IMPROVEMENTS IN THE MANUFACTURE OF ANVILS
Year: 1858

page_text: LETTERS PATENT to Peter Wright, of Dudley, in the County of Worcester,
Manufacturer, for the Invention of "IMPROVEMENTS IN THE MANUFACTURE
OF ANVILS."
PROVISIONAL SPECIFICATION left by the said Peter Wright at the
Office of the Commissioners of Patents, with his Petition, on the 29th
October 1858.
I, PETER WRIGHT, of Dudley, in the County of Worcester, Manufacturer, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN THE
MANUFACTURE OF ANVILS," to be as follows:-
The object of my Invention is to unite the two halves of an anvil without
welding them together, as in the process described in the Specification of a
Patent granted to me, bearing date the Twentieth day of January, in the year
of our Lord One thousand eight hundred and fifty-two. The way in which I
proceed to accomplish this is by first making the top part of the anvil in one
solid piece, and then by casting or stamping the bottom part to correspond.
I then proceed to join the two parts together, by first clearing, by a planing
machine or otherwise, the slot or groove, which has been previously been
roughed out of the top part while in the process of forging or rolling, and then
uniting by a dovetail kind of joint the two parts together; my object being to
economise labour and materials in the manufacture of anvils by uniting a cast
metal or malleable iron bottom to a wrought iron top, steeled and finished in
the usual manner.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, PETER
WRIGHT, of Dudley, in the County of Worcester, Manufacturer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-ninth day of October, in the year of our Lord
One thousand eight hundred and fifty-eight, in the twenty-second year of
Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said Peter Wright, Her special licence that I, the said Peter
Wright, my executors, 'administrators, and assigns, or such others as I, 'the'
said Peter Wright, 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 ANVILS," upon the condition (amongst others) that I, the said
Peter Wright, 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 Peter Wright, 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, to be as follows:-
My Invention consists of the improvements hereinafter particularly
described and illustrated in the accompanying Drawing in manufacturing
anvils. In the Specification of a Patent granted to me, bearing date the
Twentieth day of January, in the year of our Lord One thousand eight hundred
and fifty-two, I have described, among other methods, the manufacture of
anvils by making each anvil in two halves, which halves are joined together by
the process of welding. The object of the Invention herein described is to
unite the said 'halves without resorting to the process of welding.
According to one method of carrying my Invention into effect, I make the
top part or half of the anvil in one solid piece, as described in the Specification

page_text: of my Patent dated the Twentieth day of January, in the year of our Lord One
thousand eight hundred and fifty-two, and I make the bottom part or half by
casting or stamping the said top and bottom halves of the anvil, being afterwards
connected by a dovetail sort of joint. The upper part or half of the anvil has
in its under side a dovetail groove, and the lower half of the anvil has on its
upper side a dovetail which slides in the groove in the upper part. The dove-
tail groove is roughly formed in the upper half or part during the process of
making the said part by forging or rolling, and is afterwards cleared out by a
planing machine or otherwise. The dovetail on the lower half is formed
during the making of the said lower half by casting or stamping.
Figure 1 of the Drawing represents in side elevation the two parts of an
anvil separately constructed according to this part of my Invention, and
Figure 2 represents an end elevation of the same. Figures 3 and 4 represent
in longitudinal section and end elevation respectively the said parts joined
together. The same letters indicate the same parts in the several Figures.
a is the upper part of the anvil made of one solid piece, the said part a
having on its under side the dovetail groove or slot b; c'is the lower or bottom
part of the anvil, having on its summit a dovetail d. After the said parts a
and c have been joined together by the insertion of the dovetail d into the
groove b, as represented in Figures 3 and 4, I pass a pin or cotter e through
the joint, as shown in Figure 3, and thereby firmly fix the said parts in their
respective places.
Another method of carrying my Invention into effect consists in forming the
top half or part of the anvil with a dovetail shank, or a slank so shaped that
the lower end is larger than the upper end. The said top half is then placed
in a die or block made to fit the under part of the said top half to give a solid
bearing while in the process of steeling, which is performed by a steam or
other suitable hammer. I afterwards place the said top half or part in a
mould or in sand, and cast upon the said dovetail shank the bottom half or
part of the anvil. The two halves or parts of the anvil are thus firmly con-
nected together, and a complete and solid anvil produced. I make the
bottom part of the anvil of cast iron or malleable iron, or other suitable
metal.
Figures 5 and 6 represent in side elevation and end elevation respectively
the two parts of the anvil separately made according to this part of my
Invention; and Figures 7 and 8. represent in longitudinal and transverse
sections the said parts connected together, the lower half or part of the anvil.
having been cast upon the shank of the upper part; f is the upper part of the
anvil carrying a dovetail shank g; h is the lower part of the anvil cast upon

page_text: the said shank g, as represented in Figures 7' and 8. By casting the part h
upon..the shank g a complete and solid anvil is formed.
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 Invention; but I claim as my
Invention,
Firstly, the improvement herein-before described and illustrated in Figures
1, 2, 3, and 4 of the accompanying Drawing in manufacturing anvils, that is
to say, manufacturing anvils by connecting the two halves of the anvil together
by means of a dovetail sort of joint.
Secondly, the improvement herein-before described and illustrated in
Figures 5, 6, 7, and 8 of the accompanying Drawing in manufacturing anvils,
that is to say, forming upon the under side of the top part or half of the anvil
a dovetail shank, or a shank so shaped that the lower end is larger than the
upper end, upon which said shank the lower part or half of the anvil is cast,
and a solid anvil thereby produced.
In witness whereof, I, the said Peter Wright, have hereunto set my
hand and seal, this Seventh day of April, in the year of our Lord One
thousand eight hundred and fifty-nine.
Witness,
GEORGE SHAW.
PETER WRIGHT. (L.S.)
