MATERIAL-ACTUATED RE EnsE FOR cLo'rHEs-wRmeEns.

To all whom it may concern: v

Be it known that I, EDGAR B. STOCKING, a

citizen of the United States, residing at Washington, in the District of Columbia,

have invented certain new. anduseful l mthe Wringer to insure safety to the operator The cross-bar which has a stud and prevent ,over straining and deflection of the roller shafts by excessive feeding. Other objects and advantages of the invention will appear in the following description and the novel features thereof will be particularly pointed out in the claims.

Referring hereof and in which like reference numbers refer to likeparts in all of the figures:

Figure 1' is a rear or delivery side elevation with parts in section of a wringer embodying the invention, and

Taking the above as any ordinary Wringer provided with means "for permitting the 're-, lease of the pressure of the rolls upon each other or upon the material between them, it

now remains to describe the invention to be disclosed herein for releasing said pressure.

Above the delivery board is a roller 14 which is journaled at each formed in'the standards l. A link 16 is the journal of and fall a distance compatible with'a normal feed to the rolls; but if abnormal, then in end in slots 15,v

This adaptation is accomplished by connecting the link 16 at 22,

whereby when the roll 14 is raised beyond the normalworking space or slot 17, in the link 16 with its journals riding in the slots 15 of the standards, the lever forces the Wedges 21 between the the standards, thus releasing said hooks and devices of the v the pressure producing wringer. f The pivot 22 of the connecting" link 16 and the lever 20 is preferably screw spring hooks'll' and I threaded in order that it may be rendered easily removable, sothat the rol1'14 may be ing the releasemanually,

The Wedge levers '20 are extended to the front side of the wringer and are connected by a rod which serves as a means of actuatblow downwardly on said rod by the hand of theoperator. his provision is important in that no mechanism is absolutely infallible and therefore, by this manually operated 'assuredf V v The operation of my improved, material actuated release for clothes Wringers is as- 'follows: 'Wherein adjunct release as in. time of accident, is
