for an Invention of AN IMPROVED METHOD OF COALING STEAM SHIPS AND
A CORVE OR CARRIAGE THEREFOR
PROVISIONAL SPECIFICATION left by the said Samuel Plimsoll at the
Office of the Commissioners of Patents on the 1st February 1883.
SAMUEL PLIMSOLL of 3 Whitehall Gardens London S.W. AN IMPROVED
METHOD OF COALING STEAM SHIPS AND A CORVE OR CARRIAGE THEREFOR
I prepare a corve kettle or skip which may be made of wood iron or steel and
be in shape square or round (for preference a section of an upright cylinder) with
the bottom closed first being narrowed to a diameter a little smaller than the
inside diameter of the combing of the coal bunker-The Corve is carried on wheels
at such a height from the deck of the ship or the ground as shall just allow the
edge to clear the edge of the combing under the aperture in the bottom of the
corve I place a plate or damper held firmly in its place by a spring springs or
lever the edge of the damper is turned down so that when the corve is pushed
over the combing-the top edge of the combing holds the damper fast and the
corve passing on, the hole in the bottom becomes uncovered and the coal instantly
falls into the hold or bunker beneath, the spread of dust I prevent either by fitting
the bottom of the cylinder to the top edge of the combing with precision, or by a
slight curtain of canvas suspended from the corve, or attached to a ring round the
combing which is thrown upwards by the advent of the Corve until it reaches the
bottom of the latter; The damper during the descent of the charge of coal being
held back by a spring or lever which is released by withdrawing it, the Corve,
instantly returns to its places and closes the aperture in the bottom of the corve
just as the slide in the neck of an old fashioned powder flask does-I would also
close the aperture by a Globe of a slightly larger diameter than the aperture itself-
it should be held up to its place by a chain passing upwards through the charge of
coal and secured by a catch to a bar of iron or other material over head, that is
crossing the top of the Corve & having the bottom or protruding part cut away
as far as in practice may be found desirable-When the bottom of the Corve is over
the combing of the bunker the suspended globe or cone is liberated, falls through
into the hold far enough to be out of the way of the descending coal, the coal
discharged the slack of the Chain is hauled up and secured

SAMUEL PLIMSOLL of 3 Whitehall Gardens, London, S.W. "AN IMPROVED

the bottom closed first being narrowed to a diameter a little smaller than the
inside diameter of the combing of the coal bunker--The Corve is carried on wheels
at such a height from the deck of the ship or the ground as shall just allow the
edge to clear the edge of the combing-Under the aperture in the bottom of the
corve I place a plate or damper held firmly in its place by a spring springs or
lever the edge of the damper is turned down so that when the corve is pushed
over the combing-the top edge of the combing holds the damper fast and the corve
passing on, the hole in the bottom becomes uncovered and the coal instantly falls

bottom of the cylinder to the top edge of the combing with precision, or by a

the combing which is thrown upwards by the advent of the corve until it reaches
the bottom of the latter; The damper during the descent of the charge of coal
being held back by a spring or lever which is released by withdrawing it, the
Corve, instantly returns to its place and closes the aperture in the bottom of the
corve just as the slide in the neck of an old fashioned powder flask does-I would
also close the aperture by a Globe of a slightly larger diameter than the aperture
itself it should be held up to its place by a chain passing upwards through the
charge of coal and secured by a catch to a bar of iron or other material overhead,
that is crossing the top of the corve and having the bottom or protruding part cut
away as far as in practice may be found desirable-when the bottom of the Corve
is over the the Combing of the bunker the suspended globe or Cone is liberated,
falls through into the hold far enough to be out of the way of the descending coal,
the coal discharged the slack of the chain is hauled up and secured
In witness whereof I the said Samuel Plimsoll have hereunto set my hand and
seal this first day of August in the year of Our Lord One thousand eight hundred
and eighty three
