Improvement in and connected with Oil and other Explosion Motors
for the purpose of Reducing the Smell and Visible Vapour of or
from the Exhaust.
I, CHARLES M. JOHNSON, of Broad Street House, Old Broad Street, in the City
of London, Engineer, do hereby declare the nature of this invention to
be as follows:-
My invention relates to oil and other motors of which the exhaust gas or fluid
has an unpleasant smell or is visible or is both apparent to the senses of sight and
smell.
My invention consists in providing the exhaust with a long tube or pipe which
is preferably, vertical or thereabouts. I may also provide the exhaust with an
exhaust box to catch any liquids or solids which may proceed from the engine
and this exhaust box is if desired provided with a filter and with diaphragms or
other devices for muffling the sound of the exhaust.
This long exhaust pipe which is carried up above the heads of the passengers
on a motor car for instance may if desired be provided with an ejector or the like
through which the air might pass when the vehicle was in motion and the air
mingling with the exhaust would serve to cool the latter and cause it to be dis-
persed more easily and to reduce the smell.
In operation I have found that there is practically no smell from the exhaust
below the level of the top of the pipe and passengers will consequently not be incon-
venienced from the smell, neither will the smell be apparent to the occupants of
other vehicles near nor to foot passengers in the neighbourhood.
In applying my invention to motor cars and vessels I may utilize the tall exhaust
pipe as a flag staff, as a mast, or as a support for an awning, sunshade, or other
object.

page_text: 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 oil and other explosion motors of which the exhaust gas
or fluid has an unpleasant smell or is visible or is both apparent to the senses of
sight and smell.
My invention consists in providing the exhaust with a long tube or pipe which is
preferably vertical or thereabouts. I may also provide the exhaust with an exhaust
box to catch any liquids or solids which may proceed from the engine and this
exhaust box if desired provided with a filter and with diaphragms or other
devices for muffling the sound of the exhaust.
This long exhaust pipe which is carried up above the heads of the passengers
on a motor car for instance may, if desired, be provided with an ejector or the like
through which the air might pass when the vehicle was in motion and the air
mingling with the exhaust would serve to cool the latter and cause it to be dis-
persed more easily and to reduce the smell.
In the accompanying sheet of drawings Fig. 1 represents in diagram form the
application of my invention to a motor carriage driven by a motor on the fore-
carriage.
A is the long tube or pipe, preferably vertical or thereabouts, which is carried
up above the heads of the passengers in the carriage B and is connected to the
exhaust pipe C of the motor.
..
At any convenient or suitable point in the exhaust pipe C between the long tube
or pipe A and the motor I may connect an exhaust or baffle box D to catch any,
liquids or solids which may proceed from the engine. This exhaust box I may
provide with any suitable diaphragms such as for example D' with or without a
filter or with a filter only or other devices for muffling the sound of the exhaust.
In the bottom of the exhaust box I may provide a door D2, slide or the like for the
purpose of removing the more dense matter. The tube or pipe A may further be
provided with an air inlet A¹ ejector or the like, through which the air might pass
when the vehicle was in motion so that the air mingling with the exhaust would
serve to cool the latter and cause it to be dispersed more easily and to reduce the
smell.
The exhaust pipe C when the motor is carried on the fore carriage I may connect
to the motor by means of flexible tubing C¹ to permit of turning the carriage.
In operation I have found that there is practically no smell from the exhaust
below the level of the top of the pipe A and passengers will consequently not be
inconvenienced from the smell, neither will the smell be apparent to the occupants
of other vehicles near nor to foot passengers in the neighbourhood.
In applying my invention to motor cars and vessels I may utilize the tall exhaust
pipe as a flagstaff, as a mast or as a support for an awning, sunshade or the like.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1. In combination with an oil or other explosion motor the application and use
of the tube A substantially as and for the purposes set forth.
2. In a motor vehicle having an oil or other explosion motor supported on the
fore-carriage the combination of the tube A exhaust pipe C and flexible tubing C¹,
substantially as and for the purposes set forth.
3. In combination with an oil or other explosion motor the application and use
of the tube A exhaust or baffle box D with or without a filter and exhaust pipe C
substantially as and for the purposes set forth.
4. In a motor vehicle having an oil or other explosion motor supported on the
fore-carriage the combination of the flexible tube C exhaust pipe C, exhaust or
baffle box D and tube A substantially as and for the purposes set forth.

of the tube A having an air inlet A', ejector or the like substantially as and for the
purposes set forth.
6. The combination of exhaust devices described and shown upon the drawing.
