Improvements in Tube Cleaners and Scrapers
I, FREDERICK WILLIAM SHOREY, of 5 Pennyfields, Poplar, London, E.
Maine Engineer. (a communication from William Henry Shorey of Parham, .
Antigua, Bitish W. Indies), do hereby declare the nature of this invention to be
as follows
My invention relates to an improved form of construction which I employ when
making cleaners and scrapers for use in steam boiler, condenser and like tubes
In caying my invention into effect 1 employ any well known form of rol and
joint attachment and I secure to the end or front rod or head a springing holder
having projecting guides or hoins arranged thereupon which enter the tube in
advance of the cutters or cleaner- At the end of the holle o carier I place
two or more cutters having a enculan perphery for fitting the interior of the Lube.
These cucular disc like or segmental cutters I provide with V shaped or semi-
cncular grooves,
the edges of which form cutting surfaces oi eleaming surfaces for
effectually scraping the interior of the tube.
1 may make my cutters in the form of two semi-cncular plates each plate having
its cutting surfaces formed by means of one or more grooves provided therein or
I may arrange three or
more segments upon the springing or expanding and
contracting holder.
1 attach my cutters to the springing holder by incans of screws, livets or by any
other suitable arrangement; and I vary the shape of the holder and guides to suit.
my special requirement.

Improvements in Tube Cleaners and Scrapers.
I, FREDERICK WILLIAM SHOREY, of 5 Pennyfields, Poplar, London E.,
Marine Engineer (a communication from William Henry Shorey, of Parham,
Antigua, British W Indies) 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 relates to an improved form of construction which I employ when
making cleaners and scrapers for use in steam boiler, condenser and like tubes.
Refering to the accompanying sheet of explanatory diawings-
Figure 1 is a side elevation of a tube cleaner or scraper made in accordance with
my invention, while Figures 2 and 3 are respective plan and end elevation
corresponding thereto.
Figure 4 is a side elevation of a constructional modification.
In carrying my invention into effect 1 employ any well known form of 10d and

page_text: Joint attachment and secure to the end or front rod o head a springing holder A
having projecting guides oi hoins C C arranged thereupon which enter the tube in
advance of the cutters or cleaners D D. At the end of the bifurcated springing
holder or carrier I place two or more cutters D D having a cucular periphery
for fitting the interior of the tube. These circular disc like or segmental
cutters DDI provide with V shaped or semi-circulai grooves, the edges of
which form cutting surfaces or cleaning sun faces for effectually scraping the
interior of the tube.
I may make my cutters in the form of two semi-circular plates d d each plate
having cutting surfaces formed thereon, and secured to the ends of the bifurcated
springing holder or carrier A, which are formed to receive them, or I may arrange
thice or more segments upon the springing or expanding and contracting holder,
in which case the holder may be formed of thicc or more springing arms.
I may
form my cutters as segmental plates having a grooved periphery as shown at d
(Figure 4) or I may form the extremity of the arms of the holder or carrier as
segmental discs and secure thereto other segmental discs of the same configuration,
the faces of the respective peripheries being opposed, as shown at B (Figure 4).
I attach my cutters to the springing holder by means of screws, rivets or by
any other suitable arrangement, and I vary the shape of the holder and guides to
suit any special requirement.
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―
1. In tube cleaners or scrapers the provision of segmental cutting or scraping
plates or cutters upon outwardly springing holder arms substantially as described
2. Improvements in tube cleaners oi sciapers substantially as herem described.
