c. E. KREBS MOP SWAB Filed Sept. 13; 1929 Patented Apr. 26, 1932 UNITED stares PATENT OFFICE CHARLES E. KREBS, OF CHICAGO, ILLINOIS MOP SWAIB Applicationfiled September 13, 1929; Serial No. 392,358.
laid together in a twine-like or rope-like structure in a relatively loose manner to produce absorbency, a necessary quality in a mop swab used with water. This grouped plurality of such cut-end or open-end separate lengths are usually fastened approximately midway between their ends to a strip of tape or the like, this construction of swab being used with a separate holder or handle not an integral part thereof. Another form of swab is constructed by fastening in various manners, as an integral part thereof, a grouped plurality of such cut-end or open-end separate lengths to the end portion of a handle or stick. I
Obviously the natural tendency of these an cut-ends or open-ends is to untwist immediately when put into service and rapidly thereafter on account of-their' comparatively loose twine-like or rope-like structure, whichconstant disintegrating process causes fibres and batches of fibres to fall away and the swab as a whole to become uneven and stringy at the cut-ends or open-ends making it unsuitable for desirable service, and to rapidly wear out.
4.0 I have effectively overcome these obj ectionable features by producing a mop swab in which any desirable number of single strands of absorbent material are tied together or otherwise fastened together at their cut-ends 4 or open-ends to form separate lengths, or in which separate lengths of absorbent material of multiple strands are tied or otherwise fas- V tened at their cut-ends or open-ends, thereby preventing untwisting'at'their cut-ends or 59 open-ends when in use, without, however, preventing untwisting under their normal tendency when in service ofthat portion of the- I separate lengths between their cut-ends or open-ends and the point where they are fastened to the handle or stick. I substantially prolong the life of the mop swab by retarding the normal disintegrating process at the cut 1 ends or open-ends, and make it a more eflicient cleaning implement by substantially longer retaining its original structure ofevennessat 60 the cut-ends or open ends. V
The present invention consists, therefore, in a mop swab formed of a grouped plurality of separate lengths of absorbent material with cut-ends or open-ends in which each separate length may be a single strand or any desirable number of strands twisted or laid together in a relatively loose twine-like or rope-like structure to produce absorbency,
and when single strand separate lengths are used, any desirable number of strands are tied or otherwise fastened together at their cut-ends or open ends to prevent untwisting. hen multiple strand separate lengths are a used, they are tied or otherwise fastened at their cut-ends or open ends to prevent untwisting or any desirable number of'multiple strands maybe tied or otherwise fastenedto gether at their cut-ends or open ends to pre vent untwisting. It further consists in a mop swab made of a grouped plurality of separate lengths of absorbent mop material stitched transversely'or lengthwise at their cut-ends or open-ends to prevent untwisting.
It further consists in the several novel features hereinafter fully set forth and claimed.
The invention is clearly illustrated in the drawings accompanying this specification in which- 1 Figure 1 is a-perspective view of amop swab embodying one form of the present in vention; i
Fig. 2 is a detailenlarged side elevation of a fragment of one of the lengths of material, from which the mop swab is formed;
Fig. 3 'is a detail cross section taken on the line -3'3 of Fig. 2; and J Fig. 4 is a detail fragmentary side eleva- 1 ment of 'the--mop swab tothe mop stick or pieces thereof on the floor and in the tion of a slightly modified form of the invention.
Referring to said drawings, a mop swab embodying a simple form of the present invention is seen at A in Fig. 1, and, in accordance with one form of swab, is composed of a plurality'of separate lengths 0; of absorbent material, usually formed of twisted together individual strands a of fibrous material having cut-ends or open-ends, said separate lengths ofmaterial being uncon nected except at the place arranged for attachment to a stick or handle. T he material from which the separate lengths as are made is commonly known as mop yarn.' The separate lengths are usually cut from mop yarn of indefinite-length to form separate definite lengths which comprise the mop swa=b.' The-ends of the separate definite -lengthspwhichendsare free, may be termed cut ends or. open ends. The separate lengths are grouped together to form a swablike structure and are usually secured together-at one'place only with a piece of bind- -ingrstrip:b of tape :or the like. Usually the binding strip is sewed to and around the groupedseparate lengths of absorbent material approximately midway between the ends'thereof, this being the place of attachhandleu. Any desirable number of strands of fibrous: material may be used in each separate-length of mop yarn, and it is possible to usemore than the ordinary number ofstrands-in each length, due to the fact that the ends are-fastened together which preventsnuntwisting of 'theend portions of the material but does' permit the untwisting of the'remainder ofthe; lengths.
Theestrands of each separate length of material are fastened together adjacent their cut or open end portions in any suitable manner; as, for instance, byrunning a row of stitches 0 along the'lengthof the materialzfor a short distance from the cut ends thereof; Thestitches fasten the individual strands together at;the cut end portions of the separate'lengths of material and effectively-prevent said end portions from untwisting under usage without, however, preventing the. remainder of the lengths of material from untwisting. dividual strands themselves are prevented from untwisting, and, consequently, the
fibrous material is kept intact,thereby not.
only prolonging the life of the mop swab and'increasing its efficiency, but effectively preventingrapid disintegration of the ma-' As a result, the in- By the term iseparate lengths in the specification and claims, is meant that the individual lengths which comprise the mop swab are not connected together in any manner except at the point of attachment with a handle and that their free ends are cut or I open.
More or less variation of the exact details of construction is possible without departing from the spirit of this invention. I desire, therefore, not to limit myself to the exact form of the construction shown and described, but'intend, in the following claims, to point out all of the invention disclosed herein.
I claim as new, and desire-to secure by Letters Patent:
1. A mop swab composed of a plurality of'relatively loose twisted separate lengths -of absorbent material grouped for attachment to a handle and having cut ends, each separately fastened at the cut end portion by stitches.
2. A mop swab composed of-a plurality of relatively loose twisted separate lengths of absorbent material grouped for attachment to a handle, and having cut ends, each separately fastened at the cut end portion by stitches running lengthwise ofthe material.
3. A mop swab composed of aplurality of relatively loose twisted separate lengths of absorbent material grouped for attachment to .a handle and having cut ends, each sepa-' rately fastened at the cut end portions by stitching running transversely of the ma terial.
