IMPROVEMENTS IN ANCHORS
Year: 1852

page_text: LETTERS PATENT to Robert William Mitcheson, of the firm of
William Mitcheson and Sons, of Garford Street, in the County of
Middlesex, Anchorsmiths, for the Invention of "IMPROVEMENTS
IN ANCHORS."
Sealed the 16th March 1858, and dated the 25th October 1852.
PROVISIONAL SPECIFICATION left by the said Robert William
Mitcheson at the Office of the Commissioners of Patents, with his
Petition, on the 25th October 1852.
I, ROBERT WILLIAM MITCHESON, of the firm of William Mitcheson
and Sons, of Garford Street, in the County of Middlesex, Anchor
Smiths, do hereby declare the nature of the said Invention for "I■-
PROVEMENTS IN ANCHORS" to be as follows:-
The nature of the Invention consists in improvements on the anchor
provisionally registered by William Mitcheson and Sons on the 12th
day of February 1852. I make the palm convex on the inside, in
order to prevent its getting choked, and turn the outer point of the
palm slightly back in the reverse direction to the curve of the arm, in
order to insure the anchor taking the ground readily. I add a collar
to bind the two parts of the stock to the shank. This collar eases the
strain on the shackle bolt and assists the anchor in taking ground.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
ROBERT WILLIAM MITCHESON, of the firm of William Mitcheson and
Sons, of Garford Street, in the County of Middlesex, Anchor Smiths,

WHEREAS Her most Excellent Majesty Queen Victoria, by Her

year of our Lord One thousand eight hundred and fifty-two, in the
sixteenth year of Her reign, did, for Herself, Her heirs and succes-
sors, give and grant unto me, the said Robert William Mitcheson,
Her special licence that I, the said Robert William Mitcheson, my
executors, administrators, and assigns, or such others as I, the suid
Robert William Mitcheson, my executors, administrators, and assigns,
should at any time agree with, and no others, from time to time
and at all times thereafter during the term therein expressed, should
and lawfully might make, use, exercise, and vend, within the United
Kingdom of Great Britain and Ireland, the Channel Islands, and
Isle of Man, an Invention for "IMPROVEMENTS IN ANCHORS," upon the
condition (amongst others) that I, the said Robert William Mitcheson,
by an instrument in writing under my hand and seal, should particu-
larly describe and ascertain the nature of the said Invention, and in
what manner the same was to be performed, and cause the same to
be filed in the Great Seal Patent Office within six calendar months
next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Robert William Mitcheson, do
hereby declare the nature of my said Invention, and in what manner
the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:
My Invention has relation to improvements on the anchor provi-
sionally registered by William Mitcheson and Sons, the 12th day of
February, One thousand eight hundred and fifty-two, in pursuance of
the provisions of the "Designs Act, 1850," and completely registered

page_text: the Ninth day of December, One thousand eight hundred and fifty-
three, in pursuance of the provisions of the said Act and of the "Designs
Act, 1843." And my Invention consists, first, in so forming the palms
of anchors that they shall not be liable to become choked or clogged;
and, second, in so forming the extremity of the palms that the anchor
shall the more readily take the ground. And the manner in which
my said Invention may be performed is as follows:-
Figure 1, is a front elevation of an anchor constructed according to
my present Invention; and Figure 2, a side elevation with part of the
stock removed. Figure 3, is a plan of the palm. Figures 4, 5, and 6,
are sections of different parts. In order to prevent the palmis A, A,
from clogging or being filled with mud, earth, &c. I make their faces
convex, as shown in the plan, Figure 3, and section, Figure 4; and I
give to the extremity of the palms of the anchor an inclination in the
reverse direction to the curve of the arms, as shewn at a, a, Figures
2, and 3, to enable the anchor more readily to take the ground.
And having now described the nature of my said Invention, and
in what manner the same is to be performed, I declare that I claim,-
First, the making of the palms of anchors convex; and, second, I
claim the inclining of the extremity of the palms of anchors in a
reverse direction to the curve of the arms, as herein-before described,
and represented in the Drawings hereunto annexed.
In witness whereof, I, the said Robert William Mitcheson, have
hereunto set my hand and seal, this Twenty-fifth day of April,
One thousand eight hundred and fifty-three.
ROBERT WILLIAM MITCHESON. (LS.)
