Improvements in Wringing and Mangling Machines, and in other
Machines having Rollers working in a similar manner.
1, JOHN BURLINSON of 32 Argyle Square Sunderland in the County of
Durham Engineer do hereby declare the nature of this invention to be as
follows
My invention relates to wringing and mangling machines and other machines
having rollers working in a similar manner that is to say running in contrary
directions. Hitherto such rollers have been geared direct by means of tooth wheels
having teeth of such a depth or length as to permit the upper roller to rise some
distance without the gearing becoming disengaged. But such teeth are unavoidably
of defective design thus necessitating frequent renewals of the wheels while the
extent of rise or the opening between the rollers is limited or insufficient involving
the risk of frequent breakages.
By my arrangement of gearing the wheels are at all times in full gear no matter
what the extent of opening between the rollers may be.
One of the rollers by preference the lower one is as heretofore usual in mangling
and wringing machines arranged with fixed bearings and the other or upper roller
in movable bearings so as to be free to rise to the required extent. The rise is
however not quite vertical as heretofore but so that the upper roller describes an
arc of a circle. On the one end of the spindle of each roller I fix a toothed wheel
of a size smaller than the roller; these wheels I connect by two intermediate
wheels by preference of smaller diameter which have their gudgeons fixed laterally
in the machine framing. The bearings of the upper roller are arranged in a pair
of double armed levers one at each end of the machine these levers having the
fulcrum at one end while the other end is connected to a helical or other spring.
The helical springs may suitably be coiled round two out of four tubular standards
forming part of the framing and having their lower ends acting on cotters connected
to rods in the standards the upper ends of said rods being jointed to the levers.
For a cross connection or stay between the tubular standards prefer to use the
tray or hopper for catching the water from the rollers making it of cast iron with
suitable lugs for fastening to the frame at each end. The receptacle underneath
the hopper may suitably rest on a lower stay or cross connection for the framing
which latter may be provided with wheels or castors for easy removal from place
to place. Instead of the toothed wheel gear described and which I prefer may
use friction wheels, or sprocket wheel and chain connection or other suitable gearing
arranged laterally to the rollers.
In a modified arrangement of gearing 1 fix on one end of the upper roller spindle
and on the opposite end of the lower roller spindle a large tooth wheel. These
gear each into a laterally arranged intermediate pinion running on fixed gudgeon
and these pinions again gear into pinions on what I may call a first motion shaft
having its bearings in the two end frames.

Improvements in Wringing and Mangling Machines, and in other
Machines having Rollers working in a similar manner.
1, JOHN BURLINSON of 32 Argyle Square Sunderland in the County of Durhamı
Engineer, 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 relates to wringing and mangling machines and other machines
having rollers working in a similar manner that is to say running in contrary
directions. Hitherto such rollers have been geared direct by means of tooth
wheels having teeth of such a depth or length as to permit the upper roller to rise
some distance without the gearing becoming disengaged. But such teeth are
unavoidably of defective design thus necessitating frequent renewals of the wheels
while the extent of rise or the opening between the rollers is limited or insufficient
involving the risk of frequent breakages. By my arrangement of gearing the
wheels are at all times in full gear no matter what the extent of opening between
the rollers may be.
My invention also comprises improvements in the construction of the mangling
machine framing.
Figure 1 of the accompanying drawings is a side view of a mangling machine
constructed according to my invention.
Figure 2 is an end view partly in section,
Figure 3 an end view seen from the opposite end and Figure 4 is a plan.
One of the rollers by preference the lower one A is as heretofore usual in
mangling and wringing machines arranged with fixed bearings forming part of the
framing B and the other or upper roller C in movable bearings D so as to be free
to rise to the required extent. The rise is however not quite vertical as heretofore
but so that the upper roller C describes an arc of a circle. On the one end of the
spindle of each roller I fix a toothed wheel E and F respectively which are of a
size smaller than the roller; these wheels E and F I connect by two intermediate
wheels G and H by preference of smaller diameter as here shown which have their
gudgeons G and D₁ fixed laterally in the machine framing part B. The bearings
of the upper roller are arranged in a pair of levers Done at each end of the
machine these levers having the fulcrum at one end at D₁ in the framing part B
while the other end is connected to a helical or other spring. The helical springs I
may suitably as here shewn be coiled round the two tubular standards B forming
part of the framing and having their lower ends acting on cotters K' connected to
rods in the standards the upper ends of said rods being jointed to the levers.
is
The tubular standards B and 132 at each end carry at their upper ends the
part B forming the bearings for the lower roller A. The helical spring I coiled
round the upper part of each tubular standard B rests below on a sleeve B³ which
can slide on the said standard and by the cotter K is united to the inner rod K the
upper end of which is jointed to the outer end of the aforesaid lever D forming
bearing for the gudgeon of the upper roller C. The socket B₁ enclosing the
spring and in which the sleeve B can work up and down is by the nuts B° B
united to the frame part B2. When therefore the roller Crises the spring
compressed. The cotter K' works in slots in the tube frame B². It will thus be
understood that while the upper roller C can rise as required against the increasing
resistance of the springs I it describes an arc struck from the axis of the
gudgeons D' and that the intermediate tooth pinions H. and G are in full and
efficient gear all the time with the wheels and E. L is a fly wheel with
handle L. This fly wheel carries a pinion M working on a fixed stud and gearing
with a tooth wheel N which is in one with the pinion G.

page_text: For a cross connection or stay between the tubular standards B₁ B¹ B² B²
I prefer to use the tray B* or hopper which is adapted to catch the water
directly from under the middle of the rollers instead of as heretofore usual coming
right in front where it is in the way. And by making it of cast iron with
suitable lugs for fastening to the said frame standard at each end, I utilize the
tray at the same time as a stay for the framing. The receptacle X shewn in
dotted lines underneath the hopper may suitably rest on a lower stay or cross
connection for the framing. The framing may also be stayed by a cross
connection R. By this means it is more convenient for use than if stood on the floor
as heretofore. The framing may be provided with wheels or castors O for easy
removal from place to place. Instead of the toothed wheel gear described and
which I prefer I may use friction wheels or sprocket wheel and chain connection
or other suitable gearing arranged latterally to the rollers.
Fig. 5 is an end view and Fig. 6 a side view of a modified arrangement of wheel
gearing whereby I obtain larger tooth wheels than in the previously described
construction. On the top roller spindle I fix a large tooth wheel F and on the
bottom roller spindle a similar one E. The wheel F gears with the pinion H on
a fixed stud in the framing and this pinion again gears with a broad toothed
pinion which can turn on a stud fixed in the framing of the machine the
pinion G carrying a fly-wheel L. This pinion also gears with the wheel E on the
lower roller spindle.
Instead of the springs acting upon the levers D weights may be used attached to
sector wheels of such a cam shape as to increase the leverage on which the weight
acts in proportion to the increase of space between the rollers.
In a modified arrangement of this gearing I fix the large tooth wheels F and E
respectively on one end of the upper roller spindle and on the opposite end of the
lower roller spindle a large tooth-wheel. These gear each into a latterally
arranged intermediate pinion running on fixed gudgeon and these pinions again
gear into pinion on what I may call a first motion shaft having its bearings in the
two end frames.
Fig. 7 is an end view and Figure 8 a part side view of a machine with cast
iron framing B provided at each end with a projecting bracket with boss 133 upon
which the socket or sleeve B can work up and down. The sleeve 13+ contains the
helical spring I and is screwed on to the lower end of the rod K. The wheel
gearing may be as here shown (that is to say like in Figures 5 and 6) or as previously
otherwise described.
It will be noticed that in the constructions shown the machine is quite clear
above the top of upper roller, so that any long articles to be mangled (as for
instance table cloths, sheets or curtains) can be wound round and round the upper
roller and receive a good gloss.
Having now particularly described and ascertained the nature of this said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
-
First. In mangling machines and other machines with similar compressing roller
arrangement the application and use of intermediate wheels for communicating
motion from one roller to the other the said wheels being arranged on one side so
as to insure full gear at all times with varying space between the rollers sub-
stantially as described and shown.
Second. In mangling machines and other machines with similar compressing
roller arrangement the application and use of levers forming the bearings for one
of the rollers and connected to springs or weights for increasing the resistance in
proportion to the space between the rollers substantially as described and shown.
Third. In mangling machines the arrangement of the tray B* in such manner as
to act as a stay to the framing and also to be adapted to catch the water under the
middle of the machine substantially as described and shown.
