Improvements in the Arrangement and Manufacture of the Parts
Forming the Driving Mechanism of Washing, Wringing, and
Mangling Machines.
We, WILLIAM SMITH, DAVID MARKS, and ROBERT WATSON, all of Britannia Iron
Works, Keighley, Yorkshire, Machine Makers do hereby declare the nature of this
invention to be as follows, that is to say :-
It consists of improvements in the arrangement and manufacture of the parts
forming the driving mechanism of washing, wringing and mangling machines,
having reference to that arrangement of driving mechanisms whereby motion is
imparted from the hand driving wheel, to which is fixed an eccentric, mounted on
which is a toothed wheel which gears with an internally-toothed wheel; to the rollers,
these said parts being old and well understood.
The difficulty heretofore experienced, when making use of the foregoing parts, has
been to obtain a regularly or uniformly rotary motion of the rollers at a suitable ratio,
and relatively, with that of the hand driving wheel. But by the employment of our
present improvements this difficulty
overcome.
As is well known, in order to impart motion to the above named internal wheel,
the wheel mounted on the eccentric must be held from revolving around its own
centre, while at the same time it must be free to revolve bodily with the eccentric.
This we accomplish by mounting, in any suitable manner, to the frame work of the
machine, two segment racks in gear with each other, to the outer end of each of which
is hinged a link or connecting rod, the other end of each of the said links being
hinged to a pin fixed to the face of the wheel mounted on the eccentric, one pin being
on one side and the other pin on the other side of the centre of same.
From the foregoing it will be seen that the before named wheel is freely allowed,
by the jointing or hinging of the segment racks and links, to move bodily with the
eccentric, but when attempting to revolve around its own centre, pulling at the link
on one side and pressing at the link on the other side of its centre, by the segment
racks gearing with each other, it is rigidly held.
Or in place of the segnient racks above described we might make use of two pendent
levers, to each of which are hinged the links as before described, care being taken to

page_text: adjust these said links, when laying hold of the wheel, at a proper angle to the before
named pendent levers. To keep the said pendent levers in the proper relative
position, at an appropriate distance from their fulcra is mounted or hinged a connecting
rod which joins the two together.
Respecting the manufacture of the foregoing parts, in casting we "chill" the before
named eccentric, as well as the joints of the segment racks and links, thus without
further labour giving them a smooth and hardened working surface.

page_text: Improvements in the Arrangement and Manufacture of the Parts
Forming the Driving Mechanism of Washing, Wringing, and
Mangling Machines.
We, WILLIAM SMITH, DAVID MARKS and ROBERT WATSON, all of Britannia Iron
Works, Keighley, Yorkshire, 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 consists of improvements in the arrangement and manufacture of the parts
forming the driving mechanism of washing, wringing and mangling machines,
and in order that the same may be more readily understood we have hereunto
appended a sheet of drawings illustrative thereof, bearing letters and figures of
reference used in the following description.
Fig. 1 is a side elevation of a sufficient portion of a machine to illustrate our
improvements, parts of same being shewn as cut away in order to shew parts that
would have been hid. Fig. 2 is a sectional view of part of fig. 1 on line A B. Fig. 3
is a similar view to fig. 2 but illustrates a modification in the formation and arrange-
ment of parts.
Cindicates the end frame of the machine.
This invention has reference to that arrangement of driving mechanisms whereby
motion is imparted to the rollers a b from the hand driving wheel c, to which is fixed
the eccentric d upon which is mounted the toothed wheel c that gears with the
internally toothed wheel frigidly attached to the wheel g. Said wheel g being fixed
on the shaft of the roller a and gearing with the wheel / fixed to shaft of the roller b ;
all the parts above mentioned being old and well understood.
The difficulty heretofore experienced when making use of the foregoing parts has
been to obtain a regularly or uniformly rotary motion of the rollers a at a suitable
ratio and relatively with that of the hand driving wheel c, said difficulty being over-
come by the employment of this our said invention.
As is well known in order to impart rotary motion to the internal wheel, the
wheel e must be held from revolving around its own centre or that of the eccentric d,
while at the same time it must be free to move bodily as said eccentric revolves.
This object we attain by mounting in any suitable manner to the frame work of
the machine, two segment racks kl, to gear with each other (we have shewn them as
mounted to the framing C¹ which also forms a cover for the wheels). To the outer
ends of said racks klare hinged the connecting rods or links m n respectively, the
outer ends of said links m n being respectively hinged to the pins op fixed or formed
on the face of the wheel e in the positions shewn by fig. 2.

page_text: From the foregoing it will be seen that the wheel e is freely allowed, by the
jointing or hinging of the racks kl and the links m n, to move bodily with the
eccentric d but when attempting to revolve around its own centre, pulling at the link m
and pressing at the link n or vice versa it is rigidly held.
Or in place of the segment racks k above described we might make use of the
two pendent levers r s fig. 3 to which are hinged the links m n respectively; said
levers r s
being sufficiently long and mounted in suitable positions so as to be at
appropriate angles to said links m n when the wheel e is mounted on the eccentric d
so as to allow said wheel'e to move vertically while the links m n allow its horizontal
motion. To keep said levers in the proper relative position the connecting rod t
is employed to couple the two together, the joints wv being loose to allow the necessary
movements.
Respecting the manufacture of the foregoing parts, in casting we "chill" the
eccentric d as also the joints of the racks k and the links m n, thus without further
labour, giving them a smooth and hardened working surface.
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 combination of the racks k l mounted on the framing C, and the links in n
with the wheels e and fand the eccentric d all arranged to operate substantially as
and for the purpose specified.
2. The combination of the racks and the links m n with the eccentric & all
constructed and arranged to operate substantially as and for the purpose specified.
3. The combination of the pendent levers 8, the connecting rod t and the links m n
with the wheels e and and the eccentric d all arranged to operate substantially as
herein set forth.
