Improvements in Means for Collecting and Taking Away or Con-
suming the Fumes or the like from Burning Fuel and for
Economising Fuel.
I SAMUEL MARSH of Westminster House 33 Gildredge Road Eastbourne Sussex,
Solicitors Managing Clerk, do hereby declare the nature of this invention to be as
follows:-
My invention consists of improvements in means for collecting and taking away
or consuming the fumes or the like from burning fuel and for economising fuel
and is a vessel or receptacle the sides or surfaces of which are perforated with slits
holes orifices or aspirators or the like to which may be attached or affixed in the
interior pipes or the like. This vessel the sides of which may taper off to a neck
or otherwise is attachable or attached or affixed by the neck or other part thereof
to, or forms part of a tube shaft or funnel or the like which is of any suitable size
and shape and so made constructed fixed or placed as to create when the said vessel
is in use a quick draught or current of air through the aforesaid slits or the like
and the said tube or the like.
The shape or form of the said vessel is similar or adapted to the shape or form of
the grate stove furnace or other position or place it is required to occupy and may
be made as an inverted cone or half an one with a back to it or such other con-
venient shape or form as is required to inhale and pass into the tube or the like
the fumes from the burning fuel but it must be smaller in size than the grate or
the like so as to allow the fuel to burn freely around or in front as the case may
be; and the number shape and size of the perforations depend upon the size shape
or form of the grate or the like.
The said perforated vessel is placed in the grate or the like and the tube or the
like forming part of or attachable to it is fixed to placed in or connected with the
chimney or other receptacle for the smoke or fumes of the burning fuel.
The said tube or the like if required by the size of the grate or the like is covered
with a detachable other one with slits holes orifices or aspirators at the end which
comes in contact with or is fixed to the said vessel and the line of contact or fixture
is that which would represent the position of the surface of the fire; and between
the two tubes or the like there is sufficient space for the quick progress of the air
entering through the slits or the like at the base or lower end of the tube or the
like. Both the said tubes may be telescopic or in parts so as to allow of the draught
or current of air being increased or diminished by the lengthening or shortening
of the said tubes or the like as the case may require. At the outlet end of the said
tubes or the like may be placed a ventilating screw fan or the like for the purpose

page_text: of quickening the draught. At the same end may be placed an apparatus or con-
trivance to take or collect the smoke vapour or fumes which may be emitted from
the said tubes or the like. The said perforated vessel or receptacle with the said
tubes or the like or a part of it or them may form part of or be constructed with
any grate stove furnace or the like or the back or sides of any grate or the like
may form the back or sides of the said perforated vessel or receptacle.
The said vessel and tubes or the like or parts thereof are made in iron steel
asbestos clay or other suitable metal substance or material but preferably in some
metallic or other substance or material which radiates heat.
The object and effect of the said invention is as follows: The fumes from the
burning fuel in front of or around the said vessel are drawn into it with the
external air through the slits or the like and rapidly escape by the said tubes or
the like into the chimney or other receptacle made therefor. The perforated end
or base of the outer tube takes the fumes away from the surface or top of the fire
and through it they escape in a similar manner.
The apparatus is specially desined and adapted for a Coke fire: and is a fuel
economiser because coke can be used with it in an open grate (without exhaling
objectionable and hurtful fumes or vapour) in lieu of other fuel and the said vessel
takes up the space which otherwise would be occupied by fuel and the fuel in
front of or around it throws out a more intense heat.
Dated this 15th day of December 1896.

Improvements in Means for Collecting and Taking Away or Con-
suming the Fumes or the like from Burning Fuel and for
Economising Fuel.
I, SAMUEL MARSH, of 17 & 18 Tothill Street, Westminster, S.W. and of West-
minster House, 33, Gildredge Road, Eastbourne, Solicitor's Managing Clerk, 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 a novel apparatus for improving the draught through
barning fuel in open grates and for collecting and removing the combustion pro-
ducts therefrom.
It consists essentially of a vessel of conical form, the front face of which is per-
forated with apertures for the admission of the combustion products from the fuel,
and is placed at the back of the fire. A funnel or tube of suitable length, arranged
to project up, or enter into the grate chimney is attached to the top of the conical
portion to cause a draught.
The conical portion is preferably made in two parts, the back and base of Iron,
and the perforated far thereof in Fireclay, which parts are made to be readily
disconnected if requir d.
I will now procee' to describe the same with reference to the accompanying
drawing.
A.D. indicates the conical body of the apparatus, perforated or slotted for the
admission of air and the fumes from the fuel, when in use; the shape of this part
is preferably curved in front, at the back formed so as to fit closely against the
back of the grate, and tapering somewhat upwards to the neck B.
The funnel or tube C rests on the neck and projects a sufficient distance up the

page_text: chimney of the fireplace, and the opening in the chimney above the fire or register
of the grate is preferably nearly closed so that as much draught as possible passes
through the conical body A. D. The conical body of the apparatus consists of
A the iron back and base and D the Fire Clay perforated face. The back and face
are made so as to be readily attached without bolts or other fastenings. The
apparatus is especially suitable for use with coke or anthracite fires and also with
gas fires
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed I wish it to be under-
stood that I am aware of the Specification of William Priessnitz Bonwick
No. 6263/93 and I do not claim anything described and claimed therein and I
declare that what I claim is:-
1. An adjustable draught improver and fume collector, consisting essentially of
a hollow conical vessel having perforations in the front face, and to be placed at
the back of any open grate with a funnel or tube connected thereto, projecting up
or entering into the fire place chimney, substantially as shewn in the accompany-
ing drawing, and herein before described.
2. In an apparatus as herein described the employment of a renewable front of
refractory material, so constructed as to be easily removed and replaced, sub-
stantially as herein before described.
