Complete Specification Left, 15th Dec., 1896-Accepted, 13th Feb., 1897
I, EDGAR DARBY of Oulton Broad Lowestoft Suffolk Blacksmith do hereby
declare the nature of this invention to be as follows:-
The object of this invention is to provide a form of anchor which while offering
an efficient means of holding on to the ground, can. be readily folded up so as to be
easily stowed away when not required.
In order to carry out this invention I form the anchor with any required number
of flukes or arms and I arrange that these flukes or arms shall be jointed or hinged
at their inner ends, to the crown or end of the shank and radiating from it in a
manner similar to the ribs of an umbrella. I also form & place on the shank a
loose bush or sleeve suitably shaped, which is free to slide along the shank.
When the anchor is required to be used I arrange that this sleeve shall be pressed
down towards the crown or end of the shank where the flukes are jointed so that
the end of the sleeve which is made in a suitable form, shall press firmly against
the flukes, and keep them fully spread open so that they will readily enter the
ground. Where the anchor is not in use, or required to be stowed away,
I withdraw this sleeve from the position above described, sufficiently far along the
shank as to allow the flukes or arms to fold up closely to the shank in a similar
manner to the ribs of an umbrella when closed. The points of the flukes will then
be in contact or nearly so with the body of the shank and I arrange the form of
the loose sleeve above referred to, so that it can slide on to the ends or points of the
flukes, or engage them in slots in such a manner as to hold them rigidly in the
closed position. To hold the sleeve in either of the positions required, viz. for
keeping the anchor open for use, or closed for stowage I form a wedge shaped
block on the shank of the anchor with a corresponding slot in the sleeve & by a
partial rotation of the sleeve I lock it firmly in position required, or I may use a
cotter with slots in the sleeve & shank so the cotter will hold the sleeve in the
positions required, or I may use either of the means described above to hold the
sleeve against the arms or flukes and a spring or other suitable means to keep
the sleeve engaged on the flukes when closed. The anchors herein referred to
are to be used either with or without stocks.

Improvements in Anchors.
I, EDGAR DARBY, of Oulton Broad, Lowestoft, in the County of Suffolk,
Blacksmith, 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 :-
This invention relates to anchors, and consists in an improved form of anchor
which, while offering an efficient means of holding on to the ground, can be readily
folded up, so as to be easily stowed away in a small compass when not required
for use

page_text: In order that this invention may be fully understood and ascertained I append
drawings in which :--
Fig. 1 is an elevation of an anchor according to my invention, open.
Fig. 2 is an elevation of same, closed.
Figs. 3, 4, 5 and 6 are detail views on an enlarged scale.
A indicates an anchor shank and B the flukes or arins, of which there may be
any convenient number, three being shewn arranged at angles of 120° to each other.
The hinged end b of each of these is pivoted to lugs or projections a which are
either formed integrally with or rigidly attached to one end of the anchor shank A;
the flukes or arms B being thus free to be moved on the pins a' so as to allow them
either to be folded up as shewn in Fig. 2, or opened as shewn in Fig. 1. a* is a
shackle to which a rope or cable may be attached, and a stock S may be used as
shewn in dotted lines in Figs. 1 and 2. a' is a ring to which a rope may be
attached and used for the purpose of clearing the anchor.
An anchor as thus described contains no novel features, and this invention
consists in means for holding the flukes in either of the positions shewn in Figs. 1
and 2.
Upon the shank of the anchor I form two wedge shaped blocks or pr
jections, C which is situate just above the points of the flukes or arms B when
these are closed, and D which is situate close to the lugs a. Fitting loosely so as
to slide freely upon the shank A is a bush E which has the form of a hollow
truncated cone with an inside flange e at its bottom. This bush has a groove el
formed inside it near its upper end, of such a depth as to allow the bush to slide
over the projection or lug C when the bush is turned so as to bring the groove e¹
coincident with the projection C. A groove ex is formed in the flange e coincident
with the grove e'. The flange e is cupped underneath and is of such a bore as to
enable the bush to slide and turn freely on the shank, but the bush cannot pass the
projections C or D except when the grooves e and ex are placed in a line with the
projections. The upper part of the groove e cuts through the bush and forms a
notch, and the flange e has a notch in line with e. The upper edge of the bush
has a projection & formed upon it which acts as a stop for a purpose to be herein-
after described.
If the anchor flukes are folded with their points held by the bush as shewn in
Fig. 2 and it is desired to open them, it is necessary only to turn the bush round
until the notch and groove e' coincide and come in a line with the projection C
as shewn in Fig. 4, when the bush E can be lifted sufficiently far to release the
flukes B and allow them to fall .until they assume the positions shewn in Fig. 1.
The bush also can then be allowed to fall until the notch or groove e* in the
flange e passes over the projection D, when the bush being turned, the unbroken
part of the flange e engages the projection D which retain the flange e, bush D and
Hlukes B in the open position.
The anchor is thus in condition for use, and when it becomes necessary to fold
the flukes so that the anchor may be stowed, it is necessary only to turn the bush E
in the opposite direction from that of the previous movement, and thus bring the
notch and grooves e and ex again in a line with the projections D and C, when
the bush can be lifted up so as to pass these projections; the flukes B can then be
folded up to the position shewn in Fig. 2 and the bush dropped upon it so that the
cupped part of the flange e holds the points of the flukes. The turning of the
bush E to the position shewn in Figs. 2 and 3 then holds the whole tightly together
for convenient stowage. The projection prevents the bush making a complete
rotation.
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. An improved anchor, the flukes of which can be folded and held in position
LL
L
the shank of the anabor so of either

page_text: to be held in one of two positions or left free to move longitudinally upon the
shank, substantially as described and shewn.
2. In an anchor, the combination of a shank having two projections upon it, one
or more folding flukes pivoted to the lower end of the shank, and a bush having a
flange and two notches or grooves cut in its bore, and capable of being turned upon
the shank, so as either to fix the flakes open or closed, or to slide longitudinally
upon the shank so as to free the flukes, substantially as shewn and described.
3. In an anchor, the combination of the shank A, the pivoted flukes B, the
projections C and D, and the bush E having a flange e, notches or grooves e and e*,
and a projection, substantially as shewn and described.
4. An improved anchor substantially as shewu and described with reference to
the accompanying drawings.
