Improvements in Explosion Engines.
I, ANTHONY GEORGE NEW, of The Voltage, Woking, in the County of Surrey,
Engineer, do hereby declare that I am in possession of an invention the nature
of which is as follows:
In explosion engines & particularly in those in which the heavier classes of
oils are employed when the exhaust pipe in the cylinder is led directly into an
exhaust box of any of the usual types I have found that there is a great tendency
to cause the exhaust even under circumstances in which it would if permitted to
issue through a straight pipe be perfectly cloudless to become both smoky &
unpleasant smelling.
The object of my invention is to prevent this occurring & while preserving any
of the ordinary types of exhaust box for deadening the sound of the explosions to
obtain at the same time a smokeless & deodorized exhaust. This I effect by allow-
ing a certain amount of air to mix with the exhaust on its way from the cylinder.
This may conveniently be done by making the exhaust gases draw air into the
exhaust pipe or into the exhaust box itself.
To do this I may allow the exhaust pipe to enter some way into a large tube the
other end of which is fixed into the exhaust box. Where the exhaust pipe enters,
a metal ring serves to connect the exhaust pipe to this tube & into this ring is led
an air tube. A second ring which is perforated is fixed inside the larger tube on
to the end of the exhaust pipe.
The air is then sucked into the larger tube through the space between the two
rings by the rush of the exhaust gases & there mixes with them causing any
unburnt inflammable gases to burn.
The air pipe may be carried to any convenient distance & may also be provided
with a lightly springed valve which opens when air is drawn in but closes between
whiles & has a quietening effect.
I, ANTHONY GEORGE NEW, of The Voltage, Woking, in the County of Surrey,
Engineer, 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:-
In explosion engines and particularly in those in which the heavier classes of
oils are employed when the exhaust pipe from the cylinder is led directly into an

page_text: exhaust box of any of the usual types I have found that there is a great tendency to
cause the exhaust even under circumstances in which it would if permitted to issue
through a straight pipe be perfectly cloudless to become both smoky and un-
pleasant smelling.
The object of my invention is to prevent this occurring and while preserving any
of the ordinary types of exhaust box for deadening the sound of the explosions to
obtain at the same time a smokeless and deodorized exhaust. This I effect by
allowing a certain amount of air to mix with the exhaust on its way from the
cylinder. This may conveniently be done by making the exhaust gases draw air
into the exhaust pipe or into the exhaust box itself.
To do this I allow the exhaust pipe to enter some way into a large tube the
other end of which is fixed into the exhaust box.
In order that the general arrangement may be the more readily understood I
refer to the figure in the accompanying sheet of drawings: In the Figure B is
the ordinary exhaust box shown as broken away. P is the ordinary exhaust pipe
which I prefer to make of copper and which I also prefer should be bent as shown.
E is the end of the said exhaust pipe where it issues from the cylinder from which
it is preferably thermally insulated by the plate of non-conducting material J.
It enters into and stops about the centre of the larger tube or pipe T to which it
is secured by means of the plate of non-conducting material, I. From the side of
the larger tube T in the neighbourhood of the place where the exhaust pipe P
terminates debouch one or more side-ways directed pipes or tubes of which only
one A is shown in the drawing. These pipes A are closed at some distance from
their junction with the tube or pipe T by an inwards opening valve V which is
held in its seat by a very slightly loaded spring S. The spring S is so slightly
loaded that any slight difference of pressure between the outside and inside of
the pipe A is sufficient to open it.
Owing to the exhaust pipe P being bent and thermally insulated as shown and
described the exhaust gases which issue from it are at a very high temperature,
and any un-burnt gases which they contain in consequence easily take fire when
receiving an extra admixture of air. This is provided through the valves V which
are opened by the partial vacuum caused by the rush of the exhaust gases from the
end of the pipe P towards the exhaust box B. The result is to practically com-
pletely deprive the exhaust gases that finally emerge from the exhaust box B,
both of smoke and smell.
Having thus described the nature of my invention and in what manner the same
is to be performed I declare that what I claim is:
:—
The method of depriving the exhaust gases of an explosion engine of smoke
and smell by introducing to them an extra admission of atmospheric air on their
way to the exhaust box their temperature being kept sufficiently high for the
extra combustion described to take place substantially as and in the manner shown
and described.
