SODA-TANK 'FOR DIPPING LUMBEE.Specification of Letters Patent.
Patented Dec. 12,1911.
Application iled September 20, 1909. Serial No. 518,561.
To all whom it may concern:
Be it known that we, WALmER CHARLES
TROUT and WILLIAM HENRY TROUT, of Luf-
kin, Texas, and Milwaukee, Wisconsin, re-
5 spectively, have invented a Soda-Tank for
Dipping Lumber, of which the following is
a specification.
Yellow pine lumber in its natural state is
subject to what is known as "blue stain"
10 under certain conditions, and to prevent
this it is customary to . immerse the green
lumber in a solution of bicarbonate of soda.
The means for doing this, as heretofore car-
ried out, have comprised an elongated tank,
15 into which the lumber is dipped and floated
toward inclined chains which carry the
lumber out of the tank. Such an apparatus,
however, has the advantage that the solu-
tion becomes splashed over the operatives,
20 platform, and surrounding objects, and re-
quires one or more men to keep the lumber
from floating crosswise and holding it in
proper position to be taken up by the chains.
The object of our invention is to provide
25 an improved apparatus which will not
simply float the lumber, but thoroughly im-
merse it, dispense with all manual assistance
whatever, and keep the lumber. in perfect
alinement at all times.
30 Furthermore we ain to produce an appa-
ratus which will take all sizes of lumber,
and which will not spill or splash the solu-
tion.
To these ends our invention comprises, in
35 general, a tank having conveying chains and
guides positioned above the lumber and act-
ing to depress the lumber into the solution
and hold it there until it passes out at the
other side of the tank. We also provide
40 means for removing superfluous liquid which
would otherwise be carried out with the
lumber by capilarity and dropped upon the
conveying apparatus and floor beyond the
limits of the tank.
45 Our invention further comprises the par-
ticular constructions and combinations which
will be hereinafter more particularly de-
scribed and set forth in our claims.
In the drawings accompanying this speci-
50 fication, Figure 1 is a plan view of part of
a tank constructed according to our inven-
tion; Fig. 2 is a transverse section there-
through taken on the plane 2; Fig. 3 is a
plan view of the end-portion of a more im-proved form of tank; and Fig. 4 is a trans- 55
verse section therethrough.
In these drawings the same part is desig-
nated by the same reference 'letters or nu-
merals in each figure.
. Referring first to the simple form shown 60
in Sheet 1 of the drawings, upon a suitable'
framework of longitudinal and transverse
beams A, B is mounted a tank C, preferably
of sheet Metal, the two sides preferably dip-
ping toward a vertex c' to which a filling- 65
space and drain-pipe system D is attached, ar-
ranged in any suitable manner. The edges
of the tank are provided with upright or
inturned flanges c2 to prevent spilling of the
liquid. Along the sides at suitable inter- 70
vals within the flanges 02, are mounted a
series of pedestals E, F which carry bear-
ing-boxes e' f' in which turn respectively a
plurality of short shafts G and a single
driving-shaft H. On each of 'the shafts G 75
is mounted a sprocket-wheel g', and on the
shaft H are mounted a correspondingly dis-
posed set of sprocket-wheels h'; and carry-
ing-chains I are mounted to turn on these
sprockets, said chains being sufficiently slack 80
to allow both. laps to dip into the solution in
the tank, as shown.
Longitudinally across the center of the
tank are mounted a pair of beams j', which
support curved lumber-guides J, disposed 85
preferably one over each chain and dipping
into the solution in the tank. The guides J
are preferably made of flexible steel bands.
The links of. the chains I are provided with
teeth or similar projections i , which seize 90
upon the lumber K as it is dropped upon the
chains and propel it forward, carrying it
under the guides J and therefore immerse
it in and carry it through the solution in
the tank and raise it at the other side out 95
of the solution. Before leaving the tank
the superfluous liquid is removed by a plu-
rality of wipers M which are' in the form
of palmetto brushes m' pivotally mounted
on shafts m2 carried by the pedestals' F and 100
the lower end of which is weighted so as to
hold the brushes pressed against the planks
as they pass along over it.
The apparatus will ordinarily be arranged
in connection with conveying belts N, which io
deliver -the lumber over guides n' to the
chains I on the infeed side of the tank, and
in connection with delivery belts 0 upon1,011,280.
