Improvements in the Method of and Means employed for Connecting
or Joining Metal Pipes.
I, BENJAMIN GREENWOOD SMITH, of Stannary Street, Halifax, in the County
of York, Brass and Iron Founder, do hereby declare the nature of this invention to
be as follows:-
This invention relates to improvements in the method of and means employed for
uniting or joining the ends of metal pipes, the object being to unite the pipes by
soldering, and without the employment of putty or any kind of packing, and to
ensure such joint being perfectly tight and secure, and the invention consists in the
combination of an iron pipe, to the end of which is cast a short length of lead pipe,
which latter is to be inserted into the leaden pipe to which it is to be connected,
and then soldered thereto, i.e. lead soldered to lead.
According to this invention, the end of one pipe, as for instance, a fall pipe, is
flanged. and recessed, and to this end is cast a short length of lead pipe, the flanges
and recesses or projections preventing the short length of lead pipe being either
pulled off or turned on the iron pipe.
The short length of lead pipe is placed inside the lead trap or pipe to which it
is to be connected, and the two are then soldered together, and a perfect and secure
joint is the result..
Dated this 22nd day of January 1895.

Improvements in the Method of and Means employed for Connecting
or Joining Metal Pipes.
I, BENJAMIN GREENWOOD SMITH, of Stannary Street, Halifax, in the County
of York, Brass and Iron Founder, 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 relates to improvements in the method of and means employed
for uniting or joining the ends of metal pipes, the object being to unite the pipes
by soldering, and without the employment of putty or any kind of packing, and
to ensure such joint being perfectly tight and secure; and the invention consists in
the combination of an iron pipe, to the end of which is cast a short length of lead
pipe, which latter is to be inserted into the leaden continuation pipe to which it is
to be connected, and then soldered thereto, i.e., lead soldered to lead.
According to this invention, the end of one pipe, as for instance, a fall pipe, is
flanged and recessed, and to this end is cast a short length of lead pipe, the flanges
and recesses or projections preventing the short length of lead pipe being either
pulled off or turned on the lead pipe.

page_text: The short length of lead pipe placed inside the lead trap or pipe to which it.
is to be connected, and the two are then soldered together, and a perfect and secure
joint is the result.
Such being the nature and object of my said invention, the following is a
complete description of same, reference being had to the accompanying drawings,
in which :-
Fig. 1 is an illustration of my invention as applied to a branch pipe such as
commonly used in connection with water closets.
Fig. 2 is an illustration of similar pipe, before the lead addition.
Fig. 3 is a section on line A. B. of Fig. 2.
Fig. 4 is longitudinal section of a length of pipe having the lead part applied
thereto, according to this invention, and drawn on enlarged scale.
At 1 is the ordinary vertical or fall pipe, the arm 2 of which has at its junction
end a series of circular recesses 3, 4 and rings 5, 6, 6, into and between which the
molden lead forming the junction length 7 runs. There are also the divisional
pieces 8 cast between the rings 5, 6, the parts 8 serve to prevent the added
portion or junction length 7 from turning round. The bead 7 gives additional
strength to the joint.
The junction is, by means of the molten lead running into the recesses 3,4
between the rings, and by reason of the divisional pieces 8, locked fast and
immovable to the arm or bend 2. The lead junction length 7 may be cast in chill
moulds around the iron pipe, or by means of running the lead round the end of the
junction, or other pipe, when laid in moulders sand, or otherwise.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is
The improvements in pipe joints comprising an intervening length of leaden
pipe connected to an iron pipe, by means of casting the latter to the iron pipe and
affixing it by means of the locking devices, as illustrated by the annexed drawings
and as herein fully described.
