Improvements in Wringing and Mangling Machinery.
I THOMAS WALKER of 9 Regent Street Eccles in the County of Lancaster,
Machinist, do hereby declare the nature of this invention to be as follows:-
This invention relates specially to apparatus used for wringing water or fluid
from clothes or fabrics the object being to increase the durability of the apparatus.
It is known to persons. conversant with such machines that the bottom roller
becomes worn more quickly than the upper roller, and my invention consists mainly
in mounting the said rollers in a reversible frame, carrying gearing, by which
means either roller may be set in the lower position and become the driving roller
without dismounting the said rollers from their bearings.
For this purpose instead of mounting the bearings of the rollers in the main
frame of the machine I mount them upon a separate frame or frames capable of
swivelling upon centres at either side of the machine, the centres being mid-way
between the axial' lines of the top and bottom roller, and instead of mounting the
axle of one roller in fixed bearings as usual I mount both rollers in sliding blocks.
Each block is provided with a spindle or shank passing through a spiral spring
held in place by a second sliding block.
The sliding block at either end of the axle of the roller which is set uppermost
is pressed down by an adjusting screw working through the fixed'top'rail of the
apparatus and made hollow or tubular to allow it to pass over the spindle or shank
of the bearing the said screw passing through the end of the pivotted or swivelling
frame and locking 'the same in position. The lower end of the said frame is
situated immediately above a flat bracket or plate fixed to the frame which
'supports' the corresponding spindles of the axle block of the lower roller.
The rollers are geared together by toothed wheels at one end inside the
swivelling frame or frames, and' (preferably at the other end) are each provided
with a pinion between the fixed and swivelling frames, which is brought when its
corresponding roller is the lower one, into gear with a driving pinion revolving on
a short shaft or stud mounted in the main' or fixed frame of the machine and driven
by suitable gearing by hand or other motive power.
The flat brackets (or 'plate) as above described support the axles of the lower
roller so that its pinion will gear properly with the main driving pinion. I may
provide a bolt or other device for locking the bottom of the swivelling frame or
frames as well as the top thereof.
It will be seen that by unscrewing the adjusting screws above named until they
are free of the swivelling frame or frames (and releasing the bottom locking
device if used), the position of the rollers may be reversed by simply turning the
frame or frames on its (or their) axes, and that by so reversing the said rollers
from time to time the wearing of one before the other will be avoided; and the
machine will last longer without repairs, and will work more evenly than if a new
bottom'roller were applied to an old top roller.
It is evident that this invention is applicable to wringing apparatus used
separately or in combination with washing or other machines.

Improvements in Wringing and Mangling Machinery.
I THOMAS WALKER of 9 Regent Street Eccles in the County of Lancaster,
Machinist, 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 :-
This invention relates specially to apparatus used for wringing water or fluid
from clothes or fabrics, the object being to increase the durability of the
apparatus.
It is well known to persons conversant with such machines that the bottom roller
becomes worn more quickly than the upper roller, and my invention consists mainly
in mounting the said rollers in a reversing frame carrying gearing, by which means
either roller may be set in the lower position without dismounting the said rollers
or otherwise disturbing their bearings.
The nature of my said invention and the manner in which the same is to be or
may be performed or carried into practical effect will be readily understood on
reference to the sheet of drawings hereunto annexed and the following explanation
thereof.
Fig. 1 on the annexed drawing shows a front elevation of so much of a wringing
or mangling machine as is requisite to illustrate the application of my invention
thereto.
Fig. 2 is an end view (partly in section) of the reversing frame, and Fig. 3 a
vertical section taken through about the centre of the machine.
For the purposes of my invention instead of mounting the bearings of the rollers a
and a' in the main frame b of the machine I mount them upon a separate frame or
frames c capable of swivelling upon centres d at either side of the machine, the
centres being mid-way between the axial lines of the top and bottom roller, and
instead of mounting the axle of one roller in fixed bearings as usual I mount both
rollers in sliding blocks e see Fig. 2. Each block e is provided with a spindle or
shank passing through a spiral spring g held in place by a second sliding
block h.
The sliding block e at either end of the axle of the roller a which is set
uppermost is pressed down by an adjusting screw i working through the fixed top
rail of the apparatus or machine and made hollow or tubular to allow it to pass
over the spindle or shank of the bearing the said screw passing through the end
of the pivotted reversing or swivelling frame c and locking the same in position.
The lower end of the said frame is situated immediately above a flat bracket or
plate 6x, fixed to the frame, which supports the corresponding spindles f of the axle
block of the lower roller a¹.
The rollers a and a' are geared together by toothed wheels k at one end inside
the swivelling frame or frames c and (preferably at the other end) are each
provided with a pinion between the fixed frame b and swivelling frame c which is
brought, when its corresponding roller is the lower one, into gear with a driving
pinion m revolving on a short shaft or stud n mounted in the main or fixed
frame of the machine and driven by suitable gearing by hand or other motive
power.
The flat brackets (or plate) 6x as above described support the axles of the lower
roller a¹ so that its pinion will gear properly with the main driving pinion m.
I prefer to provide a bolt or pin o or other device for locking the bottom of the
swivelling frame or frames c as well as the top thereof.
It will be seen that by unscrewing the adjusting screws i above named until they
are free of the swivelling frame or frames c (and releasing the bottom locking
device g), the position of the rollers a and a' may be reversed by simply turning the
frame or frames c on its (or their) axes, and that by so reversing the said rollers a

the machine will last longer without repairs, and will work more evenly than if a
new bottom roller were applied to an old top roller.
It is evident that this invention is applicable to wringing and mangling apparatus
used separately or in combination with washing or other machines.
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 :-
:-
Mounting the rollers of a wringing or mangling machine in a reversing or
swivelling frame or frames so arranged upon pivots that the position of the two
rollers can be reversed without dismounting the said rollers or otherwise disturbing
their bearings substantially as herein before described and illustrated by the
drawings annexed.
