JOHN HENRY JOHNSON of 47 Lincolns Inn Fields in the County of Middlesex
Gentleman "IMPROVEMENTS IN SHIFTING, STOWING, TRIMMING AND COOLING
GRAIN AND APPARATUS TO BE EMPLOYED THEREIN"-a communication to me
from Herman Stubbendorff, a person residing in the City of Montreal, in the
District of Montreal and Province of Quebec, Canada
This Invention has for its object to enable the operations of shifting grain in
bulk from one receptacle to another in a warehouse or of stowing the same in the
holds of ships or barges, or in railway trucks and of trimming it in position in
either case, to be performed without the necessity of shovelling it, and at the same
time to thoroughly cool the grain during such operation.
According to the said Invention the grain is received into a hopper or vessel
placed intermediately between the point of discharge and the point of delivery and
the said grain is impelled in the direction desired through a pipe, by means of a
blast of air brought into contact with the descending column of such grain at an
angle to its course.
This it is proposed to effect in the case of stowing and trimming grain in bulk
being loaded into a ship or barge by the apparatus now to be described :-
A hopper is placed in such a position on the vessel that the spout from the
elevator, warehouse, or other store will deliver into it discharge pipes from the
lower side or sides of the hopper or receiver, conduct the grain to the chamber in
which it is to be stowed, the said pipes having at their lower ends blast nozzles
or pipes. The discharge pipes can turn in each other and are made telescopic,
thereby allowing the hopper, when a steam ship is being loaded, to be placed on
the main or upper deck, while the grain is delivered into the hold.
To the last joint of the telescopic discharge pipe or pipes are attached blast
nozzles communicating by flexible pipes with any suitable blower placed where
found most convenient and worked from the machinery of the vessel or by separate
mechanism. The connection between the discharge and blast pipes is readily
hough not necessarily made, by a chamber formed on the upper side of the nozzle
[Price 211

page_text: It is
and fitting into a cap formed on the lower end of the discharge pipe so as to amoru
a joint which is practically air-tight and yet allows the relative angles of the
discharge pipe and blast nozzle to be varied at will. The grain to be stowed in
the hold is fed by any suitable mechanism into the hopper, thence passing down
through the pipes till it comes in contact with the blast which drives it forcibly
through the nozzles and delivers it at the desired spot, the air mingling with the
several particles or grains during their delivery effectually cooling the same.
obvious that, as the discharge pipes turn in each other the nozzles can be made
to discharge at any angle to the longitudinal axis of the ship, and that as the
connection between the discharge pipes and nozzles allows the latter to be tilted or
depressed within a considerable range the grain can be deposited at any point or
height desired-The invention may be employed simply in trimming grain stowed
in any receptacle either afloat or ashore, or the grain in any warehouse may be
passed from one floor to another through the said apparatus simply for the purpose
of cooling it or the apparatus can be used when the grain is to be shifted from one
position to another on the same floor the grain being fed into the hopper in any
way and discharged at the desired point as above described.
