IMPROVEMENTS IN ANCHORS
Year: 1884

page_text: I RICHARD Fox OULD of 31 Woodstock Road Poplar in the County of
Middlesex Iron Ship Builder do hereby declare the nature of my said Invention
for "IMPROVEMENTS IN ANCHORS" to be as follows:-
My Invention relates to improvements in anchors & has for its object to provide
an anchor which is simple in construction does not require an anchor stock can.
be used with or without catheads, can be readily taken to pieces and stowed away
if required & which has greater holding power than anchors as heretofore
constructed as it has a tripping head thereby imparting simplicity of action to the
flukes or arms thus causing them to enter the ground irrespective of the direction
in which the anchor falls..
In carrying my Invention into practice I form my improved anchor in three
main parts namely the shank the trunnion having the arms or flukes and a portion
which constitutes the crown or end portion of the anchor. The shank portion is
provided at its front end or in other words at the opposite end to that to which
the shackle is secured with a semi circular recess which fits partially around the
trunnion carrying the flukes. The said shank is also provided with dovetail
recesses into which extensions from the crown part of the anchor fit. This crown
portion is provided with a semicircular bearing surface adapted to fit around the
other half of the trunnion so that when the said crown portion and shank are in
place a true bearing is formed wherein such trunnion can turn. In order to secure.
the crown portion and shank together I prefer to pass through the aforesaid shank
and the extensions of the crown portions of the anchor a pin or bolt.
To insure the flukes or arms entering the ground at a proper angle I form on
the trunnion portion carrying the flukes two projecting pieces which are adapted
to come in contact with stops on the shank at each side of the crown portion of
the anchor. These stops serve to limit the motion of the flukes and ensure their
entering the ground at a proper angle irrespective of the direction in which the
anchor falls.
To enable the flukes or arms to be readily drawn out of or lifted from the
ground I provide the aforesaid crown portion of the anchor with extensions which
when the shank is raised enable me to obtain a leverage thereby facilitating the
withdrawal of such flukes.
It will be understood from the above description that my improved anchor is
equally effective whether allowed to fall in one direction or the other.
Dated this 18th day of January in the year of our Lord One thousand eight
hundred and eighty four.

I RICHARD Fox OULD, of 31 Woodstock Road Poplar in the County of
Middlesex Iron Shipbuilder do hereby declare the nature of my said Invention
for "IMPROVEMENTS IN ANCHORS and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement, reference being had to the accompanying Drawing forming a part of this
Specification -
My Invention relates to improvements in anchors and has for its object to
provide an anchor which is simple in construction, does not require an anchor
stock, can be used with or without catheads, can be readily taken to pieces and
stowed away if required and which has very great holding power it being provided
with a tripping head so as to ensure simplicity of action to the flukes or arms
causing them to properly enter the ground irrespective of the direction in which
the anchor falls.
My Invention is illustrated in the accompanying Drawing in which
Figure 1 is a side elevation of my improved anchor with the flukes or arms
shewn in a central or horizontal position and
Figure 2 is a plan of the said anchor.
Figure 3 is a side elevation of the crown-portion or tripping head of my improved
.anchor detached.
Figure 4 is a sectional end view of the shank of my improved anchor on the
line A. A. Figure 2.
Figure 5 is a transverse section of the tripping head on the line B. B. Figure 1
a portion of the trunnion being also shewn.
Like letters indicate the same parts throughout the Drawing:
In carrying my Invention into practice I form my improved anchor in three
main parts namely the shank a the trunnion b having the arms or flukes b¹ and
the portion c which constitutes. the tripping head or in other words the crown or
end portion of the anchor. The shank portion a is provided at its front end with
a semi circular recess as at a' which fits partially around the trunnion 6 of the
flukes b. The said shank a is also provided with dovetail recesses d as shewn
more particularly in Figure 4. Into these recesses the extensions c¹ from the
tripping head or crown portion c of the anchor fit. This tripping head or crown
portion is provided with a semicircular bearing surface as at c² adapted to fit around
the other half of the trunnion b so that when the said tripping head or crown-
portion c and shank a are in place a true bearing is formed wherein such trunnion
can turn. In order to secure the tripping head or crown portion c and shank a
together I prefer to pass through the latter and the extensions c¹ of the crown
portion of the anchor a pin or bolt e which may be held in position when inserted
by a small transverse pin e'.
To ensure the flukes or arins 6' entering the ground at a proper angle I form on
the trunnion portion carrying the flukes 6' two projecting pieces 62 which are
adapted to come in contact with stops at ƒ on each side of the shank a of the
anchor. These stops serve to limit the motion of the flukes aud ensure their
entering the ground at the proper angle irrespective of the direction in which the
anchor falls. The extent of movement of the flukes b¹ in either direction is
illustrated in dotted lines in Figure 1 of the Drawing.
To enable the flukes or arms 61 to be readily drawn out of or lifted from the
ground I provide the tripping head or crown portion c of the anchor with the
extensions c* which when the shackle end g of the shank is raised enable me to
obtain a leverage thereby facilitating the withdrawal of such flukes.

page_text: It will be understood from the above description that my improved anchor is
equally effective whether allowed to fall in one direction or the other.
In some cases I attach to the tripping head c a small shackle às at h to facilitate
the fishing of the anchor.
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
The improvements in anchors substantially as herein setforth and shewn in the
accompanying. Drawing.
