page_text: I, JOSEPH WRIGHT of Tipton in the County of Stafford, Mechanical Engineer
do hereby declare the nature of this Invention to be as follows:-
My Invention relates to the class of anchors in which the crown arms or fluke
piece are or is made capable of turning in the head of the shank such for example
as those known as Martin's anchors and my Invention has for its object to provide
an anchor easier and cheaper to make and stronger and more efficient in use and
with a larger bearing surface for the arrestment of the arms at their proper
angle and capable of having larger flukes than is the case with anchors of this
class as hitherto made.
According to my Invention I make upon the anchor cross or the centre of
the crown arms or fluke piece a rib or projection extending the full width or
thickness of the eye or opening in the head of the shank through which the said
cross or fluke piece passes and in which it can move. In the said eye or opening
in the shank I make a recess or slot extending from side to side thereof to receive
the said rib or projection on the anchor cross. The said recess or slot is of sufficient
width to allow of the necessary movement of the crown arms or fluke piece and
I bolt or otherwise secure plates over each side of the head of the shank to cover
the end openings of the said recess at each side. I preferably cut away the inward
part at each end of the rib or projection on the anchor cross so that side strain is
brought on the said plates as near to the securing bolts or fastenings as possible.
I may construct the remaining parts of the anchors or parts connected therewith
in any suitable way usual in anchors of this class. The recess in the head of the
shank gives virtually such an enlargement of the eye or opening that larger flukes
can be used than hitherto as they can be passed through the extended space
afforded by the said eye or opening and recess combined.
Dated this 8th day of December 1885.

page_text: I JOSEPH WRIGHT of Tipton in the County of Stafford Mechanical 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 relates to the class of Anchors in which the crown arms or fluke
pieces are or is made capable of turning in the head of the shank such for example
as those known as Martin's Anchors and my Invention has for its object to provide
an Anchor easier and cheaper to make and stronger and more efficient in use and
with a larger bearing surface for the arrestment of the crown arms at their proper
angle and capable of having larger flukes on them than is the case with anchors
of this class as hitherto made.
I will describe with reference to the accompanying drawings an anchor made
according to my Invention Figure 1 is a plan partly in section-Figure 2 is a
side elevation and Figure 3 is a plan of the crown arms separately from the shank
part Figure 4 is a section on the line 1. 2 of Figure and Figure 5 is a section
of the head of the shank with the centre of the crown arms in position.
According to my Invention I make at the centre portion of the length of the
Anchor cross or crown arms or fluke piece A and on the inner side of the periphery
thereof a stop rib or projection B which should extend the full width or thickness
of the eye or opening C in the head of the shank D through which eye or opening
the said cross or fluke piece A passes and in which it can move In connection
with the said eye or opening C in the head of the shank D I make a recess
or slot E extending from side to side thereof to receive the said stop rib or
projection B on the anchor cross. The said recess or slot E is of sufficient length
to allow of the necessary movement of the crown arms or fluke piece A and
I secure the crown arms in position in any suitable way for example by bolting or
otherwise securing plates F over each side of the head of the shank to cover the
end openings of the said recess at each side. The plates are shewn in the drawing.
as being secured by a bolt G and Cotter H. I may or may not cut away the
inward part at each end of the rib or projection B on the anchor cross as shewn in
dotted lines at b in figure 3 the object of the cutting away when it is adopted
being that the side strain may be brought on the said plates F as near to the
securing bolts or fastenings as possible. This cutting away is therefore more
useful where small securing bolts are used than it is when one bolt is used as
shewn in the drawing. I may construct the remaining parts of the anchors or
parts connected therewith in any suitable way usual in anchors of this class. The
recess E in the head of the shank constitutes such an enlargement of the eye or
opening that larger flukes can be made than hitherto as they can be passed
through the extended space afforded by the said eye or opening and recess
combined. The drawing illustrates the front arms I as being made of a shape and
temper to stand the ordinary Admiralty test and to form part of the permanent

page_text: holding power of the anchor but I do not limit myself to the use of arms of this
shape or indeed to using any front arms or stock at all as the anchor can be made
"stockless" if required.
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:
First-In anchors of the class referred to a recess or slot in connection with the
eye or opening in the shank head the said recess or slot extending the full width
or thickness or from side to side of the shank head and receiving a stop rib or
projection on or about the centre of length of the anchor cross or crown arms and
on the inner side of the periphery thereof substantially as herein before described
and illustrated.
Second-The arrangement and combination of parts constituting the anchor
hereinbefore described and illustrated in the accompanying drawing.
JOSEPH WRIGHT.
