MuLERs CAR-BRAKE-AS IMPORTANT IsyEsTros.-
On two occasions recently have referred TO the
invention of felow-citzen, Henry Miller, Esq, for
brang cars by the Of steam from the locomotive.
For time past this invention has been in operation
upon the Pontiac train Of cars The apparatus de-
scrbed in previous notice, consists simply of steam
pipe extending from the locomotive 10 cylinder attached
to each of the tram and in which there is piston that
operates upon the brake by means Of an iron rod This
apparatus extremely simple and is under the absolute
control of the engineer. The power be applied 10 the
brakes almost upon the first Indication of
danger. Yesterday short trip was made upon the Pom
tac road for the purpose OF giving the invention prac
going the of twenty miles hour and the train
was brought 20 dead stop in distance Of fifteen rods
without reversing the engine causing the slightest Jar
1t applied while the train was going at the rate
Of thirty miles hour and in distance of thirty rods
and in fefy seconds u time the train again brought
to dead stand This repeated the second time and
without reversing the engine II this had been done the
cars would have been stopped in about twohrds of the
distance and time
But perhaps the best practical test of the great i'm
porance OF the invention was previously afforded. While
on Its outward trip and going at the of twenty miles
an hour several horses suddenly discovered on the
track directly in front Of the engine and by applying the
brake the Tram was almost Immediately stopped By the
old plan II is admitted that would have been impossible
TO have stopped II in time TO avoid running over them
Before the brakemen could have been their posts the
mschlef would have been done. This of the great
benefits that must result from Mlers nyenon The en-
gneer can apply the brakes every wheel in the train be-
isre he could give the alarm to brakemen Another sd
vantage possesses in the great saving Of wheels.
operates upon every wheel equally and with the
power Again in Gaze Of danger the rst impulse Of the
brakeman is self protection, and he never fails jump
from the when there il reasonable probability Of q
collision or other accident that might hazard his fe But
to apply the brake by this invention is but the work Of
instant On the part Of the engineer and them natter

safety by flight the p0r continues TO be eIerted upon
