PROVISIONAL SPECIFICATION.
Improved Drain Plug.
1, MILTON SYER, of Hanover Works, Peckham, in the County of Surrey,
Merchant, do hereby declare the nature of this invention to be as follows :-
I provide a hollow tube screwed on the outside with a flange fixed on one end,
next to this flange is placed a loose india rubber ring of proper size and thickness,
then I place another loose metal flange which is kept in its place by a running nut.
After which comes the bar or bridge, the use of which is to lay across the open
end of drain pipe so that the running screw handle can be screwed up against the
bridge and so tighten up the rubber flange against the side of drain pipe and make
a perfect sound plug.
The cap is screwed on the end of pipe to allow the confined water to pass after
the cap is taken off and the drain has been tested. With this drain plug various
sizes of pipes can be plugged and tested as I supply india rubber rings and metal
flanges to fit any desired pipe the whole being interchangable. I sometimes use a
moulded rubber ring but can use an ordinary flat ring. I provide india rubber
flanges with the metal flanges connected together so as to avoid the possibility
of parts being lost, so that one apparatus can be used for any number of different
sized drains, by means of interchangable plugs.

COMPLETE SPECIFICATION.
Improved Drain Plug.
I, MILTON SYER, of Hanover Works, Peckham, in the County of Surrey,
Merchant, 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 relates to an improved drain plug.
The object is to provide a plug of various sizes for the purpose of stopping
drains when the same is being tested.
And in order that my invention may be thoroughly understood, I now proceed to
describe the accompanying drawing thereof, reference being had to letters and
figures marked thereon.
Fig. 1, is a vertical section of the apparatus.
Fig. 2, is an elevation.
Fig. 3, is a plan of the top.
Fig. 4, is a plan of the bottom.
This invention is constructed with a hollow tube a (or a solid stem); screwed on
the outside at the base up to a shoulder with a male screw, and to this said screw
is attached a double flanged sunk circular plate b. The double flanged sunk
circular plate b is tapped in the centre with a female screw and may be constructed
of one or more plates. Between the top and bottom flanges of the double flanged
sunk circular plate b in the recess or groove e is placed an india rubber ring c of a
proper size and thickness and of any suitable section. On the top of the hollow
tube a is a cap and boss with four projecting arms d the whole being cast in one
Pin1

page_text: piece, the aforesaid boss and arms form the handle for screwing or unscrewing the
hollow tube a from the double flanged sunk circular plate, or for forcing the plug
down the mouth of a drain pipe.
The hollow tube or stem a may be unscrewed from the double flanged sunk
circular plate 6 to allow the confined water to pass after the drain bas been tested.
If preferable a union may be fitted to the cap and boss.
With this drain plug various sizes of pipes can be plugged and tested as I supply
india rubber rings c and double flanged sunk circular plates b to fit any desired
pipe the whole being interchangable. I sometimes use a moulded rubber ring but
can use an ordinary flat ring as in Figs. 1, and 2.
It will be understood that the foregoing is given by way of illustration, and that
the shapes materials and proportions of the parts may be varied in many ways
within the scope of my invention.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In pipe plugs for testing pipes, the combination of the hollow tube or stem a
with a shoulder and a male screw at the base and a cap and boss with four projecting
arms & at the top, and the double flanged sunk circular plate b or plates with a
recess or groove e to receive an india rubber ring c, substantially as herein described
and according to the accompanying drawing.
2. In pipe plugs for testing pipes, the combination of a double flanged sunk
circular plate 6, the recess or groove e, and the india rubber ring e, attached to a
stem, substantially as herein described and according to the accompanying
drawing.
3. In pipe plugs for testing pipes, the combination of the apparatus constructed
with india rubber rings of any section fitted to double flanged circular plates of
various sizes and being interchangable on one stem, substantially as described and
for the purpose specified.
