COMPRESSED OIL GAS FOR LIGHTING CARS, STEAMBOATS, AND BUOYS.
We give in the accompanying figures the arrangement of the different
apparatus necessary for the manufacture and compression of illuminating
gas on the system of Mr. Pintsch, as well as the arrangements adopted by
the inventor for the lighting of railway cars and buoys. This system has
been adopted to some extent in both Germany and England, and is also
being introduced into France.

PLAN.]
The Pintsch gas is prepared by the distillation of heavy oils in a
furnace composed of two superposed retorts. The oil to be volatilized
is contained in a vertical reservoir B, which carries a bent pipe that
enters the upper retort, A. The flow of the oil is regulated in this
conduit by means of a micrometer screw which permits of varying the
supply according to the temperature of the retorts. In order to
facilitate the vaporization, the flow of oil starts from a cast-iron
trough, C, and from thence spreads in a thin and uniform layer in the
retort.
