COMPLETE SPECIFICATION.
A New or Improved Collapsable Shoot or Feeder for Double Decked
Ships Carrying a Cargo of Grain.
I, GEORGE JACKSON HAY of 4, St. Mary Axe London, Shipowner do hereby
declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement :-
My invention relates to a new or improved collapsable and extensible shoot
or feeder for double decked ships carrying a cargo of grain in bulk and has for its
object to enable such ships to be permanently fitted with means whereby a grain
tight shoot or feeder may be formed at a moments notice between the decks and
around the hatchways of the ship to carry the grain in bulk according to the
regulations of the Board of Trade and with increased safety to life and property
while the accumulative expense incurred at each voyage will be greatly reduced.
According to my invention I dispense with the erection of the temporary
wooden structures hitherto required at each voyage for feeding the grain in to the
hold of the vessel and I substitute for the same a permanent collapsable and
extensible shoot or feeder.
In the accompanying drawings in which like letters of reference indicate
corresponding parts
Figure 1. is a plan of my improved shoot or feeder collapsed on the lower deck
of a double decked ship.
Figure 2 is a section on line x x of Figure 1. of a part of a double decked ship
provided with my improved shoot or feeder erected in position.
Figure 3 is a top view of the fore or aft flap erected in position, the flooring of
the deck being removed.
H is the hatchway and C C¹ are the coamings D is the upper deck and D¹ the
lower deck upon which are secured by hinges h the two fore and aft flaps a
and the two athwart flaps a' having the shape shewn in Figure 1 and made of iron or
other plates strengthened by the transverse bars b-these four flaps thus arranged
around the hatchway H abut at the corners when raised in an erect position
as shewn in Figure 2 and form a shoot or feeder from the hatchway in the upper
and lower decks D and D¹ to the hold of the vessel enclosing the hatchway
from deck to deck, the shape of the flaps causing them to incline towards the
hatchway in the lower deck D' as shewn in Figure 2 so as to form a funnel shaped
shoot or feeder for the hold of the vessel.
The flaps a are notched at their upper or outer edges (Fig. 3) to allow them to
pass the transverse beams m supporting the flooring of the upper deck D and
to close against the inner side of the latter when raised up to form a shoot
or feeder as before described-these flaps a are each secured in position by a bolt d
passing through openings formed for this purpose in the beams m behind the flaps a.
The flaps a¹ are made to close against the transverse beam in front of them, being
secured thereto by means of bolts and nuts. In case there was not transverse beam
immediately in front of these flaps, a false beam or an angle iron may be provided
for this purpose.
The corners of the flaps which abut edge to edge when erected are secured
by the removeable perforated angle irons i (Figs. 2 and 3) arranged at the back
and along the edges of each flap in such a manner as to have their two opposite
flanges tightly secured together by bolts and nuts. These flaps can be raised by
hand or by means of pulleys fixed conveniently to the under side of the upper
deck. When no further required for use, the angle irons i and the bolts d'are

page_text: removed and the flaps are collapsed and allowed to lay flat on the lower deck as
shewn in Fig. 1.
Having now fully described and ascertained the nature of my said inven™
tion and in what manner the same is to be performed I declare that what
I claim is.
In double decked ships or vessels the arrangement of a collapsable shoot or
feeder for grain cargo in bulk consisting of fore and aft flaps and of two athwart
flaps all hinged to the lower deck and secured in their extended position
substantially as herein described and shewn and for the purpose set forth.
Dated this 2nd day of November 1892.
