We ILLIUS AUGUSTUS TIMMIS of No. 2 Great George Street Westminster
S.W. Civil Engineer and WILLIAM HENRY WALENN of No. 9 Carleton Road
Fufnell Park N. Chemist do hereby declare the nature of this invention to be as
follows:-
The objects of our invention are to prevent the undue heating of any fire arms
such as rifles-machine and quick firing guns and cannons (hereinafter called fire
arms) it is well known that in cannons &c. the barrel or barrels become heated and
in repeated and rapid firing often very seriously.
With these objects in view we place round any part or parts where heat may be
generated a chamber or chambers (hereinafter called a chamber) of any convenient
size aud shape and in it we put a substance which we hereinafter call a cooling
agent and which has the power to absorb heat i.e. to keep the parts contiguous to
it cool or practically so.
This chamber may be fixed so that the cooling agent comes in direct contact
with the parts to be kept cool or it may be in itself a complete and enclosed
chamber and fitted close or attached to the parts to be kept cool.
This chamber is made of any suitable metal or other material and may be made
of material which will not be injured by contact with the cooling agent.
But we prefer to coat or line any surface that requires it which will come in
contact with the cooling agent with some material (such as copper or other suitable
substance) which shall prevent injury from such contact.
The chamber is closed and is made strong enough to prevent loss by evaporation
or vaporization even under pressure. If necessary I provide means to relieve
that pressure.
The cooling agent we employ is a crystalline body or a material which is solid
at ordinary temperatures and becomes liquid after a certain warmth or heat is
reached i.e. the water of crystallization of the body dissolves the body at a given
heat and in doing so absorbs any heat in its vicinity. This is the case with
sodium carbonate and similar substances such as acetate of soda and sulphate of
soda but we claim the use of all substances which have the above properties.
But we may not only use such substances, as under heat, are converted from a
solid to a liquid form but also those which are under heat converted from a liquid
to a gaseous form (we except water which has been used before) amongst others
we may mention bisulphide of carbon and ether (which would not be available in
a hot temperature or climate).
We may find it advisable sometimes to put some liquid with the salts or crystals
to reduce them more quickly to a liquid form such for instance as nitric acid and
ammonia. We claim the use of any two or more of the above substances in
combination.
The above described cooling agent may be used alone or in combination with
other materials such as copper or any material which does not readily retain heat
and which is a good conductor and this material we sometimes find it advisable to
nake into a cellular body i.e. with holes or cavities in which the cooling agent is
laced or we make out of this material discs or bars or coils or any other form
ttached or contiguous to the parts to be cooled and surrounded wholly or other-
vise by the cooling agent.

The chamber may be of any convenient size and shape.
The parts coming in contact with the cooling agent should either be made of or
coated with a non-oxidisable material such as copper or other available metals or
materials.
It will be readily understood how the invention can be fitted to magazine and
quick firing guns without the aid of any other drawings.

An arrangement for the cooling of fire arm barrels; which consists in a hollow
case, surrounding, the barrel or barrels containing crystalline or liquid chemicals
which are converted at certain temperatures from solid to liquid or liquid to
gaseous conditions thereby absorbing the heat that comes in contact or proximity
to them such substances being for instance sodium carbonate acetate or sulphate
and any others that dissolve in their own water of crystallisation or bisulphide of
carbon or ether substantially as and for the purposes herein before described.
