IMPROVED MEANS FOR CASTING OR FORMING PROJECTIONS WITH AND UPON CULINARY UTENSILS AND OTHER CASTINGS
Year: 1885

page_text: We, RICHARD CLAYTON, Chairman of the Cannon Hollowware Company Limited,
Deepfields, near Bilston in the County of Stafford, hollowware manufacturers, and
JOSEPH MASON, of Castle View Terrace, Roseville, Coseley, near Bilston, aforesaid,
foreman moulder, do hereby declare the nature of our invention for IMPROVED
MEANS FOR CASTING OR FORMING PROJECTIONS WITH AND UPON CULINARY UTENSILS
AND OTHER CASTINGS and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement reference
being had to the accompanying drawings and the letters of reference marked
thereon:-
Bail-handle ears and other ears and handles and other projections upon cast
metal holloware utensils and other castings are at present moulded for casting by
means of corresponding patterns upon or dowelled to the block or pattern employed
for the body of the utensil or the portion of the casting from which such projections
are to stand out; and these projections are not only somewhat difficult to mould
owing to their slightness (frequently) compared with the other parts of the pattern,
and their having in certain cases to be drawn out separately from the mould, but,
in the case of ears and analogous parts which have openings through them or
between themselves and the body of the utensil or other casting, the portions of
sand forming the cores for such openings are slight in volume and liable to give
way more or less during the casting of the molten metal. In certain cases also it
is necessary to form dry-sand moulds made in suitable core-boxes for the purpose
of casting such projections.
Now the object of this invention is to avoid the use of patterns, and also the use
of dry-sand moulds, for the projections above referred to; and this invention
consists in the employment of chills to form the moulds for such projections and
the use of such chills in combination with the ordinary or any convenient patterns
for the bodies of the utensils or the portions of the castings from which the
projections are to stand out.
We will first describe. our invention with special reference to the formation of
a bail-handle ear for a culinary utensil, when its application generally for the
formation of the projections above referred to will be readily understood without
nood for further description

page_text: Figure 1, of the accompanying drawings, is a vertical section through the upper
part of one side of the pattern of a negro-pot or other culinary utensil, and shews
the interior of one half of a chill forming the mould for one of the ears for the
bail-handle. Figure 2 is an interior view of the opposite half of the chill. Figure 3
is a plan of the chill as put together to form the mould for the ear; and figure 4 is
a view of the chill looking in the direction of the arrow a (figure 1) The same
letters of reference occurring upon two or more of these views indicate corre-
sponding parts. A is one half of the chill and B the other half. The two halves
are divided from one another, as shewn, and when put together face to face are
guided into their proper relative positions and prevented from slipping out of
such positions by means of projections b b upon the one half chill fitting into
recesses cc in the other half chill, or by other convenient means. The interior of
the chill is hollowed out so that when the halves are put together and butted
against the body pattern such hollow corresponds to the interior shape and
dimensions of the intended ear. de are two half cores, one being formed as a
solid piece within one half chill and the other as a corresponding piece in the other
half chill, and so that they butt together when the chill is put together and form
between them the core for the intended hole through the ear.
In moulding up the body of the utensil the chills to form the ears are placed in
position against the pattern and the moulding sand is rammed around them; and
when the body pattern is withdrawn from the sand the chills of course remain in
position within the moulding sand. When the casting is taken out of the mould
the chills drop away or are readily removed from the cars.
Figure 1 is not intended to shew that the part of the pattern to form the upper
part of the utensil is to be moulded in the position shewn, as such part may of
course be downwards or in any convenient position in the mould.
Chills employed for other projections with and upon castings are constructed and
employed similarly as the chills already described, with such modifications as will
be apparent to suit the special purpose for which they are required.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is
1. Casting or forming projections with and upon culinary utensils and other
castings by means of chills employed in combination with the ordinary or other
convenient patterns employed to form the moulds for the bodies of the utensils or
portions of the castings from which the projections are to stand out, substantially
as herein described and shewn by the drawings.
2. Casting or forming projections with and upon culinary utensils and other
castings by the means or aid of chills formed in halves or otherwise divided, such
chills being employed in combination with the ordinary or other convenient
patterns employed to form the moulds for the bodies of the utensils or portions
of the castings from which the projections are to stand out, substantially as
herein described and shewn by the drawings.
3. The chill herein described and illustrated by the figures on the accompanying
drawings, substantially as and for the purpose herein described.
