PROVISIONAL SPECIFICATION.
Improvements in Boilers for the Heating of Water or other Liquids.
We, GEORGE MILTON of The Vineries, Jersey, Fruit Grower, and WILLIAM
JOHN JONES of 19 Great George Street, Westminster, Engineer, do hereby
declare the nature of this invention to be as follows:-
This invention relates to boilers adapted for the heating of water or other
liquids, the construction being such that an increased or decreased capacity can
readily be secured with a corresponding increase or decrease in the surface
submitted to the heat action.
According to our invention we propose to form the boiler of two or more
sections and for the purpose of convenience of description we will assume that it is
desired to construct what may be called a horizontal boiler of three sections as
from such a description the nature of our invention will be clearly understood.
Each section may be made in cast metal in the form of a rectangular box
provided with an inlet opening at one end and an outlet opening at the other end
while projecting from the lower surface of the box are a series of longitudinal
webs or gills which will break up the flame and form small flues or heat passages
along the box section besides absorbing and conducting thereto a considerable
amount of heat. One of the sections so formed is supported in brick work by its
outside webs or gills over the furnace grate the second section is placed on the
first but preferably so that its rear end extends to the furnace wall and beyond
that of the lower section the front end standing corresponding back. The third
section is placed on the second the ends being in the same vertical plane as the
lower section and a baffle plate extends from the bottom of the top section to the
top of the bottom section. The inlet pipe being at the rear of the lower section
the outlet would be at the forward end of the top section while the middle section
would be connected at its forward end with the lower and at its rear end with the
top section. With this construction the flame and beat would travel between the
webs on the lower section to the rear thereof then over such section between
the webs on the second section to the front of same then owing to the baffle plate
they would travel back between the webs on the third section and over same to
the chimney.
"
It will be evident that the shape number and arrangement of the sections may
be varied to meet the requirements of different localities or uses without departing
from the nature of our invention.

COMPLETE SPECIFICATION.
Improvements in Boilers for the Heating of Water or other Liquids.
We, GEORGE MILTON of The Vineries Jersey, Fruit Grower, and WILLIAM
JOHN JONES of 19 Great George Street, Westminster, Engineer, do hereby
declare the nature of this invention and in what manner the saine is to be
performed, to be particularly described and ascertained in and by the following
statement :-
This invention relates to boilers for the heating of water or other liquids, the

page_text: construction being such that an increase or decrease of capacity can readily be
secured with a corresponding increase or decrease on the surface submitted to the
heat action..
We will illustrate our invention in connection with a boiler adapted for the
heating of greenhouses of which in the accompanying drawings
Fig. 1 is a longitudinal sectional elevation on line a-a, Fig. 3.
Fig. 2 is a plan on line b-b, Fig. 1, and
Fig. 3 is a cross section on line c-c, Fig. 1.
The boiler is built up or composed of a number of cast iron water receptacles 1,
three of which arranged horizontally are shown in the accompanying drawing,
though it will be evident that one or any number may be employed depending
upon the capacity of the boiler required, and also that they may be placed
vertically or, at an angle as desired. Each section 1 which is in the form of a box
is provided with an inlet opening 2 at one end, and an outlet opening 3 at the
other end, while projecting from the lower surface of the box and preferably cast
therewith are a series of longitudinal webs or gills 4 preferably somewhat shorter
than the box portion which will space the sections apart, break up the flame and
form small flues or heat passages above the upper surface of one section and
below the lower surface of the next, the webs or gills serving also to more rapidly
conduct the heat to the section to which they are attached. The webs or gills
may be slightly tapered downward from the outlet to the inlet ends for the purpose
of assisting the flow.
The lowest section 1 is supported by its webs on a part of the brickwork walls
of the furnace and over the furnace grate 5, the next section is placed on the first
but preferably so that its rear end extends nearly to the furnace wall and beyond
that of the lower section, the front end standing correspondingly back. The third
section is placed on the second, the ends being in the same vertical plane as the
lower section, and a baffle plate 6 of refractory material extends from the bottom
of the top section to the top of the bottom section. The outlet of each section is
connected to the inlet of the next above it by means of a pipe 7 except the inlet of
the lowest section which is connected to the return or inlet pipe 8 and the outlet of
the top section which is connected to the flow or outlet pipe 9. Suitable openings 10
are provided in the furnace walls for the purpose of enabling the flues and
sections to be cleaned.
It will be seen that the flames and heat will travel between the webs of the
lowest section to the rear thereof then over such section between the webs on the
second section to the front of same, then owing to the baffle plate they will travel
back between the webs on the third section and over the section to the chimney.
In place of forming the webs as a part of the sections the webs may be formed
apart therefrom, but in this case their heat conducting properties are not so well
utilized.
It will be seen that this arrangement of separate sections provided with webs is
of advantage as it enables boilers of different sizes to be readily built up, and it
also enables a damaged section to be replaced very readily. The particular
arrangement of the sections may be varied to meet different requirements without
departing from the nature of the invention.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. A boiler consisting of one or more water receptacles or sections provided with
webs or gills and inlets and outlets substantially as and for the purpose
described.
2. A boiler consisting of the water receptacles or sections provided with webs or
gills, and inlets or outlets arranged substantially as described and illustrated.

page_text: 3. The improvements in boilers for the heating of water or other liquids
substantially as described.
