II is thought that the bullet by this time
has become incysted-that is, sac has
formed around it, which may prevent any
return OF the dangerous ailments. Miss
Newhart is now fifteen years of age.
Gas Motor Car Service in Dresden.
About one year ago, witnessed triaI
trip of a gas motor car in this city, ana
since that time J have watched the progress
and Improvements that have been nade-
and am now able, with the aid OF informa-
ton obtained from Mr.. ] Ohm Young, super
intcndcnt OF the Gas Traction Company
Limited), London and Dresden, to report
that the mot or during the first trial trip
worked fairly well. but showed some de-
ficiencies, apparently in its mechanical
construction, and that since that time
those Deficiencies have been remedied, ana
during later trial trips the motor car has
proved entirely satisfactory.
At the first trial the car always started
with a noticeable Jerk and did not run
smoothly: and when not in motion, CON
siderable qua nifty of gas was used 10 keep
the motor running. causing he car To sway
and trcmbe: the clutch coupling did not
work regularly and broke easily; the ear
was clumsy and msighlly. All these OH
jections have apparently been overcome,
ana an easy. mdndptdiilt, ttpiioiIli'dl iiip
tor for public traffic is the r"sn't.
This car weighs D IL German tons
(about f2.121 English pounds. The dis
tance between the wheels Is Loo metres
Iabout > feet lD,hcsl. and the length OF
the car frame is 80 metres tabout i feet
. inchcsy. There are IA inside seats, 10
on both platforms. and l Q on top of the
car, making a total capacity OF SO seats.
The car has a gauge OF 1.433 metres
a haE no NJ
pearsnCe OF an ordinary street car, eN-
cepting the Two folding doors in the center
OF one side of the car, which cover the
driving wheels.
The motor has 10 horsepower, with
two cylinders. which are placed TN line
under one of the rows of seats, one on each
side OF the shaft.
The gas in the machine Is ignited 10y cleo
tricity without any noise, Two cylindrical
gaS tanks are fixed parallel with the axles
OF the wheels under the floor Of the car;
third gas II nls Is placed lengthways under
the row of seats opposite he ma Chincry and
serves As Il proper balance to the car.
These three gas tanks hold about o.so
cubic metre 1885 feet Of gas, and weigh
about $50 kilograms 1851 pounds. The
water used in cooling the cylinders Srcu-
lates automatically through copper tubes
eight-teDths OF millimetre 90 .O3lo
inches) thick, which run from the top to the
bottom OF the car in n spiral shape. The
water. when heated, rises To the top OF
these tubes. where it Cools and then flows
back into the gas cylinders. The tubes
are concealed under the seats. The gas
tanks are covered by plates. No part OF
the machinery is visible inside Of the car.
II is only accessible from the outside by
opening the two large doors above men
toned. and number OF smaller doors.
The car, while in motion is noiseless, and
there is no odor from the gas.
The driving gear consists or four shafts.
The motor shaft is driven directly by the
gas motor. and transmits the motion by
means OF cogged wheels on the shaft. on
this shaft there is peculiar friction coup
ling as shown in the cross-seCtion view OF
the machinery.
This friction coupling regulates the
speed of the car. by means of a reversing
lever. connecting a larger or smaller spur
wheel, as may be desired, with the other
parts OF the machinery. BSSh wheel aNies
are driven by chains and >chain wheels,
which run in oil, SO as to use the entire
adhesive weight of the car for the develop
ment OF the tractive power. To diminish
the friction the bolts at the Joints of these
chains are incased in steel. which can
revo!ye, and thus prevent any noise while
the machine is working. During short
stops the machine remains in motion. BY
means of a lever the machine is thrown out
of gear To stop the car, while out of gear
the motor uses very little gas, because the
number OF revolutions Is diminished, and
only after every eight or ten rotations
a new ignition of the gas occurs. which is
sufficient to keep the motor In motion.
One of these levers is connected with the
friction coupling, and serves To dimin-
ish or increase the speed Of the car from
$50 TO 240 rotations per minute; the other
lever is sdirectly connected withthemotorand
controls the movement nf the ear forward
or backward. The levers are easily con-
troIled by the conductor.
An alarm bell. similar to those used on
ordinary horse cars, is attached to the handle
of the brake. The levers and brake handles
are easily removed from one platform to
the other, as may be required when chang
ing the direction of the car.
The wheels of the car Are peculiarly
fastened to their sxIes. One wheel is Sc
cured to the axle. while the other can
slip in its hub in the proportion Of so per
cent of the circumference OF the axle to-
ward the neighboring wheel, until it is
necessarily taken along by the rotation Of
the axle. Thus, both wheels can revolve diff
ferently when the car takes curve, and
the friction or resistance caused by the
curve is greatly diminished.
The speed obtained at the trial trip was
aC the rate OF fourteen kllplNelres, OF dDDut
81 miles. per hour. IL curves were over
come with ease, and without any sway
or Jerking motion. the smallest radius being
fifteen metres, ,49.2 feetE. The speed
was diminished while passing over tue
curves.
The consumption of gas amounted to
about one-third of one cubic metre (11.74
feeO per kilometre, (0.621 $40 mile) one
cubic metre (35.316 feet of gas costing 12
pfennigs t2.S6 ccnts). The average cost
of casper miometre, or 3.2s0feet lOiDches,
would be 0.O4 pfennigs tO.95 cents).
The gas used for the motor is under a
pressure of 6 atmospheres, and the mano-
metre shows at all times the amount Of
gas consumed.
The compressed gas enters at first into
a regulator for gas pressure tPiDtsch sys-
tenn, where the pressure is reduced from
thirty to forty millimetres, 1.1S inches
to 1.57 inches) water pressure. The gas
contained in the three gas tanks, viz:
0.95 cubic metre 1885 feet is sufficient
to run the car II L kilometres 10 90 miles,.
