Lette/rs Patent No. 88,132, dated March 23, 1869.

IMPROVED EXTENSION-TABLE.

The Schedule xefened to in these Letters Patent and making part o! the lama.

To all whom it may conce/m:

Beit known that I, GIACOMO GHELINI, of Washington city, county of NVashington, and in the District of Columbia, have invented a new and useful Improvement in Extension! ables; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l is a side elevation of the extension-table, shown in a contracted position.

Figure 2 is a side elevation of the extension-table, shown in an extended position.

Figure 3 is a transverse vertical position, on line :c as, 1. gFigure 4 is a side elevation of the extension-table, shown in a position in which it is extended to its utmost capacity.

Figure 5 is a plan view, in which some of the leaves of the extension-table are removed in order to show interior parts.

Figure 6 is a perspective view of the movable frame on which the intermediate leaves rest when the table is extended.

The letters of reference, where employed in the drawings, denote identical parts.

The nature of my invention consists in the construction and operation of a movable frame, attached to an extension-table, for the purpose of' supporting the intermediate leaves when the extension-table is extended.

To enable others skilled in the art to make and use my improvement, I will proceed to describe its operation and construction.

A and A are horizontal frames, of equal size, mounted on legs B B B B, and supporting the horizontal-sliding bars, on which the leaves rest when the table is contracted.

C C and D D are horizontal bars, permanently secured to the frames A and A.

The sliding bars E E serve to connect the bars D D and C C with each other; and iig. 3 shows a transverse vertical section on line :1: fig. 1, of all these parts, in a position where the table is contracted.

To keep the connecting-bars E E at their proper distance, and parallel to each other, and thereby securing a steady working, I employ a brace, F, secured at the under side of the ,bars E and E.

To prevent the connecting sliding bars E E from being separated from the bars C C and D D, I fasten to the ends of the bars, a piece of sheet-metal, G G G G, bent at right angles, and serving also to keep the bars close together.

Fig. 5 shows these metal fastenings when drawn close together, and in such position that they will prevent the table from being further extended.

Fig. 3 shows a vertical section of above-mentioned stenings, and also how they are bent at their edges suiciently to extend downwards in vertical recesses cut for that purpose in the bars C C, D D, and E E.

The connecting-bars E E are at their upper side, provided with recesses, deep enough to contain movable frames I I.

Fig. '4 shows these movable frames in aposition when serving as a rest for the intermediate leaves.

When in such position, the leaves will be ona level with the end leaves of the table, and form one plane surface.

The legs of the movable frames t 'i a', t' are pivoted or hinged at theirlower ends to the connecting slidingv bars E E, at k c c k, and also pivoted or hinged at-their upper ends to bars I and I', at k 7c k' It'. Y

Fig. 6 shows a perspective view of the movable frame detached from the sliding bars E E.

To keep these movable supports I I in a vertical position, detents, or pawls K K are hinged at the under side of bars I and I, andare of vsufficient length to reach down into recesses cut for that purpose in the upper side of bars EE, at t".

The direction of the inclination ofthe detents in their respective movable frames, is reversed, in order to prevent the supports from giving way when a weight is placed on them, and neither a jerk nor a push can occasion said supports I I to fall from their vertical position, unless the detents are lifted from the recesses in which they are placed,l

The leaves H and H' are placed at the ends of the table, and immediately above the legs, and are hinged to the frames A and A', at h hi, in such a manner that they may be swung upward, and allow the leaves L L and L L to be folded out.

The leaves are either hinged together, as shown at l and l', (fig. 2,) or connected together )Vith pieces of India rubber, firmly secured in both adjoining leaves, as shown at h, fig. 2.

To secure such connection, buttons, or projections hl, may be supplied at one edge, and at the adjoining edge, recesses h, made to receive the projections h, and the leaves may be folded upward or downward, as found most convenient.

I do not confine myself to the use of only two connecting sliding bars, and ve or more legs may also be used to advantage, where a larger number of leaves is employed.

When the table is contracted, I fasten the two frames A and A together, by clasps or hooks M M, and when thus fastened, the table may be moved about without beingseparated.

The small leaves, N andN', which form the ends of the table, are hinged to the leaves H and H', and kept in a horizontal position by the supports O and O. Said supports are hinged at their upper end to the inner side of the leaves N and N at n n', and their lowr ends'rest against the frames A and A', at n and n', g. 4.

In the end pieces of frames A and A', are vertical apertures P, wide enough to allow the supports O and 0 to pass through.

When the leuves N und N ure desired to occupy a In testimony whereof', I have signed my name to this vertical position, the supports O and O' are put through specification, in the presence of two subscribing Witthe apertures P P, and will slide under the table. nesses.

Having thus described my invention, GIACOMO GHELINI.

VVlmt I claim, and desire to `Secure by Letters Petent. iS Witnesses:
