Improvements in the Construction of Cargo-carrying Steamers.
I, EMIL HUGO OSCAR ROBERT ROPNER, the younger, of Stockton-on-Tees,
in the County of Durham, Shipbuilder, do hereby declare the nature of this
invention to be as follows:-
--
My invention has reference to an improved construction of cargo carrying
steamers, according to which a hull made with sides of any desired contour, a
bottom, which may be flat or have rise of floor curves or rounded parts connecting
the sides to the bottom a weather deck and curved or rounded parts connecting
same with the said sides is combined with weather deck beams constructed with
upwardly extending parts of any desired height to which plating is so applied as
to form an upward extension or extensions of the hold or holds or main cargo space
or spaces. The said weather deck beams may be each in one piece, of any suitable
cross section or sections, they may be of different sections in different parts of their
length according to position and stress, they may be strengthened at the corners
or bends by gusset plates or other strengthening devices; or they may be made in
parts connected together by fish plates, as for example in two parts with central
joint; there may be any required camber and any desired number of hatchways, as
wide as or narrower than and surrounded or not by the peculiarly constructed
extension of the main cargo space or spaces as already referred to.
Dated this 1st day of June 1895.

Improvements in the Construction of Cargo-carrying Steamers.
1, EMIL HUGO OSCAR ROBERT ROPNER, the younger, of Stockton-on-Tees, in
the County of Durham, Shipbuilder, 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 has reference to an improved construction of cargo carrying
steamers, according to which a hull made with sides of any desired contour, a
bottom, which may be flat or have rise of floor, curved or rounded parts connecting
the sides to the bottom, a weather deck and curved or rounded parts connecting
same with the said sides is combined with weather deck beams constructed with
upwardly extending parts of any desired height to which plating is so applied as to
form an upward extension or extensions of the hold or holds or main cargo space
or spaces. The said weather deck beams may be each in one piece, of any suitable
cross section or sections, they may be of different sections in differents parts of
their length according to position and stress, they may be strengthened at the
corners or bends by gusset plates or other strengthening devices; or they may
be made in parts connected together by fish plates, as for example in two parts

of hatchways, as wide as or narrower than and surrounded or not by the peculiarly
constructed extension of the main cargo space or spaces as already referred to.
In the accompanying drawings, Fig. 1 is a part transverse section and Fig. 2
a part central longitudinal section of a vessel constructed according to this
invention.
The frames 1 of the vessel are formed with curved or rounded parts A where
they are connected with the bottom 2 of the vessel and with curved or rounded
upper parts B. The weather deck beams are formed with approximately hori-
zontal end parts 3 and with a raised central part 4, horizontal or approximately
so, said end and central parts being connected by upwardly extending parts 5,
which, in the example, are vertical. Strengthening gusset plates may be fitted
at the corners 6 and 7; the beam may be divided by a scarph joint if desired.
Although the frames shown are of bulb angle they may be of other section, for
instance, frame and reverse frame. 8, 9, 10, 11, 12 and 13 are ordinary shell
plates applied to the frames 1 and 14, 15, 16 and 17 are plates of only deck-plate
thickness applied to the weather deck beams, except where hatchways 18 are
required. Rails 19 are provided along the gunwale of the vessel but, if desired,
bulwarks of the ordinary kind may be employed.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
1 claim is :-
:
In a cargo carrying vessel of the kind in which there is additional cargo carrying
space above and in free communication with the hold and in which the frames 1 of
the hull have curved or rounded parts A. B the combination with the said frames
of weather deck beams constructed with upwardly extending parts to which
plating of weather deck thickness is so applied as to form the required upward
extension or extensions of the hold or holds or main cargo space or spaces
substantially as described with reference to and shown in the accompanying
drawings.
