Cylinders of Washing Machines.
JOHN GREENALL 120 Portland Street Manchester, Steam Washer Manufacturer,
and THOMAS TANNETT HEATON, 111 Church Lane, Gorton near Manchester, in the
County of Lancaster, Engineer, do hereby declare the nature of this invention to be as
follows:-
This Invention has for its object Improvements in the apparatus for driving
the Cylinder or Cylinders of Washing Machines by means of a simple arrangement
for rotating the Cylinder or Cylinders of the Washer or Washers periodically in
diverse directions whilst still being driven by the same shaft-the reversing action
being automatic. The word "cylinder" as used here means any shaped box, tub,
cage or case in which the clothes or other articles to be washed are put.
The Invention consists in the combination of a worm & worm-wheel with and
driving an eccentric cam-groove which actuates a lever for the purpose of throwing
into action clutches which work toothed or other wheels in opposite directions so as to
actuate the central shaft of the cylinder and by this means enable the cylinder to be
worked in opposite directions for a given number of revolutions each way.

We JOHN GREENALL of 120 Portland Street Manchester Steam Washer Manu-
facturer and THOMAS TANNETT HEATON 111 Church Lane Gorton in the County of
Lancaster, 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 :—
The object of this Invention is to obtain automatically periodically reversed
revolutions of the cylinder, drum, box or tub of Washing Machines; this reversal of
motion being desirable to prevent the articles which are being washed from becoming
rolled together. The arrangement of driving gear with automatic periodically
reversing motion is as follows-
A pulley "A" is fastened to a shaft "B." To the same shaft is keyed a double
clutch "C" in such a way that it is capable of sliding into gear with either the bevil
wheel "D" or the bevil wheel "E" both of which are loose upon the shaft "B," &
have clutch teeth formed upon them into which the teeth of the double clutch "C"
engage. If the double clutch "C" is in gear with bevil wheel "D" the motion of
the third bevil wheel "F" (which is fastened to the cylinder or drum) is in one
direction. If the double clutch "C" is in gear with the bevil wheel "E" the motion
of the wheel "F" and the cylinder is in the opposite direction.
On the aforesaid shaft "B" is fastened a worm or endless screw "G" which
revolves with shaft "B" always in one direction and drives the worm wheel "H"
and the cam "J" which are both fastened to the shaft "K." In the cam "J" is a
groove "L" and into this groove projects a stud on the end of the double lever "M."
The groove
"L" is of such form and is so placed that during each revolution of the
cam "J" it imparts a reciprocating motion to the lever "M," each movement or stroke
of the lever "M" being succeeded by a period of rest. The motion is transmitted
through the lever "M" to the double clutch "C" causing it to slide out of gear with
one of the bevil wheels "D" and "E," and into gear with the other. During each
period of rest of the lever "M" the double clutch "C" is held in gear with one of the
bevil wheels D and E causing the third bevil wheel F and the cylinder or drum "N"
to revolve a certain number of times in one direction or the other. The number of
revolutions of the cylinder or drum "N" in either direction, before a reversal takes
place, depends upon the form of the groove L of the cam "J" in relation to the
number of teeth of the worm wheel H, as the length of the periods of rest in the cam
groove corresponds with the passage of a certain number of teeth of the worm
wheel "H" through the worm "G," each tooth representing one revolution of the
shaft "B."
The cam "J" may be of any suitable form for the purpose, and may either be a
disc with a groove in the face as shewn in the drawing which accompanies this
specification, or it may be cylindrical with a groove in its periphery, or otherwise.

The clutch "C" may be either a tooth clutch as shewn, or a friction clutch. Gearing
may be introduced between the bevil wheel "F" & the cylinder or drum, or between
the pulley "A" and the shaft "B" if required. The word Cylinder
this specification means either a cylinder, drum, box, cage or tub in which the articles
are placed to be washed.
as used in
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 :-
Novelty in the combination of a worm, worm wheel, cam, lever, clutch and three
bevil wheels for the purpose of obtaining an automatic, periodically reversing motion
of the cylinder, or drum, box, cage, or tub of a Washing Machine or Washing
Machines.
