PROVISIONAL SPECIFICATION.
Improvements appertaining to Pressure Regulating Mechanism for
Wringing and Mangling Machines.
We, RICHARD VARLEY, JOSEPH BUTTERFIELD, and JAMES SMITH, all of Cyclops
Works, Keighley, in the County of York, Machine Makers, do hereby declare
the nature of this invention to be as follows, that is to say:-
In connection with those wringing and mangling machines wherein laminated
springs are employed in connection with bars which reach from contact
with the pressure dies on
one side or end of the machine to those on
the other end thereof, it is well known that a great amount of friction is
generated when the said spring is being pressed against said bar or as said bar
is being moved against the pressure of said spring as is the case when some
bulky article is being dragged or passed between the rollers.
To obviate this and enable, the ends of the springs to freely travel or extend
over said bars during the performance of said operations is the object of this
invention and this is attained by forming said cross bar, either by making indenta-
tions therein or otherwise, so that they will receive antifriction rollers for the
ends of the springs to press upon. Appropriate projecting pieces being formed
on said bars to retain said rollers and springs in position.
The springs also have their outer ends bent or otherwise made so as to retain the
rollers in their desired positions when said rollers are arranged to roll over the
bar as the springs are being extended, while said formations of the springs are
not required when the rollers are arranged to rotate merely about their axes in
fixed bearings.
The said antifriction rollers may be one or more in number at each end of the
spring.
Instead of rollers being employed as above described, we may use antifriction
balls, by making the several parts in contact with which they roll to suit or
conform to them.

page_text: 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,
that is to say:-
In those wringing and mangling machines wherein laminated springs are
employed in connection with bars which reach from contact with the pressure
die's on one side or end of the machine to those on the other end thereof, it is well
known that a great amount of friction is generated when the said spring is being
pressed against said bar or as said bar is being moved against the pressure of
said spring as is the case when some bulky article is being dragged or passed
between the rollers.
To obviate this and enable the ends of the springs to freely travel or extend
over said bars during the performance of said operations is the object of this
invention which we attain as hereinafter described, and in order to enable it to
be readily understood, we have hereunto appended sheets of drawings illustrative
thereof, in which:-
Fig. 1 is a front elevation of a sufficient portion of a wringing or mangling
machine to illustrate the application thereto of our invention.
Fig. 2 is sectional end elevation of parts shown by Fig. 1.
Figs. 3, 4, 5, and 6 illustrate modifications of our invention as hereinafter
described.
We carry our invention into effect by forming the cross bars a either by making
indentations a¹ therein or otherwise so that they will receive antifriction
rollers b¹ for the ends c¹ c² of the springs c to press upon; appropriate projecting
pieces a² being formed on said bars a to retain said rollers and springs in position.
The springs e also have their outer ends c¹ bent as shown by Fig. 1 to retain
the rollers bb in their desired positions when said rollers are arranged to
roll over the bars a as the springs c are being extended, or one or more laminations
of the springs c may be bent so as to form journals for one or more of the rollers bbl
at each end thereof as illustrated by Fig. 3.
The rollers may if desired be mounted in fixed bearings d on the bars a
as shown by Fig. 4.
Instead of rollers being employed as above described we may use antifriction
balls e as shown by Figs. 5 and 6, in which case suitable furrows are formed
in the bars a to receive said balls and allow them to act as desired.
Instead of the bearings for the rollers 1 being formed integrally with the
springs as shown by Fig. 3 additional bearings intervening between said
rollers and said springs may be employed as will readily be understood.
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:-
1. In wringing and mangling machines, laminated springs, bars for trans-
mitting the pressure of said springs to the dies of the rollers, and, antifriction
rollers to work in connection therewith in combination substantially as specified.
2. In wringing and mangling machines, laminated springs, bars for trans-
mitting the pressure of such springs to the dies of the rollers and antifriction
balls to work in. connection therewith, in combination substantially as specified.
