Forge, Sheffield, in the County of York, for the Invention of "IMPROVEMENTS
IN THE MANUFACTURE OF ANVILS."
aled the 24th April 1877, and dated the 4th November 1876.
PROVISIONAL SPECIFICATION left by the said James Brooks and William
Cooper at the Office of the Commissioners of Patents on the 4th November 1876.
JAMES BROOKS and WILLIAM COOPER, both of Mousehole Forge, Sheffield, in the
County of York. "IMPROVEMENTS IN THE MANUFACTURE OF ANVILS."
Our Invention relates to the manufacture of wrought-iron anvils with steel
faces.
In carrying out our Invention we mould the bottom part and the upper part of the
anvil in wrought iron by means of hydraulic or steam pressure, and we afterwards
join them together, and attach the steel by the same means. We thus complete an
anvil with three pieces of material, and in some cases with two only, whereby a
perfectly solid wrought-iron and shear-steel anvil is produced.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said James Brooks and William Cooper in the Great Seal Patent Office
on the 30th April 1877.
JAMES BROOKS and WILLIAM COOPER, both of Mousehole Forge, Sheffield, in the
County of York. "IMPROVEMENTS IN THE MANUFACTURE OF ANVILS."
This Invention has for its object the effecting a considerable and very important
economy, both in the labour and cost of production, hitherto unavoidable in the
manufacture of wrought-iron anvils with steel faces.
Heretofore it has been customary to manufacture such anvils in a great number
of separate parts, as many as thirteen being frequently employed for this purpose.
Each of such separate parts has necessarily to be subsequently forged and welded
together, thereby greatly increasing the labour, time, and cost of production.

page_text: Now in carrying out our Invention we obviate these disadvantages in the
following manner:-We take a bloom of wrought iron whilst it is in a welding
state, and force it into a suitable mould while in such heated and softened state
either by steam or hydraulic pressure. The internal configuration of such mould
corresponds to the shape of the lower part or base of the anvil required to be
manufactured, and the metal when so forced in thus assumes the desired shape.
We then form and shape the upper portion of the body of the anvil from a second
bloom of wrought iron in a similar manner to that before described, and we then
weld them together in the middle by steam or hydraulic pressure, after which we
attach the steel face plate (which we prefer to manufacture of the best double shear
steel) to the body of the anvil by similar hydraulic or steam pressure, and so com-
plete the manufacture thereof.
It will be obvious from the foregoing description of our improved system of
manufacturing anvils that an immense economy both in the cost, time, and labour
of production is the result, while it also secures a perfectly solid wrought-iron and steel
anvil, the body, feet, and pike whereof are in one solid piece, and cannot therefore
come to pieces through bad workmanship, thus possessing a considerable advantage
over those hitherto in use.
Having now particularly described and ascertained the nature of our said
Invention, and the manner of carrying the same into effect, we would have it
understood that we claim, the improved method of manufacturing anvils, substan-
tially in the manner herein-before set forth and described.
In witness whereof, I, the said James Brooks and William Cooper, have
hereunto set our hands and seals, this Twenty-eighth day of April, in the
year of our Lord One thousand eight hundred and seventy-seven.
