' eb. 13, 1 34. s. SCHULMAN MOP Filed May 6' 1930 TEFR TOR 5270777077 277% Z 17mm m l/ 4%; ATTORNEY Patented Feb. 13, 1934 UNITED QFFIQ Claims.

My invention relates to mops of the kind used by hand and in connection with mop wringers, for general use in the household.

More particularly stated, my invention com- 5 prehends a mop of simple construction and having a number of desirable features, as hereinafter more particularly pointed out at length.

Reference is made to the accompanying drawing 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 side elevation of the form of my improved mop.

Figure 2 is a fragmentary end elevation of the same.

Figure 3 is a section on the line 3-3 of Figure 1, looking in the direction indicated by the arrows.

Figure 4 is a section on the line 44 of Figure 2, looking in the direction indicated by the arrows.

Figure 5 is partly a fragmentary side elevation and partly a section, of another form of my improved mop.

Figure 6 is a sectional view similar to Fig. 3 but showing the structure of Figure 5, and

Figure 7 is a fragmentary perspective showing how my improved mop is used with a mop wringer.

A mop stick appears at 8 and is provided with a metallic eye 9, serving the purpose of a ring, so as to enable the mop to be suspended from a nail or the like when not in use.

The mop stick 8 is provided with a threaded end portion 10, which is fitted into a threaded opening in a block 11, this block serving as a mop head.

The block 11 is provided with a pair of facets 12, which improve its form and avoid the use of sharp angles.

The block is further provided with a groove 13 extending lengthwise of the block, as may be understood from Figures 3 and 4.

The block also carries a clamping strip 14 consisting of a thin, flat bar of metal and extending lengthwise of the groove 13. The clamping strip is provided with end portions 15, bent upwardly as indicated in Figure 4, and with tips 16, integral with these end portions and bent slightly inward, as indicated in Figure 4. These end por- 50 tions and their tips are sunken into the block,

flush with its outer ends, and are held in position by nails 1'? and 18. The end portions and the tips are received within grooves which are formed in the opposite ends of the block to snugly receive them. By this arrangement the clamping strip 14 is effectively braced and greatly strengthened relatively to the block.

The mop threads are shown at 19, and for the most part extend crosswise of the mop head. A few of these threads, shown at are disposed adjacent the ends of the mop head, and extend therefrom in the directionof its length.

In assembling the parts I invert the block 11 so that the groove 13 thereof is uppermost. Next I lay the mop threads in position. Then I bring the clamping strip 14 against the mop threads and extend the end portions 15 with their tips 16 so as to fit into the ends of the block. Finally I apply the nails 17 and 18. Screws or other equivalent fastenings may be substituted for the nails. These nails or screws may be omitted, in instances where they are not required for purposes of strength.

As in some mops I use more threads than in others, I find it convenient to make the layer of mop threads of any desired thickness, and force the clamping strip 14 tightly against the layer before bending the tips 16, 16 inwardly, and then cutting the tips off at exactly the proper length. Thus I can provide the mop head with any desired quantity of threads 19, or in other words can make the layer of cordage as thick as required. 1

InFigures 5 and 6 I show a form of my invention differing slightly from the one just described.

In the form shown in Figures 5 and 6 I add a plate 21 made of flexible material, preferably soft rubber or rubber composition, between the block 11 and the clamping strip 14.

This rubber plate, because of its resiliency, cooperates with the clamping strip 14 in such manner as to grip the threads very firmly. The rubber plate tends to prevent scratching or otherwise injuring furniture as the mop is used in working around the same.

However, the chief use of the plate 21 is to enable the mop to be used for rubbing out grease spots, ink spots or the like, or for dislodging sticky or adhesive substances upon the fioor. For instance, a piece of chewing gum dropped upon the floor, and afterward spread out thin by persons stepping upon it may cling to the floor quite persistently. To remove, it the operator turns the mop handle down almost parallel with the floor, so as to reach the floor with one edge of the rubber plate 21, and then moves the mop back and forth so that the rubber plate acts somewhat after the manner of an eraser.

It will be noted that my mop, because of 'the improved form of the block 11, can be readily handled so as to reach spots otherwise not readily accessible, as for instance into corners and around the ends of thresholds. This enables the mop to be used to better advantage than usual.

As may be noted from Figure '7, my improved mop is well adapted for use with a mop wringer.

A pail is shown at 22, and a drain cup 23 is mounted upon the pail by means of a support 24.

By means of the mop stick 8 the mop threads 19 are lodged within the drain cup, and by turning the mop stick 8 the threads are twisted spirally around, as shown; and then, by simply pressing directly downward upon the mop stick 8, the water is forced out of the threads, and passes out of the drain cup down into the pail 22. The pail 22 is provided with a bail 25, of the usual or any desired construction.

As may be understood from Figure '7 the mop head, because of its form, has a considerable amount of surface in engagement with the threads, thus affording a good bearing for the mop stick and enabling pressure to be readily transmitted from the mop stick to the threads.

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. A mop comprising a i elongated block having a handle projecting therefrom at one side thereof, said block having a groove extending along one of its longitudinal edges and having other grooves formed in the end edges communicating with opposite ends of the first groove, a body of mop threads extending transversely across the first groove free of said second grooves, a clamp strip for holding said mop threads tightly within said first groove, said clamp strip being of U shape the connecting portion of the U extending along said first groove overlying said mop threads, the legs of the U extending upwardly along said second mentioned grooves away from and free of said mop threads and being of a size with respect to said second mentioned grooves so as to be snugly received within and against the walls of said second grooves, and a plurality of fastening pins extending through apertures of said legs into engagement with said block.

2.
