JOSHUA KIDD, of No. 12, Dartmouth Street, Westminster, Gas Engineer. IM-
PROVEMENTS IN APPARATUS FOR THE MANUFACTURE OF GAS FOR LIGHTING AND
HEATING PURPOSES."
My present Invention is an improvement on an Invention patented by me and
dated February 13th 1875, No. 531, for improvements in the manufacture of gas.
My improvements consist in combining with the gas produced there described a
carburetting apparatus together with ascending and descending pipes for cooling the
gas, and also combining with the said apparatus a small portable steam boiler for
generating the necessary steam for the jet c, this boiler must be heated by a gas
or oil flame, or any other heating agent that will give out a steady unvarying heat.
In carrying out my Invention I make a furnace similar to the furnace described
in the Specification attached to the aforesaid Patent, but in lieu of the coil c I use a
This boiler
small portable boiler for generating the steam required for the jet c.
should be heated by a gas or oil burner so as to give off a regular flow of steam to
the jet. The gas after it leaves the furnace at the outlet g passes up an ascending
and down a descending pipe; the gas being cooler in the descending pipe acts as a
syphon and increases the pressure. The gas after being cooled passes through a
carburetting apparatus of any desired form or internal arrangement, after which it
is ready to be used for lighting purposes. The gas before it is carburetted is non-
luminous, and may be used for cooking or heating purposes, the carburetting
material should be shale or petroleum spirit, such as is now used in air gas machines.
A varying supply of spirit may be supplied to the carburetter by means of a tank
capable of being either raised or lowered. A little cotton wick should be placed in
some part of the pipe leading from the tank to the carburetter so as to check the
flow of spirit; if, say, 20 lights are required by elevating the tank a given height
just sufficient spirit will be delivered to the carburetter to carburet this number of
lights; if more lights are wanted the tank must be raised; if less lights, it should be
lowered. I place a recepticle or chamber in the pipe between the gas producer
and the carburetting apparatus to collect any dust that may be blown over from
the producer.
What I wish to claim as my Invention is,-
The combination of a separate steam generator with the gas producer shewn in
My Snasification.

page_text: Second. The combination of a portable steam boiler heated by gas or oil, with a
carburetting apparatus and gas producer as described.
Third. The combination of one or more ascending and descending pipes, with a
carburetter and portable gas producer, all substantially as described.
Fourth. The method of supplying varing quantities of liquid hydrocarbon to a
carburetter.
Fifth. The method described of generating the gas under pressure so that its
own pressure will force it through pipes and enable the gas to escape from a jet or
jets with sufficient force to induce or carry with it the necessary air for its com-
bustion.
