train OF ten cars las miles in las minutes run
ming time. This was done On a five foot wheel
six-coupled engine.
Returning TO a description of the valve gear.
the valves are operated By a single eccentric for
each cylinder, the eccentric being keyed fast
TO the shaft or axle. This eccentric runs the
engine both ways, and imparts an independent
motion TO the steam and exhaust valves. so that
the engineer has perfect control over the point
of cut of without altering tho travel of the ex-
haust, and can alter the compression without
changing the travel of the steam. In this man
ner the engine makes the rame
card or gives the same distribu-
ton OF steam as a nicely adjusted Ccriiss or
Greene engine would do at 9 given high-piston
speed. This enabled her TO DO her work with
from 20 to SO per cent. less water. ard conse-
quently less steam. Her large crate area en-
ables her to burn her coal So as to give an evap-
GRAFTON from % to SO per cent. higher than
ordinary locomotive boilers doing the same
work, so that the combined action of boiler and
valve gear Is to make a very economical engine,
and one that is capable. it is claimed. OF taking
an extremely heavy train OF from ten to fifteen
cars, ana making sixty miles an hour with ease.
The locomotive has four wheels. swing truck,
under her front end, like an ordinary machine.
her drivers, 68 inches IN diameter, are midway
between the front and rear ends OF the boiler.
Back of the driver is q two pony truck,
42-inch wheel, which 10 eoualiZed with the
drivers, making ten wheels under the engine.
The tender 10 carried on a four wheel truck
forward and q six-wheel truck back, making ten
wheels in all under the tender. The total weight
is over sixty tons. The engineers cab Is over
the hind driver, forward of the double fre-box.
He has a very extended view OF the track on
both sides, and is entirely away from the dirt
and dust of the tender, and his cab rides as
nicely and as clearly as a parlor car. The fire.
man has a cab on the back end of the fre-box
entirely TO himself. They have communication
by q passage over the top Of the fre-box be-
tween the two cabs. the engineer having u call
bell with which TO summon the stoker If he
wishes TO speak with him. The locomotive
wheel base is twenty eight feet, the wheel base
Of engine and tender, forty-eight feet; total
length over ali, about ffty-iv feet. The high
est point of the engineers cab Is thirteen feet
seven inches from the ground. Her freman's
cab. which, like the drivers. IS very roomy, is
built of heavy iron plate. The engine has no
extended front arch or netting or device for
spark-arrester, as they are no: required.
Her inventor is Mr.. George S. Strong, who
was in the city yesterday inspecting the touch
to breaking her il to complete and facile run
freiRhts between Providence and Stonington.
and next week she will be put on to 8 regular
fast passenger train between here and the Con-
~necticut terminus of the New York, Providence
81 Boston railroad. She left the Huxley works,
in Boston, at 3 p. NJ, Wednesday,. and arrived
here at $50 under charge of driver John Mckee,
of the Hinkley works. and fireman j. McGruvy.
Thursday she make the run, with pilot II.
