Improvements appertaining to Wringing and Mangling Machines.
I, JOSEPH MATTHEW SELLERS, of the Firm of W. Sellers and Sons, of Keighley,
in the County of York, Machine Makers, do hereby declare the nature of this
invention to be as follows, that is to say:-
It relates to improved pressure regulating and driving mechanism for wringing,
and mangling machines whereby the desired pressure may be brought to act upon
the articles passing between the rollers of these machines while the toothed driving
wheels are at all times kept properly in gear with each other.
In carrying my invention into effect I mount the upper or yielding roller s0
that it is guided in its vertical or yielding movements by lever arms and in line
with the centre of oscillation of these I mount the driving wheel through which
motion is transmitted to the wheel secured on the shaft of said roller, by which
means no matter however said roller may move its wheels will be properly in gear
with each other, for the reason that its path of motion will be in the arc of a
circle in the centre of which is mounted the driving wheel as described.
The lever arms which may be straight or of bell crank form, are arranged so
that spring pressure may be made to act upon them for forcing the roller they
carry into contact with or towards the other roller, while adjusting screws are
used for regulating the force of said springs as is well understood.
In case the rollers are small and therefore may have as many revolutions as
the winch or handle, then the gearing wheels are straight spur wheels, but should
the rollers be large in diameter and therefore be required to make fewer revolu-
tions than the handle, then the driving wheels are arranged with the necessary
pinions for bringing about the desired result.
By arranging the pressure regulating and driving mechanism as above described
the framework necessary for carrying the several parts is considerably reduced
and so machines most suitable for fixing to a wash tub or clamping on a table
are produced as their reduced weight enables them to be readily handled.
Instead of the lever arms being employed quadrant slots made in the arc of a
circle about the centre of the top roller's driving wheel may be formed in the
framework to carry and guide said top roller, and in both this case and the one
herein before described, appropriately formed jointing pieces are employed for
coupling or mounting the pressure springs to act upon the top roller and the
screws to act upon those springs, the former by being of a suitably pivotted shape
while the latter is in the form of a ball and socket joint.
Dated this 22nd day of September 1897.

I, JOSEPH MATTHEW SELLERS, of the Firm of W. Sellers and Sons, of Keighley,
in the County of York, Machine Makers, 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, that is to say:-
It relates to improved pressure regulating and driving mechanisms for wringing
and mangling machines whereby the desired pressure may be brought to act upon
the articles passing between the rollers of these machines while the toothed driving
wheels are at all times kept properly in gear with each other.

tion:

my invention.

Fig. 2 is an elevation of said machine as seen at the end, where the driving
wheels and handle are mounted.
Fig. 3 is an elevation as seen at the end opposite to that shown by. Fig. 3.
Fig. 4 is a view of the machine as seen from above.
Figs. 5 and 6 are end elevations, similar to Fig. 2 but illustrate modifications
hereinafter explained.
In carrying my invention into effect I mount the upper or receding roller. a
so that it is guided in its vertical or receding movements by lever arms 6 b', and
in line with the centre of oscillation (as at A B Fig. 4) of these arms. I mount
the driving wheel c through which motion is transmitted to the wheel d secured
on the shaft of said roller a, by which means no matter however said roller a
may move, its lever arms, 6 61 will keep its wheel d properly in gear with the
driving wheel for the reason that its path of motion will be in the are of a circle
in the centre of which is mounted said driving wheel c.
The lever arms bb may be of bell-crank form or they may be of the shape
shown in the several figures, in the latter case (which is the one alone shown
since I preferably make use of it) they extend so that their respective adjusting
screws ff may come into contact with the pressure springs g g which act upon
them to force or tend to force the roller a into contact with the roller e; said
screws f f being for the purpose of regulating the pressure of said springs g g¹ as
is well understood.
When the rollers a e are of comparatively small diameter as shown by Figs. 1
to 4 inclusive in which case they have as many rotations transmitted to them as
are given to the handle h, the gearing wheels cd and km are straight spur wheels
the sizes of which are nearly equal, but should the rollers a e be of larger diameter
and therefore maintain the same surface speed as that of the smaller ones without
completing as many revolutions, then the driving wheels dc and m k are arranged
as shown by Fig. 6 in which case the handle is secured to the wheel.c and the
wheels dm are considerably larger in diameter than is said wheel c in this
manner the power transmitted through the handle to the rollers is greatly increased
at the expense of the speed of such handle.
By arranging the pressure regulating and driving mechanisms as above described
the framework necessary for carrying the several parts is considerably reduced and
so machines most suitable for fixing to a wash tub or clamping to a table are pro-
duced as their reduced weight enables them to be readily handled.
Instead of the lever arms being employed quadrant slots s made in the arc of

page_text: a circle about the centre of the top roller's driving wheel c, may be formed in
the framework t (see Fig. 5) to carry and guide said top roller a, and in this
case appropriately formed jointing pieces u w are employed for enabling the
pressure springs g to transmit their pressure to the roller a when it is in any of
its varied positions. Similar sockets are employed, and ball-ends formed on
the screws ff¹ (see Figs. 2 and 3) to take therein for enabling these latter to
act more freely on their respective springs 9 gl as and for the purposes that the
pieces u w above described, are used.
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. In a wringing and mangling.machine, driving mechanism having its parts
constructed and arranged to operate substantially as herein specified.
2. In a wringing and mangling machine, spring adjusting mechanism for trans-
mitting pressure to the rolle.'s of said machine as herein set forth and described.
3. Driving and pressure adjusting mechanism for wringing and mangling
machines the same being constructed and arranged to operate substantially as
herein specified.
