SPECIFICATION.
Improvements in Washing, Wringing, and Mangling Machines.
I THOMAS BRADFORD of the Crescent Iron Works, Salford in the County of
Lancaster, Engineer do hereby declare the nature of this invention to be as
follows:-
My improvements relate to the means of obtaining pressure upon rollers for the
purpose of wringing or expressing water from household or other linen and consists
of a novel combination of spiral spring and lever with fulcrum, such lever to be made
of round or square steel of suitable diameter; the fulcrum end of the lever may be
secured in the ordinary manner, and as adopted by me for some years past, but
instead of hanging a weight upon the end of the lever to obtain the
pressure required,
1 adopt a spiral steel spring of suitable power, and this spiral place over the
regulating bolt, that is, the regulating bolt passes through the spring which fits into
a bottom and top socket; the flanged plate of the bottom socket rests upon the end
of the lever furthest from its fulcrum which is bent or returned round a sufficient
length and width to clip the connecting bolt. This bending or returning is elongated
so as to form a treadle for the foot or bearing for the knee, but preferably for the
foot, in wringing and mangling machines with wood rollers, and for the hand for
combined washing machines with india rubber rollers.
By these means the spiral spring can be depressed. or closed so as to exercise the
pressure required, which can be regulated as desired by a series of slots holes, or
notches cut into the connecting bolt into which a set screw enters, the said screw
passing through the upper spring socket previously referred. to; and so the spring is
secured at either its minimum or maximum pressure or at intervening points.
This combination of spring and lever may be applied to washing machines with.
wringing or mangling rollers either when the said combined spring and lever pressure
is used above or below the wringing or mangling rollers and more especially to a
machine known as the "Tudor Vowel" washing machine; or it may be applied to
machines used exclusively for wringing and mangling.

COMPLETE SPECIFICATION.
Improvements in Washing, Wringing, and Mangling Machines.
I THOMAS BRADFORD of the Crescent Iron Works, Salford in the County of
Lancaster Engineer 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:
My improvements relate to the means of obtaining pressure upon rollers for the
purpose of wringing or expressing water from household or other linen, and consists
of a novel combination of apparatus for applying and removing at pleasure the
pressure of spiral springs for this purpose.
The nature of my invention and the manner in which the same is to be performed
or carried into practical effect will be readily understood on reference to the sheet of
drawings hereunto annexed and the following explanation thereof. Fig. 1. on the
drawings is an end elevation and Fig. 2. a front view of a wringing machine with
my improvements shown as applied thereto. a being the framing, b the rollers, c the
levers, and d the spiral springs.

page_text: The levers c may be made of round or other steel or iron of suitable diameter or
thickness, and the fulcrum end thereof may be secured in the ordinary manner, but
instead of hanging a weight upon the free end of the same to obtain the pressure
required I adopt a spiral spring d of suitable power and this spring I place over the
regulating bolt e, that is, the said bolt passes through the spring which fits in a
bottom socket and a top socket g; the flanged plate of the bottom socket f rests
upon the end of the lever c furthest from its fulcrum, which end is bent round or
returned (as shown at c* on the detached plan view Fig. 3) so as to clip the regulating
bolt e.
This bent or returned portion is made of sufficient length to form a treadle
for the foot or a bearing for the knee (but preferably the former) in wringing and
mangling machines with wooden rollers, or for the hand in combined washing machines
with india rubber covered rollers.
с
By these means the spiral springs d can be depressed or closed so as to exercise
the pressure required, which can be regulated as desired, by a series of holes (as
shown at Fig. 1) or by slots or notches cut into the regulating bolt e into which a set
screw or pin enters, passing through the upper spring socket g'and thus the spring is
secured at either its minimum or maximum pressure, or at intervening points.
At Fig. 2 the top flange of the upper socket 9 is shown as provided with notches
or steps upon either of which the catch g* may be placed for the same purpose.
This combination of springs and lever may be applied to washing machines with
wringing or mangling rollers, either when the said combined spring and lever pressure
is used above or below the wringing or mangling rollers and more especially to the
form of machine known as the "Tudor Vowel" washing machine, or it may be
applied to machines used exclusively for wringing and mangling as illustrated by the
drawings.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed I declare that what I
claim is :-
The novel combination of springs and levers, substantially as hereinbefore described
and illustrated by the drawings annexed for obtaining pressure upon the rollers of
washing wringing and mangling machines.
