THE INVENTION OF A NINNEsOTIAN-H HOW 1T
WILL GET Up HILL.
from the 81. Paul (Minp.) Pioneer Press Feb. 20
During the winter months Professor Sa-
Toni has been busy in perfecting his steam
wagon, and he will this week forward his
model Of the machinery TO Washington, ID.
c., for the purpose of securing letter s.Da-
tent upon il, he having 80 far been operating
under a simple caVeat. Since the appear
ance OF the apparatus upon the streets last
fall II has been vastly improved. By a
double system Of clutches aud 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 no.
velty that has been introduced into the ma
chinery is a system of propulsion for use
in case OF ascending q steep hill. Taking
an idea from the fact that a horse car can
draw much heavier load than it's own
weight. the inventor has introduced two
sets OF levers that correspond exactly in
movement and in the application OF power
with the two bind legs Of a horse, the one
alternating with the other, precisely as do
the limbs OF the animal. IL is difficult,
! without diagrams, to illustrate how this is
accomplished, but lis effect can be under
stood with sufficient cIearness from the
foregoing comparison. The second impor-
tant advance made is in device for the
rapid generation OF steam, which is a mar
vel OF ingenuity, as we'll as marvel OF sue
cess. As formerly, gasoline Is the fuel en-
pOyed, and the flame is made TO play
upon pumce- stone, which heats TO a white
ness. and thus not only creates reservoir
of constant heat, but should the flame be
| temporarily eXtingushed by sndden jerk

StanIly rekindled. The pumice-stone Oc-
cupies the tire-bOX, above which are ar
ranged coils OF pipe containing the water.
which are so arranged as to give the water
both lateral and longitudinal motion, ald
| to permit the sediment TO settle in the lower
pipes on the side OF the fre-boX, where IL
can be readily taken out. A second and
smaller boiler is used to generate steam
| first, and this superheated steam is con-
Quoted 10 q nozzle, at the end Of which
and below it is placed closely a sec-
ond nozzle. This portion OF the ap-
paratus is similar 10 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 a perfume
bottle. The Jet OF superheated steam as il
emerges from its nozzle meets Jet OF gaso-
line vapor from the nozzle immediately be.
low the stelm-nozZle, and steam and gas are
together projected into the fire-boX in that
| infinitely divided condition so favorable to
chemical combination, resulting in intense
combustion and the rapid production OF
heat. As soon as the pumicc-stone has thus
been sufficiently heated the atOmizers are
shut off and the ordinary service.iets are
turned on. BY this means steam can bt
generated from cold water to pressure o.
! 100 pounds in four minutes. 1t may b'
added that the "leg propulsion," if it may
be so termed, can be used with or wiihou
the slow-motlon pulley, or the locomotive
apparatus may be entirely uncoupled, an(
the power applied to driving tbreshing
machine, with the wagon remaining sta
| tionary.
