IMPROVEMENTS IN RAISING WEIGHTS, APPLICABLE TO STAMPING OR CUTTING METALS, AND OTHER SIMILAR PURPOSES
Year: 1857

page_text: LETTERS PATENT to George Ireland, of Birmingham, in the County of
Warwick, for the Invention of "IMPROVEMENTS IN RAISING WEIGHTS,
APPLICABLE TO STAMPING OR CUTTING METALS, AND OTHER SIMILAR PURPOSES."
Sealed the 15th December 1857, and dated the 24th June 1857.
PROVISIONAL SPECIFICATION left by the said George Ireland at the Offico
of the Commissioners of Patents, with his Petition, on the 24th Junc
1857.
I, GEORGE IRELAND, of Birmingham, in the County of Warwick, do hereby
declare the nature of the Invention for "IMPROVEMENTS IN RAISING WEIGHTS,
APPLICABLE TO STAMPING OR CUTTING METALS, AND OTHER SIMILAR PURPOSES,"
to be as follows:-
This Invention has for its object improvements in raising weights, when
applied to stamping and cutting metals, crushing minerals, or other purposes.
Now, according to this, my Invention, a drum or pulley is fixed upon a shaft,
driven continuously by steam or other power, around which drum or pulley I
place a loose hoop or ring flexible or not, which, being of rather larger
diameter than the drum or pulley, allows the same to revolve freely within
it. A strap or rope is passed over this loose hoop or ring, having attached
to one end of it the hammer or weight to be raised; the other end hanging
free. When in operation the free end of the strap or rope is tightened and
drawn downward, producing friction between the loose ring or hoop and the
drum or pulley, and thus raising the weight or hammer to any desired
height, which being attained the end of the strap or rope is released, and the
hammer or weight is liberated and falls.

by the said George Ireland in the Great Seal Patent Office on the
24th December 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
IRELAND, of Birmingham, in the County of Warwick, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fourth day of June, in the year of our Lord
One thousand eight hundred and fifty-seven, in the twenty-first year of Her
reign, did for Herself, Her heirs and successors, give and grant unto me,
the said George Ireland, Her special licence that I, the said George Ireland,
.my executors, administrators, and assigns, or such others as I, the said
George Ireland, 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 RAISING WEIGHTS, APPLICABLE TO STAMPING OR CUTTING
METALS, AND OTHER SIMILAR PURPOSES," upon the condition (amongst others)
that I, the said George Ireland, 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 George Ireland, 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 :-
This Invention has for its object improvements in raising weights, when
applied to stamping and cutting metals, crushing minerals, or other purposes.
Now, according to this my Invention, a drum or pulley is fixed upon a shaft,
driven continuously by steam or other power, around which druin or
pulley i
place a loose hoop or ring, flexible or not, which being of rather larger
diameter than the drum or pulley, allows the same to revolve freely within it.
A strap or rope is passed over this loose hoop or ring, having attached to one
end of it the hammer or weight to be raised, the other end hanging free.
When in operation the free end of the strap or rope is tightened and drawn
<ownward, producing friction between the loose ring or hoop, and the drum

page_text: or pulley, and thus raising the weight or hammer to any desired height,
which being attained, the end of the strap or rope is released, and the hammer
or weight is liberated and falls.
Having thus stated the nature of my said Invention, I will proceed more
fully to describe the manner of performing the same.
DESCRIPTION OF THE DRAWING.
Figure 1 shows a front elevation, and Figure 2 a side elevation, of apparatus
arranged or combined suitably for carrying out my Invention. The stamping
apparatus is similar to what is ordinarily used, and will not require any
description. a is a shaft, receiving motion from a steam-engine or other
power, by a strap acting on the drum or pulley b, fixed to the shaft, or in any
convenient manner; c is a pulley fixed to the shaft a, and which constantly
revolves with the shaft. On this pulley is a ring or hoop d, of somewhat
larger diameter than the pulley c, so that the pulley c can revolve within the
ring or hoop d, without carrying the hoop or ring round with it; e is a strap
or band attached to the weight or stamp f, there being at the other end of the
strap or band a loop g, by which the workman pulls the band or strap tightly
on to the ring or hoop, which will cause the inner surface of the ring or hoop
to be pressed in contact with the upper surface of the pulley c. The friction
thereby obtained will cause the hoop or ring d to rotate with the pulley c, and
the weight or stamp will be raised by the power which drives the shaft a.
The workman will thus be relieved from much of the effort heretofore
required in raising the weight or stamp, and on the workman releasing the
strap or band, the weight or stamp will fall as heretofore.
In witness whereof, I, the said George Ireland, have hereunto set my
hand and seal, this Eighteenth day of December, in the year of
our Lord One thousand eight hundred and fifty-seven.
Witness,
JAMES BALLENY ELKINGTON,
of Birmingham.
GEORGE IRELAND. (L.S.)
