PROVISIONAL SPECIFICATION.
Improvements in Washing Machines.
WILLIAM WARNER Hope Drive The Park Nottingham Civil Engineer do
hereby declare the nature of this invention to be as follows:-
The object of this invention is to provide a better means of securing the centre
shaft in washing machines known as the rotary type.
Rotary washing machines are usually constructed with an inner cage made of
copper rods, gunmetal tubes or perforated metal. The body of the cage is
supported by ends having bosses keyed upon a centre shaft.
The cage is surrounded by a casing to contain the washing liquor and; the
articles to be washed are placed inside the cage.
It has been found in practice that the continual strain upon the keys and upon
the shaft is too much and consequently-the- shaft, becomes-loose-and-then there is
danger of great damage and there is also excessive wear and tear upon the working
parts.
My improvements consist in making the shaft with a solid flange near one end
which is attached to the cage end by rivets and the other end may be secured
by key.
It is obvious that these improvements may be adopted in a rotary washing
machine made in any kind..of material if it has a centre, shaft passing through
the cage.

Improvements in Washing Machines.
WILLIAM WARNER Hope Drive The Park Nottingham Civil 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 provide a better means of securing the centre
shaft in washing machines known as the rotary type.
Rotary washing machines are usually constructed with an inner cage made of
copper rods, gunmetal tubes or perforated metal. The body of the cage is
supported by ends having bosses keyed upon a centre shaft.
The cage is surrounded by a casing to contain the washing liquor and the
articles to be washed are placed inside the cage.
It has been found in practice that the continual strain upon the keys and upon
the shaft is too much and consequently the shaft becomes loose and then there is
danger of great damage and there is also excessive wear and tear upon the working
parts.
My improvements consist in making the shaft with a solid flange near one end
which is attached to the cage end by rivets and the other end may be secured
hv kev.

page_text: It is obvious that these improvements may be adopted in a rotary washing
machine made in any kind of material if it has a centre shaft passing through
the cage.
My invention is illustrated in the accompanying drawings.
Figure 1 represents a washing cage.
Figure 2 represents a section through part of the cage end plate and sleeve
attached to the shaft.
Figure 3 represents a broken part of one end shewing shaft and portion of the
end attached.
Like letters represent similar parts in each figure.
The body part of the cage in Figure 1 may be made of brass tubes or copper
rods passing through brass distance rings at 6 they also pass through the end.
plates d and e; these end plates are rivetted to the centre sleeve shown in dotted
lines at the end plate is also rivetted to the solid flange g which is part of the
shaft / thereby making a very strong attachment between the shaft end plates de
and 1.of cage.
Figures 2 and 3 are details shewing more clearly my invention. a represents
a broken tube forming the body part of cage e the end plate of cage is rivetted to
the flange of sleeve by rivets j this flange forming part of the end plate / is
attached by rivets & to the solid flange g of shaft h, thus the end is secured by
a ring of 10 rivets to the flange forming part of the shaft.
It is obvious that more or less rivets could be put in if needful.
The shaft h with the flange g is forged in one solid piece and afterwards turned
in a lathe to fit the sleeve and the end plate e and afterwards they are drilled
and rivetted with copper or brass rivets but it is also obvious that bolts would
answer the same purpose.
The other end plate d is rivetted to the end plate flange of the sleeve and the
sleeve is keyed upon the shaft at that end in the usual manner.
The ends of the shaft h are made to work in bearings in the casing of the
washing machine and the cage is made to rotate by gearing in the usual way.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed 1 declare that what
I claim is :-
The method of attachment between the centre shaft and cage of a rotary
washing machine, substantially as herein shewn and described.
Dated this 16th day of March 1896.
