SINK STRAINEB.

Application filed January 20, 1928. Serial No. 248,097.

I This invention relates to new andv novel improvements in strainers and similar utensils and has particular reference to a utensll of improved construction adapted to be used 5 as a sink strainer.

Sink strainers of known construction are ordinarily formed of a material which will rust, corrode or otherwise deteriorate there by causing an unsightly discoloration of the sink in which the same is used.

Objects of this invention are to prov de a sink strainer of simple, durable construction which may be manufactured at a relatively low cost and which may be used indefinitely Without causing discoloratlon of the sink.

Other objects are to provide a sink strainer composed of hard rubber or other like material and to provide corrugated side walls which will materially strengthen the structure' and which will permit the liquid to drain from the waste material deposited therein. I

' An additional object is to provide a sink strainer-of rigid material having new and improved cushion legs therefor whereby the same will be supported in spaced relation tothe bottom of the sink and to thereby provide a strainer which will not scratch, mar,

I stain or otherwise injure the sink.

The above objects are accomplished'and additional ends are attained by the novel construction, combination and arrangement of parts hereinafter described and illus- 3 trated in the accompan ing drawin in which I have shown a pre erred form 0 the invention, it being understood that the invention is capable of various adaptations and that changes and modifications ma be 40 made or resort had to substitutions w ich come within the scope of the appended claims. v

In the drawings like characters are used to designate like parts as the same may.

appear in anyof the several views and in which a Figure 1 is a perspective view of a strainer constructed in accordance with this invention,

' Figure 2 is atop plan view of same,

Figure 3 is, an enlarged cross sectional view taken as indicated by the lines 3-3 of Fi ure 2. roceeding now to a detailed descri tion 5 of the invention with reference to the rawings, the bottom wall 5 and the side wall 6 are composed of a single piece of hard rubber or similar material. The bottom Wall 5 is provided over its entire area with a multiplicity of openings 7 The side walls 6 are corrugated to provide the vertical grooves 8 on the interior face thereof and the corresponding grooves 9 on the outer face thereof. The construction. is such that when a quantity of fruit parings or other refuse is stacked against the side wall 6, it will be held away from the grooves 8 and permit liquid to drain downwardly and escape through the openings 7. -The bottom wall 5 is also provided with a plurality of circular openings 10 which are substantially larger than the openings 7 and which serve as a seat for the rubber legs 11. Each leg 11 is provided with an enlarged knob 11 which is adapted to seat in the bottom of the sink. The reference character 11 denotes a cylindrical neck which is adapted to fit in the bore 10 and the reference character 11 denotes -a head which is formed on the upwardly projecting end of the neck 11. The legs 11 are preferably formed of soft, elastic rubber and'aresecured to the bottom 5 by forcing the head 1 1 into one of the openings 10. 'As the head 11, is composed of soft rubber, it is easily displaceable and can be 'forced through the openings 10 and will expand to engage the upper face of the bottom 5, thereby detachably securing the legs 11 to the strainer.

It will be seen that the legs 11 may be easily removed, cleaned and replaced when desired. The strainer is preferably molded of one piece of hard rubber, but may be formed to any degree ofhardness desired or molded of any suitable material. The side wall 6 isprovided around the upper edge .thereof with a facing 12 ofsoft elastic rubber. As the entire structure is molded and vulcanized in a mold, a soft rubber com-- pound is placed in the mold to form the,

a soft rubber compound and positioned in the mold to secure the same to the bottom wall 5 by vulcanization.

In use, the strainer is positioned in a sink i in the ordinary manner. The soft-rubber legs 11 serve to protect the sink and as the main body of the strainer is composed of hard rubber, it will not deteriorate and cause any discoloration of the sink. When it is desired to empty material fr'om the strainer, it may be inverted and the edge 12 may be struck on a relatively hard surface without injuring the side walls 6.

It will thus be seen that I have provided a strainer of simple construction which may be manufactured at a low cost and which will be very efficient in use.

Having thus illustrated my invention and described the same in detail, what I claim as new and desire to secure by Letters Patent 1s:

1. In a sink strainer, a bottom wall and side walls composed of one piece of hard rubber, a multiplicity of openings in said bottom wall, said side walls being vertical- 1y corrugated and having an upper edge portion composed of soft rubber formed integrally therewith.

'2. In a sink strainer, a, bottom and side Walls composed of one piece of relatively stiff rubber composition, a multiplicity of openings in said bottom wall, said side walls terminating around the upper edge thereof with the soft; rubber portion formed integrally therewith.

3. In a sink strainer of the class described, a bottom wall and side walls formed of one piece of relatively stiff composition, the side walls provided around the upper edge there: of with a soft rubber portion formed integrally therewith.

4. In a sink strainer, in combination a bottom Wall and side walls composed of one piece of relatively stiff rubber composition, a multiplicity of openings in said bottom wall, said side walls being vertically corrugated and having an upper edge portion composed of soft rubber formedintegrally therewith, said bottom Walls provided with additional openings adjacent each corner thereof and legs composed of relatively soft rubber fitted in said openmg.

In testimony whereof I have hereunto set my hand;

FRANK WESBEOHER.
