PROVISIONAL SPECIFICATION.
An Improved Shoot or Feeder for Double Decked Ships Carrying a
Cargo of Grain.
I, GEORGE JACKSON HAY of 23 Kensington Court Mansions London, Ship-
owner do hereby declare the nature of this invention to be as follows:-
This invention has reference to improvements in former Letters Patent granted
to me the 4th day of November 1892 and numbered 19867, in which double decked
ships are permanently fitted with incans, 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.
The said shoot or feeder being formed of two fore and aft flaps and two athwart
flaps. secured by hinges to the lower deck, these flaps arranged around the batch-
way abut at the corners when raised in an erect position and form a shoot or 'feeder
from the hatchways on the upper and lower decks to the hold of the vessel, and
when the shoot or feeder is no further required for use the flaps are collapsed and
allowed to lie flat on the lower deck.
According to this my present invention the flaps forming the shoot or feeder are
hinged to the underside of the upper deck instead of to the lower deck as described
in my above mentioned former Patent. When the flaps are not required for
forming a shoot or feeder they are raised up and rest against the beams of the
upper deck, being secured in their raised position by any suitable catch.
The flaps when in position for forming the shoot or feedor may be either
perpendicular or oblique according to circumstances, and in order to effect this the
width of the flaps in relation to their length, is reduced, the spaces between the
transverse beams of the upper deck being filled in with plate iron, or other
material to the required length of the flaps, and to the level of the underside of such
beams.
The side flaps are hinged to the upper deck or to the said filling in plates, and
the end flaps to the existing transverse beams or to false beams or angle irons fitted
for the purpose, the lower edges of the flaps being secured to the coamings of the
lower hatch by nuts and bolts.
The corners of the flaps which abut edge to edge when lowered to form the shoot
or feeder are secured by removable perforated angle irons arranged along the edges
of each flap in such a manner as to have their two opposite flanges tightly secured
together by bolts and nuts.

COMPLETE SPECIFICATION.
An Improved Shoot or Feeder for Double Decked Ships Carrying a
Cargo of Grain.
I, GEORGE JACKSON HAY, of 23, Kensington Court Mansions, Loudon, Ship-
owner, 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 :-
This invention has reference to improvements on former Letters Patent granted

page_text: to me on the 4th day of November 1892 and numbered 19867, in which ships are to
be permanently fitted with means whereby grain-tight shoots or feeders may be
fitted between the decks and around the hatchways or openings in the decks to
allow them to safely carry grain in bulk under the "Carriage of Grain" Act, and
according to regulations and requirements of the Board of Trade.
The said shoot or feeder being formed of two fore and aft flaps and two end or
athwart flaps secured by hinges to the lower decks, these flaps arranged around the
hatchways or openings abut at the corners when in an erect or oblique position, and
form a shoot or feeder to the holds of the vessel, and when the shoot or feeder is no
longer required for use the flaps are collapsed and allowed to lie flat on the lower
decks.
According to this my present invention, the flaps for forming the shoot or feeder
are permanently hinged to the under parts of the hatchway coamings, or the beams
or other parts existing in the ordinary construction of vessels, or to permanent
fittings of iron or other material specially provided for the purpose as may be
necessitated by the position or shape of the intended shoot or feeder, and so that
the shoot or feeder in whatever position and shape it may be formed shall be hinged
at the top of the flaps and be grain-tight; instead of being hinged on any lower
deck as described in my above mentioned former Patent.
When the flaps are not required to be down for forming a shoot or feeder, they are
raised or opened up to the beams of any deck above and secured in their raised position
by means of catches or hooks of iron or steel attached to the beams and hanging at
such an angle that they will close under the edges and ends of the flaps and be
kept there by the weight of the flaps resting on them, and the ends of the hooks or
catches may be additionally kopt in position to retain the flaps against the beams
by being bolted to the flaps by removable screw bolts and nuts.
A shoot or feeder under this invention may be arranged to have either perpen-
dicular ends and sides or be funnel shaped with oblique ends and sides when the
flaps are lowered down into position to form a shoot or feeder, and in order to effect
this difference in shape the ends of the flaps will be of the angle necessary to form
the shape required so that the flaps abuit at the corners, the flaps also being hinged
in the position necessary to form the shape of shoot or feeder required.
The ends of the end or athwart flaps are to be turned over or flanged a few
inches to or at a right angle to the face so that they will overlap the side or fore and
aft flaps when all the flaps are down to form a shoot or feeder.
When the flaps are down to form a shoot or feeder they are to be bolted
together at the corners where they overlap, and at the overlap where they may be
divided in length for convenience with removable screw bolts and nuts at such
distance apart, and the bolts and nuts of such dimensions as the width and weight
of the flaps and the size of shoot or feeder may require for the shoot or feeder to
be strong, rigid, and grain-tight.
The lower edges of the Haps being also firmly secured in position when down
(and a shoot or feeder is to be formed) by removable bolts and nuts, to the lower
hatchway coauiings, or angle irons or specially provided fittings necessitated by
the varied construction of vessels and position of feeder.
If the ends of the end flaps are not flanged as described, the four corners of
the shoot or feeder are to be fastened together with angle irons and bolts and nuts
as described in my former Patent No. 19867.
As a modification of my invention the flaps forming the shoot or feeder may
be divided in length for convenience, and in such cases there will be an overlap
of a few inches where so divided; they are to be constructed of plain or corru-
gated plate iron or steel or other material; they are to be stiffened or strengthened
at intervals at right angles to their length; according to the thickness of plating
or other material used and the dimensions.
A hinged door or hatch may be fitted in one or both of the end or athwart flaps
for convenience in the loading and unloading, and for convenience in bolting

page_text: together the flaps, such hatch or door being provided with any ordinary means of
securing it so as to be grain-tight.
In order that my invention may be more fully understood, I will now proceed to
describe same with reference to the accompanying drawings in which like letters of
reference indicate corresponding parts throughout the figures.
Fig. 1 is a diagrammatic perspective view showing the means I employ whereby
double decked vessels may be at once fitted with grain-tight shoots or feeders,
Fig. 2. is an underside view of a hatchway and part of a deck fitted with the means
for forming a grain-tight shoot or feeder, Fig. 3 is a similar view of a slightly
modified form, Fig. 4 is a section through the hatchways of a vessel viewed from
side to side of the vessel fitted with my improved grain-tight shoot or feeder, and
Fig. 5 is a section viewed fore or aft through a similar vessel.
According to my invention and with reference to Fig. 2 of the accompanying
drawings, I permanently hinge to the under part of the hatchway coamings d' of the
deck, two athwart or end flaps a, b, and two side flaps c, d, which when not required
for use are drawn up to the under surface of the above deck and held in that
position by means of hooks or catches g which are fitted to the transverse beams or
planks of the deck, or to false beams provided for that purpose.
The two athwart or end flaps are furnished with flanges while the lower edges
of each flap are provided with bolt holes 6 by means of which they may be secured
by bolts to the hatchway coamings of the lower deck, or to other fittings when
no deck or coamings exist when required to form a grain-tight shoot or feeder, as
shown in Fig. 5. of the accompanying drawings.
The flaps a b c d are formed of iron plates of suitable thickness according to the
size of the shoot or feeder to be formed, and fitted with transverse stiffening angle
irous or butt straps or of corrugated iron plates or other material of the
required dimensions.
The flaps may be rectangular in shape as shown in Fig. 1. and when brought
into the position shown in Fig. 5 are secured at the corners by bolts m with the
aid of the flanges f.
In Fig. 3 the flaps at are oblique or slanting, and all flaps are hinged at a
short distance from the hatchway coamings, to the transverse beams or planks of
the deck above or to false beams or other fittings for that purpose, so that when
brought into the position shown at S (Fig. 4) they will form a funnel shaped shoot
or feeder, said flaps being furnished with flanges and bolt holes in order that they
may be secured in position in a similar manner to those described and shown
with reference to Fig. 2 of the accompanying drawings.
In cases where the flaps are required to be of large size they may be formed in
two or more parts and bolted together as shown at g Fig. 4.
Having now particularly 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:-
(1.) In vessels for carrying grain in bulk, the arrangement of a collapsible shoot
or feeder, consisting of two athwart flaps and two side flaps, all hinged underneath
any deck to open up and be secured in their extended position substantially as
herein described and shown and for the purpose set forth.
(2.) The improved shoot or feeder for vessels carrying grain in bulk constructed
arranged and operating substantially as herein described and shown.
Dated this 6th day of December 1893.
