PROVISIONAL SPECIFICATION.
Improvements in Anchors.
1, THOMAS FLEWETT CHADDOCK of 9 Park Villas, Charlton Road, Blackheath, in
the County of Kent, Engineer do hereby declare the nature of this invention to be
as follows:
"
This invention has reference to improvements in what are known as Stockless
Anchors" and consists in forming the whole head, namely, the two flukes, the joint pin
or part, on which the head turns, and the side, projections or ribs necessary to cause
the anchor head to trip, as a single casting, and attaching the shank thereto by any
suitable method, such for instance as passing a strap round the said pin or part and
securing the strap to the shank by bolts or cotters.
It is not essential to use two flukes, a greater or less number may be employed
when desired, and in certain cases the tripping projections or ribs may be dispensed
with entirely or in part.

COMPLETE SPECIFICATION.
Improvements in Anchors.
I THOMAS FLEWETT CRADDOCK of 9 Park Villas Charlton Road Blackheath in
the County of Kent Engineer 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 :-
11
My Invention has reference to what are known as stockless anchors and consists in
forming the whole head namely, the fluke or flukes, the joint pin or part on which
the head turns and the projections ridges or ribs which cause the head to "trip" as a
single casting and attaching the shank thereto in any suitable manner such for
instance as by passing a strap round the said pin or part and securing the said strap
or shank by bolts or cotters.
The accompanying drawings will shew clearly the manner in which my 'Invention
may be carried into effect.
Figure 1 is a plan and Figure 2 is a side elevation of an anchor made according
to my Invention with the two flukes lying in the same plane as the shank. Figure
is a central longitudinal section through the shank and bead with the flukes tripped
in the position which they occupy when the anchor is in use.
The flukes A B, the projections ridges or ribs CD and E F which cause the
head to trip when the anchor is laid on the ground and the pin G are cast together
in one piece. Round the pin or pivot G I pass a strap H which I secure to the
shank J by means of rivets K L, the hole through the head necessary to admit the
strap being formed with inclined faces M N and OP which bear against the strap
and hold the flukes at the desired angle on either side of the shank when the anchor
has hold of the ground.
The form of the tripping projections ridges or ribs may be modified in various
ways or may be extended so as to form one or more additional flukes on each side of
the head if desired but the shape shown on the drawings is that which I prefer. I
do not limit myself to the precise mode which I have shewn and described of
attaching the head to the shank as it may be done in any suitable way, but the
means shewn on the drawings I consider most convenient and suitable. I have
shewn two flukes but 1 may use one or more than two if desired and the projections
ridges or ribs C D E F may be dispensed with in whole or in part if desired.

page_text: Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed I declare that what I
claim is..
In what are known as Stockless Anchors a head with all its parts or members
cast in.one picce substantially as hereinbefore described and illustrated.
