I STEPHEN MARMONT of 85 Maridales Veien Christiania, Norway, Manufacturer, 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 has reference to an improved process of and means for curing
or preserving fish flesh and fowl and further has reference to apparatus employed
therefor.
My said invention consists in forcing into and through such articles at high atmo-
spheric pressure, by suitable apparatus, the following preparation or solution, namely
Salt, Saltpetre, Sugar, and Vinegar or Acetic Acid, preferably in the following
proportions Salt thirty parts Saltpetre, thirty parts Sugar! thirty parts and Vinegar
or Acetic Acid forty parts, the whole diluted with water, according to the size or
bulk of the articles to be operated upon; these are thoroughly well mixed together to
the necessary strength required for the different kinds of fish, flesh and fowl.
DESCRIPTION OF DRAWINGS.
Fig. 2 is a plan of Fig. 1.
In carrying out my invention 1 provide a tank A preferably placed upon a suitable
stand K, so as to be elevated; the tank is also provided with stairs and circular
platform M for the use of the attendants. Within the said tank are filters B consisting
of galvanized wire arranged in the form of a sieve, or woollen or cotton cloth may be
used.
The ingredients composing the preparation or solution as aforesaid are put into the
sid tank at a suitable opening provided therefor, after which the filtering means set
forth, filters the preparation until it is quite clear, when it is passed into the pressure
boiler D. by means of the tap or cock C.

page_text: Within the said pressure boiler are a series of perforated shelves E, composed of
galvanized wire or thread or reticulated plates upon which the articies to be preserved
or cured or placed; when this has been done, the pressure boiler D is then filled with
the preparation or solution from the tank A by means of the tap or cock C as
aforesaid.
When the pressure boiler D is sufficiently full, the tap or cock is closed, and the
manhole of the said pressure boiler is opened in order to see that all is clear and
in order, when this has been determined, the lid of the manhole is closed and secured,
I then, by means of the pressure pump G force the liquor preparation or solution
through the articles at a pressure of from sixty to two hundred pounds to the square
inch.
The articles must remain in the pressure boiler from six to twenty hours, when
it will be found that the preparation or solution has been completely forced through
such.
I then take the articles out of the said pressure boiler, so as to dry them, in a cold
atmosphere, or I place such in a hydro extractor H, to be dried as required; the
hydro extractor Hand pump G being driven from overhead or other shafting K¹,
operated by any suitable motor.
Fish, flesh, and fowl preserved or cured as herein set forth retains its proper colour
and form, and will keep for a long time.
After coming out of the hydro-extractor it is ready to be packed in boxes and sent
away.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The method of curing or preserving fish, flesh, and fowl, substantially as shown
and described.
2. The preparation or solution composed of Salt, Saltpetre, Sugar, and Vinegar or
Acetic Acid, as and for the purposes herein set forth.
3. The arrangement of apparatus consisting of a tank A, with filters B, pressure
boiler D, with perforated shelves E, pressure pump G, and extractor H, as and for the
purposes herein set forth.
Dated this Twenty sixth day of February 1889.
