Description

Oct. 23, 1934. VE. M. MCNAMARA il! l ff W jaa/waff@ @ggf Patented Oct. 23, 1934 UNITED STATES PATENT OFFICE Rcliled for abandoned application Serial No. 610,344, May 10, 1932. This application April 30, 1934, Serial No. 723,221

2 Claims. (Cl. 15-229) e This invention relates to that type of mop cloths in which strands of loosely twisted cordage, wicking or the like are coiled upon a suitable form into a belt like structure to constitute the main- 5 body of the mop cloth with said strands constituting the longitudinal members of the mop cloth and secured together by transverse rows of stitching threads in spaced relation and constituting the tie members of the mop cloth, and this improvernent has for its object:

To provide a structural formation and combination of the longitudinal and tie members or strands of a mop cloth of the type above referred to, wherein the bunching together of the longitudinal strands in the form of lumps and like enlargements during continued actual use is avoided with a consequent lengthening of the life and efficiency of the article, all as will hereinafter more fully appear.

In the accompanying drawing:

Fig. 1 is a perspective view of an endless mop cloth embodying the preferred form of this invention.

Fig. 2 is a side view of the endless mop cloth.

Like reference numerals indicate like parts in both views.

As usual in the present type of endless mop cloths, the longitudinal members or strands 1 are formed of loosely twisted cordage, wicking of cotton or like fibrous material and wound in a close spiral upon a suitable form or frame, to constitute the main body of a mop cloth o'f the endless type, with such longitudinal strands so, formed, tied or secured together in proper rela,- tion by rows of tie stitchings 2 of threads at intervals along the length of the longitudinal members or strands 1.

The material feature of this improvement comprises the positioning of the tie members or stitchings 2 in oblique or diagonal directions in the longitudinal members or strands 1, and preferably in pairs of the stitchings having a diagonal and crossed relation one to the other as shown.

The scope of the invention however embraces any modified diagonal arrangement of the tie stitchings by which the novel function of the invention is attained and by which the formation of lumps and like irregularities in the mop cloth is avoided in the different operations of pushing the mop along the oor, pulling the same backward, as well as in passing the mop cloth through the wringer rolls or like mechanisms, in that such diagonal arrangement of the tie stitchings or strands 2 permits the longitudinal strands l to easily spread apart in a forward pass of the mop cloth upon the floor to be cleaned, and a correspending drawing together of the longitudinal strands 1 in a backward pull on said oor, with 70 a like ready alternating spreading apart and closing together of the strands 1 in the passage of the mop cloth through the wringer rolls or like fluid expressing means in the operation of forcing out of the mop cloth of the dirty fiuid taken up in the passage over the iioor being cleaned.

With this improvement uniform thickness of the mop cloth is maintained during continued actual use, with a corresponding extended and eifective life in the mop, with the resulting avoidance of decay and mildew due to varied degrees of dampness in a lumpy or irregular structure of the ordinary mop cloth heretofore on the market.

This application is a substitute for the previously abandoned application, No. 610,344, filed May 10, 1932.

Having thus fully described my invention what I claim as new, is:

1. A mop cloth of the endless band type formed by spiral windings of longitudinal strands and rows of tie stitchings of thread, with said tie stitchings having an oblique arrangement in relation to the length of the longitudinal strands.

2. In a mop cloth as specified in claim 1, and wherein the oblique tie stitchings are arranged in pairs having a crossed relation.
