WILLIAM E. DARLINGTON.
An Improved Fumigator.
I, WILLIAM EDWARD DARLINGTON, of 53 Glaskin Road, South Hackney,
in the County of London, Horticultural Sundriesman, 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 relates to fumigators as used for burning tobacco cloth, paper and
other materials as used in greenhouses and the like. It consists in an improved
form of fumigator, by the use of which the materials are allowed to smoulder and
produce fumes only without flames; it also serves to prevent any heat passing out
above, which might result in injury to the plant or tree under which the fumigator
was placed.
In order that my invention may be fully understood and ascertained, I append a
drawing in which my apparatus is shewn in perspective.
A designates a perforated pan or vessel in which the fire is maintained, and in
which the tobacco cloth, paper or other like material is burnt. It is perforated
with holes a for the admission of a limited quantity of air, and has feet a¹ upon
which it stands. Projecting upwardly and fixed to the edges of the pan A is a
frame D which is perforated at d for a purpose hereinafter described.
The cover or extinguisher C consists of a dish having the form of a truncated
cone; and to the bottom c of this is fixed a stem or bar B which passes through the
frame D at the point d so as to allow the bar or stem B to slide freely up and down
with the cover C. The cover is pierced at c¹ c¹ so as to allow it also to slide freely
up and down on the frame D. A pin E which is preferably attached to the
frame D by a chaine can be inserted into either of the holes b in the stem or bar B,
so as to support the bar B and cover C at any required distance above the pan or
vessel which contains the burning substance.
The object to be attained in fumigation is to secure that the materials to be
consumed shall be allowed to smoulder only without bursting into flame. This can
be done by limiting the quantity of oxygen consumed, as the intensity of the flame
and the rapidity of combustion depends upon such limitation; and this consumption
of oxygen can be easily and completely controlled by raising or lowering the

page_text: cover C. By dropping the cover C so that it rests upon the top of the pan A it
acts as an extinguisher, and puts the fire out.
The cover C acts as a diffuser causing the fumes and smoke to distribute
themselves laterally in all directions; and it also serves to prevent the heat of the
smouldering materials from affecting injuriously the plant or tree under which it
may be placed.
In some cases I dispense with the frame D, stem B, and pin E; the apparatus in
this case consisting simply of a vessel A and a cover C.
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. An improved fumigator consisting of a pan A, and a cover C, substantially as
shewn and described.
2. The improved fumigator substantially as described and shewn in the
accompanying drawings.
3. An improved fumigator consisting of a pan or vessel for containing the
burning materials, and an adjustable cover above the same by the use of
which the access of air to the vessel can be governed, substantially as shewn
and described.
4. In an improved fumigator, the combination of the pan A, the frame D, the
cover C, the stem B, and the pin E, substantially as shewn and described.
Dated this Twenty-eighth day of July 1896.
