Improvements in or connected with Apparatus for Heating Green-
houses, and for Supplying such Structures with Heated Air,
Moisture, Fumigating Gases, and the like.
We, WILLIAM GREEN, of Garforth Nurseries, near Leeds, Nurseryman, and
BENJAMIN SEDGWICK FOSTER, of Skinner Lane, Leeds, Manufacturing Chemist,
both in the County of York, do hereby declare the nature of this invention
to be as follows:-
-
This invention refers to apparatus for heating greenhouses, and for supplying
such structures with heated air, moisture, fumigating gases, and the like; and
our object is to construct such apparatus in a simple manner and so that the
supplies of the various vapours and gases may be regulated to suit varying
requirements.
According to our invention we employ a furnace and boiler of any suitable
type, and the ordinary water circulating pipes may be connected with the boiler.
In the flue of the furnace we construct an inner tube or cylindrical chamber,
which communicates with the interior of the greenhouse through outlets con-
trolled by suitable valves. A nozzle is provided for the purpose of injecting
steam from the boiler into the tube, and the rush of steam along the tube draws
a supply of air from the entrance of the tube, and after the air has become heated
by its passage through the tube it escapes together with the steam into the
greenhouse. The air inlet to the tube is controlled by a damper and one or
other suitable number of auxiliary inlets are provided at the feed end of the tube
for the entrance of fertilizing or fumigating gases.
By the employment of the above apparatus, air of any heat, charged with any
quantity of humidity, fertilizing gas or other product, may be fed at any desired
speed to the interior of greenhouses, thus enabling various plants to be treated
in a manner most conductive to their health and growth.

page_text: both in the County of York, 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:-
This invention refers to apparatus for heating greenhouses, and for supplying
such structures with heated air, moisture, fumigating gases, and the like; and
our object is to construct such apparatus in a simple manner and so that the
supplies of the various vapours and gases may be regulated to suit varying
requirements.
In order that our invention may be clearly understood we will proceed to
describe the same with reference to the accompanying drawing, in which similar
letters refer to like parts in all the figures.
Figure 1 is a longitudinal section of an apparatus constructed according to
our invention, and Figure 2 is a front elevation of the same. Figure 3 is a
transverse section on line X, Y of Figure 1.
According to our invention we employ a furnace A and boiler B of any suit-
able type, and the boiler B is connected with a water supply pipe C which is
governed by a float or other inlet valve D. From the back of the furnace A
we project a flue E into the greenhouse, and the said flue is provided with a
chimney Fat its outer end for carrying off the products of combustion. In the
interior of the flue E we employ a tube or cylindrical chamber G, and the said
tube G is continued forward to the front of the furnace A where it is open to
the outer air. From the tube G and at suitable distances apart we project outlet
tubes H, the outer ends of which communicate with the interior of the green-
house, and these tubes H may be controlled by suitable open and shut dampers
or valves. A nozzle J is provided within the open end of the tube G for the
purpose of injecting steam from the boiler B, and the said nozzle J is connected
up to the boiler B by means of a pipe K, which latter is continued back and
communicates with the tubes H through injector nozzles L, and steam may be cut off
at each of the tubes H by means of stop valves H. The air inlet to the tube G
is controlled by a damper G¹; and an auxiliary inlet tube M is provided at the
feed end of the tube G for the entrance of fertilizing or fumigating gases, and
this tube M is also controlled by a damper M¹.
When the apparatus is at work, steam from the boiler B passes down the
pipe K and out at the injector nozzle J into the tube G, and the rush of steam
along the tube G draws in air from the outside through the open end of the
tube G. This air becomes heated in its passage through the tube G by reason
of the heat in the flue E, and it passes off in conjunction with the steam through
the tubes H into the greenhouse. When additional moisture is required, the
steam injectors L are started either separately or together as may be desired.
A water jacket N may be employed round the flue E in order to provide addi-
tional heating surface, and this water jacket may be continued to any desired
length along the flue E.
By the employment of the above apparatus, air of any heat, charged with any
quantity of humidity, fertilizing gas or other product, may be fed at any desired
speed to the interior of greenhouses, thus enabling various plants to be treated
in a manner most conducive to their health and growth.
Although we have described our invention with particular reference to green-
houses, it should be clearly understood that we do not limit its use to this
particular class of structure.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that
what we claim is:-
1. The tube G situated in the flue E and having outlet tubes II projecting
into the greenhouse, in combination with suitable steam nozzles for inducing
a draught and supplying humidity, substantially as set forth.

page_text: 2. The combination of the furnace A, boiler B, flue E, chimney F, tube G,
damper G¹, tubes H, nozzle J, pipe K, nozzles L, inlet M, damper M¹, and water
jacket N, substantially as and for the purposes set forth.
3. The general arrangement, construction and combination of the various parts
forming the apparatus for heating greenhouses, and for supplying such structures
with heated air, moisture, fumigating gases, and the like, substantially as
described and with reference to the accompanying drawing.
