My present invention relates to improvements in mop wringers of the type involving a drainage passage-equipped wringer cup adapted to be mounted on a suitable mop pail or receptacle, and wherein a mop is inserted and placed under pressure to express excess liquid from the mop; the excess liquid flowing through the drainage passages in the cup and into the underlying pail or receptacle. More particularly, the present invention relates to an improved means for quickly and detachably attaching or anchoring such mop wringers to cooperating mop pails or the like.

A still further object of the present invention is the provision of an improved means for detachably anchoring the mop wringer of the class described to the upper edge portion of a cooperating pail or other receptacle Without boring any holes in, or otherwise defacing, the pail or other receptacle, and without the use of auxiliary clamping or anchoring devices, such as screws, bolts, or the like.

Still another important object of the invention is the provision of an improved anchoring device of the general character immediately above described which can be readily adapted to fit cooperating mop pails of different diameters.

A still further important object of the invention is the provision of an improved device for anchoring a mop wringer of the class described to the upper edge portion of a cooperating mop pail or receptacle, which is extremely simple; can be constructed at very low cost, and can be quickly and easily applied to the wringer cup on one hand and to the cooperating pail on the other hand.

A still further object of the invention is the provision of an improved anchoring device or means for mop wringers of the kind described which can be shipped together with a mop wringer in disassembled or knock-down form and be readily assembled and applied to the cooperating mop wringer by the ultimate purchaser.

The above and other highly important objects and advantages of the invention will be made apparent from the following specification, claims, and appended drawings.

In the accompanying drawings, like characters indicate like parts throughout the several views.

Referring to the drawings:

Fig. 1 is a perspective view illustrating a mop wringer of the class described detachably anchored to the top of a cooperating receptacle in the nature of a mop pail through the medium tion;

Fig. 2 is a greatly enlarged fragmentary sectional view taken approximately on the line 2--2 of Fig. 1;

Fig. 3 is an enlarged fragmentary detail view in side elevation looking from left toward th right in respect to Fig. 2;

Fig. 4 is a horizontal sectional view taken on the line 4-4 of Fig. 3;

Fig. 5 is a fragmentary sectional view in side elevation taken approximately on the line 5-5 of Fig. 4; and

Fig. 6 is a fragmentary view corresponding to Fig. 5, but showing a slightly modified form of wringer anchoring means.

The mop wringer herein illustrated for the purpose of example is of the kind disclosed and claimed in my co-pending application, Serial No. 699,100, now abandoned, filed of even date herewith. This mop wringer comprises a drainage passage-equipped cylindrical wringer cup I which is closely and finely perforated to provide the desired drainage passages and is provided at its top with an upwardly or outwardlyflaring mop-guiding skirt 2 and at its intermediate portion with an outwardly-pressed circular bead 3. In Fig. l, a mop is shown in approximately operative position within the wringer cup I. and this mop, which is of the commercial circular type, comprises a mop head 4 and a suitable handle 5. The receptacle on which the wringer cup I is mounted through anchoring means of the present invention is in the nature of a conventional mop pail indicated as an entirety by 6, said pail being provided with an outwardly-rolled rim 1 at its upper edge and being also provided with the usual bail pivotally secured thereto through the medium of anchoring arms 9.

With reference first to Figs. 1-5 inclusive, the wringer cup anchoring means comprises a pair of relatively long anchoring arms I0 and a relatively short anchoring arm II, said anchoring arms I0 and I I all being mounted on the wringer cup and projecting laterally therefrom and the said short arm II being approximately equally circumferentially-spaced between the opposite arms I0. Preferably, and as herein illustrated, the opposite anchoring arms II] are integrallyformed from a common bar or strip, indicated as an entirety by I2, and are connected by an intermediate segmental portion I3 of said bar I2 that closely embraces and matches the exterior contour of the cylindrical wringer cup I. The entire arm-forming bar I2 is rigidly, but detachably, anchored to the longitudinally-interbands I5 and I6, and which are passed through receiving apertures I5" and I6" in the bar I2 adjacent the inner ends of the opposite arms In.

The other end of the clamping band I5 is pro vided with a radially out-turned anchoring flange I1 in spaced parallel relation to the short anchoring arm II and screw-threaded clamping means in the nature of a nut-equipped clamping bolt or the like I8 is passed through aligned apertures in the flange I1 and short arm II to clamp the bands I5 and i6 tightly about the wringer cup. I. The'segmental clamping bands I5 and I6, together with the clamping bolt I8 1 and the intermediate portion I3 of bar I2 comprise a clamping band of the well-known split variety.

Adjacent their free ends,: the arms I8 and II are formed to provide centering shoulders Ill and II, respectively, and outwardly adjacent said centering shoulders the'lower edges of the arms I and II define upper pail'bead-engaging seat 21. outwardly of the said upper seats 21 the arms l0 and. are formed with anchoring hooks; the hook of arm II being. indicated by I9, the hook of one of the arms If! by 20, and the hook of theother arm Ii! by 2|. The hooks I9; 20, and'2I are turned backwardly and downwardly with respect to their respective 'arms, so that thefree' end portions thereof define lower pail beadseats 28 for engagement with the'lower surfaceof the pail head I. The lower seats 28 are located in ahorizontal plane'below theplane of the upper seats 21 andJareLIaterally' ofiset therefrom. The lower seats 28 of i hOOkS I9 and '29 are offset each in the direction of'the other hook I?) or ZII'andthe seat28 of hook 2I is offset in the to facilitate application of the device to a c-oopcrating pail or "the like.

The mop wringer may most conveniently be packaged for shipment with the anchoring device described in disassembled or knock-down form, but due to the simplicity of the construction described, the matter of assembling the parts may be readily accomplished'bythe ultimate purchaser, who needs only insert the hooks I. and'lfi 'through the apertures I5" and I6" respectively, insert the mop cup within the confines ofthe segmental clamping bands I5 and I5, and apply the nut-equipped clamping bolt I8. Withthis done, the matter of attaching the mophwringer to a conventional mop pail, such as herein indicated by 6, is easily and quickly accomplished in the following manner, to wit: The anchoring hooks I9 and are first hooked under the rim 1 of the pail. With this done, the free end portion of hook 2| will rest on the upper 7 sided the pail bead 20, assuming that the arms IIllare; of proper lengthforthe particular pail involved. Now,.to accomplish the anchoring of the mop wringer-to themop pail, itis merely necessary to 2 apply suflicient downward .pressure to the hook 2| through the medium of the handle 22 thereof to force the same around and under the rim I of the pail; this being accomplished by slight springing of the hook 2I, rim l, or a combination of both. In case it is found that the arms Ill are so longas to space the hook 2I outwardly of the rim 1, the arms In and II, which are initially straight, may be bent by hand to produce an effective shortening of the arms as measured on a straightline from their ends to their respective hooks. In fact, in the drawings, the initially straight arms I0 are shown as having been bent or warped to accomplish the desired foreshortening to fit the anchoring device of a mop wringer to the particular pail involved. It will, of course, be understood that the arms IE1 and II are formed of relatively soft or ductile metal, so that they may be rather easily bent by hand and will tend to remain in the bent position.

By reference to the drawings, it will'be seen that the bead 3 of the wringer cup I is seated against the upper edges of the clamping' bands I5 and It, so as to restrain the'mop cup against downward movement under pressure exerted on' the mop through the mophandle 5;

The modified form of the invention shownin Fig. 6 differs from the embodiment of the invention shown in Figs. l..5 inclusive only inthe manner in which the segmental clamping-bands I5 and I6 are secured to the bar-like element [2; and in Fig. 6, parts corresponding to parts in Figs. 1-5 inclusive are indicated by like characters. In Fig. 6, the bar I2 is provided adjacent the inner ends of its arm-forming portions. I0 with elongated slots 23and 24 which replace the circular apertures I5 and I6" of Figs. 1-5 inclusive, and the clamping bands I 5 and I6 are respectively provided with head-equippedaan- y choring tabs 25 and 26 that replace the.anchoring hooks of Figs. 1-5 inclusive- Theslots 23 and 24 are of justsuflicient length'and width to receive the heads of tabs 25-and 26' respectively, and'the said head-equipped tabs, being turned after insertion throughthe slots, become positively interlocked with the bar I2. This system of locking the elements together is particularly desirablewhen the metal employed is so light that the hooked tabs of the other figures might tend to straighten out and become disengaged under clamping pressure.

The segmental bands I5 and I6, together with the segmental portion I3 of bar I 2, jointly form what may be hereinafterreferred to alternately as a circular clamping band .or split circular clamping band.

What I claim is: V

1. A device for anchoring wringer cups to rimequipped mop pails, said devicecomprising an anchoring band adapted to receivea wringer. cup and having three circumferentiallyespaced. anchoring arms projecting therefrom, said arms being of relatively thin flat band stock disposed with their narrow edges one above the other, the outer portions of the under edges of said'arms providing upper pail bead seats, said arms being formed outwardly of said upperiseats with anchoring hooks, thefree end portions of the upper edges of which provide cooperatinglower pail beadseats disposed below the plane of the upper bead seats and laterally oifs'et from their respective cooperating upper bead .seats.

2. A device for anchoring wringer cups to rim-.

equipped mop pails, said device comprising an anchoring band adapted to receive a Wringer cup and having three circumferentially-spaced an choring arms projecting therefrom, said arms being of relatively thin fiat band stock disposed with their narrow edges one above the other, the outer portions of the under edges of said arms providing upper pail bead seats, said arms being fornied outwardly of said upper seats with anchoring hooks, the free end portions of the upper edges of which provide cooperating lower pail bead seats disposed below the plane of the upper bead seats and laterally offset from their respective cooperating upper bead seats, the lower bead seats of two adjacent arms, being later-ally offset from their respective cooperating bead seats each in the direction of the other said arm.
