pivot 55 has bearings in lugs 64 struck outwardly
from the‘upper end of the post. The marginal

sustaining hook movable. from its pressure sus
wringer rolls in the frame, and pressure means - 1
taining position, and safety release means for
moving the hook from its pressure sustaining
for the rolls made active by movement of the
top frame toward the lower frame, the combina
tion of mechanism capable of moving the top
frame comprising a lever link extending from one
end of the top frame and mounted for pivotal
movement thereon, said lever link having por
tions included in an unstable toggle mechanism
adapted by movement of said lever link to bring
about movement of the top frame to render said
pressure means active to press the rolls‘together
and means for releasably securing said toggle
mechanism with said pressure means active.
46. In a wringer release mechanism for a
wringer having spaced side frame members and
between which the wringer rolls may extend,
means for imposing wringing pressure upon the
wringer rolls, and means for effecting a quick
release of the pressure exerted by said pressure
means, the combination of means for operating
said pressure releasing means comprising, a bar
extending longitudinally of the wringer between
said side frame members, a pivot connection be
tween one end of said bar and one of said side
opposite sides of the roll axes for pressing the
rolls together, pressure sustaining means con
position.
50. In a clothes wringer, separable roll pressure
applying members, means for maintaining said
members in pressure applying relation including
unstable toggle links pivoted respectively to the
pressure applying members and each other and
forming in pressure maintaining position an
acute angle at the common pivot, a latch for
maintaining the toggle links in pressure main
taining position, and safety release means for
moving the latch from the pressure maintaining
position.
51. In a clothes wringer, separable roll pressure
applying members, means for'maintaining said
members in pressure applying relation including
unstable toggle links pivoted respectively to the
pressure applying members and each other and
forming in . pressure maintaining position an
acute angle at the common pivot, a latch on one
of said members for holding the toggle links in ‘
the pressure maintaining position, and means
for moving the latch from its pressure maintain
ing position.
frame members, means providing a sliding con
nection between the other end of said bar and 70
