Improvements in Wringing and Mangling Machines.
We, JONATHAN BARNES, RICHARD WALTON KENYON and WILLIAM HENRY KENYON
of the firm of Entwisle and Kenyon of Ewbank Works, Accrington, in the County of
Lancaster, Machinists, and JAMES LIGHTFOOT SHORROCK of Hollins Lane, Accrington
aforesaid, Mechanic do hereby declare the nature of this invention to be as follows:-
This invention relates to mangling or wringing machines for domestic or other
purposes with three rollers in which the bearings of one of the rollers, preferably the
central roller are fixed or stationary and is designed to provide for the moving of
either of the other rollers into contact with the central one or fixed one while
maintaining them in such a position that one only will be in contact therewith at one
and the same time.
It consists essentially in bolting connecting or otherwise adjusting the bearings
of the top and bottom rollers at a fixed distance apart and in mechanism for raising
and lowering them simultaneously and for applying the desired pressure to the two
that are in contact.
With slight variations or modifications this may be carried out in several ways.
The frame of the machine is in each case constructed with suitable fixed or
stationary bearings for the journals of the centre or fixed roller and with slides or
guides in which the bearings of the top and bottom or movable rollers may move to
and fro as they are required to approach or recede from the centre or fixed one.
In the form and arrangement we at present prefer we carry two long bolts rods or
stays through the movable steps or bearings and on these rods we fix collars or nuts
which maintain these bearings at a fixed minimum distance apart. At both top and
bottom ends of the bolts or stays we place a sliding block or cross bar between which
and the bearing is inserted a spiral spring preferably compressed. To the top sliding
block is connected a screw free to rotate therein which is screwed through a cross bar
or cap on the top of the frame which sustains the weight of the rollers and acts in
opposition to the force of the springs when any material is being passed between
either pair of rollers. The raising of the screw raises the top roller out of contact
with the centre roller and the bottoin roller into contact with it and the raising may
be continued until any desired amount of pressure is applied by the bottom spring
and the lowering of the screw lowers the bottom roller out of contact with the centre
roller and the top roller into contact with it and by continuing the movement of the
screw in the same direction any desired amount of pressure may be exerted by the
top spring. We prefer that the springs when inserted in position should be under
compression so that the action or inovement of the screw is only required to bring
the rollers into contact. Instead of placing the screw at the top of the machine the
screw may be placed beneath and the movement reversed.
In a modification the bottom spring is dispensed with and a single spring above
the top roller inserted to act upon both top and bottom rollers. The bolts or stay
rods are passed down as before from a sliding block through the steps or bearings of
both top and bottom roller the bottom bearing resting upon nuts or collars at the
bottom and the top bearing upon collars or nuts placed at the desired distance from
the top.
In addition to these bolts or stays an additional bolt or bolts may be

page_text: inserted between the top bearing and the top sliding block by which the spring is
compressed. We prefer to make this additional bolt or stay as a prolongation of the
screw and run it down through the centre of the spring to a bracket attached or
affixed to the top bearing in which it is free to rotate. In this case also the position
of the screw may be reversed the screw and spring being placed below the bottom
roller.
"
In another arrangement the screw may be made to rotate in the top bar or bracket
and screwed into the sliding block by which the spring is primarily compressed. The
long stays or bolts pass down from a second sliding block placed immediately under
the first one either through or outside the top bearing and through the bearing of
the bottom roller and support the latter and two additional bolts compress the spring
between and connect the first sliding block with the top bearing. The screw is
screwed into the first sliding block and by turning the screw the rollers. are
simultaneously raised or lowered as before described. Or instead of rotating the
screw in the top bracket both of them may be provided with suitable threads to give
the desired movement.
In another arrangement where it is desirable to place the adjusting screw and
compressing mechanism or springs below the rollers two springs are placed below,
one to act upon the top roller and the other upon the bottom. roller. The bearings
of the rollers are supported upon long bolts or stays and two springs are inserted
between the bottoin bearing and the bottom sliding block of the bolts. A movable
adjusting cross bar is inserted between the two springs. The ends of the cross bar
are provided with holes through which the long bolts pass suitable collars or stops
being provided on the latter to lift the bearing of the top roller as the bottom roller
is brought into contact with the middle roller. This cross bar is raised and lowered
by a screw placed at any suitable position between the two ends preferably central
the lower end of the screw working in a fixed cross bar attached to the framing of
the machine. A single or double screw may be employed preferably a double one to
increase the speed at which the movement will be performed. By raising the cross
bar the rollers are lifted up until the bottom one is in contact with the centre roller
and by lowering the cross bar the top one is lowered into contact and pressure
exerted on the bottom spring connected thereto.
By a modification of some of the arrangements above stated we can obtain the
results we have in view by making the bearings of the top and bottom rollers fixed
and by connecting the bearing of the centre roller to the bolts or stays and lifting
it or lowering it into contact with the top or bottom roller by the operation of the
screw. The spring is compressed between two sliding blocks through which either
a prolongation of the screw or separate bolts pass. The screw is screwed into the
top bracket and lifts or lowers the bearing of the roller and the spring is compressed
in an upward or downward direction according to which of the rollers it is brought
into contact with. Or the screw may rotate in the top bracket and be screwed into
a third sliding block to lift and lower the roller the other two blocks serving to
transmit the pressure of the spring to the roller. Or instead of rotating the screw
in the top bracket both of them may be provided with suitable threads to give the
desired movement.
In another arrangement the top and bottom rollers may be mounted on an arm or
bracket pivoted to the side of the machine which is raised and lowered by a screw
and the bearing of the centre roller is mounted upon a spring or springs the pressure
of which may be exerted by an upward or downward movement of the central roller
as before described.
Or the central roller may be mounted on a radial arm or bracket with a lifting
screw to which one or two springs may be applied to exert pressure in the desired
direction. Or the central roller may be mounted on a radial arm or bracket with
a lifting screw with the springs applied to the upper and lower rollers suitable
arrangement being made to prevent the upper and lower rollers from being in
contact with the middle roller at the same time. In another arrangement the top
and bottom rollers may be raised and lowered simultaneously. or the middle roller

page_text: singly by the insertion or withdrawal of suitable inclines or wedges or by eccentrics
cams or cranks the springs being arranged in a similar manner to what we have
above described.
We find also that the rollers can be altered in position as required by a horizontal
or inclined movement instead of a vertical one the rollers being carried on a sliding
or pivoted bracket so that one can be removed and the other placed in contact with
a fixed top roller. Or the rollers may be mounted on a pivoted bracket or carrier
capable of being rotated so as to bring first one roller and then another into contact
with a fixed or geared one. The roliers would be held in contact by springs such as
described without the long bolts or stay rods.
It will be understood that without departing from our invention which is to
prevent more than two rollers being in contact at the same time other arrangements
or modifications of the methods of adjustment described might be adopted.

Improvements in Wringing and Mangling Machines.
We, JONATHAN BARNES, RICHARD WALTON KENYON, and WILLIAM HENRY KENYON,
of the firm of Entwisle & Kenyon, Limited, of Ewbank Works, Accrington, in the
County of Lancaster, Machinists, and JAMES LIGHTFOOT SHORROCK, of Hollins Lane,
Accrington, aforesaid, Mechanic, 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 :-
4
This invention relates to mangling or wringing machines for domestic or other
purposes with three rollers in which the bearings of one of the rollers, preferably
the central roller, are fixed or stationary, and is designed to provide for the moving
of either of the other rollers into contact with the central one or fixed one, while
maintaining them in such a position that one only will be in contact therewith at
one and the same time.
It consists essentially in constructing a three roller mangle with the bearings of
the top and bottom rollers so connected by bolts or otherwise, that they cannot
approach more closely towards each other, and will be raised and lowered together,
and at such a distance apart, that the two cannot be brought into contact with
the central roller at the same time, also in mechanism for raising and lowering the
top and bottom rollers simultaneously, and for applying the desired pressure to the
two that are in contact.
The invention will be fully described with reference to the accompanying drawings,
in which as examples, several modifications or ways of carrying it into effect are
illustrated.
The framing D is made with a slide d in which the bearings a and c of the
top roller A and bottom roller C can slide to and fro as they are required to approach
or recede from the centre or fixed one. The bearing b of the centre roller is fixed
to the framing D, so as to bear pressure upon it in either direction.
It is to be understood that the description in each case refers to one end of the
machine, and that similar mechanism is applied to both ends of the rollers.
Referring to Figs 1 and 2 in this arrangement the necessary pressure is applied
to both top and bottom rollers by a single spring E, placed above the top roller A,
which is compressed in an upward direction, when the top roller A is in operation,

page_text: and in a downward direction when the bottom roller C is in operation. The spring E
rests upon the top roller hearing a, and is compressed between it and two
sliding blocks F F¹ sliding together into the uppermost one F1, of which the screw H
is screwed to raise and lower them. The screw is fitted with a collar h, and rotates in
the top bar or bracket K, which is bolted to the framing, so that the screw does not
rise and fall. The roller bearing a is connected to the sliding block F by the
two short bolts e by which the spring E is compressed, and held in compression, and
by which the bearing a is raised, when the block F is raised by means of the screw H.
The second block F is held tightly against the block F' by the pressure of the
compressed spring E. The block F is connected with the bearing c of the bottom
roller C by two long stays or bolts f which pass through the block F, down the
bearing c, and through holes formed therein. The bolts f have a nut or collar at
both ends and support the bottom roller C and bearing c. By turning the screw H
in one direction into the block F, the top and bottom rollers are simultaneously
lifted, the top one out of contact and the bottom one into contact with the centre
fixed roller B, and by turning the screw H in the reverse direction, the top roller A
is forced down into contact with the central fixed roller B, and the bottom roller C
away from it, thus only one of the rollers A or C can be in contact with the
fixed roller at one and the same time.
Instead of rotating the screw H in the top bracket K, a screw with right and left
hand threads may be employed or with a fine and coarse thread, one of which
will screw into the block F₁, and the other into the bracket K, (see Figs 1^
and 1B.)
On
Referring to Figs 3 and 4 in this arrangement the pressure is applied to the top
and bottom rollers by two springs E and E¹, a separate one to each. The
bearings a and c of the top and bottom rollers A and C, are connected by two long
bolts, rods or stays f, carried or passed through the steps or bearings a and c.
the rods f we fix collars f¹ or nuts which maintain these bearings at a fixed minimum
distance apart. At both top and bottom ends of the bolts or stays, we place
a sliding block F and G or cross bar, between which and the bearing is inserted
the spiral spring E E¹ preferably compressed. To the top sliding block F is
connected a screw H, free to rotate therein, which is screwed through a cross bar or
cap K on the top of the frame which sustains the weight of the rollers, and acts in
opposition to the force of the springs E or E1, when any material is being passed
between either pair of rollers. The turning of the screw H raises the top roller A
out of contact with the centre roller B and the bottom roller C into contact with it,
and the raising may be continued until any-desired amount of pressure is applied by
the bottom spring E¹. The lowering of the screw H lowers the bottom roller C out
of contact with the centre roller B and the top roller A into contact with it, and by
continuing the movement of the screw in the same direction, any desired amount of
pressure may be exerted by the top spring E. We prefer that the springs, when
inserted in position, snould be under compression, so that the action or movement of
the screw is only required to bring the rollers into contact. Instead of placing the
screw at the top of the machine, the screw may be placed beneath and the inovement
reversed.
Referring to Fig 5 in this arrangement the pressure is applied to both rollers by
a single spring E above the top roller A: Two long bolts or stay rods f pass down
from the sliding block F with which the hearing a of the top roller A and the
bearing c of the bottom roller C both engage, the stays passing through holes or slots
in them. The bottom roller bearing c rests upon nuts or collars f at the end of the
stay rods, and is supported thereby, and the top roller bearing a rests upon and is
supported by the collars f¹ placed at the desired position to maintain the top and
bottom rollers such a distance apart, that they cannot both at the same time be
brought into contact with the centre roller B. The screw H is screwed through the
cross bar or cap K which is threaded to receive it, and the end bears upon the sliding
block F. A continuation of the screw is preferably carried down through the spring,
and by means of a collar engages with a bracket on the top of the bearing or step u.

page_text: The screw, however, may terminate with a collar placed below the block F. In
addition to the bolts or stays f, an additional bolt or bolts may be inserted between
the top bearing a and the sliding block F by which the spring E is compressed. We
prefer to make this additional bolt or stay as a prolongation of the screw, and run it
down through the centre of the spring E to a bracket attached or affixed to the top
bearing in which it is free to rotate as shown. By turning the screw H in one
direction, the top roller A is forced or pressed down against the centre roller B, and
the bottom roller is carried away from it, and by turning the screw in the reverse
direction, the top roller A is lifted out of contact with the centre roller B, and the
bottom roller C raised into contact with it. When the top roller A is in use, the
bearing a is forced upwards and compresses the spring E against the block F, and
when the bottom roller C is in use, the sliding block F is drawn down by the stays f,
and the spring E is compressed against the top roller bearing a which remains
stationary. In this case also the position of the screw may be reversed, the screw
and spring being placed below the bottom roller.
Referring to Figs 6 and 7, an arrangement is shown with the adjusting screw H
and the compressing mechanism placed below the rollers, two springs E E¹ being em-
ployed, one to apply pressure to the top roller and the other to apply pressure to the
bottom roller. The top roller bearings are supported by the collars or nuts f¹ upon
the upper ends of the long bolts or stays, which pass down through the bottom roller
bearings c and engage with the sliding block or cross bar F, and the second sliding
block G. A spring E is inserted (preferably compressed) between the bottom bearing c
and the sliding block or cross bar F, which applies pressure to the bottom roller C
when it is in use, and a second spring E¹ is inserted between the top block or cross
bar and the bottom sliding block G, which applies pressure to the top roller A
when it is in use. The stay rods ƒ pass through holes or slots in the top sliding.
block or cross bar F, the collars or nuts fl resting upon the block F, by which the
top roller bearings a are raised, when the block is moved upwards by the screw H.
Collars are also placed upon the stay rods f above the bottom roller bearings c to
maintain the rollers the desired distance apart. The cross bar F is raised and,
lowered by the screw H, which engages with a fixed cross bar G¹ bolted or fixe!
the framing D of the machine. The screw H is preferably a double ended scre
with right and left hand threads, screwing into both bars to increase the speed at
which the movement will be performed, but a single screw may be employed screw-
ing into either the bottom fixed cress bar G¹ or into the movable cross bar F, and
engaging with the other. By raising the cross bar F, the rollers are lifted up until
the bottom one C is in contact with the centre roller B, and by lowering the cross
bar F, the top roller A is lowered into contact with the centre roller.
Referring to Figs 8 and 9, the object of the invention can be attained by fixing the
bearings a and c of the top and bottom rollers A and C, and mounting the centre
roller B on bearings b, capable of sliding up and down, so that the centre roller B
may be brought into contact with either the top roller A or the bottom roller C, the
distance between the two fixed rollers being such that the roller B cannot be in
contact with both at the same time. The bearing b of the centre roller B is
connected to the bolts or stays f which engage with or pass through the two
sliding blocks F and G between which the spring E is compressed. A screw H passing
through the top cap or bar K raises and lowers the blocks F and G, and with them
the centre roller. When the centre roller B is in contact with the bottom
roller Cand in use, the block G is raised by the stay rods f and collars f¹, and the
spring E compressed in an upward direction, and when it is in contact with the top
roller A and in use, the rods f and block F are drawn down and the spring E
compressed from above. The spring E is held compressed between the sliding
blocks F and G, through which either a prolongation of the screw H or separate
bolts pass.
The screw H is screwed into the top bracket K and lifts or lowers the
bearing of the roller B and the spring E.
Referring to Figs 10 and 11, another arrangement is shown of top and bottom
rollers A and C, mounted in fixed bearings a and c, and a central roller B mounted

page_text: in movable bearings, so that it may be moved into contact as required with either
of the other rollers. The screw H rotates in the top bracket K and is screwed into
an additional sliding block F to lift and lower the centre roller B, the two sliding
blocks F and G serving to transmit the pressure of the spring to the roller. Four
stay rods are employed, two extend from the sliding block F to the centre roller
bearing b, and engage with and support it, passing through the sliding block G, the
other two extend from the sliding block F¹ to the sliding block G and engage with
and support it, compressing the spring. If desired, all four stays inay pass down to
the centre roller bearing c. Or instead of rotating the screw in the top bracket,
both of them may be provided with suitable threads to give the desired movement
as indicated in Figs 1^. 13.
'
Referring to Fig 12 in this arrangement, the bearings a and c of top and
bottom rollers A and C are mounted on a swinging arm or bracket M pivoted to the
frame D of the machine. The bearings b of the central roller B are mounted in the
frame D with springs E, E¹, top and bottom. The arm or bracket M is raised and
lowered by a screw H to bring either the top or bottom roller into contact with the
centre roller B, the bearings a and c being set sufficiently far apart in the bracket M
that both of these rollers cannot be in contact with the roller B at the same time.
When the top roller A is in contact with the centre roller B and in use, pressure is
exerted by the bottom spring E', and when the bottom roller C is in contact with
the centre roller B and in use, pressure is exerted thereon by the top spring E.
Referring to Fig 13 another arrangement is shown in which the top and
bottom rollers A and C are mounted in fixed bearings, and the central roller B in
movable bearings, so as to be capable of being brought into contact with either
of the other two rollers. The bearing 6 of the central roller B is mounted upon
radial arm N pivoted at m. To the arm N are applied the two springs E, E¹,
exert the desired pressure, one in one direction and the other in the reverse
ection. The roller B is moved up or down as required by the handle P, which is
held in the desired position by a pin p or other suitable catch. Instead of the
handle P a screw may be applied to the swinging arm N to raise and lower it.
The central roller may be mounted on a pivoted radial arm or bracket with a
lifting screw, with a spring applied to the upper and lower rollers, suitable arrange-
ment being made to prevent the upper and lower rollers from being in contact with
the middle roller at the same time. In another arrangement the top and bottom
rollers may be raised and lowered simultaneously, or the middle roller singly by the
insertion or withdrawal of suitable inclines or wedges or by eccentrics, cams or cranks,
the springs being arranged in a similar manner to what we have above described.
We find also that the rollers can be altered in position as required by a horizontal
or inclined movement, instead of a vertical one, the rollers being carried on a sliding
or pivoted bracket, so that one can be removed, and the other placed in contact with
a fixed top roller. Or the rollers may be mounted on a pivoted bracket or carrier
capable of being rotated so as to bring first one roller, and then another into contact
with a fixed or geared one. The rollers would be held in contact by springs such as
described without the long bolts or stay rods. Such a rotating bracket may either
be pivoted eccentric to the centre roller so as to alternately bring one of the others
into contact with it. Or it may be concentric, and pivoted on the axis of the ecntre
roller, and a spring be applied outside the rotating frame-either above or below-
to give the desired pressure to the rollers in contact.
It will be understood that without departing from our invention, which is to
prevent more than two rollers being in contact at the same time, other arrangements
or modifications of the method of adjustment described, might be adopted.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, we declare that what
