Year: 1896

page_text: This Print is in accordance with the Original Specification as it stands after Amend-
ment (under Section 11 of the Patents, &c., Act, 1883) as required by the
decision of the Law Officer of the 6th day of July 1898.
We, GEORGE JONES, Shipbuilder, and ARCHIBALD MCGLASIAN, Naval Architect,
both of West Hartlepool, in the County of Durham, do hereby declare the nature
of this invention to be as follows:-
This invention relates to the construction and arrangement of certain parts of
the hulls of cargo steamships whereby a high working platform is provided and
all openings in or about the deck are placed at a higher level above the load water
liue,
By our improvements better provision is made for stowage and trimming of bulk
cargoes and with less danger of the shifting of such cargoes. Other advantages
incidental to our improvements will be noticed in describing the nature of our
invention which consists as follows:-
A portion of the weather deck at each side of the hatchways is made to slope
upwards at a suitable angle; and a further portion is carried upright to form high
hatch coamings about level with the poop, bridge and forecastle decks, or other suit-
able height. The hatchway openings are contracted in width by horizontal plates
fitted along the top of the said high coamings for the purpose of strengthening them
and to serve as a gangway for getting safely fore and aft. The hatchway open-
ings are also contracted in length by platforms fitted on top of the said high hatch
coamings and extending across them in the vicinity of the masts or at other suit-
able parts for supporting and working the steam winches and other deck apparatus.
These contracted hatchway openings are surrounded by a suitable margin of bulb
angle or other section and fitted with portable cross beams, fore and aft hatch
rests, hatches, cleats and the like accessories. In connection with the said high
hatch coamings, poop, bridge and forecastle, decks are fitted differing from ordinary
poops, bridges and forecastles in having their ends at the side portions tapered
against the sloping deck and high coamings so that an obtuse angle is presented to
Beas striking against them and the shocks which might result are greatly reduced
and also the lodgement of water on the decks is prevented.
In applying this invention the poop may be left off and the high hatch forma-
tion carried aft to the stern of the vessel with a platform or deck on top over a
suitable length, or the forecastle may be left off and the high hatch formation
carried forward to the bows of the ship with a platform or deck over a suitable
length.
The formation of the said upward sloping portion of deck and high hatch coam-
ings is fitted to vessels of any ordinary cross section having either an approximately
square form of gunwale, or a rounded form of gunwale. The said high hatch coam-

page_text: ings are stiffened at intervals preferably corresponding with the frames of the
ship or at other suitable intervals, either by bending up short deck beams or other
stiffeners, and prefer to make the high hatch coamings of such
strength that they do not require hold pillars to support them in
way of the hatch openings, and so avoid obstruction to the working of
cargo at the sides of the hatch openings. Strong deck beams are carried across
the ship at intervals clear of the hatch openings. And at convenient places clear
of the hatch openings tunnels or passage ways are carried transversely through the
high hatch coamings above the weather deck and under the winch or other plat-
forms, with deck plating and bulkheads so arranged as to strengthen the upper
works of the ship and provide means for getting easily from side to side of the ship
on the weather deck and also to aid in freeing the deck of water.
We also fit a projecting ledge of strong bulb angle or other suitable section
along the sides of the high hatch coamings at the most convenient height for sup-
porting cargo gangways, and to act as breakwaters against seas rebounding from
the deck and prevent them mounting up over the hatches.

We, GEORGE JONES, Shipbuilder, and ARCHIBALD MCGLASHIAN, Naval Architect,
both of West Hartlepool, in the County of Durham, do hereby declare the nature
of this invention and in what manner the same is to bo performed, to be particularly
described and ascertained in and by the following statement:-
This invention relates to the construction and arrangement of certain parts of the
hulls of cargo steam ships whereby a high working platform is provided and all
openings in or about the deck are placed at a higher level above the load water
line. By our improvements better provision is made for the stowage and trim-
ming of bulk cargoes and with less danger of the shifting of such cargoes. Other
advantages incidental to our improvements will be noticed in describing our inven-
tion which consists in the construction, combination and arrangement of parts
substantially as hereinafter described and illustrated in and by the accompanying
drawings in which similar letters of reference indicate the like parts in all the
figures.
Fig. 1 is a transverse vertical section of a vessel constructed on the lines of our
invention Fig. 2 is a longitudinal elevation, and Fig. 3 a deck plan of such a
cargo steamer but drawn to a small scale relatively to Fig. 1.
According to our invention the weather deck A at each side of the hatchways
is carried up in the form of a super-structure extending before and abuft the main-
bridge by being set to slope upwards at a suitable angle as at B from which it is
carried up in the form of vertical walls as at C, so as to form high hatch coamings
about level with the poop bridge and forecastle decks or other convenient or suit-
able height. The hatchway openings are contracted in width by horizontal plates D,
fitted along the top of the said high coamings for the purpose of strengthening
them and to serve as a gangway for getting safely fore and aft. The hatchway
openings are also contracted in length by platforms or central bridges as shown

page_text: at E fitted on the top of the said high hatch coamings and extending across them
in the vicinity of the masts or at other suitable parts for binding the sides together
and for supporting and working the steam winches and other deck apparatus.
These contracted hatchway openings are surrounded by a suitable margin of bulb F
or other section and fitted with portable cross beams, fore and afters, hatch rests,
hatches cleats and the like accessories. In connection with the extended bridge
structure and high hatch coamings, a poop G, bridge H and forecastle I are fitted
so as to preserve the advantages of these erections in working the ship but differ-
ing from ordinary bridges, poops and forecastles by having their ends J at the side
portions tapered or set anglewise against the sloping decks B and vertical walls or
high coamings C, of the extended bridge so that an obtuse angle is presented to
seas striking against them, by which the shocks which might result are reduced
to a minimum and the lodgement of water on the decks is provented. The high
working platform provided by the aforesaid construction is protected by the rails K
carried all round. Where the poop and forecastle can be conveniently dispensed
with the extended bridge structure is carried aft to the stern or forward to the bows
of the vessel as the case may be with a platform or deck on the top over a suitable
length forming a deck house in either case when required. The said extended
bridge structure is fitted to vessels of any ordinary cross section, having an approxi-
mately square form of gunwale as shewn at L, Fig. 1, or of a rounded form as
shown at M, Fig. 1. The walls of the structure are stiffened at intervals corres-
ponding with the frames of the ship, or at other suitable intervals, either by
bending up the short deck beams N, Fig. 1, or other stiffeners, and we prefer to
make the walls of the structure of such strength that they require no beam pillars
to support them in way of the hatch openings, and so avoid obstruction to the
working of cargo at the sides of the hatch openings. Strong deck beams are
carried across the ship at intervals clear of the hatch openings as shown by ticked
lines O, Fig. 1, on which deck plating may be fitted at option when required for
strength; and at convenient places clear of the hatch way openings, transverse
tunnels or passageways 1', Figs. 2 and 3, are formed through the extended bridge
structure. These are formed above the weather deck and under the winch or other
centre bridges with deck plating and bulkheads, in order to strengthen the super-
structure and provide a way for getting easily from side to side of the ship on the
weather deck, and also to aid in freeing the decks of water.
We also fit a pro-
jecting ledge Q, Fig. 1, of strong bulb angle or other suitable section along the
vertical walls of the extended bridge structure at the most convenient height for
supporting cargo gangways, and effective position to act as a breakwater against
seas rebounding from the deck and prevent them rising up over the platforms.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed we would have it understood
that we do not claim as of our present invention the building of a vessel with an
extension or extensions of the hold or cargo-carrying space above the level of the
weather-deck, and we are aware that it has been previously proposed in such
vessels to continue the weather-deck upwards so as to form the sides of such super-
structure, and we do not claim such construction generally, but we confine our-
selves to the particular configuration shown in Figure 1, and we declare that what
we claim is:-
1. As an improvement in cargo vessels the formation of a superstructure as described
and illustrated in which a portion of the weather deck at each side of the hatch-
ways is made to slope upward as at B and is then carried up vertically as at C
whereby a high working platform is provided and all openings in and about the
deck are placed at a higher level above the water line, all arranged and adapted
for the purpose substantially as hereinbefore described with reference to the
accompanying drawings.
2. The formation and use in extended bridge structures of the kind herein before

page_text: specified of tunnels or passageways from side to side, substantially as hereinbefore
described and illustrated in the accompanying drawings.
3. A cargo vessel with a combination of structural arrangements, substantially
as hereinbefore described and illustrated in the accompanying drawings and
effecting the purposes above specified.
