Complete Accepted, 9th Aug., 1887.
JAMES HAVENHAND Manufacturer 116 Victoria Road, Heeley Sheffield do hereby
declare the nature of this invention to be as follows:-
An Ingot mould, with dove-tailed recesses cast in, on the inside of one or both
halves of the mould and triangular holes through the sides to receive a triangular
projection or projections which are interchangable, so that when one angle becomes
worn or otherwise defective, another angle may be turned, and so on until all the
angles are worn or otherwise defective and new ones required in their place or places.

Improvements in Ingot Moulds.
I, JAMES HAVENHAND Manufacturer, 116 Victoria Road, Heeley Sheffield do
hereby declare the nature of this invention and in what manner the same is to be
5 performed, to be particularly described and ascertained in and by the following
statement :-
My invention of improvements in Ingot Moulds, refers more particularly to such
ingot moulds as are constructed to nick or indent the ingots cast in them for the

page_text: purpose of facilitating the process of "topping" or breaking off the defective or piped
end of the ingot.
The annexed sheet of drawings illustrates my improvements and how the invention
is carried into practice, similar letters of reference indicating similar parts in any of
the figures in which they occur.
Fig. 1, is an elevation of one half of a mould, showing the interior.
Fig. 2, side view of complete mould.
Fig. 3, enlarged sectional detail, cut through xx showing the triangular projection,
or edge of steel bar.
Fig. 4, represents an ingot indented at each side, as it leaves the ingot mould.
I am aware that Ingot moulds are made having projecting strips cast upon them
for the purpose of forming indentations in the ingots, such strips being cast of the
same metal as the ingot mould, and solid with the mould, and I therefore wish it to be
understood that I do not lay any claim to such method, my invention being to
supersede such a defective and imperfect system.
My invention consists in constructing Ingot moulds with projections or nicking
strips of more durable material than the cast metal of which the ingot mould is made,
and so that they can be turned round when one edge is worn, and also be replaced by
a new strip when completely worn out, thus prolonging the life of the mould.
In carrying out my invention as applied to an ordinary rectangular ingot mould as
shown in Figs. 1 & 2, for example, made in two parts or halves, I make in the face
of the ingot mould A, an undercut or dovetailed slot B, extending from side to side
and terminating in triangular holes made through the sides C, C, and in which I
place a length of triangular steel D so that one of its edges E, will project from the
openside of the slot into the body of the mould, as shown clearly in Fig. 3. A
similar steel nieking strip may be fitted to each part of the mould, or to one side
only.
A simple method of carrying out the above described arrangement, is to place the
triangular strip of steel in the desired position in the sand, when making the Ingot
mould and cast the molten metal upon it as by this means fitting is avoided.
When the projecting angle E of the strip becomes worn and defective by the action
of the molten steel, it may be driven out of the slot, and one of the perfect angles
be brought into use; when the strip is worn out it can be replace with a new one.-
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 :-
1. An Ingot mould having one or more removable nicking strips for the purpose
specified, and substantially as hereinbefore described and illustrated.
:-
2. The combination with an Ingot mould, of one or more triangular strips of steel
(or of other antifusible metal) fitting in grooves, for the purpose specified and
substantially as described and shown.
