BY W Mm Patented Sept. 20, 1949 l UNITED STATES PATENT,OFFICE DUAL-PURPOSE MOP HAVING STEEL AND FIBROUS PADS Walter S. Finnell, Elkhart, Ind.
Application June 17, 1944, Serial No. 540,833
This invention relates to a mop and has for its object the provision of a mop having a steel pad forming the bottom of the mop and another pad of resilient or fibrous material surrounding the steel pad.
Another object is to provide a mop of the character described which can be used for removing rubber burns and stains by abrasive action using the steel pad and then removing sand and dirt from the floor by means of the soft mop as hereinafter described.
Other objects and advantages will be apparent from the following description and the accompanying illustrations wherein a mop embodying the invention is shown.
In the accompanying drawings:
Figure 1 is a transverse sectional view, line |'-l of Figure 2, of a mop embodying the invention;
Figure 2 is a view partly in section on the line 2--2 of Figure 1; and
Figure 3 is a bottom view of the mop.
The mop has a bottom plate l which is substantially rectangular and of slightly curved section and which may be made of resilient material such as sheet steel. This has the upwardly and inwardly turned flanges ll, [2, and is provided with a central recess l3 and a hole I4 for the head and shank, respectively, of bolt IS.
A rectangular pad l6 of abrasive material is placed against the lower face of plate ID. This pad may be formed of steel wool as described in U. S. Patent No. 2.319 923, dated May 25. 1943, which teaches welding the strands of steel wool by suitable welds on the surface thereof, as indicated at I6 Fig. 3 hereof. These welds extend parallel to the longest dimension of the pad with the strands of steel wool running across the shortest dimension of the pad, the welds being staggered so that the bottom of the pad contains a number of protuberances which aid materially in the scouring action, each of said welds joinin a plurality of the strands of the pad.
An upper plate I! (substantially like l0) has a hole 20 for bolt l and is placed over the ends I1, I 8, of the pad IS, the plate I9 being so shaped as to permit its being forced downward to securely clamp the ends ll, l8 of the pad l6 between it and plate I0.
A pad, or mop, of comparatively soft fibrous 1Claim. (o1. 15-118)- 2 otherwise secured, together and apertured to receive bolt 15 and is now placed thereon to overlie plate 19. This pad is preferably of the usual mop type made up of strands of suitable ropelike construction which extend outwardly beyond pad [6, as shown in the drawings.
A Y-yoke having a transverse connection portion 22 stiffened at its center by plate 23 welded or otherwise secured thereto has a hole 24 through which bolt I5 extends, and washer 25 is placed on the bolt above the yoke and a clamp nut 26 is screwed down on the bolt, thereby securing mop center 2| and plates I9 and ID (with the ends I 1, l8, of the steel pad 15 therebetween) together.
The free ends 21 of the fibrous or soft mop freely extend outwardly all around the steel pad l6, and may be made of any desired length, and arelong enough to overlap and cover the lower surface of pad [6 if desired.
.The upwardly extending arms 28, 29 of the yoke are secured to the flattened portion 30 of the handle 3| in any suitable manner, as by bolt 32 and wing nut 33, whereby the yoke may be easily adjusted at any desired angle to the mop head.
In use, the unit mop above described may be applied to hardwood floor, or all types of waxed floors, to remove rubber burns and stains with out the use of oil solvents such as gasoline or naptha, the steel wool being brought into gentle contact with the floor, and as it has a large contact with the surface, considerable labor is saved over trying to remove such stains'by hand with steel wool.
Because of the resiliency of the steel plates holding the steel wool pad a smooth uniform pressure can be applied to the pad.
The polishin mop of fibrous material takes up the sand and dirt removed from the floor by the steel wool in the ordinary m'anner, acting as an ordinary dust mop in this respect. Obviously, the soft mop will not loosen sand and dirt and, particularly, will not remove dirt which has accumulated on a heavily waxed floor.
When it is not desired to use' the steel mop, the unit mop is brought toward the floor so that the free ends of the polishing or soft mop overlap or fold inwardly over the surface of the steel wool, which permits the mop to be used as an ordinary material has a center portion 2] stitched, or polishing mop if so desired.
What is claimed is:
In a mop, a rectangular pad of steel wool, the
strands of which lie across the shortestdimension of the pad, means for securing said strands together comprising a plurality of elongated welds spaced-apart and extending lengthwise of REFERENCES CITED The following references are of record in the file of this patent:
