I, JOHN ROBERTSON of 2, Walbrook, City, in the County of London, Surveyor,.
do hereby declare the nature of this invention to be as follows:-
The object of this invention is to construct a furnace or stove to vaporize
chemical or other compounds and disseminate such created vapours where
required for fumigation or disinfection as well as extinguishing fires and for
smoking food.
This invention consists of a metal frame or outer shell of any suitable form with
closed top, in the said frame are fitted fire and ash pit doors, and fire bars are fixed
at a suitable distance above ash pit door; in the inside of furnace or stove at a
suitable height above fire bars is fitted a metal tray supported by flanges, brackets,.
bolts or hangers, on this tray is placed the chemical or other compounds to be
vaporized near the top of inner part of the furnace or stove is formed a suitable
hole for the fumes from the vaporized compounds and smoke to be drawn from and
forced through suitable pipes or tubes by a fan machine pump or other suitable
apparatus actuated by manual or other power to the desired compartment to be
fumigated or disinfected or fire extinguishing therein, in front of the aforesaid hole
is fitted a perforated metal plate, wire work, or other suitable appliance to prevent
any solid particles or matter escaping from the aforesaid furnace or stove. This
apparatus is also applicable for smoking food.
The aforesaid furnace or stove with its attachments for working can be fitted on
a frame and readily transported where required.

COMPLETE SPECIFICATION.
An Improved Means for or appertaining to Fumigating and Disin-
fecting Dwelling Houses, Assembly Rooms, Hospitals, Churches,
Theatres, Ships, and the like, as well as for Extinguishing Fires
therein applicable also for Smoking and Curing Fish, Hams,
and other Food.
I JOHN ROBERTSON, formerly of 2 Walbrook City, in the County of London,.
but now of 178 Barry Road East Dulwich in the County of Surrey Surveyor
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 construct an apparatus in the form of a furnace
or stove, which may be used with or without fire, to create gases or vaporize
chemical or other compounds and disseminate such created gases or to vaporize
where required for fumigation as well as for extinguishing fires and for smoking
food.
Figure 1 is a side elevation (and is partially sectional so far as is shown by
letters H J K) Figure 2 is a plan view of the apparatus which consists of a metal
frame or outer shell D of any suitable form with closed but moveable top.

page_text: On the said frame are fitted fire and ashpit doors d³ and fire bars d' are fixed at
a suitable distance above ashpit doors d'. In the inside of the apparatus resting
on the fire bars and moveable is a metal basin H and at a suitable height above
the same is fitted a moveable metal tray J supported by flanges, brackets, bolts,
uprights or hangers. In or on either or any of these fire bars basin or tray is
placed the chemicals or other compounds or materials to be vaporised. Near the
top of inner part of the apparatus and attached to the pipe C is a metal perforated
plate with flange K. To stop any solid particles or matter entering into the pipe
through this plate, the fumes from the vaporised compounds are drawn from and
forced through pipe C, which is connected to the upper part of the frame D and at
the other end connected with the suction fan B, mounted on a shaft F engaging
with the tooth wheel E' on the axle E, which axle at both ends has cranks with
handles e to be worked by manual or other power so that the fumes may be driven
to the desired compartment to be fumigated or disinfected or fire extinguished
therein.
The machine is mounted on a plain wood or iron frame A or may be mounted on
a wheeled or other carriage for easy transport from place to place; when about to
be used the machine may conveniently be placed in a suitable position outside the
door of the building, compartment, room, or combined space, that requires to be
operated upon, by introducing therein a flexible hose attached to the delivery pipe
of the fan B at C¹ which conveys from the machine and delivers at C² the vaporised
chemical or created gases necessary for fumigating or fire extinguishing purposes.
This apparatus is also applicable for smoking food by removing the movable
fixtures inside and burning wood or sawdust or other suitable material therein and
forcing the smoke into the required building or compartment where required.
Having now particularly described and ascertained the nature of my invention
and in what manner the same is to be performed I declare what I claim is :-
The employment of the apparatus shown in the accompanying drawings and
marked with the letters K J and H for the purposes and substantially in manner
hereinbefore particularly described.
Dated this 15th day of April 1892.
