Improvements in Mangling or Wringing Machines and the like
Laundry Machines.
We, JOHN RICHARD BELL, of West View, Halfway, near Eckington, Colliery
Deputy, and WILLIAM WOODS, of Sheepcote Hill, Killamarsh, Engineer, both in the
County of Derby, do hereby declare the nature of our said invention to be as
follows:-
The object of our invention is to produce a machine which shall be more con-
venient to use and do work more quickly than similar machines as ordinarily con-
structed.
Although our invention is applicable to several kinds of laundry machines in
which rollers are employed, as in washing, wringing, mangling, ironing and the
like processes for washing and cleaning clothes, a description of it as applied to
a washing and wringing machine will suffice.
In such a machine as ordinarily constructed two rollers are employed, and the
articles to be wrung or mangled are laid on a board in front of the machine so
that they can be entered between the rolls through which they are drawn by the
revolving rolls actuated, either by hand or motive power. The articles having
passed through this pair of rolls have to be collected from the back of the machine
either by reaching over the rollers, or by the attendant going round to the back
of the machine. In some processes the articles are passed a second or more times
through the said rollers.
In our improved machine we employ three rollers, one above another. The
general arrangement of the bearings, framing, gearing, springs and other appliances
being somewhat similar to mangling and wringing machines with two rollers as
ordinarily made.
In combination with the three rollers, however, we employ an endless band of
some suitable flexible material such for example as india-rubber, canvas, felt, or
a combination of materials as may be found most suitable for the purpose. This
endless band we make of approximately the same width as the rollers and of
sufficient length to allow of its being passed singly over and between the top and
middle rollers so that the front of the top roll is entirely covered by one thickness
of the said band, thence around the back of the middle roller and between it and
the bottom roller to the front, so that the front of the bottom roller is likewise
covered. The band being made long enough to pass from the underside of the
bottom roller to the upper side of the top roller without being sufficiently tight
to be put into tension.
It will thus be seen that the path of the band would be in a downward direction
round the front portion of the circumference of the top roll, around the back
portion of the circumference of the middle roll, and around the front portion of
the circumference of the bottom roll, and thence along the back of all the rollers
in an upward direction to the top roll again.
By this arrangement an article entered between the top and middle rollers,

page_text: would be conveyed by means of the said endless band around the back portion of
the circumference of the middle roll and between the middle and bottom rollers
where it would be delivered upon a suitably arranged receiving board, having
passed through two pairs of rolls instead of one pair.
In some cases we provide the top and bottom rolls with flanges so as to prevent
the endless band from running off the rolls at either end.
The gearing of our improved machine we arrange so that the bottom roll is the
one which is driven, as in that way the endless band would always be in tension
on its downward passage between the rolls and would loosen or become slack on
its upward course behind the rolls.

Improvements in Mangling or Wringing Machines and the like
Laundry Machines.
We, JOHN RICHARD BELL, of West View, Halfway, near Eckington, Colliery
Deputy, and WILLIAM WOODS, of Sheepcote Hill, Killamarsh, Engineer, both in the
County of Derby, do hereby declare the nature of our said invention and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement:-
-
The object of our invention is to produce a machine which shall be more con-
venient to use and do work more quickly than similar machines as ordinarily con-
structed.
Although our invention is applicable to several kinds of laundry machines in
which rollers are employed, as in washing, wringing, mangling, ironing, and the
like processes for washing and cleaning clothes, a description of it as applied to
a washing and wringing machine will suffice.
In such a machine as ordinarily constructed two rollers are employed, and the
articles to be wrung or mangled are laid on a board in front of the machine so
that they can be entered between the rolls through which they are drawn by the
revolving rolls actuated, either by hand or motive power. The articles having
passed through this pair of rolls have to be collected from the back of the machine
either by reaching over the rollers, or by the attendant going round to the back
of the machine. In some processes the articles are passed a second or more times
through the said rollers.
Our invention will be better understood on reference to the accompanying sheet
of drawings, in which,
Fig. 1. is a front elevation of one of our improved machines.
Fig. 2. is an end elevation, and,
Fig. 3. is a section taken through the centre of the machine on the line, A., B.
The same letters refer to similar parts throughout the several views.
In our improved machine we employ three rollers, A, B, C, one above another.
The general arrangement of the bearings, framing, gearing, springs and other
appliances being somewhat similar to mangling and wringing machines with two
rollers as ordinarily made.
In combination with the three rollers, however, we employ an endless band, D,
of some suitable flexible material such for example as india-rubber, canvas, felt,
or a combination of materials as may be found most suitable for the purpose.
This endless band we make of approximately the same width as the rollers and of

page_text: sufficient length to allow of its being passed singly over and between the top. and
middle rollers so that the front of the top roll, A, is entirely covered by one thick-
ness of the said band, thence around the back of the middle roller, B, and between
it and the bottom roller, C, to the front, so that the front of the bottom roller, C,
is likewise covered. The band being made long enough to pass from the underside
of the bottom roller to the upper side of the top roller without being sufficiently
tight to be put into tension, as shewn by the dotted lines in Fig. 2.
It will thus be seen that the path of the band would be in a downward direction
round the front portion of the circumference of the top roll, around the back
portion of the circumference of the middle roll, and around the front
portion of the circumference of the bottom roll, and thence along the back
of all the rollers in an upward direction to the top roll again.
By this arrangement an article entered between the top and middle rollers,
would be conveyed by means of the said endless band around the back portion of
the circumference of the middle roll, B, and between the middle and bottom rollers,
where it would be delivered upon a suitably arranged receiving board, E, (as
indicated by the arrows), having passed through two pair of rolls instead of one
pair.
In some cases we provide the top and bottom rolls with flanges, F, as shewn in
Fig. 1. so as to prevent the endless band from running off the rolls at either end.
The gearing of our improved machine we arrange so that the bottom roll, C, is
the one which is driven, as in that way the endless band would always be in tension
on its downward passage between the rolls, and would loosen or become slack on
its upward course behind the rolls.
In practice we find it convenient sometimes to employ an auxiliary or guide
roll, G, for the purpose of holding up the slack of the endless band, D, as shewn
in Fig. 3. and in order to regulate this roller for the purpose of taking up the slack
of the said band, in the event of its stretching when in use, we fix the bearings
which carry the gudgeons of the said roller so that they may be actuated by a
spring, H. Sometimes instead of employing the flanges, I, on the top and bottom
rolls as shewn in Fig. 1, we employ guide rolls, I, fixed to the inside of the
framing as shewn in Fig. 3.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what.
we claim is:-
1. In a mangling, wringing, or like laundry machine, the employment of three
rollers in combination with an endless band in the manner and for the purposes sub-
stantially as herein described and illustrated.
