Journal bearing in Il machine is one of
| the most recent, and has been found very
satisfactory. This machine consists OF Il
steer piston or short Shaft to be rotated
ana Il oastlron ring or cylinder which acts
as. bearing for the shaft, the whole
| beng supported on rollers mounted on !,
| suitable frame. The shaft weighs fifty
and one-half pounds, is six and one-quar-
! ter inches long AMI six inches in diam
eter. and it's weight constitutes the total
diameter of the cylinder is slightly less
I than 1~2O0O of an inch larger than tha
| shaft. Both cylinder and shaft are
sr0und exactly parallel.

the shaft, also when inserted 1t is ro-
tated with the band by Il handle at the
end. At first the harsh. grating sound
will be heard and it turns with difficulty.
but by increased speed the grating ceases
and the power required to turn the shaft
IS materially, decreased until after Il few
revolutions the shaft will be entirely free
from the cylinder and rotating on il thin
film OF air between them. If making 500
revolutions per minute and the power
was stopped. it would continue to rotate.

the fuel until the latter is wholly iynited.
The tirrdcor is kept closed to prevent the
admission of cold air and causes the
draft to pass up through the fuel This
is found to be Il decided Improvement
over the Old method of blowing through
the hrrdoor with the jet OF flame strik-
ing the trebox Sheets. Less injury is
said to be done to the inner sheets than
is done by Il wood fire for llindliny.
The same apparatus is also used as 4
hloWp.pe in strengthening flames and
heating tires. The heat in this way may
be applied to the needed places without
affecting those adjacent.-\t York
