MOP WRINGER WITH LEVER ATTACHMENTS Application filed November 23, 1929. Serial No. 409,200.

My invention relates to mop wringers of the type in which a drain cup is mounted within a pail, and used with a mop actuated by hand, for removing excess of water from 5 the mop.

My invention contemplates an improved lever attachment, suitable for use in connection with a mop and with a pail and drain cup, to facilitate forcing the mop head into the drain cup, and thus wringing the mop.

Reference is made to the accompanying drawings forming a part of this specification and in which like reference characters indicate like parts throughout all of the figures.

Figure 1 is a fragmentary vertical section through my device, and shows the lever attachment thereof in one of its normal positions. Y

Figure 2 is a fragireii'ary front elevation of the mechanism in Figure 1.

Figure 3 is a'section on the same line as Figure 1, but showing the lever attachment as occupying a normal position different from that indicated for it in Figure 1.

Figure 4 is a section on the line 4 4 of Figure 3 looking in the direction indicated by the arrows.

Figure 5 is a fragmentary plan of the mechanism shown in Figure 3.

A pail 6, made preferably of galvanized sheet steel, is provided with an annular bead 7 and detachably engaging this bead is a supporting bar 8, these parts being of the usual or any desired construction.

A drain cup is shown at 11, and is made of sheet material, preferably galvanized steel.

The drain cup is provided with drain holes 12, of suitable form to facilitate the discharge of excess water from the mop to be wrung.

The drain cup 11 is further provided with a bead 13 of annular form, this bead serving as a rim and being secured to or fitted upon the supporting bar 15 and tting upon the bead 19 of the pail.

A mop handle is shown at 14, and is of the type commonly designated as a mop stick. This mop handle carried a mop head 15, which in this instance is made up of strings, or rags.

Encircling the mop handle 14 is a collar 16, provided with a pair of ears 17. A bolt 18 extends through holes in the ears 17, and carries a nut.

The operator, by turning the nut and the bolt 18 relatively to each other, can tighten or loosen the collar 16.

A hook bar is shown at 19, and is provided with an end portion 20, bent and thus formed into a hook.

The hook bar 19 is provided with a flat portion 21, the latter being provided with a slot 22. The hook bar is further provided with a toe portion 23, having a pair of shoulders 24.

The hook bar 19 is preferably made in a single integral piece, by casting, pressing, or shearing; though this is not always essential.

The hook bar is so formed and arranged that it may occupy two distinct normal positions, indicated respectively in Figures 1 and 3.

The hook bar 19 can be brought into position substantially parallel with the handle 14, as indicated in Figures 1 and 2, and while in this position it rests' with its back against the mop handle. l/Vith the parts thus positioned, the mop may be used freely for scouring and washing floors or the like, without disturbing the hook bar, which is to all intents and purposes kept well out of the way.

As may be noted from Figure 2, the flat portion 21 of the hook bar is tapered slightly, or in other words is partially wedgeshaped, so as to rest upon the ears 17, with the hook bar in its idle position. This arrangement enables the hook bar to be supported in a state of stability, and prevents it from developing lost motion as the mop is swung around and used in practice.

It will be noted from Figure 3 that the slot 22 is slightly oblique relatively to the main body portion of the hook bar. This is to enable the hook bar, by its own weight, to rest at two points firmly against the mop handle 14, as indicated in Figures 1 and 2.

By means of t-he construction just described, neither the hook bar nor any of the parts immediately connected therewith can shake loose or rattle, under ordinary conditions of operation.

In order to use the hook bar 19 so as to develop leverage between the mop handle 11i and the drain cup 11, the hook bar 36 is first lifted slightly, so that'the bolt 18 eX- tends through the bottom end portion of the slot 22; and this done, the hook end 2O of the hook bar is swung outwardly and obliquely downward, and thus brought to grip beneath the bead 7 of the pail. Then the handle 14: is grasped by hand, and forced gradually to the right according to Figure 3, as indicated by broken and full lines in said figure. By this arrangement the mop head 15 is forced downwardly into the drain cup 11, in consequence of the leverage brought to bear upon it, thereby wringing the mop.

It should be understood, however, that my improved hook bar can be used in connection with practically any mop handle such as is ordinarily used in connection with the drain cup.

I do not limit myself to the precise mechanism shown, as variations may be made therein without departing from my invention, the scope of which is commensurate with my claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is as follows 1. The combination of a pail, a drain cup carried thereby and supported thereupon, a mop for fit-ting into said drain cup, and mechanism carried by said mop and provided with a hook mounted to swing relatively thereto for the purpose of engaging the rim of said pail, in order to enable the handle of the mop to be subjected to leverage and thus drain the mop.

2. The combination of a pail, a drain cup supported thereby, a mop provided with a head for fitting into said drain cup a'nd also provided with a handle, a collar encircling said handle, and a hook bar pivotally connected with said collar and carried thereby, said hook bar having a hook for gripping the rim of the pail.

3. A mop provided with a head and further provided with a handle, a collar encircling said handle and provided with ears, a bolt extending through said ears, and a hook bar provided with a portion having a slot through which said bolt extends, said hook bar being further provided with a hook for gripping the edge of a pail.

4. A mop provided with a handle, a collar carried by said handle, a bolt carried by said collar, a hook bar provided with a slot through which said bolt extends and further provided with a toe portion and with shoulders carried by said toe portion for engaging a portion of said collar and thereby limiting the movement of said hook bar relatively to said collar.

5. The combination of a mop provided with a handle, a collar encircling said handle and provided with ears, a hook bar pivotally mounted upon said collar and having a portion extending between said ears, said hook bar being provided with a toe portion and shoulders carried by said toe portions, for engaging said ears of said collar and thus limiting the travel of said hook bar relatively to said collar.

6. The combination of a mop provided with a handle, a collar mounted upon said handle and provided with ears spaced apart and disposed substantially parallel with each other, a bolt extending between said ears, and a hook bar provided with a hook for detachably engaging the rim of a pail and also provided with a substantiall wedge shaped portion having a slot through which said bolt extends loosely in order to enable said hook bar to move endwise relatively to said bolt, said hook bar being movable into such idle position that said wedge shaped portion engages and rests between said ears of said collar and prevents lost motion as between said hook bar and said handle.

7. The combination of a mop provided with a handle, a bolt, means for supporting said bolt upon said handle and for spacing said bolt from said handle, and a hook bar provided with an endportxion formed into a hook and furthei*Il with another end portion having a"`s'l`ot, the position of said slot being oblique relativel to the length of the hook bar, said hook bar being so mounted upon said handle that said bolt extends through said slot, so that when said hook bar is in its idle position it is supported by said bolt and rests at two pointsE against said handle, thus preventing the development of lost motion between said hook bar and said handle.

Signed at New York city, in the county of New York and State of New York, this 22d day of Nov., 1929.

SOLOMON SCHULMAN.
