I, HANS LAURITZ HANSEN of 56 Beresford Road, Toxteth Park, Liverpool, in the
County of Lancaster, Heating Engineer, do hereby declare the nature of this
invention to be as follows:-
This invention relates to anchors for ships' use. Anchors of ordinary construction
are when being raised liable to become entangled or caught in the ropes, chains or
other gear that may be hanging or suspended from the bow or side of the ship.
The object of the present invention is to provide an anchor, which will not be
likely so to become entangled when being raised or lowered, and that can be easily
stowed away.
It consists essentially of an anchor preferably with single blade or fluke pivoted
in a framework, and free to move to either side a regulated distance, and so hung or
pivoted that as the anchor is drawn up the blade will assume a position between, and
in the same plane with the shank or frame.
་
The shank of the anchor is formed of a framework of triangular shape between the
two sides of which the fluke is pivoted. The base of the fluke or the pivot on which
it moves, forms the third side of the triangle. The blade or fluke of the anchor thus
being pivoted between two sides of the framework of which the shank is composed, is
free to fall in either direction, so that the fluke will engage with the ground irrespective
of one side or the other of the anchor being turned uppermost. The fluke may be
formed with pivots or trunnions on the base by means of which it is pivoted to the
shank, or a spindle may be passed through both the shank and base of the fluke, or
other pivoting or hinging device may be employed, as may be found most desirable,
also the shank may be formed of one forging, or of separate bars or plates for each
side shackled together at the top, so that the anchor can easily be taken asunder, and
any part removed. The pivots may be secured to the sides and project into the base
of the fluke.
Any suitable method of pivoting the base of the fluke to the shank may be adopted,
the fluke being so pivoted and attached that when the weight of the anchor is brought
to bear upon the cable, that is when the anchor is suspended, the fluke will assumie a
position in the same plane with the shank, and be shielded or protected by it.

page_text: This may be effected either by the use of a double shank, or by projecting the base
of the fluke below the axis on which it is pivoted so as to give sufficient weight to
counterbalance the weight of the fluke.
To the fluke is pivoted a second connecting frame or shank, preferably of similar
contour to the shank, and capable of passing through the space between the sides of it.

is pivoted to the shank, and so that the fluke can be turned to lie in the same plane.
To this connecting frame is attached the chain rope or other cable which carries the
anchor. A hole or eye is cut or provided in the apex of the triangular frame and
through this eye the cable passes. When the anchor is suspended by the cable its
weight causes the shank and connecting piece, and the fluke of the anchor to lie one
within the other in the same plane, and when the cable is slackened the fluke falls out
to one side or the other. A ball or stopper may be placed in the chain to prevent too
great a length passing through the hole as the fluke of the anchor should be held so as

drawn up to the side of the ship the triangular frame or shank slides into a catch, or
between claws fixed a given distance apart the angular shape of the shank causes it to
wedge itself between the claws, and prevents any swinging or oscillation of the
anchor when the ship rolls. This will obviate the necessity of lifting the anchor
inboard as it can always be carried suspended over the ships' side.

Improvements in Anchors for Marine Use.
I, HANS LAURITZ HANSEN of 56, Beresford Road, Toxteth Park, Liverpool in the
County of Lancaster, Heating 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 for ships use. Anchors of ordinary construction
are, when being raised liable to become entangled or caught in the ropes, chains, or
other gear that may be hanging or suspended from the bow or side of the ship.
The object of the present invention is to provide an anchor, which will not be likely
so to become entangled when being raised or lowered, and that can be easily stowed
away.
It consists essentially of an anchor preferably with a single blade or fluke pivoted in
a framework and free to move to either side, a regulated distance, and so hung or
pivoted that as the anchor is drawn up the blade will assume a position between and
in the same plane with the shank or frame.
It will be best described by reference to the annexed drawings.
Figures 1 and 3, front elevations of anchors constructed according to my invention.
Figures 2 and 4 side elevations of same, the flukes being shown in dotted lines,
extended their full extent to one side.
Figure 5 elevation showing position of anchor suspended from ships' side.
In all of these like letters refer to like parts.
A is the shank of the anchor, formed of a framework of triangular shape, B is the
Huke pivoted between the two sides of the shank A. The base 6 of the Huke or the
pivot on which it moves forms the third side of the triangle. The blade or fluke B of
the anchor thus being pivoted between two sides of the framework of which the
shank is composed, is free to fall in either direction, so that the fluke will engage with
the ground irrespective of one side or the other of the anchor being turned uppermost.
The fluke may be formed with pivots or trunnions C on the base by means of which
it is pivoted to the shank as shown in Figure 1, or a spindle may be passed through
both the shank and base of the fluke, or other pivoting or hinging device
may be
employed, as may be found most desirable, also the shank may be formed of one
forging as shown in Figure 1, or of separate bars or plates for each side, shackled
together at the top as in Figure 3, so that the anchor can easily be taken asunder,
and any part removed. The pivots c of Figure 3 are secured to the sides A, and
project into the base of the fluke B. The pivots are cut away at their ends so as to
overlap, and are formed with a catch on the end of each, which engage and hold the
base ends of the shank, so that they cannot be drawn asunder. In addition to the
methods specified, any suitable method of pivoting the base of the fluke to the shank
may be adopted, the fluke being so pivoted and attached that when the weight of the
anchor is brought to bear upon the cable, that is when the anchor is suspended, the

page_text: fluke will assume a position in the same plane with the shank and be shielded or
protected by it.
This may be effected either by the use of a double shank as in Figures 1 and 2, or
by projecting the base of the fluke below the axis on which it is pivoted so as to give
sufficient weight to counterbalance the weight of the fluke as in Figures 3 and 4.
Referring to Figures 1 and 2 D is the second shank preferably of similar shape to
the shank A, pivoted to the fluke at E in similar manner to that described with
reference to the shank A. The second or inner shank is capable of passing through
the space between the sides of the other, and as shown is pivoted to the fluke at a
point nearer to its end than where it is pivoted to the shank A, and so that the fluke
can be turned to lie in the same plane. To this second shank or frame is attached the
chain, rope, or other cable which carries the anchor. A hole or eye a is cut or provided
in the apex of the shank A and through this eye the cable passes. A ball or stopper F
is placed on the chain to prevent too great a length passing through the eye a and so
hold the fluke of the anchor at the proper angle to the shank.
Referring to Figures 3 and 4. 6 is the base made sufficiently heavy below the
pivots e to counterbalance the weight of the fluke B when the anchor is suspended
by the cable. To prevent the fluke of the anchor assuming too great an angle with
the sides of the stock, the base is formed with a projecting piece against which the
ends a¹ of the shank abut when at the required angle.
When suspended from the ships' side, and the whole weight of the anchor is on
the cable, the fluke lies within the shank or frame. As soon as the anchor rests on the
ground, and the weight is relieved from the chain, the fluke falls to one side or the
other, and as the shank still further falls, the fluke engages with the ground in
the usual way. The reverse action takes place as the anchor is drawn up. When it is
drawn up to the side of the ship the triangular frame or shank may slide into a catch,
or between claws G fixed a given distance apart, the angular shape of the shank
causes it to wedge itself between the claws, and prevents any swinging or oscillation
of the anchor when the ship rolls. This will obviate the necessity of lifting the anchor
inboard as it can always be carried suspended over the ships' side.
Having now particularly described and ascertained the nature of the said invention,
and in what manner the same is to be performed, I declare that what I claim is :-
1. An anchor having a fluke or blade free to fall to either side, a regulated distance,
and pivoted inside an angular frame or shank so that when suspended the fluke will
lie inside in the same plane with the shank.
2. An anchor having a double frame or shank with the fluke pivoted thereto, and
free to fall to either side, the inner one of which is attached to the cable, and the
outer one provided with an eye through which the cable passes, and so that when
the anchor is suspended the shanks and fluke will be drawn into the same plane,
substantially as described.
3. An anchor with a pivoted blade or fluke and framework shank constructed and
arranged, substantially as described.
