PROVISIONAL SPECIFICATION left by the said Joseph Millington at the
Office of the Commissioners of Patents on the 22nd May 1883.
JOSEPH MILLINGTON, of Spring Vale Foundry near Wolverhampton in the
County of Stafford, iron-founder, "IMPROVEMENTS IN NEGRO-POTS, DUTCH
STOVES, CAMP OVENS, FRENCH OR MARMOT POTS, AND SIMILAR UTENSILS,"
f
Utensils of the class named in the title are usually formed with cast iron legs
in one piece with the body of the utensil. It is found that such legs are liable to
be broken off, and the chief object of this invention is to substitute for the cast
iron legs usually employed, wrought iron or steel legs permanently secured to the
body of the utensil so as to be practically in one piece therewith. This invention
has also the further object (in cases where such object is desirable) of casting upon
the wrought iron or steel legs, feet, similar to the feet which are now occasionally
formed upon the ordinary cast iron legs.
In carrying out this invention the legs are formed of tapered strips of sheet iron
or steel fullered or fluted into a curved shape in cross-section, or into an angular
or other shape as may be preferred for the special utensil to which the legs are to be
applied. One or more holes are punched or drilled through the larger end of each
leg very near to the extremity of such end, and, if feet are required on the legs, a
similar hole or holes are made also in the smaller end of the leg. These holes are
made preferably before the legs are fullered or fluted. The pattern of the body
part of the utensil has upon it bosses or snugs, each of such snugs having a recess
therein into which the larger end of a leg is inserted as the pattern is moulded up.
When the mould is ready for casting, the larger ends of the legs project within the
Dine 631

page_text: moulds of the snugs and as the metal is run into the mould it forms not only the
snugs around the upper ends of the legs but runs also into the hole or holes
through the metal of such legs forming cast iron pins or rivets therethrough, thus
holding the legs so firmly within the sockets that the legs may be bent without
loosening themselves within the sockets. . The plan of each of these snugs is
preferably made approximately to an enlarged contour of the section of the legs for
the sake of economy of material and neatness of appearance.
When it is desired to form feet upon the legs such feet are cast upon the legs
similarly as the sockets are cast therearound, the metal in this case also running
into the hole or holes through each leg with the effect of firmly holding the feet
thereon, and the plan of each of such feet is preferably of the same character as
that of the sockets, aforesaid, for the corresponding reasons.

MARMOT POTS AND SIMILAR UTENSILS
"
Utensils of the class named in the title are usually formed with cast iron legs in
one piece with the body of the utensil. It is found that such legs are liable to be
broken off, and the chief object of this invention is to substitute for the cast iron
legs usually employed wrought iron or steel legs permanently secured to the body
of the utensil so as to be practically in one piece therewith. This invention has
also the further object (in cases where such object is desirable) of casting upon the
wrought iron or steel legs feet similar to the feet which are now occasionally formed
upon the ordinary cast iron legs.
In carrying out this invention the legs are formed of tapered strips of sheet iron
or steel fullered or fluted into a curved shape in cross section or into an angular
or other shape as may be preferred for the special utensil to which the legs are
to be applied. One or more (but preferably three). holes are punched or drilled
through the larger end of each leg very near to the extremity of such end, and,
if feet are required, on the legs, a similar hole or holes are made also in the smaller
end of the leg. These holes are made preferably before the legs are fullered or
fluted. The pattern of the body part of the utensil has upon it bosses or snugs,
each of such snugs having a recess therein into which the larger end of a leg is
inserted as the pattern is moulded up. When the mould is ready for casting, the
larger ends of the legs project within those parts of the mould which are to form
the snugs and as the metal is run into the mould and forms the snugs around the
upper ends of the legs it runs also into the hole or holes through the metal of such
legs forming cast iron pins or rivets therethrough, thus holding the legs so firmly
within the sockets that the legs may be bent without loosening themselves within
the sockets. The plan of these snugs is preferably made approximately to an
enlarged contour of the section of the legs for the sake of economy of material and
neatness of appearance.
When it is desired to form feet upon the legs such feet are cast upon the legs
similarly as the sockets are cast therearound, the metal in this case also running
into the hole or holes through each leg with the effect of firmly holding the feet
thereon, and the plan of such feet is preferably of the same character as that of the
sockets aforesaid for the corresponding reasons.
Having thus stated the nature of the said invention I will now proceed more
particularly to describe and ascertain the manner of performing the same with
reference to the accompanying drawings, of which figure 1 is a vertical section
taken through the centre of a three legged or negro pot such section being taken
on the line of figure 2. Figure 2 is a view shewing the pot illustrated by
figure 1 to be turned up-side down so as to shew the bottom or under side thereof.
Figure 3 is an enlarged vertical section through one of the pot legs shewing its
connection with the pot, and also shewing the manner of fixing a cast iron foot
thereon, when such is required. The leg is shewn to be broken off in the middle
so as to avoid illustrating the entire length. Figure 4 is a plan of the connection
between the leg and pot illustrated by figure 3, looking at the under side thereof,
the leg being shewn in section as if cut off close to the connection as also is one

page_text: .
of the legs illustrated by figure 2. Figure 5 is a plan of the foot illustrated by
figure 3 the leg being shewn in section by this view as if cut off close to the foot.
Figure 6 is a view of the upper end of one of the legs before the same is fullered
or bent. The same letters of reference occurring upon any two or more of these
views indicate corresponding parts. A is the pot, B B B wrought iron legs thereto,
and C C C bosses or snugs upon the bottom of the pot and in which the upper
ends of the legs are held. The legs B B B are formed from sheet metal or other
thin metal and are fullered into a trough shape as shewn or into other convenient
shape, or they may be tubular, if desired, and such legs have one or more (but
preferably three) holes a & punched or otherwise formed through the metal of
their upper ends as shewn. These holes are preferably made before the sheet
metal is fullered or bent to the desired shape of the leg as shewn by figure 6.
In moulding up the pot, prints or patterns corresponding to the bosses or snugs
CCC are of course carried upon the bottom, and these prints or patterns have
openings through them corresponding in size and shape to the section of the metal
forming the upper ends of the legs, such openings being formed of course sufficiently
large to allow of the upper ends of the legs being readily inserted therein. The
legs are inserted with their upper ends within these openings so as to abut against
the pattern of the body or belly of the pot, and the moulding sand is rammed
around the projecting parts of such legs so that when the pattern is withdrawn
the legs are held within the sand of the mould and with their upper ends projecting
within the hollows formed by the patterns of the bosses or snugs; and as the
metal is run into the mould it forms not only the bosses or snugs C C C around
the upper ends of the legs B B B, but runs also into the hole or holes a &o through
the metal of such legs thus forming cast iron pins or rivets therethrough and
holding the legs firmly within the sockets. The bosses CCC are shewn to be
of the shape preferred, namely, to the contour, approximately, of the legs, and
are lightened out somewhat at the parts c cc for the sake of neatness of
appearance.
D (figures 3 and 5) shews a cast iron foot upon the bottom of the leg. When
such foot is desired, a hole or holes 6 &c are formed through the bottom of the
leg corresponding to the hole or holes a & through the upper end of the leg,
and the foot is moulded up and held upon the leg similarly as the boss C is
moulded up and the leg held therein by means of the cast metal rivets or pins
before described.
I have illustrated my invention only with reference to a three legged or negro
pot but its application to the other utensils named and referred to in the title will
now be sufficiently obvious without need for further illustration.
Having now stated the nature of my said invention and particularly described
and ascertained the manner of performing the same, I declare that what I claim.
as my invention and desire to secure by the hereinbefore in-part-recited Letters
Patent is
-
1st Fixing wrought iron or steel legs made from sheet or other thin metal into
cast iron bosses or snugs cast with and upon negro pots, Dutch stoves, camp ovens,
French or marmot pots and similar utensils, by forming holes through the metal
of such legs at the upper ends thereof and running the cast metal into such holes
when casting the pot or other utensil so as to form cast metal rivets or pins
through such legs, substantially as and for the purpose herein described and
illustrated by the accompanying drawings.
t
2nd Fixing cast metal feet upon wrought iron and steel legs made of sheet or
other thin metal and employed as the legs of negro pots, Dutch stoves, camp ovens,
French or marmot pots and similar utensils, by forming holes through the metal of
such legs at the lower ends thereof and running the cast metal into such holes
when casting the feet thereon so as to form cast metal rivets or pins through such
legs, substantially as and for the purpose herein described and illustrated by the
accompanying drawings.

page_text: 3d The combination of wrought iron or steel legs made from sheet or other
thin metal with the cast metal bodies of negro pots, Dutch stoves, camp ovens,
French or marmot pots and similar utensils, and also the combination with such
legs and bodies of cast metal feet, such legs and feet being fixed respectively in the
manner herein before described, all substantially as and for the purpose herein
described and shewn by the accompanying drawings
In witness whereof I the said Joseph Millington have hereunto set my
hand and seal this nineteenth day of November in the year of our
Lord One thousand eight hundred and eighty three.
