This invention relates to new and useful improvements in mop wringers and mops used in conjunction therewith.

The objects of the invention are to provide a mop wringer which is of simple but. rugged construction and which engages the mop while the latter is held stationary in said wringer and .extracts. the water from said mop in an efficient manner.

Other objects of the invention are to provide a mop wringer having its front wall formed with a seat to receive a mop and hold it in a vertical position with the mop strings presented inwardly, there being movably mounted in said wringer a vertically disposed presser .plate movable under pressure against said mop to extract water from said mop strings.

Further objects of the invention are to provide a mop having a back and a handle connected thereto, the mop strings beingcarried by a plate which in substantially coextensive with said back and is detachably secured thereto so that it can be replaced when worn- Additional objects of the-invention are: to pro- ,25 vide a. mop wringer which is compact in con.-

struction,. can be easily attached: to. a pail and supported independently thereof, and which is adapted. to receive a mop of special construction.

and engage under pressure the entire mop string. no surface thereof to extract. .the water therefrom while said mop is held immovable. in said wringer.

Withthese and otherobj ects in view, .my'invention consists in certain novelfeatures of construction and arrangement of parts, hereinafter more .35 fully described andclaimed and. illustrated in the accompanying drawings, in which Figure 1 is a side ,elevational view of my mop wringer showing the pail indotted lines.

Figure 2 is a frontelevational view of the mop wringer.

Figure. 5 is a top plan view of my improved mop. Figure 6 is a verticalcross sectiontaken on line 66of Figure 5. t

Figure '7 is an enlarged horizontal cross section throughthe forward end. of the mop.

Briefly stated, the mop which is of special construction is adapted to fltin a seat formedlinthe front wall of the wringer with thegmop strings presented inwardly and engaged by a movable plate of said wringer to extract water from said strings.

Referring by numerals to the accompanying drawings, 10 indicates a body portion of the mop wringer and 11 a pail to which it is attached. The body portion consists of an elongated hollow member open at both upper and lower ends 12 and 14, respectively.

It is substantially rectangular in cross section having a rear wall 15, side walls 16, and a front wall 17.

The. lower portion 18 of front wall 17 is slotted vertically and centrally, as indicated at 19, to permit the handle 20 of. a mop 21 to. pass upwardly therethrough. The upper portion of said front wall 17 is cut away to form vertically disposed oppositely and inwardly presented flanges 22. These flanges are arranged in a vertical plane spaced outwardly from lower portion 18, as shown in Figure 1. They are of sufficient widths to receive and engage the side edges of the back 21a of said mop when the latter is placed in position in the wringer.

The forward end of the back 21a is formed. so pointed as indicated at 211) and terminates in an outwardly curved. rubber insert or bumper 23. The mop strings 24 are attached to a plate 25 which: bears against the underside of back 21a. and fits within the downwardly presented margis5 nal: flanges21c of said back. A. screw 26 passes through an aperture formed in one of the flanges 21c and engages the plate 25, thereby securing. the latter to the back 21a.

A socket member 20a is provided at its lower ends with flanges 201) which are secured to the, back 21a by rivets 27. Handle 20 engages said socket member and extendsoutwardly therefrom, preferably at an. angle from vertical. A screw 28 takes the place of one of the rivets 27 and. extends through back 21a andengages said plate 25, as shown in Figure 6, thereby providing further attaching means for securing the plate and mop strings in position.

The lower portion of the socket member 20a is of less width than the width of slot 19 so that the mop can be moved upwardly through said wringer. The mop is placed in position therein with the pointed end 21b presented downwardly. The lower portion 18 of the front wall 17 has its upper corners offset laterally so that they are located in the same vertical plane with the. flanges 22 and form a seat. for said pointed end 21?) of said mop, as shown in dotted lines in FigureB- When thus positioned the back 2la disposed tion and provides stiffening therefor.

vertically with the mop strings 24 presented inwardly. A bell crank 29 is disposed in body portion 10 and has its ends journaled in the side walls 16 near the rear wall 15 substantially in horizontal plane with said ofiset corner portions 18a.

Preferably a reinforcing member 30, channelshaped in cross section, encircles the body portion 10 and has its ends terminating adjacent to the offset corner portions 18a. This reinforcing member is secured to the respective walls of said body portion by rivets 31 and forms a bearing for the ends of bell crank 29.

The central or ofiset portion 29a of said bell crank is disposed within said body portion and has loosely mounted thereon aroller 32 which bears against a track 34 vertically disposed. in said body portion.

This track is fixed to a presser plate 35 which latter extends between the side walls 16 while the track plate is comparatively narrow. The upper end 35a of said presser plate extends slightly above the open upper end 12 of said body portion 10 and the lower end 351) extends a suitable distance below the lower end 14 of said body portion and is disposed within the pail 11.

A retainer 36 is secured at its upper end to the rear face of track 34 and extends downwardly in spaced relation therewith and overlies said roller 32. Thus said roller supports the track member 34 and presser plate 35 and is held at all times in operative engagement therewith.

One end of the bell crank 29 is provided with a handle 37 whereby presser plate 35 can be actuated manually toward the mop placed in said body portion. A coiled spring 38 cooperates with the other end of said bell crank and serves to move the latter in opposite direction and move said presser plate away from said mop. Preferably said presser plate is provided with a plurality of apertures 40 to facilitate the extraction of water from the mop strings when said presser plate is forced thereagainst.

The mop wringer can be supported in any sui able manner on the pail. Preferably the lower ends of said walls 16 are provided with vertically disposed slots 41 which are adapted to receive the upper end of a plate, thereby supporting said mop wringer in position thereon. In order to eliminate sharp edges from hearing against the peripheral wall of the pail, walls 16 are provided with suitable castings 42 having slots 44 which coincide with slots 41 and having laterally and outwardly projecting flanges 45 which increase the surface contact between the wall of the pail and the mop wringer.

The pail 11 is preferably provided with a foot or extension 11a extending radially and outwardly from the lower end of the pail and arranged below said mop wringer so that the weight of the latter cannot up-turn said pail.

The upper end 12 of said body portion is preferably reinforced by a member 46 which is secured to the upper edge of the walls of said body por- A U- shaped handle 4'? is secured to said member 46 and to said walls 16 and provides convenient means for carrying said mop wringer.

Normally the mop wringer mechanism occupies positions shown in Figures 1 and 3 in which position the presser plate is retracted. When a mop is inserted into the mop wringer, as shown in dotted lines in Figure 3 and in cross section in Figure 5, handle 37 is operated to move the presser plate 35 forwardly against the mop strings 24.

The pressure thus applied against said strings causes the water to be squeezed therefrom. As the lower end 14 of said body portion and the lower end 35?) of said presser plate 35 are located within the pail 11 the water extracted from the mop strings drains into said pail. When the handle 37 is released, coil spring 38 causes the bell crank 29 to move into normal positf on (shown in Figs. 1 and 3) thereby moving the presser plate 35 away from the mop. Members 30 and 46 reinforce said body portion 10 and prevent any distortion thereof from undue pressure applied by the presser plate. The lower ends of aid walls 16 are preferably flared outwardly so as to facilitate the insertion of the mop within the body portion 10.

My improved mop wringer is of simple but rugged construction, can be easily moved and applied to any pail, and is highly efficient in performing its intended functions. The mop used in conjunction with my mop wringer has the mop string holder formed removable so that the latter can be readily depressed. The rubber tip with which may mop is provided prevents injury to the furniture or to the wall.
