Improvements in Apparatus for Pressing Travelling Fleeces of
Wool and such like Materials.
We, IGNATIUS SINGER, Analytical Chemist, and MORITZ WOLFF. JUDELL, Merchant,
both of Gresham House, Old Broad Street, in the City of London, 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:-
Fleeces of wool or such like materials are often passed through liquids for the
purpose of cleansing, washing or otherwise treating them; and, in order to expose
the fibres fully, and at the same time to secure continuity in the movement of
the material through the liquid, the fleeces are carried between two porous travelling
webs or aprons of wire gauze or other openwork. After the fleeces have thus
been carried through the liquid it is necessary to squeeze or wring them so as to
express a large portion of the liquid which they carry with them; it is difficult
to effect this by pressing rollers, because the travelling aprons in passing through
between the rollers undergo the pressure, shielding much of the material which
they carry with them, and being themselves subjected to distortion and damage.
Our invention relates to an arrangement of squeezing and guide rollers in such a
manner that fleeces carried betweon continuous travelling aprons are separated
from these aprons just before reaching the squeezing rollers, and after undergoing
the pressure of the rollers, are again engaged between the aprons, which are
carried past the squeezing rollers without being subjected to their pressure. For
this purpose we arrange the squeezing rollers in combination with guide rollers
as is shewn diagrammatically by the accompanying drawing. A and B are the two
travelling aprons having the fleeces C between them. At the first guide roller F
the apron A separates from the fleece and passes up and over the two guide
rollers G and H to the roller K where it rejoins the fleece. The apron B carries
the fleece onwards to the guide roller L and then separates from it passing down-
wards to the guide roller N then upwards over M to rejoin the fleece at K.
While the aprons take the course described, the fleece passes through between
the pressing rollers DE and when it reaches the guide rollers K and M it
becomes again engaged between the aprons A and B by which it is carried onwards
for such further treatment as may be required. Although the accompanying
drawing is only diagrammatic representing the relative positions and movements
of the rollers, it is to be understood that these may be constructed and mounted
in any known way and driven by any suitable gearing. The upper pressing
roller D necessarily has sliding bearings with the necessary pressure applied to
them by screws or otherwise, and preferably through springs admitting of a little
yield to thicker parts of the fleece. Also the two upper guide rollers G H and
the lowest guide roller N should have bearings adjustable so as to take up slack
of the aprons A and B if necessary.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
In apparatus for pressing fleeces of wool and such like materials carried between
travelling aprons, in combination with a pair of pressing rollers, guide rollers

rollers, while the fleece passes alone through the bite of the pressing rollers
substantially as and for the purposes set forth.
