COMPLETE SPECIFICATION.
A New or Improved Brush for Cleaning Bottles and other Hollow
Articles.
I, RUDOLPH JENTZEN of 62 Friedenstrasse, Altona-on-Elbe, in the Empire of
Germany, Manufacturer, 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 present invention relates to a brush for cleaning bottles and all other hollow
articles the interior of which is difficult of access.
In the accompanying drawings:-
Figure 1 is a longitudinal section through the brush; only some of the bristle-
tufts constituting the same being shown in place.
Figure 2 is an elevation of the brush.
Figure 3 is a detail view showing one of the bristle-tufts in section.
The brush consists of a stem A of copper, brass or any other metal which is
oxidisable with difficulty; to this stem there is adapted to be fixed, a' rod B of iron
which serves as the handle for the brush.
The stem A is pierced at its end and along its axis with a tapped hole C. Towards
the end of the stem A there are also pierced some holes D having their axes arranged
These holes also are
obliquely to the axis of the stem, as shewn in Figures 1 and 2.
tapped with screw threads. The stem A is also pierced over the whole of its length
with holes E whose axes are at right angles to the axis of the stem and are
arranged alternately, each one, or in twos (as shown in the annexed drawings), in
planes at right angles to one another. These holes have the same diameter and are
tapped with screw threads of the same pitch.
Into these tapped holes there are adapted to be screwed, the screw threaded
sockets F which form the mounts for small bristle-tufts G G composed of bristles, or

with these small bristle-tufts, it forms a complete brush whose elements are capable
of reaching into all the cavities and recesses of the bottles or other hollow articles to
be cleaned.
Each small brush is composed of a bundle or tuft of bristles or of stiff vegetable
fibres or of metallic filaments G, bent or folded together at its middle to enable it to
be then inserted as shown in Figure 3, into a copper or brass socket F to which the
tuft is firmly fixed by means of a circular beading H of the metal, the latter thus

screw threaded on its outer cylindrical surface. This screw threading corresponds
to that of the holes D and E of the stem. The hole C is intended to receive a tuft
of somewhat larger size and is therefore fitted with a socket of somewhat larger
diameter.
This construction and arrangement of the mounts of the tufts, and of the holes
formed in the stem for their reception allows of said tufts being removed and replaced

indefinite period of use.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is
(1.) A brush for cleaning bottles characterised by the removable arrangement of
the small bristle-tufts G which constitute the brush, said tufts being mounted in
sockets F (of brass or copper) screw threaded on their outer surface for the purpose
of being screwed into holes suitably pierced in a stem A of brass or copper or any
other metal that is not easily oxidisable, forming the body of the brush.
(2.) A brush constructed substantially as hereinbefore described and shown in the
annexed drawings.
