s claims.

This invention relates to an attachment for a conventional type of floor mop which attachvment is constructed for the purpose of wringing handle to an out-of-the-way position when not in use.

. Brieiiy described, the improved attachment comprises a sleeve slidably molmtedon the shaft or handle, said sleeve being provided at one end with an enlarged apertured cylinder into which the mop head is received when wringing the Water therefrom, said cylinder being provided at scription and drawings.

In the drawings:

Figure 1 is an elevation view showing the complete structure and illustrating the wringer pushed down to its operating or mop squeezing position.

Figure 2 is a view similar to Figure 1 observing it in a direction at approximate right angles to Figure 1.

Figures 3 and 4 are cross sections on the lines 3-3 and 4 4 respectively, of Figure 1.

Figure 5 is an enlarged longitudinal detail sectional view showing a latch forming a feature of the invention.

Figure 6 is a view which may be said to be on the line 6 6 of Figure 2.

Referring now to the drawings by distinguishing reference characters, it will be observed that the fabric mop proper is denoted by the letter A, this being attached to a back or head B which is in turn secured tothe handle or shaft C. The attachment and its appurtenances is denoted as a unit by the numeral 1. Broadly, this comprises a slide, and specifically the slide includes a sleeve 8 which fits rather snugly, but slidably on the shaft, said sleeve having a hand knob 9 adjacent its upper end for convenient grasping and utilization. The sleeve merges into a tapered enlarged portion I 0 at its lower end which is substantially frusto-conical and this joins to and is integral with an apertured shell or cylinder Il. This cylinder serves asa sort of receiver for the mop A when it is drawn up into thecylinder during the wringing or squeezing operation.

The wringer rolls or rollers are indicated by the numerals I these being preferably externally corrugated and disposed in spaced parallelism, and these rollers are mounted for rotation in opposed pairs of suitably designed carrier yokes or brackets I3. These brackets I3 are pivoted as at I4 on diametrically opposite sides of the lower end portion of the cylinder.

In a sense, the brackets or carriers I3 are in the nature of bell cranks with their adjacent ends pivoted together in overlapping form. The lower or outer end portions of the bell cranks are offset sufficiently to take care of the length of the wringer roll I2. The opposed pairs of brackets are held together through the instrumentality of coiled springs I4 which are connected therewith. It is evident, therefore, that when the rolls are on opposed sides of the mop A, as illustrated in the drawings, by drawing the mop upwardly therebetween the water is naturally squeezed therefrom. In order to permit the rollers to be spread apart to clear the head B while the attachment l is being pushed down for use or drawn up to an out-of-the-way position, I provide special means. The means comprises a pair of cords or cables I5. These are attached by connecting wires I6 which serve to join the respective pairs of brackets I3 together as illustrated for example, in Figures 2 and 3. 'I'he upper ends of the cables are attached to ears Il carried by a lever or latch I8. This is pivoted on the shaft I9mounted on an attaching collar 2o. The shaft is also provided with a pair of anti-friction rollers 2| over which the cable-ends pass as shown in Figures 4 and 5. This is merely to render the operation smooth and expeditious. It is evident that by catching hold of thelever IS and pushing it down from the upstanding position illustrated in`Figure 5, this exerts an endwise or upward pull on the cables. This action in turn, causes the carrier brackets for the wringer rolls to swing apart and in turn spreads the rollers. This is sufficient to enable the rollers to clear the head B either as the wringer l is pushed down for use, or lifted up to an out-of-the-way position when not in use. Normally, the wringer attachment l is up and out-of-the-way. When, however, it is desired to bring it into use, one hand is wrapped around the mop handle C and the other hand grasps the knob 9. By forcing the knob downwardly while still holding the handle C it is evident that the rollers I2 snap down Vover the head B and press rmly against opposite sides of the mop A through the instrumentality of the compression springs I4. By still holding the knob 9 Y and pulling upwardly on the handle C, the mop A is drawn between the spring-pressed rollers I2 and the water is squeezed therefrom. During its upward movement, the mop A recedes into the receiver or cylinder II. When it is desired to release the rollers I2, the latch IS is swung down to exert an upwardly pull on the cables and to spread the rollers apart in an obvious manner. Then the wringer 'I can be readjusted to its normal out-of-the-way position.

The purpose of the invention is obviously to provide a simple and expeditious wringer attachment :for a mop handle which can be placed on the handle and held in an out-of-the-way position under normal conditions without interfering with the use of the mop, and which may be put into position as shown in Figures 1 and 2 by the user for squeezing the water from the mop.

It is thought that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the invention after considering the description in connection with the drawings. Therefore, a more lengthy description is regarded as unnecessary.

Minor1changes in shape, size and rearrangement of details coming within the field of invention claimed may be resorted to in actual practice,

' if desired.

Y Havingv thus described the invention, what is claimed as new is:

1. In a structure of the class described in com- `bination, an elongated mop handle, a rnop swab secured to one end of said handle, a sleeve longitudinally slidable on said handle and adapted to receive said mop swab, a pair of brackets pivotally connected to the lower end of said sleeve, a pair of substantially parallel rollers carried by said bracket, said rollers being adapted to be positioned on each side of said mop swab, resilient means normally urging said rollers together, and 5 cable means secured to each of said brackets for pulling said rollers apart against the action rof said spring.

' 2. In a structure of the class described in combination, an elongated mop handle, a mop swab l secured to one end of said handle, a cylindricalshaped sleeve longitudinally slidable on said handle, and adapted to receive said mop swab, and being provided with a plurality of apertures therein, a pair of brackets pivotally connected to l the lower end of said sleeve, a pair of substantially parallel rollers carried by said brackets, said rollers being adapted to be positioned on each side of said mop swab, resilient means normally urging said rollers together, and a cable connected to each bracket, and means for moving said cable longitudinally of said handle for urging the rollers apart against the action of the spring.

3. In a structure of the class described in combination, an elongated mop handle, a mop swab secured to one end of said handle, a cylindricalshaped sleeve longitudinally slidable on said handle, and adapted to receive said mop swab, and being provided with a plurality of apertures therein, a pair of brackets pivotally connected to the lower end of said sleeve, a pair of substantially parallel rollers carried by said brackets, said rollers being adapted to be positioned on each side of said mop swab, resilient means normally urging said rollers together, and a cable connected to each bracket, and a pivoted lever on said sleeve, the upper ends of said cables being operatively connected with said lever for urging the rollers apart against the action of the spring.
