PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Mixing and Burning Inflammable
and Explosive Gases and Vapours.
We ALFRED HUGH TYLER and JOHN STUART ELLIS DE VESIAN of
5, Crown Court, Cheapside, London, Engineers do hereby declare the nature of
this invention to be as follows:-
Our invention consists of an improved apparatus for preventing an explosion or
combustion from passing along the pipes or passages of apparatus used for supplying
gas or vapour or any inflammable mixture of gas or vapour with air to furnaces
or burners or the like or to any other place. The apparatus consists of a mass
of shot or other particles of metal or other substance between which the gas or
vapour is compelled to pass. The shot or its equivalent being enclosed in a
chamber or a portion of the pipe or passage in such a way that the whole of the
gas is compelled to pass between the particles in fine streams. When used with
a mixture of gases this division into fine streams will also cause an intimate
mixture to be effected and will thus prevent stratification or other forms of imperfect
mixture occurring in the gas after passing through the mass.
Dated the Second day of July 1894.

Improvements in Apparatus for Mixing and Burning Inflammable
and Explosive Gases and Vapours.
We, ALFRED HUGH TYLER, and JOHN STUART ELLIS DE VESIAN, both
of 5, Crown Court, Cheapside, in the City of London, Engineers, 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, and
accompanying drawing, that is to say :-
Our invention consists of an improved apparatus to be applied to pipes or
passages through which an inflammable or explosive mixture of gas, or inflammable
vapour and air, is supplied to furnaces or hurners, or the like, or to other places;
the object of the apparatus being to prevent an explosion by the passage of flame
along such pipes or passages.
In the accompanying drawing, which is in illustration of our invention, Figure 1
is a side view, and Figure 2 a longitudinal section, of the apparatus.
The apparatus consists of a mass of shot or other particles of metal or other
suitable substance e between which particles the gas or vapour is compelled to pass.
The shot or its equivalent e is enclosed in a chamber a (which forms a portion of
the pipe or passage) in such a way that the whole of the gas is compelled to pass
between the particles in finely divided streams, b, being ends or covers screwed
upon the chamber d, and having inlet and outlet openings at c, c, and d being
diaphragms or partitions of perforated plate, wire gauze, or the like, by which
the shot or other particles are retained in position.

page_text: When the apparatus is used with a mixture of gases, or gases or vapour and air,
this division into fine streams will also cause an intimate mixture to be effected,
and will thus prevent stratifications or other form of imperfect mixture occurring
in the gases after passing through the mass.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
shot
The combination of the chamber a, covers b, b, inlet and outlet passages c, c,
or other particles e, and perforated plates or wire gauze d, arranged and operating
substantially as and for the purposes described, and illustrated.
