This invention relates to textile treating apparatus hav
ing an automatic controlling device for regulaing the
temperature on the drying section.
In the textile industry, it is conventional to pass a
plurality of ends of'yarn continuously through a size
box, thereby impregnating the yarn with liquid size or
the like. After impregnation, the excess size is squeezed 15
tinuously variable steam pressures. A leverv 20 is pivoted
to the valve stem extension 21, ‘and in turn is pivoted to
another lever 22 which is pivoted to a bell crank 23 hav
ing a stationary pivot ‘24. The bell crank‘ 23 is operated
by a plunger 25 which reciprocates through a stationary
bearing 26 and which is connected to .friction disc 27.
A spring 30 is provided continuously urging the friction
disc 27 toward the right as seenjin the drawing.
Another friction disc 31 is provided, in angular con:
tact with the friction disc; 27.. The friction disc

The sleeve 32 is splined to an internal’ shaft ,34 which in
turn is driven through a stationary bearing 35 by. a gear
out of the yarn and the yarn is then passed through a

The drawing represents schematically, in side eleva- '
tion, an apparatus embodying features of this invention
and accomplishing the objects heretofore referred to.
Referring speci?cally to the form of the invention se

It will be appreciated that the temperature of steam
is approximately proportional to its pressure, when the
steam is saturated. Therefore, the control system speci?
cally disclosed herein provides a ready and convenient
means for changing the temperature of the peripheral
surfaces of the drying cylinders.
Accordingly, when the yarn is passing at low speed over
the surfaces of the cylinders, the steam pressure is sub
stantially reduced, thereby counteracting the fact that
the yarns ‘are in contact with the drum surface for a
