IMPROVEMENTS IN ANCHORS
Year: 1868

page_text: LETTERS PATENT to Alfred Vincent Newton, of the Office for Patents,
66, Chancery Lane, in the County of Middlesex, Mechanical
Draughtsman, for the Invention of "IMPROVEMENTS IN ANCHORS."-A
communication from abroad by George A. Lloyd and Charles A.
Stewart, both of San Francisco, State of California, United States of
America.
Sealed the 24th July 1868, and dated the 6th April 1868.
PROVISIONAL SPECIFICATION left by the said Alfred Vincent Newton
at the Office of the Commissioners of Patents, with his Petition,
on the 6th April 1868.
I, ALFRED VINCENT NEWTON, of the Office for Patents, 66, Chancery
Lane, in the County of Middlesex, Mechanical Draughtsman, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN ANCHORS,'
to be as follows:-
This Invention relates to improvements in anchors having swinging
in contradistinction to fixed arms or flukes. Upon these flukes ribs
or projections are formed which are intended to strike against stops
formed on the shank of the anchor, and thus limit the amount of

page_text: swing which the flukes are to receive. The stops on the opposite
sides of the shank or the position of the ribs or projections on the
flukes are so arranged with respect to each other, that the flukes
when swung to their full extent will not coincide in position but
will stand at different angles. The object of this is to allow of one
taking the ground first when the anchor lies in one position and of
the other fluke first taking the ground when the anchor lies in the
reverse position.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Alfred Vincent Newton in the Great Seal Patent
Office on the 2nd October 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALFRED
VINCENT NEWTON, of the Office for Patents, 66, Chancery Lane, in the
County of Middlesex, Mechanical Draughtsman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Sixth day of April, in the year of
our Lord One thousand eight hundred and sixty-eight, in the thirty-
first year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Alfred Vincent Newton, Her special
licence that I, the said Alfred Vincent Newton, my executors, admi-
nistrators, and assigns, or such others as I, the said Alfred Vincent
Newton, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times there-
after 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," being a communication to me
from abroad, upon the condition (amongst others) that I, the said Alfred
Vincent Newton, my executors or administrators, by an instrument
in writing under my, or their, or one of their hands and seals, should
particularly 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.

page_text: NOW KNOW YE, that I, the said Alfred Vincent Newton, do
hereby declare the nature of the said 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 Drawing
hereunto annexed and to the letters and figures marked thereon (that
is to say):
The Invention relates to "Improvements in Anchors "
with swinging
flukes, and consists in making lugs on the arm or flukes to strike
or come against projections or stops on the shank of the anchor when
the flukes have swung a proper distance either way to catch and hold
to advantage in the anchoring ground, and in making the flukes to
stand at different angles so that one will catch first when the anchor
is one side up and the opposite one when the anchor is the other
side up.
In the accompanying Drawings Fig. 1 is an elevation of one side
of an anchor constructed according to this Invention, and Figures 2
and 3 are clevations of the anchor as seen at a right angle to Fig. 1;
in Fig. 3 one of the flukes is cut off on the line 2, 2, of Fig. 1.
In these Drawings A is the shank of the anchor provided with a
clevis B for attaching the cable to the anchor in the usual manner.
The lower part of the shank is enlarged and perforated to permit the
insertion of one of the flukes, and a groove is cut in the upper side
of the hole wide enough to let the fluke pass through when it is
put in. This groove is filled by the key e after the fluke is put in,
and the key is fastened by a pin f, Fig. 1. The flukes have wide
flattened ends at D, D, to hold in the mud or bottom, and are made
round at C, C, with lugs or projections a, a, which strike or come
against the stops d, d, on the shank when the flukes have vibrated
far enough in either direction to catch and hold to advantage when
the anchor is dropped. The stops d, d, are forged with the shank
which may be extended below the flukes, and perforated at g for a
becket or to apply a clevis if desired. Fig. 2 shews that the flukes
are not both in the same plane, but stand at different angles, so that
when the anchor is dropped on its side the lower fluke will first catch
the ground.
Having now set forth the nature of the Invention of " Improve-
ments in Anchors" as communicated to me from abroad, and explained

page_text: the manner of carrying the same into effect, I wish it to be understood
that under the above in part recited Letters Patent I claim,-
First. The lugs on the flukes in combination with the stops or pro-
jections on the shank, for the purposes set forth.
Secondly. Making the flukes to stand at different angles so that
one will catch first when the anchor is one side up, and the opposite
one when the anchor is the other side up, substantially as described.
In witness whereof, I, the said Alfred Vincent Newton, have
hereunto set my hand and seal, the Twenty-ninth day of Septem-
ber, in the year of our Lord, One thousand eight hundred and
sixty-eight.
Witness,
J. W. MOFFATT,
