The L'Anse sentinel. (L'Anse, L.S., Mich.) 18??-current, 1892-02-06

exhibited Mt their works In Lynn
Mass, the first freight locomotive {

The new locomotive is designed t,

by this means merchandise back ant
forth from the railway station, dis
lance OF a mile and half. The tota
weight OF the locomotive is 5000
pounds, and the speed, when deliver
ing thirty-horse power at the draw
bar, is five miles an hour. This will
pull on n level from six to eight heay.
lily loaded freight cars, weighing. from
200 to 800 tons.
The exhibition was a complete sue
cess in every way. The piece of track
used was curve and IN up grade, 80
that drawing a given load over it was
equivalent to drawing three times
that load on q straight and level
track. Two freight cars weighing
fifty-four and one-half tons were first
attached to the locomotive. They
were drawn easily around the curve
and up the grade, started, stopped
and backed without difficulty. This
experiment was in itself practically a
complete demonstration OF the success
OF the new machine. But severer tests
were applied. Two more cars, bring.
ing the weight up to ninety tons,
and finally two more still, making u
weight OF 1873 tons, were added to the
train. Again the locomotive drew
them back and forth without any
apparently added difficulty whatever.
Some data of the locomotive are
given below: Voltage OF locomotive,
300 volts; horse power at draw bar,
100; speed on level track when devel-
oping above power, five miles per
hour; wheel base, 6 feet 4 inches; di-

Just Like Bird.
The new flying machine, or "avia-
eur" recently brought before the
Academic des Sciences, Paris, by NJ.
Trouve, is highly ingenious,
Ind a new departure in aeronautics,
out is only in it's experimental stage.
nj. Trouve believes that none of our
existing motors-whether of steam,
Electricity, or compressed air-are
capable ofpropeling vehicle through
he air, without the support OF bal
oons or aeroplanes such rs Mr.. Max
m IS now working at. In order to de-
use such a motor, he took up the
principle OF the Bourbon tube, which
8 employed as manometer or
PRESSURE gauge. This tube is
# q horseshoe form, and when
He'd with the gas whose press
ire is to be measured, the points
Il the tube approach to or recede
rom each other according as the press
ire of the gas falls or rises.
NJ. Trouve saw that he could trans

Exploding the mixture with proper
artridges fixed on revolving barrel. |
1t each explosion the pressure of the
as in the tube would fall, and the |
POINTS in the tube approach, while on
efilling the tube with gas between the
EXPLOSIONS the points would recede.
n this way reciprocating motion OF |
he points woald be obtainable as
ong as the supply OF hydrogen and
he exploding cartridges lasted.
To utilize this motion, he fastens All
expanded artificial wing to each point
If the tube: and these wings rise and
all as the points approach or recede,
hus beating the air like bird s wings.
A Warlike Clock.
A novel clock is now being exhibit
d by the tchmakers' Union in
1t is of wood, beautifully
.arved, and stands six feet in height.
The case is a perfect fort in miniature
Ind, instead OF @ bell and striking
the hours are announced by
. bugler, who emerges from door at
,ne side of the fort and blows the call
20 assemble and march.
Almost instantly the doors open on
Ill sides; q regiment OF automatic
six abreast, march out, wheel
20 the left, stop a few seconds to
mark time" and then march
through another part OF the fortress
10 the barracks. These marches and
counter marches occur each hour,
says the Chicago Press.
II they come out to announce the
hour of o'clock, one soldier fires his
tiny gun; at 2 o'clock two soldiers fire
their pieces, increasing with the hour
until the twelve leaders fire their guns,
the rear ranks bowling their heads and
with their bayonets toward
the dial of the clock.
Ice Made BY Natural Gas,
An inventor in Buffalo, N. Y, has
devised process for making ice by
utilizing the intense cold created by
the explosion of natural gas when lib
srated from the high pressure at which
