Complete Specification Accepted, 9th Nov., 18
I, WILLIAM ROBINSON, of 32, Milton Street, Middlesborough-on-Tees, in the county
of York, Engineer, do hereby declare the nature of this invention to be as follows:-
My invention has reference to a construction of ingot moulds made in sections
connected by dove-tailed keys, each section being made at its inner part with a lip to
overlap a portion of the inner surface of the adjoining section so as to make a good
joint and give the required rounded form to the corner of the ingot. The dove-tailed
keys are of slightly tapering form in the direction of their length, as also are the
corresponding grooves formed in the abutting edges of the sections of the mould wall,
the arrangement being such that by more or less withdrawing the gear keys, allowance
will be made for expansion: or if the keys be driven further in, the walls of the mould
will be moved inward as may be desired in the event of contraction of the ingot.
The sections are provided with the necessary lugs and dies, and the portions forming
the side walls of the mould are removable from the bottom thereof through which the
dove-tailed keys extend. In some cases the ingot moulds may be provided with
liner plates.

page_text: I, WILLIAM ROBINSON, of 32 Milton Street, Middlesborough-on-Tees, in the County
of York, Engineer do hereby declare the nature of this 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 has reference to a construction of ingot moulds made in sections
connected by dove-tailed keys, each section being made at its inner part with a lip to
overlap a portion of the inner surface of the adjoining section so as to make a good
joint and give the required rounded form to the corner of the ingot. The dove-tailed
keys are of slightly tapering form in the direction of their length, as also are the
corresponding grooves formed in the abutting edges of the sections of the mould wall,
the arrangement being such that by more or less withdrawing the gear keys, allowance
will be made for expansion or if the keys be driven further in, the walls of the
mould will be moved inwards as may be desired in the event of contraction of the
ingot. The sections are provided with the necessary lugs and bolts, and the portions
forming the side walls of the mould are separable from the bottom thereof, through
which the dove-tailed keys extend. Referring to the accompanying sheet of
drawings
Fig. 1 is an isometric view of an ingot mould according to this invention, and
Fig. 2 is a cross section. The walls of the mould are formed in two parts or
sections A and B each comprising two sides, or an end and a side. The mould is
completed by a base or bottom Cupon which the walls stand. Lugs D, E are formed
on the sections A and B to enable them to be bolted together, if required, while each
section is also furnished with dove-tailed key ways F F running lengthwise.
These key ways are of gradually increasing depth from end to end, and oach pair
is provided with a double dove-tailed key, so proportioned that as it is driven forward
it draws the two parts A and B nearer to each other closing the mould upon the
ingot within it.
GG are strips for closing the joint, and preventing the entry of
sand, and H H ribs for fixing the position of the walls with respect to the base. There
are holes in the base through which the keys can pass.
Having now particularly described and ascertained the nature of the said invention,
and in what manner the same is to be performed I declare that what I claim is :-
1. An ingot mould made in sections connected by keys, the arrangement being such
that by driving the keys the sections may be brought nearer together or placed
further apart, substantially as described.
2. The improved ingot mould constructed and arranged substantially as described
with reference to the drawings.
