EXTENSION-TABLE.

SPECIFICATION forming part of Letters lPatent No. 595,192, dated December 7, 1897.

Application filed July 19, 1897.

To all whom it may concern:

Be it known that I, SYLVESTER L. MCAD- AMS, a citizen of the United States, residing at Beaver Falls, in the county of Beaver and i tate of Pennsylvania, have invented certain new and useful Improvements in Extension- Tables; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, andto the letters of reference marked thereon, which form a part of this specification.

Figure 1 is a side View showing a table having my improvements with its parts in closed position. Fig. 2 is a top plan view. Fig. 3 is a top plan view of the table when the extensible parts are in their outer positions, the supplemental leaves on one side being shown in operative position and those on the other side being shown still in their folded position. Fig. 4 is a longitudinal section of Fig. 3. Fig. 5 is a transverse section on the line 3 y of Fig. 3. Fig. 6 is a transverse section on the line a of Fig. 3.

In the drawings the table is shown, which, as concerns many of its parts, is of substantially the ordinary character, these being such as the central or relatively stationary legs A A and the central or relatively stationary section at B.

0 indicates as a whole one of the extensible parts of the table, and 0 indicates the other. These are constructed substantially similarly, and each is provided with one or more movable legs D D.

The central or body part of the table consists, in addition to the aforesaid legs A A, of the top side frame'pieces E E and the top board F.

As the extensible sections O O are substantially similar, a description of one will be sufficient. Referring to that indicated by C, it will be seen to consist of an end top framepiece G and two relatively short side pieces H H and a top edge piece I. The side pieces H H are on lines immediately inside of the line on the main side pieces E E and are adapted to slide longitudinally relatively thereto. At their inner ends they are bound Serial No. 645,068. (No model.)

or pressed together by cross-bar J. To the inner sides of these side pieces II II are socured the inward-projecting cleat-bars or guide-bars K. The latter have a sliding con nection with bars L, each bar K and its companion bar L being joined by a tongueandgroove connection, so that longitudinal movement is permitted. 7

The part O of the table also has short side bars H H immediately inside of the main side bars E E, and they are joined together by a bottom crossbar J.

At j j there are stops, which, by engaging with the cross-bars J or J, limit the movement of the sliding guide-bars K and L.

Of such bars as those indicated at K and L as many will be employed as are necessary to provide the desired length of table.

M indicates a supporting-bar which, as shown, is secured to the inner bars L. Of such bars there can be as many employed as are necessary to support the required number of leaves, and the parts can be so an ranged that in some cases this supportingbar M or one or more thereof can be carried by the bar K.

Each folding leaf is constructed and ar ranged as follows: N N are two leaf-sections, the section N being preferably a little longer than the section N. They can be formed by dividing one sufficiently long leaf-board, the plane of separation or out being preferable, as shownthat is, inclined to the vertical for a purpose that will appear. These sections N N are hinged together by one or more links O 0, there being two in the construction shown, one at each edge of the leaf, and the latter may be countersunk sufficiently to have the links flush with the edges, so that there shall be no openings in the table-sun face. The links and the leaf-sections are so arranged that the section N can be turned over upon the top of the section N, so that it can be oppositely moved and brought down to have its inner end rest snugly against the inner end of the section N. By reason of the chamfered or beveled form of the contacting ends of these sections N N a firm support is given to the inner end of the section N through the links and through the sloping part of the section N. The section N is connected to the framework by a parallel-rule jointthat is to say, by two links P P, which are suitably pivoted to the bottom cross-bar M, as by pivots n, passing through cleats m. The links P are of such length and are so situated that when the leaf-section N is on the top section N both the latter can be moved inward and downward until they come to rest upon the bar M or the cleats m, and at such time they are entirely below the horizontal plane of the top boards F and I.

WVhen it is desired to extend or elongate the table, it is merely necessary to draw out one or both of the sections 0 C and lift up on the leaf-sections N N, whereupon the latter are moved forward and laterally under the guidance of the links P P until the outer end of the section N has passed over and come to rest upon the side bar II. Then the other leaf-section N is turned upon the hinges O O and brought so as to rest upon the other edge of bar ll. lVhen they are in these positions, the links P P, as will be seen, are inclined in the direction of leaf-section N, and a firm lock is provided by means of the links P P, the bars H H, the links 0 O, and the beveled or chamfered edges of the leaf-sections. To further increase the fastening, use may be made of dowel-pins Q and pin-apertures q.

The sliding and guiding framework forming the interior part of the other extensible section 0 has one or more bars R, which are inside of those at K and L, but which correspond in function, serving as means for connecting the sliding parts together and also as means for carrying one or more supportingbars, similar to that at M, for holding the folding leaves.

That I claim is- 1. In an extension-table, the combination with the main or relatively stationary frame, of the extension-frame sliding laterally from the main frame and having a supporting-bar, M, and an extension-leaf formed in two sections, N, N, the section N being connected to the support M by a parallel-rule joint, and the section l being connected to the section N by one or more links, the ends of the sections being beveled; substantially as set forth.

2. In an extension-table, the combination with the relatively stationary body part, of the laterally-adjustable extension-board, it having a support as at M, and an extensionleaf formed in two sections, N, N, hinged together at adjacent ends, means for rigidly supporting the inner end of one section upon the inner end of the other, and a parallelrule joint connecting the section N to the supporting-bar M, whereby the leaf-sections are movable to and from each other on planes transverse to the table, and the leaf, as a whole, is movable both transversely and vertically of the table in the same planes; substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
