IMPROVE- MENTS IN THE MANUFACTURE OF TILT AND FORGE HAMMER HEADS, AND IN HARSTS AND TAIL HOOPS
Year: 1870

page_text: LETTERS PATENT to Joseph Eaton Lee, of Oughtibridge, near
Sheffield, in the County of York, for the Invention of "IMPROVE-
MENTS IN THE MANUFACTURE OF TILT AND FORGE HAMMER HEADS, AND IN
HARSTS AND TAIL HOOPS."
Sealed the 13th June 1871, and dated the 14th December 1870.
PROVISIONAL SPECIFICATION left by the said Joseph Eaton Lee at
the Office of the Commissioners of Patents, with his Petition, on
the 14th December 1870.
I, JOSEPH EATON LEE, of Oughtibridge, near Sheffield, in the County
of York, do hereby declare the nature of the said Invention for "IM-
PROVEMENTS IN THE MANUFACTURE OF TILT AND FORGE HAMMER HEADS, AND IN
HARSTS AND TAIL Hoops," to be as follows:-
The improvements relate to the manufacture of hammer heads, harsts,
and tail hoops, used for the purposes of tilting and forging steel and
iron.
Hammer heads, harsts, and tail hoops are at present made of wrought
iron, their construction absorbing much time, labor, and expence, further

page_text: being made by hand labor and on account of the many pieces welded
together they cannot be produced twice alike as regards size, and so
forth, and much adjusting and loss in working has to take place before
the aforesaid implements are ready for work.
Now the improvements have for their object the removal of the above
defects, and consist in manufacturing the above-mentioned implements
of malleable iron.
The improvements may be carried into effect by making patterns in
metal or wood of the implements and castings made therefrom, such
castings being made malleable by the ordinary process at present
in use.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Joseph Eaton Lee in the Great Seal Patent Office
on the 14th June 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
EATON LEE, of Oughtibridge, near Sheffield, in the County of York,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourteenth day of December, in the
year of our Lord One thousand eight hundred and seventy, in the
thirty-fourth year of Her reign, did, for Herself, Her heirs and succes-
sors, give and grant unto me, the said Joseph Eaton Lee, Her special
licence that I, the said Joseph Eaton Lee, my executors, adminis-
trators, and assigns, or such others as I, the said Joseph Eaton Lee,
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 TILT AND FORGE HAMMER HEADS,
AND IN HURSTS AND TAIL HOOPs," upon the condition (amongst others)
that I, the said Joseph Eaton Lee, 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

page_text: six calendar months next and immediately after the date of the said
Letters Patent..
NOW KNOW YE, that I, the said Joseph Eaton. Lee, 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 :-
The improvements relate to the manufacture of hammer heads, hursts,
and tail hoops used for the purposes of tilting and forging steel and
iron.
Hammer heads, hursts, and tail hoops are at present made of wrought
iron, their construction absorbing much time, labor, and expense, further
being made by hand labor and on account of the many pieces welded
together they cannot be produced twice alike as regards size, and so
forth, and much adjusting and loss in working has to take place before
the aforesaid implements are ready for work.
Now the improvements have for their object the removal of the above
defects, and consist in manufacturing the above-mentioned implements
of malleable iron.
The improvements may be carried into effect by making patterns in
metal or wood of the implements and castings made therefrom, such
castings being made malleable by the ordinary process at present in
use.
The accompanying Drawings will serve to give an illustration of some
of the usual forms of hammer heads, hursts, and tail hoops.
Figures 1, 1, 2, and 3 are respectively side elevation, plan, sectional
elevation, and front elevation of a hammer head; Figures 4, 5, and 6
shew front elevation, side elevation, and section of a hurst; Figures 7,
8, and 9, front elevation, side elevation, and section of a tail hoop.
No Drawings of helves (which are also used for the purpose of tilting
and forging steel and iron) are given, but it is obvious that they may be
manufactured on the same principle.
These Drawings are given merely as an illustration of hammer heads,
hursts, and tail hoops, as the particular shape of the implements does
not in the least affect this Invention, which consists in the substitution
of malleable cast iron for wrought iron in the manufacture of hammer
heads, hursts, tail hoops, and helves.

page_text: The castings are made in the ordinary manner from iron, wood, or
other suitable patterns, and the said castings are then made malleable
by the ordinary process at present in use.
In witness whereof, I, the said Joseph Eaton Lee, have here-
unto set my hand and seal, this Twelfth day of June, in the 5
year of our Lord One thousand eight hundred and seventy-
one.
JOSEPH EATON LEE. (L.S.)
