MOP WRINGER Filed Oct. 9, 1950 Patented Sept. 22, 1931 UNITED STATES GERRIT VAN DAAM. on iaaUrFA'rog;NEW, Yonx Mor WRINGER- Application filed VOctober 9, 1930. .SerialNm 487,387.

The invention relates to mop wringers. The purpose of the invention `is to provide means adapted to be attached to a bucket or other receptacle for wringing the water fromV the mop.

The invention comprises a cylindrical shell top 'of shell 7 and given a twisting motion having a corrugated wall in helical formation and a downwardly flaring member therein causing a compression of the mop as the same l0 is twisted into the shell.

Referring to the drawings, which illustrate merely by way of example a suitable embodiment of the invention Fig. 1 is a `plan view of the mop wringer attached to an ordinary bucket.

Fig. 2 is a vertical section on line'2, 2 of Fig. 1. t

Fig. 3 is a sectional detail on an enlarged scale.

Similar numerals refer to similar parts throughout the several views.

The invention comprises the cylindrical shell 7 t having a corrugated wall 8, the grooves or channels being in the form of a helix. This shell is shown as slightly tapering from the open top to the closed bottom although the taper is not believed to be essential. Within the shell 7 is positioned the tubular formation 9 having its axis correspending to that of the shell. This tubular formation 9 has a flaring development at the bottom, as at 10, with itslower edge or margin joining the bottom margin of the shell 7, as at 11, thus closing the shell at the bottom. This tubular formation 9 extends slightly above the top of the shell 7 and is closed at the top. This formationis provided with a number of holes 1 2 for the passage of water therethrough.

The shell is provided upon or near its upper margin with any suitable means, such as the hook 13, for engagement with the top rim 14, of a bucket 15 or other suitable receptacle. At the diametrically opposite side of the shell margin or rim from the hook 13, is provided another supporting means such as the bar k16 secured to the shell 7 at about the middle part thereof and having, at each end, means for engaging the opposite sides of the top rim 14 of the receptacle 15. Inv order that the device Amay be attachedv to different sizedv re.-

ceptacles,fthefbar 16 is tubular at each end 'and provided with hook elements 17 slidable therein, having the springs 18 forpullin'g the hooks tightly against the said rim 14. In operation the mop is inserted into the within the shell to causey it to follow the helical corrugations downwardly. This naturally crowds the mop into a gradually decreasing space, due primarily to the flaring shape of the central formation 9. This crowding is of course increased by providing a downwardly tapering shell. As the mop 1s crowded into smaller space it is of course i put under pressure to expel the water there# from, which waterpasses through the ports or holes 12 into the bucket or receptacle 15.

After thewater has been squeezed from the mop a reverse twist is given thereto and the mop is readily withdrawn from the shell 7.

What I claim is 1. A'mop wringer, comprising a hollow, substantially cylindrical formation having t its inner wall formedwith a helical channel, a body centrally positioned within the cylinder flaring toward the bottom so that the space between the central body and the surrounding cylindrical wall decreases from the top toward the bottom. L

2. A mop wringer, comprising a hollow, substantially cylindrical formation having its inner wall formed with a helical channel, a body centrally positioned within the cylinder flaring toward the bottom so that the space between the central body-and the surrounding cylindrical wall decreases from the top toward the bottom, said central body provided with suitably arranged ports for the escape of water.

3. A mop wringer comprising ay hollow, substantially cylindrical formation having its inner wall formed with a helical channel, a body centrally positioned within the cylinder flaring toward the bottom so that the space between the central body and the surrounding cylindrical wall decreases from the top toward the bottom, said central body provided with suitably arranged ports for the escape of Water and means for disengageably securing the device to a receptacle.
