IMPROVEMENTS IN WASHING AND WRINGING AND MANGLING MACHINES
Year: 1886

page_text: I, EDWARD NEWTON KENWORTHY, of 1 Fielding Street, Oldham, in the County
of Lancaster, Machine Maker, do hereby declare the nature of my invention for
IMPROVEMENTS IN WASHING AND WRINGING AND MANGLING MACHINES" to be
as follows:-
"
1
Firstly. Of an improved arrangement of gearing for giving motion to the rollers;
on the roller shaft which has stationary bearings is firmly fixed an internal spur
wheel which has on the back of it, and forming a part of it, another spur wheel for
the purpose of giving motion to the top roller.
A pinion is employed to drive the internal wheel; the bearing for the shaft of
this pinion is obtained by means of a fixing secured to the frame side of the
machine, and this fixing can be so formed as to completely form a guard for the
wheelwork; on the pinion-shaft, and at the other end of it from the pinion is
secured a fly-wheel, or pulley, for communicating motion to the machine.
Secondly. Of an improved arrangement of mechanism whereby an oscillatory
motion is imparted to a shaft which is placed at the back of the machine, and
which in conjunction with a lever, serves the purpose of giving an up and down
notion to the washer of the machine. To that end of the back-shaft, which is
nearest to the wheel-work is fastened a crank which carries on its pin one end of
a link; the other end of the link is carried by a pin fixed to a spur-wheel. This
spur-wheel is carried by the fixing which carries the pinion-shaft; it is so arranged
that a rotary motion of the spur-wheel causes an oscillatory motion in the back-
shaft.
The spur-pinion used for driving the before mentioned internal wheel is also
used for driving this spur wheel, and a provision is made to allow the fly-wheel
shaft and its pinion to have a lateral movement whereby the pinion is alternately
in gear with the internal wheel, and thus moving the rollers, or with the spur-
wheel which will cause the back-shaft to move. The pinion shaft is secured in
either of these positions by one or other of two grooves cut in it, and into which
enters a movable pin which passes through a hole in the pinion shaft bearing.
The required movement of the back-shaft may be also obtained by using an
eccentric, the sheave of which works loosely on a boss of the fixing, through which
the pinion-shaft before mentioned passes, and the end of the rod is attached to the

page_text: crank. The lateral movement of the pinion shaft allows projecting pieces on the
pinion to enter corresponding recesses in the eccentric sheave, so that the motion of
the pinion shaft is given to the eccentric.
.
Thirdly. Of an improved means of securing the "Washer 'to the end of the
lever which gives to it its vertical movement, and also of guiding the same within
the tub.
The handle of the Washer contains a slot through which passes, at right angles
to the slot, one or more pins; the end of the lever enters this slot and one of the
pins is forced into an opening in the end of the lever. This opening in the end of
the lever is partially closed by a tongue-piece, in the form of a lever, having its
fulcrum in the first lever and carrying at the opposite end from the tongue-piece a
weight; this weighted lever is sufficient to keep the opening in the first lever
nearly closed and so prevent the pin in the Washer handle from being disengaged
from the lever unless some external force is applied.
"
For guiding the "Washer two projecting ribs are secured to the inside of the
tub, being placed in a vertical plane which passes through the centre of the tub
and is at right angles to the back-shaft. The inner edges of these ribs serve as a
guide for the Washer in its up and down movement.
Note. The second and third sections relate more particularly to that description
of Washing Machine in respect of which Letters Patent were granted to Edward
Newton Kenworthy, dated 2nd June 1877, No 2156.
Fourthly. Of an improved arrangement of levers for applying pressure to the
rollers of Wringing and Mangling Machines.
A lever is attached to the frame side so as to be hinged at some point above the
top roller step; the other end of this lever is hinged to a second lever the lower
end of which is in contact with the top roller step, or, this end may be arranged so
as to form the top roller step. When the rollers are not under pressure these
levers are inclined to one another, and it is evident that if their common joint be
moved in one way in a horizontal direction the levers will straighten and thus
cause a pressure between the rollers which may be made very great for a moderate
application of force in the horizontal direction. To obtain the horizontal move-
ment a rod is attached to the common joint of the levers, and having on it a
screw-thread commencing at its other end; a spiral or other spring is put on this
rod and comes against the frame side, and then a hand wheel screws on the rod
and presses against the other end of the spring. The object of the spring is to
permit the top roller to lift when articles are being passed through the rollers, and
this lifting of the roller compresses the spring, and this causes a greater force to act
on the levers in the horizontal direction and which can, by a suitable strength of
spring, be made to neutralise the loss of pressure between the rollers consequent
upon the bending of the levers away from the perpendicular. A stop on the frame
side prevents the levers from being brought too nearly in a straight line This
method of applying the pressure to the rollers causes it to be nearly uniform for a
varying thickness in the articles passed through them.
If preferred this arrangement of the levers may be applied so as to put pressure
on the bottom roller instead of the top one, in which case the top roller must have
its bearings fixed.
The pressure may also be applied to both sets of levers by using only one spring
and hand-wheel, placed in a suitable position between the frame sides, and then the
arrangement is such that the spring acts upon each of the horizontal levers
previously referred to, and so causes the rollers to be put under pressure.

I, EDWARD NEWTON KENWORTHY, of 1 Fielding St. Oldham, in the County of
Lancaster, Machine Maker do hereby declare the nature of my invention for
"IMPROVEMENTS IN WASHING, AND WRINGING, AND MANGLING MACHINES" and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
Firstly. Of an improved arrangement of gearing for giving motion to the rollers;
on the roller shaft which has stationary bearings is firmly fixed an internal spur
wheel which has on the back of it, and forming a part of it, another spur wheel for
the purpose of giving motion to the top roller. A pinion is employed to drive the
internal wheel; the bearing for the shaft of this pinion is obtained by means of a
fixing secured to the frame side of the machine, and this fixing can be so formed as
to completely form a guard for the wheelwork; on the pinion shaft, and at the other
end of it from the pinion is secured a fly-wheel, or pulley, for communicating motion
to the machine.
Secondly of an improved arrangement of mechanism whereby an oscillatory
motion is imparted to a shaft which is placed at the back of the machine and
which in conjunction with a lever, serves the purpose of giving an up and down
motion to the washer of the machine. To that end of the back shaft which is
nearest to the wheelwork is fastened a crank which carries on its pin one end of
a link; the other end of the link is carried by a pin fixed to a spur wheel. This
spur wheel is carried by the fixing which carries the pinion-shaft; it is so
arranged that a rotary motion of the spur wheel causes an oscillatory motion in
the back-shaft.
The spur-pinion used for driving the before mentioned internal wheel is also
used for driving this spur wheel, and a provision is made to allow the fly-wheel
shaft and its pinion to have a lateral movement whereby the pinion is alternately
in gear with the internal wheel, and thus moving the rollers or with the spur-
wheel which will cause the back-shaft to move. The pinion-shaft is secured in
either of these positions by one or other of two grooves cut in it, and into which
enters a movable pin which passes through a hole in the pinion-shaft bearing. The
required movement of the back shaft may be also obtained by using an eccentric,
the sheave of which works loosely on a boss of the fixing through which the pinion
shaft before mentioned passes, and the end of the rod is attached to the crank.
The lateral movement of the pinion-shaft allows projecting pieces on the pinion to
enter corresponding recesses in the eccentric sheave so that the motion of the
pinion-shaft is given to the eccentric.
Thirdly of an improved means of securing the "Washer " to the end of the lever
which gives to it its vertical movement, and also of guiding the same within the
tub. The handle of the Washer contains a slot through which passes at right
angles to the slot one or more pins; the end of the lever enters this slot and one of
the pins is forced into an opening in the end of the lever. This opening in the end
of the lever is partially closed by a tongue-piece in the form of a lever having its

page_text: fulcrum in the first lever and carrying at the opposite end from the tongue-piece a
weight; this weighted lever is sufficient to keep the opening in the first lever
nearly closed and so prevent the pin in the Washer-handle from being disengaged
from the lever unless some external force is applied. For guiding the "Washer "
one or more projecting ribs are secured to the inside of the tub. The inner edges
of these ribs serve as a guide for the Washer in its up and down movement.
The second and third sections relate more particularly to that description of
Washing Machines in respect of which Letters Patent were granted to Edward
Newton Kenworthy dated 2nd June 1877 N° 2156.
Fourthly of an improved arrangement of levers for applying pressure to the
rollers of Wringing and Mangling Machines. A lever is attached to the frame
sides so as to be hinged at some point above the top roller step; the other end of
this lever is hinged to a second lever the lower end of which is in contact with the
top roller step, or, this end may be arranged so as to form the top roller step.
When the rollers are not under pressure these levers are inclined to one another,
and it is evident that if their common joint be moved in one way in a horizontal
direction the levers will straighten and thus cause a pressure between the rollers
which may be made very great for a moderate application of force in the
horizontal direction. To obtain the horizontal movement a rod is attached to the
common joint of the levers, and having on it a screw-thread commencing at its
other end; a.spiral or other spring is put on this rod and comes against the frame
side, and then a handwheel screws on the rod and presses against the other end of
the spring. The object of the spring is to permit the top roller to lift when
articles are being passed through the rollers, and this lifting of the roller compresses
the spring, and thus causes a greater force to act on the levers in the horizontal
direction, and which can, by a suitable strength of spring, be made to neutralise
the loss of pressure between the rollers consequent upon the bending of the levers
away from the perpendicular. A stop, on the frame side prevents the levers from
being brought too nearly into a straight line. This method of applying the pressure
to the rollers causes it to be nearly uniform for a varying thickness in the
articles passed through them If prefered this arrangement of the levers may be
applied so as to put pressure on the bottom roller instead of the top one, in which
case the top roller must have its bearings fixed. The pressure may also be applied
to both sets of levers by using only one spring and hand-wheel, placed in a
suitable position between the frame sides, and then the arrangement is such that
the spring acts upon each of the horizontal levers previously referred to and so
causes the rollers to be put under pressure.
And in order that my said invention may be fully understood I herein give
reference to an accompanying sheet of Drawings illustrative thereof, the same
letters of reference indicating corresponding parts in all the figures.
Fig. 1. represents a sectional elevation of a combined Washing, Wringing, and
Mangling Machine with my improvements applied thereto. Fig. 2 is a side
elevation of the same. Figs. 3 & 4 shows a front and sectional elevation of the
gearing used for imparting motion to the rollers and to the "Washer." Fig. 5 is
an elevation and Fig. 6 a section showing the arrangement for applying pressure
to the rollers. Figs. 7 and 8 show the lever to which the "Washer" is attached.
For giving motion to the rollers I employ an internal spur-wheel A, which is
securely fixed to the bottom roller shaft B, and at the back of which is a spur-
wheel C; the wheel C gears with a similar one D fixed on the top roller shaft, so
that the rotation. of the top roller is ensured. To drive the internal wheel A a
pinion E is used and the bearing for the shaft of this pinion is formed out of the
At the
fixing F; this fixing is fastened to the sides of the machine at G, H, I.
end of the pinion shaft is secured the fly-wheel M. The fixing F has a pocket J,
The
inside of which is a boss K and upon which turns the spur-wheel L.
pinion E, and its shaft admits of a lateral movement such that it may be
alternately in gear with the internal wheel A. and the wheel L; it is maintained in
either position by a balanced catch N, passing through the bearing and entering a

page_text: groove cut in the shaft. A projecting pin on the wheel L carries one end of the
connecting link O, the other end of the link being attached to the crank P. If
the pinion E is in gear with wheel A the rollers are put in motion by the rotation
of the fly-wheel, and if in gear with wheel L, the rotation of the fly-wheel causes
an oscillatory movement of the back-shaft which conveys, by means of the lever b,
the requisite motion, to the "Washer."
For a wringing and Mangling Machine I prefer to have the fly-wheel M and the
pinion E in one casting, and to make the bearing in the fixing F as large in
diameter as the pinion E, and since lateral movement is not required, the balanced
catch N will serve to keep the fly-wheel in position for turning the rollers, or if
lifted out of the groove will allow it to be taken away.
For applying pressure to the rollers I use two levers or links Q R, which are
jointed at S, of which R forms a bearing for the top roller shaft B, the other
lever being free to move about the fixed pin T. A rod U, by means of its
hooked end, takes hold of one or other of the levers Q, R at or near to their joint S
and on this rod is placed a spring X as shewn. The hand-wheel Y, by screwing
on the rod U, applies the pressure to the rollers. To prevent the levers Q, R,
from being brought in a straight line, a projecting piece s on one of them comes in
contact with the frame side as shewn. To allow of adjustment the bracket Z,
which carries the pin T, can be moved up or down on the bracket Z,, to which it
is secured, whilst the set screw, y, serves to fix it in the required position. The
bracket Z, is bolted to the machine. The lever for working the "Washer" is
made in two parts which are hinged together at a. The piece b is connected with
the back-shaft from which it derives its movement; whilst the other piece c is a
lever having its fulcrum at a and weighted at d to keep it in the position shown.
To attach the "Washer" to the lever the pin in the handle is forced in the
opening of the lever, and pushes down the tongue-piece g of the part c until it
has got past it when it is in its right place. Directly the pin has passed over the
tongue-piece, the piece c returns to its normal position, and the "Washer" handle
is held secure until released, which is effected by pressing downwards on the piece c
at h, and at the same time withdrawing the handle from the lever,
For guiding the "Washer" in the tub, one or more ribs, or feathers, X, X, are
attached to the sides as shown in figures 1, and 2.
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:
(1.) The gearing for giving motion to the rollers of Wringing and Mangling
Machines, and the gearing for working the "Washer" in Washing Machines,
substantially as herein shown and described.
(2.) The combination of levers and springs for applying the pressure to the
rollers of Wringing and Mangling Machines substantially as herein shown and
described.
(3.) The lever which gives the "Washer" an up and down movement, and the
ribs used for guiding the "Washer," substantially as herein shown and described.
