provide a safety pressure release operable upon
pivotal movement of the wringer by pressure ap
plied 0n any part of the wringer.
I am aware
that pivotal release mechanisms have been made
involving pivotal movement of the wringer in
relation to the gear head or such similar ar
rangement, but such devices involve separating
the gear head from the wringer and supporting
the wringeron pivotal links or the like, which
introduces complications in structure which I
desire to avoid.
Another object of my invention is to provide
means to pivotally mount a practical, unitary
gear head and wringer mechanism by means l20
which will provide a release of roll pressure upon
ñxed position by the taper plunger 23, which is
held in the mating notch- 24-of the pivot plate
2| by the spring 25>aroun`d the‘plunger rod 26.
The plunger rod 26 is slidably mounted in bear
ings 21 and 28. By this _structure it will be un
derstood that pressure applied on the frames I0
and II will tend to pivot the frame III around the
pivot pin 22 and by the tapered notch 24 force
the plunger 23 outwardly" against the spring 25,
whereupon the rod 26 willbe moved outwardly,
pushing the reset lever I4 with it to release the
toggle I 5 and with it the top 'frame I I.
Excess movement of the frame'IIl is prevented
by stops 29 and 30 on the pivot plate 2 I," as clear'
ly shown in Fig. 2. It will be appreciated that

As is well understood in the art, the lower frame
must be indexed pivotally around the washing
machine to provide facilities to wring from out of
the washing» machine or out of associated rinse
tubs. Such indexing is provided in my device
by an indexing mechanism mounted on a bracket
46 attachedV to the _pivot plate 2 i. A release latch
48 is pivotallyf attached to the bracket by the pin
41 and'c'ont'a‘cts‘ an indexing pin '4'9 urged ‘up
wardly by the spring 50 as illustrated. The pin
49 is adapted to engage selectively in notches "5i

release actuating mechanism including a detent
adapted to releasably secure the frame in prede
termined position With respect to the plate.

frame including a plurality of rolls rotatively
mounted in said frame, a spring acting to hold
the rolls in coacting relation, and a cover ex

spring, a drive shaft, a reversing gear :mechanism
