UNITED STATES MOP Application led January T0 aZZ whom it may concer-n:

Be it known that I, CHARLns E. Knees, a citizen of the United States, and a resident of Chicago, Cook County, and State of Illinois, have invented certain new and useful Improvements in Mopv Heads, of which the following is declared to be a full, clear, and exact description.

This invention relates to mopheads or mop swabs (for use with Water for cleansing purposes as distinguished from oil mops, dry mops and chemically treated mops for dusting, or dish mops) and its principal object is to prolong the life and increase or enhance the efficiency of articles of this nature. The ordinary mophead is usually constructed of a plurality of separate lengths of so called mop yarn, made of strands of fibrous material twisted together, these separate lengths of so called mop yarn being grouped and, in accordance with one`form of mop, fastened midway between their ends with a strip of tape or the like; and, in accordance with another form of mop, is constructed by fastening, in various manners, to the end of a stick or handle, 'a grouped plurality of separate lengths of so called mop yarn made of strands of fibrous material twisted together. The great. objection to such mopheads is the inherent tendency of the strands, individually and collectively, of the twisted so called mop yarn, to untwist immediately and rapidly after put into use. The result is that when the individual strands' untwist, the mop yarn, which is composed of theseY individual strands, disintegrates rapidly and the fibres and batches of fibre fall away from the mophead or mop swab proper.v After a. mophead, made of strands, twisted together to form so called mop yarn, has been in use a short time, numerous particles or batches of fibers of the strands, individually and collectively, untwist, loosen and separate and are deposited on the floor. On account of the quick and constant falling away of these fibers the mophead itself soon wears away to such an extent that it is'inelficient for mop ing.-

I have effectively overcome these o jectionable features in mopheads by producing' a mophead or mop swab in-which the separate lengths of the fibrous material composing the mophead or mop swab, are formed of braided, woven, or otherwise interlaced strands of absorbent material, vwhereby the .v 11566-544' PATENT l l' CHARLES E. KREBS, OF CHICAGO, ILLINOIS.

HEAD.

2e, 1925. serial N0. 4,692. -v

tendency of the strands, individually andl i collectively, to untwist, loosen and separate from each other is reduced to a; minimum. lIn fact, when saturated with water, .the vlibers of the strands and the strands themselves, individually and collectively, of each separate length of the material, have a tendency to become impacted and are subject only to such disintegration andloss of fibers as is occasioned by the ordinary abrasion, friction andA wear and tear on the mop.A In order to obtain the most effective results with a mophead embodying the present invention, it is necessary that the strands-of the separate lengths of material be so braided, woven, or otherwise interlaced, or'

suitably arranged as to looseness orl tightness, that the separate lengths may readily, quickly and -copiously absorb water.

` With the above named objects and advan-.

tages in view this invention consists of a mophead formed of a grouped plurality of braided, woven, or otherwlse suitably interlaced separate lengths of fibrous or other i absorbent material. .It further consists of the other several novel features hereinafterv ment of one of the separate lengths of ,ab-

sorbent material of which the mophead is made; Fig.v 3 is a side elevation of a fragment of a slightly modified form df the separate length of absorbent material from which the mophead is constructed, and Fig. 4 is a perspective view of a fragment ofv another modified form of separate length absorbent material from which the mophead is constructed;

Referring to said drawing, a mo head illustrating a simple embodiment o this invention is seen at A, and in accordance with one style or form of mop, is made up of a plurality of separate lengths a, of absorbent material formed of braided or otherwise suitably interlaced fibrous strands, the separate lengths being grouped to form a swab-like structure secured together as for instance with a bindino' strip b, of tape or the like.' Usually the b1nding strip is sewed to and around the grouped separate lengths loo' terial, a,`are formed. of fibrous strands a1,

' mophead is which in accordance with one of the forms of the invention are braided or otherwise interlaced as seen in Fig. 2. Any desirable number of strands of fibrous material may be used in each separate length of material, but it is necessary to braid, Weave or otherwise interlace the separate lengths of material in a relatively loose manner in, order to rovide a structure that will be readily absorbent, pliable and easily handled when 1n use.

'In the form of the separate length fibrous material illustrated in Fig. 3, the strands of fibrous or other absorbent material a2 may be twisted together in accordance With the common practice to form ordinary mop yarn, and to prevent the twisted together strands of the separate lengths from rapidly untwisting, loosening and separating, I surround them with an open work or net like casing or cover formed of fibrous material a3, which. may be in the form ot a woven, braided, interlaced or otherwise formed tube of reticulated fibrous material. The reticulated easing may be made of relatively strong material such as string, twine or the like and the center section or core, may be made of strands of fibrous or other absorbent material. In this form of the invention also the strands of the center section or core, individually and collectively, are effectively prevented from rapidly untwisting, loosening and separating, as the fibers thereof are held together effectively by the braided, woven, interlaced or otherwise arranged, open work or net like easing or cover, with the result that the life of the greatly prolonged and the inherent objectionable feature of rapid disintegration of ordinary mops by untwisting, loosening and separating of the fibers 1s eliminated.

It will be understood that the separate lengths of absorbent material may be solid, or they may be hollow or tubular, Aas lllusl rapid which it is composed as illustrated in Fig. 2,

or they may be otherwise suitably secured.

to prevent rapid disintegration thereof..

More or less variation of the exact details of construction of the separate lengths of mop material is possible without deviating from the intent or object of this invention; I desire therefore, not to limit myself to the exact iorm of the construction shown and described, but intend in the following claims to point out all of the invention disclosed herein.

I claim new, and desire to ser-.ure by Letters Patent:

l. A mophead composed of' a grouped plurality of separate lengths of absorbent material, each separate length of material having interlaced strands at its exterior portion, arranged to prevent rapid disintegration of said separate length of absorbent material.

2. A mophead composed of a grouped plurality ot' separate lengths of fibrous material, each separate length of fibrous niaterial consisting of interlaced strands, arranged to prevent rapid disintegration' of said separate length ot mop material.

3. A mophead composed of a grouped plurality of separate lengths of absorbent material, each separate length of absorbent material having interlaced strands at its exterior portion and the strands at the extreme ends of each separate length of absorben-t material being further interlaced to prevent disintegration thereof.
