A New Process of Destroying Growing Weeds, their Roots, Seeds,
Grubs, Wire Worms, and the like.
PETER WATT, Draper and Clothier, 59, Belle Vue Road, Leeds, Yorkshire, do
hereby declare the nature of this invention to be as follows:-
An apparatus or machine to produce flame & hot air. The blast is produced
by a fan or steam jet driving the air through a fire of wood, coal, cokes, parrafin
spirits and the like. Through a jet or jets according to size of machine, on to
the ground, consuming & destroying the weeds growing, their roots, seeds, like
wise insects & their deposits worms, and all ground reptiles and vermin. On the
fields the machine may be drawn by a horse or horses or propelled by electricity
steam and the like. The motive power for fan may be got from travelling wheels,
or other mechanical contrivance. A defector or deflectors may be used lined
with fire resisting material, to deflect the heat. I claim that by the application
of hot air or flame, or hot air without flame, to destroy growing weeds, roots of
grasses & weeds, their seeds or the like, also grubs, worms, insects, ground reptiles
& small vermin generally with machine to be good subject matter for my applica-
tion for a patent.

I, PETER WATT, of 59, Belle Vue Road, Leeds, in the County of York, Gentle-
man, 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:-
My invention relates to the destruction of weeds or the roots or seeds likewise
insects or their deposits worms and ground reptiles and vermin by an apparatus
or machine to produce hot air or flame or hot air without flame and driving it
where required. I attain these objects with the machine or apparatus illustrated
in the accompanying drawings in which
Figure 1 is a vertical section of the machine.
Figure 2 is a plan of machine with furnace shewn in section.

page_text: A is a fan worked by hand or motive power of any description but preferably
from the travelling wheel T B the outlet for cold blast to furnace C a fire grate
1) access door to grate E is the fire, F the combustion box or smoke consumer
G the outlet for hot air and flame, H is a bend pipe with telescopic or other joint K
a spreader and deflector supported by springs SS from bogie M, P, P, are side
plates hinged and loose to retain air and flame within the width of the deflector K,
L is a fire door M. is the bogie or frame carrying fan and furnace and deflector
fitted with axles and wheels with wide tread.
The whole of the furnace and regenerator are made of firebrick or fire resisting
materials enclosed in a circular iron casing N. The blast produced by fan is
driven through the fuel E which may be of wood coal coke oils spirits or other
heat agents down the regenerator F through outlet G and pipe H. The flame and
air being directed and distributed by the deflector K on to the ground immediately
beneath thus destroying the matter as may be required during the short period
the machine is passing over the surface.
I may vary the shape and arrangement of the fan furnace and deflector without
departing from the nature of my said invention.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
In a new machine for destroying growing weeds their roots seeds grubs wire
worms and the like the combination of the fan A furnace E combustion box F
and deflector K mounted on a carriage and operated substantially as and for the
purpose herein set forth and illustrated.
