Patented Jan. 5, 1932 JOHN A. KIMBALL, OF TAYLORVILLE, ILLINOIS ADJUSTABLE. PEDESTAL Application filed December 19,1930. Serial No. 503,587,;

This invention relates to supports especially adapted 'for supporting the tops of tables, and has for an object the provision of a pedestal whose height may be adjusted to regulate the height of the top of the table.

Another object of the invention is the provision of an adjustable pedestal which is simple in construction, easy to adjust, and will effectually hold a table top or other object in at a desired height.

lVith the above and other objects in view, the invention further includes the following novel features and details of construc tion, to be hereinafter more fully described,

as illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawings Figure 1 is an elevation illustratingt-he invention.

Figure 2 is a section on the line 2.2 of Figure 1.

Figure 3 is a view similar to Figure 2 showing the standard released.

7 Figure a is a section on the line 44 of Figure 2.

Figure 5 is a section on the line 55 of Figure 1.

Referring to the drawings in detail wherein like characters of reference denote correao sponding parts, the reference character'lO indicates a standard, to the upper end of which is attached a table top 11 or'other article to be supported. The standard is provided with circumferentially spaced lonas gitudinally disposed grooves 12 and these grooves are adapted to receive lugs13 and 14 which extend upward from the upper ends of downwardly and outwardly curved legs 15. The legs 15 are connected at their upper an ends by means of a strap 16, the opposite ends of this strap being secured to the legs 15 as shown at 17, while the intermediate portion of the strap is provided with an openingfor the passage of the shank 18 of the lug 14.

-13 The portion of the strap 16 adjacent the leg 15 is offset as shown at 19 for a purpose to be presently explained.

One ofthe grooves 12 is in communication with vertically spaced pockets 2O which'eX- tend inward from the bottom of the groove,

and these pockets are adapted to receive the lug 14am]. as the legs are connected at their upper ends by the strap 16, and also are connected intermediate their ends by braces 21, the lug 1 1 will prevent vertical sliding move ment of the standard 10. y

In order to release this standard andilpere mit of vertical adjustment, the leg 15 as a pivotal connection 22 with the connecting means 21, and due to the shape of the legs and to the relative arrangement of the parts, the

weight of the top, of the table and the weight of the standard ill act to keep the lug 14: in engagement within one of the pockets 20.

To facilitate removal of the lug and adjustment of the standard, the leg has pivotally connected theretjoas shown at 23, an eccentric lever 24, the beveled end 25 of which is adapt- 'ed to bear against the offset portion 19 ofthe strap 16. By operating this lever, the lug '1 14; maybe withdrawn from its pocket 20 into theadjacent slot 12, so that the standard may be adjusted vertically upward or downward, the leg 15 remaining in the position shown by the dotted lines in Figure 1. When proper adjustment has beeneffected, the lever 24c'will be released and the weight of the table top and standard will cause the lug 14 to enter one of the pockets 20 to hold the table in position.

The invention is susceptible of various changes in its form, proportions and minor details of construction and the right is herein reserved to make such changes as properly fall within the scope of the appended claims. 3

Having described the invention what is claimed is 1. In an adjustable pedestal for tables, a standard having circumferentially spaced longitudinally disposed grooves therein and spaced pockets extending from one of the grooves, legs extending downwardly and outwardly, means connecting the upper ends of the legs, means connecting the legs intermediate their lengths, means extending from the 5 upper ends of certain of the legs within the slots to guide the standard for vertical slid ing movement, means to mount one of the legs for pivotal movement, means extending from i I one of the legs for detachable engagement din within the pockets to hold the standard against movement, and means to move the pivotally mounted leg to withdraw the pocket engaging means.

2. In an adjustable pedestal for tables, a standard having eircumferentially spaced longitudinally disposed grooves therein and spaced pockets extending from one of the grooves, legs extending downwardly and outwardly, means connecting the upper ends of the legs, means connecting the legs intermediate their lengths, means extending from the upper ends of certain of the legs within the slots to guide the standard for vertical sliding movement, means to mount one of the legs for pivotal movement, means extending from one of the legs for detachable engagement within the pockets to hold the standard against movement, and an eccentric lever pivotally mounted upon the pivotally mounted leg and engaging the leg connecting means to move said pivotally mounted leg and withdraw the pocket engaging means.

3. In an adjustable pedestal for tables, a standard having circumferentially spaced longitudinally disposed grooves therein and spaced pockets extending from one of the grooves, legs extending downwardly and outwardly, means connecting the upper ends of the legs, means connecting the legs intermediate their lengths, lugs extending from the up er ends of the legs into the grooves for s11 ing engagement with the standard, the I of one leg being relatively long and engageable within the pockets to hold the standard against sliding movement, and an eccentric mounted upon the referred to leg and engageable with the leg connecting means to move said leg pivotally and withdraw the long lug from the pockets.

In testimony whereof I affix my signature.

JOHN A. KIMBALL.
