Improvements in Carburettors.
We HAROLD COLLET of 7 Coleridge Road, Finsbury Park, N. Engineer and
MOSKA MERICHENSKI, of 1 Bruce Castle Road, Tottenham, N. Engineer, do
hereby declare the nature of this invention to be as follows:-
The present invention embodies a construction of carburettor which is intended
either to carburet atmospheric air so as to produce an inflammable gas capable of
being used for heating, lighting and motive power purposes, or to enrich ordinary
coal-gas or other gas, so as to increase its illuminating power.
The improved carburettor is automatic in its feeding action, that is to say the
hydrocarbon or other liquid substance employed is supplied to a reservoir from
which it is automatically fed in proportion to the consumption. The air to be
carburetted or the gas to be enriched is caused to travel through an extensive
channel and during such travel it mingles with the hydrocarbon vapor and becomes
carburetted; the channel is so devised that its walls are at all times evenly
saturated with hydrocarbon, so that the carburetting action is constantly uniform
and the air or gas is always carburetted or enriched respectively to a uniform
degree, without in any way having to depend either upon any regulation of the
supply of hydrocarbon or upon any adjustment of the inlet opening for the
atmospheric air or gas to be subjected to the action of the apparatus.
The carburettor is chiefly composed of an outer vessel preferably cylindrical and
made of any suitable material, and provided with a cover which is made gas-tight.
Into the vessel is placed a body which we will call the distributor and which has
for its object to distribute the liquid hydrocarbon and present it evenly to the air,
so as to enable it to mingle therewith and form carburetted air. The distributor
has a central chamber which always contains an almost constant quantity of hydro-
carbon. Its outer vertical surface is channelled and the channel begins at the inlet
pipe for the air to be carburetted or the gas to be enriched, then it descends,
passes horizontally at the bottom, then upwards, then horizontally at the top and
then it continues following a similar course until it reaches the outlet pipe, from
which the carburetted air is led to the spot of consumption by a pipe provided with
a cock. The hydrocarbon contained in the chamber passes through the distributor
which is made of wood, and oozes out at the external surface of the said distributor,
where it is met by the inflowing air circulating through the channel and mingles
therewith. The hydrocarbon which thus presents itself at the inside walls of the
channel mingles with the air, as above stated, is carried away therewith and is
replaced by fresh hydrocarbon oozing through the distributor, but any hydrocarbon
which oozes through at the outer surface of the vertical ribs between the channels
and at the horizontal ribs at the top and bottom of the distributor is taken up by a
porous or absorbing jacket interposed between the outer vessel and the distributor.
The jacket may be made of wood, or say other substance capable of making an
air-tight packing or joint. The air to be carburetted or the gas to be enriched
enters the apparatus through a pipe made gas-tight in the cover and provided with
a cock.
The supply of liquid hydrocarbon is contained in a closed vessel connected at the
top to a funnel provided with a cock and at the bottom to a pipe provided with a
cock. The pipe is screwthreaded and is screwed into a bush which is secured gas-
tight into the cover; it can be adjusted as to height, so that its lower end may be
made to dip more or less into the liquid hydrocarbon contained in the chamber.
When once properly adjusted, the said pipe leading from the vessel is set by means

page_text: of a nut, a suitable washer being interposed between the bush and the nut for the
purpose of obtaining a gas-tight joint.
The hydrocarbon supplied to the chamber in the distributor will gradually travel
in all directions through the pores of the distributor until it reaches the compound
channel at its outer surface. As soon as the hydrocarbon descends below the
almost constant level at or near the bottom end of the feed pipe, it is replaced by
fresh hydrocarbon from the vessel and so on as long as the vessel is kept supplied.

Improvements in Carburettors.
We, HAROLD COLLET, of 7 Coleridge Road, Finsbury Park, N. Engineer, and
MOSKA MERICHENSKI, of 1 Bruce Castle Road, Tottenhain, N. 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:
The present invention embodies a construction of carburettor which is illustrated
in the accompanying diagrams.
Fig. 1 is a vertical section, and
Fig. 2 is a plan of the carburettor.
Fig. 3 shows the hydrocarbon distributor supposed laid out flat.
Fig. 4 is a plan of Fig. 1. on the line 1. 1
Fig. 5 is a plan of Fig. 1, on the line 2, 2.
The carburettor is intended either to carburet atmospheric air so as to produce
an inflammable gas which can be used for heating, lighting and motive power
purposes, or to enrich ordinary coal-gas, or other gas, so as to increase its illuminating
power.
The improved carburettor is automatic in its feeding action, that is to say, the
hydrocarbon or other liquid substance employed is supplied from time to time to a
reservoir from which it is automatically fed through a distributor in proportion to
the consumption. The air to be carburetted or the gas to be enriched is caused to
travel through an extensive channel and during such travel it mingles with the
hydrocarbon vapor and becomes carburetted; the channel is so devised that its
walls are at all times evenly saturated with hydrocarbon, so that the carburetting
action is constantly uniform and the air or gas is always carburetted or enriched,
respectively, to a uniform degree, without in any way having to depend either upon
any regulation of the supply of hydrocarbon or upon any adjustment of the
inlet opening for the atmospheric air or gas to be subjected to the action of
the apparatus.
a is an outer vessel, preferably, cylindrical, made of any suitable material, and
provided with a cover b which is made gas-tight. Into the vessel a is placed a
body which I will call the distributor and which has for its object to distribute
the liquid hydrocarbon and present it evenly to the air, so as to enable it to mingle
therewith, and form carburetted air. The distributor c has a central chamber d
which always contains an almost constant quantity of hydrocarbon; its outer
vertical surface is channelled at e, as shown in Fig. 3 which for the convenience of
illustration, illustrates the said surface laid out flat, the beginning and end of the
development proceeding from a radial line x, x Fig. 4 & 5. The channel e begins
at the inlet pipe f for the air to be carburetted or the gas to be enriched, then it
descends, passes horizontally at g; then upwards, then horizontally at h and then it
continues following a similar course until it reaches the outlet pipe i, from which the
carburetted air is led to the spot of consumption by a pipe j, provided with a cock k.
Fig. 5 is a plan of Fig. 1, on the line 2, 2.
The carburettor is intended either to carburet atmospheric air so as to produce
an inflammable gas which can be used for heating, lighting and motive power
purposes, or to enrich ordinary coal-gas, or other gas, so as to increase its illuminating
power.
The improved carburettor is automatic in its feeding action, that is to say, the
hydrocarbon or other liquid substance employed is supplied from time to time to a
reservoir from which it is automatically fed through a distributor in proportion to
the consumption. The air to be carburetted or the gas to be enriched is caused to
travel through an extensive channel and during such travel it mingles with the
hydrocarbon vapor and becomes carburetted; the channel is so devised that its
walls are at all times evenly saturated with hydrocarbon, so that the carburetting
action is constantly uniform and the air or gas is always carburetted or enriched,
respectively, to a uniform degree, without in any way having to depend either upon
any regulation of the supply of hydrocarbon or upon any adjustment of the
inlet opening for the atmospheric air or gas to be subjected to the action of
the apparatus.
a is an outer vessel, preferably, cylindrical, made of any suitable material, and
provided with a cover which is made gas-tight. Into the vessel a is placed a
body e which I will call the distributor and which has for its object to distribute
the liquid hydrocarbon and present it evenly to the air, so as to enable it to mingle
therewith, and form carburetted air. The distributor c has a central chamber d
which always contains an almost constant quantity of hydrocarbon; its outer
vertical surface is channelled at e, as shown in Fig. 3 which for the convenience of
illustration, illustrates the said surface laid out flat, the beginning and end of the
development proceeding from a radial line, Fig. 4 & 5. The channel e begins
at the inlet pipe f for the air to be carburetted or the gas to be enriched, then it
descends, passes horizontally at g; then upwards, then horizontally at h and then it
continues following a similar course until it reaches the outlet pipe i, from which the
carburetted air is led to the spot of consumption by a pipe j, provided with a cock k.

page_text: The hydrocarbon contained in the chamber d passes through the distributor c
which is made of wood, and oozes out at the external surface of the said distributor,
where it is met by the inflowing air circulating through the channel e, and mingles
therewith. The hydrocarbon which thus presents itself at the walls of the
channel e mingles with the air, as above stated, is carried away therewith through i
and is replaced by fresh hydrocarbon oozing through the distributor c, but any
hydrocarbon which oozes through at the outer surface of the vertical ribs between
the channels e and at the horizontal ribs m, n at the top and bottom of the
distributor is taken up by a porous or absorbing jacket o interposed between the
outer vessel a and the distributor c. The jacket o may be made of wood, cloth,
felt, porcelain or any other substance, capable of absorbing liquid hydrocarbon by
capillary attraction. The air to be carburetted or the gas to be enriched enters
the apparatus through a pipe p made gas tight in the cover and provided with a
cock q.
The supply of liquid hydrocarbon is contained in a closed vessel r, connected at
the top to a funnels provided with a cock t, and at the bottom to a pipe u provided
with a cock r. The pipe u is screw-threaded and is screwed into a bush w which is
secured gas-tight into the cover b; it can be adjusted as to height, so that its lower
end may be made to dip more or less into the liquid hydrocarbon contained in the
chamber d. When once properly adjusted, the pipe u is set by means of a nut y,
a suitable washer being interposed between the bush w and the nut, for the purpose
of obtaining a fluid-tight joint.
The action of the apparatus is as follows: Liquid hydrocarbon is supplied into
the closed vessel r, first closing the cock and opening the cock t. The cock t is
closed & the cock is then opened and a quantity of hydrocarbon will descend by
gravity through the pipe into the chamber d, after which the well known
phenomena will take place, viz.: as soon as a vacuum is formed above the liquid in
the closed vessel r, the liquid will momentarily cease to flow until one or more
bubbles of air rise from the chamber d through the pipe u into the vessel r. The
liquid will then again begin to flow downward and so on until the chamber d gets
filled up to a level reaching somewhat above the bottom end of the pipe u. The
hydrocarbon supplied to the chamber d will gradually travel in all directions
through the pores of the distributor until it reaches the compound channel e at its
outer surface. As soon as the hydrocarbon descends below the almost constant
level at or near the bottom end of the feed pipe u, it is replaced by fresh hydro-
carbon from the vessel t, and so on as long as the vessel is kept supplied.

The cock g of the inlet pipe p is then opened and atmospheric air or gas
introduced into the apparatus, the air or gas will find its way through the pipe f
into the compound channel e and become saturated with hydrocarbon vapor as it
travels through the said channel. During such passage, the said air becomes
not only saturated with the hydrocarbon vapor which evolves at the three
walls 1, 2, 3 Fig. 5 of each vertical channel e of the distributor c, but also by the
hydrocarbon which as hereinbefore stated, has been absorbed by and evolves as
The carburetted
vapour at the inner surface or wall 4 of the absorbing jacket o.
air or enriched gas issues from the apparatus through the pipe i and is conveyed
away by the pipe j, the cock k having been previously opened.
The operation of the apparatus having now been explained, it is to be remarked
that the walls 1, 2, 3 of the distributor c, Fig. 5 as well as the walls 4 of the
jacket o are at all times evenly saturated with hydrocarbon and thus the production
of gas is uniform. It is also to be remarked that by adjusting the position of the
supply pipe, the head or column of hydrocarbon in d can be made to vary; the
degree of saturation of the distributor c can thus be regulated to some extent.
Moreover, it is especially to be remarked that the chamber d can be made more or
less deep so as to cause the hydrocarbon to be distributed more towards the top
than at the center of the distributor c, with a view of radiating the hydrocarbon as
required towards all parts of the outer surface of the said distributor.
It is finally to be also observed that if the pressure of the gas or air introduced by

page_text: the pipe p into the apparatus increases slightly, the said pressure will tend to force
the head or column of hydrocarbon in d through the distributor c, so that the
amount of hydrocarbon exposed to the air being carburetted will be increased.
Thus if the atmospheric air or gas flows quicker through the channel e, a
proportionally greater amount of hydrocarbon will be subjected to the said air.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :
í-In a carburettor, a distributor c made of wood or other equivalent material,
capable of capillary attraction, through which liquid hydrocarbon is caused to pass,
substantially as described.
