I, EDWARD REYNOLDS, of Vickers Sons and Company Limited of Sheffield in the
County of York, Engineer and Steel Manufacturer, do hereby declare the nature of
this invention to be as follows :-
My invention relates to an improved construction of anchors with tumbling flukes,
the essential feature of which consists in constructing the flukes together with the
head part thereof as a single steel casting with a central boss having an opening
through which the shank passes and to which it is pivotted by a pin or bolt.
The several parts of the flukes, head and boss are so proportioned as to shape and
thickness, as to insure the production of a sound casting, the head part being preferably
formed of a trough shaped cross section on each side of the central boss, so that the
lynch pin forming the pivot can be placed entirely within the trough of the fluke head
and thus be protected from injury; the opening of the boss through which the shank
passes is so formed that when the flukes are canted, the shank takes a bearing both on
a face on the inner side of the boss and on a face on the outer side of the boss so that
the lynch pin, which is situated between the two faces, is relieved of all strain except
the direct pull of the cable, when the ship is dragging at the anchor or when this is
being pulled up, and a very strong purchase is afforded for the shank.
The flukes are so formed with sharp angular ends that when lying upon the ground
it is impossible for them to skid, a bite on the ground being insured as soon as a pull
is put upon the shank in whatever position the anchor may lie, so that the necessity for
a stock is entirely obviated.
The construction of the improved anchor whereby I obtain the above mentioned
advantages, will be readily understood on reference to the accompanying drawings in
which Fig. 1 shews a front view of the anchor partly in section, Fig. 2 a side view of
the same with the flukes canted, Fig. 3 a sectional side view with the flukes lying in
the plane of the shank, Fig. 4 an end view and Fig. 5 a section through one of the
flukes on line XX.
The fluke-head A and flukes A¹ A' are formed of a single steel casting, the head A
being formed preferably of a trough shaped cross section on each side of the central
boss A, which is formed with an opening B through which the shank passes, as

shewn more clearly at Fig. 3. The boss A2 is of considerably greater width than the
trough shaped parts A of the head and these have feathers or ribs A³ on each side
thereof extending to the same width as the boss; these ribs in dragging on the ground
greatly facilitate the canting downward of the flukes.
The eye of the shank is pivotted to the boss A2 by means of a lynch pin D, which
is preferably situated entirely within the trough of the head as shewn, and being thus
effectually protected against blows or dislodgment, it can be securely held in position
by a small split pin E passing through the sides of the trough in front of the head of the
lynch pin. The split pin is also protected by the projecting ribs A³ against dislodgment.
The opening B of the boss is formed with four sloped faces B B B B² of such
inclination that when the flukes are canted over to the full extent, the shank abuts with
its inner part against one or other of the faces B' and with its outer part against one
or other of the faces B2, thus relieving the linch pin D of all strain excepting the pull
of the cable, so that it may be made of comparatively small size. The eye of the shank
is swelled out as shewn so as to reduce the space in the opening on each side thereof as
much as possible in order to prevent a large sized stone getting jammed therein.
The flukes are made of an H shaped cross section thus affording sufficient strength
with a minimum of metal, the side ribs terminating in sharp rectangular edges such
as will readily bite in the ground as soon as they are drawn along it, such biting action
being increased as before stated by the downward dragging action upon the flukes by
the ribs A³.
It will be seen that all parts of the flukes head, and boss are so proportioned in
thickness and shape as to enable a very perfect steel casting to be produced. Although
I prefer to make the fluke-head of a trough shape as shewn, yet it may also be made
tubular, or of any other sectional form affording the requisite strength without very
great thickness of metal.

page_text: I, EDWARD REYNOLDS, of Vickers Sons and Company Limited of Sheffield in the
County of York, Engineer and Steel Manufacturer, 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:-
My invention relates to an improved construction of anchors with tumbling flukes,
the essential feature of which consists in constructing the flukes together with the
head part thereof as a single steel casting with a central boss having an opening
through which the shank passes and to which it is pivotted by a pin or bolt.
The several parts of the flukes, head and boss are so proportioned as to shape and
thickness, as to insure the production of a sound casting, the head part being preferably
formed of a trough shaped cross section on each side of the central boss, so that the
lynch pin forming the pivot can be placed entirely within the trough of the fluke head
and thus be protected from injury the opening of the boss through which the shank
passes is so formed that when the flukes are canted, the shank takes a bearing both on
a face on the inner side of the boss and on a face on the outer side of the boss so that
the lynch pin, which is situated between the two faces, is relieved of all strain except
the direct pull of the cable, when the ship is dragging at the anchor or when this is
being pulled up, and very strong purchase is afforded to the shank.
The flukes are so formed with sharp angular ends that when lying upon the ground
it is impossible for them to skid, a bite on the ground being ensured as soon as a pull
is put upon the shank in whatever position the anchor may lie, so that the necessity
for a stock is entirely obviated.
The construction of the improved anchor whereby I obtain the above mentioned
advantages, will be readily understood on reference to the drawings accompanying my
Provisional Specification. Fig. 1 shews a front view of the anchor partly in section,
Fig. 2 a side view of the same with the flukes canted, Fig. 3 a sectional side view with
the flukes lying in the plane of the shank, Fig. 4 an end view and Fig. 5 a section
through one of the flukes on line XX.
The fluke head A and flukes A' A¹ are formed of a single steel casting, the head A
being formed preferably of a trough shaped cross section on each side of the central
boss A, which is formed with an opening B through which the shank passes, as shewn
more clearly at Fig. 3. The boss A is of considerably greater width than the trough
shaped parts A of the head and these have feathers or ribs A³ on each side thereof
extending to the same width as the boss; these ribs in dragging on the ground greatly
facilitate the canting downward of the flukes.
The eye of the shank C is pivotted to the boss A² by means of a lynch pin D, which
is preferably situated entirely within the trough of the head as shewn, and being thus
effectually protected against blows or dislodgment, it can be securely held in position
by a small split pin E passing through the sides of the trough in front of the head of.

dislodgment.
The opening B of the boss is formed with four sloped faces B₁ B1 B2 B3² of such
inclination that when the flukes are canted over to the full extent, the shank abuts with
its inner part against one or other of the faces B' and with its outer part against one
or other of the faces-132, thus relieving the lynch pin D of all strain excepting the pull
of the cable, so that it may be made of comparatively small size. The eye of the shank
is swelled out as shewn so as to reduce the space in the opening on each side thereof
as much as possible in order to prevent a large sized stone getting jammed therein.
The flukes are made of an H shaped cross section thus affording sufficient strength
with a minimum of metal, the side ribs terminating in sharp rectangular edges such
as will readily bite in the ground as soon as they are drawn along it, such biting action
being increased as before stated by the downward dragging action upon the flukes by
the ribs A³.
It will be seen that all parts of the flukes, head and boss are so proportioned in
thickness and shape as to enable a very perfect steel casting to be produced. Although
I prefer to make the fluke-head of a trough shape as shewn, yet it may also be made
tubular, or of any other sectional form affording the requisite strength without very
great thickness of metal.
Having now particularly described and ascertained the nature of this invention and
in what manner the same is to be performed, I declare that I make no general claim
to the construction of an anchor having the two flukes and the head and its boss cast
in one piece of steel or other metal, but what I claim is
1. The construction of anchor as herein described and illustrated by the accompanying
drawings.
2. In an anchor such as is referred to in the preceding claim, forming the hole of
the boss through which the shank passes with sloping faces to form stop bearings for
the shank in its extreme angular positions, as and for the purpose herein set forth.
Dated this 21st day of February 1887.
