HARRY I. KLAWANS, OF CHICAGO, ILLINOIS.

MOI MATERIAL.

Application filed April 13, 1922. Serial No. 552,251.

To all whom t may concern Be it known that I, HARRY I. KLAWANS, a citizen oi' the United lStates, residing at Chicago, in the county of Cook and State or' Illinois, have invented a new and useful Improvement in Mop Materials, of which the following is a specification.

My present invention relates to improvements in mops, and has special relation to wet mops employed for washing' and wiping up lioors and the like with water as contradistincuished from dust mops and the like which are employed for taking up dry dust and are usually impregnated with some dust catching substance of an oily nature. Wet

mops are employed in distributing over and rubbing the floor, or other surface to be cleaned, with water in which is usually dissolv-ed an emollient for loosening and dissolving the dirt. The mop is then rung out and again rubbed over the surface in order to soak up and absorb the cleaning materials and dirt which have been dissolved and loosened thereby. It will at once be perceived that mops must be of wear resisting materials so as to stand the hard service to which they are put, and should also be of as absorbent nature as possible so that they may hold a maximum quantity of the cleanling fluid. Mops have heretofore been made of twisted strands of coarse yarn, or cord, or a woven material made of coarse yarn, twine or cord.

In the manufacture of articles from fibers or iilaments of a vegetable or animal origin, such, for instance, as cotton or flax or wool, the fibers or filaments are first disposed in parallel relation by a combing or carding process. Suitable size loosely twisted bundles of the carded material, called slubs or roves, are then taken to the spinning machine and drawn out and spun into yarn for the purpose of giving it the necessary longitudinal strength and reducing it to the desired size for which it is intended. The yarn is then used for knitting or weaving. or two or more strands thereof are twisted together to form thread or twine or string.

It will be seen that the drawing out and spinning of the slubs or roves into yarn, while it adds longitudinal strength to the yarn, also compacts the fibers together and renders the mass much less absorbent, and when the yarn is woven into fabric or materiah usually cotton.

twisted into thread or twine or string it is further compacted and rendered still less absorbent. Slubs or roves have not heretofore been considered suitable mop material as they are so loosely twisted as to b-e readily pulled out and the severe service which they would receive when formed into mops would quickly destroy them although they are much more absorbent than the spun yarn or an other material made therefrom.

lily present invention consists of making a mop or strands rformed by twisting together a plurality otl` slubs or roves of fibrous material with a reinforcement which will give the necessary longitudinal strength and wearing quality, thereby securing a mop which will stand the service and will be oiq greatly increased absorbent qualities and which may be manufactured and sold at a moderate price. I have illustrated a. form of mop material embodying my invention in the accompanying drawings which I have found to have both excellent absorbent and wearing qualities, although it will be obvious that a reinforcement of more or less strands or yarns may be employed without departing from the principle of my in vention.

In the drawings:

Fig. l is a view of a mop embodying my invention, and

Fig. 2 is a view on an enlarged scale of a short length of material from which the mop is made.

Similar reference characters refer to similar elements in the'respective views.

In the making of my mop I take a suitable number of slubs or roves 8 of suitable In Fig. 2 of the drawings, I have illustrated six of these elements, which is a suitable number for mops for ordinary floor use, but it is olovious that a greater or less number may be taken according toy the sizeof the mop which is desired and the use to which it is to be put. W'ith the slubs or roves 3 I also take a string or twine l formed in the -usual manner by twisting together yarns 5. I have shown in Fig. 2 a string or twine consisting of four yarns. The slubs or roves 3 and the string or twine 4; are then twisted together in the usual manner, but so that the string or twine will lie substantially upon the surface and extend spirally of the slubs or roves. When longitudinal strain is put upon the combined slubs or roves and their reinforcement it causes the reinforcement to straighten and constrict the slubs or roves and absorb the strain which would otherwise pull them to pieces, but when the strain is relieved the parte reassume their normal condition. This dispo sition of the string or twine by gripping` the bundle tighter as strain is put on it holds the comparatively loose fibers of the slubs or roves from undue longitudinal extension and therefore from pulling out, while it does not, to any extent, compress or compact them and render them less absorbent. A sufficient number of elements formed as described to make a mop 6 of the desiredsize are taken and arranged in parallel relation, and I then stitch around and Vthrough them at their middle portions a tape.

4TWhen a mop made herein illustrated and described is subjected to severe service there will be at first some shredding); from the ends of the slubs or reves, but when it. has been worn so that from a quarter to half an inch of 'the ends of the twine extend beyond the ends of the slubs or reves it will be foundV that the mop is then much more wear resisting than the ordinary mops to be obtained on the market, besides being very much more absorbent.

l. A mop comprising a plurality of strands,y each strand consisting of a twisted bundle of reves of brous material with a cord of spun and twisted yarn disposed substantially upon the surface of and spirally of the roves.

2. A mop comprising` strands composed of roves of loosely twisted absorbent material, and a reinforcement composed of tightly spun and twisted yarn of more compacted and less absorbent qualities; the reinforcement being disposed substantially upon the surface of and spirally of the strands.

.A mop comprisingstrands each formed of loosely twisted extensible roves of fibrous material., and a comparatively non-exten' sible reinforcement disposed. spirally of said roves whereby longitudinal strain upon said structure will straighten out and constrict said reinforcement around said roves and relieve the latter of the strain.
