ing purposes is admitted to the interior ofthe
roll or drum I, and an exhaust pipe 6 through.
The invention relates to 'steam heated rolls of
the type used in paper corrugating machinery, as
which the condensate is withdrawn vby the Siphon
drier rolls, and for similar purposes, wherein it
is necessary to exhaust the condensate from the
mechanism hereinafter described.
'
` '
'
The Siphon mechanism is provided with an
elongated exhaust conduit member 1 whichv for
interior of the roll or drum. This is usually done
by a Siphon pipe which is projected through the
axial hole through the central hub at one end of
the roll7 from which point it is necessary that
the. Siphon pipe project ldown and be accurately
positioned close to the interior wall at the bot
tom of the roll. The necessarily small size of
the axial hole above referred to makes it diffi
purposes of rigidity> and strength preferably ex
tends through the roll I from one hub to the
other, and is provided with supporting portions
at both ends. As shown in Fig. 1 the left'hand
end of the member 1 is secured to the'rotary
steam joint 4 and the right hand end of member
1 projects into and iS supported by a threaded
plug 8 in the hub 3 of the rol1,'the member 1 re
maining Stationary while the roll rotates.
The exhaust conduit member 1 is provided with
cult to _provide a 'Siphon pipe which may be con
veniently inserted through the hole and accu
rately positioned and maintained in proper place
adjacent the interior surface of the roll near its
bottom. This accurate positioning is important
in operation, and also it is necessary that the

inserted through the small central hole which is
available, accurately adjusted and held in proper
operating position, and sufficiently strong and 3 l)
rugged to stay in proper operating condition with
out frequent attention or repairs, under the oper
ating conditions usually encountered.
Further objects and advantages of the inven-v
tion will be in part obvious and in part Speciñ- i
_cally referred to in the description hereinafter
contained which, taken in conjunction with the
accompanying drawing, discloses a preferred
Siphon mechanism constructed yto operate in ac

ever should be considered as merely illustrative
from the standpoint of the invention in its
broader aspects. In the drawing-

in Fig. 2, where it lies alongside and is substan- .
tially parallel to the exhaust conduit member 1,
and another position wherein said Siphon mem
ber I I is directed outwardly away from the mem
ber 1 and has the inner end of its passageway I2
in communication with the port Il).

While the Siphon member is in the ñrst men
tioned position, the exhaust conduit member 1
carrying Such Siphon member maybe inserted
into the roll through the hole 3a above described.
Then the Siphon member is tilted to the second
position wherein its lower or outer end portion
IIa will assume a position closely adjacent the
interior Surface of roll I at the bottom of the
roll, when’ the end portion 1a is engaged with
plug 8 above described. The steam joint 4 will

ner and the Siphon mechanism is ready for op

that as Siphon member H swings into operative
position its inner end Hb overlies the port I9
and thus applies the suction from passageway
9 to 'the condensate located in the bottom portion
of roll l. The construction may be readily
adapted to rolls of various diameters by substi
tuting Siphon members of appropriate length,
each of which is accurately finished So that its
end portion Ha will be properly positioned for
the particular diameter of roll which it is de
signed to serve.
The construction requires no flexible or struc

supported at both ends, better withstands the
vibrations and holds the Siphon member I! ac
