We, JAMES FOORD of No 276 Portobello Road Gas Engineer and WILLIAM
WREFORD PADDON of No 34 St Charles Square Gentleman both in North
Kensington London do hereby declare the nature of this invention to be as
follows:-
This invention has for its object improvements in apparatus for carburetting air
to be employed in lieu of coal gas in obtaining light and heat.
We make use of a current of air set in motion by a ventilating shaft passing
from top to bottom of the building to be lighted. Heated air is allowed to pass
into this ventilating shaft from any convenient points where, for the purpose of
ventilation, openings are provided for the escape of vitiated air from the several
rooms of the house. Usually the openings will be in the ceiling of the room
immediately over the gas burners: they will be concealed by a perforated rosette.
In the ventilating shaft there is a fly similar to a smoke jack, and this puts in
motion an horizontal axis, the ends of which project into two carburetting vessels,
one on either side. Within the carburetters the axis carries agitating wheels by
which the hydrocarbon liquid is put in motion-these wheels take the place of the
wheel put in motion by the current of air and the descent of the liquid as
previously described. The draught of air in the ventilating shaft is also made use
of to carry the requisite supply of air into the carburetters to afterwards pass to
the burners and be burnt in combination with the hydrocarbon vapour. A portion
of the air current is intercepted for this purpose at the entrance to the ventilating
shaft where the draft is strongest. We prefer as the current enters the ventilating
shaft at its lower end to divide it into two parts, one of which passing through the
fly or jack puts it in motion and so agitates the liquid hydrocarbon as previously
explained, whilst the other portion of the air enters the carburetters and from
thence passes on to the gas burners.
When it is desired to prepare the mixture of air and hydrocarbon vapour on a
large scale, as for lighting a village or town, gasometers of large dimensions are
employed, and the hydrocarbon oil is contained in tanks or wells in which it is

The air
from the gasometer passes into the tank or well and is brought into intimate
contact with the hydrocarbon vapour in the state of spray-the air being thus
charged with vapour is allowed to deposit any excess which in the first instance it
may take up, and is then passed into the mains by which it is delivered to the
consumers.

Improvements in Apparatus for Carburetting Air to be Employed
in Lieu of Coal Gas in Obtaining Light and Heat.
We JAMES FOORD of 276 Portobello Road Gas Engineer and WILLIAM
WREFORD PADDON of N° 34 St Charles Square Gentleman both in North
Kensington London 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:―

DESCRIPTION OF THE DRAWINGS.
Figure 1 is a vertical section of apparatus arranged in accordance with our
invention.
Figure 2 is a vertical section on the line A. A. in Figure 1. and
Figure 3 is an borizontal section on the line B. B. in Figure 1.
a is a ventilating shaft passing up through the building and having an opening
at the roof, air also is allowed to enter freely at its lower part at a¹. a³ is one of a
series of passages by which hot vitiated air is allowed to pass from the rooms of
the building to the ventilating shaft. a³ is a baffle plate at the lower part of the
shaft a intercepting a part of the incoming air and directing it into a pipe or
passage b.
61 is a damper in this passage by which the air current may be
regulated. c is a fly resembling that of a smoke jack arranged in the shaft a, it
is put into motion by the air current. Upon the upper end of the vertical axis of
the fly c is a bevilled pinion gearing with another similar pinion d' on an
horizontal axis d. The ends of the axis d project out from the shaft a into an
annular chamber e which surrounds this shaft. The chamber e is partly filled
with petroleum spirit or other carburetting liquid. * is the filling pipe closed at
the top with a screw plug. e** e** are gauge glasses to show the height of the
liquid in the vessel. ff are a pair of paddle wheels kept in rapid motion by the
smoke jack apparatus, they agitate the liquid in the chamber and bring it into
contact with the air which the chamber also contains and which is led into it by
the pipe b. The air entering the chamber e at b has to pass almost completely
around it to reach the outlet which is at g.
o
There are two partitions e¹ and e* in the chamber e, that at e³ is perforated and
allows the air to pass. The outlet pipe at g is in direct communication with the
burners at which the carburetted air is burnt as coal gas is usually burnt. We
prefer to employ two qualities of carburetting liquid one having a lower boiling
point than the other. The part of the divided chamber e which the air first
traverses we charge with the more volatile liquid and the other with the less
volatile.
To prepare carburetted air on a large scale we place the carburetting liquid in
large closed tanks or wells containing dash wheels driven by steam power so that
the said receptacles may be constantly filled with a spray of the liquid.
By means of weighted gasometers as already mentioned or by other air forcing
or suction apparatus air is passed through these tanks and thence into the mains
which supply the district as coal gas is usually distributed.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:-
L-The combination of apparatus consisting of a ventilating flue, a fly in the
said flue put in motion by the draft; a closed vessel containing carburetting
liquid, agitating apparatus in this vessel driven by the fly and means for
conducting air through the vessel to burners at which the carburetted air is
burnt.

page_text: 2. The combination of apparatus consisting of a ventilating flue; a closed
vessel containing carburetting liquid and a passage connecting the flue with the
interior of the vessel so arranged as to divert a portion of the draft of the flue and
apply it to propel air through the vessel and so to the burners at which the
carburetted air is burnt.
3. Apparatus substantially as represented by the annexed drawings for
carburetting air to be employed in lieu of coal gas in obtaining light and heat.
4. The combination of apparatus for carburetting air to be employed in lieu of
coal gas and consisting of closed tanks or wells containing mechanical agitators
and charged with carburetting liquid; gasometers or other apparatus propelling
air through the tanks or wells and main pipes by which the carburetted air is led
to the district to be supplied.
