PROVISIONAL SPECIFICATION.
Improvements in Mangling and Wringing Machines.
We, JOHN WHITTAKER, HENRY WHITTAKER and WILLIAM WHITTAKER,
Wringing and Washing Machine Makers, all of Pioneer Works, Accrington in the
County of Lancaster, do hereby declare the nature of this invention to be as
follows :-
This invention relates to improvements in wringing and mangling machines, and
the object is to provide a ready means of varying the "nip" of the rollers making the
same greater or less as desired, and consists of links connected to the axis of the top
roller, and operated by means of spiral springs, and hand screws for depressing the
spring bar, or allowing the same to rise when the pressure on the springs is
removed, and by the use of such springs the liability of breakage of the spring bar
or screw rail is obviated and a more direct pressure or nip of the rollers is
obtained.
According to this our said invention on the axle of the top roller and at each
end of same we place a small block over which is passed a connecting link, and
the lower ends of these links, after passing through holes in the screw rail, which is
fixed to the end frames of the machine, are connected by nuts to each end of the
spring bar, which is free to rise and fall in slots or grooves in the end frames.
Passing through threaded holes in the screw rail are two hand screws, one at
each end, the lower ends of these screws rest on caps on the tops of spiral
springs.
When the pressure or nip of the rollers is to be made greater the hand screws
are turned, and the spiral springs are compressed and forced downwards pressing
down the spring bar, and by the connecting links drawing down the top roller, thus
increasing the nip. When the hand screws are turned in a reversed direction the
nip or pressure of the roller is lessened.
By the use of the two spiral springs in lieu of a bow spring as heretofore
employed, the pressure of the roller is more even, and direct, and strain and
breakage of the spring bar, and screw rail obviated.

Improvements in Mangling and Wringing Machines.
We, JOHN WHITTAKER, HENRY WHITTAKER and WILLIAM WHITTAKER,
Wringing and Washing Machine Makers, all of Pioneer Works, Accrington
in the County of Lancaster, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
This invention relates to improvements in wringing and mangling machines, and
the object is to provide a ready means of varying the "nip" of the rollers making
the same greater or less as desired, and consists of links connected to the axis of the
top roller, and operated by means of spiral springs, and handscrews for depressing
the spring bar, or allowing the same to rise when the pressure on the springs is
removed, and by the use of such springs the liability of breakage of the spring bar
or screw rail is obviated and a more direct pressure or nip of the rollers is
obtained.
According to this our said invention on the axle of the top roller and at each end
of same we place a small block over which is passed a connecting link, and the

page_text: lower ends of these links, after passing through holes in the screw rail, which is
fixed to the end frames of the machine, are connected by nuts to each end of the
spring bar, which is free to rise and fall in slots or grooves in the end frames.
Passing through threaded holes in the screw rail are two hand screws, one
at each end, the lower ends of these screws rest on caps on the tops. of spiral
springs.
When the pressure or nip of the rollers is to be made greater the hand screws
are turned, and the spiral springs are compressed and forced downwards pressing
down the spring bar, and by the connecting links drawing down the top roller, thus
increasing the nip. When the hand screws are turned in the reverse direction the
nip or pressure of the roller is lessened.
Such being the nature and object of our said invention the following is a
complete description of same, reference being had to the accompanying drawings
in which
Fig. 1 is a front elevation of a mangling or wringing machine having our
improvements applied thereto.
Fig. 2 is a view of the inside of one of the end frames of the machine shewing
clearly our improvements for varying the nip of the rollers.
Fig. 3 is a detail.
According to this our said invention on the axle 1 of the top roller 2 and at
each end of same we place a small block 3 formed of brass, gun or other metal
and constituting a cap or bearing above the axle 1 of the said top roller and over
the block 3 is passed a connecting link or links 4 preferably received in a groove
formed in the outer surface of the block or cap 3 and the lower ends 5.5 of these
links 4. 4 after passing through holes 6. 6 in the screw rail 7 which is fixed to the
end frames 8 of the machine, are connected by nuts 9 to each end of the spring
bar 10, which is free to rise and fall in slots or grooves 11 in the end frames 8.
Passing through threaded holes in the screw rail 7 are two hand screws 12. 12,
one at each end, of the said rail 7 the lower ends of these screws 12. 12 rest on
caps 13. 13 on the top of spiral springs 14. 14 which latter are maintained in
correct position by the pins or studs 15. 15 around which the springs are coiled the
said pins or studs 15. 15 being fixed to the spring bar 10.
When the pressure or nip of the rollers is to be made greater the hand
screws 12. 12 are turned, and the spiral springs 14. 14 are compressed and forced
downwards pressing down the spring bar 10 and by the connecting links 4. 4 acting
on the blocks 3. 3 thus drawing down the top roller 2 thereby increasing the nip.
When the hand screws 12. 12 are turned in the opposite direction the action is
reversed and the nip or pressure of the rollers 22" is lessened.
By the use of two spiral springs 14. 14 in lieu of a bow spring as heretofore
emlo yed, the pressure of the rollers is more even, and direct, and strain and
breakage of the spring bar and screw rail obviated.
It will be obvious that in lieu of the two links 4, 4 one only may be employed its
upper end terminating in a fork for attachment to the block 3.
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. The block or cap 3 links 4, sliding spring bar 10 springs 14, screw rail 7 and
hand screws 12, all in combination as and for the purpose herein described and
substantially as illustrated by the annexed drawings.
