I .a mu T. a N W m5 M a m E A TTORNEYS Patented Oct. 18, 1932 UNITED STATES PATENT OFFICE FREDERICK .B. WALTER, OF WABASH, INDIAIN A, ASSIGNOR TO 'B. WALTER 6t COMPANY, INC, OF WABASH, INDIANA, A CORPORATION OF INDIANA TABLE SLIDE summer Application filed Maya, 1929. Serial No. semis.

My invention relates to improvements in extension tables and particularly to the means for supporting the extension leaves thereof.

My invention relates particularly to that type of extension table wherein the leaves are adapted to be slid under the table when not in use and which when drawn from beneath the table are raised to a level to the table top.

It is one of the objects of my invention to provide a supporting means for those leaves which will permit them to slide in and out of position and which will support the same in such a manner that they may be readily raised or lowered for operating purposes.

For the purpose of disclosing my invention, I have illustrated one embodiment thereof in the accompanying drawings in which:

Fig. 1 is a bottom plan view of a table embodying my invention;

ing the leaves extended and lying in the same plane as the table top;

Fig. 3 is a sectional view showing the leaves depressed and lying beneath the table top and Fig. 4 is a detailed elevation of the leaf supported.

In the embodiment of the invention illustrated, I provide a suitable support or table base 1. The table top 3 is rigidly supported on this base in the usual manner. The table is provided with leaves 4 and 5, one at each end, which are mounted on suitable slides for permitting them to be moved from storage to extension position and vice versa.

To this end each leaf is provided with a pair of suitable slides 6 on which the leaf is mounted. These movable slides cooperate with relatively stationary slides 7 which are connected together by cross-bars 8 and 9. The opposite slides of each leaf are provided with racks 10 and 11 geared together by means of pinions 12 so that, the two leaves side of the table. The lip 14 is'bolted or angle lip 14 formed on the bottom thereof by which it may be secured to the table base.

Pivoted to this plate is a pair of levers 15 and 16, the pivots 17 of which are at oppo site edges of the plate. These "levers are p-ivotally connected together .as, at 18 and the lever15 is provided at its outer end with a U shaped clip 19 which is secured on the end of the lever by-apivot pin 20 and provided with a securing bolt21. A similar-clip 22 having .a 10011323 is connected to the opposite lever 16 by means of a link 24 pivoted at one end to the clip and at the other end to .an upwardly extending lug 25. Each of the levers .15 and ltihas an offset ear '26 preferably pivoted in position and this ear has extending therethrough .a bolt 27, the head of which is threaded into a coiled spring28, the opposite end of which is connected .to a stud129 extending from the side plat-e near 1 its upper edge. It is noted that eachspring Fig. 2 is a longitudinal sectional view showand its connection with the leverzextends at an angle thereto.

In assembly, a-support is arranged on each screwed to the base to position the plate 13 vertically. One of .the U-sliaped clips is connected to the end of one of the cross-bars 8 of the slide unit, the "-bolt of the clip being adapted to be passed through thecross-bars and the clip of the opposite lever is connect- .ed in :a similar manner to the end of the oppositecross-bars '9 of the slide unit. By this arrangement, the slide unit and the table leaves aresupported on the levers so that, the slide unit and leaves may be moved vertically. The strength of each spring is counter-balanced by .the weight ofv the leaves and the slide unit and due to the change of angular position of each of the leaves, when the leaves :are raised or lowered, the ratio of leverage exerted increases or decreases, de-' pending upon the position of the leaves, to compensate for the increase and decrease in tension of the spring so that the leaves will rmnain in whichever extreme position to which they may be moved. In operation the leaves are normally 'depressedland maintained in their storage position beneath the table.

When it is desired. to extend :the leaves they are pulled out and by a slight upward pressure are raised to a level with the table top, after which they may be moved toward the table top to interlock therewith. \Vhen it is desired to move the leaves to their storage position they are pulled out vfro-n1 their interlocking connection with the table top and by a slight pressure will be caused to drop to their lowered level and may be moved back to their storage position. connection 18 is loose enough to permit the two levers to swing about their respective pivots 17.

I claim asmy invention 1. The combination with a tablebase, of a table top mounted on said base, a table leaf, a slide unit support for said leaf to permit the same to slide in planes parallel with said top, a lever for supporting said slide unit pivoted on said base and having one end connected to said slide unit to permit said unit to move vertically, and a spring anchored at one end and connected at its other end to saidlever, the tension of said spring and the Weight of, the leaf and slide unit being so related as to sustain said leaf in either of the two extreme vertical positions to which it may be moved.

2. The combination witha tablebase, of atable top mounted on said base, a table leaf, a slide unit support for said leaf to permit said leafto slide in planes parallel' with said top, a lever for supporting said unit having one end pivoted on said base and 5 the opposite end connected to the slide'unit' and a spring angularly disposed relatively The pivotal of the two extreme vertical positions to which they may be adjusted.

5. An extension-table leaf-support comprising a main plate, two oppositely extending lever arms pivoted upon said main plate with their inner ends pivoted together, two clips, one carried by'the outer end of each of said levers, and a tension spring anchored at one end .upon the base plate and at the other end upon one of said levers.

In witness whereof, I, FREDERICK B. AL- TER, have hereunto set my hand at Vabash, Indiana, this 6th day of April, A. D. one

3. The combination with a table base, of

a tabletop mounted on said base, a table leaf, a. slide unit support for said table leaf to permit said leaf to slide in planes parallel to said top, a lever for supporting said slide L unit pivoted on said base and having one end connected to said unit, a spring having one end anchoredand the other end connected to said lever, the angular relation bemovement of said lever varies with the change in tension on the spring.

4. The combination with a table, base, of

L a table top mounted on said base, a pair of table leaves, aslide unit for supporting said leaves, a pair of oppositely extending levers for supporting said slide unit pivotally mounted on the base and having their ends pivotally connected, the opposite ends of said levers being connected to the slide unit,and a pair of springs havingon'e end anchored and their opposite ends respectively connected to said levers, the tension of said springs and the weight of said unitand leaves being so related as to sustain said leavesin either
