or Pulverulent Substances in a Dry State.
:
I, JOHN CLAYTON MEWBURN of 169 Fleet Street in the City of London, Fellow
of the Institute of Patent Agents do hereby declare the nature of my invention
for NOVEL MEANS OR APPARATUS FOR LOADING OR UNLOADING GRANULAR OR
PULVERULENT SUBSTANCES IN A DRY STATE to be as follows:-
This invention has reference to the loading or unloading of granular or
pulverulent substances in a dry state in to or from ships, barges; trucks or
other receptacles. The improved apparatus for this purpose is composed of four
main parts namely a suction and force or blast apparatus, an air pressure relator,
a pipe for conveying the substances, and a weighing and registering distribútor.
The invention is based on the employment of a suction and force apparatus of the
type employed in blast or similar furnaces, and on the utilization of the blast
produced by this apparatus to force the granular or pulverulent substances into
and through a pipe which conveys them from the vessel or receptacle from which
they are to be unloaded to the warehouse or other required place, or vice versâ:
The air from the suction and force apparatus passes into the air pressure regulator
which is an airtight metallic cylinder capable of containing a large quantity of air;
the air is stored therein so that a regular and constant pressure is maintained.
From this regulator the air at a constant pressure and relative speed passes into
a pipe of iron, zinc or other suitable material for the purpose of forcing through it
the granular or pulverulent substances that are to be moved from one point to
another. This blast pipe will be vertical, horizontal or inclined according
to circumstances and will follow any required course; it is fitted with' branches
leading off to any desired positions and its bends should not be so abrupt as to
interfere with the passage of the granular or pulverulent substance. At a certain
point or points in the blast pipe it is divided so as to be connected with a
distributor. These distributors are placed in the body of the substance to be
loaded or unloaded and serve to weigh it and to register the weight by means of
a scale and hands and they then pass it on into the blast pipe so that it may, be
driven to the place of deposit. Or the blast pipe may have one or more branch
pipes whose ends are placed in the substance to be loaded or unloaded; the suction
or induced current caused by the blast of air through the blast pipe will draw the
substance through the branch pipes into the blast pipe which will then convey it
to the required place.

I, JOHN CLAYTON MEWBURN of 169 Fleet Street in the City of London Fellow
of. the Institute of Patent Agents. do hereby declare the nature of this invention
(a communication from abroad by Henry Delbaye of 1 Boulevard St Denis Paris,
France, Civil Engineer), and in what manner the same is to be performed, to bo
particularly described and ascertained in and by the following statement:—
This invention has reference to the loading or unloading of granular or
pulverulent substances in a dry state into or from ships, barges, trucks or other
receptacles. The improved apparatus for this purpose is composed of four main
parts, namely a suction and force or blast apparatus, an air pressure regulator,
a pipe for conveying the substances, and a distributor. The invention is based on
the employment of a suction and force apparatus, of the type employed in blast or
similar furnaces, and on, the utilization of the blast produced by this apparatus
to force the granular or pulverulent substances into and through a pipe which
conveys them from the vessel or receptacle from which they are to be unloaded to
the warehouse or other required, place, or vice versa. The air from the suction and
force apparatus passes into the air pressure regulator which is an air tight metallic
cylinder capable of containing, a large quantity of air; the air is stored, therein so
that a regular and constant pressure, is maintained. From.this regulator the air at
a constant pressure and relative speed passes into a pipe of iron, zinc or other
suitable material for the purpose of forcing through it the granular or pulverulent
substances that are to, be moved from one point to another. This blast pipe will
be, vertical, horizontal or inclined according to circumstances and will follow any
required course; it is fitted with branches leading off to any, desired positions and
its, bends should not be so abrupt, as to interfere with the passage of the granular
or pulverulent substance.. At a certain point or points in the blast. pipe it is.
divided so as to be connected with a distributor. These distributors are placed in
the body of the substance to be loaded or unloaded and they pass it on into the
blast pipe, so that it may be driven to the place of deposit. Or the blast pipe may
have one or more, branch pipes whose ends.are placed in the substance to be loaded
or unloaded;, the suction or induced current caused by the blast of air through the
blast pipe will draw the substance through the branch pipes into, the blast pipe
which will then convey it to the required place.
The annexed drawings serve to illustrate the invention,, Figure 1 being a plan
and Figure 2 a section showing the apparatus applied for unloading a vessel or
barge and depositing the substance on the floors of a warehouse. In these
figures A is: a steam or motive cylinder, 6 the piston rod, c the piston and the
steam. inlet ports of same. This cylinder works the piston rod E and piston F of
the blowing cylinder G. kk are the air inlet valves and' h h the, air outlet valves
of the cylinder G. I is an air pipe communicating with the pipe J which leads to
the air pressure regulator R. Qis a pipe leading from, the regulator R to the
vessel or barge. N and thence by branch pipes to the several floors OO of the
warehouse. D D are the distributors placed in the body of the substance in

page_text: the barge N. Figure 3 illustrates a modification in which the blast pipe Q has
several branches x x communicating with the substance to be shifted; each of
these branches may in its turn have sub-branches so that the substance to be
shifted may be acted upon at a number of points. P represents the quay. The
blowing apparatus may be fixed or be movable on rollers or otherwise along the
quay or on the water to any required position.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed as communicated to me
I declare that what I claim is :-
The means or apparatus arranged and operating as hereinbefore described for
loading or unloading granular or pulverulent substances in a dry state.
