PROVISIONAL SPECIFICATION.
Improvements in Ships' Anchors.
I. ANDREW ANDERSON of No. 19 Erskine Road, South Shields, in the County
of Durham, Master Mariner, do hereby declare the nature of my invention to be
as follows:
My invention relates to improvements in ships' anchors, and its objects are to
provide for the stock folding down against the shank as the latter is drawn into the
hawse pipe, and being opened outwards into the normal position of an anchor stock
by the weight of the anchor during the time that the latter is being dropped..
Further, it relates to improved tripping devices adapted to set the flukes in the
best position for being pulled into the bottom.
In carrying the invention into effect the half stocks are pivotted to the respective
sides of the shank and connected by links to a bolt or equivalent device which is
passed through or adapted to engage with a link or shackle on the end of the shank.
So that as the weight of the anchor pulls upon the said shackle the half stocks will
be pulled up and outwards from the shank into the operative position, and when
the anchor is being hauled in, the said half stocks will yield to the mouth of the
hawse pipe and be by it closed down alongside the shank. The palms are pivotted
to the head and there is provision made for their being brought into a direct line
with i.e. close up to the shank, but not close enough to risk the chance of fouling.
Suitable projections also are formed on the anchor-head which projections must be,
in respect of position, contour and size, adapted to trip the palms into their
respective operative positions. There is also provided for or in combination with
the palms above mentioned a projection of a contour adapted to assist in the act of
tripping them, to the extent that when the anchor head is lying on the ground the
pull on the cable shall raise the shank and therefore provide for the palms being in
the best possible position for entering the bottom.

COMPLETE SPECIFICATION.
Improvements in Ships' Anchors.
I, ANDREW ANDERSON, of No. 19, Erskine Road, South Shields, in the County
of Durham, Master Mariner, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
My invention relates to improvements in ships' anchors and its objects are to
provide for the stock folding down against the shank as the latter is drawn into the
hawse pipe, and being opened outwards into the normal position by the weight of
the anchor as it is being dropped. Further, it relates to improved tripping devices
adapted to set the flukes in the best position for being pulled into the bottom.
In carrying the invention into effect, the half-stocks are pivotted to the respective
sides of the shank and connected by links to a bolt, or equivalent device, which is
passed through, or adapted to engage with, a link or shackle on the end of the
shank. So that as the weight of the anchor pulls upon the said shackle, the half-
stocks will be pulled up and outwards from the shank into the operative position,
and when the anchor is being hauled in, the said half-stocks will yield to the mouth.
of the hawse-pipe and be, by it, closed down alongside the shank. The palms are

page_text: pivotted to the head, and there is provision made for their being brought into a
direct line with-i.e. close up to, the shank, but not close enough to risk the chance
of fouling. Suitable projections also are formed on the anchor-head which
projections must be, in respect of position, contour, and size, adapted to trip the
palms into their respective operative positions. There is also provided for, or in
combination with, the palms above mentioned, a projection of a contour adapted to
assist in the act of tripping them, to the extent that when the anchor-head is lying
on the ground, the pull on the cable shall raise the shank, and therefore provide
for the palms being in the best possible position for entering the bottom.
In order that the invention and the means by which it is to be carried into
practical effect may be thoroughly understood, I will now describe them in detail,
referring in so doing to the accompanying drawings which are to be taken as part
of this Specification and read therewith.
Fig. illustrates the extensibility of the stock when made according to my
invention.
Fig. 2 is a side elevation of my improved anchor showing the half stocks in the
position they occupy when they are in the hawse-hole.
It should be pointed out that up to the present time all anchors made in such a
way that the shanks could enter the hawse hole have been stockless, for the obvious
reason that the presence of the stock joined to the shank in the rigid way hitherto
followed would prevent any such cutrance.
a is the anchor shank. It has the usual eye in its outer end, and in addition
thereto has two more, one on each side of it, formed in suitable lateral extensions b.
These two extensions with the end of the shank have an outline very similar to that
of a trefoil.
is a long shackle bolted to an eye in the end of the shank.
d, d are the two half stocks. Each half stock is pivotted upon, or to, its
respective extension. Both half stocks are in the same plane in order that when
they are in their operative position, i.e., at right angles with the shank, they shall
be aligned with each other and so constitute the anchor-stock. These half stocks
are preferably flat bars instead of being round or square in cross section as
heretofore.
e, e are extensions on the back or top of the half stocks, each one at a short
distance from the pivot of its respective half stock; and in each extension an eye
is formed, both eyes being at the same distance from the respective fulcra of the
half stocks.
are shackles respectively bolted to the extensions e, e. They are connected
by links g, to a bolt which passes through both top links g, and the shackle c.
is a shackle by which the junction between the cable j and the anchor is effected.
When the anchor is dropped, its weight pulling through the shackles and the
links g, puts the two half stocks into their operative position. On the other hand,
after the anchor has been hove up, the capstan still being kept at work, the two
half-stocks are turned down on their respective fulcra against the shank, and the
latter with them pulled into the hawse-pipe.
jare the two palms. Each one as. close to the shank as is consistent with
immunity from the risk of fouling. The object in setting the palms so close to the
shank is to bring them, or, what is practically the same thing, their grip of the
bottom, as nearly in the line of pull on the part of the cable, as possible.
l
k is a bolt or pin passed through both palms and the head of the shank. It is
this bolt which serves as the pivot upon which the palms move. 1, are trips.
These are made in one piece with, or otherwise joined to, the palms, and their
function is to cant the palms when the pull is on the cable, so as to bring their
noses into the best position for entering and holding to the bottom; and, for the
purpose of preventing the palms being canted too far, there is formed on the head
of the shank any suitable stop against which the palms bear, and which therefore
stops them when the trips have canted them into the said best position.
m is a projection from the head, and its object is to facilitate the tripping of the.

page_text: palms. In virtue of its position, it will be the first part of the anchor to reach the
bottom, and consequently will assist in canting the palms.
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 :-
1. The combination with an anchor-shank of two half stocks pivotted thereto and
adapted to be folded down alongside thereof, as set forth.
2. The combination of anchor-shank, two half stocks pivotted thereto. cable and
links and shackles by which the said half stocks are operated, as set forth.
3. The combination of shank, palms close up thereto and trips, as set forth.
4. The combination of shank, palms close up thereto, trips and projection from
the head adapted to assist in canting the palms, as set forth.
