' UNiTED STATESg M'IENr ottica DUNCAN KENNER, OF NEWORLEANS, LOUISIANA, BY COURT ORDER IVIRS. `IEIVIMA TUJAGUE'KENNER SOLE HEIR .AND LEGATEE 0F DUNCAN KENNER, .DECEASED Mor HEAD vApplication iled Julyvl, 1929. Serial No. 382,484.

This invention relates to mop heads or` swabs, and has particular reference to an improved mop head of the type which is made up of a plurality of lengths of twisted stranded material. Y

Mop heads or swabs of this type have been found tovbe open to certain objections, no-` tably, the f tendency of the strands to move over to one side ofthe wringer when the same is passed through the wringer. After a careful analysis of the reasonfor this, it has been ltraced to the fact that the strands of a mop are'twist'ed in the same direction and that in passing the strands through ythe wringer rollers, an untwisting action isset up which ,l tends to curve the strands in a direction opposite to the twisting. l

It is, therefore, the outstanding object of` the present invention to overcome thisabove recited objection by producing a mop head composed of a group' of lengths of stranded material, approximately one-half of'v which lengths have their strands twisted in an `opposite direction to the other half and in which the lengths are alternatelyarranged in the group so as to counteract the tendency of the strands to move laterally during the wringing operation.

As a still further object, the invention aims to provide a mop in which' the grouped lengths of stranded material, a portion of which is twisted in an opposite direction to the remainder, coact with each 'other to neutralize the untwisting tendency and therefore minimizethe fraying of the free ends. Y

` Other objects of. the invention residein the production of an improved mop which does not materially increase the cost of production, while greatly adding to the'efiiciency derived therefrom.

Vi ith the above recited and other objects in view, reference is had to the ,following descriptionand accompanying drawings, in

.I which there is exhibited one example or embodiment of the invention, while the claims taken approximately. on the line 2--2 of Figure l. Y f 1 Referring to thev drawings by characters of Y reference, the mop head or swab'is designated n generally by the reference character A and is madeup of aplurality or group of lengths of stranded material, certain of which lengths v B are twisted in one'direction and theremainder of which lengths() are twistedein the Y acts the tendency of the 'respective lengths to move laterally during the wringing operation Vand neutralizes the untwisting Vtendency by thecoaction of the oppositely twisted lengths with each other for the purpose of minimizing the fraying of the free ends. lDue to this construction, it will be found that in addition to accomplishing a more thorough wringing ofthe mop, the length of life'and usefulness of the same will be materially increased by the minimizing of the fraying action.

What is claimed is:

l. A mop head composed of a group of lengthsV of stranded material, approximately one-half the number of which have the i strands twisted in an opposite direction to Vand toward the other half of said number'.

2. Amop head composed of a group of lengths of stranded material, approximately one-half the number of which lengths have the strands thereof twisted in an opposite direction to the other half of said number and `in which the oppositely twisted lengths are alternately arranged in the group.

3. A mop head including a plurality Aof lengthsvof stranded material arranged in side by side relation, in which the twists of the strands of alternately arranged lengths are disposed in opposite directions. j
