a .3 Claims. )(01. 45-112) The present invention relates to a table construction and-in particular to a table having drop leaves which may be enlargedto a-considerable size. v

I In the table of the present-invention, the top may assume in general, three positions. A position in which the drop leaves hang over the side of the table which might be called position A; the second position in which the drop leaves are flush with the table top but turned at right angles to the first position, which may be called position B and a third position, position in which the table may be extended for the insertion of additional leaves, this position being an extension of position B.

In the present invention the construction for accomplishing the results just described is obtained in such a manner that the table in any of its positions is not only firm and strong, but can be handled with considerable ease by one person in adjusting it to any of the desired positions mentioned above. The construction is accomplished in combination with a specially designed method of support in which, as will be noted later, 25 the feet do not extend beyond or substantially beyond the limits of the table top in the initial position A. The table in its construction is provided with a plurality of supporting feet which support the table top at its center, which is also the point about which the table top may be rotated. The construction and features of the present invention andtheir advantages over other constructions will be better understood by a consideration of the description given below in connection with the drawings illustrating an embodiment of the invention, in which:

Figure 1 shows the table in position A. Figure 2 shows the table in position B.. Figure 3 shows the table in position C. Figure 4 is a detail View looking down on the center of the table shown in Figure 1, the top leaves being omitted.

Figure 4a is a perspective view of the pivoting wings as they appear in Figs. 1, 4 and 5.

Figure 5 is a fragmentary vertical section of the top in position A and is taken on the line 5-5 ofFig.1.' v

Figure 6 is a detail view looking up at the center of the table shown in Fig. 2.

Fig. 8 is a perspective view of the as they appear in Figs. 2, 6 and 7.

Fig. 9 is a fragmentary vertical section of the pivoting wings top in position C of Fig. 3.

Figure 10 is a bottom view of Fig. 9 but omits the center leaves and shows the wings only slightly separated.

Figure 10a shows Figures 9 and 10.

Figure 11 shows a top view of the table with the top removed in a position corresponding to position B, and,

Figure 12 shows a section taken on the line 12-12 of Figure 11 with the top in place.

In Figure 1 as indicated there is provided four arched supporting legs, 1, 2, 3 and 4 which support a center beam or pedestal 5, from which there may extend supporting elements 6, 7, 8 and 9 extending to the supporting beams 10 and 11 running lengthwise to the leg positions indicated in Figure 12. The pedestal 5 may be carried upward beyond the supporting elements 6, 7, 8 and 9, and may support a fiat beam 80, extending lengthwise at the center of the table. The beams 10 and 11 are joined respectively along their length to the side support 10' and 11'. A beam 50 is mounted on and fixed to the beam 10 in the position shown in Figure 12 and a beam 51 is similarly mounted on the beam 11. This may be accomplished by means of screws 52, 52, or in any suitable manner. A train of gears 53, 53, 53, are pivoted centrally on the beam 50 and at both ends of the train are gears 54 and 55 respectively, the gear 54 meshing with a. rack 56 mounted on a slide rail 13 and the gear 55 meshing with a rack 57 mounted on a. slide rail 16. The rail 16 is connected to a slide rail 15 by a cross piece or bridge 17 and the rail 13 is connected to a slide rail 14 by a bridge element 18. As indicated by the arrows in Figure 11, the rails 15 and I6 move in one direction and the rails 13 and 14 in the opposite direction. One bridge element therefore moves with one pair of rails while the other moves in the opposite direction with the other pair of rails. As shown in Figure 1, a table board 19 with its drop leaf 21 is positioned lengthwise to the beam 10' and the rails while a table board 20 and its drop leaf 22 is similarly positioned with respect to the beam 11'. In this position the boards 19 and 20 and their drop leaves may not be moved longitudinally with respect to each other because of a conventional dowel pin connection between the boards 19 and 20. In the position as indicated in Figure 1 the leaf 19 is fastened by means of screws or nails to a wing 24 of a hardware element 23 and the board 20 is similarly fastened to a wing 25. The wing 24 is pivoted and is taken on the line 99 a perspective of the wings of m a wing 20 which is fastened to the bridge eleware element is shown more in detail in Figures 4 to 9 inclusive. It comprises two pair of wing elements 24 and 26, and 25 and 27 respectively. The element 24 is bent over at the small end 28 toa U shapedformhronesideofwhichascrew 29 may be threaded, the shank of the latter forming a. pivot for the wings 24 and 28. The wing 24 is attached to the table board while the wing 26,ashasbeenexplained,lsattachedto thebridge element 17. The pair of wing elements 25 and 27 are similarly joined so that they may pivot about ascrew30asshowninFigure'l.

It will be noted in Figure 7, which shows the table top boards together and in an unextended position but with the drop leaf across the supporting beams, that the screws 29 and 30 are positioned one above the other. It should also be the table as shown in Pig. 2. when the leaves are in this position, the hardware element is in the positionshowninrigurefl. Itwillbeseenthatin this position the table may be extended by separating the leaves 19 and 20 and the two pair of pivot elements. This is indicated in Figures 3 and 9. Additional leaves 82, 33, 34 and 35, which are showninl iguresmavthenbeinserted.

Having now described my invention, I claim:

1. A drop leaf table of the type described comprising a plurality of supporting legs, a plurality of parallel beams supported thereby, a plurality of frames supported by said beams, means for adjustably moving said frames with respect to one another and the beams, two groups of table leaves, means attaching said groups to said frames, said means including a pair of pivotally connected members for each group, the pivotal axis of one pair lying directly above the axis of the other pair when .one group of leaves abuts the other noted that the edge of the boards pass through grou the line of this pivot. In this way when the boards are together and only when they are together can the top be turned. This will appear more clearly later. In the position of the table shown in Figure 1, the hardware element 23 assumes the positionshowninFigures4,4aand5. Inthiscase the abutting edges of leaves 19 and 20 are perpendicular to the longitudinal axes of the bridge elements 1'? and 18, the leaves 19 and 20 bei attached to the wing elements 24 and 25, respectively, by nails or screws. The line joining the boards 19 and 20 is indicated by the line 31 in the figure and as is notedpasses through the center of the pivot of each pair of wing elements.

When the drop leaves 21 and 22 are raised to a horizontal position, the leaves 19 and 20 and the drop leaves may be rotated about the center pivot, the leaves sliding on the upper faces of the beams 50 and 51 and assuming a position across 2. A drop leaf table of the type described havinga table top comprising two groups or leaves, each group comprising a main leaf and a drop leaf, the main leaves meeting at a center line of the table, two frames adjacent the center of the table, means pivotally connecting each group to its corresponding frame whereby the leaves may be turned from a lengthwise to a transverse position, and means to support the frames for separating movement to extend the table.

3. In a drop leaf extension table, a pivot comprising a pair of flat plates broad at one end and tapered at the other to a narrow end, one of the plates at the small end bent in a U shape about the small end of the other plate and a shaft passin]: through the U shaped portion and the other P te.
