Year: 1855

page_text: LETTERS PATENT to Edward Cooke, of Balsall Heath, near Birmingham,
in the County of Warwick, Accountant Clerk, for the Invention of "AN
IMPROVEMENT OR IMPROVEMENTS IN MOULDS USED IN CASTING CERTAIN PARTS
OF METALLIC FURNITURE."
Scaled the 25th January 1856, and dated the 9th August 1855.
PROVISIONAL SPECIFICATION left by the said Edward Cooke at the
Office of the Commissioners of Patents, with his Petition, on the 9th
August 1855.
I, EDWARD COOKE, of Balsall Heath, near Birmingham, in the County of
Warwick, Accountant Clerk, do hereby declare the nature of the said Inven-
tion for "AN IMPROVEMENT OR IMPROVEMENTS IN MOULDS USED IN CASTING CERTAIN
PARTS OF METALLIC FURNITURE" to be as follows:-
My Invention relates to the stocks or moulds which are used in casting the
corner blocks and other cast pieces of metallic bedsteads and other articles of
metallic furniture, the said stocks or moulds consisting of two dies connected
by a hinge joint, and made when used to embrace the pillar or rod on which
the block or other piece is to be cast. The melted metal being poured into the
stock or mould is cast upon the pillar or rod. The said stocks or moulds are
commonly made by the ordinary process of casting in sand, and require to be
finished by filing and other manual processes.

page_text: My Invention consists in making the said stocks or moulds by casting the
same in metal moulds, whereby the fitting required when the said stocks or
moulds are made by the ordinary method is unnecessary, the said stocks being
sufficiently true for use without the usual fitting. Great economy in the produc-
tion of the castings of metallic furniture is effected by the use of my Invention.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Edward Cooke in the Great Seal Patent Office on the
7th February 1856.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
COOKE, of Balsall Heath, near Birmingham, in the County of Warwick,
Accountant Clerk, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Ninth day of August, in the year of our Lord
One thousand eight hundred and fifty-five, in the nineteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Edward Cooke, Her special licence that I; the said Edward Cooke, my
executors, administrators, and assigns, or such others as I, the said Edward
Cooke, 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 "AN IMPROVEMENT OR IM-
PROVEMENTS IN MOULDS USED IN CASTING CERTAIN PARTS OF METALLIC FURNITURE,
upon the condition (amongst others) that I, the said Edward Cooke, my execu-
tors 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 Edward Cooke, do hereby declare the
nature of the 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 thereof, that is to say :-
My Invention relates to the moulds or stocks which are used in casting the
corner blocks and other cast pieces of metallic bedsteads and other articles of
metallic furniture, such as chairs, sofas, and couches. The said moulds or

page_text: stocks consist of two or other number of dies connected together by hinges or
otherwise, which said moulds or stocks are when used made to embrace the
pillar or rod or part on which the block or other pièce is to be cast. The
melted metal being poured into the stock or mould is cast upon the said pillar
rod or part. The said stocks or moulds are commonly made by the ordinary.
process of casting in sand, and require to be finished by filing and other
manual processes.
:
My Invention consists in making the said stocks or moulds by casting the
same in metal moulds, whereby the finishing required when the said stocks or
moulds are cast in sand is unnecessary, the said stocks or moulds being suffi-
ciently true for use without the usual finishing and fitting.
.
In order that Invention
my
may
the better be understood, I have illustrated
in the accompanying Drawing the method of making a pair of stocks or moulds
according to my said. Invention.
.
Figure 1 represents an ornament cast upon two crossing rods, such as are
used in the head and foot rails of metallic bedsteads, and in. other parts of
metallic furniture. The method of casting the same is illustrated in Figures
2, 3, and 4; a pair of stocks or moulds, one of which is represented in Figure 2;
is made to embrace the rods upon which the ornament is to. be cast, as shown
in Figure 3. Figure 4 is a' section, taken in a horizontal plane through the
line a of Figure 3. Melted metal is poured in at the "get",b, and the air
escapes at the passage c; the said melted metal fills the cavity d, d, and forms
the ornament represented upon the crossing rods, Figure 1. In making the
stocks or moulds, Figures 2, 3, and 4, I form a die or mould, shown in eleva-
tion in Figure 5, in end view at e, Figure 6, and in section at f, Figure 7, the
said section, Figure 7, being taken through the line x, Figure 5; the said die
or moulde has an internal figure corresponding to the external figure of one
of the stocks or moulds, Figures 2, 3, and 4. I take a model g, Figure 7, of
the ornament which I wish to cast upon the crossing rods, Figure 1, the said
model being made of a material not injuriously affected by the heat to which
it has to be exposed; I fix. the said model 9 upon a plate h, Figures 6
and 7, and lay the said plate against the face of the mould, Figure 5, as will
be understood by an inspection of Figures 6 and 7 ; I then place a plate l,
Figures 6 and 7, against the plate k; the three parts, the mould e and
plates. k, l, are bound firmly together by screws or otherwise. Fused cast iron
is poured down the channel m, and passing through a channel in the
bottom of the plate k, indicated by dotted lines at n, Figure 7, the said
fused cast iron arrives at o, see Figure 5, and. rising up fills the interior of
the mould, the air escaping by the passages p, q. On taking to pieces the
..

page_text: mould, Figures 6 and 7, the casting occupying the interior of the same
constitutes the stock or mould, Figure 2.
The parts represented in Figures 5, 6, and 7, may be employed to cast
a great number of the stocks or dies, Figure 2, and by casting the said
stocks or dies, Figure 2, in metal moulds, instead of in the ordinary sand
moulds, great economy in the production of the said stocks is effected. By
changing the ornament g, Figure 7, the same moulds may be employed for
casting stocks having different ornaments.
Although I have only described and illustrated my Invention as applied to
the making of stocks or moulds to be used for casting ornaments upon crossing
rods, as represented in Figure 1, yet my Invention is applicable to the pro-
duction of stocks or moulds for casting corner blocks, and for the production
of stocks or moulds for casting all those parts of metallic furniture to the
casting of which stocks or moulds are or may be applicable. As I believe
my Invention will be fully understood by the description herein given, reference
being had to the accompanying Drawing, I do not think it necessary to describe
and represent the other. stocks or moulds to the manufacture of which my
Invention is applicable.
Having now described the nature of my Invention, and the manner of
carrying the same into effect, I wish it to be understood that I do not limit
myself to the precise details herein described, as the same may be varied
without departing from the nature of my said Invention; but I claim as my
Invention, the improvement or improvements in moulds or stocks used for
casting those parts of metallic furniture which are cast upon the rods, pillars,
rails, or parts of the said furniture, as herein described, and illustrated in the
accompanying Drawing, the said improvement or improvements in the said
moulds or stocks consisting in making them by casting them in metal moulds
upon a model of the ornament or part which is to be afterwards cast in them.
In witness whereof, I, the said Edward Cooke, have hereunto set my
hand and seal, this Sixth day of February, in the year of our Lord
One thousand eight hundred and fifty-six.
