I, WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake & Co, Patent Agents
Southampton Buildings in the County of Middlesex, do hereby declare the nature
of my invention for "IMPROVEMENTS IN APPARATUS FOR EFFECTING THE REMOVAL
OR TRANSPORT OF EARTH OR OTHER MATERIAL, CHIEFLY DESIGNED FOR USE IN
CONNECTION WITH A DREDGING MACHINE" to be as follows:-
This invention relates to apparatus for effecting the transport of earth or other
materials by water or compressed air, and has for its object to permit the intro-
duction of the materials which it is desired to transport into the delivery pipe in
amall quantities in proportion as they are dredged, instead of collecting them in a
receptacle as practised at the present time.
In order to make my invention understood, I have represented it, by way of
example, in the accompanying drawing in which
Figure 1 is a transverse section of the said apparatus.
Figure 2 a front view, and
Figure 3 a longitudinal section.
In these figures similar letters of reference indicate corresponding parts.
A is a cylinder closed at its two extremities and presenting at the lower part an
opening B on each side, which openings are of the same diameter as that of the
delivery pipe which it is desired to employ. A channel, the sectional area of which
is equal to half the area of the opening, extends through the cylinder in order to
augment the space of the compartment and to prevent any stoppage of the current
of water or air through the apparatus.
At the upper part of the cylinder is the opening C serving for the introduction
of the materials to be transported or removed.
A wheel D of cast or wrought iron is perfectly fitted within the cylinder and
has 5 or 6 vanes provided at their extremities with plates or pieces of india-rubber,

page_text: This wheel is rotated at a speed which corresponds to the quantity of materials
dredged. When the current is established in the pipes connected with the
apparatus, and the materials falling through the opening C are carried away by
the rotary motion of the interior wheel D, each compartment will be brought into
connection with the channel, whereby all the materials which are contained in the
said compartment are immediately carried away. The motion of the wheel being
combined with that of the buckets, there will never be any obstruction if care is
taken that the size of each compartment shall be larger than that of the buckets.
The water which necessarily fills the compartment which has just been emptied
escapes through an opening E arranged on one side of the apparatus, Figure 1, but
the water can escape through the upper part of the cylinder if desired. In order
to obviate stoppages by too voluminous materials it will be well, according to the
earth which is to be transported, to place at the fall of the buckets a crusher
composed of two cylinders having projections; or of any other form, in order to
divide the materials well before they enter the cylinder.

I, WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake & Co, Patent Agents,
Southampton Buildings, in the County of Middlesex do hereby declare the nature
of my invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
This invention relates to apparatus for effecting the transport of earth or other
materials by water or compressed air, and has for its object to permit the intro-
duction of the materials which it is desired to transport, into the delivery pipe in
small quantities in proportion as they are dredged, instead of collecting them in a
receptacle as practised at the present time.
In order to make my invention understood, I have represented it by way of
example, in the accompanying drawing in which
Figure 1 is a transverse section of the said apparatus.
Figure 2 a front view, and
Figure 3 a longitudinal section.
In these figures similar letters of reference indicate corresponding parts.
A is a cylinder closed at its two extremities and presenting at the lower part an
opening B on each side, which openings are of the same diameter as that of the
delivery pipe which it is desired to employ. A channel, the sectional area of which
is equal to half the area of the opening, extends through the cylinder in order to
augment the space of the compartment and to prevent any stoppage of the current
of water or air through the apparatus.
At the upper part of the cylinder is the opening C serving for the introduction
of the materials to be transported or removed.
A wheel D of cast or wrought iron, is perfectly fitted within the cylinder and
has 5 or 6 vanes provided at their extremities with plates or pieces of india-rubber
to prevent leakage between the ends of the said vanes and the surface of the
cylinder.
This wheel is rotated at a speed which corresponds to the quantity of materials
dredged. When the current is established in the pipes connected with the
apparatus, and. the materials falling through the opening C are carried away by
the rotary motion of the interior wheel D, each compartment will be brought into
connection with the channel, whereby all the materials which are contained in the
Baid compartment are immediately conducted away. The motion of the wheel
being combined with that of the buckets of a dredger there will never be any
obstruction if care is taken that the size of each compartment is greater than that
of a bucket. The water which necessarily fills the compartment which has just
been emptied escapes through an opening E arranged on one side of the apparatus,
Figure 1, but the water can escape through the upper part of the cylinder if
desired.

page_text: In order to avoid stoppage of the apparatus by the introduction of large pieces
of material, it will be advisable, according to the nature of the material which is
being removed, to place a crusher at the point at which the buckets of the dredger
discharge. This crusher may be composed of two cylinders having projections, or
it may be of any other form adapted to divide the materials before they enter the
cylinder.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, as communicated to
me by my foreign correspondent, I declare that what I claim is
The improved apparatus for effecting the removal or transport of dredged earth
or other material by dividing the same into small quantities and allowing these
divided portions to fall into a current of water or other fluid, which carries the
material to the point of discharge, the said apparatus comprising a cylinder A, a
wheel D having a number of vanes or wings and turning with slight friction in
the said cylinder, and a water, discharge orifice E, the whole being mounted
above a conduit B substantially as described with reference to the accompanying
drawing.
