Accrington in the county of Lancaster, Machine Makers do hereby declare the
nature of our said invention for "IMPROVEMENTS IN MACHINES FOR WRINGING AND
MANGLING FABRICS to be as follows:-
=
""
This invention relates to that class of machine for wringing and mangling
fabrics where the fabrics are caused to pass between a pair of rollers in which the
rollers are pressed or held together during the operation by means of spiral springs,
and its object is to provide a simple and easy method whereby the pressure may be
quickly applied to or removed from the rollers, and also for maintaining the rollers
apart when desired, thus relieving them from all pressure.
The framing may be made of cast iron or of hollow tubular wrought iron, the
latter by preference. The bottom roller is fitted in position on a fixed bearing and
upper roller fitted with a movable or sliding bearing, against the top of which
the spring abuts. This bearing may be bored out for its full length, but it is
preferred to make it only a half bearing for the greater part of its length, placing
at one end a cap sufficiently strong to bear the weight and tension of the roller
when being raised. A movable slide is placed above the bearing of the upper
roller, this slide being free to move up and down for a limited distance between the
uprights of the framing which carry the journals or bearings of the rollers. This
movable slide is connected to the journal of the upper roller by means of a rod or
bolt, or rods or bolts, their distance apart being regulated by a screw on one or both
ends of such rods or bolts. Between the slide and the journal the spiral spring is
placed and the two adjusted to the required distance apart to give the necessary
compression to the spring. When thus adjusted the journal spring rod or rods and
slide all move up or down together without altering the compression of the spring,
so that by raising the slide the two rollers may be separated and maintained apart
being at the same time relieved from all pressure, or by lowering it the pressure of
the springs may be easily and rapidly brought to bear. To effect this object the

page_text: slide is so fixed as to be raised or lowered by means of a screw. This may be done
by pivoting or otherwise jointing a screw to the slide, so that it may be free to
revolve, and passing same through a fixed or stationary cap carried by the uprights
of the framing, or the uprights themselves may be chased with a screw thread and
the slide raised or lowered by nuts working on the screw.
In order that the rollers
may be easily and quickly raised or lowered, we prefer to use a screw of coarse
pitch. The stay rod or rods between the journal of the upper roller and the slide
may run inside the spring or be placed outside of it as found most convenient.

Improvements in Machines for Wringing and Mangling Fabrics.
We, JAMES KENYON, JONATHAN BARNES and RICHARD WALTON KENYON, all of
Accrington in the County of Lancaster, Machine Makers, 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 that class of machine for wringing and mangling
fabrics, where the fabrics are caused to pass between a pair of rollers in which the
rollers are pressed or held together during the operation by means of spiral springs,
and its object is to provide a simple and easy method whereby the pressure may be
quickly applied to or removed from the rollers, and also for maintaining the rollers
apart when desired, thus relieving them from all pressure.
It will be best described by aid of the accompanying drawing in which :-
Figure 1 is an end elevation of the machine.
Figure 2 a plan view of bearing for top roller.
A is the framing of the machine shown as made of hollow, tubular, wrought
iron, though it may be made cast iron if preferred. B is the bottom roller fitted in
position on a fixed bearing C. D is a small clip or catch passed over the end of
the spindle b of the roller to prevent its being lifted out of position when the top
roller is raised. E is the top roller fitted in journals or bearings F, which are free
to slide up and down between the uprights a of the frame. The bearing F may be
bored or turned out for its entire length, or be fitted with a cap equal in length
with itself, but as the pressure almost all comes on the bearing above the spindle,
we prefer to put but a short or small cap G sufficiently strong to bear the weight
and tension of the roller when being raised. A little play is left between the
bearing and the cap to prevent any strain coming on the bearing through raising
one end of the roller before or higher than the other. H is a slide fitted between
the uprights a of the framing; above the bearing of the top roller E it is free
to move up and down for a limited distance. The slide H is connected to the
journal of the upper roller by means of bolts h though a single rod or bolt may be
employed, their distance apart being regulated by a screw on the end of the bolt.
Between the slide H and the journal F, the spiral spring I is placed and the two
adjusted by means of the bolts to the required distance apart to give the necessary
compression to the spring. When thus adjusted the journal F, the spring I, the
bolts and the slide H, all move up or down together without altering the com-
pression of the spring I. By raising the slide the two rollers are separated and
maintained apart, and at the same time relieved from all pressure. By lowering
the slide the two rollers are brought together and anything then passed between
them receives the full pressure of the spring owing to its compression between the
journal F and the slide H, at which it is held by the bolts h. J is a cap or stay
fitting across the top of the uprights a and secured thereto by means of nuts j
screwed onto pins fixed in the tops of the uprights. K is a screw passing through
the cap J and pivoted at its lower end to the slide H. The shoulder k presses on
top of the slide to force it downward, or to resist the upward pressure from the
rollers when in operation, the end L of the screw passes through the slide and is

page_text: secured beneath by a pin 7 so that by the raising of the screw the slide H is raised
and with it the spring I, the journal F and the roller E. The screw K is provided
with a thread of coarse pitch, so that a very few turns serve to raise the roller.
Although a single threaded screw is shown in the drawings, we prefer to use a
double threaded screw.
It is not intended to use the screw K. for the purpose of regulating the pressure
on the rollers more than is done by the distance the rollers are set apart, and for
this reason a small handle only is shown to the screw; extra pressure can however
be obtained by further compressing the spring by means of the screw, after the two
rollers have been brought to touch.
It is evident that the stay rod or rods between the journal of the upper roller
and the slide may run inside the spring instead of being placed outside of it if
found more convenient.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we wish it to be
understood that we do not herein claim broadly the regulating or holding in
compression of a spiral spring by means of a bolt or bolts, or of relieving the
pressure on the axles of the rollers without removing the compression of the spring,
as one method of doing this is clearly shown described and claimed in the
specification of our Letters Patent No 3253 of 1883, but that what we claim is
1st. In a machine for wringing and mangling fabrics the combination with the
bearing of the top roller of a inovable or sliding piece betwccn which a spiral
spring is compressed by means of rod or bolts having a screw pivoted or attached
thereto, by which the whole is raised or lowered the screw being sustained by a
fixed cap or support, substantially as and for the purposes described.
2nd. The combined arrangement substantially as described and shown for
removing the pressure from the rollers of wringing and mangling machines without
removing the compression of the spring.
