PROVISIONAI. SPECIFICATION.
A New or Improved Ship's Anchor.
I JAMES BLACKWOOD NOBLE, of The Crown Works, Northam, in the Town
and County of the Town of Southampton, Engineer do hereby declare the nature
of this invention to be as follows:-
My invention relates to anchors.
The main object of my said invention is to provide an anchor of simple
construction but with great holding power.
In making an anchor according to one form or modification of my invention, the
shank is formed with a forked head through which is passed a spindle or shaft the
ends of same projecting beyond the sides of the forked head. Upon the projecting
ends the main arms which are formed with fluke ends-are fitted and secured,
one on each side, and in a direction lengthways of and parallel, or approximately
so, to the sides of the shank and ou the outer end of the shaft I mount and fix V, or
U shaped auxiliary arms with fluke ends, which are fitted at an approved angle to
the main arms, the auxiliary arms serve to trip the main arms and also add to the
gripping power of the anchor.
Upon the shaft, and between the jaws of forked head I fit a cross bar, and the
circular motion of the shaft in its bearings in the forked head of shank-and
therefore the angle to the shank at which the main arms can be opened out-is
limited by one of the free ends of said cross bar coming in contact with the top
part of the shank when the arms are gripping.
I may form an eye upon the extremity of the free ends of the aforesaid cross bar
and when the anchor is being stowed the "fish" tackle will be connected to one of
the said eyes for the purpose of fishing the anchor.
Dated this 13th day of May 1893.

COMPLETE SPECIFICATION.
A New or Improved Ship's Anchor.
1, JAMES BLACKWOOD NOBLE, of The Crown Works, Northam, in the Town
and County of the Town of Southampton, Engineer, 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 :-
My invention has for its object to provide a ship's anchor of simple construction
with great holding power. The shank is formed with a forked head through which
is passed a spindle or shaft the ends of same projecting beyond the sides of the
forked head. Upon the projecting ends the main arms which are formed with
fluke ends are fitted and secured, one on each side and in a direction lengthways of
and parallel or approximately so to the sides of the shank and on the outer end of
the shaft I mount and fix V or U shaped auxiliary arms with fluke ends, which are
fitted at an approved angle to the main arms; the auxiliary arms serve to trip the
main arms and also add to the gripping power of the anchor.
Upon the shaft and between the jaws of the forked head I fit a cross bar and
the circular motion of the shaft in its bearing in the forked head of shauk-and

page_text: therefore the angle to the shank at which the main arms can be opened out-is
limited by one of the free ends of said cross bar coming in contact with the top part
of the shank when the arms are gripping.
I may form an eye upon the extremity of the free ends of the aforesaid cross bar
and when the anchor is being stowed the "fish" tackle will be connected to one of
the said eyes for the purpose of fishing the anchor. Such an anchor is shown in
two elevations at right angles to one another by Figs. 1 and 2 and in end elevation
by Fig. 3 of the accompanying drawings. 1 is the shank; 2, 2, are the jaws of its
forked head; 3 is the spindle or shaft; it is of rectangular cross section with the
angles slightly rounded and passes through (so as to be able to partially rotate
within) holes in the jaws 2, and its ends which are squared project beyond the
jaws. 4, 4 are main arms with fluke ends, one such arm being fitted and shewn on
each projecting end of the spindle. 5, 5 are auxiliary arms of V-shape with
flukes one of these arms is fitted and secured on to each end of the spindle. The
auxiliary arms serve to trip the main arms and add to the gripping power of the
anchor. The main and auxiliary arms which are made with rectangular holes to
fit upon rectangular portions of the spindle are kept in place by means of nuts 6
and lock nuts 6 which are screwed upon the threaded extremities of the shaft.
7 is a cross bar fitted and fixed between the jaws 2 upon the spindle shaft 3
which is flattened on one side to prevent the cross bar turning thereon. One or
other of the free ends of this cross bar by coming in contact with the head 2 limits
the movement of the spindle and arms in either direction about the axis of the
spindle.
8, 8 are eyes formed in the ends of the cross bar 7; they enable fish tackle to
be connected for fishing the anchor.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare, having made
application for Letters Patent No. 8986 of the year 1893 for "Improvements in
and relating to Grapnels or Anchors Specially Designed for Marine Life-saving
but Adapted for other Purposes as a Grapnel or Anchor," I do not herein claim
anything claimed in the Specification of my aforesaid application but that what I
do claim is :-
My hereinabove described improved ship's anchor with shank, forked head,
spindle or shaft extending through holes in the jaws of said forked head main
arms 4 and auxiliary arms 5 secured on the respective ends of said spindle or shaft
outside of the forked head and a cross bar secured on the shaft or spindle between
the said jaws as set forth and illustrated.
