PROVISIONAL SPECIFICATION.
An Improved Lid and Frame for Bunkers.
I, FRED WOOLLONS, of 70, Havelock Street, Hessle Road, Hull, in the County
of York, Manager, do hereby declare the nature of this invention to be as
follows:-
This invention relates to bunkers and effects improvements in respect of the
mode of fitting the lid into the frame.
As at present constructed with hook lugs on the lid, locking into undercuts
in the frame or seat to secure the lid in position, it is found in practice that the
lid can be, and is, often dropped into position without being secured, with the
result that the least concussion forces the lid out, leaving the bunkers open, and
proving a source of great danger to the ship, life and limb. Further, the
locking arrangement at present in use is not absolutely secure and the lids are
known to work round on their seats when the vessels are pitching and tossing
until the lugs are brought opposite to the ports or slips of the undercut and
the lid flies off with the result as above described.
The object of this invention is to provide a bunker lid and frame suitable
for all classes of vessels and so constructed that when the lid is in position the
interlocking is secure and free from all movement and furthermore that the lid
cannot be brought to its seat at all except by being so interlocked.
In carrying out my invention I provide the lid proper with a cylindrical
extension fitting into the frame and secure these two parts together by a screw
thread which may be round, square or V-shaped. Any suitable means are pro-
vided for handling the lid such as hand bars extending across concave recesses.
Fulcrum holes are also provided if required to enable the lid to turn in its
seat by toggle bars or keys.
An Improved Lid and Frame for Bunkers.
I, FRED WOOLLONS, of 70, Havelock Street, Hessle Road, Hull, in the County
of York, 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: —
This invention relates to bunkers and effects improvements in respect of the

page_text: mode of fitting the lid into the frame with a view of obviating the great danger
of shipping water into the bunkers when the bunker lids happen to come off.
As at present constructed with hook lugs on the lid, locking into undercuts
in the frame or seat to secure the lid in position, it is found in practice that the
lid can be and is often dropped into position without being secured, with the
result that the least concussion forces the lid out, leaving the bunkers open, and
proving a source of great danger to the ship, life and limb. Further, the
aforesaid locking arrangement even when properly fastened is not absolutely
secure and the lids are known to work round on their seats when the vessel is
pitching and tossing until the lugs are brought opposite to the ports or slips
of the undercut and the lid flies off with the result as above described.
The object of this invention is to provide a bunker lid and frame suitable
for all classes of vessels and so constructed that when the lid is in position the
interlocking is secure and free from all movement and furthermore that the lid
cannot be brought to its seat at all except by being so interlocked? ··

And in order that my invention may be clearly understood and readily carried
into effect, I will proceed to describe the same with reference to the accompany-
ing drawing in which Fig. 1 is a sectional view taken on line of Fig. 2,
which is a corresponding plan view of a bunker lid and frame constructed
according to this invention.

In the drawing, a is the frame and 6 the lid proper which I provide with a
cylindrical extension e fitting into the frame and secure these two parts together,
by a screw thread d which may be round as shown, square or V shaped. It will
now be seen from the foregoing description that the lid a is brought to its seat
by being screwed into the frame b and cannot be suddenly, forced therefrom but
can only be withdrawn by the ordinary process of unscrewing. Any suitable
means are provided for handling the lid such as hand bars e extending across
concave recesses f. Fulcrum holes are also provided if required to enable
the lid to be turned in its seat by toggle bars or a key. If desired the space h
formed between the underside of the lid and the bottom flange of the frame
may be provided for the reception of an air grate.
قد:
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: -
The improved lid and frame for bunkers in which by means of a cylindrical-
extension formed on the lid and fitting into the frame the lid and frame are
interlocked together by a screw thread substantially as, described with reference
to the accompanying drawing and operating as and for the purpose as herein-
before specified.
