Improvements in Washing Machines.
JOHN WOOD MANLOVE of 167 Walmer Road Notting Hill London the County
of Middlesex Mechanical Engineer do hereby declare the nature of this invention
to be as follows:-
The object of this invention is to increase the efficiency of rotary washing
machines and to make them more simple in construction, and to save time and
expense in taking them to pieces when required.
This invention consists of improvements in the washing cylinder and also in the
casing. The washing cylinder may be made of copper brass or other metal,, with
wire tubes or perforated sheets, so that the soap liquor may pass from the casing
into the washing cylinder either when it is standing or revolving. It may be divided
into two parts, or have midfuather "lifters" sliding doors are provided upon the
circumference for feeding and the withdrawal of the articles, each door is fixed in
such position, that when the articles fall to the bottom, the door about to be used
is opposite the door of the outer casing, without moving the cylinder much by
hand or other power.
Thus considerable time is saved in the process of
washing.
The outside casing may be made of steel, other metal or wood, having a door
at right angles with the ground level and upon the centre line of the machine.
The casing is divided into two parts diagonally at an angle of about 45 degrees
with the ground, the slope may be varied to suit the size of door or other
arrangements.
This construction will allow the removal of the washing cylinder, without moving
the standards or the ends of the machine or the lower connections and it is not
necessary to lift the washing cylinder more than clear of the end of the lower part
of the outer casing.
The jointing surface is upon flanges passing through the axis and held together
by bolts and the door is jointed upon a level surface by means of cross bar and
hand wheel. The arrangements for driving, supply of steam and water are similar
to those usually adopted. The machine constructed as described is thus simple
and efficient,

Improvements in Washing Machines.
I, JOHN WOOD MANLOVE of 167 Walmer Road Notting Hill London W. in
the County of Middlesex Mechanical 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 :
Rotary washing machines are usually constructed with an outside iron or steel
casing having a copper, brass, or galvanized iron washing cylinder made somewhat
in the form of a squirrel cage which is caused to revolve by suitable gearing
outside the outer casing.
The linen or other textile materials to be washed are fed through doors in the
outer casing into the washing cylinder, and the washing cylinder has doors to keep
the materials (whilst being washed) inside and prevent them falling into the casing
which are placed to open opposite the doors in the casing. The doors in the casing
wh

page_text: are closed upon steam tight joints which allow a little pressure inside the machine
and prevent the washing liquor splashing out.
In practice it is found very difficult to stop the machine with the door of the
washing cylinder opposite the door in the outer casing and therefore the cylinder
has to be moved by hand gearing at the end of the machine, until the doors are
opposite, so that goods may be fed or taken out of the cylinder. It is also difficult
to remove the inner washing cylinder when cleaning the machine or taking it out
for repairs.
The object of this invention is to facilitate the operation of washing and the
removal of the washing cylinder when needful.
This invention consists of improvements in the washing cylinder and also in the
casing to attain the above object.
The washing cylinder may be made of copper, brass or other metal, with wire,
tube, or perforated sheets, so that the soap liquor may pass from the casing into the
washing cylinder either when it is standing or revolving.
It may be divided into two parts or have midfeather or lifters, having sliding
doors upon the circumference for feeding and the withdrawal of the articles..
Each door is fixed in such position that when the articles fall to the bottom the
door about to be used is opposite the door of the outer casing without moving the
cylinder by hand or other gear, thus considerable time and power is saved.
The outside casing may be made of steel or other metals, or wood, having a
door at right angles with the ground and upon the centre line of the machine, and
the casing is divided in two parts diagonally at an angle of about 45 degrees
with the ground, the slope may be varied to suit the size of door or other
arrangement.
This construction will allow the removal of the washing cylinder after lifting the
top half of the outer casing without moving the standards or the end of the
machine, or the lower connections and it is not necessary to lift the washing cylinder
more than clear of the lower part of the outer casing.
The jointing surface is upon flanges passing through the axis and held together
by bolts and the door is jointed upon a level surface by means of cross bar and
hand wheel. The arrangements for driving, supply of steam and water are similar
to those usually adopted. The machine constructed as described is thus simple and
efficient.
That my invention may be clearly understood I have hereunto attached one
sheet of drawings illustrative thereof; marked with letters and figures of reference
corresponding with those in the following explanation. In all the figures the same
letters of reference when they occur indicate the same or corresponding parts.
Figure 1 is an elevation of the washing machine.
Figure 2. end view of the outer casing,
Figure 3. section taken on line A. B. Figure 1.
Upon reference to the figures, Figure 1, represents the whole machine a the
outer casing formed in halves at the point b. cis the door in outer casing having
a cross bar with catch to make a steam tight joint on the flat surface d. This
surface is formed by a casting to suit the curve on outer casing on one side and the
door on the other and is secured to the casing by rivets. e is the shaft to support
the washing cylinder and is supported through gunmetal bushes, glands, and
bearings. The pullies are constructed and secured in the usual way for driving
with straight and cross bolts for causing a reversing motion to the washing cylinder
and the belts are moved by the worm gear motion g which may be driven from the
shafting. h is a spur wheel geared into a pinion on the pulley shaft, j is hand gear
with friction clutch to stop and start the machine. I do not claim this gearing as
part of my Patent, but simply describe it to shew how the machine is driven. & are
connections for hot and cold water and is a safety valve.
Figure 2. illustrates more clearly the division in the outer casing shewing the
flange joint b.
It is obvious that when the bolts are taken out round this joint and pipes

page_text: disconnected, the top part of the casing may be lifted and thus free access to the
washing cylinder is obtained without disturbing the gearing or other parts. Eye
bolts may be placed at m for lifting,

Figure 3 illustrates position of door at n in the washing cylinder shewing their
position in relation to the divided part or midfeather, this figure also more clearly
illustrates the door e in outer casing and the seating d with flat and curved faces.
Steam supply is provided at o-and outlet for water at
C
P
The doors in the washing cylinder q are placed at about 45 degrees to the flat
division and directly opposite each other.
T
When the clothes are inside the washing cylinder, they are about equally divided,
half in each compartment, and as the cylinder revolves, the flat division or mid-
feather commences to lift up half the clothes, when the other half of the clothes
are about to fall from the top and the action of lifting half the clothes whilst the
other half is falling causes the cylinder to be in about the position indicated
immediately after they have fallen, and thus the door n in the cylinder is opposite
the door in the casing and in the right position for emptying one compartment.
If the clothes in the other compartment are emptied before another charge is
put into the one just emptied ready for washing the cylinder in that case must be
moved round by hand.
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
1st. A rotary washing machine having a divided outer casing as shewn and
described.
2nd. A rotary washing machine having a washing cylinder as shewn and
described.
