JOSEPH HoADnBx's MOTOR
a Successful Test Made I'm Wash-
ington.

WASHINGTON, April 81. = Receiver
Sohoepf and his engineers have pro-
nounced the recent test OF the Hosdley-
Knight air motor on the cars OF the
lexington and Soldiers Hons road TO
have been a perfect success, and that
line will be Immediately equipped with
the new machines.
Joseph HoRdley, inventor of the
motor and President of the Hoadley-
Knight Air Motor Company, is San
Francisco boy, aud began his meohsni-
cal career in that city at the Union
Iron Works. Later he became a con-
tractor and machinery expert, and he
and his brother Albert put in many ex-
sensive steam and power plants, notably
that of the Chronicle building. From
San Francisco they went to Los Auge-
les and put down the cable lines there.
Subsequently they constructed traction
rosds In Chicago, New Haven and Day
ton, o.
While engaged In this labor they be-
came interested in the development of
compressed air motors. The patents of
Knight were developed and brought TO
sheir present state OF perfection and the
brothers formed a company, Interesting
as stockholders such men as " Fl Ell
kius, P Widener. Charles F Yerkes,
Dsniel Lamont end William Whitney,
ell of whom are behind the systems in
New York, Philadelphia and Chicago.
The first test CT the motors was made
on the Fourth-svenue line in New York
and was SO successful that that road is
now being equipped with them. These
tests attracted the RtteD ton OF Charles
F Orocker, and the San Francisco man
investigated thu motor with view to
using / on the Market street system in
that city. There were many teets of
the capacity of the motor to work un-
der the conditions which would be met
| in San Fran cisco, and ID Is understood
that the impression made wssfavorable.
It is probable that the first opening TO
be given to the new power will be on
| the Cliff House and Ferries Inns. It
| would take the plscs OF the steam en-
gines now in use. with the advantage OF
greater eoouomy in operation as we'll SIS
| noiselessness and perfection of control
| and freedom from danger Of explosion
The speed OF the motor to be used
| upon the lexington line Is practically
| unlimited. The reservoirs, OF "bottles,' y
as they are called by the operators, are

sure of 1000 pounds when in actual USE
Each motor carries thirty-six of these
bottles IS al equipment. They are
placed beneath the seats and the plat
forms. The pressure is reduced down
to She motor automatically, and with 8
pressure Of few hundred pounds the
car runs equally as well, if not better,
than when it has bsen freshly charged.
Such oars as are TO be used on the Eek
ington line will run fifteen miles with
one filing of the reservoirs.
1t costs practically no moro TO lay 8
track fog the motor system than it did
for the old horse csrs, slightly heavier
rail being the only change.
"Ljquefed air will be the next move
msnt in this direction said MF. Hosd-
ley when discussing the motor, and q
bucketful will run car 200 miles. It
is comparatively easy So obtain cupful
now, but il larger quantities it would in
volve too much expense by the present
mode OF obtaining if, and ohespness is
the chief aim of the compressed air mo-
tor. We are perfectly eatisfed With sll
our tests, end are amazed as the posi-
bilities shey have opened up"-Ssn
