page_text: CONNECTION FROM THE BOTTOM, BRASS. CAP UP TO THE MAIN DECK.
The 2 iron or copper or brass pipe is carried from the bottom of the said brass:
cap up to the main deck,, (average length will be about 14 ft.) & screwed onto the
upper end of this pipe, is the deck cap or the indicator proper.
(B.) BRASS INDICATOR PLACED ON THE MAIN DEOK.
The indicator brass casting (B) is screwed onto the 24" pipe & has a flange on it,
to be secured into the deck with screws or bolts. There is sorewed onto the top
of this casting a cover (brass) with a glass " thick and 2º dia. let into the said
Cover.
BRASS WHEEL ON BEARERS IN BRASS INDICATOR (B).
The said brass wheel is constructed' of light brass & rests on a brass bearer on
one side & through the body of the casting (B) on the other, so that the spindle of
the wheel comes sufficiently through to screw on a thumb screw. Immediately
over the wheel, there is placed a brass pointer, which pointer is secured to the inside
of the casting (B) by a screw from the outer side.
TAPE LINE AND COPPER FLOAT.
There is a tape line carried over the brass wheel, one end with a 2 oz. piece of
lead secured to it, & the other end of the tape is secured to the copper float, which
float is 2" dia. x 4" long & has a stud made of copper with two brass nuts, & a
lead washer shipped on the stud of sufficient weight to keep the float in an upright
position, & ensure buoyancy: As the water rises in the 21 pipe, the float rises in
proportion & the tape travels over the wheel & indicates at the pointer, the draft
of the ship. The officer simply looks through the glass cover to see the tape
line & what it indicates. The thumb screw on the end of the spindle is to spin
the wheel round to make suro that everything works freely.
COMPLETE SPECIFICATION.
Improved Ship's Water Draft Indicator.
ALFRED CORNER 38 Windsor Terrace South Shields, in the County of Durham,
Marine 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 :-
These indicators are made of three types, to suit the differences of construction
in ships cabins, storerooms, and forecastles, and are fitted at the extreme ends, fore
and aft, or centre of ships..

INDICATORS IN MIDSHIP SECTION.
:
1
These indicators can be fitted amidship on the engine room bulkhead & the cock
can be screwed directly onto the ships side or connected to the sea connections of
the main engines.
CONCLUSION.'
1
Having now particularly described & ascertained the nature of my said
invention & in what manner the same is performed, I declare, that what I
claim is
1
First. They are designed to suit all classes of ships & when once fitted, no
attention is afterwards required, as they work automatically."

بہ

page_text: Secondly. Owing to the small diameter of the copper pipe & cock opening, the
water has not time to flow out & in, in proportion to the rise & fall of the ship,
while in motion hence by the use of these indicators all motion is overcome & they
show the true draught of water both in rough & smooth sea. Also the shipmaster
can load the ship to of the required draught of water.
Thirdly. The indicators being made to fit into the extreme ends of the ship,
enables the officer to get the ship into proper trim while loading in open
roadstead..
Fourthly. By their use, the correct weight of bunker coals received on board
can be obtained, and the quantity of coals consumed on a run. Also any increase
of water in the ship, whether by collision or leaking can be observed at once.
Fifthly. The float being of such a large capacity, the difference in buoyancy
between fresh & salt water is only of an inch.
Sixthly. By having the cock placed above light ship water mark enables all
standing water in the pipes, to run out & thoroughly drain away all-sediment.
Seventhily. Their simplicity of construction & durability of the parts will enable
the ship master to place every confidence in their correct working.
Dated this 17th day of September 1895.
