Improvements in Drain Testing Apparatus.
LAURA SHEPPARD, 12, Princes Square, Kennington Park Road, Artist, do
hereby declare the nature of this invention to be as follows:-
A metal or other suitable material tube or hollow case about 17 to 20 inches
long to hold one two or more smoke cases or drain testers any makers will do
my case is fitted with screw cap air tight on one end and with taper screw cap
on the other end this tapered end is a continuation of a smaller tube that con-
nects an indiarubber tube or material soft enough to bend through an S trap
or any other trap this can be used without taking the water out of w.c., or any
trap so that the smoke can be forced down the drain without inhaling the bad
smell. There is another spring cap at the end of the flexible tube so as to keep
the water out of the tube untill it gets through the water otherwise the water
would stop the smoke from penetrating into the drains by pulling a wire con-
nected with the spring cap that runs outside the tube opens the cap and the smoke is
forced into the drains there is a wire runs round the tube that prevents it from
flatening when the tube is forced through the S or other traps the flames from
some drain testers would if it came in contact with foul air cause an explosion
by using this machine it prevents diging the ground and breaking the pipes any
individual person can test there own drains without any trouble or inhaling the
bad smell.

LAURA SHEPPARD, 12, Princes Square, Kennington Park Road, Artist, 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, referring to the accompanying drawing;
My invention is a metal or other suitable material tube E or hollow case
about 17 to 20 inches long to hold inside; one or two or more smoke cases or
drain testers, any makers will do. My case is fitted with a screw cap F air tight
on one end and with taperd screw cap 1) on the other end this taperd end is a
continuation of a smaller tube that connects with an indiarubber tube B or any
other material suitable, soft enough to bend through an S trap or any trap.

page_text: This can be used without taking the water out of w.c., or any trap, so that the
smoke can be forced down the drain pipe. There is another spring cap A at
the end of the flexable indiarubber tube to keep the water out of the tube untill
it gets through the water, otherwise the water would stop the smoke from pene-
trating into the drain. By pulling a wire G connected with the spring cap that
runs outside of the tube that opens the cap and the smoke is forced into the
drains without any danger from bad smells which is so injuris to inhale there
is a wire C runs round the inside or outside of the flexable tube that prevents
it from flatening when the tube is forced through the S or other traps. The
flames from some drain testers would if it came in contact with foul air cause an
explosion by using this machine it prevents this danger also it prevents digging
the ground or breaking the drain pipes any individual person can test there
own drains without any trouble or inhaling the bad smells.
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:
