A COMBINED HOPPER STEAMER COLLIER AND CARGO STEAMER
Year: 1885

page_text: I, ANDREW BROWN of Renfrew, in the County of Renfrew North Britain
Shipbuilder and Engineer do hereby declare the nature of my invention for
A COMBINED HOPPER STEAMER COLLIER AND CARGO STEAMER to be as follows:-
This combined Hopper Steamer, Collier & Cargo Steamer consists essentially of
a vessel of suitable form & dimensions which I fit with Hopper holds of the usual
descriptions for the purpose of enabling the said vessel to carry sewage or refuse
in addition to the usual hold for carrying coals or other dry cargo. The advan-
tages of a vessel constructed according to my invention are obviously very great,
such as being provided with the means of carrying away sewage or refuse and
depositing same at sea or on land when required & afterwards loading & carrying
coals & cargo when returning to port. A vessel constructed according to my
invention may be made either a collier, a hopper steamer or a Cargo Steamer.'
My invention can be applied to any existing Hopper steamer or Collier or Cargo
steamer by making the necessary modifications & additions.

I, ANDREW BROWN of Renfrew in the county of Renfrew, North Britain, Ship
Builder and Engineer 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:―
The object of my invention is the construction of a vessel which can be used for
the double purpose of conveying sewage or refuse, as well as dry cargo, such as
coals, in the same hull.
My said vessel is made of suitable form and dimensions and is fitted with
hopper holds for carrying the said sewage or refuse, in addition to the usual hold
for coals or other dry cargo.
In the accompanying sheet of drawings, which represent certain modes of carrying
my invention into practice:-
Figure 1 is a sectional longitudinal elevation.
Figure 2 is a plan, and
Figure 3 is a midship section of a steam vessel constructed according to my
invention.
Figures 4, 5 and 6 are respectively midship sections shewing modified forms of
construction.
Similar letters of reference denote similar parts throughout the drawings.
Referring to figures 1, 2 and 3, A A are side hoppers for containing sewage
or refuse and B is the ordinary hold for dry cargo. A' A¹ are the hatchways or
openings leading to the hoppers and B₁ are those leading to the ordinary hold.
CC are longitudinal partitions dividing the hoppers from the hold.
The bopper doors DD are worked by means of the chains E and crabs or
winches F.
In Figure 3 the longitudinal hopper partition is shewn straight on one side and
curved on the other, either form being used as found most convenient.
The curved partition gives more space to the hopper, and the straight partition
more space to the hold.
In the modified mid-ship section shewn in Figure 4 the partitions C C are both
curved and the upper parts of the vessel's sides are curved outwards in order to
give a large proportion of space to the hoppers.
In Figure 5, the arrangement shewn in figures 3 and 4 is reversed, a single
hopper A being placed in the centre and cargo holds B B on each side..
The hopper doors D D are in the bottom of the vessel and the partitions C C are
shewn as vertical, but they are not necessarily confined to such form.
In Figure 6 a further modification is shewn. In this case the hopper A is placed
above the cargo hold B and separated therefrom by a deck H, the hopper doors D D
are in the side of the vessel and a compartment W is provided for water ballast.
The advantages of a vessel constructed according to my invention are obviously
very great as it is enabled to carry away sewage or refuse in the hoppers A A and
after discharging the same at sea or on land, can load for the return voyage with
coals or other cargo.

page_text: In carrying out the invention in practice, the particular arrangement will depend
in some measure upon the nature of the cargo intended to be carried, and I wish it
to be understood that I do not confine myself to the precise details of construction
shewn in the accompanying drawings as such may be modified to suit circumstances
without departing from the essential features of my invention.
A vessel constructed according to my invention may be made either a hopper
steamer, or collier, or a cargo steamer.
My invention may be applied to any existing hopper steamer, collier, or cargo
steamer by making the necessary modifications therein and additions thereto.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim, is:
.
(1.) An improved vessel forming a combined Hopper Steamer, Collier and
Cargo Steamer, constructed substantially in the manner and for the purposes
herein described and shewn.
(2.) The combination with a cargo steamer, of a hopper or hoppers, substantially
in the manner and for the purposes herein described and shewn.
(3.) The combination with a Hopper Steamer, of a cargo hold or holds, substan-
tially in the manner and for the purposes herein described and shewn.
