COMPLETE SPECIFICATION.
An Improved Method of Casting Steel, and Apparatus therefor.
I, LEWIS WINFIELD MALLASEE, a citizen of the United States, residing at
the corner of Western and Sparta Streets West End Pittsburg in the County of
Allegheny and State of Pennsylvania United States of America Steel Smelter
do hereby declare the nature of my invention and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement:―
My invention relates to an improved apparatus for casting steel ingots, and
consists in providing the mold with a cap or continuation of the same whereby the
'pipe" or hollow portion formed in the ingot from the contraction of the metal
will be in a narrow and reduced end of the ingot, as will be fully described
hereinafter.
In the accompanying drawing
Fig. 1. is an end elevation of my improved ingot mold, for forming ingots in
accordance with my invention.
Fig. 2. is a transverse sectional view of the same.
Fig. 3. is a side elevation of the mold, one half being removed to show the
interior of the same.
Fig. 4. is a plan view of the mold.
To construct an ingot mold for forming ingots in accordance with my invention
I provide an oblong base plate 1 of a suitable size, on which the mold is placed.
This mold consists of two half sections 2. each of which is provided with integral
lugs 3. arranged near the top and bottom of the same, for the purpose of attaching
the two sections 2 together, by means of suitably formed clamps 4. The joint or
parting between these sections 2 consists of a groove 5 formed in one of the
sections, and a corresponding toungue 10. or projecting portion on the other, which
will prevent a direct opening through the sides of the mold, and thereby better
confine the metal therein. Placed on the top of this mold is a sectional cap 6. the
parts of which are held rigidly together by clamps 7, and the two sections joined
together in the same manner as the mold. This cap 6 is constructed with an
interior conical shaped chamber 9, and two circular openings 8. through which the
metal is poured into the mold.
This chamber 9 when filled with moulten metal will act as a sinker, or feeder, to
the metal in the mold 2. and when the ingot thus formed is cold, the "pipe" or
hollow in the ingot will be in the contracted or reduced top 9. which when the
ingot is hammered or rolled may be removed.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
A mold for casting ingots, consisting of the base portion constructed in two
sections, the meeting edges of which are provided the one with a groove and the
other with a toungue for engaging the groove, a sectional cap adapted to rest upon
the base portion, the meeting edges of which are provided the one with a toungue
and the other with a groove, and having an interior conical shaped cavity provided

for engaging the said lugs, substantially as described.
