page_text: I, Stanley Charles Paul, of 2, Park Villas, Old Swinford, Stourbridge, in
the County of Worcester, Mechanical Engineer, do hereby declare the nature
of this invention to be as follows:-
This invention has reference to those stockless and other anchors in which
the head with its two arms are made in one piece and arranged to trip to either
side of the shank, and this invention consists of the herein described improved
construction of the head and shank whereby they are so connected together
that the head trips very freely and is therefore certain in action and stones and.
mud are effectually prevented from entering and choking the recess in the head
where the shank works. Moreover the head and shank cannot possibly become
detached in use unless one of them breaks.
In carrying out this invention the centre of the head is made with a large
sector like recess or hole to receive the shank, this hole passing right through
the head from the back to the front thereof and being made of such a width
as to allow the shank to work freely therein. This sector is struck from a
centre betewen the arms and is in a plane at right angles thereto, the terminations
of the sector forming stops to limit the trip movement of the shank, that is
to say, these terminations cach make an angle of about 42° with the centre
line of the arms.
The end of the shank which fits in the recess in the head is
formed with a projection at each side which take against shoulders or rebates
formed in the sides of the sector like recess so that the pull of the anchor is taken
by these projections of the shank bearing against the said shoulders or rebates.
The hole in the head through which the shank passes has to be made just sufficiently
large to allow of the head tripping to the proper angle say to about 42° and
when in this position the further turning movement of the shank is prevented by
the shank coming against the end of the sector like hole and against a shoulder
formed at the front of the head and which is the termination of the other end of
the sector like hole.
In putting the anchor together the shank has to be threaded through the hole
in the head from the crown of the head as will readily be understood and the head
and shank are kept together by one or more curved plates rivetted or otherwise
fixed to the crown of the head so as to close the larger opening of the sector
like recess in the head.
.
It will be seen that directly the anchor is a-trip the turning of the shank
effectually closes the hole in the front part of the head and thus prevents any
mud or stones entering the sector like hole so that there is no danger of the
anchor becoming clogged. Even if any mud should enter the sector like recess
before the front is closed by the shank such mud would be swilled out through
the crown where a suitable hole or holes is or are or may be provided in the
curved plate for that purpose. :

I, STANLEY CHARLES PAUL, of 2, Park Villas, Old Swinford, Stourbridge, in
the County of Worcester, Mechanical Engineer, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be parti-
cularly described and ascertained in and by the following statement:-
This invention has reference to those stockless and other, anchors in which
the head with its two arms are made in one piece and arranged to trip to either
side of the shank, and this invention consists of the herein described improved
construction of the head and shank whereby they are so connected together
that the head trips very freely and is therefore certain in action and stones and
mud are effectually prevented from entering and choking the recess in the head
where the shank works. Moreover the head and shank cannot possibly become
detached in use unless one of then breaks.
I will describe my invention by referring to the accompanying drawing on
which Fig. 1 is a front clevation of an anchor constructed according to this
invention Fig. 2 is a part sectional elevation of the same; Fig. 3 is a cross
sectional élevation of the head with the shank broken off; Fig. 4 is an inverted
plan partly in section; Fig. 5 is a similar view to Fig. 3 but with the head
and arms a-trip; Fig. 6 is a separate view of the end part of the shank which
works in the head; and Fig. 7 is an inverted plan partly in section and illus-
trating a slight modification of my invention.
The same letters of reference indicate the same parts in all the figures.
In carrying out this invention the centre part of the head A is made with a
large sector like recess or hole B to receive the shank C which latter is of rect-
angular shape in cross section and fits easily between the sides 12 of the hole B
which passes right through the head from the back 63 to the front thereof
the width of the hole B being such as to allow the shank C to work properly
therein. This sector like recess B is struck from a centre d (see Figs. 3 and 5)
between the arms a¹ a² and is in a plane at right angles thereto, the termina-
tions 65 of the sector like hole B forming stops to limit the trip movement of
the head,, that is to say, these terminations 65 66 each make an angle of about 42°
with the centre line cc of the arms a¹ a². The end of the, shank which fits in
the recess B is formed with projections el at each side which take against
shoulders or rebates 67 68 formed in the sides 61 62 of the sector like, recess B so
that the pull of the anchor is taken by these projections cc of the shank bearing
against the shoulders or rebates 67 68. The projecting parts c¹ c² are curved (as
shewn in Fig. 6) so as to fit against the rebates 67 68. The hole B in the head A
through which the shank C passes, has to be made just sufficiently large enough
to allow of the head tripping to the proper angle, say to about 42° as, shewn in
Fig. 5 and when in this position the further turning movement of the head
is prevented by the shank coming against the end 66 of the sector like hole and
against a shoulder 69 formed at the front of the head at the termination of the
other end of the sector like hole A. There is a shoulder, 610 at the opposite side
of the hole to 69 to form a stop for the shank when the head is a-trip at the
opposite side of the shank to that shewn in Fig. 5.
"

page_text: In putting the anchor together the shank C has to be threaded through the
hole B in the head A from the crown of the head as will readily be understood.
The head A and the shank C are kept together by the curved plate E which is
rivetted as by the rivets e¹ e²ee or otherwise fixed to the crown A of the head
so as to close the larger opening of the sector like recess in the head.
It will be seen by an examination of Fig. 5 that directly the anchor is a-trip
the turning of the head has effectually closed the hole B at the front part of
the head and has thus prevented any mud or stones from entering the hole A
so that there is no danger of the anchor becoming clogged. Even if any mud
should enter the sector like hole A before the front is closed by the shank such
mud would be swilled out from the crown where a suitable hole or holes such
as e is or may be provided in the curved plate E for that purpose.
Instead of the head and shank being kept together by the curved plate Eas
shewn in Figs. 1, 2, 3, 4 and 5 two curved plates such as E2 E3 may be used
for this purpose and rivetted or otherwise fixed to the underside of the head A
as in Fig. 7 so as to leave a narrow opening between them through which the
end of the shank C cannot pass.
It will be evident that my invention is applicable alike to stockless anchors
and to those anchors which are provided with a stock.
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-
-
In an anchor, the combination, of a shank made with side projections at its
lower end enclosed in the head, a tripping head provided with a sector like recess
which receives the shank the said recess having sector like rebates 67 68 which
take against said projections of the shank, the terminations of said recess forming
stops to limit the tripping movement of the head, and a cover plate or cover
plates fixed over the said recess to prevent the head from moving up the shank,
all substantially as set forth.
