WILLIAM HUTCHINSON Boot & Shoe Dealer 145 Briggate Leeds do hereby
declare the nature of this invention to be as follows:-
Hitherto the person useing a wringing machine is obliged to place the fingers in
such dangerous proximity to the rollers that there are frequent accidents on this
account. I claim that my invention prevents the possibility of such an accident.
The method I adopt is to suitably fix an additional roller the same length, but
much less in diameter than the ordinary rollers, this third roller rests upon the
bottom roller, but in front, and will (when the machine is worked) revolve and
convey to the two principal rollers the article that requires to be wrung or pressed
without the operators fingers being in any danger.
I further claim that my additional roller enables the machine to execute its work
more satisfactory, partly caused by the additional pressure, and partly owing to the
extra stretching which is effected in consequence of the third roller being less in
diameter than the two back rollers, on this account it holds the article which is
being wrung or pressed back, so that it enters the large rollers in a more even,
tighter, 'and straighter condition.

1 WILLIAM HUTCHINSON of 145 Briggate Leeds in the County of York Boot
and Shoe Dealer, 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 :-
The object of my invention is to prevent such accidents as now frequently occur
with wringing and like machines as at present used, owing to the necessity of
bringing the attendant's fingers into dangerous proximity to the rollers when
putting work into the machine.
My invention consists in providing an additional roller of the same length but
much less in diameter than the ordinary rollers. This third roller is mounted
(preferably so as to rest upon the bottom roller) in front, and so arranged as to
revolve only and entirely by friction between it and one of the other rollers,
preferably the bottom one."
This third roller when the machine is being worked revolves by friction, and
conveys to the principal rollers the article required to be rolled or pressed, and as
it covers the opening in front of the line of contact of the two principal rollers,
there is no danger of the attendant's fingers being thereby caught and injured.
This third roller is carried in bearings capable of slight movement radially with
respect to the main roller against which this third roller rests. The pressure
between these rollers may be due entirely to the weight of the third roller, or to
springs, or weights acting against its bearings. The bearings may be carried in
ordinary slot guides, or formed in the free ends of a pair of levers, hinged about
the axis of the top roller; and to which ends the aforementioned springs or weights
may be attached.

page_text: These my improvements moreover enable the machine to perform the work
more satisfactorily, and the work can be got through in less time, since the third
roller feeds the work more evenly and uniformly, and the attendant does not
require to exercise so much care (and consequently takes less time) to enter the
work into the machine. This third roller also acts as a preliminary strainer, much
of the water being by it pressed out of the clothes, and the main rollers do not get
so damp and last longer.
And in order that my invention and the manner in which the same is to be per-
formed, may be more readily and clearly understood reference is given to the
accompanying sheet of drawings in which
Fig. 1 is a perspective view of a wringing machine with my improvements
applied thereto.
Fig. 2 is a part sectional elevation in which the third roller bearings are formed
in the three ends of a pair of hinged levers, and
Fig. 3 is a part sectional elevation in which the third roller bearings are fitted in
slot guides.
In all the figs. the same reference letters refer to the same or corresponding part.
a a is the frame casting of the machine.
bis the ordinary top roller, and
c is the ordinary bottom roller.
d is the third roller.
e Figs. 1 and 2 are the hinged levers, having the bearings of the third roller
formed in their free ends and hinged to the axis of the top roller, between the
roller ends and the frame casting. The bearings for the hinged end are convéniently
formed as fork slots, so that the levers can be placed in position without taking the
top roller out of the machine. The free ends of these hinged levers are shewn pulled
downwards by the spiral springs f, though elastic rubber bands or weights (or even
flat springs as shewn in dotted lines) may be used.
In Fig. 3 the bearing for one end of the third roller is shewn fitted in the slot
guide g, and pressed by the spiral spring f
The levers e (see Fig. 2) may be hinged to studs or pins nttached to the side
frames a, and if preferred kept pressed against the top roller by springs or levers
and weights, but such arrangement is not generally convenient.
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:-
1st. In wringing, mangling, and other similar machines, the use of a third roller
carried in moveable bearings and rotated only and entirely by friction between it
and one of the ordinary rollers (or interposed clothes).
2nd. In wringing, mangling and other similar machines, the arrangement of a
third roller carried in bearings in the free ends of a pair of hinged levers and
pressed against one of the ordinary rollers by its own weight or by springs or by
.weights substantially as herein set forth.
3rd. In wringing, mangling and other similar machines, the device of a third
roller carried in moveable slot bearings and pressed against one of the ordinary
rollers by its own weight or by springs or by weights substantially as herein
set forth.
