DIECIFICATION,
I, WILLIAM HENRY GALES of 56 High Street, Poplar, in the Parish of Poplar
and County of Middlesex, Engineers Factor and Tube Brush Manufacturer, do
hereby declare the nature of my said invention for "AN IMPROVED TUBE
SCRAPER AND TUBE BRUSH COMBINED FOR THE REMOVAL OF SCALE OR
DEPOSIT AND CLEARING THE TUBES OF MARINE AND OTHER BOILERS," to be as
follows:-
This Invention has for its object further Improvements in Tube scrapers and
Tube brushes combined to that of the Provisional Specification deposited by me on
the 28th day of March 1884, and numbered 5094; which in the present instance
I propose to effect in the following manner, viz:
I take and form a scraper having a suitable cutting edge formed around it and
bent upward and of a suitable conical shape or form or nearly so and made by
preference in two parts or segments, rivetted or secured in position to a frame,
having an elongated curved guard or arms formed as part thereof and curved
inwards and outwards and so bent or shaped for the purpose of guiding or enabling
the scraper and Tube brush combined when in action entering the Tubes and per-
mitting of its easy return when passed through the same, and in a somewhat
similar manner and kind although of different form to the ordinary description of
scrapers which have been long known and in general use, which I propose by
preference to make of steel or other suitable metal but so arranged and proportioned
as to permit of sufficient elasticity being provided for the scraper to give or yield
when required in its passage on entering and passing through the Tubes when
opposed to any undue scale or corrosion, and yet capable to expand or give outwards
and clear all obstacles in its passage to and fro, and without the intervention of any
internal spring or springs; so that there is no tendency for the scraper to choke
or get out of order, and the refuse permitted to be afterward acted upon as hereafter
described.
In connection with the curved guard or arms as described and at the end of the
frame forming part thereof, I bend the same so that the end may have a screw
tapped therein, into which a spindle rod is capable of being screwed and firmly

page_text: secured with a washer and bolt or nuts so that the scraper with the frame and
elongated curved arms or guard to which it is fitted and firmly screwed up to and
attached to the rod or spindle.
Immediately behind the aforesaid Tube Scraper and elongated curved guard
arms and frame, I provide and fix in a suitable manner a series of curved or spiral
brushes arranged and securely fixed upon the spindle or rod of a suitable form and
material and of sufficient length and diameter according to the surface and extent
of the Tubes to be acted upon, and at the rear or extremity of the series of spiral
or coiled brush or brushes, which may be made either of steel, brass, Iron wire,
Bristles; Whalebone or other material, I provide a cup guard or washer suitably
formed and capable of being screwed up on to the thread of the rod or spindle bar
by means of a nut or nuts or other equivalent means so as to keep the brush or
brushes in position and yet capable of yielding and thus firmly securing the brush
and scraper together with the frame and curved guard or arms together upon the
Baid rod or bar, at the same time when wholly passed through the tube enabling
the same to be easily returned or brought back.
It will thus be seen that at one and the same operation in the process of cleansing
Boiler Tubes by my present Invention instead of by seperate operations of scraping
and brushing as heretofore, I am able to do so in a more rapid, effectual and perfect
manner as herein described, and in so doing prevent a material loss or reduction
of heat in the furnace and consequent gain of effective steam power during the
operation, and at the same time providing a very portable and useful Tube Scraper
and Brush in combination and not liable to choke or get out of order while
in use.
I provide a socket joint at the extremity of the rod or spindle bar for the hand
rod to be screwed or fixed thereto in the ordinary manner.

declare the nature of my invention for AN IMPROVED TUBE SCRAPER AND

to be performed, to be particularly described and ascertained in and by the
following statement and accompanying drawing:-
--
This invention has for its object further Improvements in Tube scrapers and
Tube Brushes combined to that of the Provisional Specification deposited by
me on the 28th day of March 1884 and numbered 5094; which in the present
instance I propose to effect in the following manner.
I take and form a scraper having a suitable cutting edge formed around it
and bent upward and of a suitable conical shape or form or nearly so and made
by preference in two parts or segments rivetted or secured in position to a
frame, having an elongated curved guard or arms formed as part thereof and
curved inwards and outwards and so bent or shaped, for the purpose of guiding or
enabling the Scraper and Tube brush combined when in action entering the Tubes
and permitting of its easy return when passed through or yielding when required
in its passage on entering and passing through the Tubes when opposed to any
undue scale or corrosion and yet capable to expand or give outwards and clear all
obstacles in its passage to and fro, and without the intervention of any internal
spring or springs so that there is no tendency for the scraper to choke or get out
of order and the refuse permitted to be afterward acted upon as hereafter
described.
In connection with the curved guard or arms as described and at the end of the
frame forming part thereof I bend the same so that the end may have a screw
tapped therein into which a spindle rod is capable of being screwed and firmly
secured with a washer and bolt or nuts so that the scraper with the frame and
elongated curved arms or guard to which it is fixed are firmly screwed up to and
attached to the rod or spindle.
Immediately behind the aforesaid Tube scraper and elongated curved guard arms
and frame I provide and fix in a suitable manner a series of curved or spiral brushes,
either continuous or in segments arranged and securely fixed upon the spindle or
rod of a suitable form and material and of sufficient length and diameter according
to the surface and extent of the Tubes to be acted upon, and at the rear or
extremity of the series of spiral or coiled brush or brushes, which may be made
either of Steel, Brass, Iron Wire, Bristles, Whalebone or other material, I provide
a cup shaped guard or washer suitably formed and capable of being screwed up on
to the thread of the rod or spindle bar by means of a nut or nuts or other equivalent
means so as to keep the brush or brushes in position and yet capable of yielding

guard or arms firmly together upon the said rod or bar, at the same time when
wholly passed through the tube enabling the same to be easily returned or
brought back.
It will thus be seen that at one and the same operation in the process of
cleansing Boiler or other Tubes by my present Invention instead of by seperate
operations of scraping and brushing as heretofore I am able to do so in a more
rapid, effectual and perfect manner as herein described and in so doing prevent
material loss or reduction of heat in the furnace and at the same time providing a
very portable and useful Tube Scraper and Brush in combination and not liable to
choke or get out of order while in use.
I provide a socket joint at the extremity of the rod or spindle bar for the hand
rod to be screwed or fixed thereto in the ordinary manner. -
In the accompanying Drawing I have shewn and exhibited my Improved Tube
Brush and Scraper, as in position of a Boiler or other Tube, wherein A represents
the scraper, which may be of other suitable shape or form and made either of Steel,
Malleable Iron or other material for the purpose intended, having a cutting edge or
lip of conical or other shape rivetted or firmly secured to a frame B formed with an
elongated curved guard or arms (as shewn) curved inwards and outwards for the
purpose of guiding or enabling it to enter the Tube C, and of sufficient elasticity
to give or yield in its passage on entering and passing through the Tubes for the
purpose of enabling it either to expand or being compressed and whilst being
opposed to any undue obstacle in the process of being forced or passed through the
Tube, and permitting immediately behind the aforesaid Tube Scraper and elongated
curved guard arms or frame B a series of curved spiral or other form or shape of
Brushes as shewn at E, either of Steel, Brass, Iron Wire, Bristles, Whalebone or
other material as may be preferred for the particular purpose, which follow in the
wake of the curved guard arms or frame B and secured upon the rod or spindle
bar F, having a cup guard or washer at the end thereof G, suitably formed and
capable of being screwed up on to the thread of the said rod or spindle bar either
by means of a nut or nuts or other equivalent means to keep the Brush or Brushes
well up in position with the Scraper A. and curved guard or arms B. I may in
some cases likewise provide a further washer at the rear of the aforesaid
frame B upon the rod or spindle bar F and secured in position in a suitable
manner.
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 as novel is the general combination of a Tube Scraper and Tube Brush
combined for clearing or cleansing and removing scale, corrosion or deposit from
the Tubes of Marine or other Boilers or Tubes generally.
