PROVISIONAL SPECIFICATION.
Improved Pressure Regulating Mechanism for Wringing and
Mangling Machines.
We, HENRY CROFTS LONGSDON of the Firin of W. Summerscales and Sons
Limited of Keighley in the County of York, Laundry Engineers and Machine
Makers, and FRANK WILKINSON of the same place, Manager, do hereby declare the
nature of this invention to be as follows, that is to say :-
In connection with the class of wringing or mangling machines wherein three
rollers are mounted to operate in one and the saine vertical plane, considerable difficulties
and inconvenience has been experienced by all the pressure put upon, and the motion
of these rollers being caused to act in one direction, and to obviate this and produce
mechanism that shall act equally upon the roller below the central one as upon that
above it as well as afford more space for the receding movements of these rollers is
the object of this invention.
In carrying this object into effect we arrange the middle or central roller to rotate
in fixed bearings, while the rollers above and below it are free to advance towards or
recede from it as occasion may require..
The sliding bearings "or dies" in which the upper and lower rollers are mounted,
are coupled together on both sides of the machine by appropriately formed connecting
rods, while springs are mounted on each side of the machine to intervene between the
said "dies" in such a manner that their resilience shall act with an equal degree upon
the upper as upon the lower roller.
These springs may be of the spiral type or by arranging the framework of the
machine to suit the ordinary kind of laminated springs these latter may be
employed.
Regulating screws (one or more on each side of the machine) are used in
connection with the above described mechanism in order that the pressure on the
rollers may be increased or diminished as desired.
The framework of the machine or parts in connection with it, is or are formed to
afford facilities for the mounting and maintaining of the connecting rods and other
parts in their respective positious so that same are made to perform the functions
required of them efficiently.

Improved Pressure Regulating Mechanism for Wringing and
Mangling Machines.
We, HENRY CROFTS LONGSDON of the Firm of W. Summerscales and Sons
Limited of Keighley in the County of York, Laundry Engineers and Machine
Makers, and FRANK WILKINSON of the same place, Manager, do hereby declare
the nature of this invention and in what manner the same is to be performed, to be

page_text: particularly described and ascertained in and by the following statement, that is
to say :-
In connection with the class of wringing or mangling machines wherein three
rollers are mounted to operate in and one and the same vertical plane, considerable
difficulties and inconvenience has been experienced by all the pressure being put upon
these rollers, and also the movements of same being made to travel in one direction,
so that to obviate this and produce mechanism that shall act equally upon the roller
below the central one as it does upon that above it as well as afford more space for the
receding movements of these rollers is the object of this invention.
In order that our said invention may be more readily understood we have hereunto
appended sheets of drawings illustrative thereof to which by figures and letters,
reference is made in the following description in which :-
Figs. 1 and 2 are end and front elevations of a wringing and mangling machine
made in accordance with our invention.
Fig. 3 is a similar view to Fig. 1 but drawn to an enlarged scale, while parts of the
framework which do not form any part of our invention are drawn as cut away.
Figs. 4 and 5 are front and end elevations of a certain part of the machine and
show modifications hereinafter explained.
In carrying our invention into effect we arrange the middle or central roller a
to rotate in hearings & fixed to the framework c, while the rollers d and fabove. and
below it are free to advance towards or recede from it as occasion may require.
The sliding bearings or "dies" 9 and in which the upper and lower rollers d and f
are respectively mounted are coupled together, on both sides of the machine, by
appropriately formed connecting rods k m passing loosely through them to be secured
at their lower extremities to the sliding block p and at their upper extremities to the
screwed block r, while their said upper extremities also pass loosely through the
sliding block a.
Between the dies g and h, and the sliding blocks s and p respectively, are mounted
the springs t and u by which means as the screw w is rotated in the direction to make
it advance through the screwed block r its lower end we will press upon the sliding
blocks thus the tendency of the screw to force the block t in an upward direction
will be equal to the tendency it has to force the block in a downward direction,
hence since all such force or power acting upon the block is transmitted through
the rods km to the block p thence through the spring u to the "die" A and so to the
roller, while that acting upon the block is transmitted directly through the
spring to the die g and thence to the roller d, it must follow that the pressure
exerted by the screw w acts equally upon the rollers d and f, so that one is as
free to be moved to press upon or be separated from contact with the roller a as is
the other.
The springs and u are of the spiral type and although it might be possible to use
the usual laminated springs the additional fittings to enable same to be carried out are
too elaborate and cumbersome to warrant their use.
The regulating screws w (one on each side of the machine) pass loosely through the
guide pieces to act upon the springs t u as above described while to keep the
rods km in position they pass loosely through openings made in the several parts b, g,
hands which thus act as guide pieces for same.
In order to arrange the above described pressure mechanism so that only one
screw w is necessary to operate the two springs tu on both sides of the machine we
mount the cam levers y between the sliding blocks rs as shown by Figs. 4 and 5 so
that the screw in the middle of the machine may transmit motion to both of them as
will be readily understood.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what
we claim is :-
1. In wringing and mangling machines the several sliding blocks, rods, springs and
screws arranged to onerate in combination substantially as herein specified

page_text: 2. In wringing and mangling machines the several parts for transmitting pressure
to the rollers thereof substantially as herein set forth and described.
3. The devices herein described for regulating the pressure on the three rollers of a
machine substantially as set forth.
