Improvements in Heating Apparatus for Buildings and the like.
SAMUEL REILLY 14 Union Street Stonehouse Plymouth Devon Plumber do
hereby declare the nature of this invention to be as follows:-
This apparatus has a large amount of beating surface but contains only a small
quantity of water and is therefore heated very quickly. By means of tubes placed
within the water tubes I also displace a quantity of water and use the internal
tubes one for flue from boiler thus utilizing all waste heat, and the other as a fresh
air inlet which fresh air in passing through the hot pipe, becomes heated before
being discharged into the room.
By means of foil shaped tubes the external uppermost spaces can be filled with
water for evaporating purposes.
The boiler C in which water is heated is externally of a truncated conical
shape.
Part of the centre of bottom to be studded with hollow rivets (see drawing base
of boiler) as size of burner may demand.
From the base of boiler at equal distances apart, three or more tubes, as may be
required in various size boilers, run to the top for the purpose of conveying and
utilising waste heat from burner at the bottom of boiler (see section).
These tubes discharge waste heat into the cylindrical converting chamber E
fixed above boiler.
From this converting chamber the circular pipe E is fixed at right angles to
the side penetrating a D shaped hollow standard and extending through a similar
D shaped hollow standard which is placed at such a distance from the first
mentioned D standard as the space to be heated may demand.
This circular pipe must be connected with the chimney of room or such exit as
may be available. Around the circular pipe and extending from the flat face of
one D to the flat face of opposite D in each of which the requisite shaped holes
have previously been made, a hollow tube which may be made of either trefoil,
quatrefoil, cinqfoil, hexafoil, septafoil, octafoil or circular shape, is fixed.
From the side of boiler and as near the top as possible, the union joint F¹ is
inserted for the purpose of conveying hot water to D shaped hollow standard and
from this chamber into the hollow tube previously specified and from thence into
the D shaped hollow standard at opposite end.
At the lower part of D standards a similar arrangement of internal circular
pipe (G) and either of the foil or circular shaped tubes as previously described is
placed.
This foil or circular shaped tube serves as the return waterway to lower part of
D shaped hollow standard and from thence to boiler by means of a union joint
inserted as close to bottom of boiler as possible.
The hot water circulation is thus completed with a small quantity of water and
a large amount of heating surface. The internal circular pipe last mentioned is.
connected with a fresh air inlet which fresh air in passing through this hot pipe
becomes heated before being discharged into the room or space to be heated.
To make the last mentioned tubes of au angular shape it will be necessary
to make elbow or square hollow standards to suit whatever angles may be
equired.

page_text: On the top of D standard nearest boiler must be inserted a screw plug for the
supply of water and in D standard furthest away from boiler a small pipe to
provide for escape of steam.
In cases of sick rooms & greenhouses where moist atmosphere is required the
uppermost hollow spaces of the foil shaped tubes can be filled with water which
becomes heated by the agency of the hot water within and so moisture is
given off.
These tubes can be used in any number either side by side, or one above the
other according to space which it is required to heat.
The drawing shown is for heating spaces of 2000 cubic feet, either with gas
or oil.
The boiler is fixed above a lighting chamber which is a metal case pierced with
lighting and air holes.
This boiler can be fixed with perfect safety in a greenhouse.
Where fuel is used a cross junction will be inserted to flue above the boiler.
The horizontal portion of cross junction will be level with and connected to the
circular flue through top flow tube as described..
At the opposite end of junction last described a movable cap would. be placed
for cleaning flue pipe through horizontal top tube.
A damper will be inserted between vertical pipe and D standard for the purpose
of stopping draught through horizontal flue should space get over heated, at the
end of this flue furthest from boiler a bend with a clearing eye piece will also be
used. This flue will be connected with a chimney or taken up to such a height
as circumstances may demand. The vertical flue of cross junction will also be
provided with a similar damper.
When lighting the fire this damper will be opened and the damper of horizontal
flue will be closed until such time as the water in hollow tube surrounding the
horizontal circular flue becomes sufficiently heated to permit of the draught
working efficiently through it.
The damper of vertical flue will then be closed and horizontal damper will be
opened and the apparatus thus heated by fuel is doing its work utilizing all waste
heat by means of horizontal flue.
Should this apparatus be made in cast metals, such as iron and the like, the
flues and outer tubes will be cast in one piece thus severing alí connection
between the different arms of the foil shaped tubes until entering hollow standards
and will have flanges cast on each end for the purpose of bolting together in such
length as may be required. In this case the round ends of D standards will be
cast independent cf the flat surface of D to allow of the tubes being bolted and
also for cleaning waterways through tube should they require it.

SAMUEL REILLY, 14 Union Street East Stonebouse Plymouth Devonshire
England, Plumber 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 :-
A heating apparatus according to this invention refers to that class in which a
number of water tubes are held horizontally in a frame, and having a fire tube or
flue passing through them, the invention having special reference to (a) the shape
of the water tubes to admit of the greatest heating surface with the smallest

page_text: quantity of water and, (b) to the employment of an air tube passing through the
heated water to cause heated air to pass into room.
To enable the invention to be properly understood I will proceed to describe the
same with aid of the drawings left with the Provisional Specification.

Fig. 2. partial plan of Fig. 1.
Fig. 3. sectional elevation.
Fig. 4. end view showing section of water pipe and fire tube or flue on line A. B...
Fig. 5 sectional elevation of boiler shell.
C, the boiler internally fitted with vertically arranged tubes C¹, for the fire to-
pass through, to increase the heating surface. These tubes come together near
the top as shown at Fig. 3; C2, lower support of boiler. D standards to support
the tube frame D¹. E fire flue passing through the upper water tube F,
terminating in a bend E. In this or other convenient part a usual damper can
be arranged. G, a tube for air to pass through, this tube passes through the lower
water tube F, the boiling water in latter heats the tube G, and consequently the
air that passes in at G¹, and through the tube. The water tubes are connected to
the boiler to secure circulation by the short connections F¹.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A heating apparatus constructed substantially as herein before described and
illustrated by the accompanying drawings.
2. In a tubular heating apparatus forming the water tubes of a trefoil quatrefoil
or such like shape.
3. In a heating apparatus, the air tube G, as and for the purposes stated.
