PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Clearing Drains and other Pipes.
FREDERICK CHARLES LYNDE 25 Cross Street Manchester Civil and Sanitary
Engineer, do hereby declare the nature of this invention to be as follows:-
My invention consists in the use and manufacture of an improved apparatus for
clearing drains or other pipes internally of luting material used in making the
joints or deposit or obstruction.
Upon a flexible core I mount one or more discs or their equivalents holding a
ring or rings of india rubber or other suitable material.
The apparatus thus formed is to be used for passing through pipes for removing
from the interior foreign matter and especially luting material used in making the
joints. I may attach a scraper formed of thin pieces of steel or wire or other
suitable material to a flexible core or combine it with the above described
apparatus
or I may form a support or supports for the core and disc or discs by adjustable
studs or projections or other means which will enable a disc or discs or their
equivalents to be held in a concentric or nearly concentric position within the
pipe.
These discs may carry the ring or rings of india rubber or other material in such
a manner as shall provide for the wearing away of the same and may be loose
within or upon the disc or discs or weighted or provided with springs or other
means of causing adjustment. I may also construct rings of wire, coiled wire, or
flattened wire so as to scrape the internal surface and be capable of adjustment.
I may place the clearing material spirally or in a zigzag form or in plain circles
upon its foundation.
Improvements in Apparatus for Clearing Drains and other Pipes.
FREDERICK CHARLES LYNDE 25 Cross Street, Manchester Civil and
Sanitary Engineer, 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 consists in the use and manufacture of an improved apparatus for
clearing drains or other pipes internally of luting material used in making the joints
or deposit or obstruction.
Upon a flexible shaft I mount one or more discs or their equivalents holding a
ring or rings of india rubber or other suitable material.
The nature of my invention and the manner in which the same is to be carried
into practical effect will be readily understood on reference to the drawing
annexed.
Fig. 1 is an elevation one half of which is shewn in section and
Fig. 2 is an end view of the apparatus.
The discs A. A. provided with indiarubber ring or rings C C C are mounted
upon the flexible shaft B. B. which is provided with a loop or hook to which a chain

page_text: Upon drawing the discs over a joint within a drain, the cement or other jointing
material which may be within the pipe is dislodged and drawn forward and thus
the absence of obstruction within the drain is insured.
Instead of indiarubber it is obvious that metal coils or wires may be used.
Having now particularly described and ascertained the nature of my inven-
tion I declare that what I claim is :-
The improved apparatus for clearing drains and other pipes substantially as
hereinbefore described and illustrated in the drawings annexed.
Dated this Eleventh day of February 1895.
