An Improvement in Apparatus for Enriching Gas by Admixture of
Hydrocarbon Vapour.
We, JAMES LIVESEY, of No. 2 Victoria Mansions, Westminster, in the County of
Middlesex, Civil Engineer and WILLIAM WHITEHOUSE of Empire Works, Bructon
Street, Birmingham, in the County of Warwick, Chandelier Manufacturer, do hereby
declare the nature of this invention to be as follows:-
In the specifications Nos. 2135 of 1880 and 1331 of 1881 are described apparatus
for enriching gas by admixture of hydrocarbon vapour. In these apparatus naphthaline
or hydrocarbon is fed into a carburetting vessel through a hole fitted with a screwed
cap, and the proportion of gas to hydrocarbon vapour is regulated by a separate three-
way cock, allowing more or less of the gas to pass through the vapour space of the
carburetting vessel.
Our present invention relates to a more simple and cheaper construction of such
apparatus. We make the opening through which the naphthaline is supplied as a
casing to receive the conical plug of a three-way cock. The gas supplied through a
nozzle by which the apparatus is connected to the service pipe is conducted up to
a lateral aperture in this casing, thence, when the plug is in one position the gas
passes through the plug to another aperture in the casing leading directly to the gas
burner. When the plug is turned to another position a groove in the plug is put in
communication with the passage to the burner, and by this groove vapour of the
naphthaline or hydrocarbon is permitted to mix with the gas in greater or less
proportion according to the position to which the plug is turned. The plug can be
moved by an external handle and is prevented by a suitable stop from being turned
too far round in either direction or from being dislodged from its casing.

An Improvement in Apparatus for Enriching Gas by Admixture of
Hydrocarbon Vapour.
We, JAMES LIVESEY of No. 2 Victoria Mansion's Westminster in the County of
Middlesex, Civil Engineer and WILLIAM WHITEHOUSE of Empire Works, Bructon
Street, Birmingham in the County of Warwick, Chandelier Manufacturer, 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:-
In the Specifications Nos. 2135 of 1880 and 1131 of 1881, is described apparatus
for enriching gas by admixture of hydrocarbon vapour. In this apparatus naph-
thaline or hydrocarbon is fed into a carburetting vessel through a hole fitted with a
screwed cap, and the proportion of gas to hydrocarbon vapour is regulated by a
separate three way cock, allowing more or less of the gas to pass through the vapour
spaces of the carburetting vessel.
Our present invention relates to a more simple and cheaper construction of such
apparatus. We make the opening through which the naphthaline is supplied, as a
casing to receive the conical plug of a three way cock. The gas supplied through a
nozzle by which the apparatus is connected to the service pipe is conducted up to
a lateral aperture in this casing, thence when the plug is in one position the gas passes
through the plug to another aperture in the casing leading directly to the
gas burner.
When the plug is turned to another position, passages in the plug are put in
communication with the carburetting vessel so that vapour of the naphthaline or
hydrocarbon is permitted to mix with the gas in greater or less proportion according
to the position to which the plug is turned. The plug can be moved by an external
handle, and is prevented by a suitable stop from being turned too far round in either
direction or from being dislodged from its casing. Fig. 1 of the accompanying
drawings is a vertical section of the carburating vessel with its plug in the position
for passing the gas direct to the burner, Fig. 2 is an elevation partly in section
shewing the plug in position for conburating the gas. Fig. 3 is a sectional plan of
the plug and its passages. A is the carburating vessel which is charged with
naphthaline N or other suitable hydrocarbon, introduced into the vessel by the hole
fitted with the plug P. This plug is made with a passage B directly through it and
two passages C and D opening downwards; and it is held in its seat and stopped in
each direction by a stud working in a bayonet catch slot E. In one position of the
plug, as shewn in Fig. 1, the gas from the service pipe S, passes up the bent pipe G
through the direct Passage B to the pipe H which leads it to the burner L. In
another position of the plug as shewn in Figs. 2 & 3 the gas from G is directed by the
passage into the upper part of the vessel A which is occupied by hydrocarbon vapour,
portion of which mingles with the gas. The mixture flows by the passage D and the
pipe H to the burner L. The extent to which the gas is carburated can be regulated

page_text: by turning more or less the plug P so as to direct more or less of the gas by the
passages and D. Heat is communicated to the vessel A in the usual way by
radiation from the flame and by conduction of the heat imparted by the products of
combustion to the projecting bracket M. When the vessel A has to be charged, the
plug is turned to the position such that the stop stud is free to be withdrawn from the
bayonet notch E, and then the plug can be taken out leaving its seating open for
introduction of the hydrocarbon.
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 :-
In apparatus for enriching gas by admixture of hydrocarbon vapour, constructing
the charging plug as a cock with passages arranged for regulating carburation of the
gas substantially as herein described.
