AN IMPROVED FORM OF BOILER FOR HEATING PURPOSES
Year: 1885

page_text: I, JAMES ANDERSON of 53 Woodstock Road Belfast in the County of Down
Ireland Mechanic do hereby declare the nature of my invention for AN IMPROVED
FORM OF BOILER FOR HEATING PURPOSES to be as follows:-
:-
This invention consists of a novel form of saddle boiler such as are used for
heating purposes where water is circulated through pipes as in horticultural houses
churches and other buildings.
The object of this invention being to obtain the greatest amount of effective
heating surface with the least depth of boiler, and this is accomplished by making
what is known as a saddle shaped boiler with terminal water end and a continuous
undivided flue on the same level as the furnace.
This shallow form of boiler being particularly advantageous in cases where it is
impracticable to lower the level of the fire owing to difficulties in drainage or other
circumstances this shallow form of boiler meets this want exactly and at same
time thoroughly utilises the heat.

COMPLETE SPECIFICATION.
An Improved Form of Boiler for Heating Purposes.
JAMES ANDERSON of 53 Woodstock Road Belfast County of Down Ireland
Mechanic do hereby declare the nature of my invention for AN IMPROVED FORM
OF BOILER FOR HEATING PURPOSES, and in what manner the same is to be
perforined, to be particularly described and ascertained in and by the following
statement:
This invention consists of a novel form of saddle boiler such as are used for
heating purposes where water is circulated through pipes as in horticultural houses
churches and other buildings.

page_text: This novel form of saddle boiler will be understood from the following description
reference being had to the drawing herewith in which the same letters and figures
of reference always apply to the same or like parts.
Fig. 1 is a general view of this form of saddle boiler.
Fig. 2 and 3 are sectional plans of same with suitable setting, the section being
taken on line Z of figs. 4, 5 and 6.
Fig. 4 is a longitudinal section of boiler and setting on line X of fig. 5, and
Figs. 5 and 6 are sections of boilers and their setting on line Y of figs. 2 and 3.
The object of the invention being to obtain the greatest amount of effective
heating surface with the least depth of boiler and this is accomplished by making
what are known as saddle shaped boilers with a terminal water end (a), and a
continuous undivided flue (b) encased by water chambers (a¹) on the same level as
the furnace (c).
This form of boiler may be made with either two flues (b) encased by water
chambers (a) as shewn in figures 1, 2 and 5, or with only one flue (b) encased by
water chambers (a') as shewn in figures 3 and 6.
The commencement or first part of the flue (b) is formed by the terminal water
end (a) in conjunction with a water chamber (a2) projecting from the side of
furnace (c) next the flue (b). and which guides the heat into contact with the
opposite side of furnace (c) and on to the terminal water end (a).
To ensure perfectly equal circulation of the water in the boiler the bottoms of
the water chambers (a¹) forming the flues (b) are connected together by a tube or
tubes (a³) placed convenient to one of the inlets for water.
This shallow form of boiler, which can be made with the flues (b) to either right
or left of furnace (c), is particularly advantageous in cases where it is impracticable
to lower the level of the fire owing to difficulties in drainage or other circumstances,
this shallow form of boiler meets this want exactly and at same time thoroughly
utilises the heat.
The flues are simple and are easy of access for cleaning 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
The form of boiler described and illustrated with a continuous undivided flue
encased by water chambers on same level as furnace.
