AN IMPROVEMENT IN MOULDING AND CASTING POTS
Year: 1884

page_text: PROVISIONAL SPECIFICATION.
I, GEORGE BINNIE of the Falkirk Iron Works, Falkirk in the county of
Stirling, Manager, do hereby declare the nature of my invention for "AN
IMPROVEMENT IN MOULDING AND CASTING POTS" to be as follows:-
In the Specification to Letters Patent granted to me on the 27th March 1871
N° 834, I described a mode of and apparatus for, moulding and casting pots, the
feet of pots so moulded being necessarily short, as the mould for each of those feet
was produced by forcing a pattern thereof, like a punch, into the rammed sand.
As there is a large demand for a pot with feet sufficiently long to admit of fire
under the pot, while its feet rest on the ground, the object of my present invention
is to provide means for casting pots with long feet in a manner similar to that
described in the Specification above referred to, with such modifications as are
necessary to suit the required lengthening of the feet. For this purpose, I mould
and cast the feet for each pot separately from the pot itself, and I place these feet,
three in number, in their proper positions in the mould box, fixing them in sockets
provided therein, and I ram the moulding, sand on them and on the pattern. After
the sand is ramined, I force through holes of the pot pattern, three print patterns,
each of which indents the sand in an annular form around the end of one of the
feet. The pattern is removed, the core is introduced and the metal is run into the
mould as described in my previous Specification, and a pot is thus produced having
three long feet, each of which has its end cast into a boss projecting from the
bottom of the pot, that boss being formed by the metal which runs into the annular
print above mentioned.

performed, to be particularly described and ascertained in and by the following
statement:
In the Specification to Letters Patent granted to me on the 27th March 1871
N° 834, I described a mode of and apparatus for moulding and casting pots, the
feet of pots so moulded being necessarily short, as the mould for each of those feet
was produced by forcing a pattern thereof like a punch into the rammed sand. As
there is a large demand for a pot with, feet sufficiently long to admit of fire under
the pot while its feet rest on the ground, the object of my present invention is to
provide means for casting pots with long feet in a manner similar to that described
in the Specification above referred to, with such modifications as are necessary to
suit the required lengthening of the feet. For this purpose I mould and cast. the
feet for each pot separately from the pot itself, and I place these feet, three in
number, in their proper positions in the mould box, fixing them in sockets provided
therein, and I ram the moulding sand on them and on the pattern pot. After the
sand is rammed I force through holes provided in the bottom of the pot pattern,
three print patterns, each of which indents the sand in an annular form around
the upper end of one of the feet. The pattern is removed, the core is introduced
and the metal is run into the mould as described in my previous Specification, and
a pot is thus produced having three long feet each of which has its end cast into
a boss projecting from the bottom of the pot, that boss being formed by the metal
which runs into the annular print above mentioned.
F
The accompanying drawings shew so much of the moulding and core boxes
employed in casting pots with long feet as will explain the method above described.
Fig. 1 is a section, fig. 2 is a plan and fig. 3 a side view of the half mould box K
with the half pattern A of a pot placed, for the purpose of ramming the sand
thereon, on the gate G which is shewn in fig. 4 with its recesses to form the
handles H.
*
The long feet F are separate castings one of which is shewn in fig. 5. These feet
are fixed as shewn in fig. 3 by cotters fin proper position in the half mould box K,
two of them being in the one half mould box as shewn in fig. 2 and one centrally
in the other half mould box. After the sand is rammed on the pattern A and
feet F, prints C are, by means of levers D,. forced out from. the pattern A into the
sand surrounding the ends of the feet F so as to impress round these ends, hollows,
which become filled with metal in casting and form bosses enclosing the insertions
of the feet F in the body of the pot. To prevent the feet from becoming loose or
turning, they are preferably made with small projections 88 at their extreme ends.
Fig. 7 is a front view and fig 8 an external plan of the half moulding box K.
Fig. 9 is a section and fig. 12 a plan of the core box M, which has a stationary
bottom M and two removeable half side pieces M³ that are held in place while the
core is being rammed by a ring N. Fig. 10 is a section, and fig. 11 a side view of
the complete mould box with the core L in position ready for casting the pot, the
metal being run in by the gate G.

page_text: 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 herein described method of casting pots with long feet, by fixing in the
mould box these feet, cast separately, and impressing in the sand around their ends
recesses to form bosses, securing them to the body of the pot.
Dated this 14th day of October 1884.
