Improvements in Wringing and Mangling Machines.
We, RICHARD VARLEY and JOHN PROCTER WOLFENDEN both 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 :-
It relates to the application of means to wringing and mangling machines
whereby the rollers of these machines may be raised from contact with each
other for well known purposes when same are not in use, and our said invention
consists of arranging and constructing said means in such a manner that while
they are enabled to perform their functions efficiently yet they may be cheaply
produced.
In carrying our invention into effect we mount upon one or other of the rollers'
shafts two eccentrics or cams, one at one end one at the other end of said roller.
These cams are so fixed on said shafts that they revolve with them.
On the end frame or other framework of the machine are mounted sliding pieces
which may be moved into the path of motion of the cams as and when desired.
When these sliding pieces are thus moved into the path of motion of the cams, on
the handle of the machine being turned in order to cause the rollers to revolve as
usual, when the cam surfaces come into contact with the sliding pieces their actions
thereon effect the desired movement of the rollers, such movement, provided the
cams are on the upper roller's shaft, is effected by same being bodily raised from
the then stationary sliding pieces, while provided the cams are upon the lower
roller's shaft then both the sliding pieces and the upper roller are raised.
In order that the user may see when the rollers have been separated without
having to carefully examine the positions of same, an indicating mark is made on
one or other of these rollers to show when it has reached the desired position.
Dated this 10th day of April 1895.

Improvements in Wringing and Mangling Machines.
We, RICHARD VARLEY and JOHN PROCTER WOLFENDEN both of Cyclops
Works, Keighley in the County of York, Machine Makers, 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, that
is to say:
It relates to the application of means to wringing and mangling machines
whereby the rollers of these machines may be raised from contact with each
other for well known purposes when same are not in use, and our said invention
consists of arranging and constructing said means in such a manner that while they
are enabled to perform their functions efficiently yet they may be cheaply
produced.

page_text: In order that our said invention may be readily understood we will proceed to
describe same by reference to the accompanying sheet of drawings which are
illustrative thereof;―
Fig. 1 being front elevation and Fig. 2 end elevation of a sufficient portion of a
wringing or mangling machine to show the application of our invention.
Fig. 3 part sectional end elevation enlarged scale of certain of the parts shown
by Figs. 1 and 2.
Fig. 4 is front elevation of the parts shown by Fig. 3, the framework and a
portion of our improved device being shown in section.
In carrying our invention into effect we mount upon the shaft of the roller a
or upon the shaft c of the roller d (but preferably the former for the reason
hereinafter explained), two eccentrics or cams ff' one being at one end of the
roller while the other is at its other end. These cams ff are fixed in any
convenient manner so that they will revolve with the roller and shaft which
-carries them.
On the end frames (or other suitable part of the framework) g g₁ of the machine
we mount sliding pieces which may be moved into the path of motion of the
cams ffas and when desired, these pieces ¹ being shown as being mounted upon
projections kk' formed integrally with the framework g g although other well
known mechanical devices may be employed for this purpose.
.
When the sliding pieces are moved so that their upper surfaces are brought
into the path of motion of their cams ff' as is shown by Fig. 3, on the handle of
the machine being turned in order to cause the rollers to revolve as usual, when
-the cam surfaces come into contact with the upper surfaces their actions thereon
effect the desired movement of the roller a which movement as is shown is in a
vertical direction to raise the said roller a clear of the roller d. The same result
of raising the roller a clear of the roller d, might be attained by mounting the
cams upon the shaft of the said roller d and arranging the sliding pieces h
to intervene between same and the shaft 6 in which case both the pieces and
the roller a would have to be bodily litted while the cost of production in this
latter case would exceed that of the former hence we preferably make use of said
former arrangement.
In order that the user may see when the rollers have been separated without
having to carefully examine the positions of same, an indicating mark, as that at s,
is made on the roller a while another mark t is made on the framework so that
when one is brought opposite the other the position desired has been reached.
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
1. In a wringing and mangling machine the combination of the several parts
arranged as described for effecting the separation of the rollers substantially as
.set forth.
•
2. In wringing and mangling machines the combination of cam and slide devices
for imparting.vertical movements to the rollers of said machines substantially as
-specified.
