IMPROVEMENTS IN SPRINGS FOR MACHINES FOR WASHING, WRINGING, AND MANGLING FABRICS
Year: 1884

page_text: We, JONATHAN BARNES and RICHARD WALTON KENYON, both of Accrington in
the county of Lancaster, Ironfounders and Machinists do hereby declare the nature
of the said invention for "IMPROVEMENTS IN SPRINGS FOR MACHINES FOR WASHING,
WRINGING, AND MANGLING FABRICS "to be as follows:-
C
Plate springs at present in use for machines for washing, mangling, and wringing
fabrics are formed either in a single span, their ends bearing on the journals of the
rollers and the adjustment of their compression controlled by a screw pressing on
them from the opposite side, or are formed in a continuous length of a series of
curves, the ends of the spring resting on the journals of the rollers, and the plates
of the intermediate curves on the side of the spring furthest from the rollers
pressing against the cross bar, which receives the pressure in one direction, the
pressure being regulated by a screw drawing the centre spring towards the
crossbar.
г
:
Our invention is designed as an improvement on this latter, and consists of two
springs so placed that one end of each spring will press on a journal of the roller,
and the other end of each will rest on a casting supported on the head of, a screw
passed through the top rail or crossbar. The plates of these springs, in which form
they are preferably made are held in position by a clip passing round their centres.
A pin is riveted to the centre of each spring and projecting upwards passes through
a hole made in the top. rail. The hole in the rail is sufficiently large to allow of
some play for the movement of the spring. These pins keep the springs in position.
The pressure is regulated by raising or lowering the screw; as the ends of the
springs resting on the aforesaid casting are drawn towards the crossbar the pressure
is increased, and is decreased when they recede from it.
If found desirable or more convenient two screws may be employed one for each
spring, but we prefer only to use one, as the pressure on each end of the roller is
then more likely always to remain equal.

We JONATHAN BARNES and RICHARD WALTON KENYON, Accrington, Lancashire,
Ironfounders and Machinists do hereby declare the nature of our said invention for
IMPROVEMENTS IN SPRINGS FOR MACHINES FOR WASHING 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:-
Plate springs at present in use for machines for washing mangling and wringing
fabrics, in which calendering or squeezing rollers are employed, are formed either
in a single span, their ends bearing on the journals of the rollers and the adjust-
ment of their compression controlled by a screw pressing on them from the opposite
side, or are formed in a continuous length of a series of curves, the ends of the
spring resting on the journals of the rollers, and the plates of the intermediate
eurves on the side of the spring furthest from the rollers pressing against the
crossbar, which receives the pressure in one direction, the pressure being regulated
by a screw drawing the centre spring towards the crossbar.
Referring to the annexed drawing:
Our invention is designed as an improvement on this latter, and consists in
providing two springs A B, so placed that the outer end a and b of each spring will
press on the journal c c¹ respectively of the roller C, and the other or inner end
a b of each will rest on a casting or block D supported on the head e of a screw E
passed through the top rail or crossbar F. The plates a¹¹ 611 of the springs A. B,
in which form they are preferably made, are held in position by a clip G passing
round their centres. A pin g is riveted to the centre of each clip, retaining the
spring, and projects upwards through a hole in the enlargement f made on the top
rail. The hole in the rail is sufficiently large to allow of some play for the move-
ment of the spring. These clips and pins keep the springs in position. The
pressure is regulated and adjusted by raising or lowering the screw E by means of
the hand wheel E¹. As the ends a b¹ of the springs A B resting on the casting D
are drawn towards the crossbar F, the pressure is increased, and is decreased when
they recede from it.
If found desirable or more convenient, two screws may be employed one for each
spring, but we prefer only to use one, as the pressure on each end of the roller is
then more likely always to remain equal.
We do not limit the invention to the exact details shown, as it might be modified
by making a fixed supporting block instead of the adjustable block D, and by
regulating or adjusting the pressure by screws acting on the centre of the springs,
but we prefer the method shown. The springs might in some instances be applied
to the bottom.roller instead of the top one.
Having now particularly described and ascertained the nature of the said
Invention, and in what. manner the same is to be performed, we declare that what
we claim is :-
In machines for washing wringing or mangling fabrics, in which callendering or
squeezing rollers are employed, the use of two springs having a supporting block
for their inner ends, and the outer ends of each resting on the journals of- one
roller, substantially as described and shown.
