improvements in Steam Generators.
Year: 1895

page_text: I, EDWARD MAKIN Junior, of 40 New Brown Street, Manchester, in the County
of Lancaster, Mauufacturer, do hereby declare the nature of this invention to be
as follows
My invention relates to improvements in steam generators and my improvements
consist chiefly in the arrangement use and application of a hollow cone or prefer-
ably a series of such cones placed one inside the other at the back of the bridge.
A jet (or jets) of steam or steam and air is admitted to the central cone and
draws through the other cones the gases generated in the furnace and by means of
these cones and the steam jet a thorough mixing and more perfect combustion of
the gases is insured.
Instead of a cone a series of cones I might employ any other suitable device for
increasing the velocity of the gases at or about the point of combination and
mixture with the steam.

improvements in Steam Generators.
1, EDWARD MAKIN Junior, of 40 New Brown Street, Manchester, in the County
of Lancaster, Manufacturer, 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:-
My invention relates to improvements in steam generators and my improvements
consist chiefly in the arrangement use and application of a hollow cone or preferably a
series of such cones placed one inside the other at the back of the bridge or in
other convenient and suitable position.
This cone or series of cones may be used alone but I may introduce steam or air
or mineral oil or other suitable liquid fuel or any combination of these through
the central cone or cones where they mix and become ignited.
The gases
generated in the furnace which have become comparatively cool by contact with
the boiler plate are rekindled whereby a more perfect combustion and a very high
temperature are insured.
In the accompanying sheet of drawings-
Figure 1 is a sectional elevation of a boiler fitted with my improvements.
Figures 2 and 3 are detail views on a larger scale of the series of cones.
In Fig. 1. A designates the shell of the boiler, B the furnace flue, C the fire
bars, D the bridge, E the series of cones and F the pipe for supplying air steam
or liquid fuel to the central cone.
In the drawing I have shown a series of five cones placed at the back of the
bridge D but I might employ a single cone or any other suitable number and place

series of cones I might employ any other suitable device to act as an aspirator to
mix and combine the gases generated in the furnace.
Although I have shown and described a pipe F for supplying air steam or
liquid fuel to the central cone I wish it to be clearly understood that the cones
or equivalent device arranged to act as an aspirator may be used alone to great
advantage.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
1. The arrangement use and application of a hollow cone or preferably a series
of hollow cones or equivalent device placed in the furnace flue of a steam
generator to act as an aspirator substantially as and for the purposes herein set
forth.
2. In combination, in the furnace flue of a steam generator, a hollow cone or
series of cones or equivalent device arranged to act as an aspirator and a pipe or
pipes for supplying air steam or liquid fuel or any combination of these to such
aspirator substantially as herein set forth.
