IMPROVEMENT IN PUTTING UP CAUSTIC ALKALIES.
Specification forming part of Lettere Patent No. 15S,094, dated December 22, 1874; application filed
December 14, 1874.To all whom it may concern:
Be it known that I, AnHIB n ALD K. LEE,
of the city and county of Galveston and State
of Texas,have invented certain Improvements
in Putting up Caustic Alkalies, of which the
following is a full, clear, and exact descrip-
tion.
The object of my present improvement is to
provide a simple, cheap, and reliable carrier
for securing, in small and convenient pack-
ages for domestic use, and in which they can
safely be transported, the hydrate alkalies of
soda and potassa, commonly known as caustic
soda and potassa, acids, salts, &e. The na-
ture of my invention consists in coating pa-
per or wood, first, with a composition consist-
ing of white lead ground in oil, pulverized
sulphur, and black oxide of manganese, and
which compound I form into a cement that
serves to stiffen the material which -I use as a
base, filling entirely the pores of the same,
giving it strength, solidity, and toughness
nearly equal to that of metal, and rendering
the material positively impervious to moisture
and other like destructive agents, and thus
secnrely guards against all danger of the deli-
quescence of the alkali packed therein.
The paper or wooden base having been thus
treated, my invention consists, next, in coat-
ing the same with a compound similar to that
embraced in my application filed in the United
States Patent Office, December 12, 1874, for
preventing the corrosion of metals, and which
consists of asphaltum, paraffine, black oxide of
manganese, and soapstone, the first three in-
gredients being reduced to a liquid without
heat, but simply by a product which I obtain
from distilling crude turpentine at the lowest
possible temperature, and in separating all the
pyroligneous-acid water therefrom during the
process of distillation, or while the turpentine
is yet in vapor.. This last composition renders
the paper or wood positively impervious to
the destructive action of the alkalies or other
materials, no matter how caustic in their na-
ture the same may be. The paper or wood
thus treated I form into a carrier, which may
be in the shape of a box or package of any
desired form and dimensions.The great advantages of my improvement
are found not only in its cheapness and sim-
plicity, but in the strength of the package,
which will resist all wear and tear in trans-
portation nearly equal to that of metal, and
having this advantage over metal, it will not
discolor the alkali packed therein, as metal
invariably does. And, again, it guards against
all danger of the deliquescence or caustic ac-
tion of the alkali fully as well as, if not better
than, metal. And, again, as there is some-
thing in the nature of the compositions used
which acts rather to repel than attract the al-
kali or acid to the surface of the material of
which the box is composed, the same is always
free to be removed, and does not require to be
melted or liquidized, as often is the ease when
the alkali or acids are packed in a metallic
casing.
The construction and operation of my in-
vention are as follows: In a suitable vessel I
mix my first composition or cement, and which
consists of white lead, oil, pulverized sulphur,
and black oxide of manganese. This I pre-
pare by first reducing the white lead and oil
to a positive consistency. After this is done I
add, and thoroughly mix and stir therein, in
equal proportions, pulverized sulphur and
black oxide of manganese, until a cement of
the desired stiffness is produced. With this
cement I coat any suitable paper, Manila pa-
per being preferred, or wood. The paper or
wood thus coated is allowed to dry. I then,
in a suitable vessel, prepare my second com-
position, and which, as I have said, is the same
as that embraced in my application filed in
the United States Patent Office, December 12,
1874, for an anti-corrosive coating for metals,
and which compound consists of asphaltum,
paraffine, black oxide of manganese, and soap-
stone, used in about the following proportions,
viz., asphaltum, sixty-five (65) parts; paraf-
fine, twenty (20) parts; black oxide of man-
ganese, five (5) parts; and soapstone, or its
equivalent, ten (10) parts, the first three in-
gredients being liquidized without heat, but
simply by being subjected to the action of the
product which I obtain from crude turpentine
distilled at the lowest possible degree of heat,
