Patented Dec. 12, 1944 UNITED STATES PATENT oFFlcE 2,364,960 siNK STRAINER Maude Dunn, Birmingham, Ala. Application March 23, 1944, Serial No. 527,812
7 Claims. (Cl. '4-291) This invention relates to the class of strainers and pertains particularly to improvements in strainers such as are used'in the drain openings of sinks and the like. I I
A primary object of the present invention is to provide a sink drain strainer in which there is provided a vflexible mesh bag of suitable metal adapted to be supported in a frame structure within the drain opening, such bag being designed so that it may be partially turned inside out t effect the easy and quick removal of debris therefrom. v
Another object of the invention is to provide a sink strainer unit of the character stated in which the metal fabric bag is slidably coupled at its bottom with an adjustable securing 'element whereby the bag may be stretched out and held in such condition while the strainer is in use, the bottom securing means for the bag being readily releasable to permit the turning of the bag forl the emptying of the contents thereof.
Another object of the invention is to provide an improved sink strainer of thecharacter Stated wherein the metal mesh bag is detachably secured to a carrying frame, thereby permitting the ready removal and replacement of the bag when necessary.
Other objects and advantages of the invention will become apparent as the description of the same proceeds and the invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawing forming a part of this specification, is being understood, however, that the invention is not confined to a strict conformyity with the showing of the drawing but may be changed or modied so long as such changes or modifications are within the scope of the appended claims.
In the drawing:
Figure 1, is a View in top plan of the strainer unit embodying the present invention.
Figure 2, is a vertical section taken substantially on the line 2-2 of Figure 1.
Figure 3, is a 'partial section taken upon the line 3-3 of Figure 1.
Figure 4, is a partial section through the bottom part of the strainer taken on the dotted line 4-4 of Figure 1. l
Figure 5, is a horizontal section taken upon the line 5-5 of Figure 2.
Referring now more particularly to the drawing it Will be seen that the device of the present invention comprises a frame unit generally designated F which is designed to be introduced into the usual sump which forms the drain for a kitchen sink.
The frame F comprises a bottom plate I0 and a top ring or collar II connected together by a number of posts I2, here shown as being four in number. However, any number of such posts may be used and therefore theinvention is not to be understood'as being limitedto this prescribed or shown number;
The collar I I is defined by an encircling latererally extending flange I3 which, when the device is in working position, is flush with the bottom of the sink in which it is mounted.
Between the collar and the flange, the flange is provided with a plurality of apertures I4 for the purpose hereinafter stated.
The bottom plate Ill has a number of drain apertures I5 therein and at the center of this plate there is iixed a guide post I6 on which is slidably mounted the collar I1. The lower end of thise collar is integral with the annular flange I8 `which is provided with a plurality `of apertures I9 for the purpose hereinafter described.
Adjacent the bottom end of the post IB there is fitted in a suitable slot, not shown, in the post, the latch 20. This latch is of the type commonly found upon an umbrella shaft for maintaining the runner in place when the umbrella is opened or closed and it is spaced above the bottom plate I0 of the present device a distance only slightly greater than the length of the sleeve I'I'.
At its upper end the post I6 has the relatively large flat head 2| which prevents the slide I1 from escaping from the post.
Within the frame there is suspended a mesh strainer bag which is generally designated 22. This bag is formed of a suitable metal fabric and is preferably in a number of sections, designated 23, the longitudinal or side edges of which are suitably coupled or secured together by the links or clasps 24.
The bag is suitably tapered to fit the taper of the frame which, as shown, is of materially greater diameter at its top end than at its bottom, and the lower end edges of the sections 24 have attached thereto a means for coupling the sections with the runner flange IB. Such means is here shown as comprising sector plates 25, each of which carries a hook 26 which is engaged in an opening I9 of the runner flange, as is shown in Figure 4.
The top edges vof the sections 23 of the fabric bag are also provided with suitable means for attaching them to the collar II. Such means is here illustrated as comprising the arcuate metal strips 21, each of which carries a suitable number of hooks 23 for connection in the apertures I4 between the collar and the flange I3. Thus it will be seen that the bottom part of the bag is coupled with the runner or slide I1 While the top edges of the bag section are attached to the collar II and the sections 23 of thebag are of such length that when the runner I1 is secured beneath the latch 20 the bag will be drawn out fairly tightly Within the frame. v l
While the lower ends of the bag section have here been illustrated as attached to plate segments 25 and the top edges are shown as attached to arcuate strips 21, it is to be understood that the invention is not limited to this specific method of securing the bag to the frame. Also it4 is to be understood as being within the purview of the present invention to form the strainer bag as a single unit as Well as in sections. The for. mation of the bag in sections has the advantage that if one portion of the mesh becomes broken that particular section can be removed and replaced Wthout having to discard the entire bag. However, it will be readily apparent that the bag may be made as a single piece of material if desired. l
As previously stated, the present device, when in use, will be disposed in the sink drain opening so that as waste liquids are discharged into the sink they will flow over the ange I3 into and through the mesh strainer bag and solid matter carried by the liquid will be trapped in the bag. When it is desired to empty the strainer the latch 2B is depressed so as to release the slide collar I1 and the collar is run up on the post I6 so as to partially turn the bag inside out. The entire frame may be removed from the sink drain opening when the strainer bagis so turned so that the material therein can be thrown into a garbage receptacle or otherwise disposed of.
