end of the shank, and are connected at their ends by a second pin, upon
which is mounted a tripping piece; the pin passes through the centre of
the tripping piece and the ends of the tripping piece are curved forwards.
to come above and below the end of the shank. By this means when
the anchor is on the ground upon either of its sides it rests upon one of
the ends of the tripping piece and the palms are forced downwards not
only by their own weight but also by the weight of the shank, so that
when a strain comes upon the anchor the palms enter the ground with
certainty, and when they are at the desired angle to the shank they are
prevented from turning further by reason of the two ends of the tripping
picce coming respectively upon the end and upper side of the shank.

page_text: and Ireland, the Channel Islands, and Isle of Man, an Invention for
"IMPROVEMENTS IN ANCHORS," upon the condition (amongst others) that
we, the said Edward Augustus Inglefield and George Charles Lennox
Lenox, our executors or administrators, by an instrument in writing
under our or their hands and seals, or under the hand and seal of one
of us or them, 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 on or
before the Twenty-third day of May, One thousand eight hundred and
seventy-six.
NOW KNOW YE that I, the said George Charles Lennox Lenox,
on behalf of myself and the said Edward Augustus Inglefield, 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 thereof, that is to say :-
This Invention has for its object to improve and cheapen the con-
struction of anchors. For this purpose the arms by which the palms
are carried are brought up to the sides of the shank and are connected
to it near its end by a pin joint. The arms are prolonged beyond the
end of the shank, and are connected at their ends by a second pin, upon
which is mounted a tipping or canting piece; the pin passes through
the centre of the tipping piece, and the ends of the tipping piece stand
up and down in a plane at right angles to the arms. By this means
when the anchor is on the ground upon either of its sides it rests upon
one of the ends of the tipping piece and the palms are forced downwards
not only by their own weight but also by the weight of the shank, so
that when a strain comes upon the anchor the palms enter the ground
with certainty, and when they are at the desired angle to the shank they
are prevented from turning further by reason of the tipping piece coming
in contact with the shank.
Figure 1 shews a side view, and Figure 2 a plan view of an anchor
constructed as above described.
The anchor may either be fitted with a stock or be used without one.
a is the shank; b, b, are the two arms brought up to opposite sides of
the shank and attached together and coupled to the shank near its end
by the bolt c. The arms are, as shewn, prolonged beyond the end of the

page_text: shank, and are again connected together by the bolt d. Upon this
bolt is mounted the tipping piece e.
By forming the anchor with two separate arms and with a separate
tipping piece carried between the arms in rear of the bolt upon which
they turn a cheap and efficient anchor is obtained, whilst at the same
time by reason of the tipping piece being in rear of the bolt upon which
the arms turn the anchor when upon the ground will rest upon one or
other end of the tipping piece and the palms 6' will be depressed not
only by their own weight, as is usually the case in two arm tumbling
anchors heretofore constructed, but also by the weight of the shank.
When the arms are at the desired angle to the shank one of the ends
of the tipping piece e comes against one of the shoulders a¹ upon the
shank, and the arms are thereby stopped from turning further. We
prefer to arrest the movement of the arms when they are at an angle of
from about 40 to 45 degrees to the shank, as is usual in this class of
anchor, but we do not confine ourselves to any precise angle, nor do we
make any claim to arresting the movement of the arms of the class of
anchor to which our Invention relates (that is to two arm tumbling
anchors) at any precise angle to the shank.
Figure 3 shews a modification of the anchor shewn at Figure 2. In
this modification the arms b, b, are slightly different in form to those
shewn at Figure 2, and the shank is made with its two sides parallel
with one another throughout its length.
Having thus described the nature of our Invention, and the manner
of performing the same, we would have it understood that we claim, the
construction of anchors, substantially as herein-before described.
In witness whereof, I, the said George Charles Lennox Lenox,
have hereunto set my hand and seal, this Twentieth day of May,
in the year of our Lord One thousand eight hundred and seventy-
six.
