PRUVIDIONAL SPECIFICATION.
Improvements in Smoke Consuming Apparatus for Steam
Generators.
I, EDWARD MAKIN, Junior, of 40 New Brown Street, Manchester, in the-
County of Lancaster, Manufacturer, do hereby declare the nature of this invention
to be as follows:-
My invention relates to improvements in smoke consuming apparatus for steam
generators, and the chief object of my improvements is to consume as far as
practicable the gases which are usually allowed to escape unconsumed into the
atmosphere.
In carrying my improvements into effect I form a chamber or receiver preferably
at the back end of the boiler or steam generator and I lead or induce some of the
heated gases from the furnace flues into this chamber or receiver.
I arrange an injector or injectors, fan or other suitable means by which the.
current (or currents) of gases is induced or forced into this chamber and from
which by means of pipes flues or passages the gases are guided back to the front of
the boiler and there led into the furnace or flues.
In this manner and by these means I economise fuel and practically overcome the
smoke nuisance.

Improvements in Smoke Consuming Apparatus for Steam
Generators.
I, 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 smoke consuming apparatus for steam
generators, and the chief object of my improvements is to consume as far as
practicable the gases which are usually allowed to escape unconsumed into the-
atmosphere.
In carrying my improvements into effect I form a chamber or receiver preferably
at the back end of the boiler or steam generator and I lead or induce some of the
heated gases from the furnace flues into this chamber or receiver.
I arrange an injector, or injectors, fan or other suitable means by which the.
current (or currents) of gases is induced or forced into this chamber and from
which by means of pipes flues or passages the gases are guided back to the front of
the boiler and there led into the furnace or flues.
In this manner and by these means I economise fuel and practically overcome the
smoke nuisance.
And in order that my invention may be fully understood and readily carried into.
effect I have annexed hereto a sheet of drawings illustrating the application of my
improvements to a two flued or Lancashire boiler.
The drawing is a part sectional plan, a being the boiler shell,
the flues,
cc the furnace bars and the chamber or receiver which I form at the back end of
the boiler. Some of the heated gases issuing from the flues bb are induced to enter-

page_text: the chamber or receiver d by any suitable means as for example by means of
injectors e e fed with steam through a pipe f; from the chamber or receiver d the
gases are conducted back through pipes y or it may be through flues or passages to
the front of the boiler and there led into the furnace flues.
Instead of using two pipes passages or flies 9 and taking the gases from the ends
of the chamber or receiver d as shown I might employ a single pipe, passage or flue
and take the gases from the central portion of the chamber or receiver and at the
front end of the boiler lead the gases into the furnaces by branch pipes.
My invention may be applied to a Cornish or single flued boiler and also to
boilers with more than two flues.
Having now particularly described and ascertained the nature of this said inven-
tion and in what manner the same is to be performed I declare that what I
claim is-
The combination with a boiler having a single furnace flue or two or more flues,
of a chamber or receiver, an injector, or injectors, fan, or other suitable appliance
for inducing part of the heated gases from the flues to enter said chamber, and
means such as a pipe, or pipes, or passages for conducting said gases from the
chamber back to the furnace flue or flues at the front of the boiler substantially as
herein set forth.
Dated this 3rd day of December 1892.
