page_text: LETTERS PATENT to Charles Davage, of Sheffield, in the County of
York, Steel Forgeman, for the Invention of "IMPROVEMENTS IN
MACHINERY FOR FORMING OR SHAPING AXLES AND OTHER ARTICLES IN STEEL
OR IRON.'
"
Sealed the 3rd May 1872, and dated the 8th November 1871.
PROVISIONAL SPECIFICATION left by the said Charles Davage at the
Office of the Commissioners of Patents, with his Petition, on the
8th November 1871.
I, CHARLES DAVAGE, of Sheffield, in the County of York, Steel Forge-
5 man, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN MACHINERY FOR FORMING OR SHAPING AXLES AND OTHER ARTICLES IN
STEEL OR IRON," to be as follows :-
-

page_text: place a piece of heated steel or iron between two plates; the upper
surface of the lower one and the under surface of the upper one have
corresponding projections according to the impressions required to be made
upon the piece of heated metal inserted, and by horizontal motion of the
plates, causing a compression of the projecting surfaces, I roll the axle or
article into the required form; or rolls with projections adapted to them
might be substituted for the plates. I prefer to make the plates of cast
or wrought iron or steel.
The projections are made thick enough to suit any section intended to
be forged or rolled. The edges of the plates or ends of the rolls (as the
case may be) are worked from frictional bearings and driven by a worm
or rack as may be required for the purpose.
The piece of heated steel or iron is placed transversely on the surface
of the lower plate, where the projections are the shallowest, and the
plates or rolls then slide or roll over the metal, thereby compressing it
into the required form. The projections referred to are cast or forged on
the plates and different plates or rolls have to be employed according
to the shape or pattern required.
The wheels are driven by means of shafts or pistons working in
bearings above the upper and below the under plate or roll and upon
which the drums are fixed, the bands being placed upon the drums in
the usual manner.
I purpose to fix the aforesaid machinery on a strong cast-iron base

page_text: year of our Lord One thousand eight hundred and seventy-one, in the
thirty-fifth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Charles Davage, Her special licence that
I, the said Charles Davage, my executors, administrators, and assigns,
or such others as I, the said Charles Davage, my exccutors, adminis-
trators, 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, excrcise, and vend,
within the United Kingdom of Great Britain and Ircland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN MACHINERY
POR FORMING OR SHAPING AXLES AND OTHER ARTICLES IN STEEL OB IRON," upon
the condition (amongst others) that I, the said Charles Davage, my
executors or administrators, by an instrument in writing under my, or
their, or one of their hands and seals, should particularly' describo 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 Charles Davage, do hereby declare the
nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement, reference being had to the accompanying Drawing
forming a part of this Specification.
The object of this Invention is to give the necessary shape or form to
axles or other articles in steel or iron, or other suitable materials. Το
accomplish this object I pláce a piece of steel or iron, or other suitable
material, heated or cold, between two plates; the upper surface
of the lower one and the under surface of the upper one having corrc-
sponding projections according to the impressions required to be made
upon the piece of heated metal inserted, and by horizontal motion of the
plates, causing a compression of the projecting surfaces, or otherwise
where indentations or grooves are employed, I roll the axle or article
into the required form; or rolls with projections or indentations adapted
to them might be substituted for the plates. I prefer to make the plates
of cast or wrought iron or steel.

page_text: be forged or rolled. The edges of the plates or ends of the rolls (as the
case may be) are worked from frictional bearings and driven by a worm
or rack, as may be required for the purpose.

iron, steel, or other suitable materials, as herein set forth.
In witness whereof, I, the said Charles Davage, have hereunto set
my hand and seal, this Sixth day of May, in the year of our Lord
One thousand eight hundred and seventy-two.
CHARLES DAVAGE. (L.S.)
