4 Steam ROad.WagOn.

During the winter months Professor
Saroni has been busy in perfecting his
steam wagon, and he will this week for
ward his model of the machinery to
Washington, D. c., for the purpose of
securing letters patent upon it, he having
so far been operating under simple
caveat. Since the appearance of the ap-
paratus upon the streets last fall it has
been vastly improved. By double sys-
tenn of clutches and pulleys, one at each
end of the driving shaft, the power can
be applied for speed or for slow work
with heavy draught. But the greatest
novelty that has been introduced into the
machinery is system of propulsion for
use in case of ascending q steep hill.
Taking an idea from the fact that horse
can draw much heavier load than its
own weight, the inventor has introduced
two sets of levers that correspond exactly
in movement and in the application of
power with the two hind legs of horse,
the one alternating with the other, pre-
cisely as do the limbs of the animal. 1t
is difficult, without diagrams, to illustrate
how this is accomplished, but its effect
can be understood with sufficient clear
ness from the foregoing comparison.
The second important advance made is
in device for the rapid generation of
steam, which is marvel of ingenuity, as
we'll as marvel of success. As former
ly, gasoline is the fuel employed, and the
fame is made to play upon pumice-stone,
which heat to a whiteness, and thus not
only creates reservoir of constant heat,
but should the fame be temporarily ex-
tinguished by sudden jerk of the ma
chinery, as it is apt to be, it is rekindled.
The pumice-stone occupies the 6re-box
above which are arranged coils of pipe
containing the water, which are so ar
ranged as to give the water both lateral
and longitudinal motion, and TO permit
the sediment to settle in the lower pipes
on the side Of the fre-box, where it can
be readily taken out. A second and
smaller boiler is used to generate steam
first, and this super-heated steam is con-
Quoted to a nozzle, at the end of which
and below it is placed closely a second
nozzle. This portion of the apparatus is
similar to the atomizers which are so
familiarly known and used in procuring
fine spray from bottles of perfume, and
the action of the steam atomizer invented
by Professor Saroni is precisely similar
to that of q perfume bottle. The jet OF
superheated steam, as it emerges from its
nozzle, meets a jet of gasoline vapor from
the nozzle Immediately below the steam
nozzle, and steam and gas are together
projected into the fire-box in that infin-
itely divided condition so favorable to
chemical combination, resulting i'll in
tense combustion and the rapid produc-
tion of heat. AS soon as the pumice-
stone has thus been sufficiently heated,
the atomizers are shut off and the ordi-
nary service jets are turned on. By this
means steam can be generated from cold
water to pressure of 100 pounds in four
minutes. It may be added that the ''leg
propulsion" if it may be so termed, can
be used with or without the slow-motion
pulley, or the locomotive apparatus may
be entirely uncoupled, and the power ap-
piled to driving a thrashing-machine,
with the wagon remaining stationary
