Complete Specification Left, 2nd Nov., 1893-Accepted, 2nd Dec., 1893
PROVISIONAL SPECIFICATION.
Apparatus for Deodorising the Exhaust of Gas or Oil Motor Engines.
We, GEORGE FRANCIS MELLEN, of Fall River in the United States of
America at present of No. 28, Victoria Street, Westminster in the County of
London, Gentleman, and WILLIAM PEABODY REID, also of No. 28 Victoria
Street, in the County of London, Gentleman, do hereby declare the nature of this
invention to be as follows:-
This invention relates to means of preventing the annoyance resulting from the
offensive smell of the gaseous products which are discharged from the cylinder of a
gas or oil motor engine.
.
For this purpose we pass the exhaust of such an engine through a long pipe, or a
pipe bent in zig zag or as a coil, or it may be through a group of pipes or other
conduits or passages presenting extended cooling surface, by which the vaporous
ingredients of the exhaust are condensed. The gases discharged from this
condenser are caused to bubble through a shallow depth of water containing in
solution deodorising substances, such, for instance, as sulphate of iron. The gases,
as they rise from this solution are comparatively free from odour.
Dated this 4th day of February 1893.

COMPLETE SPECIFICATION.
Apparatus for Deodorising the Exhaust of Gas or Oil Motor Engines.
We, GEORGE FRANCIS MELLEN, of Fall River, in the United States of
America at present of No. 28 Victoria Street, Westminster in the County of
London, Gentleman, and WILLIAM PEABODY REID, also of No. 28 Victoria
Street, in the County of 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 :-
This invention relates to means of preventing the annoyance resulting from the
offensive smell of the gaseous products which are discharged from the cylinder of a
gas or oil motor engine.
For this purpose, we pass the exhaust of such an engine through a long pipe,
or a pipe bent in zig zag or as a coil, or it may be through a group of pipes or
other conduits or passages presenting extended cooling surface, by which the
vaporous ingredients of the exhaust are condeused. The gases discharged from
this condenser are caused to bubble through a shallow depth of water containing in
solution deodorising substances, such, for instance, as sulphate of iron. The gases,
as they rise from this solution are comparatively free from odour.
Fig. 1 of the accompanying drawings is a longitudinal section and Fig. 2 is a
transverse section at X X (Fig. 1.) of deodorising apparatus according to our
invention applicable, for example, on the roof of a vehicle propelled by a gas or oil
motor.
The products of combustion, discharged from the engine as exhaust, enter by
the pipe A a condenser in the form of a rectangular casing exposed on all sides
to the air and divided into three compartments B, C, D, so that the products are
cooled and have their vaporous ingredients condensed as they pass in a zig zag
course, first forwards along B, then backwards along C, and finally forwards
along D as indicated by the arrows. From the compartment D the cooled products

page_text: pass down an expanding pipe E and through perforations at its mouth so as to
bubble up through a layer of water containing some deodorising substance in
solution or suspension. Practically we find lime water suitable for deodorising
the gases, which finally escape at F. G H are screw plugs for charging and
discharging the deodorising liquid. K is a porous screen to prevent the liquid from
splashing up to the outlet.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:
==
For deodorising the exhaust of gas or oil motor engines, apparatus consisting of
a condenser in form of a passage or set of passages exposing large surface through
which the exhaust gases pass, and a vessel containing deodorising liquid through
which they bubble before escaping, substantially as described.
Dated this 10th day of October 1893.
