Slop drains, commonly found in meat packing houses, large restaurants, and other industrial installàtions, are often required to be cleaned due to their clogging because of the quantity and size of the waste materials handled thereby. There is a need to equip such drains with wide mesh reticulated strainers and substantially lie flush with the floor in which the drain opening is located. Because of the volume of debris handled by the drain, such strainers are required to be frequently moved and emptied without utilizing special tools therefor.
The instant invention discloses a variety of shaped reticulated strainers adapted to be inserted into the drain opening and supported by the drain bearing floor. A handle is pivo~ably secured to the walls of the strainer so-that~ in one mode, the handle utilized for removal of the strainer may be rotated to a preferred storage position adjacent the side walls of the strainer9 leaving the strainer opening unob-structed. The handle may also be permitted to be pivotably 8l:1 secured to the strainer walls and9 through the use o~ slo~s, be permitted to retract downwardly ~owards the lowermQ~t point of the strainerD S~ch handles may be secured to the inside or outside sur~aces of the strainer utilizing rivets therefor.
The handle, whilst residing below the uppermost marginai edges of the strainer, is disposed below any point on the floor accommodating the strainer. The handle may then be pulled upwardly so as to be accessible above the surface of the floor. In this elevated position, the non-rotatable ~ersion of the handle may be rotated and is cou~led to a floor portion of the strainer so as to cause such floor por-tlon to be rotated as well. When the floor portion is un-coupled from the walls of the strainer, it may be pulled upwardly with the accumulated debris thereon so as to elevate such debris above the surface of the floor, effectively cleaning out the strainer from large accumulated particles of debris.
Thus according to the present invention, there is provided a drain strainer comprising a waste accumulating con-tainer, said container having a plurality of holes therethrough,said container having an opening, said opening in said container defining a plane, said opening for the introduction of waste material into said container, sùpporting means for supporting said container within a drain opening, a handle, said container having a base portion, means to slidably secure said handle to :~4(3~
an opening in said base portion, said means to slidably secure including means to limit the upward displacement o~ said han-dle from said base portion and means to limit the downward displacement of said handle towards said base portion, means to selectively releasably secure said ~ase portion into and out of the interior of the remaining portions of said container, said handle at the upper end thereof defining a grasping portion extending parallel to the said p~ane defining said opening in said container~ said base portion having an inverted cupshaped surface extending upwardl~ into said container, said base por-tion is disposed having circular marginal edges, a plurality of threads being disposed on said marginal edges, said container having a circular opening therein, said circular opening car-rying a plurality of female threads, said opening in said base 15 portion defining a width and a size thereof, said handle having at least one lateral surface thereof greater in size than the width of said opening in said base portion whereby rotating said handle causes the rotation of said base portion and the dis-engagement of said base portion from said remaining portions of 20 said container.
The structure and method of fabrication o~ the present invention is applicable to a strainer fabricated from a mesh-like material such as stainless steel. The strainer is permitted to have any de5irable waste retaining shape such 25 as a rectangular, circular9 or conical shape9 and is provided with a mounting device used to support the strainer within the drain openingO Such a mounting device includes outwardly extending fingers affixed to the strainer in the area of the open edges thereof~ The fingers engage the flo~r surroundin~
the drain opening or a recess in the floor adjacent the drain openingO An inverted U-shaped handle is affixed to the side walls of the strainer utilizing rivets therefor passing -through slots in the two side arms of the U-shaped handle.
The handle may be extended upwardly and downwardly along the , length of the slots formed therein and may rotate r pivot about the rivets so that the handle may store in a plane parallel to the floor if desired. The handle may he secured to the innermost or outel~ost surf~ces of the stra ner a~d :,. .
may have a pair of outwardly extending wings affixed at the intersection of the ends of the hand grasping portion and the side arms bearing the slQts. I'he wings may be utilized~ if provided, to support the strainer therebelow by resting on - I
the surface of the floor surrounding the drain or i~ provided~ ¦
on a strainer which utilizes protrusions to the strainer for supporting purposes, to add supporting strength to the hand grasping portion of the handle, reslsting downward forces which, when applied tQ the handle, tends to deform the strain-~ er out of its desired shape.
; Disposing the uppermost part of the handle ahove the level of the floor, causes such handle to represent a hazard to personnel traversing the floor and tends to expose such handle to accidentally applied forces, resulting in damage or breakage thereof. Another embodirnent of the present invention utilizes a handle secured to the base regions of the strainer, such that the uppermost end of the handle is disposed residing below the uppermost surface of the strainer when the handle is not being utilized. Grasping the wings of the handle, loosely positioned in a horizontal planeS
and applying an upward force thereto, permits the handle to be relocated above the surface of the floor. I~ this posi-tion, the handle may be conveniently employed to remove the strainer from the drain opening carrying the strainer.
Conventional strainers accumulate small waste particles as well as large waste particles. The largest of the waste particles can never pass through the openings in the strainer co~tainer~ Some of the smaller waste particles accumulate within the strainer even though they are capable of passing therethrough. Applying a substantial hydraulic force, usually by-way of a stream of water under pressure, to a strainer having large and small waste particles therein, results in the large waste particles interferring with khe effective cleaning of the strainer walls by a water stream directed on the interior surfaces thereof. Removal of the large particles, whilst maintaining the strainer in the drain hole, facilitates utilizing water or other devices to clean the strainer~ permitting the water to enter into the drain opening direckly. This eliminates handling of a dirty strainer, transporting same to an area to be cleaned whereby such cleaning area mus5 have independent drainage facilities.
The present invention ukilizes a bottom portion of the strainer, threadingly engaged to the remaining portions of the strainer~ and carrying the-handle slidably a~fixed to an opening. The handle in the raised or lowered position may be utilized to release the base portion of the strainer, by rotating both at the same time, causing the base of the strainer to be pulled upwardly through the interior of the strainer, taking along with it the supported lar~e waste particles~ The base of the strainer is then maintained opened during the cleaning operat~on whilst the strainer is ~etained in the drain hole. Means are provided whereby the handle assembly is keyed to ~he lower portions of the strain-` 15 er~ in anti-turn fashion, and prevented from falling in - unlimited fashion down to the base regions of the strainer.

Fingers 16 extend outwardly from the rim of the uppermost maJor opening of` the strainer 10 and support the strai~er on floor 14. Handle 1~ has a hand grasplng portion 20 and side arms 22 and 24. The side arms are pivotably secured on the inside surfaces of walls 26 and 2~ of' strainer 10 utilizing rivets 30 therefor. The rivets engage slots 32 located in side arms 22 and 24. Thus~ handle 1~ may move in -~a-the direction of arrows 34 and concurrently may pivot about rivets 30 so as to store within strainer 10 as desired.
Figure 2 illustrates the uppermos-t lateral surface of a portion o:E a flat floor 14a containing a circular drain opening 36 therein~ Fingers 16 support circular strainer lOa within opening 26. Handle lga is provided with a hand grasping portion 20a and is secured to the outermost surfaces 3~ of strainer lOa utilizing the handle mounting means shown in Figure 1, including rivets 30, slots 32, and side arms 22 and 24 therefor. Handle l~a may be pulled outwardly from floor 14a to remove strainer lOa from opening 36 or"
alternatively, handle l~a may be pulled outwardl~ and rotated so as to rest on floor 14a, if so desired.
Figure 3 illustrates a plortion of strainer 10 to which is secured rivet 300 Side arm 22 has slot 32 located therein, through which rivet 30 passes. Side arm 22 is free to be moved in the directions of arr ows 34 and to be ro-tated in the directions of arrows 40, utilizing rivet 30 as a pivot point for side arm 22. Surface 26 is of reticulated design and has supporting P~ingers 16 extending outwardly from edge 420 Figure 4 illustrates a cone-shaped strainer lOb to which is affixed handle l~b. Hand grasping portion 20b is secured to strainer lOb at surfaces 26b and 2~b utilizing rivets 30a therefor. Wings 44 are co-extensive with hand grasping por-tion 2()b. The undermost surfaces 46 of wings 44 may, if desired7 be utilized to support strainer lOb within an opening in a floor, not shown. In such a case~ rivets 30a cou:ld be _9_ engaged within holes in side arms 22a and 24a. Alte~natively~
side arms 22a and 24a may be adpated with slots 32~ and strainer lOb may be provided with outwardly extending fingers 16, as shown in Figure 1, and utilized to support the strainer lOb within an opening 12 in the floor 14. In such an event 9 lowermost surfaces 46 of wings 44 rest upon the floor sur-rounding the opening in which the strainer lOb is located and provide additional support for the hand grasping portion 20b, which is free to ro~ate and retract utilizing slot 32 there-for.
--The handle l~b~may be adapted to the rectangular shaped strainer 10 shown in Figures 1 and 3, or to the circular shaped strainer lOa shown in Figure 2.
Strainer lOb may be employed with handle 1~ b or, alternatively, with handle 1~ as shown in Figure 1. Strainer lOa, shown in Figure 2, may employ handle l~b, as shown in Figure 4. Strainer 10, as shown in Figure 1~ may~ if desiredt ernploy handle l~b as shown in Figure 4. In the event that handle l~b is employed with strainer lOa,l as shown in Figure 2, or strainer 10, as shown in Figure 1, surfaces 46 may engage the floor portion surrounding the opening in which the strainer is located. However~ handle l~b cannot be folded inwardly into the opening of the strainer due to the outwardly projecting wings 44 thereof. As in the case of strainer lOb, shown in Figure 4, fingers 16 sllown in Figures 1, 2, and 3 may be deleted when utilizing surfaces 46 to support the strainer 10 or lOa, shown in Figures 1 and 2, respectively.

Releasably securing means are provided by which threads 7~ and threads ~0 may be engaged or disengaged from one another by the manual rotation of portion 60. When such threads are disengaged ~rom one another~ base portion 4~ may reside within strainer lOc and may be carried on portion 62. Thus, base portion 4 may be moved upwardly, in the direction o~ arrow 56, when threads 7~ and ~0 are disengaged from one another and when portion 62 of handle 20b is disposed upwardly7 in the direction of arrow 56, so as to have portion 62 of the handle engage and carry thereon the innermost lowermost surface ~4 of portion
4~ other locking meansJ different in construction from threads 7g and ~0 may be employed such as cammed surfaces engaging cam receiving grooves or the like.
Figure 9 illustrates uppermost surfaces 6~ of base portion 4~ having rectangular opening 76 therein. Portion 60 of handle 20b, shown in Figure 5, is shown passing therethr~ugh. Side 70 o~ portion 60 is shown being wider than side ~6 OI opening 76.
Thus~ when portion 60 is rotated in the direction of arrows ~, base portion 4~ rotates therewith. At all times, opening 76 is sized 90 as to permit portion 60 to easily slide there--through. Surface 6~ may be provided with openings 90 if desired. Svch openings facilitate base portion 4~ acting as a strainer as well.
It should be noted that base portion ~g hauing circular marginal edges, is permitted to ride upwardly in strainer lOc in the opening therewithin. Base portion 4~ ~Eybe fitted to strainer lOb, shown in Figure 4, wherein such strainer is disposed having a truncated conical exterior surface. It -should also be noted that cavity 64, shown in Figures 5 and ~, is defined by lowermost sur~ace ~49 shown in Figure ~, 8~
of base portion 4~, wherein lowermost surface.~ is an inverted cupshaped surface. If desired, base portion 4 may be flat and disc shape as well.
One of the advantages is a strainer apparatus having a conveniently located flush type handle affixed thereto.
Another advantage is a strainer with a handle that may retract from below its uppermost extended position to a withdrawn inwardly stored position.
Still another advantage is a strainer having a handle which can rotate to a storage position adjacent the side walls of the strainer.
Yet another advantage is a reticulated strainer of .inexpensive construction suitable for u.se in large drain openings.
A further advantage is strainer s}~Lapes which accommodate rectangular or circular drain openings and which are adapted with rotatable and retractable handles.
Another advantage is a handle which may pivot away from the opening ~..the strainer facilitating the convenient emptying thereof of debris or waste material accumulated therein.
A stlll further advantage is to provide a strainer whose bottom may be opened selectively so as to facilitate the draining of large particles of waste after th.e drain has been cleared of small waste particles under hydraulic pressure.
Thus, there is disclosed in the above description and in the drawings, embodimentSof the invention which fully and effectively accomplish the objects thereof~ However, it will become apparent to those skilled in the art, how to make variations and modifications to the instant invention..
Therefore, this invention is to be limited, not by the specific disclosures herein7 but only the appending claims.
