Improvements in Greenhouse and like Heating and Fumigating
Apparatus.
I, ELLEN LOUISA BROWNE of 14 The Ropewalk, Nottingham in the County
of Nottingham Widow, 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 this invention is to provide means whereby greenhouses and other
places may be heated fumigated or the like and the air kept moist. For this
purpose I provide a boiler heated from a sliding firebox and generating steam or
vapour which passes out of the boiler at the top through a circulating or other pipe
having distributors connected with it through which the steam or vapour passes
into the air and while conveying the heat also provides the moisture. The firebox
at the back is open for the greater part of its height so that the flame can pass
over and reach the boiler. A pipe is fixed to the bottom of the boiler to draw off
the water and a safety-valve at the top in case of undue pressure of steam.
boiler has one or more tubes through which the flame and heat pass. The water
may be supplied from a tank or may be poured into the boiler through the safety-
valve hole, the safety-valve being made to unscrew for the purpose. The
distributors are cone-shaped with the base uppermost.
The accompanying drawings shew the apparatus.
The
Figure 1. is a longitudinal section through the flue shewing the position of the
boiler, firebox, ashpit and distributors.
Figure 2. is a section through the firebox.
Figure 3. is a sectional view on line xx of Figure 4. which is a plan of the boiler
and firebox.
The different parts are denoted by letters, as follows, boiler B, firebox C,
ashpit A, flue to chimney S, distributors D, steam or vapour pipe P, safety-valve
on boiler V, face of firebox E, ring on face of firebox R, outlet O for steam from
boiler, taps for distributors H, tap for emptying boiler T, the arrows indicate the
direction of the draught.
In applying this invention the suitably guided firebox C is drawn out by means
of the ring R, and when the fire is lit, it is pushed in again, and the necessary
draught is supplied, as indicated by the arrows on the drawing, from the ashpit A
which is open at one end and supplied with suitable dampers. The flames from
the firebox C pass into the space between it and the boiler B and into the boiler
tube F and thence into the flue S which may be used to obtain floor heat and which
communicates with the chimney. The steam or vapour generated in the boiler B
passes out at the top through the outlet into the pipe P and thence to the
distributors D which are furnished with taps H. If the distributors have a
perforated plate at their top the steam is broken up and does not enter the air in a
compact mass. Tobacco may be introduced into the boiler for the purpose of
impregnating the steam or vapour and while destroying certain insects it will not
in this form injure delicate plants as it would do if burnt in the ordinary way.
the same manner other fumigating or deodorizing substances may be introduced
into the steam or vapour.
In
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1 In heating and fumicating annaratus the combination of a fire box, a boiler

page_text: heated therefrom, a discharge flue for the products of combustion and adapted to
produce floor or wall heat, a circulating or other pipe connected with the boiler
and steam or vapour distributors connected with the pipe, all substantially as
described.
2. The improved arrangement of apparatus forming a heating and fumigating
system substantially as described, and illustrated in the accompanying drawings.
Dated this Twenty-ninth day of January 1894.
