PROVISIONAL SPECIFICATION.
:
An Improved Composition or Preparation to Prevent Incrustation
in Steam Boilers.
I, WILLIAM DYMOCK PHATT of Cauldon Place, Long Row, in the Town and
County of the Town of Nottingham, Architect and Surveyor, do hereby declare the
nature of this invention to be as follows:-
I boil Irish Moss or other-gelatinous sea weed, but preferably Irish Moss, in a
sufficient quantity of water; and for such length of time, as is necessary for the whole
to become a glutinous decoction, when I add a quantity of the rootlets or germs formed
by the process of malting barley or other grain, and which are commonly called "malt
combs," and also a small quantity of dextrine. The composition or preparation is then
thoroughly mixed and poured into moulds to set, after which it is dried on a kiln, or
otherwise, and turned out in the form of blocks. The proportions of the ingredients
used will vary according to the degree of hardness of the water in which the compo-
sition is to be used.

COMPLETE SPECIFICATION.
An Improved Composition or Preparation to Prevent Incrustation
in Steam Boilers.
I, WILLIAM DYMOCK PRATT of Cauldon Place, Long Row, in the town and
County of the Town of Nottingham, Architect and Surveyor, 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:-
I boil Irish Moss or other gelatinous sea weed, but preferably Irish Moss, in the
following manner. The Moss is soaked in water for five hours, it is then drained, and
afterwards boiled without added water for one hour or such time as is required to re-
duce it to a gelatinous mass of the consistency of cream. I also mix about one pound
of dextrine or its equivalent to one gallon of water, and boil for twenty minutes,
stir ring the mass the whole time. The Irish Moss solution and dextrine in equal
weights are then mixed with "malt culms" in a wooden vessel in the proportion of
about 14 lbs. of malt culms to 5 lbs. of solution in such manner as to thoroughly
amalgamate them. A suitable quantity of the composition or preparation is then
placed in a press, so as to form it into blocks, preferably of about 10 inches by
10 inches and 3 inches thick; after pressing the composition to a solid block, it is
placed on racks in a hot chamber heated to about 200 degrees Fahrenheit, until it
is thoroughly hard and dry, the time required to dry it being about days. When
dry, the blocks are taken out and coated by dipping them into a solution of boiled
glue and treacle, which when set forms a thin hard soluble coating to protect the
blocks from damage. The blocks thus prepared are put into steam boilers, in about
the proportion of 1 lb. weight of composition to each horse power of boiler, or 1 lb.
to each 100 gallons of water. This quantity, when placed in the boiler, will keep it
perfectly free from incrustation for about 6 months without further attention.
The proportions of the ingredients used in preparing the blocks, will vary according
to the degree of hardness of the water in which the composition is to be used, a larger
proportion of Irish moss and dextrine being used when very hard water is employed
in the boiler.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, 1 declare that what I
claim is :-
or other.
The improved composition or preparation consisting of Irish moss
gelatinous sea weed, dextrine or its equivalent, and malt culms, combined, prepared,
and used in the manner herein described and for the purpose stated..
