PROVISIONAL SPECIFICATION.
Improvements in or relating to Anti-incrustation Devices for Use in
Steam and other Boilers, Kettles, and the like.
1, ELIZABETH BARNSTON PARNELL of The Nest, Clifton Road, Wallington,
in the County of Surrey, Metallurgist do hereby declare the nature of this
invention to be as follows:-
This invention relates to devices for preventing the incrustation of steam and
other boilers, kettles and the like and has for its object to provide an inexpensive
body or surface whereon the lime may deposit and which, when fully charged with
deposit, may be readily removed and a new one substituted for it.
"
The material which I have found most suitable for the purpose named is "loofah "
which exposes a very great deposit surface in proportion to its over-all dimensions.
I take portions of "loofah cut to any desired shape and insert them either
singly or any number of them struug or connected together into the vessel to be
protected against incrustation.
Instead of "loofah" I may use any other vegetable fibres, for example, New
Zealand flax answers the purpose very well; and these fibres may be tied or formed
into tufts, bundles, or the like, any number of which may be conveniently strung
together and used in the same vessel.
To prevent their floating, the devices may be weighted in any convenient
manner.

Improvements in or relating to Anti-incrustation Devices for Use in
Steam and other Boilers, Kettles, and the like.
I, ELIZABETH BARNSTON PARNELL, of The Nest, Clifton Road Wallington,
in the County of Surrey, Metallurgist, do hereby declare the nature of this
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 relates to devices for preventing the incrustation of steam and
other boilers, kettles and the like, and has for its object to provide an inexpensive
body or surface whereon the lime may deposit and which, when fully charged with
deposit, may be readily removed and a new one substituted for it.
The material which I have found most suitable for the purpose named is "loofah"
which exposes a very great deposit surface in proportion to its over-all dimensions.
I take portions of "loofah" of any desired shape and insert them either singly
or any number of them strung or connected together into the vessel to be protected
against incrustation.
In place of "loofah" or any combination therewith I may use New Zealand
flax.

The "loofah or flax or both togther may be tied or formed into tufts, bundles
or the like any number of which may be conveniently strung together and used in
the same vessel.
Convenient forms of anti-incrustation device according to this invention are
illustrated by way of example in the accompanying drawings, wherein Figures 1
and 2 are perspective views of alternative constructions of the same.
In Figure 1, A is a strip of, say, loofah for instance, wound into a close spiral as
shown, to assume a disc form in which it is retained by sewing or otherwise
fastening the adjacent coils together or by encircling the cylindrical periphery of
the disc with a band of string or metal as indicated in dotted lines.
In the modification illustrated in Figure 2 a layer B of New Zealand flax is
interposed between the consecutive "loofah " coils of the strip A (which are shown
slightly unwound) and retained in place by the sewing or merely by being gripped
between the coils of the spiral, which are tightly wound.
To prevent their floating the devices may be weighted in any convenient
manner.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that I am aware
" devices of common flax
of the suggested employment in "anti-incrustation
differing materially in character from New Zealand flax and to such employment
of common flax I make no claim but what I claim is :-
1. The employment of "loofah" for anti-incrustation purposes.
2. The employment of New Zealand flax for anti-incrustation purposes.
3. An anti-incrustation device of "loofah" and New Zealand flax.
