COMPLETE SPECIFICATION (AMENDED).
Improvements in Anchors.
I, RICHARD SYKES, of the firm of Richard Sykes and Son, of Railway Works,
Cradley Heath, in the County of Stafford, Manufacturers, do hereby declare the
nature of my said 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 improvements in anchors which are very simple
in construction and are constructed so that the chain or cable is quite free to turn
round with the shank of the anchor to which it is attached thus preventing or
lessening the torsional strain.
In order that my invention may be clearly understood and more easily carried
into practical effect I have appended hereunto a double sized sheet of drawings
upon which I have illustrated examples of the same.
Figure 1 is an elevation and part section of one of my anchors with the arms B, B
and shank A in vertical line one with the other as they would show when being
lowered or raised as the head H is so formed as to be heavier than the arms so that
the points of the arms are not likely to catch against the ships sides.
Figure 2 is a similar elevation to Figure 1 but showing a modification in the
mode of mounting the shank A.
Figure 3 is an elevation of another modification but the principle is the same.
Figure 4 is a similar elevation to the other three showing a still further mode of
mounting the shank A.
Figure 5 though strictly representing and agreeing with Figure 1 may be taken
to show any of the previous four Figures as the anchor is being brought into
action.
Figure 6 is a sectional plan of the anchor on the line 1-2.
The anchor arms and head may be of steel, iron or other metal and either cast or
wrought but in all cases the shank A finishes with a ball a' at its root which will
allow the shank A to twist or turn upon its own centre without undue friction or
strain. At Figure 1 the centre portion of the head H is shown in section with the
shank in elevation. The head H or the lower portion has a considerable amount of
metal with the projecting portions h² and the metal so concentrated and arranged in
its relation to the centre of the ball a¹ that the normal tendency of the arms B is
always for them to be in line with the shank A when the anchor is hanging from
the ship, that is when it is being lowered or raised which avoids any liability for
the flukes to foul the sides of the ship. A hole ho is cast or made in the solid
head H finishing with a curved top h³ against which the ball a¹ of A works and the
shank A is put in from the bottom of the head in the case of Figures 14 and 5.
This hole is then partially filled with a such like plug as P with preferably a
hole p¹ at its centre which is left for the purpose of access to the ball a¹. The

page_text: plug P may be secured against coming out in a variety of ways but I have shown
the pins has effecting the purpose.
It will be noticed that the neck 2 of the
shank A is a loose fit as seen at its sides Figures 1, 2, 3, and 4 but the metal
is cut away across the head at ho as seen more clearly in plan at Figure 6 so
that the head has freedom in that direction to lie as seen at Figure 5.
It will be evident that the shank A may be mounted in the head according to my
invention in a variety of ways as for instance as seen at Figure 2 where the gland or
cover h is put over the shank and fastened down with bolts K these bolts being
strong enough to equal the pull upon the cable, or wrought pieces of metal E as scen
at Figure 3 may be cast into the gland or cover h' and then forged or turned round
with the ends turned up at e¹ inside the under hole for the purpose, but it must be
understood that I do not confine myself to the modes shewn in that respect as they
may be varied with similar effect. In the case of Figure 4 the arms B are forged
and placed in a mould and the head H is cast over them the shank A being
threaded through the under hole and the plug P put in afterwards as explained in
reference to Figure 1.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
:-
CLAIMS.
First The improvements in anchors constructed with a hall and socket or
universal joint at the base of the shank and in the head of the anchor so that the
shank is free to revolve upon its axis substantially as herein set forth and shewn
upon the drawings.
Second: In anchors which form the subject of the previous claim the modification
shewn by Figure 2 in which the enlargement on the shank is put in from the top
side and a gland or cover then fastened down upon it so as to leave freedom of
action as herein set forth and shewn.
Third-In anchors which form the subject of the first claim casting the head
upon the ends of the forged arms with provision for the insertion of the shank with
its enlargement substantially as herein set forth and shewn.
Fourth In anchors forming the subject of the first claim forming the head
with a hollow at the upper side to receive the enlargement of the shank and
securing a gland or cover upon the enlargement with projecting wrought pieces of
metal which pass through holes in the head to the under side which are afterwards
turned upwards into the hole to form stops for the underside of the enlargement of
the shank as herein set forth and shewn.
