Improvements in and connected with Brushes for Cleansing the Inside
of Tubes in Water Tube and other Steam Boilers.
I, JOHN RENTON, of 71, Hylton Street, in the Borough of Sunderland, Brass
Finisher, do hereby declare the nature of this invention to be as follows:-
My invention refers to a new or improved brush for cleansing the tubes of
boilers.
The brush can be adapted for cleansing the tubes of boilers of any size and
whether the tubes are either straight or curved or reduced in diameter in
different parts, and it is intended to be used with a pilot wire.
My invention consists of a steel brush which is circular in shape and the bristles
of which are made of round or flat steel wires
The brush consists of a number of short strands of steel wire of equal length,
the ends of which are bound round a hollow metal core of a concave shape in
such a manner that the wires forming the bristles protrude outwards from the
core which forms what may be called the base of the brush The tip ends of
the bristles are bent outwards still further. I then take a short length of steel
wire rope which has at one end a steel eye attached and pass the other end of
the rope through the hollow metal core in such a manner that such other end
Just protrudes through the core on the opposite side. I then fix a steel eye
to this end and solder the steel eye and the metal core forming the body of the
brush firmly together. The steel eve at one end is attached by a hook to a wire
rope by means of which it is pulled through the tubes of the boiler. The brush
1s so made according to the size of the particular boiler tubes for the cleansing
of which it is intended to be used that the ends of the flexible wires of which
the brush is composed (and which are bent outwards) being of greater circum-
ference than that of the inside of the tubes required to be cleansed will contract
as the brush is pulled through the tubes and pressing against the sides of the
tubes will act as a brush and thus cleanse the tubes.

Improvements in and connected with Brushes for Cleansing the Inside
of Tubes in Water Tube and other Steam Boilers.
I, JOHN RENTON, of No. 71. Hylton Street, in the Borough of Sunderland,
Brass Finisher, 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:-
My invention refers to a new or improved brush for cleansing the inside of

page_text: the tubes of boilers. This brush can be adapted for cleansing the tubes of
boilers of any size, and whether the tubes are either straight or curved or
reduced in diameter in different parts, and it is intended to be used either with a
small wie rope or an iron iod.
And in order that my invention may be thoroughly understood, I now proceed
to describe the accompanying diawings thereof, reference being had to letters
and figures marked thereon.
Fig. 1, is a section of the two exactly similar hollow metal cores a
concave
in shape with a washer b between which are the foundation of the brush.
Fig. 2, is an elevation of one of the metal conesc, with a perforated flange d
also used in building up the brush.
Fig. 3, is a plan of the top of Fig. 2

Fig. 4, shews the bolt e and nut f which binds the two cones to the two
cores a with a washer b between the two cores.
Fig. 5, shews, the steel wires g used to make the bristles of the brush and which
said wires may be either flat or round steel wire, ready to be bound with wire
lashing round the cores a
Fig. 6, is a view of the wires g bound round the cores a with wire lashing h,
and the wire lashing having been cut through on to the washer, and the two
cores thus separated and with the cones removed and with the ends of the
wire bristles bent outwards, and thus forming two brushes.
Fig. 7, is a view of a short section of wire rope
each end ready for actual use
:
with the brush k with eyes.at
When the making of the brush has reached the stage shewn in Fig. 6, a short
strand of thin steel wire rope 1 is then taken with a steel eye m at one end and
the other end of the strand is then passed through the brush end of the core until
A steel eve ml 18 then
such end protrudes through the other end of the core
The brush can
soldered on to this protruding end and to the body of the core
be drawn up and down the tube required to be cleansed by means of a wire rope n
with a hook o at the end which is hooked on to the steel eye m¹.
Fig. 8, 1s a view of the brush k fitted to the wire rod and having a handle p
with a loose fitting A with a part of the boiler tube in section.
Fig. 9, is a side view of Fig. 8, with the loose fitting A moved up near the
handle.
Fig. 10. 18 a plan of the underside of the fitting A.
Where the tube required to be cleansed is straight and has an entrance hole
which is smaller in diameter than the tube to be cleansed I use the fitting A
which is an additional improvement in the method of using the brush. The
fitting A when passed over the brush k contracts its diameter thereby allowing
the brush to be inserted in a hole smaller in diameter than the tube desired to
be cleansed as shewn in Fig. 8.
The tube can be then brushed To withdraw the brush press the fitting
marked A over the brush again.
When tubes of the description shewn in Fig. 9, are to be cleansed an end
piece marked be fitted which prevents the wires of the brush from coming up
against the fitting at the end of, the tube.and, being. thereby bent.
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 wha
I claim is
1. The brush for cleansing the inside of tubes substantially as above described
in this specification & illustrated in the accompanying drawings.
2. The combination and arrangement of the short strand of flexible wire rope
the brush and eyes, substantially as herein described and according to the accom
panying drawings.
3. In making a brush, the combination and arrangement of the core a washer

page_text: cones c perforated flange d bolt e and nut f, substantially as herein described
and according to the accompanying drawings.
4. The brush constructed with steel wires, substantially as herein described
and according to the accompanying drawings.
