Year: 1853

page_text: LETTERS PATENT to George Rock Lucas, of Dronfield, near
Sheffield, in the County of Derby, for the Invention of "IMPROVE-
MENTS IN THE METHOD OF RAISING WATER AND OTHER MATERIALS
FROM MINES.
Sealed the 17th June 1853, and dated the 18th March 1853.
PROVISIONAL SPECIFICATION left by the said George Rock Lucas
at the Office of the Commissioners of Patents, with his Petition,
on the 18th March 1853.
I, GEORGE ROCK LUCAS, of Dronfield, near Sheffield, in the County
of Derby, do hereby declare the nature of the Invention of "IMPROVE-
MENTS IN THE METHOD OF RAISING WATER AND OTHER MATERIALS FROM
MINES" to be as follows:-
I introduce a tank or vessel under the chair or cradle used for
carrying up the minerals. In the bottom of such tank or vessel is a
valve with a rod, having at its upper part a cross bar, a few inches
under the chair, so that when the cross bar drops upon the rests (at
the top of the shaft) it lifts the valve and allows the water to escape.
Near the upper part of the shaft of the mine is a receiver or trough,
which, when the tank has been raised beyond it, is caused to descend
under the tank, and to receive the water to conduct it away into the

page_text: drain. When the chair is again lifted from the rests ready to descend
the shaft of the mine, the receiver or trough falls back into the end of
the drain.
A reservoir is formed at the bottom of the shaft of the mine, into
which the water is collected from the workings of the mine; the tank.
descends down into this reservoir, and the water fills the tank or vessel,
and at the same time the mineral is loaded upon the chair.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said George Rock Lucas, in the Great Seal Patent
Office, on the 17th September 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
GEORGE ROCK LUCAS, of Dronfield, near Sheffield, in tho County of
Derby, send greeting.
WHEREAS er most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighteenth day of March, in the year of
our Lord One thousand eight hundred and fifty-three, in the sixteenth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, tne said George Rock Lucas, Her special licence that I,
the said George Rock Lucas, my executors, administrators, and assigns,
or such others as 1, the said George Rock Lucas, my executors, 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, 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
METHOD OF RAISING WATER AND OTHER MATERIALS PROM MINES," upon
the condition (amongst others) that I, the said George Rock Lucas,
by an instrument in writing under my hand and seal, should particu-
larly 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 Rock Lucas, do hereby

page_text: 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):
I introduce a tank or vessel under the chair or cradle used for
carrying up the minerals. In the bottom of such tank or vessel is a
valve with a rod, having at its upper part a cross-bar, so that when
the cross-bar drops upon the rests (at the top of the shaft) it lifts the
valve and allows the water to escape. Near the upper part of the
shaft of the mine is a receiver or trough, which, when the tank has
been raised beyond it, is caused to descend under the tank, and to
receive the water to conduct it away into the drain. When the chair
is again lifted from the rests ready to descend the shaft of the mine, the
receiver or trough falls back into the end of the drain. A reservoir is
formed at the bottom of the shaft of the mine, into which the water is
collected from the workings of the mine, the tank descends down into
the reservoir, and the water fills the tank or vessel, and at the same
time the mineral is loaded upon the chair.
Having thus stated the nature of my Invention, I will now proceed
to describe the drawing hereunto annexed in the various Figures, of
which the same letters are in all instances used to indicate similar parts.
Figure 1, is a plan; Figure 2, a section, taken through the line a, b,
in Figure 1; Figure 3, is another section, taken through the line c, d,
in Figure 1; and Figure 4, is a section, taken at right angles thereto.
a, is a tank or vessel, introduced under the chair or cradle b, used for
carrying up the minerals, &c. At the bottom of such tank or vessel is
a valve c, to which is attached a rod d, which passes through a cross-
bar e, and is connected thereto by a pin, a few inches below the cradle
or chair b, which is placed in such manner that on the lowering of
the cradle b, the valve c, will be raised by reason of the bar e, coming
in contact with the rests f, f, by which the water raised by the vessel a,
is allowed to escape into a receiver or trough g, which, when the tank
or vessel-a, has been raised beyond it, is caused to turn on its axis at h,
and descend below the valve c, of the tank or vessel a, and form a
means of conducting the water from the vessel a, into the drain ;
attached to the lever i, on the axis h. of the receiver g, is a rod j,

page_text: which slides in bearings k, k; at the upper end of the rod j, there is a
step j', formed with a rule joint, so that the rising of the cross bar e,
only influences it sufficient to raise the step ji, on its axis to allow of the
passage upwards of the cradle b; but when the lowering of the cradle b,
und cross bar e, takes place, the step j', will receive the cradle b,
and be borne down thereby, and carry with it the rod and lever j, i, as
shown, and turn the receiver g, on its axis h, into the position shown by
Figure 3, and so conduct the water, as it is discharged from the vessel
or tank a, into the drain r. , is a reservoir to collect the water from
the workings of the mine; and the vessel a, descends and becomes
filled, as shown by Figures 2, and 4; and by the rising of the vessel a,
the valve c, will be closed as before.
Having thus described the nature of my said Invention, and the
manner of performing the same, I would have it understood that I do
not claim any of the separate parts herein described, and the details
may be varied without departing from my Invention. But what I
claim is, the combination of apparatus herein described, for raising
water and other materials out of mines.
In witness whereof, I, the said George Rock Lucas, have here-
unto set my hand and seal, this Fifteenth day of September, in
the year of our Lord One thousand eight hundred and fifty-
three.
GEORGE ROCK LUCAS. (L.B.)
Witness, JOHN COOKERTON.
