IMPROVEMENTS IN DE MACHINERY ENDLAYED PAD DIPROSE
Year: 1860

page_text: LETTERS PATENT to William Spurrier, of Birmingham, in the County
of Warwick, Manufacturer, for the Invention of "IMPROVEMENTS IN
DE MACHINERY ENDLAYED PAD
DIPROSE
"
Sealed the 17th July 1860, and dated the 4th February 1860.
PROVISIONAL SPECIFICATION left by the said William Spurrier at the
Office of the Commissioners of Patents, with his Petition, on the
4th February 1860.
I, WILLIAM SPURRIER, of Birmingham, in the County of Warwick, Manu-
facturer, do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN SHAPING METALS, AND IN MACHINERY EMPLOYED FOR THAT PURPOSE," to be
as follows:-
My Invention consists in shaping metals by the use of the implements or
machinery herein-after explained in place of the hand hammer, and hand
swages ordinarily employed for that purpose. My Invention is applicable to
the manufacture of globular and other shaped vessels from sheet metal, as well
as to the formation of borders and other shapes upon articles of sheet metal.
In carrying my Invention into effect, I fix a hammer head or swage upon
the long arm of a lever turning upon a horizontal axis. The short arm of the
said lever, is operated upon by means of cambs. or teeth on the periphery of a
wheel made to rotate by steam or other power. A rapid reciprocating motion
is given to the hammer or swage by the said wheel, and the metal to be shaped
is subjected to the percussive action of the hammer or swage, and thereby
shaped in the required manner. The metal operated upon is supported on
sand in bags or dies, or in any other convenient manner.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
SPURRIER, of Birmingham, in the County of Warwick, Manufacturer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourth day of February, in the year of our
Lord One thousand eight hundred and sixty, in the twenty-third year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said William Spurrier, Her special licence that I, the said
William Spurrier, my executors, adininistrators, and assigns, or such others
as I, the said William Spurrier, 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 SHAPING METALS, AND IN MACHINERY EMPLOYED
FOR THAT PURPOSE," upon the condition (amongst others) that I, the said William
Spurrier, 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 William Spurrier, 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:-
My Invention consists in shaping metals by the use of the machinery
berein-after described in place of the hand hammer and hand swages ordinarily
employed for that purpose. My Invention is especially applicable to the
manufacture of globular and other shaped vessels from sheet metal, as well as
to the formation of borders and other shapes upon articles of sheet metal.
In carrying my Invention into effect I fix a hammer head or swage upon
the long arm of a lever turning upon a horizontal axis. The short arm of the
said lever is operated upon by means of cams or teeth on the periphery of a
wheel, made to rotate by steam or other power. The said cams or teeth

page_text: depress the short end of the said lever, and raise the long end of the said lever
carrying the hammer or swage. As the cams or teeth escape from the short
end of the lever the long and hammer end falls. A rapid reciprocating
motion is thus given to the hammer or swage by the said wheel, and the
metal to be shaped is subjected to the percussive action of the hammer or
swage, and thereby shaped in the required manner. The metal operated upon
is supported on sand in bags or dies, or in any other convenient manner.
Although I prefer to work the hammer or swage by means of a lever,
operated upon by cams or teeth on the periphery of a wheel, yet I sometimes
work the hammer or swage in the following manner, that is to say, I attach
the hammer or swage to the bottom of a vertical rod or shaft, which is capable
of a vertical motion in guides made in suitable framing. By means of tappets
or projecting pieces on the said rod or shaft, it may be raised by cams or
toothed wheels and allowed to fall by its own weight, and that of the hammer
or swage attached to it.
By the use of the machinery herein-before described, the workman has great
facility in moving about the article being operated upon, having both hands at
liberty. He can thereby effect the shaping of the metal with greater exactness
and rapidity than by the ordinary method.
I claim as my Invention the improvements in and machinery employed for
shaping metals herein-before described, that is to say, shaping metals by
means of hammers or swages fixed on levers or vertical shafts, the said levers
or shafts being rapidly raised and allowed to fall by cams or toothed wheels,
and thereby made to strike and shape the metal being operated upon.
In witness whereof, I, the said William Spurrier, have hereunto set my
hand and seal, this Thirty-first day of July, in the year of our Lord
One thousand eight hundred and sixty.
Witness,
GEORGE SHAW.
WILLIAM SPURRIER. (L.S.)
