Improvements in Machines for Washing Fibres.
We JOSEPH JEFFERSON, Lazarus JeffeRSON and MORDECAI JEFFERSON
all of Brown Royd Works, Bradford in the County of York, Machine Makers,
do hereby declare the nature of this invention to be as follows:-
:-
This invention consists-Firstly of an improved construction, arrangement and
combination of levers and weights designed to ensure a relatively increased
efficiency therefrom, and a powerful weighting or nip of the squeezing rollers.
Secondly the invention consists of an improved construction and arrangement of
appliances for effecting the washing of the fibres.
According to this our said invention for applying weight to the nip rollers we
employ a standard on each side frame of the machine carrying a cross shaft or
studs on which are two quadrant levers the latter having a flanged boss or pulley
around the axis. The outer radius or arc of the quadrant has attached to it a
chain and weights and to the flanged boss or pulley is attached one end of a chain
the latter passing partly around the boss, thence extends and is attached to the
upper end of an upright lever the fulcrum of which is at its lower end and
preferably at a point linable between the nip of three squeezing rollers, the axis of
which rollers form about an equal triangle. Above the fulcrum of the upright
lever and attached thereto by slot and adjusting nut and bolt is a presser piece the
outer convex portion of which is received in a concave piece, connected with the
neck of the upper one of the three rollers the convex and concave surface constitute
a toggle joint so that the thrust of the upright lever is at all times direct and
linable with the axis of said roller.
There is a chain pulley worm and worm wheel by which the quadrant levers and
weights can be lifted so as to remove pressure from the rollers when for any
purpose necessary.
In some cases instead of the quadrant lever a 1 lever may be employed in which
case the weight chains are attached to the horizontal arm and a chain from the
vertical arm is attached to the upright toggle or pressure lever already described
herein.
The improvements connected with the washing comprise a sud bowl within which
is a grid or open work tray, this is immersed in the suds, above the grid is a
rectangular hollow frame preferably of wood or iron the outer surface of the
bottom of the said frame is provided with serrations or cross bars. The wool or
fibre to be washed is in the suds between the grid or tray and the bottom of the
rectangular frame.
The grid or tray is connected by rods or chains to a crank or tappet motion so
as to ensure a raising and lowering motion in the suds whilst the rectangular frame
by said cranks or tappets and connecting rods receives a reciprocating, lifting
advancing and a descending motion so that as the wool or fibre is lowered and
immersed in the suds by the grid then lifted in the suds to the underside of the
rectangular frame, the latter presses and squeezes the fibre on the grid and also
moves it forward in the direction of the squeezing rollers until reaching the outlet
from the bowl, which is by way of an inclined plane leading directly into the first
nip of the three rollers referred to. The improvements above described for fibre
washing machines are applicable to machines having two nip rollers, but we prefer
to use the triangle of three rollers and thereby secure two nips.

We JOSEPH JEFFERSON, LAZARUS JEFFERSON and MORDECAI JEFFERSON,
all of Brown Royd Works, Bradford in the County of York, Machine Makers,
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 :-
This invention consists Firstly of an improved construction, arrangement and
combination of levers and weights designed to ensure a relatively increased
efficiency therefrom, and a powerful weighting or nips of the squeezing rollers.
Secondly the invention consists of an improved construction and arrangement of
appliances for effecting the washing of the fibres.
Such being the nature and object of our said invention the following is a
complete description of same reference being had to the accompanying drawings in
which-
Fig. 1 is a side elevation of the improved device for applying weight or nip to
the squeezing rollers.
Fig. 2 is an end view of Fig. 1 one side or frame only of the washing machine
being shewn.
Fig. 3. is a side elevation of a washing machine shewing the improved construction
and arrangement of appliances for effecting the washing and forward feed of the
fibres, and also a modified form of weighting device for squeezing rollers.
Fig. 4 is a sectional end elevation of Fig. 3.
According to this our said invention for applying weight to the nip rollers 1. 1B 1C
we employ a standard 2 on each side frame 3 of the machine. The standard 2
each carry a cross shaft or studs 4 on which are two quadrant levers 5 one on each
side of the machine. Each quadrant lever 5 has a flanged boss or pulley 6 around
the axis 4. The outer radius or arc 7 of each quadrant 5 has attached to it a
chain 8 and weights 9 and to the flanged boss or pulley 6 is attached one end of a
chain 10 the latter passing partly round the boss 6, thence extending and attached
to the upper end of an upright lever 11, the fulcrum 12 of which is at its lower
end and preferably at a point slightly above the nip of the squeezing rollers 1. 1B 1°
so that the lap roller 1 presses harder on the finishing roller 1 than on the
roller 1B.
Above the fulcrum 12 of the upright lever 11 and attached thereto preferably
by slot and adjusting nut and bolt on which it is free to move is a presser piece 13
the outer convex portion 14 of which is received in a concave piece 15 connected
with the neck 16 of the upper one of the three rollers 1. 1B 1C the convex and
concave surfaces 14, 15 constituting a toggle joint so that the thrust of the upright
lever is at all times directly on the axis of said roller 1.
There may be a chain 17 pulley 18 worm 19 and worm wheel 20 (see Fig. 3) by
which the quadrant levers 5 and weights 9 can be lifted so as to remove pressure
from the rollers 1. 1B 1" when for any purpose necessary the worm wheel 20 being
turned by a hand wheel, screw key, or other device.
In some cases instead of the quadrant levers 5. 5 a lever 5A (see Fig. 3) may
be employed in which case the weight chains 8 and weights 9 are attached to the
horizontal arm 5A and a chain 10 from the vertical arm 5B is attached to the
upright toggle or pressure lever 11 already described.
The chain 10 is attached to a screwed rod 21 which passes through a hole or eye
in the upright lever 11 and a winged nut 22 on the end of the rod 21 allows of the
weight or pressure put upon the squeezing rollers 1. 1B 1° being readily adjusted
and regulated. A spring 23 is preferably interposed between the winged nut 22
and the upright lever 11. At 6 is a lug cast to the back of the quadrant 5 which

page_text: lug coming into contact with the forked part of the standard 2 prevents the
quadrant 5 turning over backwards and may also be used as a substitute for the
pulley 18 the chain 17 being attached to its outer end (see Fig. 3).
The improvements connected with the washing comprise an ordinary sud howl 1^
(see Figs. 3 and 4) within which is a grid or open tray 2. Above the grid 2 is a
rectangular hollow frame 3 preferably of wood or iron the under surface of the
bottom of the said frame 3 being provided with serrations or cross bars 4^. The
wool or fibre to be washed is fed into the suds in the grid or tray 2 between
the latter and the bottom of the rectangular frame 3.
The grid or tray 2 is connected by rods or chains 5. 5 to a crank or tappet
motion 6. 6 so as to ensure a raising and lowering motion in the ends whilst the
rectangular frame 3 by crank 7 and connecting rods 8 receives a reciprocating,
advancing and retiring, or to and fro motion, so that as the wool or fibre is lowered
in the suds by the grid 2 then lifted in the suds to the underside of the rectangular
frame 3, the latter presses and squeezes the fibre on the grid 2 and also moves it
forward in the direction of the squeezing rollers 1. 1B 1C until reaching the outlet
from the bowl 14 which is by way of an inclined plane 9B leading directly into the
first nip of the three rollers 1. 1B 1C referred to. The improvements above
described for fibre washing machines are applicable to machines having two nip
rollers, but we prefer to use the triangle of three rollers and thereby secure
two nips.
The open tray 2 always remains immersed in the suds in the bowl 1A and sand
or sediment from the wool escapes through the bottom of the tray 2 into the bottom
of the bowl 1ª.
Having now particularly described and ascertained the nature and object of our
said invention and in what manner the same is to be performed we declare that
what we claim is
1. The general construction, arrangement and combination of parts constituting
the improved weighting apparatus for weighting the squeezing rollers, as herein
described and substantially as illustrated by Figs. 1 and 3 of the accompanying
drawings.
2. The quadrant or L lever 5 weighted as herein described, the connecting link
or chain 10 upright lever 11 and winged nut 22 all in combination and as and for
the purpose herein described and substantially as illustrated by Figs. 1. 2 and 3 of
the accompanying drawings.
3. The general construction, arrangement and combination of parts constituting
the improved appliances for effecting the washing of the fibres, as herein described
and as illustrated by Figs. 3 and 4 of the annexed drawings.
4. In fibre washing machines a grid or tray placed in the sud bowl, and having
a rising and falling motion and a frame with a corrugated or ribbed under surface
inside the grid or tray and having a reciprocating to and fro motion as and for
purpose herein described and as illustrated by Figs. 3 and 4 of the annexed
drawings.
