FOLDING TABLE.

Application filedA September This invention relates to extension tables and pertains more particularly to a slide structure upon which two permanent table tops are mounted and are adapted to abut when a narrow table top is desired and to be slid apart in order that an extension leaf may be inserted between them.

rlhe main object oit the invention is to provideaI structure for the above mentioned purpose whereby the table legs will at all times remain stationary on the vfloor and that when a pulling strain is exerted on one side oit the table top the other side oit the table top will move zin-equal distance in the opposite direction, thereby extending` the table top to project an equal distance beyond the table legs, thus balancing the overhang.

The above and other objects of the inven tion will be more fully disclosed in the fol lowing specification and will be exemplilied in the accompanying drawings in which:

Figure 1 is a side view of a table showing the invention as it would appear when appliedy thereto, the legs of the table being broken oil.

Figure 2 is an end view ol: the same.

Figure 3 is an enlarged plan view of the slide structure forming the invention, as it would appear when in a contracted position.

Figure 4: is a similar View tothat of Figure 3 as it would appear when partially extended.

Figure 5 is an end view oli the slide struce ture.

In carrying out the invention 8 and 9 repn resent slide structures which are spaced a desired distance apart in parallel relation. The slide structures are identical in construction and each one comprises a base rail 10 and each base rail is supported by a pair of table legs 11 and 12.

The banse rail 10 is provided with oppositely disposed guideways 13 and 141 which are parallel with each other and mounted to slide in said guideways are the

slide bars

15 and 16.

A lever 17 is pivotedy to the base rail 10 at 18, the ends of said lever extending equally beyond the pivoted point 1S and said pivoted point being located approximately midway between the ends and sides oit the base rail and between the slide bars 15 and 1G 7, 1927. Serial NO. 218,000.

as clearly shown in Figure 8 of the drawn ings.

Links 19 and 2O are pivoted respectively to the

slide bars

15 and 16 at 21 and 22, the opposite ends of said links being pivotcd respectively at 23 and 24; to the ends of the lever 17.

Each of the slide bars 15 and 1G is provided with raised portions 25 and 2b respectively upon which the table leaves 27 and 28 are secured7 the leali, 27 being secured to the raised portions of the extension arms 15 of structures 8 and 9 and the leale Q8 being secured to the raised portions of the extension arms 1G.

.By the above recited construction, it will be obvious that when either of the table .leaves 27 or 2S is pulled outwardly the other table leaf will be caused to move outwardly in the opposite direction an equal distance to that of the manually moved leaf, and then a loose table leaf (not shown) may be insorted between the

separated leaves

27 or 28 to provide an enlarged table top. This movement is accomplished by reason of the lever and link connection between the two

slide bars

15 and 16.

Having thus described my invention what I claim is:

1. An extension table structure comprising a rail; a pair of slide bars mounted on said rail and slidable longitudinally thereof; a lever pivoted intermediate its ends on said rail and link connections between the ends ol. said lever and said slide bars.

2. An extension table structure comprising` a rail; a pair of slide bars mounted on said rail in longitudinal grooves formed therein and a lever pivoted intermediate its ends on said rail to form oppositely disposed arms one of said arms being connected to one oi? said slide bars and the otheroit Asaid arms being connected to the other slide bar.

3. An extension table structure comprising a rail provided with apair of 1parallel guideways spaced apart7 said guideways extending longitudinally of said rail; slide bars mounted in said guideways; a lever pivoted to said "ail intermediate its ends to Yterm oppositely disposed arms the pivotal point on said rail being` located approximately midway between the slide bars and the ends o'l' said rail and one of said arms being` connected to one of said slide bars'end the other of said arms being connected to the other slide ber.

il. An extensiontable Comprising a rail at each side thereof, e pair of slide bers mounted on each of said rails and slidztble longitudinally thereof, a, lever pivoted intermediate its ends on each of said rails7 and link 10 Connections between the ends of said lever and the slide bars at that side of the table. In testimony whereof I hereunto ailix my signature'.
