and for this reason the production of a spheroidal state of the liquid is
avoided. It consists of a vessel, 44, into which the liquid is led by a
pipe, 43. The cast-iron evaporating vessel, 14, is provided with
appendages, 14 _bis_, which dip into the liquid and bring about its
evaporation. A refractory clay sleeve, 41, protects the lower part of the
cylinder, 15, from the fire, and diminishes the smoke passages at 42. The
vapor produced makes its way vertically through a layer of charcoal
placed between the evaporating vessel, 14, and the receiver, 17, and
serving to decompose the aqueous vapor formed.

All clay and red and white lead joints are done away with in this part of
the apparatus, as are also packing bolts. Thus, at the upper part the
cover, 19, is provided with a rim that enters a cavity filled with lead,
so, too, the lower part of the evaporating vessel, 14, rests in a channel
containing lead. There is also at 30, a joint of the same character for
the rim of the external cylindrical vessel, 18. Both this latter and the
receiver, 17, dip beneath into a tank of water, 66.

The distributer, B, is so arranged as to cause the water, and oil, and
the liquids to be vaporized to flow with the greatest regularity, and
proportionally to the consumption of the gas in cases where the latter is
not stored up in a gas meter. The flow is controlled by cocks that are
actuated by variations in the height of the regulator receiver. All the
condensation that occurs in the various parts of the apparatus collects
in a receptacle, 52, so arranged as to perform the office of a separator
and set apart the oil at 20, and the water at 21, through the natural
effect of their difference in density. This latter is likewise utilized
for causing the oil to flow into the vaporizer through 26 and 27, instead
of using a graduated cock that receives a variable pressure from the
receiver. In this way every cause of obstruction is avoided.
