IMPROVEMENTS IN APPARATUS TO BE EMPLOYED IN THE MOULDING OF

PROVISIONAL SPECIFICATION left by the said Henry Sutcliffe and
Wright Sutcliffe at the Office of the Commissioners of Patents on the
27th April 1881.
HENRY. SUTCLIFFE and WRIGHT SUTCLIFFE, of the Firm of Messieurs Wright
Sutcliffe and Son, Sanitary Engineers and Brass Founders, of Adelaide St. Works,
Halifax, in the County of York. "IMPROVEMENTS IN APPARATUS TO BE EMPLOYED
IN THE MOULDING OF WATER CLOSET CISTERNS."
Hitherto water closet cisterns have been moulded in cast iron, which crack
from the effects; others have been made from sheet lead or other soft metal,
and soldered or burnt together. By our improved moulding apparatus we are
enabled to cast water closet cisterns from lead or other soft metal all in one piece ;
these we find better, more perfect, and less cost than as now made.
We employ a bed plate as block or core to form the inside of the cistern, of such
form as to allow facilities for heating the same by gas or fire, preferably gas, or a
mixture of gas and air. The shell or outer portion of the mould is formed so as to
leave the required thickness of metal for cistern, and may be hinged or have holes
left for removing same (by means of bars) after casting. The mould is held in
position by cotters and pins, studs, or other suitable means. The metal is poured
in at the top of the shell or outer portion of the mould, which is elevated so as to
ensure a good cistern casting of lead or other suitable metal. We can also cast in
the cistern at the same time valve sockets for the lever for regulating the flow.

"
Hitherto water closet cisterns have been moulded in cast iron, necessitating
separate moulding for each cystern; others, made from sheet lead or other soft
metal in parts, and the parts soldered or burnt together. By our improved
moulding apparatus we are enabled to cast any number of water closet cisterns
from lead or other soft metal by use of one mould and all in one piece; these we
find better, more perfect, and less cost than made as heretofore of lead parts
soldered, or of cast iron. We employ a bed plate supporting a block or core to
form the inside of the cistern; the outer portions of the mould are formed so as to
leave the required thickness of metal for the cistern, and may be hinged or have
holes left for removing same (by means of bars) after casting. The mould is held
in position by cotters and pins, studs, or other suitable means.
The metal is
poured in at the top of the shell or outer portion of the mould, which is elevated
so as to ensure a good cistern casting of lead or other suitable metal.
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 same may be fully
understood we have hereunto annexed 2 Sheets of Drawings illustrating the same,
in which the like numbers denotes the same part in the several views.
DESCRIPTION OF THE DRAWINGS.
is a plan
Fig. 1 is a side elevation of mould and stand on bed plate; Fig.
view of the same; Fig. 3 is an end elevation; Fig. 4 is a side elevation, having
the outer plate removed, and shewing cystern in section; Fig. 5 is an end view of
Fig. 4, outer plate detached; Fig. 6 is a cross section shewing both side plates
removed or clear of the cystern and core; Fig. 7 is a separate view of the central
part or portion of mould; Figs. 8 & 9 are views of the two outer plates;
Figs. 9 & 10 are plan and elevation of the core; Figs. 11 & 12 are plan and
clevation of two cysterns forming one double cystern.
At 1 is a bed plate or platform for the mould; 2 is the core, over which the
bridge shaped or central part of the mould 3 is placed, the lower portion thereof
resting on the outer parts of the core at 4. On the outer surface of the part 3 are
bosses 5 and 6, which by set screws 7 and 8 securely hold the studs or cotter
pins 9 and 10, on which the plates 11 and 12 forming the outer portions of the
mould are received; and when such are in position in relation to the centre part 3
(that is to say) in position for receipt of the metal (see Figs. 1, 2, 3,) these
plates 11 and 12 are securely held by the cotters 13, 14. The inner faces of the
plates 11 and 12 are planed or otherwise made perfectly true, and fit to the pro-
jecting facing pieces 15, 15, so as to make a close joint, and ensure the molten lead
poured in at the runners 17, 18, passing to the space between the core 2 and the
outer plates 11, 12, and central part 3 forming the cistern, as shewn at Fig. 6, and
by black line at Fig. 4. There the cistern is constructed having end flanges, as
at 19, and a side flange 20, the other side 21 having no flange, so that when two
cysterns are placed together the blank sides 21 are in the middle, and the
flanges 20, 20, at the outsides forming a double cistern (see Fig. 11). Where

page_text: single cisterns are to be made having flanges on all sides, the plate 11 will have
projecting side piece, leaving space for the additional flange 20, as in plate 12.
When the mould is in use the plates 11 and 12 are by the cotters 13, 14, secured in
position shewn at Figs. 1, 2, and 3, and the lead is poured in at the runners 17, 18.
On a sufficient quantity having been supplied the cotters 13, 14, are knocked out
and the side plates 11 and 12 are drawn by means of the handles 22, 22, aside
from the central part 3 and core 2 along the studs 9, 10, to the stop pins 23,
whereon the mould is by the hook 24, chain or rope 25, and weight 26 (which
partly counterbalances weight of mould), and by use of the handles 27, raised clear
of and above the core 2 for removal of the cast cistern; on block 2 at 16, 16, are
steady pins for ensuring the true position of the part 3 to the core 2. It will be
seen that the use of the stud pins 9, 10, and cotters 13, 14, by means of which the
parts of the mould are held together when the mould is in actual use, and by
means of which the parts of the mould may be instantly separated after casting,
greatly facilitate and expedite the casting, and reduce the labour required, and that
instead of the pins and cotters 13, 14, the studs 9, 10, may be chased or screwed,
and provided with wing or handle nuts. If the parts 11, 12, and 3 of the mould
are not separated as described the runners. 17, 18, must be loose and detachable
from the main parts of the mould, see Fig. 13, so that the runners 17, 18, when
lifted off and the "gate" or superfluous metal 28, 28, be cut away before the mould
can be lifted or removed from the core.
Having thus fully described the nature and particulars 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 understood that what we claim as
our Invention is, -
The improved apparatus for moulding, constructed and employed in manner
herein described and substantially as illustrated by Drawings annexed.
In witness whereof, I, the said Henry Sutcliffe, have, for and on behalf of
myself and the said Wright Sutcliffe, hereunto set my hand and seal, this
Twenty sixth day of October, in the year of our Lord One thousand eight
hundred and eighty one.
