COMPLETE SPECIFICATION.
Improvements in and relating to Heating, Ventilating and Draught-
regulating Apparatus.
I, WILLIAM FUNNELL, of 9, Blackman Street, Brighton, and 26, Cambridge
Stables, Hove, both in the County of Sussex, Sanitary, Hot Water, and Ventilating
Engineer, 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 present invention relates to apparatus of the kind described in the Specifica-
tion of former Letters Patent granted to me, No. 18568 of 1895.
The apparatus according to my present invention may consist of two or more
independent heating chambers or boilers, each of which may be adapted for heat-
ing or if desired one may be adapted to supply hot water as a draw-off for culinary
and other domestic purposes whilst the other constitutes the heat distributor
referred to in my said prior specification.
My present invention further comprises a controller by means of which the
heated products may be directed to pass through any one or all of two or more
throats leading into a flue or chimney so as to expose a greater or less amount of
the surface of the chamber to the action of the agent and thus to regulate the
amount of heat required in the room or apartment in which the apparatus is
located. This controller is also applicable for use as a ventilator, and smoke cure
and its construction affords very efficient means of regulation.
And my invention comprises, generally, the improvements hereinafter indicated.
In the accompanying drawings,
Figure 1 is a vertical section and Figure 2 is a horizontal section on the line z z
of Figure 1 of one form of my improved apparatus.
Figures 5 and 6, and and 10 are respectively similar views of modified forms
of heating apparatus.
Figure 3 is a vertical section showing another modification.
Figure 7 is a half sectional front elevation of another form of apparatus, and
Figure 8 is a horizontal section thereof on the line z¹¹.
Figure 11 is a front elevation of a further modification and Figure 12 is a sec-
tion thereof on the line yy.
Figure 4 is a plan, and Figures 13 to 16 are details of the "controller," and
Figure 17 is a plan of a modified form thereof.
a illustrates the heating or like chamber which is made of metal welded or
rivetted and so constructed as to be capable of being fitted to any heating or fire-
place A in such a manner as to take the place of the usual back and sides of either
of them formed in brickwork or otherwise around or at the back or side of the
said fire or heating place and so as to be indistinguishable to the occupants of the
room or apartment from the usual fire back or interior of a fireplace or it may
be similarly applied to open or self-setting and other like stoves which, instead of
being set in the wall, stand independent therefrom as for example in a ship's cabin.
B is the controller, which is preferably made of cast or sheet iron or other
metal or suitable material forming throats or uptakes b, b¹. The one throat bis

page_text: provided with a damper 62 and the other throat 61 has a similar damper 6³. These
dampers may be rendered operative by rods b* and 65. The manipulation of the
dampers determines the course of the current up or through the said throats. The
various parts of the controller B may be so arranged as to interlock or interfit as
hereinafter more fully described thus enabling all screws, bolts, or other fastenings
of a like nature to be dispensed with, and rendering the entire apparatus self-
fixing and locking, thereby facilitating the erection, and likewise should occasion
arise, the dismantling or disconnection thereof. Obviously, however, other means
might be provided for holding the said parts together.
O, is a hood into which the throats 6 and 6' lead on their way to the main
chimney admission to which may be regulated by a damper c.
This hood C may
in some cases be dispensed with.
I
When it is desired to use the chamber a the damper 63 is opened causing the
hot smoke and gases or other products of the heating, or like agent to follow the
course indicated by the arrows 1 so as to expose a large amount of the surface of
the said chamber a to the action of the said agent. When the other damper b²
alone is open the more direct course indicated by the arrows 2 is taken. The
damper c serves to regulate the amount of draught.
In Figure 1 my invention is shown applied to an ordinary fire-place stove A
above which an opening d having a suitable door or cover D may be provided for
the purpose of inspection or cleansing.
In each of the modifications shown respectively in Figures 3, 5 and 6, 7 and 8,
and 9 and 10, the alternative course is indicated by the arrows 1 whilst in
Figures 11 and 12 a third course is indicated by the arrows 3.
In any of these constructions tubes either through the chambers, or across the
flues such for example as those a' shown in Figures 1 and 2, and 5 and 6, may be
used.
In Figures 7 and 8, and 11 and 12 a plurality of chambers a and a is provided.
All these modifications may be used in conjunction with the controller B or
hood C or both, suitable connections (not shown), being made in any well-known
manner.
Figures 13 to 16 illustrate my method of forming the controller B of inter-
locking and interfitting parts, which, when placed in their respective positions,
do not require any further fixing. Figure 14 shows the two sides B₁ which are tied
together by the back plate B³ (see Figure 15). Hooks h¹ on the back plate engage
the hooks h of the sides B' which sides are kept at their proper distance apart by
the lugs h. Figure 16 shows the two parts B³ and B which form the partition
between the throats b and b. The upper part B slides behind the lugs hand
rests upon the lower part B which it holds in place, and whose hooks h³ (see
Figure 1) engage hooks 6 of the sides B'. The whole is tied together by the
front parts B and B (see Figure 13) the lower part Be having hooks h which
engage hooks 8 on the sides B₁, while the hooks h of the upper part B³ slide
under and engage other hooks 10 on the sides B¹.
The upper plates B³ and B are supported respectively by the plates B and B6,
the former one, B³, having hooks 12 which engage the upper edge of the plate B4,
while the latter plate, B5, enters a groove h¹¹ on the upper edge of the plate B.
When an apparatus is required with three or more courses or throats as is the
case with the construction shown in Figures 11 and 12, a controller such as that
shown in Figure 17 having a corresponding number of throats b, b¹, and 6¹ and
dampers 6, 63, 63 must be used. This controller is constructed in a manner
similar to the one B already described but with an additional partition B3 adapted
to be held in place between suitable cheeks.
Obviously the apparatus as described will form an efficient ventilator, and for
that purpose an opening or funnel-piece such as the one shown in dotted lines
at E may be added. This opening E will run into the room or apartment to be
ventilated and it will be apparent that the upward current following the direction
of the arrows 1 and 2 will suck up with it the vitiated atmosphere or the like.

page_text: Again it will be apparent that in many ways the apparatus will constitute an
efficient smoke cure. For example it will be seen that it entirely encloses and
contracts the passage between the fireplace and the up-take, rendering the draught
sharper.
Having now particularly described and ascertained. the nature of my Baid
invention and in what manner the same is to be performed, I declare that what
I claim is;-
1. A controller such as B constructed with two or more throats each provided
with an independent damper substantially as and for the purposes set forth.
2. A controller such as B so constructed that its parts interlock and interfit
substantially as set forth.
3. The combination, with a controller such as B constructed with two or more
channels each provided with an independent damper, of a hood such as C provided
with a damper such as c.
4. The combination, with a fire-place, of a chamber, alternative courses or
channels abutting said chamber and a controller such as B having independent
throats each in connection with one of said courses or channels and each throat
having a damper whereby the course of the products of the heating or like agent
may be directed or controlled substantially as and for the purposes set forth.
5. The combination, with a fire-place and a chamber having alternative courses
or channels abutting it, of a controller such as B and a hood such as C substan-
tially as and for the purposes set forth.
6. The combination, with a fire-place, of a heating chamber divided into two or
more parts, or of two or more separate heating or like chambers or distributors,
substantially as set forth.
7. The improved heating, ventilating and draught-regulating apparatus con-
structed substantially as set forth and as illustrated in the accompanying drawings.
