Improvements in Wringing and Mangling Machines.
We, WILLIAM DORE, of 1 Waugh Street, Russell Street Beswick, Manchester,
in the County of Lancaster, Sewing Machine Repairer, JOHN PITT TAPLEY,
of 90 Hutton Street, Salford, in the said County, Engineer, and JOHN HARRY
PARR of the firm of Railton and Company, of 24 London Road, Manchester afore
said, Manufacturers of Ladies' Underclothing do hereby declare the nature of this
invention to be as follows:-
Our invention relates to improvements in wringing and mangling machines and
the chief object of our improvements is to overcome the defects of the present
system of weighting the top roller in such machines by the direct action of weights
or springs.
In carrying our improvements into effect we propose to employ three rollers
instead of only two as hitherto customary and we fix preferably upon the axis of
the bottom roller two chain wheels one near each end from which chains pass to a
pair of chain wheels loose upon the axis of the top roller. On the side of each
top chain wheel we form two lugs through which passes a screw which also passes
freely through an arm the boss of which is fixed upon the axis of the top roller;
on this screw is a coiled spring which is compressed between the aforesaid arm and
a cap upon the screw; by turning the screws the position of the caps can be
adjusted and the springs be more or less compressed. The chains which pass
over the chain wheels are so guided by means of studs or equivalents that while
geared up as tightly as possible upon one side they are very slack upon the other
and one chain is tight upon the side upon which the other is slack.
In operation when clothes or fabrics are inserted between the top and inter-
mediate rollers and the ordinary handle is turned to rotate the rollers, the chains
drive the top roller and the springs yield sufficiently to permit the passage of
the clothes; but at the same time put a heavy although smooth pressure upon
them.

COMPLETE SPECIFICATION.
Improvements in Wringing and Mangling Machines.
We, WILLIAM DORE, of 1 Waugh Street, Russell Street, Beswick, Manchester,
in the County of Lancaster, Sewing Machine Repairer, JOHN PITT TAPLEY, of
90 Hulton Street, Salford, in the said County, Engineer, and JOHN HARRY
PARR, of the firm of Railton and Company, of 24 London Road, Manchester
aforesaid, Manufacturers of Ladies' Underclothing, 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 :-
Our invention relates. to improvements in wringing and mangling machines and
the chief object of our improvements is to overcome the defects of the present
system of weighting the top roller in such machines by the direct action of weights
or springs.
In carrying our improvements into effect we propose to employ three rollers
instead of only two as hitherto customary and we fix preferably upon the axis of
the bottom roller two chain wheels one near each end from which chains pass to a

page_text: pair of chain wheels loose upon the axis of the top roller. On the side of each top
chain wheel we form two lungs through which passes a screw which also passes
freely through an arm the boss of which is fixed upon the axis of the top roller; on
this screw is a coiled spring which is compressed between the aforesaid arm and a
cap upon the screw; by turning the screws the position of the caps can be adjusted
and the springs be more or less compressed. The chains which pass over the
chain wheels are so guided by means of studs or equivalents that while geared up
as tightly as possible upon one side they are very slack upon the other and one
chain is tight upon the side upon which the other is slack.
And in order that our invention may be fully understood and readily carried
into effect we will describe the accompanying sheet of drawings reference being had
to the figures and letters marked thereon.
Figure 1 is a front elevation and Figs. 2 and 3 are end elevations, partly sections
of our improved wringing and mangling machine.
In these views the three rollers which we employ are designated a b c
respectively and are supported in the machine frame d, the two upper rollers b c
being free to move vertically hut not end wise in open bearings. On the axis a¹ of
the bottom roller a is mounted loosely a hand wheel in the case of small or
domestic machines; but for large machines a pair of fast and loose pulleys, friction
gearing or other suitable means for receiving and transmitting motive power may
be employed. Formed with or secured to the hand wheel e is a pinion e' gearing
with a spur wheel which is formed with or has secured to it a pinion f¹ both
being mounted on a stud y secured to the frame d. The pinion fl gears with a
spur wheel h fixed on the axis a¹ of the bottom roller a and combined with the
spur wheel or separately fixed upon the axis a' is a chain wheel i which drives by
a chain; a second chain wheel k mounted loosely upon the axis c¹ of the top
roller c.
Upon the side face of the chain wheel k are formed two ears or lugs / through
which passes freely a thumb screw m which also passes freely through an arm n,
the boss 'n' of which is keyed upon the axis c'.
On the thumb screw m is coiled a
spring o which is compressed between the arm n and a cap or collar p which is
threaded on the screw m and is made with a flat sided head or is kept from turning
in any other convenient manner, so that by turning the thumb screw m the position
of the cap p can be adjusted and the tension of the spring o regulated as required.
The chain (which for the sake of clearness is not shown in Fig. 1) passes over
the chain wheels i and k and is guided tightly in gear by a tension roller q mounted
on an elbow lever r fulcrumed on the axis a and having at the other end a weight s
which bears normally upon a projection d¹ on the frame d.
The above specified arrangement of chains and chain wheels is duplicated upon
the other end of the rollers by the chain wheel ", chain j, chain wheel k', ears or
lugs, thumb screw m², arm n², boss n³, spring o³, cap or collar p', tension roller g',
lever and weight s', all of which are mounted arranged and operate in the manner
described with reference to the parts bearing corresponding letters at the other end
of the rollers. The chains jjare so guided by the tension rollers q g' that while
geared up tightly upon one side they are left slack upon the other and the chain j
is slack upon the side upon which the chain is tight.
In operation when clothes or fabrics are inserted between the top roller c and
intermediate roller b and the axis a' is turned either by the ordinary handle or by
power as the case may be in order to rotate the rollers, the chains drive the top
roller o through the springs o o' and arms n n and the said springs yield and the
tension rollers qq move outward sufficiently to permit the roller c to rise in its
open bearings and the clothes or fabrics to pass freely and easily between the
rollers bc; but at the same time a heavy although smooth pressure is put upon
them.
In this manner and by this combined arrangement of chain wheels with chains
slack upon one side and tightly geared upon the other in conjunction with the
adjustable spring connection between the chain wheel and the top roller we are

page_text: enabled to weight the rollers to any extent desired and this without putting undue
friction on the bearings of the rollers as is the case in all other arrangements for
weighting the rollers with which we are acquainted.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
In a wringing or mangling machine :-
1. The combination with a nest of three rollers of which the bottom roller is
driven by hand or power, of an arrangement of chains and wheels for transmitting
motion from the aforesaid driven roller and communicating it through a spring
connection to the top roller substantially in the manner and for the purposes herein
set forth.
2. The general arrangement and combination of parts embodying our improve-
ments substantially as and for the purposes herein described and as illustrated by
the accompanying drawings.
