which bss the property Of rsmaitins elastic and tight

North Star the New World, and several ether steam

roads as packing for ell the ufngboEes. Is is s-o

is made in rolls Of various sizes and is crowded down
into conical stpffng-box, the common stuffng box
beirg made conical for this purpose BY inserting

rods which had acquired an extremely CLASSY polish
while usirg this convenient packing.

MmLER's sTEAM.cAH BRAKE Mr.. Henry Miller
Of Detroit 10 the inventor Of g device for stopping
train of cars at the will Of the engineer, which j, a:
the same time the most coneo: in theory, the most
te1sively esed ano the most uniformly successful OF
any for tits purpose yet developed. The cars are
stOpped 10y friction upon the wheels in the usual man
ner, but the brakes are sppHed by the aid Of steam
from the boiler. Ordinary bandwhecls are provided
usual at TIE ends Of the CARS bat except in of
deIsDgtment or in switching the necessary pressure
uI on the brakes is obtained in all cases-orinary as
well as e1traord may from piston confined in a
Horizontal G. Under under the center of each floor.
Every cor is provided with pipe running lengthwse
end with piece Of saorg flexible hose to connect the
same with that OF the next one. This pipe supplies
.t am TO one end Of the cylinder and thus driver the
piston toward the other end, ghte ming all the brakes
by its connection with the Usual compound levers.
Turn-brckles are provided by which the rods MAJ be
taken up to cOmpen shte for wesr The brakes Of
the usual proportions shod with from the cylinder is
-ix inches in diameter; the stroke or motion allowed
The piston is Ten inches, and the diameter Of the pipe
