IMPROVEMENTS IN ANVILS
Year: 1874

page_text: LETTERS PATENT to Joseph Evans, of Sheffield, in the County of
York, for the Invention of "IMPROVEMENTS IN ANVILS."
Scaled the 21st August 1874, and dated the 19th March 1874.
:
PROVISIONAL SPECIFICATION left by the said Joseph Evans at the
Office of the Commissioners of Patents, with his Petition, on the
19th March 1874.
I, JOSEPH EVANS, of Sheffield, in the County of York, do hereby
declare the nature of the said Invention for “IMPROVEMENTS IN ANVILS,"
to be as follows:-
Heretofore the steel surfaces of anvils have been welded or cast on to
a wrought or cast-iron anvil block. Now according to my Invention I
secure such steel surfaces to the body of the anvil by mechanical means.
I form a groove or grooves in the surface of the anvil block, the sides of
such grooves being so formed as to be nearer at one end than at the.
other, and also nearer at the top than at the bottom. Into the groove I
adjust and drive the steel which is to form the surface of the anvil.

page_text: After the steel surface has been driven into its place I insert screws or
wedges endwise into it and into the anvil block to hold the steel securely
in its place. The interior surfaces of the groove and the surfaces of the
steel which fit therein are filed or planed so as to fit accurately.
It will be understood that in anvils manufactured as above described
in accordance with my Invention the steel surfaces can be renewed from
time to time, and such surfaces can be formed of very even quality and
fine temper.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Joseph Evans in the Great Seal Patent Office on
the 1st September 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
EVANS, of Sheffield, in the County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Nineteenth day of March, in the
year of our Lord One thousand eight hundred and seventy-four, in the
thirty-seventh year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Joseph Evans, Her special
licensé that I, the said Joseph Evans, my executors, administrators, and
assigns, or such others as I, the said Joseph Evans, 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
tlierein 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 ANVILS," upon the condition (amongst others) that I, the said
Joseph Evans, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, should parti-
cularly 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:...

page_text: NOW KNOW YE, that I, the said Joseph Evans, 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-
:
,
Heretofore the steel surfaces of anvils have been welded or cast on
to a wrought or cast-iron anvil block. Now according to my Invention
.I secure such steel surfaces to the body of the anvil by mechanical
means. I form a groove or grooves in the surface of the anvil block, the
sides of such grooves being so formed as to be nearer at one end than at
the other, and also nearer at the top than at the bottom. Into the groove
I adjust and drive the steel which is to form the surface of the anvil.
After the steel surface has been driven into its place I insert screws or
wedges endwise into it and into the anvil block to hold the steel
securely in its place. The interior surfaces of tlie groove and the surfaces
of the steel which fit therein are formed, filed, or planed so as to fit
accurately.
It will be understood that in anvils manufactured as above described
in accordance with my Invention the steel surfaces can be renewed from
time to time, and such surfaces can be formed of very even'quality and
finc temper.
When making anvils according to my Invention the anvil block can
be formed either of cast iron, or steel, or of "Bessemer metal," or of
wrought iron.
The Drawings shew perspective views of various forms of anvils having
the steel faces A, A, secured to the anvil blocks B, B, according to my
Invention. After a steel surface A has been adjusted in the groove
formed in the anvil block B, I insert screws C or wedges D so as to hold
the steel surface A securely in its place.
According to my Invention I also employ wedges or keys E, E, with
grooved edges to assist in securing the steel surfaces A to the anvil
blocks B, or I secure the steel surface A to the anvil block B by the aid
of the wedges or keys E, E, only.
A person acquainted with the manufacture and use of anvils, aided by
the foregoing description and the Drawings, will readily understand
that the forms of the parts or grooves employed to secure the steel
surfaces A to the anvil blocks B, together with the manner of employing

page_text: the screws C, the wedges D, and the wedges or keys E, may be greatly
varied when adapting my Invention to various forms of anvils without
departing from the nature of my Invention.
What I claim is, securing the steel surfaces to anvil and forge hammer
blocks by mechanical means, substantially as herein-before described.
In witness whereof, I, the said Joseph Evans, have hereunto set my
hand and seal, this Twenty-ninth day of August, in the year of
our Lord One thousand eight hundred and seventy-four.
