Iй- PROVED MACHINERY FOR LOADING AND DISCHARGING CARGO FROM SHIPS AND
Year: 1865

page_text: LETTERS PATENT to George Elliot, of Betley Hall, in the County of
Stafford, Colliery Owner, and Robert Pattison Clark, of the Borough of
Newcastle-upon-Tyne, Mechanical Engineer, for the Invention of "Iй-
PROVED MACHINERY FOR LOADING AND DISCHARGING CARGO FROM SHIPS AND
'
Sealed the 21st November 1865, and dated the 26th May 1865.
PROVISIONAL SPECIFICATION left by the said George Elliot and Robert
Pattison Clark at the Office of the Commissioners of Patents, with
their Petition, on the 26th May 1865.
We, GEORGE ELLIOT, of Betley Hall, in the County of Stafford, Colliery
Owner, and ROBERT PATTISON CLARK, of the Borough of Newcastle-upon-
Tyne, Mechanical Engineer, do hereby declare the nature of the said Invention
for "IMPROVED MACHINERY FOR LOADING AND DISCHARGING CARGO FROM SHIPS AND
OTHER VESSELS," to be as follows:-
Our machinery is intended to be worked by steam in order to effect the
rapid loading and discharge of cargoes, and applies more particularly to the
discharge of coal from colliers. It consists of a shaft or derrick carrying a
pulley at top, and fitting at bottom into a socket, or otherwise connected to a
foot or bed, so that the shaft may be more or less inclined, according to

page_text: requirement. At the rear of the shaft we fit a winch, and work the winch
by means of cylinders supplied with steam from the ship's boilers, or
from other boilers, should the collier not be a steam vessel. A rope or chain
is carried from the winch over the pulley at the head of the shaft, and is
made fast to a cage or bucket, or carries a hook or hooks according to the
cargo to be acted on. The shaft is held at the incline desired by guys
carried from the upper end. We prefer to place two shafts over each hatch-
way or opening into the hold, and by shafting to work several winches from
one cylinder, or pair of cylinders. We adapt clutch gearing to each winch
to throw it into and out of gear as required. Supposing our machinery applied
to discharge coal from a collier, a bucket is lowered by the winch into the
hold; on its being filled it is run up by the winch above the level of a stage
or platform which we erect above the deck, and there held suspended; a man
pushes the bucket to the side and tilts its contents into the coal measure or
shoot. The bucket is returned over the hold to be lowered, filled, raised, and
emptied as before.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said George Elliot and Robert Pattison Clark in the Great Seal
Patent Office on the 25th November 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, GEORGE_
ELLIOT, of Betley Hall, in the County of Stafford, Colliery Owner, and
ROBERT PATTISON CLARK, of the Borough of Newcastle-upon-Tyne, Mechanical
Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-sixth day of May, in the year of our Lord
One thousand eight hundred and sixty-five, in the twenty-eighth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
us, the said George Elliot and Robert Pattison Clark, Her special licence.
that the said
executors,
administrators, and assigns, or such others as we, the said George Elliot and
Robert Pattison Clark, our 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 "IMPROVED
MACHINERY FOR LOADING AND DISCHARGING CARGO FROM SHIPS AND OTHER VESSELS,"
"

page_text: upon the condition (amongst others) that we, the said George Elliot and
Robert Pattison Clark, or one of us, our executors or administrators, by an
instrument in writing under our, or one of our 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 we, the said George Elliot and Robert Pattison
Clark, do hereby declare the nature of our said Invention, and in what
manner the same is to be performed, to be particularly described and ascer-
ained in and by the following statement thereof, reference being had to the
Drawings hereunto annexed, that is to say :-
Our machinery is intended to be worked by steam in order to effect the
rapid loading and discharge of cargoes, and applies more particularly to the
discharge of coal from colliers. It consists of a shaft, derrick, or boom upon
the mast, carrying a pulley at top, and fitting at bottom into a socket, or
otherwise connected to a foot or bed, so that the shaft may be more or less
inclined, according to requirement; at the rear of the shaft we fit a winch,
and work the winch by means of cylinders supplied with steam from the
ship's boilers, or from other boilers should the collier not be a steam vessel.
A rope or chain is carried from the winch over the pulley at the head of the
shaft, and is made fast to a cage, bucket or basket, or carries a hook or hooks
according to the cargo to be acted on. The shaft is held at the incline
desired by guys carried from the upper end. We prefer to place two shafts,
derricks, or booms over each hatchway or opening into the hold, and by
shafting to work several winches from one cylinder, or pair of cylinders. We
adapt clutches or cones gearing to each winch to throw it into and out of
gear as required.
Figure 1 is a side elevation in section, and Figure 2 a plan of a collier
shewing our machinery fitted thereto. The fore hatchway has one shaft,
while each of the other hatchways has shafts with two balls or drums applied
to it. A, A, are shafts or derrieks rounded at bottom and fitting into concave
sockets a, a; at top the shafts carry pulleys 6, 6, over which a chain passes,
one end of the chain is hooked to a bucket B, while the other end is fastened
to a barrel or drum C. The barrels are put in and out of gear with shafting D
by clutches or cones, worked by handles c, c. The shafting is driven by steam
engines E, E, supplied with steam from the boiler F. In the case of steam
vessels the shafting could be driven by belts from the main engine if required.

page_text: G, G, are guys for holding the shafts A, A, at the incline required. Sup-
posing our machinery applied to discharge coal from a collier, a bucket is
lowered by the winch into the hold, on its being filled it is run up by the
winch above the level of a stage or platform H, which we erect above the
deck, and there held suspended; a man pushes the bucket to the side and
'tilts its contents into the coal measure or shoot. The bucket is returned over
the hold to be lowered, filled, raised, and emptied as before. To load cargo
we sometimes erect our machinery on the wharf or stage from which it
is to be shipped.
And having now described the nature of our said Invention, and in what
manner the same is to be performed, we declare that we claim the combina-
tion of machinery substantially in manner herein-before described for loading
and discharging cargo.
* In witness whereof, I, the said Robert Pattison Clark, for myself and
on behalf of the said George Elliot, have hereunto set my hand and
seal, this Twenty-third day of November, One thousand eight hundred
and sixty-five.
K. P. CLARK. (L.S.)
