Improvements in Apparatus for Manufacturing Oil Gas.
We, THE NORTHERN COUNTIES HYDRO-OXYGEN GAS Co. LTD., of 71, King
Street, Manchester, and PERCY BURKITT WATERMAN GOBLE, of Great
Marlborough Street, Oxford Street, Manchester, Engineer, do hereby. declare
the nature of this invention to be as follows:-
This invention relates to a construction and arrangement of furnace and retorts
for producing oil gas, such that the oil supplied to the retorts is cracked at an even
low temperature and that the produced gas is discharged directly and rapidly from
the retorts. For this purpose, each group of retorts consists of three or four each
placed at an inclination in the flue and connected at its end to the next retort
above it which is similarly inclined but in the opposite direction, so that the three
or four retorts thus combined form together a zig-zag channel. The oil is supplied,
preferably by a pipe or pipes projecting some distance into the highest retort,
which is downwardly inclined from the end at which the oil enters, and, when
there are four retorts, it may also be supplied to the second from the top which is
likewise downwardly inclined. From the lowest end of the lowest retort there is
an outlet into a receptacle for the tarry residue. From this receptacle on the one
side of the furnace and from a similar receptacle on the other side a pipe ascends
above the furnace and both these pipes join a cross pipe from which a branch dips
down into a hydraulic main.
To these two pipes there are branches from the ends of each pair of retorts, by
which the gas is led directly from the retorts as it is produced. Such oil vapour
as may accompanying the gas becomes condensed in the ascending pipes and the
condensed oil descends into the receptacles at the bottoms of the pipes. These
receptacles are from time to time emptied and the oil separated from the tar is
again fed to the retorts. A number of sets of retorts as above described, are
arranged side by side in furnace compartments, two or more of the sets in each
compartment, all of which are heated, preferably by the combustion of gas
generated in a producer below.

Improvements in Apparatus for Manufacturing Oil Gas.
We, THE NORTHERN COUNTIES HYDRO OXYGEN GAS Co. LTD., of 71 King
Street, Manchester, and PERCY BURKITT WATERMAN GOBLE, of Great
Marlborough Street, Oxford Street, Manchester, 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 :-
This invention relates to a construction and arrangement of furnace and retorts
for producing oil gas such that the oil supplied to the retorts is cracked at an
even low temperature and that the produced gas is discharged directly and rapidly
from the retorts. For this purpose the apparatus is arranged as shewn in transverse
section by Fig. 1 and partly in elevation by Fig. 2 of the accompanying
drawings.
Each group of retorts consists of four -R1 R2 R3 R4 each placed at an inclination
in the furnace chamber F which is supplied below with Hame and hot products of

page_text: combustion from a gas or other suitable furnace. Each retort is connected at its
end to the next retort above it which is similarly inclined but in the opposite
direction, so that the four retorts thus combined form together a zigzag channel.
The oil is supplied direct to the hydraulic main H being retained therein at a
constant level. From this it is drawn off at any convenient position and passes by
an oil main O into a funnel communicating by a siphon bend with a pipe o projecting
some distance into the highest retort R which is downwardly inclined from-the end
at which the oil enters, and, oil may also be supplied as shewn from another oil
main O¹ connected with the hydraulic main H to the third retort R³ which is
likewise downwardly inclined. From the lowest end of the lowest retort R there
is an outlet into a hydraulic main T forming a receptacle for the tarry residue,
and for such residues as may be condensed from the vapours in the vertical pipes.
From this receptacle on the one side of the furnace and from the lowest retort
on the other side pipes P ascend above the furnace and join a cross pipe P¹ from
which a branch P2 dips down into the hydraulic main H but not deep enough to
enter the oil in same.
The two pipes P communicate freely with the ends of the retorts so that the
gas is led by these pipes directly from the retorts as it is produced.
Such oil vapour as may accompany the gas, becomes condensed on coming into
contact with the surface of the oil in the hydraulic main H and mixing therewith
is fed into the retorts.
The receptacle T has in any convenient part of its length an outlet below the
water for tar subsiding under the water. A number of sets of retorts as above
described, are arranged side by side in furnace compartments, two or more of the
sets in each compartment, all of which are heated, preferably by the combustion of
gas generated in a producer below.
The flame and hot products of combustion pass through an opening in the roof
of the furnace chamber into the flue F' and thence to a chimney, the draught through
each furnace chamber being regulated by a damper G.
In the furnace chamber F two groups of the retorts are arranged (but there
may be a greater number) in parallel planes, all heated by the hot gases in the
chamber.
Although we have shewn only two retorts as being supplied with oil it is to be
understood that the apparatus can be so arranged that each retort is supplied with
oil at its upper end.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
Apparatus for manufacturing oil gas, consisting of groups of retorts arranged
one above the other in a furnace chamber, each inclined and communicating with
the next so that all of each group form a zigzag passage some or all of the retorts
having oil supply pipes projecting into them and all the retorts communicating at
their ends with pipes ascending to a hydraulic main, substantially as described.
