Chemist. "IMPROVEMENTS IN THE PACKING OR PUTTING UP OF CHLORIDE OF
LIME AND OTHER SUBSTANCES."
.
This Invention, which relates to improvements in the packing or putting up of
chloride of lime and other substances which give off unpleasant odours, as well as
substances which are liable to deliquesce on exposure to the atmosphere, consists
as follows: The package is formed of thin wood, paper, or cardboard of an oblong
or other suitable form. A bottom is fixed on to one of the open ends of this
package by enclosing it thereon with a layer of paper, gummed, glued, or otherwise
cemented to the body of the package. In this state the package is filled with the
substance, such as chloride of lime, or one of the others herein before mentioned,
and when filled the upper or open end is closed over in the manner hereinbefore
described with reference to the bottom. When the gum, glue, or other cementing
material by which the ends are secured to the body of the box is dry the entire
package with its contents is dipped into a vessel containing molten wax. On being
taken out of the vessel containing the molten wax a thin layer thereof adheres to
the whole exterior of the package, and on cooling down to the temperature of the
atmosphere the wax solidifies and forms a hermetical closure of all the joints of
the package, whereby the escape of odours is prevented, and moisture from the
atmosphere or otherwise is shut out from having access to the substance or sub-
stances so packed.
In place of using wax alone, which may be animal, mineral, or vegetable wax,
as the material for closing the joints of the packages, there may be mixed with
such wax other substances, such as rosin, pitch, or gums, in order to clieapen the
same.
In place of dipping the package into molten wax, as hereinbefore set forth, the
package may be covered over with paper or cloth coated with wax on the exterior,
and with gum, glue, or other adhesive substance at the interior.

JOHN COCKBURN STEELE, of Glasgow, in the County of Lanark, North Britain,
Chemist. "IMPROVEMENTS IN THE PACKING OR PUTTING UP OF CHLORIDE OF
LIME."
This Invention, which relates to improvements in the packing or putting up of
chloride of lime, carbonate of aminonia, pearl ash, and other substances which give
off unpleasant odours, as well as substances which are volatile or liable to deliquesce
on exposure to the atmosphere, consists as follows:-The package may be formed
of thin wood, paper, or cardboard of an oblong or other suitable form. A bottom
is fixed on to one of the open ends of this package by enclosing it thereon with a
layer of paper gummed, glued, or otherwise cemented to the body of the package.
In this state the package is filled with the substance, such as chloride of lime, or
one of the others herein before mentioned, and when filled the upper or open end
may be closed over in the manner herein before described with reference to the
bottom. When the gum, glue, or other cementing material by which the ends are
secured to the body of the box is dry the entire package with its contents is
dipped into a vessel containing molten wax. On being taken out of the vessel
containing the molten wax a thin layer thereof adheres to the whole exterior of
the package, and on cooling down to the temperature of the atmosphere the wax
solidifies and forms a hermetical closure of all the joints of the package, whereby
the escape of odours is prevented, and moisture from the atmosphere or otherwise
is shut out from having access to the substance or substances so packed.
In place of using wax alone, which may be animal, mineral, or vegetable wax, as
the material for closing the joints of the packages, there may be mixed with such
wax other substances, such as rosin, pitch, or gums, in order to cheapen the same.
Any solid fatty matter or hydrocarbon may be used in place of wax, in combination
with the above.named substances..
In place of dipping the package into molten wax, as hereinbefore set forth, the
package may be covered over with paper or cloth coated with wax on the exterior,
and with gum, glue, or other adhesive substance at the interior.
As an example of what I have found to be a very convenient form or construction
of such package I have appended hereto a Sheet of Drawings which illustrates the
mode of producing the same, that is to say:-
Figure 1 represents in plan a piece of paper, cardboard, or other suitable material
for forming the body of the box; Figure 2 represents in plan a similar piece of
material for forming the lid or cover of the box; Figures 3 and 4 represent
respectively front and side views of the lid or cover when complete; Figures 5
and 6 represent respectively front and side views of the body of the box when
complete; Figures 7 and 8 represent respectively front and side views of the body.
of the box when complete with the lid or cover placed over same.
In Figures 1 and 2 the lines marked a represent the cuts through the material
necessary for the-forming of the sides and-ends when turned up into the required.
positions. The dotted lines in Figures 1 and 2, marked b, b¹, represent the lines.
at which the material is bent or folded up to assume the shape respectively of the.
body and lid or cover, as shewn in Figures 3, 4, 5, and 6 respectively. The surfaces
indicated by the letter A are prepared with a coating of mucilage which when
moistened secures the joints of the body or lid when pressed or folded into shape.:
The body of the box is then filled with the chloride of lime, or other substance
desired, and the lid or cover placed over it; then a strip of thin paper or other

of the lid or cover with the body of the box, as represented in dotted lines B in
Figures 7 and 8; the whole when dry is then dipped into a vessel containing
molten wax or other molten substances, as hereinbefore described.
Having now described and particularly ascertained the nature of my said
Invention, and the system, mode, or manner in or under which the same is or
may be used or practically carried into effect, I would observe in conclusion that
what I consider to be novel and original, and therefore claim as the Invention
secured to me by the hereinbefore in part recited Letters Patent is,―
The package for containing chloride of lime and other substances, sealed by
dipping the said package into a molten liquid which sets upon the package when
withdrawn from the said liquid, substantially as hereinbefore described.
In witness whereof, I, the said John Cockburn Steele, have hereunto set my
hand and seal, this Seventh day of March, in the year of our Lord One
thousand eight hundred and eighty two.
JOHN COCKBURN STEELE. (L.S.)
