Improvements in Washing Machines.
WILLIAM GEORGE HANNA of 24 Wellington Place Belfast Ireland, Agent do
hereby declare the nature of this invention to be as follows:-
The object of this invention is to remedy a defect in washing machines as hitherto
made which have vertical rotating blades inside a stationary casing with ribs inside it.
The defect being the liability to injure the goods being washed by tearing or nipping
them between the revolving disc which forms the base for the revolving blades and
the stationary surrounding flange or segment on the inside of the casing.
To prevent the goods that are being washed from being caught in the space between
the revolving disc and the stationary internal flange or segment I make the adjacent
surfaces of the revolving disc and stationary flange or segment bevelled instead of
vertical or horizontal as hitherto made and instead of the rotating blades being
entirely within the diameter of the disc, I make a part of the rotatory blades project
beyond the rim of the disc but not touching the segment or stationary internal flange,
so that when the blades revolve the goods are thrown outwar is past the joint between
the revolving disc and the internal stationary flange or bevelled segment.
The revolving disc is supported at its outer edge by a ring carried on arms
attached to a boss fitted to the vertical spindle.
And to lessen prevent or divert the current of water from passing between the
bevelled faces in addition to the holes usually in the revolving disc, I also make
holes in the stationary internal flange or segment so as to connect the spaces above
and below the disc and stationary flange or segment which surrounds it.
Both the disc and the internal flange or segment I prefer to be made of metal as
being less liable to warp or twist out of shape.
Provision is also made for raising or lowering the spindle which carries the disc
ring and blades so that the bevelled faces may be made to work as close as desired.
These various devices and improvements effectually prevent the goods in process of
washing from being caught or nipped in the space between the disc and flange or
segment and remedy an admitted defect in this make of washing machine.

Improvements in Washing Machines.
WILLIAM GEORGE HANNA of 24 Wellington Place Belfast Ireland Agent 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 remedy a defect in washing machines as hitherto
made which have vertical rotating blades inside a stationary casing with ribs inside it.
The defect being the liability to injure the goods being washed by tearing or nipping
them between the revolving disc which forms the base for the revolving blades and
the stationary surrounding flange or segment on the inside of the casing.
The means employed to remedy this defect are illustrated in the drawing herewith
in which Fig. 1 is a vertical section of the machine and Fig. 2 a horizontal section
of the machine which is designed to be driven by a belt. The same letters and
figures of reference are employed to indicate the same or like parts.
To prevent the goods that are being washed from being caught in the space
between the revolving disc (a) and the stationary internal flange (b) I make the
[Price 6d1

page_text: adjacent surface of the revolving disc (a) and stationary segment or flange (b)
bevelled instead of vertical or horizontal as hitherto made and instead of the rotating
blades (a) being entirely within the diameter of the disc (a) I make a part of
the rotating blades (a) project beyond the rim of the disc (a) but not touching the
segment or stationary internal flange (6) so that when the blades (a¹) revolve the
goods are thrown outwards past the joint or space between the revolving disc (a)
and the internal stationary flange or bevelled segment (b). The projection of the
rotating blades (a') throws the goods over the perforations in the segment (b) and so
they are between the contrary currents produced by the rotating blades (a¹) and the
stationary projections (d) on the inside of the casing.
The revolving disc (a) which is preferably made of copper or other material not
liable to corrode is supported at its outer edge by a ring (a²) carried on arms (a³)
attached to a boss fitted to the vertical spindle (c).
To lessen prevent or divert the current of water from passing between the bevelled
faces in addition to the holes usually in the revolving disc (a) I also make holes (b¹)
in the stationary internal flange or segment (b) so as to connect the spaces above and
below the disc (a) and stationary flange or segment (6) which surrounds it.
Both the disc (a) and the internal flange or segment (b) I prefer to be made of
metal as being less liable than wood to warp or twist out of proper shape.
Provision is also made by means of a screw on the foot step (c) for raising or
lowering the spindle (c) which carries the disc (a) ring (a²) and blades (a¹) so that
the bevelled faces may be made to work as close as possible. These various devices
and improvements effectually prevent the goods in process of washing from being
caught or nipped in the space between the disc (a) and flange (b) and remedy an
admitted defect in this make of washing machine.
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 :-
In washing machines with blades revolving on a vertical axis making the blades
project past the joint between the disc and segment and making the adjacent faces
bevelled and also making holes in the segment all as herein described and illustrated.
