PROVISIONAL SPECIFICATION.
An Improved Scupper Channel or Gutter for Drawing Off Water
from Ships' Decks.
I, WILLIAM COLLINSON, of St. John's Terrace, Middlesbrough-on-Tees, in
the County of York, Shipyard Manager, do bereby declare the nature of this
invention to be as follows:-
My invention relates to the construction of scuppers, channels or gutters for
drawing off water from ships' decks, the object in view being to effect this purpose
without cutting away the gunwale bar for each scupper channel or gutter provided,
according to the existing mode of constructing these outlets, which cutting away of
the gunwale bar has to be compensated by additional plating rivetted or welded
round the opening or weakened part, which my invention dispenses with.
Furthermore, by my improved construction of scupper or channel, instead of
weakening the gunwale bar by cutting it away I provide a box shaped or hollow
frame which serves as a stiffener in the form of a knee piece to the gunwale bar
whilst leaving the gunwale bar intact.
away
In carrying out my invention instead of cutting the gunwale bar I leave
this intact and cut a hole through the stringer and a corresponding hole through
the shell at underside of deck and in each case clear of the gunwale bar, I then
provide a channel or gutter connecting the two holes together, the channel or
gutter being in the form of a trough furnished with flanges, which flanges serve as
compensating plates round the holes cut through the stringer aud shell and in a
manner which materially strengthens the gunwale bar at the part where it was
weakened before.

An Improved Scupper Channel or Gutter for Drawing Off Water
from Ships' Decks.
1, WILLIAM COLLINSON, of St. John's Terrace, Middlesbrough-on-Tees, in
the County of York, Shipyard Manager, 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 the construction of scupper channels or gutters for
drawing off water from ships' decks, the object in view being to effect this purpose
without cutting away
the gunwale bar for each scupper channel or gutter provided
according to the existing mode of constructing these outlets, which cutting away
of the gunwale bar has to be compensated for by additional plating rivetted or
welded round the opening or weakened part which my invention dispenses with.
Furthermore by my improved construction of scupper or channel instead of

page_text: weakening the gunwale bar by cutting it away I provide a box shaped or hollow
frame which serves as a stiffener in the form of a knee piece to the gunwale bar
whilst leaving the gunwale bar intact.
And in order that my invention may be clearly understood and readily carried
into effect, I will now proceed to describe the same with reference to the drawing
hereto annexed, in which Figure 1 illustrates a sectional view of a scupper channel
constructed and fixed in position according to my invention; Figure 2 is a plan
view corresponding thereto, and Figure 3 is a transverse sectional view taken on
line of Figure 1.
In the drawing a is the gunwale bar which instead of being cut away I leave
intact and cut a hole 6 through the stringer c and a corresponding hole d through
the shell eat underside of deck and in each case clear of the gunwale bar a.
I then provide a channel or gutter connecting the two holes b and d together, the
channel or gutter being in the form of a trough furnished with flanges f¹ƒ³ which
flanges serve as compensating plates round the holes cut through the stringer and
shell, and in a manner which materially strengthens the gunwale bar at the part
where it was weakened before.
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:-
In the construction of scupper channels or gutters for drawing off water from
ships' decks, the employment of a trough communicating with holes cut in the
stringer and shell of the ship, which trough is furnished with flanges which serve
as compensating plates to the said holes and acting as a stiffener to the gunwale
bar whilst leaving the gunwale bar intact, substantially as hereinbefore described
and-illustrated in the accompanying drawing.
