Be it known that I. CHARLES L. Alumn
SEN. a ‘citizen of the United States. residing
at East Chicago, in. the county of Lake and
State of Indiana, have invented certain new
and useful Improvements in Circulation
Control Baflles for Water~Tube Boilers; and
I dodeclare. the following to be a full, clear,
and exact description of the ‘invention, such

as will enable others skilled in the art to
which it appertains to make and. use the
same.

My invention has for its object to pro
vide a ba?le for controlling the circulation
surging of the water in the boiler and thus
diminishes the liability of the latter to
“prime.”

In attaining the object thus set forth I

place ba?ies or retarders 5 in the upper tubes
as shown in Fig. 1, said retarders being
preferably constructed of metal disks hav
ing their upper edges removed at 6 to per
mit the escape of steam and a limited circu
lation of water, said disks, however, pre
venting rapid circulation through the upper
tubes and thus forcing such circulation
through the others. Tworigid arms 7 ex
tend at right angles from one side of each .70
of water through the tubes ofwater tube disk 5 and are by preference cast as integral
boilers so as to) force rapid __ circulation parts thereof, the free ends of said arms
through the lower tubes to prevent overheat being joined by a transverse bar 8 which
