PROVISIONAL SPECIFICATION.
Improvements in Ventilators.
I, WILLIAM THOMAS SUGG, of Regency Street, in the City of Westminster,
Engineer, do hereby declare the nature of this invention to be as follows:-
The object of this invention is to improve the ventilating apparatus for use in
ships, for which I obtained Letters Patent dated 5th June 1891, No. 9563, in
which a vacuum is produced in the ventilator, which tends to raise a valve off
its seat, to effect the ventilation of the cabins or deck below, the valve being
arranged so that it will close, should water enter the ventilator.
It has been found, however, that the valve cannot be made sufficiently tight to
prevent the entrance of water to the ventilating shaft, and the present improve-
ments are designed to overcome this difficulty.
In carrying out this invention, I provide, below the tubular openings, a conical
deflector, which will conduct any water that may enter the openings into a suitably
placed tray, which will be of greater diameter or size than the shaft.
This tray will be supported by struts, which may be tubular, to conduct the water
caught by the tray outside the ventilator, or other means may be provided for this
purpose.
The tray may also carry, on its underside, the rod or stem on which the valve
works.
Dated this 24th day of February 1897.

I, WILLIAM THOMAS SUGG, of Regency Street, in the City of Westminster,
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 this invention is to improve the ventilating apparatus, or cowls,
in which a vacuum is produced in the cowl by the passage of a current of air
across a series of openings in the top plate or cover of the cowl, the said current
being directed by a straight deflector situated above, and parallel with, the cover,
the improvements being directed especially to prevent water passing down the
shaft with which the cowl is connected.
In the accompanying drawing I have shewn, in sectional elevation, the improved
cowl as adapted to the roof of a cabin or other compartment.
[Price 8d.1

page_text: A will be the roof of the compartment, and B the ventilating shaft, the inlet
to which is closed by a hit-and-miss valve C.
To the head of the shaft B I adapt a chamber B', preferably of globular shape,
which is closed by a flat top or cover, in which the openings are made, and which
may consist of suction tubes B2, inserted in the top or cover, with the deflector D
above, and parallel with, the cover.
In carrying out this invention, I provide, below the openings B12, a conical
deflector E, which will conduct any water that may enter the openings B2 into a
tray G, which will be of greater diameter or size than the shaft B, and will be
placed above it, at any convenient distance.
This tray will be supported by struts H, which may be tubular, to conduct any
water that may be caught by the tray outside the cowl B; or other means may be
provided for this purpose.
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. The combination with a suction cowl of the character described, of a conical
deflector and a tray provided with means for conducting water to the outside of the
cowl, as set forth."
2. The improved ventilating apparatus as herein shewn and described.
