JEFFERSON, all of Bradford, in the County of York, Machine Makers and Iron-
founders. "IMPROVEMENTS IN MACHINERY FOR WASHING FIBRES AND FABRICS."
This Invention relates to improvements in machines for washing fibres and
fabrics; and according to this our Invention we employ (by preference) three
rollers, the lower one being below the water line; the upper rollers are also
partially immersed; the first nip is below the water line, the second or finishing nip
is above and clear of the water, thereby first securing a nip of the fibres or fabrics
whilst hot and saturated with water or suds, the other nip completing the
squeezing. The ordinary feed motion is dispersed with; the wash of the "forks'
passes the fibres to the nip of the lower rollers. In washing fibres or fabrics they
may be fed into the nip of the lower rollers by hand in what is known as "hand
washing."
"
In some cases a first pair of squeezing rollers immersed, and a second as finishing
pair behind, or at a higher level, or above the water are employed, a short feed apron
or a feed roller or rollers passing the fibre from the first to the second pair; or the
immersed rollers may deliver the fibre to an apron to be conveyed to any adjoining
bowl to be there further operated upon. The "wrapping" of the roller is more
durable by reason of its working in the suds or below water. It will be understood
the Invention is equally applicable to what is known as backwashing machines.

page_text: the apron 8; or a revolving fan 71 may be used instead of the roller 7, or this
roller 7 may be of iron so as to serve as an additional or second dry nip. If wood
be used for roller 7 it must not touch roller 6 (Fig. 2) so as to prevent fibre adhering
to roller 6, as stated; but if made of iron it must be in contact with and bear upon
roller 6. At 9 is a fork worked on fulcrum 10 by means of a crank 11 and rod 12,
so as to give a radial motion to the said fork, whereby the fibre is passed or floated
from the wash bowl to and between the rollers 4 and 5 (Fig. 2), as described.
13 is an enclosed guide plate extending nearly the width of the bowl, so as to
facilitate the passage of the fibre to the nip of the rollers 4 and 5. At 14 is a
screw adjustment in which is suspended the roller 6, so that its position relative to
the roller 4 may be accurately adjusted and determined. At each side of the
machine are radious arms 15, which carry the wood or iron roller 7. The other end
of the radious arms 15 is on the axis of the wrapped roller 5, so that when the
roller 7 is thrown up or raised it at all times maintains an uniform position in
relation to the wrapped roller 5. At 16 and 17 is a rack and pinion. When the
hand wheel 18 is turned the rack 17 is raised in its slide until the foot piece 19
comes under the weight lever 20, so as to raise the latter and take the weight off
the wrapped roller 5 during the night or when the machine is not in use, so as to
prevent the formation of a flat place on the wrapping of roller 5. 21 is a movablo
fulcrum pin on which the weighting lever 20 rests. The lever 24 has recesses 22, 23,
that the pin 21 may be received in either, so as to vary the amount of weight put
upon the wrapped roller by the lever 24.
The machine is geared as follows:-Wheels 1 and 4 (see Fig. 5) are on axis of
roller 6; the wheel 1 gears with a stud wheel 2. The latter drives wheel 3 and
bottom roller 4, whilst the wheel 4 on axis of first driver gears with and drives
the wheel 5' on axis of wrapped roller 5. The wood roller 7 is driven by ordinary
gear from opposite end of macbine.
Having thus fully described the nature and particulars of this our said.
Invention, together with the manner in which the same is to be or may be
performed or carried into practical effect, we would have it understood that we
claim as our Invention,-
Firstly. The construction, and arrangement, and use in combination of the
rollers 4, 5, fork 9, and incline 13, as described and illustrated by Fig. 1, 2, 3,
and 4 of annexed Drawings.
•
Secondly. The application to and use in combination with rollers 4-5 of the
outer trough or casing 6¹, for purposes and as described and shewn by Drawings.
In witness whereof, I, the said Joseph Jefferson, for and on behalf of myself and
the said Cornelius Jefferson, Lazarus Jefferson, and Mordecai Jefferson, have
hereunto set my hand and seal, this Seventeenth day of February, in the
year of our Lord One thousand eight hundred and eighty one.
