Improvements in or Applicable to Wringing and Mangling
Machines.
I, GEORGE HENRY SLACK, of Clayton, near Manchester, in the County of Lancaster,
Spring Mattress Manufacturer, do hereby declare the nature of the said invention to
be as follows:-
My invention consists in a combination and arrangement or in combinations and
arrangements of mechanism, by which india rubber is applied in place of metal
springs or weights and levers, as an elastic medium through which the peripheries of
the two rollers of the wringing or mangling machine are pressed together with the
required pressure.
According to one modification of my invention a block of india rubber is used on
each side of the machine, the lower part of each block of india rubber rests upon or
against the upper side of the upper bearing (one on each side) for the upper roller,
and each block is enclosed within a box, or within plates, and the upper side of the
block of india rubber has a plate upon it acted upon by the end of a screw screwing
through a part from the framing (one screw on each side) and by this screw, pressure
is put upon the india rubber to force it against the bearing of the roller and thus give
pressure between the rollers, the elasticity of the india rubber allowing the roller to
rise and fall according to the thickness of the material passing between the rollers.
In place of one block of india rubber there is or may be an arrangement composed
of small pieces, discs or rings of india rubber with thin plates of metal between them
arranged in a box or otherwise.-In place of one screw on each side of the machine
there is or may be a shaft across the machine in suitable bearings on the side frames,
this shaft having excentrics to act upon the upper plate for compressing the india
rubber, and this shaft or may be oscillated by any suitable means.-Ör a sliding
bar with inclines is or may be used instead of the shaft with excentrics.

page_text: According to another modification of my invention, there is a cross bar or beam
between the two bearings of the upper roller, and to the middle of this cross bar or
beam a box is secured or formed thereon for an india rubber block or for a combina-
tion of india rubber discs or rings and metal plates, or other arrangements are used
instead of the box.-A screw screwing through a cross bar between the two side
frames and forming a part thereof acts upon the clastic arrangement in the said box,
or other arrangement so as to force down the bearings of the upper roller or lift them
and the roller when required.

1 GEORGE HENRY SLACK of Clayton, near Manchester, in the County of Lancaster,
Spring Mattress Manufacturer, 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 invention consists in a combination and arrangement or in combinations and
arrangements of mechanism, by which india rubber is applied in place of metal
springs, or weights and levers, as an elastic medium through which the peripheries of
the two rollers of the wringing or mangling machine are pressed together with the
required pressure.
According to one modification of my invention, a block of india rubber is used on
each side of the machine the lower part of each block of india rubber rests upon or
against the upper side of the upper bearing (one on each side) for the upper roller
and each block is enclosed within a box or within plates, and the upper side of the
block of india rubber has a plate or pusher upon it acted upon by the end of a screw
screwing through a part from the framing (one screw on each side) and by this screw
pressure is put upon the india rubber, to force it against the bearing of the roller
and thus give pressure between the rollers, the elasticity of the india rubber allowing
the roller to rise and fall according to the thickness of the material passing between
the rollers.
In place of one block of india rubber there is or may be an arrangement composed
of small picces, discs or rings of india rubber with their plates of metal between them
arranged in a box or otherwise-In place of one screw on each side of the machine
there is or may be a sliding bar with inclines, extending across the machine, the
inclines acting upon the pusher or plate to compress the india rubber.
According to another modification of my invention, there is a cross bar or beam.
between the two bearings of the upper roller, and to the middle of this cross bar or
beam a box is secured, or formed thereon, for an india rubber block or for a com-
bination of india rubber discs or rings and metal plates, or other arrangements are
used instead of the box-A screw screwing through a cross bar between the two side
frames and forming a part thereof acts upon the elastic arrangement in the said box or
other arrangement so as to force down both bearings of the upper roller as required.
Fig. 1 is a front elevation of so much of a wringing and mangling machine as wili
be necessary for illustrating my invention.
Fig. 2 is an end elevation at the driving end. a is the lower roller, a¹ is the upper
roller, these are arranged and geared in the ordinary manner.
The bearing for the upper roller a¹ is formed by preference of a hollow box & which
can slide up and down in the side frames c this hollow box has a piece of india

page_text: rubber & inserted in it as shown best by the section on an enlarged scale, fig. 3-The
piece of india rubber fills or nearly fills the interior of the hollow box which has a
block inserted in it to act and press upon the india rubber d within the box-To the
side frame c a bracket, c¹ is secured by bolts c² (see fig. 3) in which brackets c¹ a hole
is screw tapped for a hand screw e by which the block is forced into the box b to
compress the india rubber d within it to give the required pressure upon the shaft
of the upper roller a¹ to press it against the lower roller a.
There is a similar screw e and arrangement on each side of the machine.
f is a board extending across the machine.
Fig. 4, is a front elevation and fig. 5 an end elevation illustrating the mode of
carrying out my invention, by mechanism, applying pressure to compress the india
rubber on both sides of the machine simultaneously.
c are parts of the side frames,
is arranged to enter the hollow box
The end view of these blocks
view by fig. 8.
the two hollow boxes, the blocks each of which
as explained in reference to figs. 1 and 2.
is shown detached by fig. 7. and the top plan
made with a flange which has notches
The upper part of the block is
in it
to embrace and be guided by the inner sides of the slot in the end framing c for
the hollow box b.
These blocks have each an inclined groove 63 in them to correspond with an
incline g on a barg which extends between the two sides of the framing e of the
machine The end view of the bar g is shown detached by fig. 6.
The lower edge of the bracket csecured by bolts to the side frames c touches
the upper side of the bar and one bracket c¹ on one side also forms a bearing for
a shaft to rotate in which shaft has a collar on each side of the bearing in
the bracket e to prevent end movement in the shaft which is rotated by a hand
wheel on the outer end of the shaft.
The inner end of the shaft his screwed and screws through a projection g² from
the bar g.
It will be seen that by this screw h the bar g with inclines g¹ can be moved to and
fro simultaneously to compress more or less, as required, the india rubber in the
bearing box bon each side of the machine.
Fig. 9 is a front elevation illustrating another mode of applying pressure through
india rubber to the side bearings of the rollers a' on both sides of the machine at the
same time.
c side frames, a¹ upper roller, b× sliding bearings, ka beam or bar extending
between the sliding bearings b× in which bar a box or recess is formed for the
india rubber, which is pressed upon by a plate 2 which is acted upon by an adjusting
screw screwing through a cross bar c* secured to the side frames c.
The india rubber may be in each modification above described in one or more
pieces, or in rings dx or other forms, with plates d³, of metal between as illustrated
in figs. 9 and 10-The plates in this case are each supposed to have a central
projection to keep the ring d* in position but this projection d does not extend
from one plated so as to touch the adjoining plate, but leaves space between to
allow for compression in the ring of india rubber.
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.
1. The combination of one or more pieces of india rubber arranged by preference
in a box to be acted upon by compression substantially as and for the purpose
hereinbefore described.
2. The combination and arrangement of india rubber in hollow bearing boxes
with blocks and screws for compressing the india rubber substantially as and for
the purpose herein before described and illustrated by figs. 1 and 2 of the drawings.
3. The combination and arrangement of india rubber with mechanism for simul-
taneously acting upon the bearings on both sides of the machine-substantially as and

page_text: for the purpose hereinbefore described and illustrated by figs. 4, 5, 6, 7 and 8 of the
drawings.
4. The combination and arrangement of mechanism for putting pressure upon the
bearings on both sides of the machine at the same time through india rubber sub-
stantially as and for the purpose herein before described and illustrated by figs. 9
and 10 of the drawings."
5. The application of india rubber in pieces of the ring or other suitable form
with plates of metal interposed substantially as and for the purpose hereinbefore
described and illustrated by figs. 9 and 10.
