PROVISIONAL SPECIFICATION.
Improvements in or connected with the Casting and Fusing of
Auxiliary Parts to Articles Formed of Lead or other like
Metal.
We, THOMAS CLAUGHTON, JOHN WILLIAM CLAUGHTON, and JAMES HENRY
CLAUGHTON, all of the Firm of Claughton Brothers, of Stanningley near Leeds,
in the County of York Plumbers and Lead Founders, do hereby declare the nature
of this invention to be as follows:-
The object of our invention is to construct auxiliary projecting parts on lead
articles in such a manner that they become homogeneous with or form part of the
main article.
Hitherto it has been necessary when adding a flange or other part to an article
already manufactured, to first construct the flange or other part and then to burn
or otherwise attach same to the main article. This process occupied a consider-
able amount of time and consequently was very expensive, whilst at the same time
the parts when connected together were not always of the required strength.
According to our invention, we attach a mould to the main article in such a
manner that a portion of the main article is exposed in the interior of the said
mould. The mould is provided with two spouts, the upper ends or mouths of
which are above the level of the interior of the mould. A valve is provided on
each of the spouts between the mouth and the mould, the said valves communi-
cating with the exterior or other suitable overflow.
The molten metal is poured in at the mouth of one of the spouts, filling the
mould and rising up the other spout until it arrives at the valve, which being open
allows of the overflow of the metal. After pouring for a short time to allow of
the fusing of the metal composing the main article, against which the molten
metal has come in contact, the valve in the last mentioned spout is closed, and the
opposite valve is opened. The molten metal is now poured in at the mouth of the
second spout and runs through the mould and out at the opposite overflow valve,
filling up any remaining space in the mould and completing the fusion of the
adjacent part of the main article.
By the above described process, the new metal combines and mixes with the
metal forming the main article, and in solidifying the new or added auxiliary part
becomes homogeneously united therewith.
In some cases a single "pouring" may be found sufficient for fusing the adjacent
part of the main article and amalgamating same with the new metal, when one
inlet spout only is required.
Our invention will be found particularly applicable for adding flanges to tubes
already constructed, or for adding short auxiliary tubes to main tubes, or making
other additions of a like nature.

Auxiliary Parts to Articles Formed of Lead or other like
Metal.
We, THOMAS CLAUGHTON, JOHN WILLIAM CLAUGHTON, and JAMES HENRY
CLAUGHTON, all of the Firm of Claughton Brothers, late of Stanningley but now
of Bramley both near Leeds, in the County of York, Plumbers and Lead
Founders, 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 :-
The object of our invention is to construct auxiliary projecting parts on lead
articles in such a manner that they become homogeneous with or form part of the
main article.
Hitherto it has been necessary when adding a flange or other part to an article
already manufactured, to first construct the flange or other part and then to burn
or otherwise attach same to the main article. This process occupied a consider-
able amount of time, and consequently was very expensive whilst at the same time
the parts when connected together were not always of the required strength.
According to our invention, we attach a mould to the main article in such a
manner that a portion of the main article is exposed in the interior of the said
mould. The mould is provided with two spouts, the upper ends or mouths of
which are above the level of the interior of the mould. A valve may be provided
on each of the spouts between the mouth and the mould, the said valves com-
municating with the exterior or other suitable overflow. The molten metal is
poured in at the mouth of one of the spouts, filling the mould and rising up the
other spout until it arrives at the valve, which being open allows of the overflow
of the metal. After pouring for a short time to allow of the fusing of the metal
composing the main article, against which the molten metal has come in contact,
the valve in the last mentioned spout is closed, and the opposite valve is opened.
The molten metal is now poured in at the mouth of the second spout and runs
through the mould and out at the opposite overflow valve, filling up any remaining
space in the mould and completing the fusion of the adjacent part of the main
article.
Instead of employing valves in connection with the spouts, suitable outlets may
be formed therein, and by tipping the mould on one side when pouring in the
molten metal, the superfluous metal will pass out at the outlet in the opposite
spout to that in which the metal is being poured, thereby simplifying the operation
of casting.
By the above described process, the new metal combines and mixes with the
metal forming the main article, and in solidifying the new or added auxiliary part
becomes homogeneously united therewith.
In order that our invention may be clearly understood and be more readily
carried into effect, we will proceed to describe same with reference to the
accompanying drawings in which similar letters refer to like parts in all the
figures.
Figs. 1 and 2 are respectively a sectional side elevation and a sectional end
view of a chill mould constructed for the purpose of casting a flange onto the end
of an existing tube.
Figs. 3, 4, 5 and 6 are respectively a front elevation, a sectional end elevation, a
plan, and a sectional front elevation of a mould constructed for the purpose of
casting an auxiliary part onto the bend of an existing tube.
Fig. 7 shows such a bend with the part added.

page_text: Referring particularly to Figs. 1 and 2 A is a framework having a bed B at its
upper surface, on which the slides C and D, are free to move backwards and
forwards. The framework A is mounted on swivel bearings A' which enable it to
be rocked on one side, in either direction. E is a plunger carrying a suitably shaped
core F for the reception of the tube H, onto the end of which tube the flange is to
be formed. G is a recess in the bed B of suitable shape and size to form the flange
required, and the ends of the slides C and D are of such a shape as to lap round
the base of the tube H, when they are iu the closed position. The faces of the
slides C and D are recessed in such a manner that when they are brought together,
the recesses form spouts J and K, passages J' and K' being also formed leading to
the recess G in the bed B. Overflow outlets L and M are formed in a like manner,
and communicate with the lower parts of the spouts J and K. N is a lever
arrangement for actuating the plunger E.
When it is required to form a flange on the tube H, the said tube H is slipped
over the boss F and the slides C and D are brought together. The framework A
is now tipped on one side, say to the right, thus bringing the spout K above the
level of the outlet L, and the molten metal is poured in at the funnel K. The
molten metal runs round the base of the tube H, fusing same and filling up the
recess G, and when it becomes full the molten metal rises up through the passage J'
and runs out at the overflow outlet L. The pouring is now stopped and the
frame A is tipped to the opposite angle, thus leaving the spout J above the level of
the outlet M. The molten metal is now run into the spout J, and the overflow takes
place at the outlet M. This second pouring effectually fills up any remaining
orifices which may be left in the mould, and ensures the complete fusion of the
lower part of the tube H, which latter in solidifying unites homogeneously with the
newly formed flange. The slides C and D are now moved apart, thus releasing
the tube H with the flange formed thereon, and by lifting the plunger E by means
of the lever N, the tube H with the flange thereon is raised, when it may be
withdrawn from the core F with facility.
Referring particularly to Figs. 3, 4, 5, 6 and 7, a pillar E is fastened to the
framework A, and a foot P is hinged to the upper part of the pillar E. R is a plug
which fits between the two slides C and D, and a screw socket S having a serrated
flange S is held on the plug R. Overflow outlets L and M are provided, as are
also spouts J and K; and passages J and K' are formed for the entry of
molten metal to the mould. The framework A may be mounted on swivels to
enable it to rock in a similar manner to that described with reference to
Figs. 1 and 2.
The apparatus is suitably inclined and ou pouring metal in at the spout J, it
runs into the mould through the passage J' until it fills the aperture G around the
screw socket S, and the molten metal then overflows through the outlet M. The
framework A is now tipped the reverse way, and metal is poured in at the spout K,
from whence it passes by way of the passage K to the aperture G, where it fills
any cavities which may be left in the mould and completes the fusion of the exposed
part of the existing tube, the foot P and the slides C and D preventing the fusion
of too much of the said tube. On the slides C and D being drawn apart, the tube
is withdrawn, the foot P turning on its hinge and allowing of the tube being
removed from the pillar E.
The plug F can now be unscrewed from the screw socket S which it leaves firmly
embedded in the new portion as seen at Fig. 7.
In some cases a single "pouring" may be found sufficient for fusing the adjacent
part of the main article and amalgamating same with the new metal, when one
inlet spout only is required.
Although we have particularly described our invention as applied to the
manufacture of flanges and sockets, yet it will be readily understood that by the
employment of apparatus constructed according to our invention, short tubes or other
auxiliary parts could be formed on existing articles.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that we
claim as our improvements in or connected with the casting and fusing of auxiliary
parts to articles formed of lead and other like metal is :-
1. The employment of a metal core and metal mould for holding the interior
and exterior of a tube or other hollow lead article, at the same time forming a mould
whereby a new auxiliary part may be formed on the existing article, substantially
as set forth.
2. The employment of two slides, which lap round a portion of the existing
article and form a mould substantially as and for the purpose set forth.
3. The combination of the frame A, bed B having recess G, slides C and D
having spouts J and K, passages J' and K', and outlets or valves L and M, sub-
stantially as set forth.
4. The particular arrangement and construction of the various parts for casting
a flange onto an existing tube, substantially as described and as shown at Figs. 1 and 2
of the accompanying drawings.
5. The pillar E carrying a hinged foot P, in combination with the slides C
and D, whereby the fusion of the existing article is confined, substantially as set
forth.
6. The combination of the framework A, bed B, slides C and D, pillar E,
plug F, spouts J and K, passages J and K', outlets L and M, foot P, and
socket S, substantially as set forth, and as shown at Figs. 3 to 6 of the accompanying
-drawings.
