Improvements in Apparatus for Cementing, Staunching, and Testing
Drain-pipes without Taking up Floors or Opening up Ground in
Basement.
WILLIAM REYNOR 266 North End Road S.W. London in the County of
Middlesex Plumber & Contractor, do hereby declare the nature of this invention
to be as follows:-
I propose to have two pistons to fit drain pipe tight. Each piston is composed
of an india rubber disk between two metal plates 5 in. in diameter, which plates
can be screwed up so as to slightly alter the diameter if required. Each
piston has an extending arm in the shape of a long staple or U. The two pistons
is made to slide on a hollow tube about 2" inches in diameter and 2 ft. 6 in. long.
When the pistons are close together in centre of tube, the end of arms will be
at end of tube. A rope is then passed through tube and fixed to arm at opisite
end. A smaller rope is taken direct from each arm, so that a man working at
each end of drain can by drawing the opisite piston compress the Portland cement
which is so placed between the pistons and so force the cement into any orifice
open joint or other cause of leakage. This may be continued working from one
end of drain to the other untill the full charge remains between the pistons which
will prove there is no way of escape, and therefore may be proved with water
charge.

Improvements in Apparatus for Cementing, Staunching, and Testing
Drain-pipes without Taking up Floors or Opening up Ground in
Basement.
WILLIAM REYNOR of No. 266 North End Road S.W. in the County of
Middlesex Sanitary Engineer and Contractor, 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:-
The object of my invention is to provide facilities for staunching and testing
defective house and other drains without uncovering pipes (drain pipes) or taking
up floors of house under which they run.'"
For this purpose I provide two pistons to fit drain pipe tight each piston is
composed of an india rubber ring mounted between two metal flanges smaller
than the india rubber ring, these two flanges are so screwed together that by
tightening the screws the ring may be expanded slightly to fit the drain pipe
tight attached to one side of each flange is a copper (or other metal) hollow
tube twelve inches long, this tube's has a slightly smaller tube passing through
them freeley the rubber ring only being tightly pressed around the inner tube
a small rope is then passed from each end to opisite end and attached to the
end of larger tube attached to piston so that by drawing the opisite ropes the
pistons close together pressing out the cement previously filled in when they
were at opisite ends of smaller tube this will be continually drawn from one
end of drain to the opisite and then recharged when the charge returnes in full
it will denote that there is no defective joint to be filled and that the drain is sound.
In the accompanying drawings all the figures of which the same part is indicated
by like letters of refference the Fig. 1 is a section of the apparatus.

page_text: A. is a metal tube on which the pistons B. B haveing the larger tube CC
attached slides freeley, F is the small rope attached to ends of tube's C C and
which when both ropes are drawn the pistons B B will be drawn up to the
centre of tube A at the stop G E. E are the flanges between which the india
rubber ring d is screwed that forms the piston.
Haveing now particularly discribed and assertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is,
The combination of the diffirent parts as above for the staunching and testing
of drains substancially as described.
Dated this Thirteenth day of October 1800.
