IMPROVEMENTS IN ANCHORS
Year: 1875

page_text: LETTERS PATENT to William Robert Lake, of the Firm of Haseltine,
Lake, & Co., Patent Agents, Southampton Buildings, London,
for the Invention of "IMPROVEMENTS IN ANCHORS."-A communication
from abroad by Joseph Stokes Williams, of Riverton, New Jersey,
PROVISIONAL SPECIFICATION left by the said William Robert Lake
at the Office of the Commissioners of Patents, with his Petition, on
the 4th August 1875.
I, WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co.,
5 Patent Agents, Southampton Buildings, London, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN ANCHORS," a com-
munication, to be as follows :-
This Invention relates to an anchor having its fluke arm swiveled or
pivoted to the shank thereof, and it consists in limiting the motions of

page_text: the flukes by means of a rigid connection or connections secured to the
flukes and adapted to bear against the shank of the anchor.
The flukes have an arm which is swiveled or pivoted in the crown or
lower portion of the shank, and oscillates thereon. To the flukes at
points between the palms and arms there is secured a connecting bar,
rod, or chain, which extends transversely from fluke to fluke, and plays
in a transverse opening or space in the lower part of the shank above the
bearing of the said fluke arm.
It will be seen that when the anchor is "let go "the fluke arm turns
or swings in the shank, and causes the flukes to cant. The transverse
connection, besides serving to strengthen the flukes, comes solidly to a
bearing against the wall at one side of the opening, thus limiting the
motion of the flukes and transferring the strain thereon to the shank,
the same result being produced when the flukes swing to the other side
of the shank, the wall of the said opening then providing a bearing for
the said transverse connection; but the flukes may have, in lieu of a
single connection which bears against the inner faces of the walls, two
bent or U shaped connections, which will come to bearings solidly on the
outside of the walls, the result being the same as that stated.
If desired a bend may be formed in the said transverse connection at
a point where the said connection will bear against the inner walls of
the shank, the strength of the connection being thereby increased, but
the operation is similar to that already set forth.

Office on the 3rd February 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria. by Her 20

page_text: our Lord One thousand eight hundred and seventy-five, in the thirty-
ninth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said William Robert Lake, Her special
licence that I, the said William Robert Lake, my executors, adminis-
trators, and assigns, or such others as I, the said William Robert
Lake, 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," a communication to me from
abroad by Joseph Stokes Williams, of Riverton, New Jersey, United
States of America, upon the condition (amongst others) that I, the
said William Robert Lake, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands and
scals, 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

page_text: A represents the shank of an anchor, and B the flukes, whose arm
is swiveled or pivoted in the crown or lower portion of the shank, and
oscillates therein. To the flukes B at points between the palms D and
arms C there is secured a connecting bar, rod, or chain E, which extends
transversely from fluke to fluke, and plays in a transverse opening or
space F in the lower part of shank A above the bearing of the fluke
arm C.
It will be seen that when the anchor is "let go " the fluke arm turns
or swings in the shank, and causes the flukes to cant or assume the
operative position shown in Figure 2. The transverse connection E, besides
serving to strengthen the flukes, comes solidly to a bearing against the
wall a at one side of the opening F, thus limiting the motion of the
flukes and transferring the strain thereon to the shank A. The same
result is produced when the flukes swing to the other side of the shank,
the wall a of the opening F then providing a bearing for the con-
cction E; but the flukes may have, in lieu of a single connection
which bears against the inner faces of the walls a, a³, two bent or
U shaped connections, which will come to bearings solidly on the outside
of the walls a, a, the result being the same as that above stated.
If desired a bend (sce dotted lines, Figure 1) may be formed in the
connection E at a point where said connection will bear against the
inner walls of the shank, the strength of the connection being thereby
increased, but the operation is similar to that above set forth.
Having thus fully described the said Invention as communicated to
me by my foreign correspondent, and the manner of performing the
same, I wish it understood that I claim,-
First. Limiting the motions of swiveled or pivoted flukes by means of
a rigid connection or connections secured to the flukes and adapted to
bear against the shank of the anchor.
Second. The shank in combination with pivoted fluke arms having
connections bearing on the inside or outside walls of the shank, as above
set forth

page_text: Third. The flukes B swiveled or pivoted to the shank of the anchor,
and having a transverse rigid connection E, as above specified.
In witness whereof, I, the said William Robert Lake, have here-
unto set my hand and seal, this Third day of February, in
the year of our Lord One thousand eight hundred and seventy-
six
