I WILLIAM LINDSAY MILNE of Hounslow Road New Hampton in the County of
Middlesex Nurseryman do hereby declare the nature of this invention to be as
follows:-
The object of my invention is to provide an improved form of Boiler for Heating
Water or other liquids for circulation through buildings to be warmed, or for similar
purposes.
My said invention consists essentially in constructing a Boiler preferably of the
well known Saddle form, provided with internal flue tubes at the sides of and through
Crown of Boiler, all the joints by which the tubes are made into boiler being
caulked or otherwise secured from external surface of Boiler at front and back, thus
affording special facilities for repairs or renewals.
The flue tubes passing through the water in boiler thereby increase the effective
heating surface of boiler and conduce to economy of fuel. I do not confine myself to
any particular number or shape of fluo tubes, nor method of fixing same, further than,
that all joints are made and accessible from the outside end and front surfaces of
boiler.
The flues traverse the boiler horizontally and the heated gases pass preferably first
through the tubes in sides or wings of boiler, then are deflected by means of check
plates to the tubes which pass through the crown of boiler.
The flue tubes passing from end to end of boiler to the outside surfaces, can be
cleaned from soot or ashes by simply pushing a brush through same, and allowing
the accumulations to fall into a chamber constructed in brickwork at back of boiler,
from which it is removed through soot doors fixed in end or side walls.

page_text: I, WILLIAM LINDSAY MILNE of Hounslow Road, New Hampton, in the County of
Middlesex, Nurseryman 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:
The object of my invention is to provide an improved form of Boiler for heating
water or other liquids for circulation thro buildings to be warmed or for similar
purposes.
My said invention consists essentially in constructing a Boiler preferably of the well
known saddle form provided with internal flue tubes at the sides of & through crown
of Boiler, all the joints by which the tubes are made into Boiler being caulked or
otherwise secured from external surface of Boiler at front & back thus affording special
facilities for repairs or renewals.
The flue tubes passing through water in boiler thereby increase the effective heating
surface of Boiler & conduce to economy of fuel: I do not confine myself to any
particular number or shape of flue tubes nor method of fixing same further than that
all joints are made & accessible from the outside end & front surfaces of Boiler.
The flues traverse the Boiler horizontally & the heated gases pass preferably first
through the tubes at sides or wings of Boiler, then are deflected by means of check
plates to the tubes which pass through the crown of Boiler.
The flue tubes passing from end to end of Boiler to the outside surfaces can be
cleaned from soot or ashes by simply pushing a brush through same & allowing the
accumulations to fall into a chamber constructed in brickwork at the back of Boiler
from which it is removed through soot doors fixed in end or side walls.
And in order that my said invention may be clearly understood reference is hereby
made to the accompanying Drawings, in which similar letters of reference indicate
corresponding parts.
Figure 1 represents a longitudinal section of Boiler, while Figure 2 is a sketch of
the same, the letters A A representing the recessed sockets as proposed, tubes being
inserted as illustrated by Figure 2 letter B, while B in Figure I shows the said flue
tubes in position.
The recessed sockets A A are manufactured in the shell of Boiler to receive tubes B,
which are passed through Boiler from end to end, tube being inserted and in position
as shown on Figure 1, the space between outer surface of tube & inner side of socket,
substantially as shown in Drawings, is filled in and made water tight by means of an
india rubber ring or caulked with iron cement or other suitable material, such
caulking or making good being performed from ends or outer surface of Boiler.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion & in what manner the same is to be performed, I declare that what I
claim is :-
1st. In constructing a boiler preferably of a saddle or other similar form with
internal flue tubes at the sides and through the crown of said Boiler and so constructed
that said tubes can be fitted or replaced when necessary without removing or altering
the position of the Boiler.
2nd. In constructing recessed sockets in Boilers for the reception of such tubes so
that these may be caulked or otherwise secured from the external ends of Boiler.
3rd. In arranging the draught through the said tubes so that it travels backwards
& forwards as may be required.
