We, JOHN FORD, of 2, Netherton Hill, near Dudley, Worcestershire, Chain Maker,
WILLIAM JAMES Cox, of Old Bush Inn, Factory, Tipton, Staffordshire, Forgeman,
and EDWARD FORD, of 34, Park Lane West, Tipton, Staffordshire, aforesaid, Chain
Maker, do hereby declare the nature of this invention to be as follows:-
This invention has reference to those anchors in which the head and the shank are
made separate from each other and hinged or pivotted together so as to allow the arms
of the head to move together on either side of the shank through an angle of about
forty five degrees when their motion is arrested by suitable stops; and this invention
consists in the construction and arrangement of the parts of such anchors whereby the
head is so connected to the shank that there is little possibility of its becoming
detached therefrom when in use but so that it can readily be removed when required;
and further the tripping action of the head is rendered certain as the stops which limit
its movement are so arranged that it cannot possibly become choked by sand, stones or
the like when the anchor is in use.
In carrying out our invention we make an enlargement at the centre of the head
which takes the form of two lateral projections one on either side of the head. The
plane in which these side projections lie is somewhere about at right angles to the
plane of the arms. The head is pierced centrally by an oblong hole at right angles to
the plane of the arms and through this hole the shank passes. This oblong hole
extends far enough at each side to allow of the arms falling a-trip at either side of the
shank. The joint pin which secures the head to the shank passes through the shank
and projects at each side, these projecting parts fitting into recesses in the underside
of the head where it is secured by two plates one at either side of the shank which
cover the said recesses and are each secured to the head preferably by two screw bolts,
screws or rivets. To remove the head the said plates are first removed by taking
out the bolts, screws or rivets when the head will be free to be moved up the shank
and allow of the joint pin being removed and the shank drawn out of its slot in the
head.

page_text: When the arms are a-trip on either side of the shank one of the herein before
mentioned side projections comes into contact with the shank above the joint pin and
the other side projection comes in contact with the shank below the joint pin thus
forming a very sound stop to prevent the arms moving too far.
The said side
projections stand out on each side of the head far enough to raise its centre some
distance above the ground line so as to cause the arms to be well "a-trip," even
when the anchor is lying on the ground, and the palms to grip and become further
embedded.
As the hole in the head through which the shank passes extends right through the
head and is made larger than the shank, the head cannot become choked by stones, etc.,
as is the fault with some of the tripping anchors now in use.
The said joint pin of the head is preferably fixed thereto as above described as by
that arrangement it is not liable to become loose therefrom but in a modification of
our invention two ears are forined underneath the head one at either side of the shank
through which the said joint pin passes and through the shank.
By making the head of the form above described it can be forged in one pieco
without welding.

page_text: We, JOHN FORD, of 2, Netherton Hill, near Dudley, Worcestershire, Chain Måker,
WILLIAM JAMES Cox, of Old Bush Inn, Factory, Tipton, Staffordshire, Forgeman,
and EDWARD FORD, of 34, Park Lane West, Tipton, Staffordshire, Chain Maker,
do hereby declare the nature of this invention and in what manner the same is to
be perforined, to be particularly described and ascertained in and by the following
statement:-
This invention has reference to those anchors in which the head and the shank aro
made separate from each other and hinged or pivotted together so as to allow the arms
of the head to move together on either side of the shank through an angle of about
forty five degrees when their motion is arrested by suitable stops; and this invention
consists in the construction and arrangement of the parts of such anchors whereby the
head is so connected to the shank that there is little possibility of its becoming
detached therefrom when in use but so that it can readily be removed when required;
and further the tripping action of the head is rendered certain as the stops which limit
its movement are so arranged that it cannot possibly become choked by sand, stones
or the like when the anchor is in use.
In carrying out our invention we make an enlargement at the centre of the head
which takes the form of two lateral projections one on either side of the head. Tho
plane in which these side projections lie is somewhere about at right angles to the
plane of the arms. The head is pierced centrally by an oblong hole at right angles to
the plane of the arms and through this hole the shank passes. This oblong hole
extends far enough at each side to allow of the arms falling a-trip at either side of the
shank. The joint pin which secures the head to the shank passes through the shank
and projects at each side, these projecting parts fitting into recesses in the underside
of the head where it is secured by two plates one at either side of the shank which
cover the said recesses and are each secured to the head preferably by two screw bolts,
screws or rivets. To remove the head the said plates are first removed by taking
out the bolts, screws or rivets when the head will be free to be moved up the shank
and allow of the joint pin being removed and the shank drawn out of its slot in the
head.
When the arms are a-trip on either side of the shank one of the herein before
mentioned side projections comes into contact with the shank above the joint pin and
the other side projection comes in contact with the shank below the joint pin thus
forming a very sound stop to prevent the arms moving too far. The said side
projections stand out on each side of the head far enough to raise its centre some
distance above the ground line so as to cause the arms to be well "a-trip," even when
the anchor is lying on the ground, and the palins to grip and become further
embedded.

page_text: As the hole in the head through which the shank passes extends right through the
head and is made larger than the shank, the head cannot become choked by stones, etc.,
as is the fault with some of the tripping anchors now in use.
By making the head of the form above described it can be forged in one piece without
welding.
On the accompanying drawings Fig. 1 represents in part sectional plan, an anchor
constructed according to this invention; Fig. 2 is a part sectional side elevation of the
same; Fig. 3 is an end view of the same looking towards the underside of the head;
Fig. 4 is an end view of the head with the shank removed; Fig. 5 represents one of
the plates separately which hold the joint pin of the head in place and Fig. 6 represents
the same anchor and shews how the head can be detached from the shank. The
remaining Figures illustrate modifications of our invention as hereinafter more fully
set forth.
The same letters of reference indicate like parts in all the Figures.
Referring firstly more particularly to Figs. 1 to 6 both inclusive. A is the shank
of the anchor and B is the head which is a solid forging of wrought iron or steel
having the usual two arms or flukes 1, 2, are the two lateral projections one on
either side of and together forming the enlargement at the centre of the
head, this enlargement being pierced by the oblong hole e through which the
shank A passes.
The width of the hole c is such that the shank A will
fit easily therein and the hole is made long enough to allow of the arms
falling a-trip at either side of the shank. D is the joint pin which secures the
head B and the shank A together and which projects at each side of the shank and
fits into recesses e, e in the underside of the head at each side of the hole c therein;
and are the two plates which cover the recesses and are each secured to the
head by the two screw bolts y', g', (or screws or rivets may be used) thus securing the
head to the projecting parts of the pin. By removing the screws g', gand
the plates the head will be free from the joint pin and can be moved up the
shank (see Fig. 6); the joint pin can then be removed and, when one or other of the
shackles i, j on the ends of the shank have been removed therefrom, the shank can be
withdrawn from the head. Fig. 2 shows how, when the arms are a-trip, the ends of
the oblong hole c in the side projections 1, 2 come into contact with the shank A
above and below the joint pin D thus forming stops for preventing the arms moving
through too large an angle, and to this end the ends of the hole are by preference
inclined so as to fit against the shank when the arms are a-trip on either side.
It will be obvious that various methods of securing the pin D in the recesses e¹, e
other than that illustrated by Figs. 1 to 6 both inclusive may be employed without
departing from the nature of this invention; as for instance the bolts instead of
being tapped into the head may pass right through and be secured by cottars and the
bolt heads may be countersunk into the plates so as to be flush therewith; or
as illustrated by Figs. 7, 8, and 9 the plates, may be altogether dispensed with and
the pin D secured by two bolts which fit into holes formed at the ends of the recess e
and partly in the ends of the pin D; these pins are by preference formed with counter-
sunk heads and secured in the head by cottars. Or the pin D may be prevented froin
moving out of the recesses el, el, as shewn in the modification illustrated by Figs. 10, 11
and 12 in which a cross bolt is provided in the shank between the arms and adjacent
to the head against which the head bears, two projecting parts of the head, forming
ares of a circle of which the pin D is the centre, being forged on the head so as
always to bear against the pin K in whatever position the arms may be. The pin K is
by preference formed as shewn with a circular head on one side of the shank A
and a collar on the other side secured by a cottar 3; the projections 1, then bear
respectively against the head and the collar k².
It will be seen that the shape of the head B substantially as illustrated on the
drawings, admits of its being forged in a single piece of iron or steel without
a weld as this can be done by forging a lump, preferably of rectangular form, of about
the same thickness as the head and whilst in a heated state punching and working
the hole e and drawing down the arms &¹¹and leaving the projections & at either side.

page_text: Having now particularly described and ascertained the nature of our said Inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:
1st. Forging tripping anchor heads of the shape substantially as hereinbefore
described and illustrated by the accompanying drawings thereby enabling them to be
made weldless as set forth.
2nd. In an anchor and in combination, a forged tripping head of the shapo
substantially as shewn and described, a shank passing through the head and a joint
pin passing through the shank and projecting at each side thereof, the projecting
parts of the said joint pin fitting in recesses in the underside of the head and
being there secured in any of the ways substantially as hereinbefore described and
illustrated by the accompanying drawings.
