ADJUSTABLE LEG FOR SINKS AND THE LIKE Filed June 20 ATTORNEY.

Patented May 19, 1931 UNITED STATES WALTER J'. KOHLER, JR., OF KOHLER, WISCONSIN, ASSIGNOR TO KOHLER COMPANY, OF v PATENT? OFFICE KOHLER, WISCONSIN, A CORPORATION OF WISCONSIN ADJUSTABLE LEG FOR SINKS AND THE LIKE Application filed' June 20,

This invention has for its object to provide an adjustable leg for enameled plumbing ware having deep surrounding apron flanges such as sinks and particularly electric sinks, which, because of their weight, are desirably provided with legs in addition to their other support.

An object of the invention is to make the leg ofthe same material as the sink, that is enameled iron, and to provide it wlth an adjustment which will be located. behind the apron flange where it cannot be seen, thus permitting the leg to present a neat and ornamental appearance without undue enlargement incident to telescoping sections in a visible adjustment joint.

,Another object of the invention is to provide such an adjustable leg for sinks and the like with a spur point detachably mounted in its end to prevent the leg from slipplng.

Wit-h the above and other objects in view the invention consists in the adjustable leg for sinks and the like as herein claimed and all equivalents.

Referring to the accompanying drawings in which like characters of reference indicate similar parts in different views,

Fig. l is a front elevation of an electric sink provided with adjustable legs constructed in accordance with this invention;

Fig. 2 is an enlarged detail sectional view looking in the same direction as Fig. 1 showing one of the leg members sectioned at both ends;

Fig. 3 is a sectional view on the plane of line 33 of Fig. 1;

Fig. 4; is a bottom sectional view on the plane of line 44 of Fig. 2;

Fig. 5 is a top end view of the leg member, and

Fig. 6 is a bottom end View of the leg member. I

In these drawings, 10 indicates an enameled iron sink of the type known as an electric sink containing an electric dishwasher integral with the sink proper and provided with a deep apron flange 11 forming a roll rim around the front and ends of the device.

Adjustable leg members 12 are provided at each of the front corners or preferably 1927. Serial No. 200,145.

set back from the corner, as indicated in Fig. 3, and the adjustment feature of such legs is such that they present the same appearance whether adjusted to their minimum length or to their maximum length, the. former being shown in Fig. 2 and the latter in Fig. 3. The leg member is hollow and its upper end is preferably reduced for appearance sake, although this is not necessary, and is provided with internal screw threads 13, preferably in spaced relation to give the effect of an elongated bearing for a jackscrew member 14 threaded practically its entire length and fitting in the threads 13. The upper end of the screw member 14 is tapered and square in cross section, as shown in Fig. 5, to form a key head 15 and this fits within the tapering socket formed between a pair of ribs 16 cast on the bottom of the rim of the sink integral therewith.

At its lower end the leg member is internally screw threaded and a plug 17 is threaded therein, being provided with holes 18 to receive a spanner wrench for that purpose and in its center it has a projecting spur 19 to pierce the floor surface, whether it be wood or tile, and so prevent the leg from slipping.

In order to fit the leg in place it is only necessary to insert the key head 15 in the socket beneath the rim of the sink and then by turning the leg member so as to extend the jack-screw 14 while so confined in the socket, the leg member is elongated until the spur is driven into the floor surface and the leg attains the desired length to give proper support to the sink.

Whatever the adjustment of the leg members they will present the same neat and ornamental appearance for the adjustment parts-are entirely hidden from view by the apron flange of the sink and the leg members are rigidly held in place incapable of slipping at either end by reason of the socket and the spur provided for that purpose.

What I claim as new and desire to secure by Letters Patent is:

1. An adjustable support for sinks and the like comprising the sink or like member having a deep apron flange forming a roll rim,

and a leg member having a j ack-screw thread ed therein, said jack-screw engaging the under surface of the rim of the sink and thereby being prevented from turning and the up 5 per end of the leg member being hidden behind the apron flange in all the adjustments thereof.

2. An adjustable support for sinks and the like comprising an enameled iron sink or the like having a deep apron flange forming an enameled roll rim, and an enameled iron leg member having a jackscrew threaded therein, said jackscrew having a tapered square end forming a key, there being a correspondingly tapered socket beneath the roll rim of the sink formed between parallel ribs integral with the rim to receive the key end of the jackscrew and prevent it from turning, the upper end of the leg member being 90 hidden behind the apron flange in all of the adjustments thereof.

8. An adjustable support for sinks and the like comprising the sink or like member having a rim, and a leg member having a jackscrew threaded therein, said jack-screw engaging the under surface of the rim of the sink and means to prevent said jack-screw from turning.

4;. An adjustable support for sinks and the like comprising an enameled iron sink or the like having a rim and an enameled iron leg member having a jack-screw threaded therein, said jack-screw having a tapered square end forming a key, there being a s5 correspondingly tapered socket in the bottom of the rim of the sink formed between parallel ribs integral with the rim to receive the key end of the jack-screw and prevent it from turning.

5. A suitably supported sink or the like member having a roll rim with depending apron, a socket formed in the bottom of the rim, a leg member having a jack-screw threaded in its upper end with the end of the screw adapted to fit in the socket so as to be prevented from turning, said leg member being adapted to be so engaged in the socket after the sink is supported and then extended to engage the floor by turning it on the jack-screw, the end of the leg member and the jack-screw being concealed by the apron.

In testimony whereof, I afiix my signature.

WALTER J.'KOHLER, JR.
