A STEAM TRICYCLE..
SUCCESSFUL TRIAL or A TRESoH IN
vESTioN.

WIS 0rNfIIUtu "" w WV NahsN
was presented 10 engineers ana tne
public. As Ia wellknown, u c ons,su
u capillary metallic tube, IN Wh'cn
water, whom injected Into ", ~ III ln
medIateIy converted Into steam. This
rsmarka6le generator, which contains
but few cubic centimeters OF water
and no steam In reserve, seems 70 ush
the very outset admirably adapted lot
satisfying certain exigencies, snu ~
peclaily those OF the economical and
practical propulsion o vehicles; A,tst
frst operating steam tricycle., MI.
Serpoilet has within the last lew year.
successfully constructed experimental
vehiclesshat have many timea been
operated At Paris, aud that In january,
1850, permitted him, n company WIN
Ernest Afchdeaconi TO make = long
trip 10 Lyons. These preliminary
students led the Inventor TO devise an
absolutely practical type that We pro-
pose 10 make known 10 our readers.
The carriage II handsome aud lux
urlous. The work, moreover, was
done by one ofour best specialists. ~
has the form Of large phacton anu IL
capable Of seating seven passengcrs--
three upon each seat aud one upon
bracket seat Just opposite. Nothing OF
the comfort iound In ordinary carriages
IL lacking In this. The suspension j.
easy aud the seats afc soft. In case OF
rain the hood In front can be put up a.
In other pbaetons.
The generator IL concealed from
yics. II Ia situated 10 the rear he.
tween the coal boxes, with which j.
connected by two passageways, through
which the fuel IL fed automatically.
The chimney IL Inverted. Another
chimney, used only for nring up, i
carried In box. The water tank Il
placcd under the seat 10 the left. The
supply Of water permits Of making n
trip of thirty kllomuicrs and tho supply
Of fuel permits of run Of sixty kilo'
meters. In cities the fuel 10 be pre-.
ferf,d Ia coke, on account ofthe absence
Of smoke. The total weight " the
carriage, charged with water and fuel,
IA 1880 Kilograms. n carries then
seventy Kilograms Of fuel and ninety
IL water. The mean vaporixation OF
tho generator Il eighteen Kilograms
per hour. The consumption per horse
and per hour docs not exceed fourteen
Kilograms.
The engine has two cylinders, the
eanks are keyed al right angles, aud
the admission ~ steam Il made nj %
Ter cent. The power which IL that Of
four horses, may momcniarily attain
that " ak. The arrangement OF the
transmission Il such that two speeds
may DO employed, one for gradient.
and the other for running on level.
With IN. latter aspecd OF twenty-five
kilometafs IN obtained and maintained
practically upon n good road. This
speed II would 10 imprudcnt 10 exceed
orovon nj times maintain. With the
other speed the carriage loaded with
its seven passengers has ascending
gradients OF eight ccntlmet.rs per
meter over heavy roads charged with
pebbles.
Firing upis effected A. IN ordinary
stoves, and In twenty minutes every
thing may 10 put Ia state for q trip.
The starting Il effected by means Of
hand pump. The water introduced
into the generator instantly vaporixes,
and tho carriage begin. 10 move. This
feeding continues automatically. The
steering handle serves al.o ~ regulate
tho speed. II IL capable Of making n
rotary motion upon It, axis aud Of
opening and closing an oriilce for tho
return Of the water 10 the tank. II To
quirrs but one hand for tho steering.
As with stationary geucratou, stop

The mnst sudden sloppago Ia effected
through brake with q pcial placed
within reach OF the diver. foot No
inspection apparatus Il necessary, and
II Il, therefore, possible las experience
has drmonstratedl 10 travel during the
darkest night with q simple lamp tot
lighting the roadway.
The carriage IL provided with a
pressure guage, which, without being
necessary, gives some very interesting
readings. II renders evident one OF
the great inertia Of tho Ssrpollct gene.
rator, and that Il IL cApabillty Of
reaching high prcuuroa instantaneous.
ly and without danger.
II, on throwing the carriage int
gear, u Il In atight place and pre-.

tinucd up 10 10, IL or 20 atmosphervs II

takes place spontaneously at tho very
moment that II II necessary, and that,

generators arc tested 10 100 atmos.

nro tested 10 300 NJ the works before the
test Of the administration Of mines.
There Il another interesting point Il
DO mentioned. According ms the car
riago Ia running on level OF up OF
down hill, the pressure, without ona'i
having 10 occupy himself with the mp
paratus, remains stationary or decendl
or rises Of Itself, according n the motto
meets with u greater OF lrsa RESISTANCE.
The pecullArltles Of the Srrpollel
generator explain the facility with
which n new effort may bo given /,
the motor Of tho carriage In difilcnl
Passages, either for avoiding an impe
dim~nt or for tIayorslng a bad road. A
simple supplementary Injection with
the hand pump suiilces 10 obtain th,
desired effect. The pressure rises, Ia,
quantity Of steam produced Increases
and the new stress Il exertcd as II by |
horse. No inspecllon.is necessary on
stopping aud no obstruction occurs II

Of tho water.
Mr.. Serpollet's steam carriages hay,
been authorized by the prefecture o
police 10 be run freely Ia Paris, with
single restriction, and that il the
must not exceed sixteen kllomelefs pc
