AN IMPROVEMENT OR IMPROVEMENTS IN ANCHORS
Year: 1830

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
PERING, of Exmouth, in the County of Devon, Esquire, send greeting.
WHEREAS by His present Majesty King William the Fourth's Letters
Patent, bearing date at Westminster, the Sixth day of October last, after
reciting that I, the said Richard Pering; had represented, as therein mentioned,
that I had invented "AN IMPROVEMENT OR IMPROVEMENTS IN ANCHORS," His.
said Majesty, for Himself, His heirs, and successors, did give and grant unto
me, the said Richard Pering, His special licence, full power, sole privilege and
authority, that I, the said Richard Pering, iny exors, adññiors, and assigns, and
every of them, by myself and themselves, and by my and their deputy or deputies
or agents, or such others as I, the said Richard Pering, my exors, adiñiors,
or 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 expressed, should
and lawfully might make, use, exercise, and vend my said Invention within
England and Wales, and the Town of Berwick-upon-Tweed, and also in
His Majesty's Colonies and Plantations abroad; in which said Letters Patent
there is contained a proviso, obliging me, the said Richard Pering, by an
instrument in writing under my hand and seal, particularly to describe and
ascertain the nature of my said Invention, and in what manner the same is
to be performed, and to cause the same to be enrolled in His Majesty's High
Court of Chancery within six calender months next and immediately after the
date of the said recited Letters Patent, as in and by the same, reference being
thereto had, will more fully appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
Richard Pering, do hereby describe and ascertain the nature of my said
Invention, and in what manner the same is to be performed, by the Plan or
Drawing hereunto annexed, and the following description thereof, that is to.
say:-
My Invention consists in the application to the anchor (whether as
constructed upon my Patent of the Twenty-third of July, One thousand
eight hundred and thirteen, or in any other manner,) of the principle of
increasing the power by increasing the dimensions in the direction of the
strain, a principle now in such application, and thereby presenting a greater
resistance to the strains to which the anchor is most exposed. The Figure
No. 1 in the annexed Drawing is a section of the shank and arms of an
anchor made upon the above principle; No. 2, a section of the shank and
arms of an anchor made under my former Patent; and No. 8, a section of
the shank and arms of an anchor made in tho ordinary manner, the weight of
the threo anchors being the same. In sections No. 1 and 2, a, b, is the line
drawn through the centre in the direction of the strain, (which strain as is
well known lies in the plane containing the shank and arms); c, d, the line
drawn at right angles with the former. The latter line is meant to be of the
same length in both Figures, whilst in No. 1 the line a, b, is of much greater
length than in the Figure 2, such additional length being obtained by material
saved from parts where strength is not so much required, namely, at the points
c, f, g, h. The contemplated improvement will be found in the increased
strength of an anchor made upon the principle of the Figure 1, as compared
with anchors of the same weight made upon the principles before in use, or in
the increased lightness of an anchor made upon the improved plan, as compared
with other anchors of the same strength. The manner in which my Invention
is to be performed or carried into effect is the same in the component parts
as is described by me in the Specification to the before-mentioned Patent of
the Twenty-third July, One thousand eight hundred and thirteen, and in the
Drawings annexed to such Specification, to which Specification and Drawings,
as well as to the copies or illustrations thereof hereto annexed I refer, my
Invention consisting in the form of the anchor and not in the mode of
constuction. The description referred to is as follows, that is to say :-
First, in continuing the grain of the iron from the shank into the arms,
similar to the shape of a knee or arm of a tree, whoreby the necessity of
effecting a junction at the crown, as at present welded, is superseded.
Secondly, in carrying a piece of iron across the crown from tlic centre of

page_text: each arm, making thereby a perfect truss, which when welded resembles the
form of a truss beam.
Thirdly, in forming both the shank and arms of flat bars placed so as to
act edgewise on the line of resistance when the anchor is in the ground.
And, fourthly, in forming the largest part of the shank one-third down
from the crown in a line across from toe to toe of the arms.
In witness whereof, I have hereunto set my hand and seal, the Eighth
day of March, in the year of our Lord One thousand eight hundred
and thirty-one
Inrolled the Sixth day of April, in the year of our Lord One thousand
eight hundred and thirty-one.
