and with a portion extending through a hole in the end piece 22, andcarrying a nut 27' The operator by loosenin the nut 27 can slide the end piece 22 slightly endwise by hand, thus virtually lengthening or shortening the supporting bar; and then by tightening the nut 27 he can clamp the end piece firmly in the position into which it is thus adjusted. B this arrangement the support ing bar can be readily and quickly fitted to pails of different sizes.

a U-bend 28, substantially like the U-bend l8 above described. The U-bend 28 carries a b screw 29 like the screw 19 above described, and which can be used in clamping the end piece 22 firmly upon the pail, the screw 19 extending beneath the bead 8, as shown at d the right of Figure 3.

By this arrangement the supporting bar as a whole canbe firmly clamped in position upon pails of different sizes, and in such man nor as to lie-entirely independent of any ears or their equivalent, used upon the pail for any purpose. w

A mop handle is shown at 30, and a mop head at 31, these parts constituting a form of mop generally employed in connection with a device of this kind. I

The manner of using the mop, by grasping the handle and thrusting the mop'head into the drain cup, and turning the handle in order to wring-or drain the mop head, is too well known in this art to require any further description.

As may be understood from the foregoing, the drain cup is permanently connected with the supporting bar; and the same drain cup may be used upon pails of difierent sizes.

The clamping of the ends of the supporting bar upon the pail is accomplished entirely by means of the screws 19 and 29 and U-bends 8 and 28. Since these parts anchor the ends of the supporting bar directly upon the upper portion of the pail, it is not necessary for the supporting bar or any part thereof to be lodged against any ears-of equivalent members with which the pail may perchance be provided.

' In order'to mount my device in position upon the pail, the supporting bar is first adjusted as to length, and thenthe U-bends are clamped firmly in position relative to the bead 8, all as above described; then the drain cup is forced down hard, so as to bring the bead 12 thereof down firmlf. upon the "drain cup and its supporting bar can be used with pails differing considerably in size.

I find that by forming and arranging the supporting bar and the swell 14: of the drain cupas above described, there is a considerable saving in the amount of metal required for the supportingbar, and some reduction in the weight thereof. This is due to the fact that The end piece 22 is further provided with the strains conferred by the drainage cup upon the supporting bar are edgewise of the ar, except as to the curved portion 15 thereof, and that this curved portion, which recelves the downthrust of the mop, is disposed edgewise relative to the strains thus prouced. 1 I find also that with the parts thus arranged, the' forcing of the drain cup down.

intoposition, so'that the bead 12 of the drain cup is-brought to rest directly uponthe adj acent portion of the bead 8 of the pail, does not cause the supporting bar to buckle or to pucker, or otherwise become distorted; the net result being that the drain cup is thus mounted very firmly in position.

I do not'limit myself to the precise mechanismshown as variations may be made without-departing from my invention, the scope of which is commensuratewith my claims.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is as follows 1. A mop wringer, adapted for use with a pail, comprising a drain cup located within said pail and provided with a swelled portion formed of deformable metal so as to fit the inner surface of said pail when pressed tight swelled portion formed of deformable metal adapted to fit to the contour of the inner surface of the pail when pressed tightly against said surface, and a supporting bar secured to said drain cup of a character to engage the pail and thereby hold the drain cup with the swelled portion thereof against the pail.
