in the County of Surrey, Engineer for an Invention of "IMPROVEMENTS IN
TUBE SCRAPERS OR CLEANERS
"
PROVISIONAL SPECIFICATION left by the said William Sydney Turner
at the Office of the Commissioners of Patents on the 26th January 1883.
WILLIAM SYDNEY TURNER of Camden Street, Walworth in the County of
Surrey Engineer "IMPROVEMENTS IN TUBE SCRAPERS OR CLEANERS
"
This Invention has for its object improvements in tube scrapers for cleaning
tubes in boilers, furnaces, and so forth.
In carrying out my Invention I adopt mainly the following arrangements:-
Two arms, bent in form, carry a scraper, preferably of a conical shape the front
of the said scraper being bent upwards or outwards to form the cutting edge for
scraping the tube.
Between the said arms, and preferably between the space occupied by the
scraper, a spring is secured to.said arms.
In applying my Invention to clean the tubes, the front ends are inserted into
the tubes, and the pressure causes the expanded parts to close up, allowing the
scraper to enter the tube, the spring pressing against same, so that on the scraper
being withdrawn, the spring presses against the same, causing the edges of the
scraper to press against the sides of the tube and clean same.
One great obstacle with existing scrapers is the difficulty of the scraper being
withdrawn should same be forced beyond the tube.
This is overcome in my Invention as the arms behind the scraper are so formed
as to allow same to be pressed together and the scraper to re-enter the tube.

by the said William Sydney Turner in the Great Seal Patent Office on the
26th July 1883.
WILLIAM SYDNEY TURNER, of Camden Street, Walworth, in the County of
Surrey Engineer, "IMPROVEMENTS IN TUBE SCRAPERS OR CLEANERS,"
This Invention has for its object improvements in tube scrapers, for cleaning
tubes in boilers, furnaces and so forth.
In carrying out my Invention I adopt the following arrangements.
Two arms bent in form, carry a scraper, preferably of a conical shape, the front
of the said scraper being bent upwards or outwards to form the cutting edge for
scraping the tube. Between the said arms and preferably between the space
occupied by the scraper a spring is secured to said arms.
In applying my Invention to clean the tubes, the front ends are inserted into the
tubes, and the pressure causes the expanded parts to close up, allowing the scraper
to enter the tube the spring pressing against same, so that on the scraper being
withdrawn the spring presses against same causing the edges of the scraper to press
against the tube and clean it.
One great obstacle with existing scrapers is the difficulty of the scraper being
withdrawn should same be forced beyond the tube. This is overcome in my
Invention as the arms behind the scraper are so formed as to allow them to be
pressed together and the scraper to reenter the tube.
Having this far described the nature of my Invention I will now proceed to
further and particularly describe same by reference to the accompanying drawings.
DESCRIPTION OF THE DRAWINGS
Figs 1 and 2 Elevations of improved scraper or cleaner.
A curved arms to which is secured spring B and scraper or cleaner C-D rod
screwed on at end of curved arms of scraper or cleaner, said rod being of suitable
length. My improved scraper or cleaner will not become choked as those at
present in use.
Having now particularly described and ascertained the nature of the said
Invention and in what manner the same is to be performed I hereby declare that
I claim the said Invention of Improvements in tube scrapers or cleaners
substantially as herein before described and illustrated by the accompanying
drawings.
In witness whereof I the said William Sydney Turner have hereunto set my
band and seal this twenty sixth day of July, in the year of our Lord one
thousand eight hundred and eighty three.
