PROVISIONAL SPECIFICATION.
Improved Method of and Means for Drying and Maintaining in a
Dried Condition, Cigars, Sweets, Biscuits, and the like, the Air
of Safes, Strong Rooms, Laundry Drying Rooms, Air for
Inhalation, and for other like Purposes.
I LOUIS SINCLAIR of " "Daydawn "Netherall Gardens Hampstead London
Gentleman do hereby declare the nature of this invention to be as follows:-
My invention relates to a method of constructing boxes bags or other receptacles
containing a chemical compound capable of rapidly absorbing moisture for the
reception of cigars, sweets, biscuits and similar articles and also providing for
drying and keeping dry safes, strong rooms, laundry drying rooms and air for
inhalation for medicinal purposes. It further relates to the construction of a
brick or cake composed of asbestos and chloride of calcium capable of being used
for absorbing moisture in any receptacle or comparatively air tight chamber and
capable also of being easily and rapidly dried by fire or heat.
I find that the most suitable proportions of chloride of calcium and asbestos are
about 3 parts of chloride of calcium and 2 parts of asbestos.
For the purpose of carrying out my invention I provide a box or cabinet lined
with tin or other metal capable of excluding air having a lid or doors which close
down upon an edge of india rubber or similar resilient substance fixed to the top or
sides of the boxes upon which the lid or door is closed with the result that when
the box is closed the same is practically airtight. At the bottom of the box or
cabinet and conveniently in a flat tin or other metal receptacle perforated with
holes I place the compound or brick in question. A false bottom perforated with
holes is placed within a box or cabinet so that the articles placed therein may rest
upon it in such a manner that air will readily pass through the perforations on to
the compound or brick enclosed in the metal receptacle.
When the box or cabinet is closed and the outer air practically excluded the
compound or brick will rapidly absorb the moisture from the air inside the box or
cabinet and from the goods contained therein and the goods dried and maintained
in a dry condition.
Instead of a box or cabinet lined with metal I sometimes employ a bag made of
india rubber or other air tight substance capable of being closed or tied at the
mouth so as to exclude the air: at the bottom of each bag I place a suitable
perforated receptacle containing the compound before mentioned. I find also that
the said compound or bricks made as hereinafter mentioned can be employed for
drying and keeping dry safes, strong rooms, laundry drying rooms and air to be
used for inhalation for medical purposes.
The compound of chloride of calcium and asbestos above described is made up
into the form of a brick or cake-which when saturated with moisture is removed
and place upon a fire either in the metal receptacle or removed from it until the
moisture has been evaporated by the heat when it again becomes ready for use and
capable of absorbing damp.
These bricks could be made in any size and may not only be used for the purpose
of being used in boxes cabinets or bags but also in safes, strong rooms, drying rooms
or other comparatively air tight chambers.

I LOUIS SINCLAIR of "Daydawn" Netherall Gardens Hampstead London
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 :-
My invention relates to a method of constructing boxes bags or other
receptacles containing a chemical compound capable of rapidly absorbing moisture
for the reception of cigars sweets biscuits and similar articles and also providing
for drying and keeping dry safes strong rooms laundry drying rooms and air for
inhalation for medicinal purposes. It further relates to the construction of a brick
or cake composed of asbestos and chloride of calcium capable of being used for
absorbing moisture in any receptacle, or comparatively air tight chamber and
capable also of being easily and rapidly dried by fire or heat.
I find that the most suitable proportions of chloride of calcium and asbestos are
about three and a half parts by weight of chloride of calcium, and two
parts of asbestos. I construct the brick or cake before mentioned by mixing
into a dough with moisture chloride of calcium and asbestos fibres in the pro-
portions indicated. The dough so made up I place in a mould of suitable size
and shape and bake the whole in an oven until the brick or cake becomes hard and
solid when it is removed from the mould and is ready for use.
For the purpose of carrying out my invention in drying small goods and
keeping them in a dry condition I provide a box or cabinet lined with tin or other
metal capable of excluding air, having a lid or doors which close down upon an
edge of india rubber or similar resilient substance fixed in the usual manner to
the top or sides of the boxes upon which the lid or door is closed with the result
that when the box is closed the same is practically air tight. At the bottom of
the box or cabinet and conveniently in a flat tin or other metal receptacle of
convenient shape perforated with holes I place the compound or brick in question.
A false bottom perforated with holes may be placed within the box or cabinet so
that the articles placed therein may rest upon in such a manner that air will
readily pass through the perforations on to the compound or brick enclosed in
the metal receptacle. The false bottom is not essential to my invention and may
be dispensed with in which event the metal box or other receptacle containing
the compound before mentioned may be inserted in the box or cabinet with the
goods proposed to be dried or kept in a dry condition. When the box or
cabinet is closed and the outer air practically excluded the compound or brick
will rapidly absorb the moisture from the air inside the box or cabinet and from
the goods contained therein and the goods dried and maintained in a dry
condition.
Instead of a box or cabinet lined with metal I sometimes employ a bag made
of india rubber or other air tight substance capable of being closed or tied at the
mouth so as to exclude the air ;-at the bottom of each bag I place a suitable
perforated receptacle similar to that previously described containing the compound
before mentioned. I find also that the said compound or bricks made as herein-
before mentioned can be employed for drying and keeping dry safes strong rooms
laundry drying rooms and air to be used for inhalation for medical purposes
and for this purpose may be simply placed in the safes, strong rooms, or laundry
or in the receptacle from which air is to be inhaled and may be first placed in a

page_text: tin or other metal receptacle hereinbefore described and this receptacle or a
number of them may be used as before described. The compound of chloride
of calcium and asbestos above described is made up into the form of a brick or
cake which when saturated with moisture is removed and heat applied to it by
placing it upon a fire or otherwise either in the metal receptacle or removed from
it until the moisture has been evaporated by the heat when it again becomes
ready for use and capable of absorbing damp. These bricks could be made in
any size and may not only be used for the purpose of being placed in boxes
cabinets or bags but also in safes strong rooms drying rooms or other comparatively
air tight chambers for the purposes aforesaid.
Having now particularly described and ascertained the nature of my inven
tion and in what manner the same is to be performed I declare that what I
claim is ;-
1. The use of chloride of calcium and asbestos as hereinbefore described for the
purposes and in the manner herein set forth.
2. The construction in conjunction with chloride of calcium and asbestos of
boxes cabinets bags and other receptacles as herein before described for the
purposes of drying and maintaining in a dry condition the goods placed therein.
