page_text: I, WALTER FINCH, plumber, of Bridge Cottage, Great Shelford, Cambridgeshire,
do hereby declare the nature of the said 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 improved portable fumigating apparatus applicable for
general use, amongst other purposes, for fumigating greenhouses, buildings and other
closed places, and grape vines, rose bushes and plants generally, the same being also
applicable for fumigating and disinfecting sick and other rooms, boxes, tubs, clothes
or what else requires such treatment, and for the removal of rabbits and rats and
other vermin from holes, burrows, stacks, buildings, ships, barn and other floors, and
of bees and hornets from hives, and for various other analogous purposes.
The improved apparatus is illustrated on the accompanying drawings in longitudinal
sectional elevation in Fig. 1. through the line a, b, Fig. 2. and in transverse sectional
elevation in Fig. 2. through the line c, d, Fig. 1, and consists, essentially, in the
combination in such apparatus, of a closed chamber adapted with means of heating
and vaporizing the fumigating or disinfecting substance which may consist of
Brimstone, tobacco, or any other suitable substance, a receptacle for the fumigating
or disinfecting substance arranged above the means of heating or vaporizing the
same, and a revolving fan or equivalent means for impelling a current of air over the
heated or vaporized substance and leading the fumes thereof to an outlet from which
by flexible tubing or other suitable means the same may be led to where required for
use for general or local application; the whole being arranged in a case adapted with
means permitting of access being obtained to the heating medium, and to the receptacle
of the fumigating substance, and for admitting the impelling current of air.
On the accompanying drawings; 3, represents the said closed chamber containing
a lamp, 4, or other suitable means of generating heat the sides of the case, 5,
constitute two of the sides of the chamber, 3, and are formed in one side with a
door, 23, permitting of convenient access to the lamp, and in both sides with apertures
or holes, 24, for admitting air to support combustion and emitting the products
thereof. The top, 6, of the chamber is preferably made of sheet iron or of other

page_text: suitable metal, and at a part above the heating agent it is dished as at, 7, for the
reception of the fumigating or disinfecting compound, 8. 9, is a lid or cover hinged
at, 10, and which upon being opened permits of such compound or material being
placed in such dished part, 7°; and, 11, is an inspection opening closed by a centred
laterally moving cover, 12.-13, represents a revolving fan centred on a spindle, 14,
carried by brackets, 15, secured to the sides of the case, and which is revolved by the
handle, 16, pulleys, 17, and connecting cord or band, 18. The fan case, 19, is preferably
formed of sheet metal, and air is drawn thereinto (upon the revolution of the fan)
through the eyes, 20, and is impelled in the direction of the arrow, e, over the burning
fumigating substance, and mingles with the vapour or fumes thereof and carries the
same in the direction of the arrow, f, to the outlet, 21, from which it may be led or
distributed as required by flexible tubing, 22, the outer end of which may be adapted
with a distributing rose. A perforated guard plate may be placed at, 24, to prevent
the fumigating substance from being blown away by the impelling current of air.
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
The herein before described improved construction of fumigating apparatus.
