PROVISIONAL SPECIFICATION.
Improvements in or relating to Ships' Ventilators.
I THOMAS UTLEY 5 Woburn Hill, Stoneycroft, Liverpool, in the County of
Lancaster, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to ships ventilators and more especially to ventilators of
the kind or class described in the Specification of prior Letters Patent granted to
me No. 17422 A.D. 1888.
According to my present invention I so construct such ventilators as to make
them particularly adapted for ventilating both bunker or ballast tank and cabin.
My said improved ventilators can however be used for the cabin only. The special
features of my said invention are as follows. I provide a lead from the ventilator
to the bunker or ballast tank preferably from the upper part of the ventilator, and
I provide suitable means for closing this lead when desired.
Such means may
consist of a screw down cap, valve, or cover which is arranged in connection with a
suitable seat for the same. When the bunker or ballast tank is shut off by the cap
or cover, the ventilator then serves the cabin only. Another feature of my present
invention consists in providing a closing down cover in the side of the ship for
masking the entrance to the ventilator. Such cover may be secured in position by
a screw bolt arranged to screw into a metal framing let into the ships side.

COMPLETE SPECIFICATION.
Improvements in or relating to Ships' Ventilators.
I, THOMAS UTLEY, of 5 Woburn Hill, Stoneycroft, Liverpool, in the County
of Lancaster, 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 :—
This invention relates to ships ventilators and more especially to ventilators of
the kind or class described in the Specification of prior Letters Patent granted to
me No. 17422 A.D. 1888.
One feature of my present invention relates to the construction of such ventilators
so as to make them applicable for ventilating both bunker or ballast tank and
cabin. My said improved ventilators can however be used for the cabin only.
Another feature of my present invention relates to the provision of a closing
down cover in the side of the ship for masking or closing the opening or entrance
to the ventilator.
In the accompanying drawings
Figure 1 is a vertical section taken through my improved combined cabin
and bunker or ballast tank ventilator, taken on the line, Figure 2.
Figure 2 is a horizontal section on the line y. y Figure 1.
Figure 3 is a partial front elevation of the said ventilator.
Figure 4 is an elevation of a portion of the ship's side showing the opening or
entrance to the ventilator.
Like letters of reference indicate corresponding parts throughout the drawings.

page_text: A is the body of the ventilator; B, B are the air or valve chambers. I have
shown a ventilator provided with two sets of valves separated by a partition
wall C. D, D are the ventilating doors which are hinged at D', D' and provided
with ordinary retaining screw clamps D³, D' for securing the same in the closed
position. E is a pipe or communication leading from the bunker or ballast tank to
one of the air or valve chambers B whereby the apparatus is made to ventilate the
bunker or ballast-tank as well as the cabin. For shutting off the lead E when
desired as for instance in case the valves get out of order I provide a screw down
cap or cover F which works on a bolt F' or is otherwise suitably arranged so that
it can be screwed down upon a seat F' provided around the valve opening and so to
close that part of the ventilator. When used for ventilating the bunker the
corresponding door D is closed. Upon opening the said door D access is obtained
to the cap or cover F for the purpose of raising and lowering the same.
For masking or closing the opening or entrance to the ventilator when desired, I
provide as follows, that is to say, G is a suitable open metal frame, preferably made
of brass or gun metal to withstand shocks, secured in the ships side G. H is a
water-tight cover or lid which can be fixed by bolts H₁ to the interior of the said
frame G thereby masking or closing the entrance to the ventilator and allowing of
the ventilator being shut off in case of accident to the valves or otherwise, or in
case the side lights which are fixed in the opening A' of the frame be carried away
by heavy seas or otherwise damaged. Where it is desired to ventilate the bunker
or ballast tank only I dispense with the division wall C and provide a closing down
cap for both valves or all the valves if there are more than two sets.
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. A combined ship's cabin and bunker or ballast-tank ventilator having a screw
down cap or cover for closing the lead to the bunker or ballast tank, substantially
as described, for the purpose specified.
2. A ship's cabin or bunker ventilator provided with a water-tight cover or lid
for closing the opening or entrance to the ventilator through the ship's side,
substantially as, and for the purpose, specified.
3. The combination, with a bunker or ballast-tank ventilator, of screw down caps
or covers for closing the valve openings, substantially as described.
4. The ship's ventilator constructed substantially as described with reference to
the drawings, and operating as, and for the purpose specified.
