I ARTHUR BAINBRIDGE trading as Charles Topham & Co. of 11 Roscoe Street
Bunhill Fields in the City of London as Wire Weavers do hereby declare the nature
of this invention to be as follows:-
My Invention has for its object to provide a Tube Scraper and Brush combined
which is better suited to remove Fur Soot &c. from tubes than those at present
constructed.
According to my Invention and for this purpose I make a tube scraper which is
formed of two plates between which is fastened by suitable means a Disc of steel or
any other similar substance.
These plates and the Disc are arranged so that the cutting edges are set slightly
askew which facilitates removal of Fur Soot &c. from the tubes and prevents the
scraper from jambing against the sides of the tubes.
The Disc or cutter is made so that its cutting edges are on a bevel and the whole is
screwed on to the rod of the brush and if thought desirable a cutter may be placed at
each end of the brush that at the back end having a greater diameter than the front
scraper.
The plates are arranged so that one set can be used to scrape tubes of different
diameter which is attained by inserting larger or smaller Discs thus when the tubes
are very foul a Disc of a smaller diameter can be used first and after a Disc of larger
diameter can be inserted until the tubes are quite clean.
Dated this 12th day of November 1888.

page_text: I ARTHUR BAINBRIDGE trading as Ohas. Topham & Co. of 11 Roscoe Street
Bunhill Fields in the City of London as Wire Weavers 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 has for its object to provide a Tube Scraper and brush combined
which is better suited to remove Soot, Fur &c. from the tubes than those at present
constructed.
According to my Invention and for this purpose I make a tube scraper which is
formed of two plates between which I fasten by suitable means a disc of Steel or any
other similar substance.
These plates and the disc are arranged so that the cutting edges are set slightly
askew which facilitates the removal of fur, soot &c. from the tubes and also prevents
the scraper from jambing against the sides of the tubes.
The disc or cutter is made so that its cutting edges are on a bevel and the whole is
screwed on to the rod of the brush and if thought desirable a cutter may be placed at
each end of the brush that at the back end having a greater diameter than the front
scraper.
The plates are arranged so that one set can be used to scrape tubes of different
diameter which is attained by inserting discs of larger or smaller size thus when the
tubes are very foul a disc of less diameter can be used and afterwards discs of greater
diameter till the tubes operated on are quite clean.
Referring to the accompanying Drawings Fig. I represents a scraper of my
improved pattern as above described attached to a tube brush, from which the skew
setting can be seen Fig. II is made to represent the scraper end on.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :
1st. In Tube Scrapers the application of a. Disc fastened by suitable means
between two plates set askew to be used either in combination with a tube brush or
without.
2nd. The arrangement of the plates by which means Discs of various sizes may be
used all substantially as herein before described and set forth.
Dated this 18th day of December 1888.
