DOUBLE-COMPARTMENT SINK INSERT Filed Dec. 9, 1954 "fT IFJENTOR. Em Lemma United States Patent Ofiice 2,784,418 Patented Mar. 12, 1957 2,784,418 DOUBLE-COMPARTMENT SINK INSERT Edwin Luoma, Detroit, Mich. Application December 9, 1954, Serial No. 474,124 1 Claim. (Cl. 4187) This invention relates to plumbing fixtures and particularly kitchen sink-s, and in particular, includes an insert or liner for converting a conventional kitchen sink into a double-compartment sink whereby one side of the sink may be used for washing dishes and the other side for rinsing the dishes and wherein either one or both of the compartments may or may not be used as may be desired.

The purpose of this invention is to provide an insert for kitchen sinks which converts a single-compartment sink into a double-compartment sink in which the insert is adapted to be placed in the sink and removed therefrom as desired.

Substantially all conventional kitchen sinks, particularly of the small residence and apartment types, are formed with a single compartment and, particularly in washing dishes, the entire compartment is partially filled with soapy water and it is substantially impossible to wash and rinse dishes at the same time. Furthermore, in numerous instances, kitchen sinks are used for shampooing hair and washing clothes and particularly clothes of infants and it is desired to place the washed pieces of garments and the like into a rinsing water as washing is completed.

With these thoughts in mind, this invention contemplates a lining of rubber or other plastic material having a transversely disposed intermediate divisional wall and in which drain plugs are provided at both sides of the wall wherein with the liner positioned in a kitchen sink two separate and independent compartments are provided.

The object of this invention is, therefore, to provide means for dividing a kitchen sink into two compartments in which the dividing means is adapted to be removed and replaced as desired.

Another object of the invention is to provide an insert or liner for dividing a single-compartment sink into a double-compartment sink in which the liner is formed of a relatively resilient material whereby breakage of dishes is reduced to a minimum.

A still further object of the invention is to provide a plastic liner for dividing a single-compartment kitchen sink into a double-compartment sink in which the liner is of a simple and economical construction.

With these and other objects and advantages in view, the invention embodies a liner or insert having a base the upper surface of which is inclined downwardly toward the center and the lower surface of which is provided with spaced longitudinally disposed ribs. The base is provided with upwardly extended side and end walls and a transversely disposed partition and drain openings are provided at low points therein.

Other features and advantages of the invention will appear from the following description, taken in connection with the drawing, wherein:

Figure 1 is a plan view showing a kitchen sink with the improved double-compartment insert therein.

Figure 2 is a longitudinal section through the insert taken on line 2-2 of Figure 1 showing the insert positioned in a kitchen sink, the sink being shown in broken lines and the parts being shown on an enlarged scale.

Figure 3 is a cross section through the insert taken on line 3-3 of Figure 2, also showing the insert positioned in a kitchen sink and the sink being shown in broken lines.

. chipping, cracking and breaking many Figure 4 is a perspective view illustrating the formation of the double-compartment kitchen sink insert.

Referring now to the drawing, wherein like reference characters denote corresponding parts, the improved double-compartment sink insert of this invention includes a base formed with sections 10 and 11 with end walls 12 and 13 extended upwardly from ends of the sections 10 and 11, a rear wall 14, a front wall 15, and a transversely disposed intermediate partition 16, the rear and front walls and partition also extending upwardly from the base, and spaced longitudinally disposed ribs 17, 18 and 19 on the section 10 and 20, 21 and 22 extended downward-1y from the section 11.

Section 10 is also provided with a boss 23 having a drain opening 24 therethrough and section 11 is provided with a similar boss 25 having a drain opening 26 therethrough.

The upper edges of the side and end walls of the insert are provided with a continuous flange, as indicated by the numeral 27 and, as illustrated in Figure 2, the flange 27 is positioned slightly below the upper edge of a sink, which is indicated by the broken lines 28.

With the size of kitchen sinks substantially universal or the same throughout the country, substantially a onesize liner is all that is required, however, it will be understood that the liners may be provided in diiferent sizes and may be formed of plastic, rubber or other suitable materials.

With the liner formed as shown and described, it may readily be inserted in a sink, used and readily removed therefrom. The conventional sink plugs are adapted to "be used in the openings 24 and 26 and the openings may be closed and opened as desired.

An insert of slightly resilient material would prevent dishes.

It will be understood that modifications, within the scope of the appended claim, may be made in the design and arrangement of the parts without departing from the spirit of the invention.

What is claimed is:

As a new article of manufacture, an insert for converting a single compartment sink into a double compartment sink, said insert being of unitary construction and being made of resilient material and comprising a base including a pair of sections sloping downwardly toward the center of the base, each of said sections being provided with a drainage opening, said drainage openings being arranged adjacent the inner end portions of the sections, a boss surrounding each of said drainage openings, a plurality of spaced parallel longitudinally disposed spacing ribs extended downwardly from the lower surfaces of said sections, said insert further including upstanding front, rear and end walls, a transversely disposed partition interposed between said end walls, and said partition being arranged at the junction of said pair of sections, the upper edges of said walls being provided with an outwardly extended continuous horizontally disposed fiange, said insert adapted to be placed in a sink and removed therefrom as desired.
