PROVIDIUNAL SPECIFICATION.
Improvements in 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 steam generators and the chief object
of my improvements is to arrest, absorb and utilize for steam generating purposes
a large proportion of the heat from the gases passing from the furnace through the
boiler flues and along the boiler sides.
I accomplish this object by building in the flues an inner wall of metallic bricks
or plates in such manner as to form an additional heat absorbing area. The bricks
or plates may be of iron or any other suitable metal and of any suitable regular or
irregular form. For example, the bricks or plates may be of segmental form so
that when placed in position within a circular or other flue they would be self
securing although any other convenient method and means of fixing them in their
places may be adopted.
Dated this 12th day of October 1893.

COMI LEID DI DUIFICATION.
Improvements in 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 steam generators and the chief object
of my improvements is to arrest, absorb and utilize for steam generating purposes
a large proportion of the heat from the gases passing from the furnace through the
boiler flues and along the boiler sides.
I accomplish this object by building in the flues an inner wall of metallic bricks
or plates in such manner as to form an additional heat absorbing area. The bricks
or plates may be of iron or any other suitable metal and of any suitable regular or
irregular form. For example, the bricks or plates may be of segmental form so
that when placed in position within a circular or other flue they would be self
securing.
And in order that my invention may be fully understood and readily carried into
effect I will describe the accompanying sheet of drawings reference being had to
the figures and letters marked thereon.
Figure 1 is a front sectional elevation of a Lancashire or two flued boiler fitted
with my improvements.
Figs. 2, 3 and 4 are detail views of the preferred form and section of metallic
brick.
In these views, a designates the shell of the boiler bb the furnace flues and e the
metallic bricks, one of which is shown detached in the detail views, Figs. 2, 3 and 4.
The metallic bricks c being of the form shown do not require any bolts, rivets or
other fastenings but are self securing in position and are arranged round the sides
[Price 8d.]

page_text: of the flues as illustrated in Fig. 1. The bricks c are preferably made of iron and
in
any suitable shape so long as one of the essential features of my invention is
retained, that is to say, the form of the metallic bricks must be such that they will
keep their position in the flue without the use of any fastening.
Although I have only shown the said bricks e placed round the lower portion and
sides they may be placed in the form of an arch round the upper portion of the
flues if found advantageous or desirable; but care must be taken not to impede the
free draught or circulation of the flames and heated gases.
It will be obvious that the metallic bricks c are easily applied and as readily
removed when not required or for repairing or other purposes.
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 construction use and application of metallic bricks as a wall or lining for
boiler flues, said metallic bricks serving to arrest absorb and utilize heat for the
generation of steam and being of such form as to be self securing or supporting in
position without separate fastenings substantially as herein set forth.
2. The combination with a boiler flue, of the metallic bricks e substantially as
and for the purposes described with reference to the accompanying drawing.
