page_text: I JOHN PORRITT ROTHWELL of Clifton St Lytham, in the County of Lancaster,
Veterinary Surgeon, do hereby declare the nature of my Invention for "IMPROVE-
MENTS IN MACHINES FOR WRINGING AND MANGLING FABRICS to be as follows:-
"
My improvements relate in the first place to the construction of side frames for
wringing or mangling machines, in the second place to an improved arrangement
for applying pressure on the top roller and taking off such pressure when required,
in the third place to the manner of fixing the rollers on to their shafts, in the fourth
place to improved means for gearing up and driving the rollers, and in the last
place to some modification of the castor or foot described in the patent granted to
me No 5361 Nov. 10th A D..1883. the principal object being to lessen the cost of
such machines and to reduce the great wear and tear.
To this end I form the frame of a wringing or mangling machine either wholly
or partly of solid wrought iron or other, metal rods instead of tubular as heretofore
has been the case, the rods forming the sides of the frame being, about 7/8 of an
inch in diameter and the rods forming the stays connecting the two sides together
of about 5/8 of an inch in diameter. When the frame consists wholly of solid
wrought iron or other metal rods, each side thereof is formed of two vertical rods
the bottom ends of which are connected by means of sockets or joints to cross
wrought iron or other metal rods, or direct onto feet or castors, the connection
being effected by fixing the ends of the vertical cross rods into the socket or joint
or feet or castors by means of set screws or casting or screwing the same thereto.
The top halves of the vertical rods are arranged parallel in order to suit the
arrangement for applying and taking off the pressure of the top roller and an
arrangement described in my patent N° 5631 A D. 1883, for mounting the rollers on
anti-friction pulleys. The lower halves of the vertical rods may also be parallel or
bent in any suitable shape and connected in the mauner described either to the
cross rods or direct to feet or castors.
The latter are provided with pegs either at the side or top thereof, or formed on
a collar which is slipped on the vertical rod and fixed above the feet or castors by
means of set screws or otherwise onto which a single or crossed double stay, formed
of wrought iron or other metal rods or cast iron, is hooked and fixed by means of
set, screws or otherwise which connect the sides of the framing firmly together.
The caps of the said castors or feet I provide with a lug on each side which when
the cap is screwed against the body of the castor or foot, will fit into two corre-
sponding recesses formed therein which will prevent the cap from giving way.

page_text: Similar stays are also employed in a similar manner below the bottom and above
the top roller for the purpose of giving the framing ample firmness.
The bottom half of the said sides of the framing may be formed of cast iron and
the vertical of solid wrought iron or other metal rods forming the top half, fixed,
screwed or cast thereto. The castors or feet are in this case screwed to the inside
of the framing by means of bolts or otherwise and also provided with a peg onto
which the single or crossed double stay is hooked and held down in its position by
means of lugs cast on the side of the framing. Cross brackets carrying the anti-
friction pulleys on which the shafts of the top and bottom rollers run or rotate
respectively are arranged to slide up or down in the said vertical, parallel, wrought
iron or other metal rods forming the top half of the side of the frame and may be
fixed in any required position by means of set screws cast thereon. The said
bottom bracket is provided with a boss or otherwise, carrying a part of the driving
gear The said cross brackets are also provided with a slotted part through which
the shaft ends of the roller pass and prevent the rollers from moving sideways, thus
retaining the same in their proper positions. A spiral spring is put on each of the
said vertical, wrought or other metal rods between the said cross bracket and a
cross bracket above the latter which is arranged to slide on the said vertical metal
rods on each end frame and bearing against the said springs. At a suitable
distance apart from the said sliding cross bracket, another similar bracket is suitably
fixed on the top of the metal rods, between and in which a lever formed with two
inclined planes and pivots, is arranged on each end frame to depress the said springs.
or release them as required. Tables are fixed on each side of the roller onto the
end frame by means of collars being arranged to slide on the rods of the end frames.
These collars are provided with set screws and snugs which engage a metal strip
screwed underneath the table can be raised or lowered to suit convenience and
fixed in its required position by means of the said set screws or stop collar. In
fixing the rollers onto their shafts I use a disc on each end of the roller which fits
exactly onto the shaft and is provided at its inner surface near its periphery with
a suitable number of prongs of the shape of a cross or otherwise which are driven
into the material until the said disc bears against the end of the roller. These
means for fixing rollers on their shafts will give the roller at each end an indepen-
dent support if the shaft should not exactly fit the hole of the roller and will also
prevent the material from coming loose, keeping the roller perfectly secure and
true at the ends, doing away with hoops, and wedging or keying on. My improved
means for gearing and driving the rollers of a mangling or wringing machine,
consist in fixing at the driving side of the machine on each shaft end a worm,
wheel. The worm wheels I make of a diameter sufficiently large to bring them"
into gear with each other and arrange horizontally a shaft provided with a worm
to gear either into the worm-wheel of the bottom roller or top roller, or I make the
worm-wheels of a less diameter so as not to come into gear with each other and
arrange the worm to gear between the said worm wheels for the purpose of
driving both the bottom and top rollers.
The said worm wheels may also be driven from a shaft arranged vertically on the
side thereof and provided with a right and left hand worm. The worms and worm
wheels may be single, double, treble or more, threaded, according to the speed
required, and the worm-shaft provided with a fly-wheel and driven either by hand
foot-treddle, or steam power. By these means I am enabled to obtain more power
and any required speed and to dispense with the ordinary spur wheel gearing, for
transmitting the motion from the bottom roller to the top.

COMPLETE SPECIFICATION.
I, JOHN PORRITT ROTHWELL, of Clifton Street, Lytham, in the County of
Lancaster Veterinary Surgeon, do hereby declare the nature of my invention for
IMPROVEMENTS IN MACHINES FOR WRINGING AND MANGLING FABRICS" and in.
what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
My improvements relate in the first place to the construction of side frames for.
wringing or mangling machines, in the second place to an improved arrangement
for applying pressure on the top roller and taking off such pressure when required,.
in the third place to the manner of fixing the rollers on their shafts in the fourth
place to improved means for gearing up and driving the rollers, and in the last'
place to some modification of the castor or foot described in the patent granted to
me N° 5361 Nov. 10th 1883, the principal object being to lessen the cost of such,
machines and to reduce the great wear and tear.
And in order that my invention may be better understood I have caused to be
appended hereunto one sheet of drawings marked with letters of reference corre-
sponding letters indicating like parts in the various figures.
Fig 1 on the said drawing represents a side view. Figs 2, 3 and 4, are end
views.
Figs 5 and 6 plans of end frames and bottom stay.
Figs 7, 8, 9 and 10 front and side views respectively of foot or castor and stay."
Fig 11 is a side view of end frame.
Figs 12 and 13, section and plan of roller and disc respectively.
In carrying out my invention I form the frame of a wringing or mangling
machine either wholly or partly of solid wrought iron or other metal rods instead
of tubular as heretofore has been the case the rods forming the end frames A
see Figs 1. 2 and 5, being about of an inch in diameter and the rods forming.
the stays connecting the side frames A together of about g of an inch in
diameter.
When the frame consists wholly of solid wrought or other metal rods, each end'
frame thereof is formed of two vertical rods a see Figs 1, 2 and 3, the bottom ends'
of which are connected by means of sockets or joints b to horizontal cross wrought
iron or other metal rods a¹ or direct onto feet or castors B, the connection being
effected by fixing the vertical rods a into the sockets or joints b or feet or castors B
by means of set screws or casting or screwing the same thereto.
Such end frames may also consist of a continuous length of iron or other metal.
rods a as illustrated in Figs 4 and 11. In this case the foot or castor is dispensed
with, and a wheel B¹ arranged to rotate on the rod a, and kept in its position by
means of the stay ends c¹ and the bend of the rods a. The top halves of the
vertical rods a. Figs 1, 2 3. 4 and 11 are arranged parallel in order to suit the
arrangement for applying and taking off the pressure of the top roller and arrange-
Iment for mounting the rollers on anti-friction pulleys described in my patent
N° 5361 A D. 1882. The lower halves of the vertical rods a may also be parallel
or bent in any suitable shape and connected in the manner described either to the '
cross rods a¹ or direct to the feet or castors B.

page_text: In some cases the latter are provided at their inner sides with pegs c similar
to what is shown in Figs 7 and 8 or the said pegs may be formed on a collar
which is slipped on the vertical rods a and fixed above the fect or castors B. by
means of set screws or otherwise.
The said pegs engage the ends c¹ of a single or double cross stay C formed of
wrought iron or other metal rods a² see Figs 7 and 8. or of cast iron being hooked
thereon and fixed in position by means of set screws or otherwise which connect
the end frames firmly together.
. Another method consists in forming the stay ends c¹ which may be partly of
cast iron and wrought iron, or other metal rods see Figs 1, 2. 4. 5 and 11. with a
horizontal hole and cap b¹ to engage the cross rod a¹ and enable an easy fixing and
ready removal when required, or when the said end frames A consist wholly or
partly of cast iron sec Figs 9 and 10. the same are cast with a slot b² above each
foot, which slots engage, the hook-like shaped stay ends c² bearing against the
outside of the end frame C. On the top of the said ends a projection 63 is cast on
which lays itself against the inside of the end frames A Another projection c³ being
formed above each slot b², prevents the stay C from getting loose. Similar stays D
and E are also employed in a similar manner below the bottom roller F and above
the top roller G for the purpose of giving the framing ample firinness.
The caps d of the castor or foot BI provide on each side with lugs c¹ see
Figs 1, 7, and. 8 which when the said cap is screwed against the body of the castor
or foot B, will fit into two corresponding recesses formed therein which will
prevent the cap d from giving way.
The bottom half of the said end frames may be formed of cast iron see Fig 3.
and vertical solid wrought iron or other metal rods a forming the top half, fixed.
screwed or cast thereto.
The castors or feet B are in this case screwed against the inside of the end
frames by means of bolts e or otherwise and also provided with pegs c onto which
the single or double cross stay C is hooked and held down in its position by means
of lugscast on the inside of the end frames A.
Cross brackets H and H see Figs 1, 2 and 3, carrying the anti-friction pulleys I
on which the shafts K and L of the top and bottom rollers E and G run, respec-
tively guiding the latter, are arranged to slide up or down on the vertical parallel
wrought iron or other metal rods a forming the top half of the end frames A and may
be fixed in any required position by means of set screws. The bottom bracket H is
provided with a boss g or otherwise arranged to the bevel wheel and fly-wheel M.
The cross brackets H are provided with a slotted part i through which the ends of
the shaft, K. and L. of the rollers E and G pass respectively and prevent the rollers F
and G from moving side-ways, thus retaining the same in their proper positions
during their rotation. A spiral spring N is placed on each of the vertical wrought
or other metal rods a and situated between the top cross bracket H and another
cross bracket O both capable of sliding.
At a suitable distance apart from the cross bracket O another similar bracket P
is suitably fixed on the top of the metal rods a between and in which a lever Q,
formed with two inclined surfaces c¹ and pivots 1, is arranged on each end frame
for the purpose of depressing the said springs N or release them as required.
Tables R are fixed on each side of the rollers F and G onto the end frames by
means of collars being arranged to slide on the rods and provided with set screws
and snugs which latter engage a metal strip m screwed underneath the table. The
latter may be raised or lowered to suit convenience and fixed in its required
position by means of the said set screws and stop collars..
In place of the latter snugs e¹ may be formed on the boss n of the lower cross
bracket H and the strip m of the table R engaged thereon, see Figs 1, 2, and 3.
My improved means for gearing and driving the rollers of a mangling or wringing
machine consists in fixing at the driving side of the machine on each shaft end K
and La worm wheel. Such worm wheels I may make of a diameter sufficiently
large to bring them into gear with each other and arrange horizontally a shaft

page_text: provided with a worm to gear either into the worm of the bottom roller or top
roller or I make the worm wheels of less diameter so as not to come into gear with
each other and arrange the worm to gear between the said worm wheel for the
purpose of driving both the bottom roller and the top roller. The said worm
wheels U, see Figs 1 and 2 may also be driven from a shaft V arranged vertically
on the side thereof carried by the bracket and provided with a right and left
hand worm wand x which arrangement I find to be most convenient and I have
therefore illustrated in the drawings. The worms and worm wheels may be single
double treble or more threaded according to the speed required and the worm
shaft driven either by hand, foot-treddle or steam-power.
By these means I am enabled to obtain more power and any required speed and
to dispense with the ordinary spur wheel gearing for transmitting motion from the
bottom roller to the top.
The attachment of the rollers F and G onto their shafts K and L see Figs 12
and 13 is effected by the use of a disc T employed on each end of the rollers F
and G fitting exactly onto the shafts K and L and provided at its inner surface
near its periphery with a suitable number of cross or other suitably shaped
prongs o which are driven into the material of the rollers F and G until the
disc T bears against the end of the rollers.
These means of fixing rollers on their shafts will give the roller at each end an
independent support if the shaft should not exactly fit the hole of the roller and
will also prevent the materials from coming loose keeping the rollers perfectly
secure and true at the ends doing away with hoops and wedging or keying on.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
-
In a machine for wringing and mangling fabrics.
