We DANIEL GRANGER LEWIS at Lloyds Proving House Netherton in the County of
Stafford Superintendent and JOHN DAVIES, Bushells Buildings Henry Street West
Bromwich in the County of Stafford Anchor Smith do hereby declare the nature of
our said invention to be as follows:-
This invention has for its object improvements in anchors which are made in such a
manner as to entirely avoid the necessity of welding and the arms are so formed as
not only to act together with a parallel hold but to be brought as near together as
practicable so as to prevent undue torsion if one arm takes hold before the other.
Each of the two arms are made separately from one piece of metal and formed at
the root or broad part of the arm with a stout nose piece or shoulder against which
each trend-plate fits, and these are generally plain oblong pieces of metal each carrying
say three holes one being at the centre and one at each end stout distance bolts
passing through each end with shoulders which keep the trend. plates a parallel
distance apart. Then the shank piece which is also one solid piece of metal thick at
the root carries a large hole corresponding with the centre holes in the trend plates
and a strong pin also shouldered so as to be larger at the centre secures the shank in
its place.
When the anchor is in work the shank bears against one or other of the
end pins or distance pieces according to which way the anchor falls the trend plates
tripping the anchor into action and the arms may of course take hold on either side
and by this construction the arms need only be separated sufficiently to allow the
shank to pass between the broadened points of the arms.

page_text: We DANIEL GRAINGER LEWIS at Lloyds Proving House Netherton in the County
of Stafford Superintendant and JOHN DAVIES of Bushells Buildings Henry Street
West Bromwich in the County of Stafford Anchor Smith do hereby declare the
nature of our said invention and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement :-
This invention has for its object improvements in Anchors which are made in such
a manner as to entirely avoid the necessity of welding and the arms are so formed as
not only to act together with a parallel hold but to be brought as near together as
practicable so as to prevent undue tension if one arm takes hold and so receives the
strain before the other grips. There has been great complaints in regard to anchors
dragging because they would not take hold but this is obviated by our invention.
In order that our invention may be clearly understood and more easily carried into
practice we have appended hereunto a sheet of drawings showing six figures of the
various parts of an anchor. The one shown has the shank finishing with a shackle
but we do not confine ourselves to that as either shackle ring or swivel or other finish
may be used at the end of the shank without departure from the principle of our
invention.
Figure 1, is a front elevation of the anchor as it would appear when being lifted, or
a plan as it would lie before taking hold.
L
Figure 2, is a side elevation of the anchor in the same state as described for
Figure 1.
Figure 3, is a longitudinal section on the line A. B showing the mode in which the
parts are brought together.
Figure 4, is a cross section on the line C. D showing the construction crosswise.
Figure 5, is a side elevation of the anchor as it would drop when cast out of the
ship and before taking thorough hold.
Figure 6, is a side elevation of the anchor when it is tripped into motion by the
trend plates.
Figure 7, is a back view of the anchor showing how the two trend plates H and J
are united by the end pins P and R.
These anchors may be made of any suitable metal such for instance as steel either
cast or forged or of wrought iron or partly of one metal and partly of another. The
shank E is best constructed from one homogenious piece of metal whether cast or
forged and is provided with a clean large hole to receive the enlarged or centre part
of the pivot pin K. The trend plates H and J are next threaded one on each reduced
end of the pivot pin K and on each side of the shank E the length of the enlarged
part of the pivot pin E being such that when the trend plates H and J are brought
tightly up against the shoulders of the pin there is sufficient for the enlarged or thick
part of the shank E¹ of the shank E to work very easily without fear of it becoming
fast by corrosion. The arms M and N may well be made from cast steel or they may

page_text: be forged and they are next placed one upon each end of the pivot pin E where they
are secured and forced together by the nuts and 2. The strain upon the arms is
however borne by the shoulders formed thereon as shown at sections Figure 3 and 4
viz. and hand and as well as the shoulders m³ and ' and other similar
shoulders m and n² may be formed to abut against the other edge of each trend plate
as shown by dotted lines though we do not confine ourselves to always use any
shoulders because the shoulders ', h² and one the trend plates would sometimes
be sufficient themselves. We use this mode of piece meal construction to save expense
and to avoid as much as possible fitting but where expense is not an object we should
prefer the trend plates being solid with the arms and indeed both trend plates solid
with each other instead of uniting them with the distance pins or pieces. R. P.
When the anchor is cast out of the ship it will probably first fall somewhat as shown
by Figure 5 that is to say on the ends H' and J¹ or H2 and J2 of the trend plates
when it will be immediately tripped into action or work as shown at Figure 6 by the
action of the part H' and of the trend plates digging into the bottom and thus we
avoid the liability of the anchor dragging. When the anchor is in work the strain is
shared by the pivot pin K and either the pin R or P.
It will be clearly understood that we can make the arms M. N with either more or
less crank or even straight. The openings W and W₁ between the trend plates allow
the sand to pass through instead of impeding the action of the anchor as is the case
with some anchors which prevents them from tripping.
These anchors may be used with or without stocks.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed we declare that what we claim is :-
The improvements in Anchors having two arms in combination with trend plates by
which the anchor is tripped into action substantially as herein set forth.
