EXTENSION TABLE Applicationbfiled October 15,1928. Serial No. 312,732.

invention-relates to improvements in tables, and particularly to extension tables,

It is one of theobjects of my invention to provide an extension table wherein theextension leaves thereof may bemoved from one positionto another with a minimum of effort.

A further object of myinvention is to provide an extension table of the above type wherein the extension leaves are mounted on: slides to permit the leaves to be moved into and out of position and to provide means for-readily raising the leaves as they have been moved to their outer position to bring the same to the tabletop vlevel and for lowering the leavesto per-mitthe leaves tobe slid underthe-table top for storage. v

- Forthe .purposeof disclosingmy invention I have illustrated one embodiment thereof in K the accompanying drawings inrwhich Fig. 1

is a bottom plan, with the legs, of a table em bodyingmy invention; Fig. 2 is a longitudinal 'sectionalview showing the leaves and table top lying in the same plane preparatory to beingmoved to interlocking position; F ig.*3 is a view similar to Fig. 2 showing the leaves and table top;moved'into interlocking f position; Fig. 4 is a. similar view showing the leaves in extended position and moved to aplane below the table top for movement to storage position; Fig. 5 is a similarrview showing the leaves Imoved to their storage position beneath the table top F ig, 6 is a plan a partly" broken awayto show the table leaf I slides, and Fig. 7 a transverse detailed section of the leaf slides.

In the embodiment of the invention illus trated I provide a suitable support or base comprising transversely extendlng bars 1 and longitudinally extending bars 2forming a. rectangular-frame. J This framemay be I 'mounted on a table pedestal or may he secured-to table legs or if desired, anygother.v

. type of support may be provided. The table top-3 and the extension leaves 4 and-5 are vertically movable relatively to one another,

and to the base or support, leaves being mounted on suitable slides to permit the same to be moved from storage to extension position and vice versa. To this end each leaf is provided with a pair of movable slides '50. 6,on which the leaf is mounted. These movable slides cooperate I with. relatively stationary slides 7 The opposite slides of each leaf are provided with suitable racks 8 and 9 geared together by means of a pinion 10-165 mounted on the stationary slide. so that the. moving slides of the two leaves will operate in unison whereby when one leaf is moved the corresponding leaf will partake of the same movement; o '51;

In order that there maybe a vertical relative movement of the table top and the leaves, a

I provide two pairs oflevers, one onteach side of the table and asieach pairis similar, it will only be necessary to describe one pair. 135 Each pair comprises two levers 11 and 12, each of which is pivotally mounted on a fulcrum ear 13 in turn,stationarily mounted on the base or support. The inner. ends of the levers are pivotally connected as at 14v to -'5? cause the levers to move in unison'and on one side of the fulcrum memberl3 eachlever is pivotallyconnectedas a-t15 tea downwardly 5 extending ear 16- mounted on the under face 7 of the table top. The opposite end of the lever 11 is pivotallyconnected to an upwardly extending; ear 17 mounted. on a transverse bar 18 extendingbetweenthe stationary slides .7 and the opposite end of the lever 12 is similarly connected toan ear 19 on .a sta-' sctionary bar 20 likewise extending between and connected to the stationary slides 7.

"The table top at its opposite ends is provided with shoulders 21. which are adapted toainterlock with overhanging shoulders 22 on theleaves. v

With the above construction and the parts in the position illustrated in Fig. 5, that is,

with the leaves in their retracted. and stor' agepositionbeneath the table top,'in order 9 to extend the leaves it is merely necessary to pull on one or the other of the leaves. This will cause the two leaves to move to the position illustrated in Fig. 4. With the parts 5 in this position, in order to bring the leaves 4 and 5 into the same plane as that of the table top, the table top is depressed by a slight pressure, thus rocking the inner ends of the levers downwardly and causing the outer 0 ends of the levers to rise, thereby raising the leaf slides as a unit until the parts assume the position illustrated in Fig. 2, after which the leaves may be moved towards the table top until the shoulders 21 and 22 interlock 5 to prevent relative vertical movement between the leaves and the table tops.

With the leaves in their extended position as illustrated in Fig. 3, in order to move the leaves back through their storage position,

0 it is of course merely necessary to move the leaves to a further extended position as illustrated in Fig. 2, after which they may be depressed by a slight pressure on either one, which pressure will rock the levers or fulcrums, lowering the leaves and at the same time raising the table top until the parts assume the position illustrated in Fig. 4, after which the leaves may be slid to their storage position beneath the table top as shown in It is apparent from the above that the leaves and table top have a relative right line movement and that each is movable relatively to the other. It is further apparent that both the table top and the leaves are vertically movable with a right line movement respectively to the stationary base or support.

The above construction permits of an extremely simple mounting for the parts and 0 permits of the operation of the parts without binding and with a minimum effort on the part of the operator.

I claim as my invention:

1. The combination with a suitable sup- 5 port, two pairs of levers fulcrumed on sa d support, the ends of each pair being pivotally connected, a table top supported by said levers on one side of their fulcrums, stationary extension leaf slides supported by the levers of each pair on the opposite side of their fulcrums, movable leaf slides supported by said stationary slides and extension leaves mounted on said movable slides.

2. As an article of manufacture, an extension table element comprising a central bracket adapted for attachment to the under side of the table leaf, two oppositely projected connected levers pivoted on said bracket, two brackets pivotally attached to each lever, one adapted for attachment to a base support and the other to an extensionleaf-slide-structure.

3. A table comprising a main-leaf structure, an extension-leaf structure, comprising 5 a slidable support for the extension leaf, and

a leaf supporting structure movably mounted on the main body of the table and connecting said main-leaf structure and the extension leaf structure whereby vertical move ment of either will cause opposite vertical movement of the other.

1. A table comprising a main-leaf structure, an extension-leaf structure comprising a slidable support for the extension leaf, and a supported lever system upon which the main-leaf structure and extension-leaf structure are mounted for opposite vertical movement.

5. A table comprising a base, a verticallymovable main-leaf, a leaf-supporting mechanism vertically movable on the base, an extension-leaf laterally slidable on said leafsupporting mechanism, connections between the main-leaf and said leaf-supporting mechanism to reversely transmit vertically applied force from one leaf to the other.

6. A table-top comprising a vertically movable main leaf, a vertically-movable slidesupport an extension-leaf carried by said slide, lever-supports, and levers carried by said supports and carrying the main-leaf and slide-support for simultaneous opposite vertical movement.
