and similar Machines.
We, JOHN HENRY KING and THOMAS BRINKLEY KING, both of The Blue House
Laundry, Sutherland Square, Walworth, in the County of Surrey, Laundrymen,
do hereby declare the nature of this invention to be as follows:-
This invention relates to wringing, mangling, calendering and other similar
machines having two or more rollers which are brought into rolling contact by
pressure, and it consists of the hereinafter described devices for preventing
accidents to the operators of such machines.
According to one part of our invention the pressure screw (or screws if more
than one is used) instead of being threaded into the bridge or other part of the
frame of the machine is threaded into a bush which is itself threaded into the
bridge or equivalent part of the frame of the machine by a coarse interrupted
thread, the said bush being fitted to an arm or lever whereby it can readily be
rotated through the necessary are to disengage the interrupted threads.
By this device the pressure can be instantaneously taken off the roller or rollers.
To prevent the spring (or springs if more than one is used) flying out when the
pressure is suddenly taken off the said spring is either confined by suitable guides
carried by the bridge or other part of the frame of the machine or it is loosely
connected to the operating screw.
Our invention also comprises a safety roller mounted immediately in front of
the feeding side of the rollers. The axle of this roller is mounted in slotted
guides so that it is free to move to and from the rollers.
Our invention also comprises a striking gear for throwing the driving belt to
and from the fast pulley, and it consists essentially of one or more bars-carrying
the striking arms which are mounted in suitable guides carried by the framic of
the machine so that they have a transverse movement therein. The said bars are
operated by a foot lever through a bell crank and suitable connecting gear, the
arrangement being such that the depression of the foot lever shifts the belt from
the loose to the fast pulley and when the foot lever is released a spring acting on
the bars carrying the striking arms operates to shift the belt from the fast to the
loose pulley.

and similar Machines.
We, JOHN HENRY KING and THOMAS BRINKLEY KING, both of The Blue House
Laundry, Sutherland Square, Walworth, in the County of Surrey, Laundrymen,
do hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:.
This invention relates to wringing, mangling, calendering and other similar
machines having two or more rollers which are brought into rolling contact by
pressure, and it consists of the hereinafter described devices for preventing
accidents to the operators of such machines.
We will now particularly describe our invention making reference to the
accompanying sheet of drawings in which;
Figure 1 is a view in front elevation of a wringing machine fitted with our
improved devices.
Figures 2 and 3 are views in side elevation and plan respectively thereof, and
Figures 4 and 5 are enlarged detail views, partly in section.
Throughout the views similar parts are marked with like letters of reference.
According to one part of our invention, the pressure screw A instead of being
threaded into the bridge X' of the frame X of the machine is threaded into a
bush B which is itself threaded into the bridge X' by a coarse interrupted thread b
as shown, see more particularly Figures 4 and 5, the said bush B is fitted or pro-
vided with an arm or lever C whereby it can readily be turned or rotated through
the necessary arc to disengage the interrupted threads 6 in the present case a
quarter turn sufficing.
By this device the pressure can be instantaneously taken off the rollers Y. To
prevent the spring Z flying out when the pressure is suddenly taken off, the said
spring is either confined by suitable guides carried by the bridge X' or other part
of the frame X or it is loosely connected to the pressure screw A as shown.
It will be understood that this device with slight modifications or in some cases
by duplicating the parts, can be adapted to any type of machine using a spring
or springs for obtaining the necessary pressure.
Another part of the present invention comprises a safety roller D mounted
immediately in front of the feeding side of the roller Y. The axle d of this
roller D is mounted in slotted guides a fixed or formed on the frame ✗ so that
the roller D is free to move to and from the rollers Y to prevent the clothes or
articles jamming irrespective of their thickness.
The present invention also comprises a striking gear for throwing the driving
belt to and from the fast or driving pulley F, and it consists essentially of one or
more bars H-carrying the striking arms I-which are mounted in suitable
guides h carried by the frame X so that they have a transverse movement therein.
The said bars H are operated by a foot lever J through a bell crank lever K and
connecting gear k, the arrangement being such that the depression of the foot
lever J shifts the belt from the loose pulley E to the fast pulley F, and when the
foot lever J is released a spring G operates to shift the belt from the fast pulley F
to the loose pulley E.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is: -
1 T

page_text: more rollers brought into rolling contact with each other by pressure, threading
the pressure screw or screws into a bush or bushes which is or are threaded into
the bridge or other part of the frame of the machine by a coarse interrupted
thread, the said bush or bushes being provided with means to disengage the
interrupted threads, as and for the purpose set forth.
(2). In wringing, mangling, calendering and similar machines having two or
more rollers brought into rolling contact with each other by pressure, the use
of one or more safety rollers mounted immediately in front of the feeding side
of the rollers in such a manner as to be free to move to and from the said rollers,
as and for the purpose set forth.
(3). In wringing, mangling, calendering and similar machines, the use of a
striking gear for throwing the driving belt to and from the fast pulley specifically
constructed, arranged and adapted to operate as herein before described and shown.
(4). A wringing or mangling machine constructed and arranged, substantially
as herein before described and shown.
