PROVISIONAL SPECIFICATION.
An Improved Silent Condenser for Gas and like Engines.
I, EDWARD TURNER, of Dunham Terrace, Manchester Road, Dunham, in the
County of Chester, Mechanic, do hereby declare the nature of this invention
to be as follows:-
This invention relates to apparatus for condensing and silencing the exhaust
products of combustion as they issue from the cylinders of gas and like engines.
It consists of an improved form of condenser which is silent in action, and which
produces a vacuum, and simultaneously utilizes the heat and momentum of the
gases forming the exhaust to turn a blower or vane for the purpose of exhausting
the interior of the condenser.
In a simple form of apparatus the condenser is formed of a hollow.metal cylinder
which is immersed in a tank or other vessel of water. The exhaust pipe of the
engine is connected to the condenser preferably at its lower end in such manner
that the exhaust can enter it through a valve. To a point in the side of the
condenser one end of a pipe is connected, this pipe being coiled helically round
the condenser, and in the water vessel, while its other end is open to the lower
end of a smaller cylinder in which a vertical shaft is free to run in bearings. The
vertical shaft has fixed to it a spiral blade or vane, and this is disposed in the
cylinder in such manner that the spiral vane and shaft are caused to rotate by
the momentum of the escaping products of combustion, and thus serve to draw
out the air from the interior of the condenser. The spiral vane may rotate upon,
instead of with the shaft.
In some cases a number of vertical tubes open at both ends are inserted in the
water vessel, and fixed to the bottom of the same, thus allowing a free circulation
of air upwards and serving to cool the water.

An Improved Silent Condenser for Gas and like Engines.
I, EDWARD TURNER, of Dunham Terrace, Manchester Road, Dunham, in the
County of Chester, Mechanic, 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 apparatus for condensing and silencing the exhaust

page_text: products of combustion as they issue from the cylinders of gas and like engines.
It consists of an improved form of condenser which is silent in action, and which
produces a vacuum, and simultaneously utilizes the heat and momentum of the
gases forming the exhaust to turn a blower or vane for the purpose of exhausting
the interior of the condenser.
In a simple form of apparatus the condenser is formed of a hollow metal cylinder
which is immersed in a tank or other vessel of water. The exhaust pipe of the
engine is connected to the condenser preferably at its lower end in such manner
that the exhaust can enter it through a valve. To a point in the side of the
condenser one end of a pipe is connected, this pipe being coiled helically round
the condenser, and in the water vessel, while its other end is open to the lower
end of a smaller cylinder in which a vertical shaft is free to run in bearings. The
vertical shaft has fixed to it a spiral blade or vane, and this is disposed in the
cylinder in such manner that the spiral vane and shaft are caused to rotate by
the momentum of the escaping products of combustion, and thus serve to draw
out the air from the interior of the condenser. The spiral vane may rotate upon,
instead of with the shaft.
In order that my invention may be clearly understood, I have annexed drawings
in which:-
Fig. 1..is a sectional elevation of the condenser.
Fig. 2 is a plan.
A is the inner cylinder closed at either end into which the exhaust gases are
led through the pipe a, which is preferably provided with à valve for the purpose.
The cylinder A is surrounded by an outer cylinder. B, also closed at either end,
which may, in one form of the apparatus, contain water. C is a tube coiled
helically around the cylinder A. One end of the tube C is in communication with
the lower end of cylinder A, the other end being in communication with the upper
end of the cylinder. is a partition (pierced with a hole as at or about its centre)
across the cylinder A to deflect the gases around and up the tube C. When the
gases reach the upper end of the cylinder, they are led up a smaller cylinder or
pipe. D. A spiral blade or vane E attached to a spindle e, mounted in bearings el,
is disposed within the pipe D, and the upward passage of the exhausted gases caused
the vane E to revolve, and withdraw air from the interior of the condenser. The
exhausted gases are cooled by the water in the cylinder B while passing through
the tube C.
As a modification the use of water in the outer cylinder may be dispensed with,
and one or more openings f may be formed in the lower end thereof to admit cold
air, which may pass out through other openings f' in, the side of the outer cylinder.
The cold air will thus be heated by the exhaust gases in the tube C, and the
heated air may be used to warm offices, workshops or the like.
Or, in some cases a number of vertical tubes, open at both ends, are inserted
in the outer cylinder when it contains water, and fixed to the bottom of same, thus
allowing a free circulation of air upwards, and serving to cool the water.
The tube C instead of being.continuous, may be interrupted at intervals as shewn,
to lead into and out of rectangular or other shaped casings or boxes to cause various
chemical elements contained in the exhausted gases to be deposited therein. They
may also serve the purpose of allowing expansion of the gases at intervals.
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. The improved condenser for gas and like engines, consisting essentially of
two cylinders,, closed at either end, the exhausted gases being admitted into the
lower end of the inner cylinder and deflected, by a pierced partition therein, into
a tube, in the outer cylinder, helically coiled around the inner cylinder, and com-
municating with the upper end thereof, a pipe D, in which is disposed a spiral
blade or vane, set in motion by the upward passage of the exhaust gases, and

page_text: thereby withdrawing air from the interior of the condensers, substantially as
described and shewn.
2. In an improved condenser for gas and like engines, the inner cylinder A,
surrounded by an outer cylinder B, containing water, the helically coiled tube C,
the pipe D and the spiral blade or vane E attached to spindle e, revolving in
bearings e', substantially as described and shewn.
3. In an improved condenser for gas and like engines, the inner cylinder A,
surrounded by an outer cylinder B, provided with air inlet and outlet openings ff¹
the helically coiled tube C, the pipe D and the spiral blade or vane E attached
to the spindle c, revolving in bearings el, substantially as described.
4. The improved condenser for gas and like engines, substantially as described
and shewn.
