets.

What I claim as my invention is-- 1. Atable-leaf formed in two sections secured together, and means whereby said sections are relatively adjustable in the same plane.

2. A table-leaf formed in two sections secured to each other and means whereby said leaves are relatively adjustable in the same plane in a direction to contract or extend the width of the leaf.

3. In an extension-table, a leaf severed in an inclined line into two sections having their adjoining edges slidingly secured to each other for the purpose described.

4. A table-leaf comprising two complemen- HENRY JOHNSON.
