JOSEPH WILDING, of Poulton-le-Fylde, in the County of Lancaster.
MENTS IN THE CONSTRUCTION OF WRINGING AND MANGLING MACHINES."
This Invention relates to that class of wringing and mangling machines which
are made with three rollers placed either two above one or one above two.
The principal defect in wringing and mangling machines of this class as usually
constructed has hitherto been that if a greater thickness of material were to pass
between (say) the first and second rollers than was passing at the same time
between the second and third rollers then the pressure between the last two would
be altogether taken off, and the benefit of the third roller would be entirely lost, or
at any rate greatly diminished, as the pressure would be unequal.
The object of my Invention is to remedy this defect by so mounting the rollers
that the pressure on the two rollers shall be always equal, although the thickness
of material passing through may be different, and this I effect by mounting their
axes in one end of a link or short lever, the other end of which works in a vertical__
slot, so that the rollers can accommodate themselves to the varying thicknesses of
the material passing through, and at the same time keep the pressure equal on
both rollers.
When the three rollers are mounted one above two then I mount the two lower
ones on fixed bearings placed parallel to each other in a horizontal line.
The third roller rests between and upon these two, and is carried at the upper
end of a short link, the lower end of which slides in a vertical slot.
The pressure or weight may be applied either to the axis or to the lower end of
the link (the latter by preference), and the result is that the top roller is capable
of rocking slightly sideways, so that it can accommodate itself to any inequality of
the material without taking any of its weight off either of the rollers.
Or (if preferred) the two bottom rollers may be mounted at each end on a
rocking bearing, whilst the top roller has only a vertical motion in the slot.
When the rollers are mounted two above one the lower one has a fixed bearing,
nd the two upper ones are carried in rocking bearings provided with a central
tud, which moves vertically in the slot.
In this case the weight or spring is applied to the central stud of the bearing
which works in the vertical slot.

"IMPROVE-
JOSEPH WILDING, of Poulton-le-Fylde, in the County of Lancaster.
MENTS IN THE CONSTRUCTION OF WRINGING AND MANGLING MACHINES."
This Invention relates principally to that class of wringing and mangling
machines which are made with three rollers placed either two above one or one
above two, but it may also be used where more than three rollers are employed.
The principal defect in wringing and mangling machines of this class as usually
constructed has hitherto been that if a greater thickness of material were to pass
between (say) the first and second rollers than was passing at the same time
between the second and third rollers then the pressure between the last two would
be altogether or partially taken off, and the benefit of the third roller would be
entirely lost, or at any rate greatly diminished, as the pressure would be unequal.
The object of my Invention is to remedy this defect by so mounting the rollers
that the pressure on the two rollers shall be always equal, although the thickness
of material passing through may be different, and this I effect by mounting the
axes of the two upper rollers at either end of a link or short lever, the pivot or
central bearing of which works in a vertical slot, so that the rollers can accom-
modate themselves to the varying thicknesses of the material passing through,
and at the same time keep the pressure equal on both sides.
Such being the nature and object of my said Invention, I will now proceed to
describe in detail the manner in which the same is to be or may be performed or
carried into practical effect; and in order that the same may be clearly understood
I have annexed hereunto a Sheet of Drawings illustrative thereof, and have marked
the same with Figures and letters of reference corresponding with those in the
following explanation thereof:-
When the rollers are mounted two above one, as shewn at Fig. 1 in the annexed
Drawing, the lower one a, has a fixed bearing, and the upper ones b, b¹, are
carried in rocking bearings c, c¹, at either end of a lever provided with a central
stud d, which moves vertically on a block e, e, sliding in the slot f in the
framing g.
In this case the weight or spring is applied to the central stud d of the bearing
which works in the vertical slot.
When the three rollers are mounted one above two, see Fig. 2, then I mount the
two lower ones a, a¹, on fixed bearings placed parallel to each other in a horizontal
line.
The third roller b rests between and upon these two, and is carried at the upper
end c of a short link, the lower end d of which is carried by a block e, which slides
in the vertical slot f in the framing of the machine g.
The pressure or weight may be applied either to the axis or to the lower end d
of the link (the latter by preference), as shewn in the Drawing, and the result is
that the top roller b is capable of rocking slightly sideways, so that it can accom-
modate itself to any inequality of the material without taking any of its weight
off either of the rollers.
Or (if preferred) the two bottom rollers a, a¹, may be mounted at each end on a
rocking bearing c (see Fig. 3), whilst the top roller b has only a vertical motion in
the slot c.
Having now described the nature and object of my said Invention, together
with the manner in which the same is to be or may be performed or carried into
practical effect, I wish it to be understood that I claim as my Invention, the

page_text: arrangement of mounting the rollers in wringing and mangling machines, as herein-
before described and illustrated by the Drawings annexed, or any slight modification
thereof operating in substantially the same manner.
In witness whereof, I, the said Joseph Wilding, have hereunto set my hand
and seal, this Ninth day of September, in the year of our Lord One thousand
eight hundred and eighty.
