Improvements in the Construction of the Inner or Revolving
Cylinder of Rotary Washing Machines.
I, SIDNEY TEBBUTT, Mechanical Engineer, of 32 Avenue Road Leamington,
Warwickshire do hereby declare the nature of this invention to be as follows:—
My invention relates to washing machines where the cage, or cylinder, which
holds the clothes, revolves within an outer casing or cylinder, which holds the
washing liquor; and it consists of a new or improved method of constructing the
ends of such inner cage, or cylinder, so as to produce a better circulation of
the liquor over and through the clothes.
I form each end of the cage or inner cylinder, of a cast iron casting of a uniform
width of some two or three inches consisting of a boss, arms running from the boss
to the rim, and a rim. This casting is lined on the side which forms part of the
interior of the cylinder, with a sheet of brass, fastened to the casting by screws.
This brass sheeting has holes in it around and near the centre boss. The
casting upon its other or exterior side carries flanges, running along each
side of the arms, the inside of the rim, and the circumference of the boss. The
flanges form a continuous flange running round each segment of the casting, and
are a part of the casting itself. The section of this casting thus forms at the
circumference an L shape; and at the arms a T shape. The casting thus lined
on the inside with the metal sheeting forms a series of chambers or receptacles
various pairs of arms.
between
The m of action is as follows:-
The liq in the outer caseing flows into the cha of the casting which
for the timing is at the bottom, and as the chamber as with the revolution
of the cylind it carries with it a portion of the liquor which ngth flows toward
the boss at th centre, where it passes through the holes in the etal sheeting and
then enters the inside of the cylinder. By this means the liquor is continuously
but gently drawn upwards away from the bottom of the outer caseing and is poured
upon the clothes in the inner cylinder; this takes place at each end of the cylinder
as the above described castings are at each end and then a thorough circulation of
the washing liquor over and through the clothes is obtained.
As the construction of the ends is symmetrical, the machine operates in exactly
the same way when the motion is reversed, and the cage revolves in the opposite
direction.

1, SIDNEY TEBBUTT, Mechanical Engineer, of 32, Avenue Road, Leamington,
Warwickshire, 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 washing machines of the well known kind, which are

page_text: commonly called rotary washing machines, which have an outer receptacle, or
casing, containing the washing liquor, and an inner cylinder, or cage, which holds
the clothes and in which the liquor percolates through its sides and which revolves
within the outer ca-ing upon its axis sometimes in one direction, and sometimes in
another. The object of my invention is to produce a better circulation of the
washing liquor upon, around, and through the clothes, than is usually obtained, by
drawing liquor away from beneath the clothes and at the same time pouring it
upon them from above.
This result is accomplished by a special construction of the ends of the inner
cylinder or cage, whereby the liquor is carried up by pockets or troughs in these
ends, and is poured into the cage through the holes in the inside part of the ends
made near the centres and lying around the hubs.
The accompanying drawings shew these specially constructed ends.
Figure 1 shews the ends of the cage as seen from its inside.
Figure 2 shews the cage from a side view, with part cut away to shew part of a
longitudinal section made through the centre of one of the ends.
shewn on the body of the cage.

Figure 3 shews the ends of the cage as seen from the inside, with the metal parts
covering the inside removed.
Figure 4 shews one end of the cage as seen from the outside.
Figure 5 is an enlarged section of one of the ends of the cage.
Each end of the cage is formed of an iron casting in the form of a wheel (shewn
in section in Figs. 2 & 5 and in side view in Figs. 3 & 4), consisting of a hub or
boss, six arms or spokes H H dividing it into six segments, and a circumference or
rim; the whole casting being of about three inches in width and having upon its
outer side, as part of the casting and at right angles to the beforementioned parts,
a continuous flange F F running round each of its segments; such flanges making
with the arms in section a T shape (shewn at B in Figs. 2 & 3), and with the rim
an L shape, (shewn in Figs. 2 & 5), and forming with each other a continuous
surface upon the outer side of the casting with six triangular spaces or holes J J
between the arms. Upon the inner side of the castings is fastened, by means of
countersunk headed screws D D, a plate or disc of sheet brass, having holes A A
cut through it, at or near the centre, and in a circle around the hub of the
casting.
The size of these holes is about one inch by half an inch and two are in each
division. The castings with the plates or discs upon their inner sides thus form a
Beries of troughs or pockets between the various pairs of arms, running round each
segment or division, by which the liquor is held, and from which it can only escape
by the holes A A in the metal disc. The casting with its metal disc forms the end
of the cage. The cage is fastened to each of these castings by screws in the rim
(not shewn in the drawings). The ends of the axles C C, upon which the cage
revolves, are fastened in the hubs of the castings. A section of the lower part of
the outside casing holding the washing liquor is shewn in Figure 3 at K, with its
stand L. Each end of the cylinder is constructed in the same manner.
lettering in the various figures is the same.
The mode of action is as follows:-
The
The washing liquor at the bottom of the outer casing flows over the flange into
that division of the casting which for the time being is at the bottom of the
revolution, and fills the bottom part of the trough or pocket. As the cage
revolves, the liquor in the trough is carried upwards, first as shewu at W 1, and
then as shewn at W 2, when it pours through the holes A A into the inside of the
cage. The same thing takes place when it reaches the position shewn at W 3.
In this manner the liquor enters the cage, and is showered upon the clothes, whilst
at the same time the liquor at the bottom is drawn away from beneath the clothes
by the action of succeeding pockets. In consequence of the syminetrical
construction of the ends of the cage the same action takes place when the gearing
is reversed and the cage rotates the opposite way.

page_text: 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 :-
The construction of the ends of rotary washing machines in the manner herein-
3 before and in the accompanying drawings described and illustrated, and for the
purposes herein before mentioned.
