page_text: LETTERS PATENT to Sir John Coode, Knight, of 5, Westminster Chambers,
Victoria Street, in the City of Westminster, for an Invention of "IMPROVE-
MENTS IN APPARATUS FOR LANDING OR DELIVERING SAND, MUD, SHINGLE,
GRAVEL, OR SUCH LIKE MATERIALS FROM BARGES AND OTHER VESSELS,
ESPECIALLY SUCH AS MAY HAVE BEEN RAISED BY DREDGING."
PROVISIONAL SPECIFICATION left by the said Sir John Coode at the Office
of the Commissioners of Patents on the 18th March 1880.
Sir JOHN COODE, Knight, of 5, Westminster Chambers, Victoria, Street, in the
City of Westminster. "IMPROVEMENTS IN APPARATUS FOR LANDING OR DELIVERING
SAND, MUD, SHINGLE, GRAVEL, OR SUCH LIKE MATERIALS FROM BARGES AND OTHER
VESSELS, ESPECIALLY SUCH AS MAY HAVE BEEN RAISED BY DREDGING."
This Invention has for its object improvements in apparatus for landing or
delivering sand, mud, shingle, gravel, or such like materials from barges and other
vessels, especially such as may have been raised by dredging.
For this purpose I construct or adapt a barge or other vessel in such a manner
that by the admission of water through trunks or pipes, and by the regulation of
doors or valves, streams of water may be caused to sweep freely through the body
and over the bottom of the barge or other vessel, but preferably and for the most
part from both its ends towards the centre.
At or near the centre of the barge or other vessel I fix a trunk or pipe, preferably
in a vertical position, and open at both top and bottom, but having a passage or
passages communicating with the external water, and in this trunk or pipe I place
the suction pipe of the pump by means of which the materials are to be delivered
when mixed with water, or the suction pipe of the pump may be coupled up
directly with the trunk or pipe fixed at or near the centre of the barge or other
vessel, as above described.
When a barge or other vessel so constructed is to be emptied of sand, mud,
gravel, shingle, or other materials capable of being carried along with a current of
water, the suction pipe of a pump is inserted loosely within the central trunk or

page_text: pipe, or the suction pipe of the pump is coupled up with the upper end of the central
trunk or pipe, the doors or valves being then fully open; the pump on being put
into action will draw away water heavily charged with sand, mud, shingle, gravel,
or such like substances from the bottom of the barge towards the central (and
preferably vertical) trunk or pipe before described, and will discharge it into or
through pipes or troughs, by means of which it may be conveyed to wherever the
sand, mud, shingle, gravel, or such like substances are required to be deposited or
delivered. Shortly after the operation has commenced it becomes necessary to
partially close the doors or valves in a greater or less degree in order that the
streams or stream of water may be regulated in due proportion to the quantity of 1
materials remaining to be discharged.

This Invention has for its object improvements in apparatus for landing or
delivering sand, mud, shingle, gravel, or such like materials from barges and other
vessels, especially such as may have been raised by dredging.
For this purpose I construct or adapt a barge or other vessel, in such a manner
that by the admission of water through trunks or pipes, and by the regulation of
doors or valves, streams of water may be caused to sweep freely through the body
and over the bottom of the barge or other vessel, but preferably and for the most
part from both its ends towards the centre.
At or near the centre of the barge or other vessel I fix a trunk or pipe, preferably
in a vertical position, and open at both top and bottom, and in this trunk or pipe
place the suction pipe of the pump or other lifting apparatus, by means of which
the materials are to be delivered when mixed with water; or the suction pipe of
the pump may be coupled up directly with the trunk or pipe fixed at or near the
centre of the barge or other vessel, as above described.
When a barge or other vessel so constructed is to be emptied of sand, mud,
gravel, shingle, or other materials capable of being carried along with a current of
water, the suction pipe of a pump is inserted loosely within the central trunk or
pipe, or the suction pipe of the pump is coupled up with the upper end of the
central trunk or pipe, the doors or valves being then fully open; the pump on
being put into action will draw away water heavily charged with sand, mud,
shingle, gravel, or such like substances from the bottom of the barge towards the
central (and preferably vertical) trunk or pipe before described, and will discharge
it into or through pipes or troughs, by means of which it may be conveyed to
wherever the sand, mud, shingle, gravel, or such like substances are required to be
deposited or delivered. Shortly after the operation has commenced it becomes
necessary to partially close the doors or valves in a greater or less degree in order
that the streams or stream of water may be regulated in due proportion to the
quantity of materials remaining to be discharged.
.
In order that my Invention may be fully understood I have shewn in the
Drawing hereunto annexed a barge adapted for delivering sand, mud, shingle,
gravel, or such like materials in the manner above described.
Figure 1 is a plan of the barge; Figure 2, an end view; Figure 3, a side
elevation, and Figure 4, a vertical cross section of the same.
At the centre of the barge is a well or receptacle A for holding the sand, mud,
shingle, gravel, or such like material. The bottom of this receptacle is made to
incline downwards from its sides and ends to the centre, especially at its four
corners. At the centre is a vertical trunk or pipe B fixed to the bottom of the
well by angle irons, so that the lower end of the trunk or pipe is kept a few inches
away from the bottom of the well. The pipe B is also stayed near its lower end
by four stays C; these stays are triangular in cross section with one of the angles
of the triangle uppermost; they not only serve to stay the central pipe, but also
serve to support the sand, mud, shingle, gravel, or other material, and keep it
from bearing too heavily upon the bottom of the central part of the hopper, so that
the material may not get bound at this point and prevented from moving up to
the central pipe. At the two opposite sides of the receptacle are two valves D,
which can be opened and closed by the turning of hand wheels E, as shewn at

page_text: Figure 1, or other mechanical contrivances might be used for opening and closing
valves or sluices for admitting water into the receptacle. When the valves are
opened and water admitted into the receptacle it is not allowed to flow in a straight|
course to the central pipe, but is diverted by projections G which stand up from
the bottom of the receptacle, as shewn at Figures 1 and 4; H is the suction pipe
of a pump or other lifting apparatus, which is lowered into the central pipe B when
the sand or other material is to be discharged from the barge. The lower end of
the suction has short legs projecting downwards from it, which keep its end a
short distance away from the bottom of the receptacle. When the pump is set in
action, and the valves D opened the contents of the well or receptacle A of the
barge are discharged as above explained. In addition jets of water from a force
pump may be directed against any of the contents which may have a tendency to
lodge or bang, so as to dislodge it and aid in its removal.
Having thus described the nature of my Invention and the manner of performing
the same, I would have it understood that I do not confine myself to the exact
details herein before given as to the form and construction of the barge shewn in
the Drawings, as barges of other form and other receptacles used for conveying
sand, mud, shingle, gravel, or such like materials may be constructed so that their
contents may be discharged in the same manner, that is to say, by means of water
allowed to flow through the body and over the bottom of the barge or receptacle
to the open bottom of a trunk or pipe at or near its centre, and up through which
the water and material carried along with it are raised and discharged, substantially
as described.
In witness whereof, I, the said Sir John Coode, have hereunto set my hand
and seal, this Seventh day of August, in the year of our Lord One thousand
eight hundred and eighty.
