the County of Kent, for the Invention of "IMPROVEMENTS IN THE CON-.
STRUCTION OF TUBE BRUSHES USED IN CLEANING THE TUBES OF MARINE,
LOCOMOTIVE, AND ALL KINDS OF MULTITUBULAR BOILERS."
Sealed the 9th July 1866, and dated the 15th January 1866.
PROVISIONAL SPECIFICATION left by the said Cornelius Moriarty at
the Office of the Commissioners of Patents, with his Petition, on the
15th January 1866.
I, CORNELIUS MORIARTY, of Nelson Street, Greenwich, in the County of
Kent, do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN THE CONSTRUCTION OF TUBE BRUSHES USED IN CLEANING THE TUBES OF MARINE,
LOCOMOTIVE, AND ALL KINDS OF MULTITUBULAR BOILERS," to be as follows:-
My Invention relates to improvements in the construction of tube brushes.
for which a Patent was granted to me in the year 1856, being that numbered
1534, and dated 30th June; these brushes have the wire, hair, whalebone,
or other suitable material constituting the brushing or scrubbing part of the

page_text: instrament placed in a compact mass in the form of a screw or helix, which
has sufficient pitch and space between the thread or threads of the screw to
admit of the brush being screwed in through the ferrule of the tube. By
placing the bristles, whalebone, or wire in a compact mass in the form above
mentioned great stiffness of the brush is presented, while at the same time the
wire brush may be made of the full size of the tube by disposing the thread
so as to screw through the ferrule, as before mentioned. The wire, bristles, or
whalebone of the brush are further disposed in greater quantities in the middle
of the length of the screw, so that it presents greater stiffness and stability in
the middle than at the ends. I make these brushes by combining the wire or
other brushing material, which is first cut to any length to suit the diameter
of the tube for which the brush is required, between two, four, six, or other
number of wires (or other forms of iron adapted to hold the brush material
and to form the body of the brush) placed at right angles thereto, and twist
such wires or other forms of metal forcibly together so as to form a spiral or
screw of the required pitch, in order that the wires or other forms of metal
constituting the body or frame of the brush shall hold the brushing material
firmly between them. I interpose between such body wires and the brushing
materials thicknesses of india-rubber or other soft elastic material, which
imparts a better hold and prevents the brushing wires or fibres becoming
disengaged, which they are apt to do when no such elastic material is
interposed.

use; exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "IMPROVE-
MENTS IN THE CONSTRUCTION OF TUBE BRUSHES USED IN CLEANING THE TUBES OF
MARINE, LOCOMOTIVE, AND ALL KINDS OF MULTITUBULAR BOILERS,"
upon the
condition (amongst others) that I, the said Cornelius Moriarty, my executors.
or administrators, by an instrument in writing under my, or their, or one of
their hands and seals, should particularly describe and ascertain the nature
of the said Invention, and in what manner the same was to be performed,
and cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said Cornelius Moriarty, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement, reference being had to the Sheet of Drawings hereunto annexed,
and to the letters and figures marked thereon (that is to say):
:―
My Invention relates to improvements in the construction of tube brushes
for which a Patent was granted to me in the year 1856, being that numbered.
1534, and dated June 30th, these brushes having the wire, hair, or whalebone,
or other suitable inaterial constituting the brushing or scrubbing part of the
instrument placed in a compact mass in the form of a screw or helix, which
has sufficient pitch and space between the thread or threads of the screw to
admit of the brush being screwed in through the ferrule of the tube. By
placing the bristles, whalebone, or wire in a compact mass in the form above
mentioned great stiffness is presented, while at the same time the wire brush
may be made of the full size of the tube by disposing the thread so as to screw
through the ferrule, as before mentioned. The wire, bristles, or whalebone of
the brush is further disposed in greater quantities in the middle of the length
of the screw, so that it presents greater stiffness and stability in the middle
than at the ends. I make these brushes by combining and securing the wire-
or other brushing material (which is first cut to any given length to suit the
diameter of tube for which the brush is required) between two, four, six, or
other number of wires (or other forms of iron adapted to hold the brush
material and to form the body of the brush) placed at right angles thereto,
and twist such wires or other forms of metal forcibly together, and so form a
spiral or screw of the required pitch, in order that the wires or other forms of

page_text: metal constituting the body or frame of the brush shall hold the brushing
material firmly. between them. I construct them as follows:-According to
my improvements I interpose between such body wires and the brushing
materials thicknesses of india-rubber or other soft elastic material, which
imparts a better hold and prevents the brushing wires or fibres-becoming
disengaged, which they are apt to do when no such elastic material is
DESCRIPTION OF DRAWINGS.
Figure 1 represents in side view a tube brush constructed according to my
Invention, and Figure 2 a cross section of the same, which 'in general
appearance and construction is very similar to the construction of brushes
represented and described in the Drawing of Specification of Patent before
referred to, a detailed description of which it is unnecessary to repeat here.
According to my present improvements, instead of holding the brush' wires
or other brushing material a, a, by the direct contact of the body wires b, b,
(or it may be other form of metal) as heretofore, I interpose thicknesses of
india-rubber c, c, between them, as best seen in the cross section, Figure 2.
The strip of elastic material is separately represented in the flat at Figure 3,
and in cross section at Figure 4. The interposition of the elastic material
maintains permanently an elastic compression of the brush wires or other
material a between the body wires b, whereby a more secure hold and binding
of the brush wires a is produced, by reason of which elasticity of binding and
hold obtained of the brush wires they are far less liable to be released and
become detached than when held in a rigid manner and by the contact of
rigid substances; for this reason the brushes are much more enduring and
are smoother in their working, as the interposed india-rubber imparts a resilience.
to the brush wires in addition to their own flexibility. The brushes are made.
precisely as described in the Specification herein-before referred to, the body
wires 6 being twisted upon the brush wires a, the permanent twist given to
the wire holding the small wires a firmly between them, the ends of wires b
being secured by a point d, and by a cap and eye e, by which the 'brush is.
operated in cleaning tubes as well understood. Instead of four wires b, b,
(two pairs) as shown in the Drawings, each pair may be represented by.a
single piece of metal as described in my former Specification.
Having described the nature of my Invention, and the manner of performing
the same, I declare that what I claim as my Invention to be protected by the
berein-before in part recited Letters Patent is, the interposition of pieces of

page_text: india-rubber or other elastic material between the body wires or other
equivalents 6 and the brush wires or other material a, as and for the purpose
herein-before described.
In witness whereof, I, the said Cornelius Moriarty, have hereunto set
my hand and seal, this Eleventh day of July, in the year of our
Lord One thousand eight hundred and sixty-six.
