staub steam FIGURING rIIn.

Mr. DANIEL L. JUNE, has got his Touring
mill about completed. So far that he will
commence grinding to-day, and in the
course of a few weeks will be ready to do
all the work customers may want. We took
look through his establishment on Tues
day and were highly gratied with it. There
are at the present two run of stones, capable
of grinding IL to Is bushels of wheat per
hour. Everything about the mill has been
built with strict regard to convenience and
utility. Sparing no expense, and custom
ers need not fear of obtaining the best of
-four. Mr.. JUNE intends to manufacture
and keep on hand, for the use of the citi-
zens of Fremont an article he can recon-
mend as No. l.. The mill is situated in the
east end of town and is easy of access.
In connection with this we must speak Of
the Steam engine, which was built for Mr.
JUNE, at the extensive iron works of Messrs
DAVID JUNE and LYMAN GELPIN of our
town. This specimen of the skill of our
townsmen will greatly increase their reputa-
ton, and we think there will not be any ne
cessity of that Boston establishment coming
here to teach Fremont mechanics how to
work.
In most engines yet invented for devel-
oping mechanical effect from steam, there
are great irregularities in their velocity,
which proceed from two sources, one, the
mechanism of the engine itself, the other,
the resistance which the engine has to over
come. From the mechanism of the engine,
we see that the piston does not move with
a uniform volicity through the cylinder
The volicity is greatest at half stroke, and
gradually decreases until it stops altogether,
and returns in the opposite direction. The
crank is the best constructed expedient for
deriving a rotary motion from the reciprocal
ting motion of the piston, but with single
engines it has the defect of not transmit
ing uniformly the pressure and volicity of
the engine. In most of the applications of
the steam engine, this inegularity of yeloci-
ty is great evil, and every cxertion should
be made to overcome it and produce uni
form motion, especially in the manufacture
of flour. This uniformity of motion is fully
obtained by Messrs. JUNE & GELpIN, in the
mill above referred to, by attaching two
engines to the main shaft, which ensures
the most perfect uniformity of notion
Their ingenious plan consists in applying
two engines to one crank. This is effected
by placing the engines at right angles tc
one another, and causing them to work upor
the same axel, by the means of their con
necting-rods. The valves are wrought by
simple and ingeniously contriSeG eccen
trio, by which the steam is alternatively ap
piled to tho two engines. From this form
of construction, it follows, that when tho
piston of one of the cylinders is at hal
stroke, the piston of the other is at ths ter
mination of its stroke, and thus tho irregu
larities of the one engine counteracts that o
the other. Another advantage in this ar
rangcment is, it dispenses with a consider
able amount of shafting and geering, re
quired by the common mode of application
and thus not only saves power but render
the construction of the machine ITSELF mucl
more simple and convenient. 1t will pa
man we'll to visit the new Steam Flour
ing Mill of Mr.. JUNE.
