' ‘.12 Claims.’
‘My ‘invention ‘relates primarily ‘to paper ‘mak
ing, and one of the principal objects of my‘in
vention is to provide -a method and apparatus
for making up batches of paper stock comprising
5 various ingredients, controlled by a single’ auto
matic ?ow controlling‘ device; functioning to
vprovide time intervals for the making ;up, in a
primary receptacle, ‘of _~ successive 1batches of the
particular type of paper stock, each batch com
10 posed of relatively proportioned amounts of in
gredients; further causing ‘the ‘delivery of the
resulting batches successively -‘into a receiving
(01. 592-45),‘ 7
?lling of‘the ‘receiving receptacle when emptied
to a predetermined ‘low level; during the contin
uous discharge ‘therefrom, ‘the discharge ‘being
at _:a ‘lesser *rate'than the ‘rate of transfer of
material from the ‘batch make-up receptacle to 1*5
the receiving receptacle.
A'further ‘object of
‘invention is‘to provide
a-control for the discharge from the receiving
receptacle of my apparatus 'into the ‘paper mak
ing system, whereby a ,steady and substantially ‘1'0
‘continuous, constant rate of ?ow ‘from the re
ceiving :receptacle ‘is ‘maintained, and ‘to effect
such result by ‘providing an outlet ‘carried 'by
"from the latter ‘in a continuous, constant i?ow said float ‘by’ which ‘the said ‘outlet is thus at
15 into a stu? chest, =or'other part of arpaper mak
ing system; thecooperative action of said devices ' all times located -a constant depth below ‘the 1-5
level‘of the contents of "the receiving receptacle,
receptacle; and ?nally causing the discharge
being arranged so that the‘rate of delivery from
the batch make-up ‘element of my device into
said vreceiving vreceptacle is greater 1than that
20 of the rate of'the-disc’harge from the ‘latter.
A further object of my inventionfis to (provide
simple efficient means 'for ‘feeding'iinto and} auto
matically rp-roportioningi the desired~ ingredients
in the primary‘receptacle of fmygapparatusi and
‘2,5 to (proportion relatively thegdi?erent'§types=of
pulp -in such primary receptacle.
A vfurther object-of my invention is to provide
an apparatus for the purpose mentioned iadapted
to ‘be combined with'the usual Ibeate'r tub of the
30 paper mill ‘so vthat a ‘part of the pulplcan be
automatically supplied from said 'lbeater tub.
-A further "object of my invention ‘is ‘to provide
automatic means for delivering ~coloring'im'atter,
size, clay and other-desired ingredients -'in pre
35 determined quantities automatically ‘into each
batch of paper stock produced.
A further object of "my invention ~isflto'cause

thus-causing said ?ow to hey-discharged from the
‘receiving receptacle at constant pressure.
' A Ffurthei"object'of‘myfinvention is’to provide
means whereby ‘the volume discharged from said
cutlet-of the “receiving receptacle may ‘be de?
nitely varied by a gate controlling‘ said ‘outlet.
