PROVISIONAL SPECIFICATION left by the said John Fleming Allan and
William Bennet Adamson at the Office of the Commissioners of Patents on
the 1st April 1882.
JOHN FLEMING ALLAN and WILLIAM BENNET ADAMSON, both of Glasgow, in the
County of Lanark, North Britain, " NEUTRALIZING, SEPARATING, OR ABSORBING
THE PRODUCTS OF COMBUSTION OF COAL-GAS, OR OTHER GASES, ALSO THE PRODUCTS
OF COMBUSTION OF PETROLEUM, SHALE, OR OTHER OILS,"
:
This Invention which relates to the neutralization, separation, or absorption, of
the products of combustion of coal-gas, or that of other gases, as well as the
products resulting from the combustion of petroleum, shale, or other oils, consists
in leading the said products of combustion whilst hot over surfaces of Zinc or
Iron, or Zinc and Iron, or over surfaces composed of the phosphates or phosphides
of these metals, the said products being also passed over or through a layer or
layers of carbon or its equivalent.
In carrying the Invention into practice the products of combustion from a gas-
stove, or furnace, or burner, or an oil stove, or furnace, or burner, are led through a
chamber containing plates, or strips, of zine or iron, or plates, or strips of zinc and
iron, or the phosphates or phosphides of these metals, and with or without carbon.―
The result is that certain parts of the products of combustion are thrown down,
whilst other parts are absorbed or neutralized that is to say, that their poisonous
portion or portions, giving off bad odours are rendered innocuous.
It is to be understood that any other metals, or substances, which have the effect
of separating or throwing down any portion of the products of combustion, may be
used as the equivalent of those herein before mentioned.

JOHN FLEMING ALLAN, and WILLIAM BENNET ADAMSON, both of Glasgow, in the
County of Lanark, North Britain, NEUTRALIZING, SEPARATING, OR ABSORBING
THE PRODUCTS OF COMBUSTION OF COAL GAS OR OTHER GASES, ALSO THE PRODUCTS
OF COMBUSTION OF PETROLEUM SHALE, OR OTHER OILS,"
Our said Invention which relates to the neutralization, separation, or absorption
of the products of combustion of coal gas, or that of other gases as well as the
products resulting from the combustion of petroleum, shale, or other oils, consists
in leading the said products of combustion whilst hot over surfaces of Zinc or Iron,
or Zinc and Iron, or over surfaces composed of the phosphates or phosphides of these
metals, the said products being also passed over or through a layer or layers of
carbon or its equivalent.
!
In carrying the Invention into practice the products of combustion from a gas
stove, or furnace, or burner, or an oil stove, or furnace or burner are led through a
chamber containing plates, or strips, of zinc or iron, or plates or strips of zinc, and
iron, or the phosphates or phosphides of these metals, and with or without carbon.
The result is that certain parts of the products of combustion are thrown down,
whilst other parts are absorbed or neutralized that is to say that their poisonous
portion or portions, giving off bad odours are rendered innocuous.
It is to be understood that any other metals, or substances, which have the effect
of separating or throwing down any portion of the products of combustion, may be
used as the equivalent of those herein before mentioned.
And in order that our said Invention may be properly understood we now
proceed more particularly to set forth the system, mode or manner, in or under
which the same is, or may be, used or practically carried into effect, reference being
had to the accompanying drawings, and to the letters and Figures marked thereon,
that is to say:-
Figure 1, represents in front elevation a cooking-stove constructed according to
our present Invention.
Figure 2, represents a vertical section of the same.
Figures 3, and 4, represent horizontal sections of the same.
Figure 5, represents in front elevation a heating-stove constructed according to
our présent Invention.
Figure 6, represents a vertical section of the same.
Figures 7, and 8, are respectively elevation and section of another form of
heating-stove, constructed according to our present Invention.
Figures 9, 10, and 11, are views of an apparatus constructed according to our
present Invention for neutralizing, separating, or absorbing, the products of
combustion, of coal-gas, or other gases, or petroleum, shale, or other oils, while
being used for illuminating purposes.
With reference to Figures 1, 2, 3, and 4, the products of combustion resulting
from the gases, or oils, being burned at a, for the heating of the oven A, pass from
the underside of same up in the direction of the arrows through the flues b, b, at
its sides to the plate c through which they pass at the opening d-From this
opening d, they then impinge upon and pass over the surfaces of the plates B, of
zine or iron, or zinc and iron, or plates composed of the phosphates or phosphides
of these metals and pass out from the chamber C, through the flue D, whose upper
end is charged with a quantity of carbon or its equivalent, which is supported by

page_text: the perforated plate as represented by the dotted lines e.-The products of
combustion resulting from the gases or oils being burned at f, for the heating of
the chamber C, and hot plate g, impinge upon and pass over the surfaces of the
plates B, to the flue D, in the manner hereinbefore described with reference to
those resulting from the gases or oils being burned at a, for the heating of the
oven A.
We may heat the oven A, direct from the burner a, by opening the
bottom and top of the oven A, which are formed as shewn at Figure 4, and are
similar in construction to what are known as "hit-and-miss," ventilators. The
products of combustion when in such a position partly pass up through the flues b, b,
herein before more particularly mentioned, and partly up through the openings h',
at bottom and top of oven A, where at the latter they impinge upon and pass over
the surface of the plates B, to the flue D, as herein before described.
With reference to Figures 5, and G, the products of combustion resulting from
the gases or oils being burned at h, for the heating of the stove pass from that
part up through the plate j, where they are checked by the lower plate of the
chamber i, of iron or zinc, or iron and zinc, or of the phosphates or phosphides of
these metals, and pass up the flues k, k, into the chamber Z. In this chamber 7, the
plates m, are fitted and the products of combustion impinge upon and pass over
the under and upper surfaces of these plates m, up into the flue n, and through
the perforated plate o, and through the carbon p, or its equivalent laid thereon.
With reference to Figures 7, and 8, the products of combustion resulting from
the gases being burned at q, for the heating of the boiler r, after leaving the
asbestos lumps 8, surrounding the burner q, pass up (in the direction of the arrows)
around and through and impinge upon the plates t, and u, which are respectively
similar in form and material to those represented in plan on a smaller scale at
Figures 10, and 11,--Having passed this series of plates, and around the boiler 7,
the products of combustion then pass through the perforated plate v, and through
the carbon w, or its equivalent, which is supported upon the plate v, and contained
within the box w¹. For convenience in filling the boiler r, there is provided the
funnel-topped pipe x, communicating with the same and for drawing off its
contents, there is provided the tap or bib-cock y. The burner q, is preferably
constructed on the Bunsen" principle. This stove may be mounted on the
stand z, or on any other suitable foundation, or it may be constructed if necessary
without the boiler 2, or may be used without the asbestos lumps 8, in which case it
would be heated in a similar manner to those hereinbefore described with reference
to Figures 1 to 6.
"
With reference to Figures 9, 10, and 11, the products of combustion resulting
from the gases or oils being burned within the globe a', for illuminating purposes,
impinge upon and pass over the under and upper surfaces of the plates and c¹,
(which are represented in plan respectively at Figures 10, and 11) through the
carbon d, or its equivalent, which is supported upon the perforated plate e¹, this
apparatus may be carried by the bracket f¹, attached to a chandelier or gas
branch g¹, in any suitable position or it may be carried in any other convenient
manner.
The results of the products of combustion impinging upon and passing as
hereinbefore described over the surfaces of the plates B, j, m, t, u, b', and c¹, is that
certain parts of them are thrown down, whilst other parts are absorbed, or
neutralized, that is to say, that their poisonous portion or portions, giving off bad
odours, are rendered innocuous.
Having now described and particularly ascertained the nature of our said
Invention, and the system, mode, or manner, in or under which the same is or may
be used, or practically carried into effect, we would observe in conclusion that what
we consider to be novel, and original and therefore claim as the Invention secured
to us by the hereinbefore in part recited Letters Patent is
--
The chamber or chambers fitted with plates or strips of zinc or iron, or zinc and
iron, or of the phosphates or phosphides of these metals, or their equivalents, over
whose surfaces the products of combustion of gases or oils being burned for heating

page_text: or illuminating purposes are passed, and the receptacle containing carbon
or its equivalent through which the products of combustion are subsequently
passed, in order that the portion or portions thereof giving off bad odours are
rendered innocuous, substantially as hereinbefore described with reference to the
accompanying drawings.
In witness whereof We the said John Fleming Allan and William Bennet
Adamson have hereunto set our hands and seals this Twenty-eighth day of
September in the year of our Lord One thousand eight-hundred and
eighty-two.
JOHN FLEMING ALLAN.
