IMPROVEMENTS IN ANCHORS
Year: 1882

Office of the Commissioners of Patents on the 15th November 1882.
JOHN HOWARD KIDD of Wrexham in the County of Denbigh. "IMPROVEMENTS
IN ANCHORS
"
The object of my invention is to make an anchor which will be much lighter
than those in ordinary use and parts of which may be readily replaced at sea (in
event of breakage) by new parts carried for that purpose.
In performing my Invention I cast the shank of the anchor of crucible steel,
malleable iron, or other suitable metal in two pieces so as to form at one end a fork
into which the trunnions of the fluke are fitted.
The two pieces forming the shank are secured together by means of two metal
clips or collars shrunk on by heat or fastened by a pin or in any convenient
manner. The crossbar is passed through the shank and upper clip and through
the swivel hook or eye to which the cable is attached and is secured by cotter pins.
When any of the parts get broken a cotter pin is taken out of the crossbar,
which is withdrawn, the clips are then driven off the shank, the broken part is
replaced, and the several parts secured together as before described.

The object of my Invention is to make an anchor which will be much lighter
than those in ordinary use and parts of which may be readily replaced at sea (in
event of breakage) by new parts carried for that purpose.
In performing my Invention I cast the shank of the anchor of crucible steel,
malleable iron or other suitable metal in two pieces so as to form at one end a fork
into which the trunnions of the fluke are fitted-The two pieces forming the shank
are secured together by means of two metal clips or collars shrunk on by heat or
fastened by a pin or in any convenient manner.
The crossbar is passed through the shank and upper clip and through the swivel
hook or eye to which the cable is attached, and is secured by cotter pins.*
When any of the parts get broken, a cotter pin is taken out of the crossbar,
which is withdrawn, the clips are then driven off the shank, the broken part is
replaced, and the several parts secured together as before described
And in order that my Invention may be fully understood and readily carried
into effect I will proceed to describe the accompanying Sheet of Drawings reference
being had to the figures and letters marked thereon.
Fig. 1 is a front and Fig. 2 a side elevation of an anchor made according to my
Improvements. Fig. 3 is an elevation and Fig. 4 a plan of a modification of my
Invention showing an anchor with four flukes. Fig. 5 is an elevation partly in
section of a modified form of flukes and Fig. 6 is a plan of Fig. 5 with the flukes
removed.
In Figs 1 and 2-a a¹ are the two pieces forming the shank of the anchor:
these pieces a a¹ are cast of steel, malleable iron or other suitable metal and
when fastened together form at one end a fork: the trunnions b' of the fluke b
are fitted into holes formed in this fork to receive them.
The two pieces a a¹ forming the shank are secured together by metal clips o c¹
which may be shrunk on or fastened in any other manner: the crossbar d is passed
through a hole in the shank and upper clip and through the swivel hook or eye
to which the cable is attached. The crossbar d and swivel hook e are held in
position by cotter pins at d'. The flukes may be cast of steel or other metal and
the trunnions are placed in the holes in a al made to receive them before the
pieces a a¹ are secured together by the metal clips. The flukes are free to swivel
on the trunnions.
In Figs. 3 and 4-a a¹ are two pieces of cast steel or other metal forming the
shank b is a separate piece to which the flukes c are secured by the studs & which
pass through the piece b and the flukes: the flukes are free to swivel upward on
the studs & into the positions shown by dotted lines in Fig. 3. The shank a a' is
slightly taper from end to end and is largest at the base: the hole in the piece b
may be taper also. In fitting the pieces together to form an anchor the smaller or
upper end of the shank is passed through the piece b which will rest above the
lower end of the shank and can be secured by shrinking with heat or in any other
convenient manner. The pieces a a¹ are secured together by one or more clips e
and the cable may be passed direct through the hole f in the shank and the
crossbar dispensed with or the cable may be attached to a swivel hook or eye made
as previously described.

page_text: In Figs. 5 and 6.-a a¹ are the two pieces forming the shank: 6 is a separate
piece secured to the shank as described with reference to Figs. 3 and 4; c are the
flukes secured to the piece b by studs as described.
Having stated the nature of my Invention and described the manner of
performing the same
I declare that I claim
1. The improved anchor substantially as herein shown and described.
2. Constructing anchors of several pieces of cast steel or other metal substantially
in the manner and for the purposes herein described.
In witness whereof I the said John Howard Kidd have hereunto set my hand
and seal this eleventh day of May One thousand eight hundred and eighty
three
