Improvements in and connected with Scratching or Scraping-
brushes for Cleansing and other Purposes.
I, THEODOR FINNE, of Wittenberge, in the Province of Brandenburg, Kingdom
of Prussia, German Empire, Engineer do hereby declare the nature of this inven-
tion, and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:―
This invention refers to scratching- or scraping-brushes, in which the block or
body proper is covered with a piece of stuff furnished with rows of parallel pieces
or pins of wire arranged vertically or nearly vertically to their base, or to the said
piece of stuff respectively; the latter is, generally, formed by so-called card-sheet,
the pieces of wire of which are bent angularly, like those of a carding-engine, and
I will in the present Specification use the term "card-sheet" for said cover of the
brush, although I do not confine myself to applying my invention only to brushes
with card-sheet proper. My invention resides in making the card-sheet
exchangeable, or, with other words, in constructing the brush in such a manner,
that said card-sheet may, if desired or necessary, be easily taken off, and replacing
by another one.
I attain said object by composing the body proper of the brush of two or more
parts, which are hinged, or otherwise novably connected, one to the other, and by
providing the card-sheet with apertures, by means of which it may be secured to
pins or hooks fixed to said movable parts of the brush. In order to take the
card-sheet off the brush, or to replace it by another card-sheet, the two or more
parts forming the body of the brush are placed at an angle to each other, so that
the card-sheet is freed from the tension which it was up to then exposed to; said
card-sheet may now be taken off the pins or hooks, and another card-sheet may be
put upon the same. The parts of the block are then brought back into their
former position, so as again to put the card-sheet under tension, and to cause it to
lie close to the surface of the block.
I have shown as an example one mode of construction of my improved scratching-
or scraping-brush in the accompanying drawing, in which the block or body proper
of the brush is composed of the two parts a², which are connected by
hinges b, and are each provided with a series of pins c. The latter take through
apertures a of the card-sheet d. The handle of the brush is divided in its
longitudinal direction in two parts el e², which are fixed one to one part of the
brush-block, the other to the other part of the same, and which may be connected
with each other by a hook f¹ and an ear f, or by other suitable means.
parts e e² are, thus, employed as levers for the purpose of obtaining a sufficient
tension of the card-sheet with the expense of but little power.
The
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. A scratching-, scraping- or cleansing-brush with a detachable or exchangeable
card-sheet or the like, having its block, or body proper composed of two or more
parts movably connected with each other, and having means allowing said card-
sheet to be taken off, or put on, by bringing the block parts into an angular
position, and to be fixed and stretched by bringing the block-parts into straight
position, for the purpose as described.

card-sheet or the like, having its block or body proper, as well as its handle,
composed of two parts movably connected with each other, and having means
allowing said card-sheet to be taken off, or put on, by bringing the block-parts
into an angular position, and to be fixed and stretched by bringing the block-parts
into straight position, for the purpose as described.
3. A scratching, scraping- or cleansing-brush with a detachable or exchangeable
card-sheet or the like, having its block or body proper composed of two or more
parts movably connected with each other, and having pins or hooks adapted to take
through corresponding apertures of said card-sheet, and arranged so as to allow the
latter to be taken off said pins or hooks, or put upon the same, by bringing the
block-parts into an angular position, and to be fixed and stretched by bringing
the block-parts into straight position, for the purpose as described.
4. A scratching-, scraping- or cleansing-brush with a detachable or exchangeable
card-sheet or the like, having its block or body proper, as well as its handle,
composed of two parts movably connected with each other, and having pins or
hooks adapted to take through corresponding apertures of said card-sheet, and
arranged so as to allow the latter to be taken off said pins or hooks by bringing
the block-parts into an angular position, and to be fixed and stretched by bringing
the block-parts into straight position by means of their handle-parts, substantially
as described.
5. A detachable or exchangeable card-sheet for a scratching-, scraping- or
cleansing-brush, having apertures adapted to take over pins or hooks of said brush,
substantially as described.
