page_text: I, ALEXANDER THOMSON ORR, Langford House, Holyhead, Superintendent
Engineer, do hereby declare the nature of this invention to be as follows:-
Its object is an arrangement for the prevention of water making its way down
the ventilator shafts of ships.
Fig. 1. Shews an upright section of ventilator and cowl, shewing water-tight
arrangement in ventilating shaft.
Fig. 2. Shews a sectional plan on the line A, B.
Fig. 3. Shews an upright section of ventilator cowl shewing water-tight
arrangement in cowl.
Fig. 4. Shews a sectional plan on the line A, B.
Fig. 5. Shews a sectional plan on the line C, D.
The invention consists in enlarging the upper portion of ventilator shaft,
or cowl, as shewn at E; the insertion of an internal piece F; and also an
internal inverted dish G, of such a size, that the area between the dish G, and
the sides of the ventilator shall be slightly larger than the area of H.
inverted dish G, being larger than the top of the internal piece F.
The
Nozzles or spouts I, are provided to carry off water from space between inner
piece F, and sides of ventilator.
Pieces marked J, are to baffle the air passing out through the nozzles or
spouts I.
K, are supporting pieces for the inverted dish G.
The mode of action is as follows. Any water entering the bell mouth L,
is prevented by the inverted dish G, from entering the inner piece F, and is
deflected by the inverted dish G, to the sides of the ventilator, falling into the
space between inner piece F, and the sides of the ventilator, and is carried off
by spouts I.
The air is free to pass into inner piece F.
Small clack valves may be fitted to the spouts I, to prevent the passing of
air.

page_text: the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
This invention has for its object an arrangement for the prevention of water
making its way, down the ventilating shafts of ships, as shown in drawings left
with the Provisional Specification.
Fig. 1. Shows an upright section of ventilator and cowl showing water-tight
arrangement in ventilating shaft.
Fig. 2. Shows a sectional plan on the line A, B.
Fig. 3. Shows an upright section of ventilator cowl showing water-tight
arrangement in cowl.
Fig. 4. Shows a sectional plan on the line A, B.
Fig. 5. Shows a sectional plan on the line C, D.
The invention consists in enlarging the upper portion of ventilating shaft,
or cowl, as shown at E, the insertion of an internal piece F, and also an
internal inverted dish G, of such a size that the area between the dish G, and
the sides of the ventilator shall be slightly larger than the area of H.
The
inverted dish G being larger than the top of the internal piece F. Holes, with
or without spouts I are provided to carry off water from space, between inner
piece and sides of ventilator.
Pieces marked J, are to baffle the air passing out through the spouts I.
K, are supporting pieces for inverted dish G.
The mode of action of this invention is as follows.
Any water entering the bell mouth L, is prevented by the inverted dish G,
from entering the inner piece F, and is deflected by the inverted dish G, to the
sides of the ventilator, falling into the space between the inner piece F, and
the sides of the ventilator, and is carried off by the spouts I. The air is free
to pass into the inner piece F. Small clack valves may be fitted to the spouts I
to prevent the passing of air, and in the case of ventilators highly situated, where
little water is likely to pass down, the inverted dish G may be removed.
Having now particularly described and ascertained the nature of my invention
and in what manner the same is to be performed, I declare that what I claim
is:-
1. The prevention of water making its way down the ventilators or cowls of
ships.
2. Enlarging the upper portion of ventilator shaft or cowl.
3. The insertion of an internal piece F.
4. The insertion of an inverted dish G.
