Improvements in the Manufacture of Brushes.
I, JOHN BOSSE, of Kalkbranderinej No. 13, Copenhagen, in the Kingdom of
Denmark, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
•
This invention relates to brush making and has for its purpose to provide a more
useful means for binding the bunches of bristles or other material. Various means,
for instance hemp twine or metal wire, are used for the said purpose. For those
brushes, the material of which must be tied or bound in a moist state to avoid
breaking, or which in their use are exposed to moisture, twine is used, which is
naturally but little durable, while, when employing for such brushes metal wire,
the latter must either be of copper or brass or covered with material for obviating
rusting.
For securing brittle brush material in wood, naturally only soft material can be
advantageously employed, hemp twine having hitherto been commonly used for this
purpose.
In order to render the binding of brushes more durable on the one hand and
prevent injury to the material or oxidation on the other hand, I propose to use metal
wire coiled or covered with a soft, yielding material, for instance, copper wire in
connection with hemp, flax, jute, wool or other textile fibre.

Improvements in the Manufacture of Brushes.
1, JOHN BOSSE of Kalkbranderinej No. 13, Copenhagen Ô in the Kingdom of
Denmark, Manufacturer, do hereby declare the nature of this invention in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement :-
The object of this invention is an improved means for binding brushes and brooms,
more particularly such of soft and brittle material, for instance Piasava, whereby the
brushes or brooms are rendered more durable than those bound after the methods
hitherto known.
Various means are employed at the present time for binding brushes, for instance
twine from hemp or other material or metal wires.
For such brushes or brooms, the material of which must be tied in a more or less wet
condition in order to avoid breaking of the fibres, or such as are exposed to wet or
moisture in their use, twine is usually employed as a binding means, which however
ensures but little durability of the articles so bound. Where metal wires are used,
these must be either of copper or brass or coated with a substance preventing their
rusting.
For fastening however Piasava or other brittle material in wood blocks, only soft
material, for instance the commonly applied hemp twine can be advantageously
employed, as metal wires would cut and tear the brittle material.
..
To obviate the above drawbacks inherent to the means hitherto used for binding
the particular class of brushes or brooms mentioned, I propose to employ soft metal
wire entirely covered or spun with a soft and yielding substance, for instance copper
wire spun with hemp, flax, jute, wool or other suitable textile fibre.

page_text: It is obvious that the application of the improved binding means is not only
conducive to strong and reliable work and economy in raw material, but that the
brushes and brooms bound therewith will prove even more durable than those bound
with uncovered metal wire, as the coating or covering, beside sparing the brittle raw
material, also protects the wire entirely or partly from oxidation.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what 1
claim is:
In the manufacture of brushes or brooms, the application, for binding the bunches
of fibre and fastening the same in the block, of soft metal wire entirely covered or
spun over with textile or other yielding material, so as to form a substitute for
separately used metal wire or textile material, substantially as and for the purpose
set forth.
