COMPLETE SPECIFICATION.
A Process for the Manufacture of Brushes and Brooms of every
description.
We, JOACHIM HEINRICH THEODOR HINTZE and JOHANN THOMAS CARL
STECH of Margarethenstrasse 2, Lubeck, in the German Empire, Manufacturers,
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:
The object of this invention is a process for the manufacture of brushes and
brooms of every description which can be applied to the most varied raw materials
for the purpose of producing brushes and brooms of every variety.
The accompanying drawings illustrate the new process in its application to the
manufacture of a piassava broom but it is obvious that this invention is not limited
thereto as this method of manufacture may be applied without requiring any further
explanation to all kinds of brushes and brooms.
Heretofore piassava brooms were formed by seizing a loop of piassava fibres
inserting it through the foundation plate and securing it thereto by means of a wire
or thread.
Now according to my present invention the piassava fibres are inserted in holes
formed in the foundation plate and are firmly fixed therein in any suitable manner
such as by driving in a key or wedge so that the unreliable fastening by means of
a thread or wire shall be dispensed with and the fibres need only have half their
usual length.
The accompanying drawings illustrate the manner in which the invention is
carried out
Fig. 1 being a vertical section of the piassava broom during the process of
manufacture.
Fig. 2 shows a tuft of piassava fibres and
Fig. 3 a section on line A B of Fig. 1.
A number of holes are formed in the foundation plate a these holes however do
not extend right through this plate but stop about half way from the outer surface
of this plate.
A number of tufts c corresponding to that of the holes are inserted in the latter
the diameter of cach hole corresponding exactly to the thickness of each fibrous
tuft.
To facilitate the insertion of the tufts the latter are curved at their base over a
cord d this however is not indispensable and is merely given here as an indication
for more readily inserting the fibrous tufts in the holes of the foundation plate a and
has no influence whatsoever on the peculiar manner of fastening the fibres in the
said foundation plate.
After the fibrous tufts c have been placed in the foundation plate a a small peg
or nail is driven by a hammer through the centre of each fibrous tuft and thus brings
the said tufts into immediate contact with the edges or walls of the perforations
holding them tightly therein while by subsequently driving this peg or nail into the
foundation plate a this hold is rendered still more secure. The fibres are thus so
tightly fixed in the ground plate that the use of tar or other binding means is
rendered entirely superfluous and unnecessary.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
A process for the manufacture of brushes and brooms of all description

page_text: characterized by inserting the various tufts of fibres in holes formed in corre-
sponding numbers in the foundation plate and having a diameter corresponding
with the thickness of the said tufts and by subsequently securing the latter in the
said plate by driving a peg or nail through the same and into a foundation plate
substantially in the manner and for the purposes hereinbefore described and repre-
sented in the drawings hereunto annexed.
