Improvements in the Manufacture of Anchors.
ባ
We, HENRY ALONZO HOUSE (Senior), HENRY ALONZO HOUSE (Junior)
both of The Orleans Boat House, Teddington in the County of Middlesex,
Mechanical Engineers, and ROBERT BINTOUL SYMON, O Abchurch Lane in
the City of London, Gentleman, do hereby declare the nature, the said invention
and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
F
In that kind of anchor, such as the "Martin" for example, in which the arm
carrying the flukes passes through and turns loosely in a hole in the shank it has
been customary to make the parts, or some of them, of forged iron or steel and to
form the part of the shank through which the arm of the flukes passes by expensive
processes and arrangements.
The object of the present invention is to produce an anchor of the above
mentioned kind in a much cheaper manner than has been practicable by the means
and arrangements heretofore in use.
For this purpose we make the anchor preferably of cast steel by first casting the
arm and flukes with the usual stops or tilting claws in one piece and we then coat
that part which is intended to pass through the eye of the shank with a paste
composed of plumbago and fire-clay or with any other suitable fire resisting
material and we then place the said part in a suitably prepared mould and cast the
shank in cast steel round the part so prepared. When the shank has cooled and
solidified and has been removed along with the arm and flukes from the mould, the
coating of fire-resisting material between the fluke arm and the eye of the shank
can be removed, and the said arm is then free to turn in the said eye to the required
extent.
Instead of casting the shank on the arm of the fluke, the process may be reversed,
that is to say the shank may first be prepared, the surface of the eye coated with
fire-resisting material, the eye end of the shank placed in a suitably prepared
mould and the flukes cast with their arm passing through the eye of the shank.
In some cases the part of the anchor, ou to or into which the other part is cast,
may be made of other material than cast steel, such as wrought iron, wrought steel
and so forth. And although we have mentioned cast steel as the metal to be
employed for the part which is to be cast on to or into the other, we do not confine
ourselves to that metal as any other metal that may be found suitable may be
employed without departing from our invention.
By these means anchors of all sizes may be produced at a much less cost than
heretofore.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is
First. The improved anchor constructed by casting the shank round the arm of
the flukes, or the arm of the flukes in the eye of the shank, substantially as
described.
Second. The process of manufacturing anchors by applying a coating of
refractory material round the arm of the flukes, or round the eye of the shank,
placing the said arm, or the said shank, in a suitably prepared mould and casting
