Improvements in Wire Twisted Brushes for Cleaning Bottles, Flues,
and for other Purposes.
I, ALBERT JULES THEODORE WILD of No. 5 Denman Street, London Bridge in
the County of Surrey (Engineer) do hereby declare the nature of this invention to
be as follows:-
Hitherto brushes of this class have been composed of two or more round wires
twisted together with Bristles between them.
I construct my present Brush of two half round "wires of the same size & length
with the bristles or Scratch Wires" (as used for Tube cleaning) between them, when
twisted up, the bristles are formed in the shape of an Archimedean screw and the
shank of the Brush is one solid piece of Iron round and smooth.
The Tuft is formed in a similar manner as described in my patent, No. 4326 dated
27 March 1886 of a fan-shaped appearance the bristles being inserted in a slotted tube,
which is screwed to the stem of the brush

accordance with my present improvements.
Figure 2 is an enlarged cross section of the (approximately) half round shaped wire
which 1 use.
Figure 3 is a view of the tuft separate and
Figure 4 is a view of a brush made in accordance with one part of my improvements
without any tuft.
The wire (or wires) a is formed approximately of a half round section and having
the edges rounded off as shown in Figure 2 to prevent injuring the bristles 6 laid in
between them the wires are then twisted up and the lower end of the two wires
secured in the form of a handle or in any suitable manner desired.
In order the better to tap the wire stein to screw the tuft (Figure 3) thereon I find
it very advantageous in making the brush to use only one wire bent over and the
bristles secured therein between the top part a' at the bend being tapped as shown in
Figure 1 to receive the screwed tube c¹ of the tuft c.

page_text: The tuft is formed of a slotted tube c¹ having a female screw therein at its lower
end to screw on to the male screw a¹ the bristles being secured in this tube in any
convenient manner.
The tube c¹ is slotted on one side only so that the bristles & spread out through the
slot as shown.
For some purposes the end tuft Figure 3 is not required and may therefore be
dispensed with the brush being formed as shown in Figure 4 without any tuft or any
screw for attaching same.
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. The use and application of wires of approximately half round (semi-circular)
cross section in the construction of wire twisted brushes substantially as and for the
purposes set forth.
2. The improved detachable tuft constructed with a tube slotted on one side only
and tapped to screw on and off the screwed stem of the brush substantially in the
manner and for the purposes herein before set forth.
3. The improved construction of wire twisted brushes either with or without a
detachable tuft substantially as herein before described and represented in the drawings
hereunto annexed.
