PIPES, TUBES, OR OTHER OPENINGS
This Invention relates to an improved plug or means for temporarily or
permanently stopping up the ends or other parts of soil or ventilating pipes,
or of drains, water or gas mains, or other pipes or tubes, or manhole or other
similar openings which it may be required to temporarily or permanently stop up
or close for testing purposes by the aid of smoke or other means to detect any.
leakage. or for keeping back water, or gas, or sewage or other material or substance,
and permitting of inspection and examination of any such or like pipes or tubes,
or of repairs. or of the laying of new drains, or mains. or otherwise.
The improved plug or stopping up device comprises two principal parts, consisting
of an elastic or expansible ring which can be distended outwards, and of opposite
coned or equivalently formed parts which are encircled by such elastic ring, and
which can be brought forcibly together, and which, in being so operated upon, are
effective in causing the outward expansion of the said encircling ring, and its
forcible outward compression against the inner sides of the drain, main, pipe, tube
or other opening, thus affecting the air, gas, or water tight closure of the same.
In carrying the Invention into practical effect, there are employed two opposing
discs made of wood, iron or other suitable substance, approximating the diameter,
size, or shape, of the pipe, tube or opening to be closed or plugged up, the
peripheries of which discs are inclined, bevilled or made of an angular, or conical
formation with plane or curvilinear surfaces, and these discs are so placed as that
their conical peripheries face each other. The discs are retained in this position by
means of one or more bolts or equivalent means passing centrally or otherwise
through them. and which may be provided with a nut or nuts or a screw handle or
handles or equivalent means. so that the distance between the discs may be
regulated as desired. The V or other shaped annular space surrounding the
opposite discs is encircled by an elastic or extensible ring formed of india rubber

at their widest intended distance apart, projects just beyond the periphery or edge
of the discs. but permits of the introduction of the plug into within the tube or
opening.
Upon this being effected, the said nut or handle or other means is turned in such
a manner as to draw the opposite discs together, which causes the said clastic ring
Surrounding them to be distended outwards and forcibly compressed against the
inner sides of the pipe. tube or other opening, effectually closing the same perfectly
air, steam or water tight.

page_text: I. FRANCIS BOTTING, of Baker Street, in the County of Middlesex. Domestic
Engineer, c/o Day. Davies & lunt, Patent Agents, 321, High Holborn, in the
County of Middlesex, do hereby declare the nature of my Invention for "AN
IMPROVED PLUG OR MEANS FOR STOPPING UP THE ENDS OR OTHER PARTS OF
PIPES. TUBES, OR OTHER OPENINGS" and in what manner the same is to bo
performed to be particularly described and ascertained in and by the following
statement:
This Invention relates to an improved plug or means for temporarily or
permanently stopping up the ends or other parts of soil or ventilating parts, or of
drains: water or gas mains. or other pipes or tubes, or manhole or other similar
openings which it may be required to temporarily or permanently stop up or close
for testing purposes by the aid of smoke or other means to detect any leakage, or
for keeping back water, or gas. or sewage or other material or substance, and
permitting of inspection and examination of any such or other pipes or tubes,
or of repairs, or of the laying of new drains or mains. or of any other necessary.
purpose being carried out.
Illustrations of the application of various modifications of the improved plug or
stopping up device are given on the accompanying drawings:-In Fig: 1, it is
shown as applied to a drain for temporarily plugging and damming up water
therein to permit of its being tested or repaired. In Fig: 2. it is illustrated as
applied to a manhole-opening. In Fig: 3 as applied to a soil or ventilating pipe
for plugging up the same and permitting of its soundness being tested by the aid
of smoke or other means: and in Fig: 4. as applied to an inspection-eye of drains
for closing the same and permitting of the eye being quickly opened and closed
and repeatedly so without damage to any part thereof.
The improved plug or stopping up device comprises two principal parts, con-
sisting of an elastic or expansible ring. 1, which can be distended outwards, and of
opposite coned discs or equivalently formed parts. 2. which are encircled by such
elastic ring, and which can be brought forcibly together, and which, in being so
operated upon, are effective in causing the outward expansion of the said encircling
ring. 1. and its forcible outward compression against the inner sides of the drain.

Having now particularly described the nature and objects of my said Invention
und in what manner the same is to be performed, I declare that what I claim is :-
A plug or device for stopping up the ends or other parts of pipes, tubes or other
analogous openings, in which are combined opposite discs or their equivalents
coned or equivalently formed on their peripheries. with an elastic or expansible
ring encircling the opposite coned peripheries of such discs, and with screw bolts
and handles or equivalent means of bringing such discs forcibly together as
desired and so diametrically or outwardly distending the said encircling ring
against the inner sides of the drain, pipe. main. tube or other opening for the
purpose desired, substantially as hereinbefore described.
