Improvements in Anchors.
I, HENRY CHARLTON, of 1 Millfield Terrace, Gateshead-on-Tyne, Engineer,
do hereby declare the nature of this invention to be as follows:-
This invention relates to anchors of the "Improved Martin's Anchor" type.
The flukes and arms together with a box piece are all formed in one casting
which is of steel.
The arms are of trough like form, open in rear whilst the box has an opening in
front to receive the head of the shank. After the shank head has been inserted it
is secured by a pin passed in rear of the arms through the eye and through the
two ends of the box. The angle through which the fluke piece is free to turn is
regulated by a ridge or stop at the back of the box and within it and by shoulders
upon the shank head one on either side.
The box is perforated at the back to allow mud or sand entering to work out.
The box has shoulders or projections one on each side to serve as tripping pieces.
Dated this 15th day of March 1893.

I, HENRY CHARLTON, of 1 Millfield Terrace, Gateshead-on-Tyne, Engineer,
do hereby declare the nature of this invention and in what manner the same is to
be performed to be particularly described and ascertained in and by the following
statement :-
This invention relates to anchors of the "Improved Martin's Anchor" type.
The flukes and arms together with a box piece are all formed in one casting
which is of steel.
The arms are of trough like form, open in rear whilst the box has an opening

is regulated by a ridge or stop at the back of the box and within it and by shoulders
upon the shank head one on either side.
The box has shoulders or projections one on each side to serve as tripping
pieces.
In order that my invention may be fully understood and readily carried into
effect I will proceed to describe the drawings annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a plan of an anchor in accordance with my invention. Figure 2 is a
side view and Figure 3 is an end view of the same.

Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. An anchor substantially as described, in which the flukes, arms, box piece and
stop form one casting and in which a shank head having shoulders upon it to abut
upon the stop is inserted into the box piece from the front and secured by a pin
inserted in rear of the arms through the eye of the shank and the ends of
the box.
2. An anchor substantially as represented by the annexed drawings.
