AN IMPROVED ANCHOR
Year: 1884

page_text: I HUGH MOMINN GIBB of St Johns Newfoundland Merchant do hereby declare
the nature of my Invention for AN IMPROVED ANCHOR to be as follows:-
The object of my invention is to construct anchors in an improved manner, by
which cheapness, efficiency, simplicity and convenience in stowage are secured.
Instead of the ordinary shank in one piece, I construct the shank in two parts
meeting together at the shackle and extending outwards and apart from each other
at a considerable angle where the flukes are joined thereto-The two portions of
the shank thus form two sides of a triangle and are placed at such a distance apart
as to dispense with the ordinary arms. The flukes are hinged to the ends of the
two portions of the shank, one duke on each; and they are so fitted as to have a
range of about 90 degrees in their movements from one side to the other, equal to
about 45 degrees on each side. The inner ends of the flukes are fitted with spurs
or projections which act as stops to control the range of motion of the flukes and
also assist in causing the flukes to assume the necessary position for taking hold of
and penetrating the ground.
•
Rings may be placed at the inner ends of the shanks to assist in fishing and
stowing the anchor.
My improved anchor requires no stock as it cannot fail to lay hold of the ground
without such appliance.
When the anchor is stowed the flukes can be placed in line with the shanks and
thus it occupies very little space and projects only a very small distance from the
ships side.
Anchors constructed in accordance with my invention possess the maximum of
strength with the minimum of material and labour required in and for their.
production.

I HUGH MOMINN GIBB of St John's Newfoundland Merchant do hereby declare
the nature of my said Invention for AN IMPROVED ANCHOR and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement:
The object of my invention is to construct anchors in an improved manner, by
which cheapness, efficiency, simplicity and convenience in stowage are secured.
-Instead of the.ordinary_shank, in one piece, I construct the shank in two parts,
mecting-together-at-the-shackle_and_extending outwards and-apart-from-each-
other at a considerable angle where the flukes aro joined thereto. The two-
portions of the shank thus form two sides of a triangle, and are placed at such a
distance apart as to dispense with the ordinary arms. The flukes are hinged to
the ends of the two portions of the shank, one fluke on each; and they are so fitted
"as to have-a-range-of-about-90-degrees in their movements from one side to the
other, equal to about 45 degrees on each side.-The inner ends of the flukes are
fitted with spurs or projections, which act as stops-to-control-the range of motion
of the flukes, and also-assist.in causing the flukes to assume the necessary position
for taking hold of and penetrating the ground.
Rings may be placed at the inner ends of the shanks to‘assist in fishing and
stowing the anchor.
My improved anchor requires no stock, as it cannot fail to lay hold of the
ground without such appliance.
When the anchor is stowed, the flukes can be placed in line with the shanks,
and thus it occupies very little space and projects only a very small distance from
the ship's side.
Anchors constructed in accordance with my invention possess the maximum of
strength with the minimum of material and labour required in and for their
production.
And in order that my said invention may be clearly understood, reference is
hereby made to the accompanying drawings, in which similar letters of reference
indicate corresponding parts.
Fig: 1 is a perspective view of the anchor complete-Fig 2 is an elevation of the
same in the position which it assumes when it is hanging to the davits at the ship's
side; and Fig 3 is a partial view to explain the action of the flukes. a a are the
two portions of the shank, of a V form, the junction of a a at b forming the
shackle, to which the ring c is attached for receiving the end of the cable. d d aro
two sockets or jaws, through which pins e c are riveted, having rings ƒ ƒ for
convenience in fishing the anchor. The flukes gg are pivoted on the pins e upon
which they are capable of revolving about a quartor of a circle and in either
direction, as shown in Fig 3 at g'-When the anchor is fished, as shown in Fig 2,
the flukes gg hang perpendicularly-The extent of the travel of the flukes is
governed by the formation of the curved shoulders at h which come into contact
with the lower part of d at i and this may be varied to suit the service for which
the anchor may be required. The spurs cause the flukes g g to fall into their
proper position when the anchor is dropped and before it begins to "bite.”

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1. The manufacture and use of anchors having a V formed shank a a, shackle b
jaws d d pins e e and pivoting flukes 9 g, substantially as hereinbefore described,
and shewn on the drawings.
2. The manufacture and use of anchors having a V formed shank a a shackle b,
jaws d d pins e e pivoting flukes gg fitted with spurs g³ g³ severally operating
substantially as herein before described and shewn on the drawings.
3. In the construction of anchors of the description aforesaid, the cable ring c
and fishing ringaff, together or separately substantially as and for the purposes
hereinbefore described and shewn on the drawings.
