Year: 1856

page_text: LETTERS PATENT to Samuel Lilley, of Birmingham, in the County of
Warwick, Engineer and Machinist, for the Invention of "IMPROVEMENTS
IN THE MANUFACTURE OF SHIPS' IRON WORK, A PART OF WHICH IMPROVE-
MENTS IS APPLICABLE TO THE MANUFACTURE OF OTHER ARTICLES IN IRON."
Sealed the 13th February 1857, and dated the 16th August 1856.
PROVISIONAL SPECIFICATION left by the said Samuel Lilley at the
Office of the Commissioners of Patents, with his Petition, on the
16th August 1856.
I, SAMUEL LILLEY, of Birmingham, in the County of Warwick, Engineer
and Machinist, do hereby declare the nature of the Invention for "IMPROVE-
MENTS IN THE MANUFACTURE OF SHIPS' IRON WORK, A PART OF WHICH IMPROVE-
MENTS IS APPLICABLE TO THE MANUFACTURE OF OTHER ARTICLES IN IRON," to be as
follows:-
:
My said Invention consists in the manufacture of slides, blocks, and other
castings for ships by the use of chilled moulds, that is to say, metal moulds in
place of the ordinary sand moulds. I make the said ships' castings either
of ordinary cast iron, or of that kind of cast iron which may be softened or
annealed, and which is commonly called malleable iron.
That part of my Invention which relates to the casting of ships' iron work
of ordinary cast iron in metal moulds is also applicable to the casting of door

page_text: knockers, cannons; knobs, and roses for doors, hooks, sash rollers and weights,
pullies, door porters, castors, hat and coat pins, hinges, coffin and other
handles, fenders, grates, ovens, stoves, safes, mangers, and pig troughs, window
frames, grating, tea-pot handles, sash racks and worms, saucepans, sad irons,
Italian irons, box irons, spittoons, presses for copying letters, and ornaments
for gas fittings.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Samuel Lilley in the Great Seal Patent Office on the
14th February 1857.
--
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
LILLEY, of Birmingham, in the County of Warwick, Engineer and Machinist,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixteenth day of August, in the year of our Lord
One thousand eight hundred and fifty-six, in the twentieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Samuel Lilley, Her special licence that I, the said Samuel Lilley,
my executors, administrators, and assigns, or such others as I, the said
Samuel Lilley, 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 MANUFACTURE OF SHIPS' IRON WORK, A PART OF WHICH IMPROVEMENTS IS
APPLICABLE TO THE MANUFACTURE OF OTHER ARTICLES IN IRON," upon the condition
(amongst others) that I, the said Samuel Lilley, my executors or adminis-
trators, 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 Samuel Lilley, do hereby declare
the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the. following
statement thereof, that is to say :-
My said Invention consists in the manufacture of slides, blocks, and other
castings for ships by the use of chilled moulds, that is to say, metal moulds in

page_text: place of the ordinary sand moulds. I make the said ships' castings either of
ordinary cast iron or of that kind of cast iron which may be softened or
annealed.
That part of my Invention which relates to the casting of ships' iron work of
ordinary cast iron in metal moulds is also applicable to the casting of door
knockers, cannons, pullies, fenders, grates, ovens, stoves, safes, mangers and
troughs, window frames, gratings, saucepans, sad irons, Italian irons, box
irons, spittoons, presses for copying letters, and ornaments for gas fittings.
In carrying my Invention into effect, I make suitably formed moulds of cast
iron, the said moulds being provided where necessary with metallic cores
passing into or through them. The parts of which the said moulds are made
are joined together when the said moulds are being used by methods commonly
resorted to in other casting processes, and which I do not think it necessary
to describe. The interiors of the moulds are made accurate in form and
smooth.
By the use of the said metal moulds the castings made therein have a
greater hardness on their surface than articles made in sand moulds, and the
manufacture of the said articles is more economical than the ordinary manu-
facture, and a great number of the same articles can be made in a mould
without injuring it.
Having now described the nature of my said 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 improvements in the manufacture of
ships' iron work, and the other articles herein-before described, that is to say,
manufacturing ships' iron work of ordinary cast iron, or cast iron that can be
annealed in chilled moulds, and the casting of the other articles herein-before
enumerated of ordinary cast iron cast in chilled moulds.
In witness whereof, I, the said Samuel Lilley, have hereunto set my
hand and seal, this Eleventh day of February, in the year of our
Lord One thousand eight hundred and fifty-seven.
Witness,
GEORGE SHAW.
SAMUEL LILLEY. (L.s.)
