The wringer as shown comprises a support 10

Figure ‘.3, the cam ['9 will be turned to release
35 the spring.’ An operator whose ?ngers were
caught in the rolls by the natural movement of
attempting to pull away from the rolls would
exert pressure on the upper part of the guard
plate to rock it in a direction to release the
40 spring latch. Therefore, even if an ' operator
should be caught in the rolls there is very little
possibility that he would be injured since his ?rst
natural movement would release the pressure on
the rolls.

the guard plate is preferably corrugated as shown
to reduce slipping of the material thereon.
Material passing through the rolls is received
into the rolls, and a connection between the guard
plate and the latch to release the latch upon a
predetermined movement of the guard plate.
2. A wringer comprising a frame, a pair of rolls
rotatably mounted on the frame, means including
on a drainboard 2‘9 terminating at one edge 30
closely adjacent the roll 15 and extending down
and out away from the rolls. If desired, the
edge 30 may be provided with a ?exible strip of
rubber or the like to seat against the roll I 6. At
its upper portion adjacent the rolls the guard
plate is perforated as shown at 3! so that any
water passing through the rolls with the ma
terial will be immediately drained away from the
material and will not be re-absorbed thereby.
Water ?owing over the rolls and through the
perforations 3| in the drainboard is received by
a drain plate 32 connected to the drainboard
just below the lowermost series of perforations.
The drain plate extends away from the rolls in
the opposite direction from the drainboard to
conduct water squeezed from the material away
from the material immediately.
Any water entering the hollow feed plate 21 is
prevented from ?owing on to the drainboard by
a seal 33 sealing the lower edge of the feed plate
against the roll M. The bottom portion of the
feed plate is tapered downwardly away from the

pivoted to the frame and including a portion ex

latch upon a predetermined movement of the
guard plate about its pivot.
