Improved Method of and Apparatus for Coupling or Connecting Lead
or Composition Pipes to Pipes, Taps, and the like, also for Stopping
such Pipes.
I, FREDERIC GEORGE SISON HAM, of 13, Grosvenor Road, Westminster, London,
Engineer, do hereby declare the nature of this invention to be as follows:
-
This invention has for object, means for coupling or connecting or stopping
the ends of lead or composition pipes without the employment of solder or
pressed joints (socket or wiped) such as are used by plumbers, gas fitters, and
others.
For the purpose of my invention, I fit a plain tapered or corrugated nozzle,
in the end of one or in the ends of both pipes to be connected, and by a collar
or ferrule on the outside of such pipe or pipes I cause the lead or compo pipe
to fill the space between either in a plain manner, or with recesses, or overlaps,
or burred down extensions, one or each of which forms a bed or touch bed for the
opposite nozzle or ferrule to make a watertight or gastight scam, the soft metal
being more or less compressed for that purpose.
In some cases, a plain collar and a corrugated ferrule can be employed, and
the lead or compo pipe be pressed into the corrugations by an expander tool
or roller and die.
The adjoining ends of two pipes can be similarly prepared and the union may
be by a screw or other jointing.
In some cases, the collar or the ferrule may be stepped and a portion of the
swelled out end of a pipe (or pipes) be made to fit.
The collars or the ferrules may be ribbed and after insertion into the swelled.
out ends of the lead or compo pipe, such end or ends can be crushed or clamped
upon them to prevent twist, such a collar if screw threaded on the inside could.
be used in conjunction with a threaded extension of the adjoining collar and
these with the burred in or burred over portion or portions of the pipes would
make the seam water or gastight without an outer ferrule, but I prefer to use
a ferrule or a couple of them for extra security, especially where the pressure
is high.
For water main supply, the ferrule is preferably screw threaded for receiving
a screw collar of, say, a tap such as a stop cock, and the same is applicable for
ordinary water draw off taps and others of the screw down or plug arrangements.
The faces of the burred down or burred over end or ends of the pipe may be
channelled for a rubber or other ring to serve as packing.
By this invention, the original bore of the piping need not be reduced.

I, FREDERIC GEORGE SISON HAM, of 13, Grosvenor Road, Westminster, London,
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:-
This invention has for object, means for coupling or connecting or stopping
the ends of lead or composition pipes without the employment of solder or
pressed joints (socket or wiped) such as are used by plumbers, gas fitters, and
others.
For the purpose of my invention, I splay out to cone shape the end or ends of
soft metal pipes, within which I fit a plain tapered or corrugated ferrule or
nozzle, and by a ferrule on the outside of such pipe or pipes I cause the lead
or compo pipe to fill the space between either in a plain manner, or with recesses
or overlaps, or burred down extensions, one or each of which forms a bed or
touch bed for the opposite nozzle or ferrule to make a watertight or gastight
seam, the soft metal being more or less compressed for that purpose.
In some cases, a plain collar and a corrugated ferrule can be employed, and
the lead or compo pipe be pressed into the corrugations by an expander tool
or roller, and die.
The adjoining ends of two pipes can be similarly prepared and the union may
be by a screw or other jointing.
In some cases, the collar or the ferrule may be stepped and a portion of the
swelled out end of a pipe (or pipes) be made to fit.
The collars or the ferrules may be ribbed and after insertion into the swelled
out ends of the lead or compo pipe, such end or ends can be crushed or clamped
upon them to prevent twist, such a collar if screw threaded on the inside could
be used in conjunction with a threaded extension of the adjoining collar and
these with the burred in or burred over portion or portions of the pipes would
make the seam water or gastight without an outer ferrule, but I prefer to use
a ferrule or a couple of them for extra security, especially where the pressure
is high.
For water main supply, the ferrule is preferably screw threaded for receiving
a screw collar of, say, a tap such as a stop cock, and the same is applicable for
ordinary water draw off taps and others of the screw down or plug arrangements.
The faces of the burred down or burred over end or ends of the pipe may be
channelled for a rubber or other ring to serve as packing.
By this invention, the original bore of the piping need not be reduced.
My invention will be fully understood by reference to the annexed drawings.
Figure 1 part sectional elevation of a bib branch connection affixed to the
end of a lead, a compo, or other soft metal pipe.
Figure 2 shows the end of a soft metal pipe prepared with internal and external
cone shaped ferrules, the ends of the soft metal pipe being flush with the faces
of the ferrules and having the body splayed out cone fashion and then expanded
by a separate tool to engage in the annular recesses of the ferrule.
Figure 3 part sectional elevation of soft metal pipe end having an outside
ferrule and an internal plug forming part of the screw on cap which screws on
the flange of the ferrule as a closer to the end of said pipe which is here shown
spread outwardly to give a broad abutment against the packing washer and

page_text: ensure a tight joint when the cap is screwed home and the outer ferrule drawn
into close contact due to the resistance offered by the plug.
Figure 4 shows the end of the soft metal pipe drawn or hammered down upon
the broader end of the inner ferrule and with the outer cone ferrule having a
serrated inner face, the burred over end portion of the soft metal pipe forming
an abutment for the bearing of similarly fitted end of a pipe to be connected to
it for extending the length.
Figure 5 represents a similar section with the end of the soft metal pipe burred
down inwardly upon a stepped inner cone ferrule, said burred over part of the
soft metal pipe having an annular channel formed in its face for the insertion
of a rubber or other packing ring if such be found necessary. This figure shows.
an internally screw threaded collar over the flange of the outer ferrule for making
the connection of the ends of the two pipes in a manner shown at Figures 1
and 6 which represent my joint complete.
Figure 7 shows a stop tap provided at each end with my outside cone shaped
ferrules and with screw threaded collars for the ready attachment of the ends of
soft metal pipes prepared with spread open ends, over which the outer ferrules
can be first placed, so that the collar can draw the parts together and make water
or gastight connection without requiring a soldered or a plumber's wiped joint.
Figure 8 represents an union joint for application to splayed out ends of
pipes as before described.
The only tool necessary for a workman to be possessed of is one or two spiles
such as I show at Figure 9 consisting of a hard wood spile to be driven into the
end of a soft metal pipe until the pipe opens out and up the coned portion of
the spile after the outer ferrule is slipped over the pipe end, the inner ferrule
is then inserted to be flush with said end, or it may be driven in to enable the
burred over part to be made for the coupling of the two ends to be effected.
It will be observed that by splaying the ends of the pipes for the reception
of the inner ferrules in the manner explained, the bore of the pipe is not reduced,
the central passage of the inner ferrule corresponding therewith.
A, A, soft metal piping. B, B, inner ferrules. C, C, outer ferrules. D, screw
collar. E, inwardly or outwardly burred over portion of soft metal pipe A.
1, annular channel in face of burred over part for packing ring. G, plug of closer
cap H. I, packing ring in said cap H.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1. As means for closing or connecting the ends of soft metal pipes A, the
employment of inner ferrules B, and outer ferrules C, between which splayed
out ends of the pipes A can be clamped, as and in the manner specified and
substantially as represented on the annexed drawings.
2. As closing appliances for the end or ends of soft metal pipe or pipes, an
internal coned ferrule, an external coned ferrule between which ferrules the
end or ends of a pipe or pipes can be secured, either for extension connections or
for closing same, as described and substantially as shown.
