SOMETHING NEW in BARRELS.
q Decided Departure in the Manufacture

of Very Useful Article.
You wouldn't think that anything new
cCuld be written about such q hOmely
subject as a barrel, but a decidedly new
departure is to be chrOnicled The barrel
of commerce is made by splitting the log
into bolts about thirty inches long. The
5Olts are placed in a large vat, subjected
20 an intense steam heat for twelve hours,
and then, while hot, are cut up into slaves.
After five or six months of air drying the
slaves are ready for the listing Tor joint
ing machine This process completed,
the slaves are in proper condition for the
cooper, who trusses them (arranges them
In barrel FORM and cuts the chine and
croze, after which they are ready for heads
and hoops. Shaving, planning and crOZing
machines are used in the manufacture of
common barrels, and in each barrel there
are sixteen slaves. The new barrel is
made of two slaves.
In an establishment where they are
manufactured 1 saw an elm log thirty-one
inches long and twenty-four inches in di-
ameter, resting in q steam vat. A crane,
operated by steam power, grappled the
log and swung it into position in the ma
chine. This wonderful piece of mechan-
ism clamps the log exactly in the center
and Immediately begins a motion of fifty
revolutions to the minute When the log

the machine knife is fed directly on the
outside of the log, cutting off continuous
sheet the proper length and thickness of a
stave. In this way the entire log is util-
lied as stave material except about six
inches of the core or heart, which is prac-
tically worthless. On the opposite side Of
the cutting knife, and revolving upon the
surface Of the log, are two cylinders,
being held thereon by the same mechan-

revolution of these cylinders measures a
half barrel of continuous and solid stave
material. In the surface of these cylin-
ders is a knife, which is forced into the
solid Og, cutting off q sheet, which falls
on to q cOnveyOr in the perfect form of a
half barrel. This half BARREL which has
just dropped from the log. is completely
chined, crozed and equalized. It's eXter-
nal form is superior to any work which
the most expert cooper can execute. 1t is
fundamentally true The Ginning,
crOzing and equalizing have all been done
by the same knife, and the perfected half
barrel is the result of the single mechan-
ical revolution.
The elm log referred to remained in the
machine fifty seconds, at the expiration of
which time it had been converted into
thirty-fOur slaves or material for seven
teen barrels. The slaves are dried, listed
GOinted) and then receive head and hoops
Two hundred and twenty barrels are
made from 1 200 feet of log measure. BY
the old style of manufacture the maxi
mum product is about fifty barrels less.
On the old barrel, with sixteen slaves,
thirty-two istings are required. Here
only four HstingS are made. The saving
in this detail alone is great. AS labor
saving invention it represents an advance
of 60 per cent. on the old method of man
ufacture. Barrels, nail kegs, butter tubs
and pals are turned out at will with this
wonderful machine. The inventor, a
Michigan man, has had the idea germinat-
ing in his brain for over twenty years, but
it was only during the present year that
the mechanism was perfected. Chicago
