A NEW OR IMPROVED APPLIANCE FOR FORMING on MOULDING SYPHON AND OTHER BENT PIPES OR STENCH TRAPS
Year: 1871

page_text: LETTERS PATENT to Henry Sutcliffe, Plumber, and Wright Sutcliffe,
Weaver, both of Halifax, in the County of York, for the Invention
of "A NEW OR IMPROVED APPLIANCE FOR FORMING on MOULDING SYPHON
AND OTHER BENT PIPES OR STENCH TRAPS."
Sealed the 12th January 1872, and dated the 14th July 1871.
PROVISIONAL SPECIFICATION left by the said Henry Sutcliffe and
Wright Sutcliffe at the Office of the Commissioners of Patents,
with their Petition, on the 14th July 1871.
We, HENRY SUTOLIFFE, Plumber, and WRIGHT SUTCLIFFE, Weaver,
both of Halifax, in the County of York, do hereby declare the
nature of the said Invention for "A NEW OR IMPROVED APPLIANCE FOR
FORMING OR MOULDING SYPHON AND OTHER BENT PIPES OR STENCH TRAPS,"
to be as follows:-
In the construction of syphon and other bent pipes or "stench traps"
for preventing the escape of noxious gases from sewers and waterclosets,
the practice heretofore has been to form such of sheet lead, each half

page_text: of a pipe being beaten or blocked to the shape required, the two halves
are then secured together by soldering; or such pipes have been cast
round a core, the core being afterwards broken within the pipe as the
only means of removing the same, both these plans are costly and the
pipes so made are weak and faulty.
In constructing such pipes according to our Invention, we employ
a pair of metal moulds; these moulds are of the form required to produce
one half of a pipe, and the moulds are placed one within the other, leaving
a space between the two equal to the thickness of the pipe required.
One of the moulds is attached to a bed plate, the other is provided
with levers for drawing apart the moulds; the lead is poured between
the moulds from a lead pan, the "lip" of which is made of considerable
breadth rapidly discharging the lead to the mould, so as to prevent
chilling, a "skimmer" being placed across the lip to prevent impurities
passing with the lead to the mould, and thus one half of a pipe is
formed. The corresponding half is to be made in the same manner, and
the halves secured together by soldering. The use of the moulds
not only considerably reduces cost of production of such pipes, but
the pipes so made are much stronger because additional metal is given
at the points where most required, that is to say, at the bent portions
thereof.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry Sutcliffe and Wright Sutcliffe in the Great
Seal Patent Office on the 13th January 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, HENRY
SUTCLIFFE, Plumber, and WRIGHT SUTCLIFFE, Weaver, both of Halifax,
in the County of York, send greeting.
"
WHEREAS Her most Excellent. Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourteenth day of July, in the year
of our Lord One thousand eight hundred and seventy-one, in the
thirty-fifth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said Henry Sutcliffe and Wright Sutcliffe,
Her special licence that we, the said Henry Sutcliffe and Wright
Sutcliffe, our executors, administrators, and assigns, or such others as

page_text: we, the said Henry Sutcliffe and Wright Sutcliffe, our executors,.
administrators, and assigns, should at any time agree with, and no.
others, from time to time and at all times thereafter during the term.
therein expressed, should and lawfully might make, use, exercise, and:
vend, within the United Kingdom of Great Britain and. Ireland, the
Channel Islands, and Isle of Man, an Invention for "A NEW OR
IMPROVED APPLIANCE FOR FORMING OR MOULDING SYPHON AND OTHER BENT
PIPES OR STENCH TRAPS," upon the condition (amongst others) that we,
the said Henry Sutcliffe and Wright Sutcliffe, our executors or admi-
nistrators, by an instrument in writing under our, or their, or one of
their hands and seals, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to
be performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date
of the said Letters Patent.
NOW KNOW YE, that we, the said Henry Sutcliffe and Wright
Sutcliffe, do hereby declare the nature of our said Invention, and in
what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement and two accompany-
ing Sheets of Drawings (that is to say) :-
In the construction of syphon and other bent pipes or "stench traps"
for preventing the escape of noxious gases from sewers and waterclosets,
the practice heretofore has been to form such of sheet lead, each half
of a pipe being beaten or blocked to the shape required, the two
halves are then secured together by soldering; or such pipes have been
cast round a core, the core being afterwards broken within the pipe
as the only means of removing the same; both these plans are costly
and the pipes so made are weak and faulty.
In.constructing such pipes according to our Invention we employ a
pair of metal moulds; these moulds are of the form required to produce
one half of a pipe, and the moulds are placed one within the other,
leaving a space between the two equal to the thickness of the pipe
required. One of the moulds is attached to a bed plate, the other is
provided with levers for drawing apart the moulds. The lead is poured
between the moulds from a lead pan, the "lip" of which is made of
considerable breadth, rapidly discharging the lead to the mould, so

page_text: as to prevent chilling, a " skimmer" being placed across the lip to
prevent impurities passing with the lead to the mould, and thus one
half of a pipe is formed. The corresponding half is then to be made
in the same manner, and the halves secured together by soldering. The
use of these moulds not only considerably reduces cost of produtcion of
such pipes, but the pipes so made are much stronger because additional
metal is given at the points where most required, that is to say, at the
bent portions thereof.
Such being the nature and object of this our said Invention, we will
now proceed to describe the same in detail, and in order that the
Invention may be clearly understood, we have hereunto annexed two
Sheets of Drawings, and have marked the same with figures and letters
of reference, the same letter referring to the same part in the various
views or figures.
".
At Fig. 1 is shewn a pair of moulds A and B, and mould A is attached
to a bed plate or even surface plate C by bolts or pins D, the lead being
supplied to the moulds at or through the apertures or "pocket
holes" E, E, by or from lead pans, provided with a "lip" about equal
in width to the length of the said " pocket" "holes," so as to rapidly
discharge the lead from the pans to the moulds, and thereby prevent
chilling. At F, F, are holes in the bed plate, in which levers or rods
are inserted so as to afford means of "purchase' or leverage against
the lugs or projection G, G, for separating the moulds. At Fig. 2 is
shewn moulds detached, the mould A being partly in section.
Fig. 3 is shewn a mould for casting the corresponding half of pipe
to that made by the mould shewn at Fig. 1. At Fig. 4 is shewn tho
same moulds as at Fig. 3, opened or separated, the mould A being
partly in section. At Fig. 5 is end view of part of mould, shewing the
"lock" H, for strengthening the pipes at the bent or curved portion
thereof. At Fig. 6 is shewn a pair of moulds of another form; and
Fig. 7 is an internal view of the mould A.
At
Having thus fully described the nature and object of this our said
Invention, together with the manner in which the same is to be or
may be performed or carried into practical effect, we would have
it distinctly understood, that we claim as of our Invention is, the
appliance for forming or moulding syphon and other bent pipes or

page_text: stench traps as herein described and illustrated in the accompanying
Drawings.
In witness whereof, we, the said Henry Sutcliffe and Wright
Sutcliffe, have hereunto set our hands and seals, this Eleventh
day of January, in the year of our Lord One thousand eight
hundred and seventy-two.
