ment of the longitudinally adjacent faces of the strands. At the same time thereis no such interference between laterally adjacent strands, each strand being as free to move, so far as the strands on either side are concerned, as in the ordinary flat Wire brush. Thus, a much v superior result obtained over that secured in round Wire brushes Which l am Well aware have been crimped, for in the latter the-direction of the crimping With relation to the movement of the brush is Wholly a matter of indifference and cannot be controlled. Such brushes accord: ingly tend to become tangled fromvthe first and from use very quickly become f matted thus defeating the use of the brush in its proper Way at all. A peculiar efficacy is accordingly seen to be attached tothe application of crimping to the strands of the fiat Wire brush which so far as I am aware have lever been appreciated nor realized heretoore.

Having thus described my invention in detail that which I particularly point out and distinctly claim is 1. As an article of manufacture, a brush comprising a back and a plurality of fiat strands inserted therein, said strands having their flattened faces transversely crimped substantially throughout their length and being disposed with such faces transverse of the roposed direction of movement of the brus 1 in use.

2. As an element in a brush, a tuft consisting of a number of ilat metal strands doubled over and assembled .With their flat faces in juxtaposition, such faces being transversely crimped substantially throughout the length of the strands.

3. As an article of manufacture, a brush comprising a back, and a plurality of tufts .inserted therein, each such tuft consisting of faces transversely crimped substantially throughout the length of the' strand.

Signed by me this 15th day of November,
