PROVISIONAL SPECIFICATION.
Improvements relating to Wool-washing Machines.
I, ALEXANDRE DERU, of Verviers, in the Kingdom of Belgium, Manufacturer, do
hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in wool washing machines and consists of
an elevator for the wool whereby the usual endless band or apron on which the wool
is carried from the trough to the compressing rollers is dispensed with. Such endless
hands or aprons being made of metallic rods often need repair and consequently
cause the working of the machine to be frequently interrupted. The delay caused by
these interruptions is obviated when using a wool washing machine provided with the
elevator forming the subject of this invention.
In carrying out my invention I provide the trough of the wool washing machine
with a rotating shaft on which I arrange arms provided with supports between which
are arranged rakes turning on pivots. The rakes carry at each end two small arms
arranged at right angles to each other and carrying rollers. Each side of the trough
is provided with a curved part, one of the curved parts acting on one set of rollers,
the other curved part acting on the other set of rollers. When the shaft turns in one
direction the rakes enter the water vertically and, as the movement of the shaft
continues, one of the rollers comes against one the curved parts which causes the
rake to move through the water and carry along the wool contained therein to the
compressing rollers. As the shaft continues to revolve the roller leaves the curved
part and at the same time the other roller pertaining to the same rake comes against
the other curved part which causes the points of each rake to rest or "dwell" for a
certain time near the point of contact of the two compressing rollers whereby the
wool raised from the trough by the rakes is in all cases taken up by the said
compressing rollers. As the endless bands or aprons in front of the compressing
rollers are dispensed with my improve.l arrangement possesses the further advantage
of allowing the troughs to be shortened, which is of great importance especially as
wool washing machines are generally constructed with several troughs.

COMPLETE SPECIFICATION.
Improvements relating to Wool-washing Machines.
I, ALEXANDRE DERU, of Verviers, in the Kingdom of Belgium, Manufacturer, 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 improvements in wool washing machines and consists of an
elevator for the wool, whereby the usual endless band or apron on which the wool is
carried from the trough to the compressing rollers is dispensed with. Such endless
bands or aprons being made of metal rods often need repair and consequently cause
the working of the machine to be frequently interrupted. The delay caused by these
interruptions is obviated when using a wool washing machine provided with the
elevator forming the subject of this invention.
In the accompanying drawing,
Figures 1 and 3 are vertical longitudinal sections and
Figure 2 is a transverse section of part of the trough of a wool washing machine
provided with an elevator constructed according to my invention.

page_text: Figures 4, 5 and 6 are views of parts of the elevator drawn to an enlarged scale.
In carrying out my invention 1 provide the trough A of the wool washing machine
with two standards X X in which is mounted a rotating shaft B carrying wheels I I
having mounted on their peripheries brackets or bearings K in which work the
pivots of rakes C shown most clearly in vertical sections at figures 4 and 5 and in
plan at figure 6. The rakes carry at each end two small arms arranged at right
angles to each other and carrying rollers E and respectively. The sides of the
trough are provided with curved plates M figure 1 and N figure 3 respectively the
plate M acting on the rollers D and the other plate N acting on the rollers E. When
the shaft B revolves in the direction indicated by the arrows the rakes C successively
enter the water vertically and, as the shaft continues to revolve, the rollers D
successively come against the curved plate M which causes each of the rakes C to
move through the water and carry along the wool contained therein to the compressing
rollers H H as shown in figure 1. The roller D then moves out of contact with the
curved plate M and at the same time the other roller E pertaining to the same rake
comes against the other curved plate N which causes the points of the rake to rest or
"dwell
for a certain time near the point of contact of the two compressing
rollers H H whereby I ensure the wool raised from the trough by the rakes being
taken up by the said compressing rollers. As the endless bands or aprons in front of
the compressing rollers are dispensed with my improved arrangement possesses the
further advantage of allowing the troughs to be shortened, which is of great
importance especially as wool washing machines are generally constructed with
several troughs.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is :-
1. Elevating mechanism for wool-washing machines in which a number of pivotted
rakes are brought into contact with two curved plates such as M and N and thereby
operated in such a manner that their points are caused to dwell for a time near the
point of contact of two compressing rollers, substantially as hereinbefore described.
2. The improved wool washing machine hereinbefore described with reference to
the accompanying drawing.
