Wo HENRY PERSHOUSE PARKES of Tipton Green Chain and Anchor Works
Tipton in the County of Stafford Chain and Anchor Manufacturer and JOHN
GEORGE RITSON HARTNESS of No. 7 Elliot Street Felling in the County of Durham
Engineer do hereby declare the nature of this Invention to be as follows:-
Our invention has reference to the hawse pipes of ships and boats provided with
stockless anchors and consists of the improvements hereinafter described by which
improvements the storing of the anchor and the mooring of the ship or boat are
much facilitated.
A hawse pipe as ordinarily constructed consists of a single pipe or passage into
which when the anchor is raised and stowed the shank of the anchor passes the said
passage being wholly occupied by the shank of the raised anchor.
Our improvements consist in making the hawse pipe double that is making two
passages side by side or a broad passage divided into two passages by a partition.
In raising and stowing the anchor one of the said passages is occupied by the shank
of the anchor but the other unoccupied passage is available for receiving the chain
or cable for mooring the ship or boat.
Instead of making the hawse pipe with two passages it may be made with three or
more passages or of one pipe sufficiently broad for division by two or more partitions
into three or more passages side by side one of which passages being occupied by
the shank of the anchor when the anchor is raised and stowed and the others free to
be used in the mooring of the ship or hoat.
We prefer to make the several passages of hawse pipes made according to our
invention open into one mouth or flange but we do not limit ourselves thereto as
each passage may open into an independent mouth or flange with the same effect.

We HENRY PERSHOUSE PARKES of Tipton Green Chain and Anchor Works
Tipton in the County of Stafford Chain and Anchor Manufacturer and JOHN GEORGE
RITSON HARTNESS of No. 7 Elliot Street Felling in the County of Durham
Engineer do hereby declare the nature of our invention and in what manner the
same is to be performed to be particularly described and ascertained in and by the
following stateinent :-
Our invention has reference to the hawse pipes of ships and boats provided with
stockless anchors and consists of the improvements hereinafter described, by which
improvements the storing of the anchor and the mooring of the ship or boat are
much facilitated.
A hawse pipe as ordinarily constructed consists of a single pipe or passage into
which when the anchor is raised and stowed the shank of the anchor passes, the said
passage being wholly occupied by the shank of the raised anchor.
Our improvements consist in making the hawse pipe double, that is, making two
passages side by side or a broad passage divided into two passages by a partition.
In raising and stowing the anchor, one of the said passages is occupied by the anchor
but the other unoccupied- passage is available for receiving the chain or cable for
mooring the ship or boat..

page_text: Instead of making the hawse pipe with two passages it may be made with three
or more passages, or of one pipe sufficiently broad for division by two or more
partitions into three or more passages side by side, one of which passages being
occupied by the shank of the anchor when the anchor is raised and stowed and the
others free to be used in the mooring of the ship or boat.
We prefer to make the several passages of hawse pipes made according to our
invention open into one mouth or flange but we do not limit ourselves thereto as
each passage may open into an independent mouth or flange with the same effect.
Figure of the accompanying Drawing represents in sido elevation, partly in
section; Figure 2 in plan and Figure 3 in end elevation the bow of a ship provided
with double hawse. pipes according to our invention; Figure 4 represents in elevation
and Figure 5 in section one of the double hawse pipes detached from the ship.
The same letters of reference indicate the same parts in the several Figures of the
Drawing.
Each of the double hawse pipes is marked a, b and the longitudinal division or
partition between the two passages or compartments of the double hawso pipe is
marked c.
The said compartments or passages a, b are preferably made of different
diameters, the lower passage or compartment a being of greater diameter than the
upper passage or compartment & as represented. The two passages a, b may open at
top into a single mouth or flange but each passage may be provided with an
independent mouth or flange as represented at d, d. The double hawse pipe a 6 may
be made in one casting but it may be made of two separate pieces joined together
side by side or parallel in any convenient way. In the larger compartment or
passage a of each of the double hawse pipes, the shank of the stockless anchor e
passes on raising and stowing the anchor as represented in the Drawing; and through
the other compartment or passage the chain or cable is passed for mooring the.
ship to the buoy g or other mooring. The raised and stowed anchors e e are secured
in their places in the hawse pipes by the chains and fastenings at h, h of the ordinary
kind. By the use of a double hawse pipe as represented the ship may be moored by
her cable or cables without the necessity of removing the anchor or anchors from the
hawse pipe or pipes which is necessary when hawse pipes of the ordinary kind are
used.
Instead of making two compartments or passages in the hawse pipe one above the
other as described and represented they may be made side by side and three or more
passages may be made in each hawse pipe, the said passages being either situated one
above the other or side by side. When the hawse pipe contains three or more
passages, the anchor shank is stowed in one of the said passages and the others are
available to be used in the mooring of the ship or for the stowing of another
anchor.
Our invention may be applied to hawse pipes for boats as well as for ships.
Having now particularly described and ascertained the nature of our inven-
tion and the manner in which the same is to be performed we declare that we
claim as our invention of "Improvements in the hawse pipes of ships and boats":-
Making the said hawse pipes with two or more parallel compartments or passages
the said pipes being made in one piece or in more than one piece, one of the said
compartments or passages of the double or compound hawse pipe being occupied by
the shank of the raised and stowed stockless anchor and the other compartment or
compartiments being available for receiving the chain or cable or chains or cables for
mooring the ship or boat or for stowing another .anchor substantially as hereinbefore
described and illustrated in the accompanying Drawing.
