nature of my invention for SCRAPING AND CLEANING CAST IRON WATER Pipes
WHILE LAID Under around to be as follows :-
My Invention consists of a two forked Square Steel Bar with scrowed end for
attaching to Iron rods for the purpose of been worked by hand.
The Bur as a number of Slot Holes in which are fixed a number of Steel Cutters
and Scrapers which can be adjusted by a Set Screw for the purpose of scraping
the insides of Cast Iron water pipes while laid under ground.

I NICHOLAS JOHN GINMAN of 2 Elor Street Horton Lane Bradford Yorkshire
Waterworks Foreman for Bradford Corporation do hereby declare the nature of
my invention for "AN APPLIANCE FOR SCRAPING AND CLEANING CAST IRON
WATER PIPES and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
"
The object of my Invention is to provide a simple and efficient apparatus by
which pipes can be readily and properly cleaned my said Invention being especially
applicable to the cleaning of cast iron water pipes whilst in position.
An apparatus constructed according to my Invention consists of a bar preferably
of steel and square in section and forked at the one end and provided at the other
end with a screw or other means for attaching rods by which the scraper can be
The said bar carries a number of breakers or
rotated in the pipes to be cleaned
cutters and scrapers (both or either) which as the bar is rotated, cut into or
separato and remove the material from the interior of the pipes..
And in order that my said Invention may be fully understood I shall now
proceed more particularly to describe the same and for that purpose shall refer to
the several figures on the annexed sheet of drawings the same letters of reference
indicating corresponding parts in all the figures.
Figures 1 and 2 are side views at right angles to each other of a pipe cleaner
constructed according to my Invention and Figure 3 is an end elevation of the
implement in a pipe. The bar A constituting the holder of the cutters or scrapers
is preferably forked at its front end a to break up and loosen deposits in the pipes
and has slots in it to receive the breaking up or cleaning and scraping tools, the
said slots being arranged preferably alternately at right angles to each other so
that the series of cutters or scrapers can be set in a helical or screw-like direction
around the bar A-The tools used may be of any suitable shape which will allow
of their being fixed firmly to the bar A, and which will be suited to give the
requisito breaking up and clearing action upon the deposit in the pipes. Figure 4
shews a tool suited for being mounted towards the front end of the bar A for
assisting in breaking up and loosening the deposit. I have shewn two of these
tools fixed in position but one or any suitable number may be used. Figure 5
shews a tool suitable for scraping out the deposit, of which tools also any suitablo
number may be used. I have shewn four of these scrapers attached to the bar A,
arranged in a helical or screw-like manner so that they follow each other in
action-The tools are shewn as being fastened to the bar A by their shanks being
passed into the slots in the said bar and secured by screws c-Lengths of pipe or
rods B are screwed or otherwise fastened (for example by slots and cotters) to the
bar A) springs b being provided to keep the tool holder in its proper position in
the pipe. Figure 6 is a bandle suitable for placing on the end of the bar or of the
lengths of rod for turning the tool in the pipes. Figures 7 and 8 are side views at
right angles to each other of a larger machine which is constructed. and used in
substantially the same manner as is that hereinbefore described but in this case

page_text: in place of using the loosening and scraping tools upon the bar, both at the same
time, pointed or pronged tools or forks with any suitable number of points, such
for example as are shewn in figure 9 may be first used to break up the deposit and
then the said tools may be removed and others, such for example as those shewn in
figure 10 may be substituted therefor for cutting and scraping off the deposit.
Figure 11 is a transverse section of a pipe shewing the implement in end view.
The mode shewn of affixing the tools to the bar A enables the tools to be adjusted
to suit different diameters of pipes.
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 is
An Apparatus for clearing or cleaning pipes consisting of a bar fitted with
breaking up or scraping tools or both and provided with means for operating it
substantially as heroin before described.
