Improvements in Centrifugal Machines.
We,
JOHN LAIDLAW, of the Firm of Watson Laidlaw & Company, 98 Dundas
Street South, in the County of the City of Glasgow, North Britain, Engineers,
and JAMES WRIGHT MACFARLANE, Manager of the said Company, do hereby
declare the nature of this invention to be as follows:-
This invention relates to improvements in centrifugal machines and is more
particularly applicable to that form of centrifugal machine known as hydro
extractors which is used for drying clothes or other material, but it may be applied
to other centrifugal machines, such as cream separators. The machine has been
specially designed for use where power is not available, and can be driven by hand
power. The machine is constructed on the self balancing principle, and has
freedom to oscillate.
In carrying out our invention we provide a handle connected by toothed wheels
and pinions to a vertical spindle. The top of this vertical spindle is rounded, and
the shaft carrying the drun of the machine rests on the rounded top. A recess is
formed in the bottom of the shaft carrying the drum which is larger in diameter
than the spindlo connected to the handle. The spindle fits loosely into this recess.
A pin passing loosely through a hole in the spindle connects the shaft with the
spindle. A long sleeve or collar surrounds the shaft above and below the part
where the spindle and shaft.are connected, and opposite the place where the pin
connects the spindle and shaft there is a flange formed on the outside of the sleeve
or collar. Above and below this flange there is india-rubber or other elastic
packing between the aleove or collar and the framework of the machine. Owing
to the loose connection between the shaft and spindle and the elastic packing
between the sleeve or collar and the framework the revolving drum has freedom
to oscillate while the spindle connected to the handle remains vertical.

This invention relates to improvements in centrifugal machines and is more
particularly applicable to that form of centrifugal machine known as hydro-
extractors which is used for drying clothes or other material, but it may be applied

page_text: shaft with the spindle. A long sleeve or collar surrounds the shaft above and
below the part where the spindle and shaft are connected, and opposite the place
where the pin connects the spindle and shaft there is a flange formed on the outside
of the sleeve or collar. Above and below this flange there is india-rubber or other
elastic packing between the sleeve or collar, and the frame-work of the machine.
Owing to the loose connection between the shaft and spindle and the elastic
packing between the sleeve or collar and the frame-work the revolving drum has
freedom to oscillate while the spindle connected to the handle remains vertical.
Referring to the accompanying drawing which is a section of the improved
centrifugal machine.
A, is the framework.
B, the drum or basket.
C, the shaft carrying the drum.
A recess c is formed in the bottom of the shaft C to fit loosely over the rounded
end of a vertical spindle D. A pind passes loosely through a hole in the spindle
to connect the spindle with the shaft C. A long sleeve or collar E surrounds the
shaft above and below the part where the spindle and shaft are connected. A
flange e is formed on the outside of the sleeve or collar at about the same height as
the pin d. Above and below the flange e there is an india-rubber or other elastio
packing between the sleeve or collar and the frame-work A of the machine. The
loose connection between the shaft and spindle and the elastic packing between the
sleeve or collar and the framework allows of some freedom of self-balancing to the
drum.
The bandle F, which runs loose on the stud, has on its shaft a toothed wheel 'G
which gears into a pinion attached to the horizontal shaft H. A bevel wheel /'
gears into another bevel wheel i on the vertical shaft I. This vertical shaft I
carries a toothed wheel which gears with a pinion d', on the spindle D.
By this gearing between the handle and the spindle D'a.slow motion of the
handle will cause a very rapid revolution of the spindle D and drum B.
Having now particularly described and ascertained' the nature of our said inven-
tion and in what manner the same is to be performed' we declare that what we
claim is :-
1. The improved hand driven self-balancing centrifugal macbine, substantially
as described and illustrated on the accompanying drawing.
2. In centrifugal machines the combination of the loose driving connection
between the spindle D and the shaft C with elastically packed sleeve such as
described and illustrated on the accompanying drawings.
3. The combination with a centrifugal machine of a train of wheels of which the
first wheel runs loose on a stud, such as described and illustrated on the accompanying
drawings.
