PROVISIONAL SPECIFICATION left by the said George Frederic
Chantrell at the Office of the Commissioners of Patents, with his
Petition, on the 15th August 1878.
I, GEORGE FREDERIC CHANTRELL, of Liverpool, in the County of
Lancaster, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN ANCHORS AND KEDGES FOR HOLDING AND SECURING SHIPS AND
OTHER FLOATING BODIES,” (a communication), to be as follows:-
An anchor or kedge, constructed according to this Invention consists
in forming the shank with a slot or provision to receive a swinging
fluke.
The end of the slotted portion of the shank forms the crown, which 'is
composed of two suitable bosses formed on each side of the slotted
portion of the shank, and at the end thereof.

page_text: The slot may be made parallel, triangular, or of suitable shape to
receive the swinging fluke.
The slot may terminate in a plain shank piece forming the stock or
shackle end of the shank. The shank is fitted with a single swinging
fluke. This fluke is fitted and works inside the slotted portion of the
shank, and is jointed thereto by a suitable bolt, which passes through
the bosses on the slotted end of the shank and a boss formed on the end
of the swinging fluke. The swinging fluke is fitted with horns or pro-
visions, which serve the double purpose of forming stops to the fluke
and drags or bighting pieces for opening the swinging fluke, so that the 1
palm of the swinging fluke will penetrate the ground. The slotted
portion of the shank is fitted with provisions on each side thereof to
prevent the cable or chain fouling, and to take it clear of the projecting.
horns on the swinging fluke. The projecting horns or provisions on the
swinging fluke form stops by coming into contact with the bottom or ]
crown end of the shank. _
The shackle end of the shank may be fitted with a suitable stock
running at right angles to the swinging fluke, and fixed in any form
now in use, or the stock may be placed at the crown end of the shank,
and take the place of the bolt on which the fluke swings.
In some instances the shank may be slotted right through at the end,
the end being built in to form the stop for the swinging fluke.
A modification consists in making the shank in the form of a triangle,
the apex forming the shackle end and the base the crown end, the fluke
swinging in the centre. The stock passes through the crown end,
and forms the bolt on which the fluke swings, the base serving as the
stop.

Letters Patent, bearing date the Fifteenth day of August, in the year of
our Lord One thousand eight hundred and seventy-three, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said George Frederic Chantrell, Her special
licence that I, the said George Frederic Chantrell, my executors, adminis-
trators, and assigns, or such others as I, the said George Frederic
Chantrell, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for
“IMPROVEMENTS IN ANCHORS AND KEDGES FOR HOLDING AND SECURING SHIPS AND
OTHER FLOATING BODIES," a communication to me from abroad by Herford
Edwin Hope, of Bombay, in the Dominion of British India, upon the
condition (amongst others) that I, the said George Frederic Chantrell,
my executors or administrators, by an instrument in writing under my,
or their, or one of their hands and seals, should particularly describe
and ascertain the nature of the said Invention, and in what manner
the same was to be performed, and cause the same to be filed in the
Great Seal Patent Office within six calendar months next and imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said George Frederio Ohantrell, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement :-
An anchor or kedge constructed according to this Invention consists
in forming the shank with a slot or 'provision to receive a swinging'
finke.
The end of the slotted portion of the shank forms the crown, which is
composed of two suitable bosses formed on each side of the slotted
portion of the shank, and at the end thereof.
The slot may be made parallel, triangular, or of suitable shape to
receive the swinging fluke.
The slot may terminate in a plain shank piece forming the stock or
-

page_text: shank, and is jointed thereto by a suitable bolt, which passes through
the bosses on the slotted end of the shank and a boss formed on the end.
of the swinging fluke. The swinging fluke is fitted with horns or pro-
visions, which serve the double purpose of forming stops to the fluke
and drags or bighting pieces for opening the swinging fluke, so that the ♬
palm of the swinging fluke will penetrate the ground. The slotted
portion of the shank is fitted with provisions on each side thereof to
prevent the cable or chain fouling, and to take it clear of the projecting
horns on the swinging fluke. The projecting horns or provisions on the
swinging fluke form stops by coming into contact with the bottom or 1
crown end of the shank.
The shackle end of the shank may be fitted with a suitable stock
running at right angles to the swinging fluke, and fixed in any form
now in use, or the stock may be placed at the crown end of the shank,
and take the place of the bolt on which the fluke swings.
-
In some instances the shank may be slotted right through at the end,
the end being built in to form the stop for the swinging fluke.
1
A modification consists in making the shank in the form of a triangle,
the apex forming the shackle end, and the base the crown end, the fluke
swinging in the centre. The stock passes through the crown end, and 2
forms the bolt on which the fluke swings, the base serving as the
stop.
The anchor may be fished by shackles through the horns of the
swinging fluke, or by a ring at the crown end.
The before-going being the nature of this Invention, I will now pro-
ceed to describe more in detail how the same may be carried out into
practical effect, and for. that purpose I have hereunto attached a Sheet
of Drawings marked with letters and figures of reference corresponding
with those in the following explanation. Like letters and figures are
used to denote similar parts throughout the various views.
Figure 1 is an elevation of an anchor or kedge constructed according
to this Invention; Figure 2 is a side view of same.
Figure 3 is a side elevation of swinging fluke.
Figure 4 is a side elevation of portion of swinging fluke.
Figure 5 shows different forms of palms of swinging fluke.

page_text: Figures 6, 7, 8, and 9 show modifications of this Invention with the
stock passing through the crown end of the shank.
Figures 10 and 11 show a modification of this Invention with the
shank slotted right through, and the stop formed by a bar fixed on each
side of the fluke.
Upon reference it will be seen that an anchor or kedge constructed
according to this Invention consists in forming the shank A with a
slot or provision B to receive a swinging fluke C. The end of the
slotted portion B of the shank A forms a crown D, which is composed
of two suitable bosses D³, D³, formed on each side of the slotted portion
of the shank.
The slot or provision B may be made as shown at Figure 1, or
parallel as shown at Figure 7, or triangular as shown at Figures 8
and 9, or of other suitable shape to receive the swinging fluke C.
The slotted portion or provision may terminate in a plain shank piece
forming the stock or shackle end of the shank. E, stook of anchor; F,
shackle for cable; G, pin; H, shackle at crown end for fishing anchor;
I, provisions or lugs on each side of shank to prevent the cable or chain
fouling, and to take it clear of the projecting horns on the swinging
fluke C. The swinging fluke O is fitted and works inside the slotted
portion of the shank B, and is jointed thereto by a suitable bolt K,
which passes through the bosses D¹, D³, and a boss L formed on the
swinging fluke C. The swinging fluke O is fitted with horns or pro-
visions M for the double purpose of forming a stop to the fluke by
coming in contact with the crown of the anchor D and drags or bighting
pieces for opening the swinging fluke, so that the palm N of the
swinging fluke. O will penetrate the ground. The stock of the anchor E
may be fitted at right angles-to-the-swinging fluke O, and at the cable
end of the shank, as shown at Figures 1 and-2, or the stock may be
fixed at the crown and D of the shank, and take the place of the bolt on
which the fluke O swings, as shown at Figures 6, 7, 8, and 9:
Referring to Figure 4, it will be seen that the swinging fluke O may be
caused to take any required angle from the shank-by altering the crown
of the fluke, as shown in dotted lines X, Y, Z.
i
Referring to Figure 5, O, P, R, R, S, T, show different forms of

page_text: palms to be used acccording to the purposes and places for which the
anchor is required.
Referring to Figure 9, a, a, shank in two pieces; b, stock for fluke to
swing on; c, palm of required form, and fluke crown of required angles;
ȧ, bolt on which crown of fluke rests.
Referring to Figures 10 and 11, it will be seen that the shank A is
slotted right through at the end, the stop being formed by a bar U fixed
on each horn of fluke O.
•
Referring to Figure 1*, it will be seen that the anchor is compact for
stowage.
Referring to Figure 2*, the anchor is shown with the fluke open.
The main advantages attendant upon this Invention are that anchors
so constructed are more easily stowed and more portable than those now
in use, and having but one fluke are much lighter than any anchor yet¸
made in proportion to the holding capability.
Having now fully described the nature of this Invention, and how
the same may be carried out into practical offect, what I claim as tho
Invention communicated to me by Herford Edwin Hope is,-
