being provided with an Independent
50-horsepower motor. This machine
was manufactured by Giddings
!, band saws used by the Great South
= ern Lumber Company come mainly
e from the E. C. Atkins Saw Co. OF
4 indianapolis, Ind, although a consid,
: cradle proportion of them are pur-
: chased from the Disston Saw Co. OF
r Philadelphia, Pa, and from the ST.
monds Manufacturing Co. Of Fitch
burg, Mass. The standard used here
: IS IA inches wide, of No. 14-gauge
steel, with q inch tooth space, the
total length of each saw being IA
feet. They are worked down to a
minimum of 10 inches The life of
each saw in the grade of lumber cut
at Bogalusa is four months, the driv-
en- speed being $500 feet per minute.
AS matter of detail, it may be of
interest to note that Atkins silver
solder is used for brazing broken
saws, in conjunction with NokorOde
soldering paste, manufactured by the
M. W. DuntOn Company of Provi-
dence, R. l. The company has an
expert brazer, and working with
these supplies the joints prove sound
and reliable. The brazing iron is
made locally from Swedish iron.
In addition to the band saws, there
are two gang saws, with 80 saws
each, one made by the Diamond Iron
: Works, Minneapolis, Mimi, and the
other by Wiclles Bros, East Saginaw,
: Mich, and also three resaws, made
! by the Filler & Stowell Company, of
! Milwaukee, Wis. The usual system
of conveyors is employed, the sorting
! being done at the end of the mill
When cutting 100000 feet per day
of 20 hours, as at present, five sort
ers are required on each 10-hour
shift. Some of these are white and
some colored. The accuracy of judg-
ment, combined with the necessary
promptness Of decision to prevent
being overwhelmed by the steady
stream Of lumber coming forward,
was one of the most significant things
in connection with the workmen to
be seen at this plant.
At the end of the mill the stream
Of lumber is diverted at right angles
into two opposite courses, one going
to truck leaders for transmission to
the stock yards for open-air drying. |
On the way every piece is sent
through a mechanical dipping ma
chine, where the lumber, carried |
transversely on the conveyor chains,
is depressed by rollers into solu-
ton tank, and then sent on to the |
trucks. There is thus a continuous
stream of lumber being immersed in |
/ nf hn
cOnveyor chains. The object of dip !
ping is to coat the lumber with al
kali that will prevent sap-staining |
and bluing, which ordinarily happens
to lumber stacked in the open for
air-drying. The effect is extraor-
binary. Lumber is stored in the
open for months and remains bril-
liantly yellow and lustrous, apparent
ly even brighten than when fresh
from the saw. Formerly a solution
of plain soda ash carbonate of soda,
Na2CO3) was used, but recently a
better mixture has been adopted,
consisting of As per cent sodium BIZ
carbonate (HNaCO3) and So per
cent sodium carbonate Na2CO3), the
formula being to dissolve one pound
of the mixture, in the proportions
given, in one gallon Of water. The
covering strength per 1000 feet
board measure is five gallons of the
solution. The soda compounds used
are what is known as the 'Zenith
put up by Church & Dwight,
New York.
The dipped lumber is loaded upon
trucks, which are taken to the load
ing terminal Of the monorail system
mentioned, operated by
two men, an engineer and a clutch
man, and the whole car with its load
is taken and deposited on any de-
sired track in the stock yard. There
are now 100000 feet of lumber
on hand in these yards, which is be-
low the average. The total stock of u,
lumber now carried, both in the
open yards and in the stock sheds, !
IS 35,000,000 feet, which is 10000
300 below normal. ,
The second stream OF lumber di- i
verted by the sorters at the end of I
he mill is sent to drying kilns. It {
goes first to a single sorter, who 7
sorts as to length and thickness only, !
each board into it's apprO- T
pirate slot in the edge of cOnveyor, |
| Whaley sorter made by the Filler +
Stowell Company of Milwaukee, :
which takes it to the proper side of f
he conveyor, which delivers it to the /
stacking machine, that loads the +
rucks for carrying it into the kiln. Z
There are three batteries of eight a
,ilns each, making "a in all, each t
lolding Is trucksloads, the truck j,
DAD being about $500 feet. The q
,ilns are steam-heated, with steam at t
10 to 12O pounds. The lumber is Q
lried in 72 hours, bringing it down q
rom a green weight Of 4400 pounds =
o a dry weight Of 34OO pounds. t
from the kilns the dry lumber is U
transported to the stock sheds, which O
ccupy an area of five acres. IN
There is some waste, as well as all d
f the sawdust, going to the boiler f
DOM from the sawmill proper, but b
he larger part Games from the plan
ng mill, consisting Of shavings, dust
nd "hog material from a half-inch
o two inches long. The planning mill
