Melting it Previously.
1, FRANCISCO PEREZ-GUTIERREZ, of Rue Alcalà No. 2, Madrid, in the
Kingdom of Spain, Gentleman, 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 for its object to form common salt (chloride of sodium) into
ball or other shaped solid bodies, by moulding it after having been melted under a
heat of 772 centigrades, or made more or less plastic or liquid.
To melt the chloride of sodium any convenient form of oven may be used, for
instance such as hereinafter described.
And in order that my invention may be more fully understood I have caused to
be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Fig. 1. is a longitudinal section of the oven throngh line A-B Fig. 2.
Fig. 2 is a plan in section.
Fig. 3 is a front view of the stove.
Fig. 4. is a sectional plan of the upper portion of the stove showing the hot air
chamber, in which the chloride of sodium is desiccated previous to being melted in
the stove.
Fig. 5 is a cross section through line I-J of Fig. 2 showing an inclined
passage for the smoke from the stove.
Fig. 6 is a cross section through line C-D. of Fig. 2. showing the flue through
which the hot gases pass previous to entering the chimney as well as the hot air
chamber in which the common salt is preliminary desiccated.
Fig. 7. is a cross section through line E-F of Fig. 2. showing the fire and ash-
space of the furnace.
Fig. 8. is a cross section through line G-Ḥ of Fig. 2. showing the oven itself in
which the common salt (chloride of sodium) is melted.
In all the figures, 1 indicates the fire space, 2 the ash-space, 3 the oven itself,
4 the flue for the hot gases which is formed meandric for the purpose of facilitating
the absorption of the greater part of heat during its passage from the fire space
and thus heat the hot air chamber 7, 5 indicates the outlet of the flue for the hot
gases which communicates with the chimney, 6 the conduit through which the
common salt to be melted, after preliminary desiccation to a certain degree
in the hot air chamber, is introduced into the oven; 8 the small doors
through which, by means of suitable ladles, the melted salt is removed, 9 are
windows for the purpose of regulating the temperature in the hot air chamber 7 as
may be required, 10 is a doorway through which the hot air chamber 7 may be
entered.
With reference to the drawing it will thus be understood, that the chloride of
sodium may or may not be desiccated previous to being introduced into the oven,
where it is subjected to a temperature of 772 centigrades.

page_text: The melted salt is then directly removed from the oven by means of ladles and
placed into suitable moulds previoualy prepared to form the salt into ball or other
shaped solid bodies, suitable for commerce.
The principal object of moulding common salt (chloride of sodium) into ball or
other shaped solid bodies is to render it more suitable as a stimulant for cattle and
to improve its quality, but it will be obvious that these moulded bodies may also be
used for other agricultural purposes in general.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed I declare that what I
claim is
The process of forming common salt (chloride of sodium) into ball or other
shaped bodies, consisting in melting it to a plastic state and afterwards pouring it
into suitably shaped moulds as may be required for the various uses, substantially
as and for the phrase set forth
ated this 7th day of October 1891.
