page_text: We, JOSEPH BOOTH SUMMERSCALES, of the Firm of W. & S. Summerscales'
Sons, of Parkside Works, Keighley, in the County of York, Machine Makers,
and ALFRED JOHN SWALLOW, of 23, Bright Street, Salford, in the County of
Lancaster, Engineer, do hereby declare the nature of this invention to be as
follows, that is to say:-
It relates to improvements in wringing and mangling machines, and
consists in constructing certain of the parts forming such machines,
in such a manner that their upper rollers are automatically raised from contact
with their lower ones whenever the pressure exerted on said rollers by the
laminated springs employed in connection therewith, is removed.
In carrying our invention into effect, we so construct the laminated spring
and the bar for transmitting its pressure to the "dies" of the upper roller that
said spring may freely move over the surface of said pressure bar, during the time
that it is being tightened by means of its operating screw (a plain part which
passes through and thus carries same with it in each direction) and yet raise said
bar when moved in the opposite direction. This may be effected by the ends of
the spring taking beneath suitably formed projections upon the upper side of the
pressure bar, or by pins or bolts fixed to said bar passing through slots formed in
said ends of the springs, or by other suitable means.
The dies of the upper roller entirely encircle its shaft, and are also secured to
the pressure bar above referred to, hence it will be seen that the vertical move-
ments of the spring's operating screw will be transmitted in both directions to the
machine's top roller, thus enabling the rollers to be separated when the machine
is out of use for purposes well known.
As an alternative arrangement, we may dispense with the above described
pressure bar and construct the laminated spring so that its ends take beneath
projections formed on the upper ends of the top roller's dies.

Improvements in Wringing and Mangling Machines.
We, JOSEPH BOOTH SUMMERSCALES, of the Firm of W. & S. Summerscales'
Sons, of Parkside Works, Keighley, in the County of York, Machine Makers,
and ALFRED JOHN SWALLOW, of 23, Bright Street, Salford, in the County of
Lancaster, Engineer, 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, that is to say:-
It relates to improvements in wringing and mangling machines, and
consists in constructing certain of the parts forming such machines,
in such a manner that their upper rollers are automatically raised from contact
with their lower ones whenever the pressure exerted on said rollers by the
laminated springs employed in connection therewith, is removed.
In order that our said invention may be readily understood, we have hereunto
appended sheets of drawings illustrative thereof, in which :-
Figs. 1 and 2 are front and sectional end views respectively of a portion of
a wringing or mangling machine constructed in accordance with our invention.
Fig. 3 is a similar view to Fig. 1 but illustrates a modification of our inven-
tion.
Figs. 4 and 5 are sectional elevation and sectional plan respectively of a further
modification of our said invention.
Figs. 6 and 7 are front and side views respectively, drawn to an enlarged scale,
showing the construction of "die" used in connection with the upper roller of
said wringing or mangling machine.
Fig. 8 is a sectional end view, also drawn to an enlarged scale, of the pressure
bar showing the projection mounted thereon, as hereinafter described.
In carrying our invention into effect we mount the pressure spring a upon
the plain part of the operating screw so that said spring may be operated by
said screw in each direction, the outer ends a¹ of said spring a taking and moving
freely beneath projections c¹ formed integrally with or mounted on the pressure
bar c.
The outer ends c³ of the pressure bar c take beneath projections & formed
on the dies d of the upper roller e (or said outer ends may be fixed to the dies d
in any suitable manner), and said dies are also formed to entirely encircle the
shaft of said upper roller e.
It will therefore be seen that on the screw 6 being rotated in the direction
required to transmit pressure to the upper roller e-the ends a' of the spring a are
free to slide on the bar à beneath the projections c¹, hence its (the spring a)
functions will be performed efficiently and the pressure transmitted as desired,
however on said screw 6 being rotated in the opposite direction, its vertical move-
ment will be transmitted to the pressure bar c, dies d and upper roller e, thus
causing this latter to be raised as desired, for purposes well known.

Instead of forming the projections on the bar e for the spring a to take
beneath we may make use of a screw or bolt 7 (see Figs. 4 and 5) passing through
a slot a in the spring a and being fixed to the bar c, by which means said spring a
may perform its functions as herein before described."
As an alternative arrangement, we may dispense with the pressure bar and
construct the spring a as shown by Fig. 3, so that its ends a may take beneath the
projections of the dies d. or be otherwise mounted to said dies d as to transmit
the vertical movements of the screw b to same in either direction.

page_text: 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 ;-
In wringing and mangling machines, means for enabling the top roller to be
raised from the lower one, the same being constructed and arranged to operate
substantially as herein specified.
