page_text: I, SAMUEL WIDDOWS of High Bank Adlington, in the County of Lancaster,
Cotton Spinner, do hereby declare the nature of my invention to be as follows:-
The object of this invention is the construction of an apparatus for effectually
heating Churches, Schools, public and other buildings and with pure air heated to
the desired temperature which apparatus is entirely self-contained and whereby
it is impossible for sulphurous or other deleterious fumes to escape and enter the
building or apartment being heated.
It consists of a cast-iron self-feeding stove coupled to a cast-iron pipe-plate
which plate receives the extremities of a series of cast-iron or other pipes arranged
one above another in a brick chamber and which terminate in another similar cast-
iron plate at the far end of the chamber. Over the ends of these plates I arrange
a cast-iron box which is so internally sub-divided as to compel the products of
combustion to pass first through the lower series of pipes and then to pass to and
fro through all the remaining pipes until finally the flue is reached.
The front box is in connection with a fire place by preference self-feeding as
aforesaid and which is enclosed in the same brickwork, or the products of co.nbus-
tion may be received from any existing furnace. At the back of the chamber
I arrange a door or doors whereby an entrance may be effected to the interior of
the tubes to facilitate the clearing-out of the same say by the introduction of a
flue brush.
The air to be heated is permitted to enter the brick chamber at the bottom and
in passing over the outside of the tubes, so arranged and heated as aforesaid,
becomes its elf heated in turn and escapes by means of a suitable flue and thus may
be carried to any desired part of a building requiring to be heated.
This improved apparatus forms a valuable adjunct to hot-water heating appa-
ratus as the pipes herein before described may be heated by the waste products of
combustion from the furnace.

page_text: I SAMUEL WIDDOWS of High Bank, Adlington, in the County of Lancaster,
Cotton Spinner, do hereby declare the nature of my 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 this invention is the construction of an apparatus for effectually
heating Churches, Schools, public and other buildings and with pure air heated to
the desired temperature which apparatus is entirely self-contained and whereby it
is impossible for sulphurous or other deleterious fumes to enter the building or
apartment being heated.
On the accompanying drawing Fig. 1. is a front elevation and Fig. 2 is a back
elevation of my improved heating apparatus and Fig. 3. is a side elevation and
Fig. 4. a plan (both partly in section) of the same apparatus. Fig. 5 is a front
view of one of the tube plates removed.
My improved apparatus consists of a cast-iron self-feeding stove a. coupled to
a cast-iron pipe-plate b. (seen dotted in Fig. 3. and separately in Fig. 5.) which
plate b. receives the extremities of a series of cast-iron or other pipes c. arranged
one above another inside a brick chamber d. and which pipes terminate in another
similar cast-iron plate c. (seen dotted in Figs. 3. and 4.) at the other end of the
chamber.
"
In Fig. 6 I illustrate a sectional view of a portion of the plate b. shewing one of
the tubes c. socketted in position and illustrating how the necessary joint is made.
Over the ends of the upper series of tubes in these plates I arrange a cavity or
box marked f. and f¹ respectively formed by the horizontal division plates g. and g¹
so as to compel the products of combustion from the stove a. to pass first through
say the two lower series of pipes c. and then to pass to and fro through all the
remaining pipes (as indicated by the arrows) until finally the flue h. is reached.
The two lower pipes a are in communication with the flue of the stove a. which
is enclosed in the same brickwork or the products of combustion may be received
from any existing fire place or furnace and be passed through the series of pipes so
enclosed in a chamber as aforesaid. At the back of the chamber and of the box f¹
I arrange a door or doors i. whereby an entrance may be effected to the interior of
the tubes to facilitate the clearing out of the same, say by the introduction of a
flue brush, whilst the box f. at the front may be cleared through the soot door i.
at the side. The air to be heated is permitted to enter the brick chamber d. at the
bottom and in passing over the outside. of the tubes c. so-arranged and heated as
aforesaid becomes itself heated in turn and escapes by means of a suitable flue and
thus may be carried to any desired part of a building requiring to be heated.
In this manner I obtain large heating surface and absorb the waste heat other-
wise escaping to the chimney.
This improved apparatus thus forms a valuable adjunct to hot water or other
heating apparatus as the pipes hereinbefore described (which may be of any desired
length and number) may be heated by the waste products of combustion from the
furnace.

page_text: Having thus particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed, I.declare that what
I claim is :-
1st. The general construction and arrangement of hot air heating apparatus
substantially as herein before described.
2nd. The improved apparatus whereby the products of combustion from a stove
or furnace may be utilised for heating air substantially as and for the purposes
herein before described.
"
3rd. The employment of a series of pipes in a heating chamber as an adjunct to
existing hot water or other heating apparatus substantially as and for the purposes
herein before described.
