Complete Specification Accepted, 9th Mar., 1889
We, JOHN FRANCIS HALL of Norbury Sheffield, Manager of Steel Works, and JOHN
VERITY of Billing Bank, Bramley near Leeds, Engineer, both in the County of York,
do hereby declare the nature of this invention, to be as follows:-
Our invention consists in certain improvements in anchors whereby they are
rendered more efficient and certain in their action and less liable to drag or roll over
than hitherto, and has reference to a patent granted to us dated 11th day of March
1886, No. 3461.
According to our invention we make the arms or flukes and horns or trippers in
one piece, such horns or trippers being arranged in front of the centre of the axis of
the crosshead.
The crosshead is hollowed out for the reception of trunnions of the shank; these
trunnions are not made in one piece with the shank but consist of a tube passed
through an eye or opening in the head of the shank when such head is in a heated
state, and when cold holds such trunnions firmly by shrinkage.
We extend or prolong the trippers the full width of the flukes, these thereby
serving the purpose of a stock bar.
The crown of the crosshead is recessed to receive the trunnions of the shank, and
is rounded or arched at suitable points in its length, also the extremities of such
crown are projected laterally therefrom, so that with these combined arrangements
the anchor on being dropped overboard will fall into position immediately on reaching
the ground.
A bolt or pin being passed through the arched or rounded pieces and trunnions
retains the shank in position between the arms or flukes, at the same time allowing a
radial movement of the shank and arms or flukes to any required extent.

Improvements in the Construction of Anchors.
We, JOHN FRANCIS HALL of Norbury, Pitsmoor, Sheffield, Manager of Steel
Works, and JOHN VERITY of Billing Bank, Bramley, near Leeds, Engineer, both in
the County of York, 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:-.
Our invention consists in certain improvements in anchors whereby they are
rendered more efficient and certain in their action and less liable to drag or roll over
than hitherto, and has reference to a Patent granted to us dated 11th day of March
1886 No. 3461.
In the accompanying drawings Fig. 1 is a front elevation. Fig. 2 a side elevation
and Fig. 3 a plan looking at the top of anchor, shewing our improvements.
According to our invention we make the arms or flukes A and horns or trippers B
in one piece, such horns or trippers B being arranged in front of the centre of the
axis of the crosshead C.
The crosshead C is hollowed out for the reception of the trunnions D of the
shank E, these trunnions D are not made in one piece with the shank E, but consist
of a tube passed through an eye or opening in the head of the shank E when such
head is in a heated state, and when cold holds such trunnions firmly by shrinkage.
We extend or prolong the trippers B the full width of the flukes A, these thereby
serving the purpose of a stock bar.
The crown of the crosshead is recessed to receive the trunnions D of the shank E,
and is rounded or arched at suitable points F in its length, also the extremities G of
such crown are projected laterally therefrom, so that by these combined arrangements
the anchor on being dropped overboard will fall into position immediately on reaching
the ground.
A bolt or pin H being passed through the arched or rounded pieces F and
trunnions D retains the shank in position between the arms or flukes A, at the same
time allowing a radial movement of the shank E and arms or flakes A to any required
extent.
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. The arrangement, construction and combination of flukes A with horns or
trippers B, such horns or trippers B being arranged in front of the centre of the axis
of the crosshead C, substantially as and for purposes herein set forth.

page_text: 2nd. The arrangement, and application of trunnions D, consisting of a tube, such
tube being inserted into the eye in the head of the shank E whilst such head is in a
heated state, so that when cold the trunnions are held firmly in position by shrinkage,
substantially as herein set forth.
3rd. The arrangement, construction and application of trippers B, extending the
full width of the flukes A, and serving the purpose of a stock bar, substantially as
herein set forth.
4th. The combination of the various parts forming the anchor, substantially as and
for purposes herein set forth.
