PROVISIONAL SPECIFICATION.
Improvements in or relating to the Jointing and Stopping of Pipes or
Mains.
We, WILLIAM MORLEY, of 114, Devonshire Street, Keighley, in the County of
York, Contractor, and PERCY WEST BARKER, of Highfield, Dudley Hill, Bradford,
in the same County, Engineer, do hereby declare the nature of this invention
to be as follows, that is to say:-
It relates to improvements in the method of and apparatus for forming the
joints of pipes or mains whereby such joints are rendered more thoroughly
watertight and more free from undesirable cavities and obstructions which afford
lodgment for objectionable matter than they have been as heretofore formed or
produced while the line or series of pipes are at all times brought into perfect.
concentricity with each other with the resultant advantages well understood.
In carrying our invention into effect we make use of an annular piece of
india-rubber, leather or other flexible material of a size somewhat approximating
that of the internal diameter of the pipes or mains to be joined together. This
annula pipe is secured between two discs mounted upon a screwed shaft (the
screws of which preferably lead in opposite directions, that is, one screw is right
hand and the other left hand) so that as this said screwed shaft is rotated said'
discs may be caused to approach each other to force the annular rubber radially
to assume a larger diameter and press upon the inner walls of the pipes where the
jointing of one pipe to the other is being effected, on which the plastic semiliquid
binding substance (which may consist of coal-tar and sulphur compounded and
boiled together, with any other material as sand, sawdust, cork dust or the like
for thickening or bringing same into a less fluid state) is poured into the annular
cavity formed by spigot and socket ends of the pipes, its passage through said
joining to the interior of the pipe being stopped by the flexible annular piece,
although said piece will allow it to flow and fill any irregular internal openings
that are not covered by it.
After the binding substance is thus run into position the screwed bar is
rotated to cause the discs to move apart and so free the annular piece as to enable
its easy withdrawal.
An
To secure concentricity of the screwed shaft and the pipes a guide roller is
mounted on said shaft, on the discs, for contact with the inner walls of the
pipes to hold the screwed shaft in position while it is being rotated.
appropriate handle is secured to the shaft as is also a gauge piece (which likewise
acts as a bearing) to enable the rotating of said screwed shaft and its mounting
in proper position for the annular piece to be brought into proper proximity
with the joint to form same as desired.
Instead of the screwed shaft and annular piece being employed an annular.
cavity may be formed by a flexible tube or covering being mounted upon a
metal tube having its inner end stopped and lateral or radial openings leading.
from its axial passage into the inflatable tube or covering by which means when

page_text: this latter has been placed in position within the pipes to be jointed, on air or
other gases being forced through the metal tube into the flexible one this latter
is inflated to cover the joining part as does the annular piece hereinbefore
described.
The part of our invention above described may be made use of in connection
with any or most of the common forms of -spigot and socket jointed pipes or
mains, but we preferably have the socket part of the pipe made so that on the
spigot part being inserted therein the annular cavity around it is made larger
in diameter at its middle part than it is at its orifice, so that less trouble will be
encountered when stopping or closing this latter during the running of the
binding substance therein, while on removing said stopping material, ample
space is afforded to allow the joint to be examined.
As means for stopping the outer ends or lateral branch openings in pipes or
mains we make use of the usual kind of stop-plate which we fix in position by
filling the annular space intervening between it and the socket walls of the
pipe, with clay or the like. We then place over it a metal mould which forms
an annular cavity so that the binding substance hereinbefore described may be
run to form an annular holding flange at the place desired.

Improvements in or relating to the Jointing and Stopping of Pipes or
Mains.
We, WILLIAM MORLEY, of 114, Devonshire Street, Keighley, in the County of
York, Contractor, and l'ERCY WEST BARKER, of Highfield, Dudley Hill, Bradford,
in the same County, 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, that is to say:
It relates to improvements in the method of and apparatus for forming the
joints of pipes or mains whereby such joints are rendered more thoroughly
watertight and more free from undesirable cavities and obstructions which afford
lodgment for objectionable matter than they have been as heretofore formed or
produced while the line or series of pipes are at all times brought into perfect
concentricity with each other with the resultant advantages well understood.
In order that our invention may be readily understood we have hereunto
appended sheets of drawings illustrative thereof, to which by figures and letters,
reference is made in the following description.
Fig. 1 represents a sectional elevation of our improved apparatus as when in
position for use within a pipe or main.
Fig. 2 represents an end elevation of said apparatus and pipe, as seen in the
direction of the arrow x.
Fig. 3 represents a sectional end elevation of of parts illustrated by Fig. 1,
and as seen in the opposite direction to the arrow .r.
Figs. 4 and 5 are similar views to Fig. 1 but illustrate modifications in the
construction of our improved apparatus.
Fig. 6 is a detail drawing hereinafter referred to.
Fig. 7 represents a sectional elevation of a pipe having a branch opening,
and illustrates our method of stopping the outer end of such branches.
Figs. 8 and 9 are detail drawings illustrating some of the various forms of the
outer ends of branch openings to which our invention is applicable.

page_text: Similar letters and figures of reference indicate similar parts throughout the.
several views.
In carrying our invention into effect we make use of an annular piece of
india-rubber, leather or other flexible material a of a size somewhat approxi-
mating that of the internal diameter of the pipes or mains 6 6¹ to be joined
together. The annular piece a is secured between the two discs c, c¹ which are
secured to the bearing parts d d', these latter taking over the screws e c¹ on the
shaft es, one of said screws being right hand and the other left hand, so that as
the shaft is rotated by its hand wheel or by other suitable means said
discs c, may be caused to approach each other to force the annular piece a-
radially to assume a larger diameter and press upon the inner walls of the
pipes bb where the jointing of one pipe b to the other pipe b' is being effecied, on
which the plastic semi-liquid binding substance (which may consist of coal-tar
and sulphur compounded and boiled together with any other material as sand.
sawdust, cork, dust or the like for thickening or bringing same into a less fluid
state) is poured through the openings b 68 into the annular cavity formed by
the spigot and socket ends b2b of the pipes 6 b¹ its passage through said joining
to the interior of the pipes being stopped by the flexible annular piece a, although
said piece will allow it to flow and fill any irregular internal openings that are
not covered by it.
After the binding substance is thus run into position, the bar is rotated
to cause the discs c¹ to move apart and so free the annular piece a as to enable.
its easy withdrawal.
To secure concentricity of the shaft and pipes bb and to prevent excessive
wear of the periphery of the annular piece a, a guide roller f is mounted in
bearings f which are fixed to the shaft e or to the disc c or c¹, said roller f
being for contact with the inner walls of the pipes bb'. A gauge piece g having
pegs or projections g' to rest upon the inner walls of the pipes b, is made use of
so that on said gauge piece being pressed against the end of the pipe, the annular
piece a will be in suitable proximity with the joining part to be operated upon,
while further said gauge piece 9 acts as a bearing for the shaft or rod e². In
order to prevent the annular piece and shaft from revolving together, a
shaft taking within said annular piece and through the gauge piece y and
provided with a lever arm k is made use of, so that by turning said shaft by
means of its handle until its lever arm k comes into contact with the inner walls
of the pipe b, said turning movement is prevented.
If desired we may form only one screw e¹ and movable disc on the shaft .
as shown by Fig. 4.
Instead of the screwed shaft and annular piece a being employed, an annular
cavity m may be formed by the flexible covering n being mounted between the
fixed discs o, o around the metal tube p the inner end of which is stopped,
while air supplied under pressure to said tube is enabled to enter within said
cavity m by means of the check valve 22, in this manner the covering n is
inflated and its peripheral surface forced against the inner walls of the pipes bb
to cover the joining part of the pipes as does the annular piece a hereinbefore
described. The air within the cavity m is liberated when desired by means of
the valve and opening e, said valve being operated by the rod and normally
held closed by the spring. In forming the joints of pipes or mains which are
vertically disposed, we make use of a gauge piece, of the form illustrated by
Figs. 4, 5 and 6, to reach across the mouth of the upper pipe and being provided
with projections g¹ to fit therein.
It will readily be understood that without departing from the nature of this
part of our invention, we may considerably vary the construction of the means
for operating the annular piece a, as well as the arrangement of tubes and
valves in connection with the arrangement illustrated by Fig. 5.
The part of our invention above described may be made use of in connection
with any or most of the common forms of spigot and socket jointed pipes or

page_text: mains, but we preferably have the socket part of the pipe made so that on the
spigot part being inserted therein, the annular cavity b around it is made
larger in diameter at its middle part than it is at its orifice 6º, so that less
trouble. will be encountered when stopping or closing this latter during the
running of the binding substance therein, while on removing said stopping
material ample space is afforded to allow the joint to be examined.
As means for stopping the outer ends or lateral branch openings q in pipes
or mains (see Figs. 7, 8 and 9) we make use of the usual kind of stop-piece ▸
which we fix in position by filling the annular space s intervening between it
and the socket walls ql of the pipe or the walls of the socket of the pipe bor b',
with clay or the like. We then place over it a metal mould which forms an
annular cavity so that the binding substance herein before described may be run
by means of the openings 7 73 to form an annular holding flange at the place
desired.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that
what we claim is:-
1. In the process of making joints of pipes or mains, the use or employment
of an annular piece of india rubber or like substance to take within the pipe and
capable of being expanded to bear against the joining part of the pipe sub-
stantially as herein described.
2. Apparatus for use in making joints of pipes or mains, the same being
constructed substantially as herein specified, with reference to Figs. 1, 2 and 3
of the drawings.
3. Apparatus for use in making joints of pipes or mains, the same being
constructed substantially as herein specified, with reference to Figs. 4 and 6
of the drawings.
4. Apparatus for use in making joints of pipes or mains, the same being
constructed substantially as herein specified, with reference to Fig. 5 of.the
drawings.
5. An improved spigot and socket joint for pipes or mains, consisting in
forming the central portion of the socket part of greater diameter than its ends,
substantially as herein specified.
6. Means for stopping the outer ends of pipes or mains or branch openings in
same, the same being constructed and applied substantially as herein specified,
with reference to Fig. 7 of the drawings.
