PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Cleaning the Interior of Boiler
Tubes and other Tubes.
We, JOHN PLATT, of the firm of Mather and Platt, of Salford Iron Works,
Manchester, in the County of Lancaster, Engineer and THOMAS THORP, of the
same place, Manager, do hereby declare the nature of this invention to be as
follows:-
Our invention relates to improvements in apparatus for cleaning the interior
of the tubes employed in steam boilers as well as other tubes employed in
manufacturing processes.
Our improved apparatus is composed of a number of cutters bedded on an elastic
foundation the cutters and the foundation being supported between two metal collars
or ends the whole being mounted upon a suitable stem or handle. Each cutter is
formed with teeth or serrations either straight or bevelled on its outer face and each
cutter is preferably bedded on its elastic foundation with its cutting edges facing in
the opposite direction to that of the cutting edges of the cutters on each side
of it.
When the apparatus is placed inside a tube and moved backwards and forwards
either by hand or power the cutters scrape and clean the deposit from the interior of
the tube, the elastic foundation permitting the cutters to yield when they encounter
the seams or other hard inequalities in the tube.
In order to make the apparatus more effective steam or other fluid under pressure
may be applied to the interior of the elastic foundation so as to keep the cutters
expanded against the interior of the tube.

Improvements in Apparatus for Cleaning the Interior of Boller
Tubes and other Tubes.
We, JOHN PLATT, of the firm of Mather and Platt, of Salford Iron Works,
Manchester, in the County of Lancaster, Engineer, and THOMAS THORP, of the same
place, Manager, do hereby declare the nature of this said invention and in what manner
the same is to be performed to be particularly described and ascertained in and by
the following statement :-
Our invention relates to improvements in apparatus for cleaning the interior
of the tubes employed in steam boilers as well as other tubes employed in
manufacturing processes.
Our improved apparatus is composed of a number of cutters bedded on an elastic
foundation the cutters and the foundation being supported between two metal collars
or ends the whole being mounted upon a suitable stem or handle. Each cutter is
formed with teeth or serrations either straight or bevelled on its outer face and each
cutter is preferably bedded on its elastic foundation with its cutting edges facing in
the opposite direction to that of the cutting edges of the cutters on each side
of it.
And in order that our invention may be fully understood and readily carried into
effect we will describe the accompanying Sheet of Drawings reference being had to
the figures and letters marked thereon.

page_text: Figure 1 is a longitudinal section of a tube cleaner constructed according to our
invention and Fig. 2 is a transverse section on the plan of the lino A B, Fig. 1.
In these views a designates the cutters which are bedded on a tube or
foundation of elastic or yielding material. The rows of cutters a are confined
between the two metal collars cc which are screwed upon or otherwise secured to a
handle on which is also screwed a nut e. The handled in this instance is shown as
a hollow stem or tube for the purpose hereinafter described.
In
When the apparatus is placed inside a tube and moved backwards and forwards
either by hand or power applied to the handled the cutters a scrape and clean the
deposit from the interior of the tube, the elastic foundation permitting the cutters
to yield when they encounter the seams or other hard inequalities in the tube.
order to make the scraping and cleaning action of the apparatus more effective
steam or other fluid under pressure may be supplied through the hollow stem d and
passing through the aperture 2 to the interior of the elastic foundation thereby
expands the latter and so keeps the cutters a expanded against the interior of the
tube.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
=-
1- The improved tube cleaner having a series of cutters or scrapers supported on
an elastic foundation capable of expansion by the application of fluid under pressure
substantially as and for the purposes herein set forth.
2. The combination with the cutters a supported between metal collars c c on a
hollow stem or handle such as d, of the clastic bed or foundation & substantially as
and for the purposes herein set forth.
