1, HENRY FRANKLIN HIRON of No. 16 Albemarle Stroet, Piccadilly in the County
of Middlesex, Gentleman do hereby declare the nature of this invention to be
as follows:-
My Invention relates to the class of Anchors in which the Crown Arms or Fluke
piece turns in the head of the Shank, such for instance as those known as Martins
Anchors, and consists of improvements in the construction and manufacture of such
Anchors whereby they are made easier and cheaper and their holding power strength
and efficiency is increased.
In carrying out my Invention the Crown Arms or Fluke piece are made on each
side close to the Shank head near the boss or Central axis with Iron or Steel Teeth
Plates which act as a lever on the Crown Arms or Fluke piece forcing them into the
ground. The Teeth Plates work independently of each other and are secured to the
Crown Arms or Fluke piece by means of Pins or Rivets, and for the purpose of
securing the Teeth Plates the Crown Arms or Fluke piece are made square on each
side near the boss or central axis.
In another improvement the Crown arms or Fluke piece are made on each side
between the boss or central axis and the palms with iron or steel bolts or bars passing
through the Crown Arms or Fluko piece which also act as a lever on the Crown Arins
or Fluke piece forcing them into the ground. The iron or steel bolts or bars are
made of the minimum size practicable so as not to weaken the Crown Arms or Fluke
piece which are made of increased thickness proportionately.
By constructing the Crown Arms or Fluke piece with the Iron or Steel Teeth
Plates or the Iron or Steel bolts or bars working independently of each other as
above described the Crown Arms or Fluke piece are forced to take hold of the
ground when the Anchor
in use.
The remaining parts of the Anchor or parts connected therewith are constructed in
the manner usual in Anchors of the class.

page_text: Improvements in Anchors.
J, HENRY FRANKLIN HIRON of No. 16 Albemarle Street, Piccadilly in the County
of Middlesex Gentleman 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 said Invention relates to the type or class of Anchor in which the Crown Arms
or fluke piece turns in the head of the shank such for instance as those known as
Martins Anchors, and consists of improvements in the construction and manufacture
of such Anchors whereby they are made easier, and cheaper and their holding power,
strength, durability and efficiency is increased."
In order that my Invention may be fully understood I shall now proceed more
particularly to describe the same and for that purpose shall refer to the several
Figures in the annexed sheet of Drawings the same letter of reference indicating
corresponding parts in all the figures.
"
One modification of my improved Anchor is shown on the Drawings. Figure "1"
is a side elevation. Figure "2" is a plan as at right angles to Figure 1-Figure "3
is a plan of the Teeth Plates.
In this modification the Crown Arms or fluke piece "A" are made or fitted on
each side at the part "B" close to the shank head "C" near to the boss or central
axis "D" with iron or steel Teeth Plates E which move with the Crown Arms or
fluke piece "A" acting as a lever and forcing the said Crown arms or fluke piece to
turn downwards, and to take hold of the ground. The Teeth Plates "E" work or
act independently of each other, they are secured to the Crown Arms or fluke piece
by means of a cross pin, rivet, bolt or key or in any other suitable way.
purpose of securing the said Teeth Plates the said Crown Arms or fluke piece are
inade square on each side at the part "B" near to the boss or central axis.
<<
For the
In another modification of my Improved Anchor as shown in the Drawings-
Figure 4" is a side elevation-Figure 5 is a Plan as at right angles to Figure 4.-
Figure 6 is a Plan of the Iron or Steel Bolts or bars.
In this modification the Crown Arms or fluke piece "A" are made or fitted on
each side at the part "F" between the boss or central axis and the palms of the said
Crown Arms or fluke piece with iron or steel bolts or bars "G" which pass through
the said Crown arms or fluke piece at the said part "F" and which said bolts or
bars move with the said Crown arms or fluke piece and act as a lever forcing the
said Crown arms or fluke piece to turn downwards and take hold of the ground.
The said bolts or bars "G" are made round with wedge shaped pointed ends, they
are made of the minimum diameter practicable proportionately to the size and weight
of the Anchor in order not to weaken the said Crown arms or fluke piece and which
said Crown arms or fluke piece are also made of the maximum thickness propor-
tionately to the size and weight of the Anchor. The said bolts or bars "G" are

page_text: secured in their place by means of a cross pin rivet or key or in any other
suitable way.
I construct the remaining parts of the said Anchors or parts connected therewith
in any suitable way usual in Anchors of the type or class and I do not bind myself
to the use of the Arms or Stock of the shape or to the using of any Stock at all as
the Anchors can be made with or without the Stock as may be required.
Having fully described my Invention and in what manner it is to be carried out
I now declare what I consider novel and original and what I claim is
1. The Improved construction of Anchors with the iron or steel Teeth Plates as
shown in Figures 1, 2, and 3 of the accompanying drawings and hereinbefore
described.
2. The Improved construction of Anchors with the iron or steel Bolts or
Bars as shown in Figures 4, 5 and 6 of the accompanying Drawings and herein before
described.
3. The arrangement and combination of parts constituting the Anchors hereinbefore
described and illustrated in the accompanying Drawings.
