Year: 1861

page_text: LETTERS PATENT to William Cory, junior, of the Coal Exchange,
London, for the Invention of "IMPROVEMENTS IN VESSELS AND MACHINERY
FOR UNLOADING COLLIERS AND OTHER VESSELS CONTAINING COALS."
Sealed the 28th November 1861, and dated the 18th September 1861.
PROVISIONAL SPECIFICATION left by the said William Cory at the
Office of the Commissioners of Patents, with his Petition, on the 18th
September 1861.
I, WILLIAM CORY, junior, of the Coal Exchange, London, do hereby
declare the nature of the Invention for "IMPROVEMENTS IN VESSELS AND
MACHINERY FOR UNLOADING COLLIERS AND OTHER VESSELS CONTAINING COALS," to
be as follows:-
This Invention has for its object improvements in vessels and machinery for
unloading colliers and other vessels containing coals, and consists of combining
a suitable construction of floating vessel or platform with proper cranes and
weighing machinery, together with rail or tramways, in order that colliers or
other vessels containing coals may come alongside whilst barges. are on either
side of both ends of the vessel or floating platform; and when desired the coals
in descending from this vessel or platform into the barges may be screened by
descending on screens suitably placed at each end of the vessel or floating
platform by which the cranes and machinery are carried.

page_text: In constructing a suitable floating vessel or floating platform for the purpose
of the Invention, it is necessary that it should be of considerable beam as
compared with its length, and with two angular or inclined ends, in order to
obtain great stability, and so that great weights may be lifted by the cranes
on ono side without interfering materially with the horizontal position of the
deck or platform. Cranes are applied on either side of the deck or platform
in such manner that their jibs may, on the one hand, be capable of projecting
over the side to such an extent as to come sufficiently over the collier or other
vessel containing coals alongside which are to be unloaded therefrom, and
conveyed directly into the barges lashed to the ends of the floating platform or
vessel. The jibs of the cranes are not, however, to be capable of turning in-
board to such an extent as to interfere one with the other, there being, as
before stated, cranes on each side of the vessel or floating platform.
The arrangement and construction of vessel and machinery preferred are as
follows: Tho deck or platform of the floating vessel is about ninety feet
beam, and two hundred and fifty feet long, having a flat or nearly flat
bottom, in order that the vessel may be very stable and draw as little
water as may be; and in order that such a vessel may be anchored
in a river in such a position that colliers and other vessels carrying coals
may pass on either side, and be made fast on either side, and in such
manner also that by reason of the angular or inclined bows and stern two
barges may be made fast at cach end, one on either side at the bow and the
storn in positions inclined to the sides of the floating vessel. It is preferred to
employ three cranes at each sido of the deck or platform, so that the jibs of
the two nearest ends may lift directly from the colliers or other vessels carrying
coal into the two barges at the two ends or over the inclined shoots or screens
interposed between the deck or platform and the barges, and that the jib of
the central crane on each side shall be capable of lifting a truck or suitable
receiver loaded with coal out of a collier or other vessel, and to place the same
on a rail or tramway laid in a direction from end to end of the vessel or plat-
form. Though the construction of the cranes used may be varied, it is
preferred to employ hydraulic cranes constructed to weigh and indicate the
weight of each load.
By this combination and arrangement provision is made for simultaneous
loading of four barges with coal, two at each end of the vessel or floating plat-
form, from colliers or other vessels loaded with coal, the coals in each case
when desired being screened.

by the said William Cory in the Great Seal Patent Office on the
18th March 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
CORY, junior, of the Coal Exchange, London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighteenth day of September, in the year of our
Lord One thousand eight hundred and sixty-one, in the twenty-fifth year of
Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said William Cory, Her special licence that I, the said William
Cory, my executors, administrators, and assigns, or such others as I, the
said William Cory, 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 VESSELS AND MACHINERY FOR UNLOADING COLLIERS AND OTHER
VESSELS CONTAINING COALS," upon the condition (amongst others) that I, the
said William Cory, 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 Cory, 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 fol-
lowing statement thereof, that is to say :-
This Invention has for its object improvements in vessels and machinery for
unloading colliers and other vessels containing coals, and consists of combining
a suitable construction of floating vessel or platform with proper cranes and
weighing machinery, together with rail or tramways, in order that colliers
or other vessels containing coals may come alongside whilst barges are on
either side of both ends of the vessel or floating platform, and when desired
the coals in descending from this vessel or platform into the barges may
be screened by descending on screens suitably placed at each end of the
vessel or floating platform by which the cranes and machinery are carried.

in such manner that their jibs may be capable of projecting over the side to
such an extent as to como sufficiently over the collier or other vessel containing

lashed to the ends of the floating platform or vessel. The jibs of the cranes
are not, however, to be capable of turning inboard to such an extent as to
interfere one with the other, there being, as before stated, cranes on each side
of the vessel or floating platform.
The arrangement and construction of vessel and machinery preferred are as
follows: The deck or platform of the floating vessel is about ninety feet
beam, and two hundred and fifty feet long, having a flat or nearly flat bottom,
in order that the vessel may be very stable and draw as little water as may
be, and in order that such a vessel may be anchored in a river in such a
position that colliers and other vessels carrying coals may pass on either side,
and be made fast on either side, and in such manner also that by reason of the
angular or inclined bows and stern two barges may be made fast at each end,
one on either sido at the bow and the stern, in positions inclined to the sides
of the floating vessel. It is preferred to employ three cranes at each side of
the deck or platform, so that the jibs of the two nearest the ends may lift
directly from the colliers or other vessels carrying coal into the two barges at
the two ends or over the inclined shoots or screens interposed between the
deck or platform and the barges, and that the jib of the central crane on each
side shall be capable of lifting a truck or suitable receiver loaded with coal out
of a collier or other vessel, and to place the same on a rail or tramway laid in
a direction from end to end of the vessel or platform. Though the con-
struction of the cranes used may be varied, it is preferred to employ hydraulic
cranes constructed to weigh and indicate the weight of each load.
By this combination and arrangement provision is mado for simultaneous
loading of four barges with coal, two at each end of the vessel or floating plat-
form, from colliers or other vessels loaded with coal, the coals in each case
when desired being screened.
Having thus stated the nature of my Invention, I will proceed more fully
to describe the manner of performing the same.
