Improvements in Metallic or Wire Brushes.
I, KARL WINAND BEISSEL of 39 Hohenzollern Ring, Cologne on the Rhine in the
Empire of Germany, Engineer, do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
This invention relates to wire brushes, the wires of which are mostly assumed
to be of flat section. In order to give such wires a greater effectiveness when the
brushes are being used, the wires by this invention are twisted.
The invention will be described with reference to the accompanying drawings,
in which:-
Figure 1 is a view of the back of a brush made according to this invention,
Figure 2 is a sectional plan view of the back of a brush,
Figure 3 is a longitudinal section,
Figures 4 and 5 are end views,
Figures 6, 7, 8 and 9 are detail views of the wires of various sections
employed.
In Figure 6 a wire of flat section is shown such as has been hitherto employed
for ordinary wire brushes. Figure 9 shows such a wire having its two active ends
according to this invention twisted spirally. The working ends of such wires
may also be only a little twisted or merely turned to a right angle as shown in
Figure 8. Such wires may also be twisted as shown in Figure 7 in the form of a
ringlet. Wires twisted or curled in such a manner have all the advantages of the
simple straight wires, and in addition possess advantages over them in that their
working end sections do not stand parallel to the work to be operated upon but in
all directions, whereby, greater action is obtained. Instead of the working
ends standing close to one another as is the case in ordinary brushes with straight
wires, the twisted or curled ends of the brush wires may be held apart to a certain
extent, that is to say the working ends may be separated by certain distances.
The body of the wire brushes, that is to say that part in which the wires are
fixed, is also improved as compared with the brushes at present employed. It
is made of metal and in a peculiar manner which also forms part of the present
invention. For this object in order to form the body of the brush, two or more
metal surfaces are held a certain distance apart by means of insertions, or a sheet
of metal is bent round in such a way at an angle that two surfaces of the same
stand opposite or face one another at a certain interval. The wires are then
drawn through these facing surfaces. Figure 3 shows a longitudinal section of
such a brush. The wooden handle of the brush lies between the four times bent
round sheet of metal through which the wires pass. Screws e passed through the
sheet of metal hold the latter and the handle firm and also the metal back or
cover b which prevents the wires being drawn out. At the front end of the brush is
arranged a protective cap f, which has for its object when the brush is in use to
prevent the wires from being pushed or bent off and thereby broken directly at
the point where they emerge from the body of the brush. Such protective caps
may also be arranged at both ends of the brush.
The great advantage of the present metal brush body herein before described

page_text: over the ordinary ones made of wood consists in its simple and cheap manufacture
and also in the circumstance that the brush body being of metal is almost
indestructible and can always be re-filled with fresh wires, whilst the wooden
bodies of ordinary brushes are generally useless even before the wires are worn
away.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim is:
1. In metallic or wire brushes, the use of flat wires twisted or curled longitu-
dinally substantially as described.
2. The construction of a brush body of several metal surfaces held at certain
distances apart, and adapted to have the wires drawn through them substantially
as described.
3. In metallic or wire brushes, the use of protective caps in order to prevent the
wires breaking off in the brush bodies, substantially as described and illustrated.
