CERTAIN IMPROVED ARRANGEMENTS FOR RAISING SHIPS' ANCHORS, AND OTHER PURPOSES
Year: 1844

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
JOHNSTONE, of Southampton, in the County of Hants, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent under the Great Seal of Great Britain, bearing date at Westminster,
the Twenty-first day of December, in the year of our Lord One thousand eight
hundred and forty-four, in the eighth year of Her reign, did give and grant
unto me, the said Charles Johnstone, my exors, admors, and assigns, Her
especial licence, full power, sole privilege and authority, that I, the said
Charles Johnstone, my exors, adñmors, and assigns, and such others as I, the
said Charles Johnstone, my exors, admors, and assigns, should at any time
agree with, and no others, from time to time and at all times thereafter, during
the term of years therein mentioned, should and lawfully might make, use,
exercise, and vend, within that part of the United Kingdom of Great Britain
and Ireland called England, Her Dominion of Wales, and Town of Berwick-
upon-Tweed, and in Her Islands of Jersey, Guernsey, Alderney, Sark, and
Man, and also in all Her Colonies and Plantations abroad, my Invention of
"CERTAIN IMPROVED ARRANGEMENTS FOR RAISING SHIPS' ANCHORS, AND OTHER
PURPOSES;" in which said Letters Patent there is contained a proviso that I,
the said Charles Johnstone, shall particularly describe and ascertain the nature
of my said Invention, and in what manner the same is to be perormed, by an
instrument in writing under my hand and seal, and cause the same to be
enrolled in Her said Majesty's High Court of Chancery within six calendar

page_text: months next and immediately after the date of the said Letters Patent, as,
reference being thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Charles Johnstone, do hereby declare the nature of my Invention, and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement, reference being had to the
Drawings therein referred to (that is to say):-
Figure 1 is a perspective view of a ship's windlass, fitted with my said
improvements at the larboard side, though my improvements may be fitted to
either end or in the middle of the windlass. A is the ordinary paul bit; B,
the ordinary paul; C, the ordinary toothed paul wheel; and D, D, the barrel
of the windlass, the axes of which turn as usual in the bit heads E, E. So far
this description is applicable to an ordinary ship's windlass; and I will now
proceed to describe my said improvements. F is another toothed paul wheel,
as represented at the end of the barrel of the windlass, and connected with the
scolloped shell cable holder and groove for the stopper band, which together
form one piece of cast iron, as seen at Figure 2. G is a double arm claw lever
attached to the bit head E by an axis upon which it turns. H, H, are two
claws connected with the claw lever G, one on each side of the axis, and they
are both made to fall and act on the same side of the toothed paul wheel F, as
shewn in the Drawing. L, L, are handle levers, which are received into the
double arm claw lever G; and it will be easily seen, that if the levers are
worked up and down by manual or other power, the windlass will be pulled
round with great force at every stroke as the claws fall into the teeth of the
wheel, and when in motion one claw is always pulling round the windlass by
its ascending movement while the other claw at the same time is descending
to catch hold of a fresh tooth, which it pulls upwards, while the former claw is
in its turn descending to perform the same operation, and thereby causes a
continuous motion to the windlass. The scolloped shell in which the iron
chain cable appears in the Drawing is upon a new plan to hold without slipping
a chain cable of any size, as shewn by the opening form of the scollops at the
top and bottom of Figure 2. J, J, J, is an ordinary stopper or break as used
in cranes, &c. Figure 2, as already stated, forms one piece of ironwork, and
instead of being solidly wedged to the windlass barrel D, D, like the paul wheel
C, the said Figure 2 is made to revolve on the end of the windlass barrel D, D,
to which it can be firmly connected at pleasure by the sliding bolt K, and the
windlass barrel D, D, by the use of ordinary hand spikes, can also revolve
independently of Figure 2. By this means the great advantage of two
separate windlasses is obtained, and if my improvements are applied to the

page_text: opposite or starboard side, the advantages of three separate windlasses would
be produced. Figure 3 represents the end of the windlass barrel D, D, upon
which Figure 2 is made to revolve. Figure 4 is a separate view of the double
arm claw lever G. Figure 5 is a view of the handle levers L. It is only
necessary further to state, that by detaching the claws H, II, from the toothed
paul wheel F, the whole of Figure 2 will revolve either backwards or forwards,
and thereby admit of the anchor being cast with great velocity, as the iron
cable running in the scolloped shell will pay itself out from the locker below,
through a deck pipe placed under the windlass, through which the cable will
stow itself away upon the anchor being weighed, as at every turn of the wind-
lass the cable will release itself from the scolloped shell, and fall through the
deck pipe into the locker again. In casting anchor the revolutions of the
windlass can be instantly stopped by means of the break J, J, J, and the wind-
lass will be permanently secured by causing the claws H, H, to fall into their
places on the toothed wheel.
Having now described the nature of my said Invention, and in what manner
the same is to be performed, I wish it to be understood, that what I claim as
my Invention is, the double arm claw lever acting on the paul wheel F, forcing
round the windlass barrel by means of the claws, the power being applied to
the lever handles as above described. And I also claim as my Invention the
new form of a scolloped shell (as shewn in Figure 2) in conjunction with the
arrangements herein-before described.
In conclusion I would remark, that the arrangements herein-before described
may be employed in raising other heavy weights, and for similar purposes.
In witness whereof, I, the said Charles Johnstone, have hereunto set my
hand and seal, the Seventh day of May, in the year of our Lord One
thousand eight hundred and forty-five.

page_text: Parchment. Writing, bearing date on or about the Seventh day of May, One
thousand eight hundred and forty-five, and purporting to be a Specification
under the hand and seal of Charles Johnstone therein described, whose signature
is attested by George Hutton, Esquire, hath been this day produced to this
:Deponent. And this Deponent: further saith, that he has known the said
George Hutton. for the last preceding twenty years, and that he knows the
said George Hutton has held the office of Her Brittanick Majesty's Vice
Consul at Havre de Grace, in the Kingdom of France, for the last preceding
three years up to the present time, and that he now holds the aforesaid office
of Vice Consul. And this Deponent further saith, that he is pefectly acquainted
with the handwriting of the said George Hutton, having carried on a corre-
spondence with him for the last preceding ten years, and that be, this
Deponent, having carefully looked at and inspected the attestation of the
signature by the said Charles Johnstone to the said Parchment Writing or
Specification, and the name "Geo. Hutton" thereunder signed as the party so
attesting such signature, knows that such attestation and name respectively
are the proper handwriting of the said George Hutton.
