IMPROVE- MEETS IN THE CASTING OR INCOTS
Year: 1867

page_text: LETTERS PATENT to Alexander Wilson, of the Cyclops Steel and Iron
Works, Sheffield, in the County of York, for the Invention of "IMPROVE-
MEETS IN THE CASTING OR INCOTS"
Sealed the 31st December 1867, and dated the 25th July 1867.
PROVISIONAL SPECIFICATION left by the said Alexander Wilson at
the Office of the Commissioners of Patents, with his Petition, on the
25th July 1867.
I, ALEXANDER WILSON, of the Cyclops Steel and Iron Works, Sheffield, in
the County of York, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN THE CASTING OF INGOTS," to be as follows:-
The object of this Invention is to cast ingots of steel or any other metals to
any given weight.
The Invention consists in placing the ingot mould upon the table of a
weighing machine, or upon a table supported by a steelyard or weighted
levers, or suspended from a spring balance; the ingot mould and everything
in connection with it is then weighed. By adding the weight of the ingot
to be cast to the weight of the ingot mould and its accessories I am enabled
to make the ingot of any given and desired weight; any other arrangement
for weighing the ingot mould and its contents may be employed if preferred,
and in addition a registering apparatus may be adapted thereto.

by the said Alexander Wilson in the Great Seal Patent Office on the
24th January 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALEXANDER
WILSON, of the Cyclops Steel and Iron Works, Sheffield, in the County of
York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fifth day of July, in the year of our Lord One
thousand eight hundred and sixty-seven, in the thirty-first year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Alexander Wilson, Her special licence that I, the said Alexander Wilson, my
executors, administrators, and assigns, or such others as I, the said Alexander
Wilson, my executors, administrators, and assigns, should at any time agree
with, and no others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN THE CASTING
OF INGOTS," upon the condition (amongst others) that I, the said Alexander
Wilson, my executors or administrators, by an instrument in writing under
my, or their, or one of their hands and seals, should particularly describe
and ascertain the nature of the said Invention, and in what manner the same
was to be performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date of the
said Letters Patent.
NOW KNOW YE, that I, the said Alexander Wilson, do hereby declare
the nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement, reference being had to the Drawing hereunto annexed, and to the
letters and figures marked thereon (that is to say) :-
The object of this Invention is to cast ingots of steel or any other metals to
any given weight.
The Invention consists in placing the ingot mould upon the table of a
weighing machine, or upon a table supported by a steelyard or weighted
levers, or suspended from a spring balance; the ingot mould and everything
in connection with it is then weighed. By adding the weight of the ingot to
be cast to the weight of the ingot mould and its accessories I am enabled to
make the ingot of any given and desired weight; any other arrangement for

page_text: weighing the ingot mould and its contents may be employed if preferred, and
in addition a registering apparatus may be adapted thereto.
In the accompanying Drawing I have shewn the simplest arrangement of
parts for effecting the object. of my Invention.
Fig. 1 is a sectional elevation of the weighing machine; Fig. 2 is a plan
view of the whole apparatus complete; and Fig. 3 is a plan view with the
weighing machine table and its supporting frame removed.
a is the ingot mould, and 6 the ladle whereby it is filled with the molten
steel or other metals of which the ingot is to be formed. It will be seen that
the mould a is placed on a table or platform c, which is in fact the platform
of a weighing machine such as is usually employed in railway stations for
weighing goods or passengers' luggage. In this instance the table c rests on
a frame d provided on its under side with a plunger d¹, which works in the
cylinder e whereby it is kept in a vertical position; the bottom of this plunger d¹
rests on a feather edge at the shorter end of a graduated leverf which rests
on another feather edge fulcrum g, and is provided with weights h, h', whereby
the weight of any body placed on the table c may be correctly ascertained. It
will be evident that by varying the position of the weights h along the gra-
duated lever f and adding weights on the end of the graduated lever at h¹
after having ascertained the weight of the mould any desired and lined
quantity of metal may be poured into the mould, and therefore ingots of\
desired weight may be produced with accuracy and facility.
.
I would here remark that in order to avoid unnecessary complication in
the Drawing I have shewn the simplest form of the common and well-known
steelyard principle of weighing. as adapted for the purposes of my Invention;
but it will be evident that if preferred the graduated lever f may be placed on
a level with the top of the ingot mould, and the weight of this latter trans-
ferred to the lever or steelyard f by means of suitable rods and levers, as is
well known.
In conclusion I would observe that although I have shewn in the accom-
panying Drawings and have described in detail an arrangement of weighing
apparatus which I have found to answer the purpose of my Invention,
I do not intend to claim as new the peculiar construction and arrangement of
parts shewn and described, nor do I intend to confine myself thereto, as other
constructions of weighing machines may be equally well applied for the pur-
poses of my Invention; but what I claim as new in the above-described
Invention of improvements in the casting of ingots is placing the ingot
mould on the table or platform of a weighing machine or otherwise adapting

page_text: it thereto so that the weight of the mould may be first ascertained, and then
pouring a regulated and determinate quantity of molten metal in so as to
obtain ingots of a given weight, as herein set forth.
In witness whereof, I, the said Alexander Wilson, have hereunto set
my hand and seal, the 20th day of January, in the year of our Lord
One thousand eight hundred and sixty-eight.
Witness,
WH. FIDDES,
