IMPROVEMENTS IN ANCHORS
Year: 1838

page_text: PORTER'S SPECIFICATION.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
WILLIAM HENRY PORTER, of Russia Row, Milk Street, Cheapside, in
the City of London, Merchant, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by
Her Letters Patent, under the Great Seal of Great Britain, bearing date
at Westminster the Fifteenth day of August, in the second year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said William Henry Porter, Her especial licence, full power,
sole privilege, and authority that I, the said William Henry Porter,
my exors., admors., and assigns, or such others as I, the said William
Henry Porter, my exors., admors., or assigns, should at any time agree
with, and no others, from time to time and at all times during the
term of years therein expressed, should and lawfully might make, use,
exercise, and vend, within England, Wales, and the Town of Berwick-
upon-Tweed, my Invention of "IMPROVEMENTS IN ANCHORS," in which
said Letters Patent is contained a proviso, that I, the said William
Henry Porter, shall cause a particular description of the nature of my
said Invention, and in what manner the same is to be performed, to be
inrolled in Her said Majesty's High Court of Chancery within six
calendar months next and immediately after the date of the said in

page_text: part recited Letters Patent, as in and by the same, reference being
thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso I, the
said William Henry Porter, do hereby declare the nature of my In-
vention, and the manner in which the same is to be performed are
fully described and ascertained in and by the following statement
thereof, reference being had to the Drawing hereunto annexd, and to
the figures and letters marked thereon, that is to say:
My Invention relates to a mode of constructing and applying the arms
and flukes to the stem or shank cf an anchor by means of an axis,
whereby an anchor made according to my Invention will be less liable
to be fouled by the cable when the vessel is swinging; and when one
fluke is holding in the ground the other will lie on and be sustained by
the shank or stem; by which means the vessel will not be liable to
have her bottom injured by the upper fluke; and further, owing to the
facility of separating the parts, anchors, when constructed according
to my Invention, may be stowed. away with greater convenience than
anchors of other constructions heretofore made.
DESCRIPTION OF THE DRAWING.
Figure 1, shews an anchor, made according to my improvements,
holding in the ground. Figure 2, shews a like anchor out of the
ground. Figure 3, shews the various parts of my improvements sepa-
rately. In each of these Figures the same letters indicate similar
parts, being the stem or shank, which has two projections at b, b.
The object of these projections is, that when an anchor is holding in
the ground the upper fluke may be below one of the projections b, and
in such manner that in the event of the cable passing along the shank
it may be guided over the upper fluke and arm of the anchor, and go
clear; but these projections are not absolutely necessary. c, is a stock,
which is shewn to be of iron, but a wood stock may be applied (as is
well understood) to anchors having my Invention applied thereto. The
lower end of the shank or stem a, of the anchor is forged or made in
such manner as to receive the arms d, between the two cheeks, and the
two cheeks, as well as the arms, must be of sufficient strength to receive

page_text: a pin or axis e, through them, such pin or bolt being secured in its
place by a split cotter or other fastening and washer, or otherwise, as
may be; all which is clearly shewn in the Drawing. f, f, are projec-
tions on the arms, which aid in opening out the under arm and fluke
as the anchor is drawn along the ground.
I would remark, that I am aware that anchors have been before
made with arms capable of movement in the shank or stem; I do not,
therefore, claim the same generally. But what I claim is, the mode of
constructing and combining the parts a, d, e, f, as above described.
In witness whereof, I, the said William Henry Porter, have
hereunto set my hand and seal, this Ninth day of February, One
thousand eight hundred and thirty-nine.
WILLIAM HENRY (L.S.) PORTER.
WILLIAM HENRY (L.S.) PORTER.
AND BE IT REMEMBERED, That on the Ninth day of February, D
5 in the year of our Lord 1839, the aforesaid William Henry Porter
came before our said Lady the Queen in Her Chancery, and acknow-
ledged the Specification aforesaid, and all and everything therein
contained and specified in form above written; and also the Speci-
fication aforesaid was stamped according to the tenor of the statute
0 made for that purpose.
