I, ALEXANDER MELVILLE CLARK, of the firm of A. M. and Wm. Clark, of
53, Chancery Lane, in the County of Middlesex, Fellow of the Institute of Patent
Agents, do hereby declare the nature of the said Invention for AN IMPROVED
MEANS OF SUPPORTING, AND FACILITATING THE CASTING LOOSE OF, A VESSEL'S
ANCHOR a communication to me from abroad by Rufus P. Trefry of Bridgewater
in the Colony of Nova Scotia to be as follows:-
The object of this invention is to provide a means of holding an anchor by the
fluke, the stock of the anchor coming against the hull of the vessel, and of
facilitating the casting loose of the anchor so that there is no danger of fouling.
And it consists of a casting in the form of an angular plate adapted to be bolted on
the rail of the vessel and having formed in its outer surface a cavity having an
abrupt oblique rear surface or shoulder upon which the fluke of the anchor may
rest in such position that the lower end of the stock comes against the hull of the
vessel. In front of this diagonal shoulder the recess or cavity is bevelled or con-
caved so as to act as a cam in letting go the anchor, and thereby to throw the
upper fluke clear of the hull and at same time cause the lower end of the stock to
bug the hull so that it can in no manner foul the cable. A hook is attached to the
cat-head to receive the catfall so that after the latter is made fast there will be no
endwise movement of the anchor which will thus be held perfectly secure.

I, ALEXANDER MELVILLE CLARK, of the firm of A. M. and Wm. Clark, of
53, Chancery Lane, in the County of Middlesex, Fellow of the Institute of Patent
Agents, do hereby declare the nature of the said Invention for "AN IMPROVED
MEANS OF SUPPORTING AND FACILITATING THE CASTING LOOSE OF A VESSEL'S
ANCHOR (a communication to me from abroad by Rufus P. Trefry of Bridgewater,
in the Colony of Nova Scotia, and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement:-
"
The object of this Invention is to provide a means of holding an anchor by the
fluke so that the stock of the anchor shall come against the hull of the vessel, and
of facilitating the casting loose of the anchor so that there is no danger of fouling.
Reference is to be had to the accompanying drawing forming part of this
specification in which similar letters of reference indicate corresponding parts in
both figures.
Figure 1 is a perspective view of a vessel's bow with the device of this Invention
applied to the rail thereof the anchor being supported thereby. Figure 2 is a
perspective view of the device separately.
The device consists of a casting A preferably of the angular form shown at a so
as to be adapted to be placed on the rail of the vessel and secured by bolts or
heavy spikes passed through holes b. In the outer surface is formed a cavity
having an abrupt oblique rear surface or shoulder c upon which, (after the anchor
has been raised to the cathead E and secured by the cat fall F) the fluke d of the
anchor may be placed and rest in such position that the lower end of the stock D
comes against the hull C of the vessel as shown in figure 1. In front of this
diagonal shoulder c the recess or cavity is bevelled or concaved as shown at e so as
to act as a cam in letting go the anchor, and thereby to throw the upper fluke d
clear of the hull and at same time cause the lower end of the stock D to hug the
bull so that it can in no manner foul the cable G. A hook fis attached to the cat-
head to receive the catfall F so that after the latter is made fast to the cleat
there will be no endwise movement of the anchor which will thus be held perfectly
secure.
Having now particularly described and ascertained the nature of the said
Invention and in what manner the same is to be performed, I declare that what
I claim is
1st In a device for supporting, and facilitating the casting loose of, and anchor,
the angular plate provided with a cavity or recess extending across said plate, and
having an abrupt oblique rear surface, substantially as, and for the purpose set
forth.
2nd In a device for supporting, and facilitating the casting loose of, an anchor,
the plate having an oblique or diagonal shoulder or flange crossing the plate from
side to side, the base of said shoulder or flange touching a sloping or inclined
surface of said plate substantially as and for the purpose set forth.

page_text: 3rd In a device for supporting, and facilitating the casting loose of, an anchor,
the plate having an oblique shoulder or flange extending transversely from side to
side of said plate, said plate also having a cavity or concavity in front of said
shoulder or flange substantially as and for the purpose specified.
