PROVISIONAL SPECIFICATION.
Improvements in or applicable to Machines for Scouring and
Washing Wool and other Fibrous Materials.
We, JOHN MCNAUGHT and WILLIAM MCNAUGHT, of St. Georges Foundry,
Rochdale, in the County of Lancaster, Engineers and Machinists do hereby
declare the nature of the said invention, to be as follows:-
Our invention relates to an improved arrangement and combination of machinery
or apparatus for scouring and washing wool and other fibrous materials, the object
of which is to provide means by which sand, and other heavy foreign substances in
the liquor, which have passed along with the wool to the squeezing rollers may be
allowed to settle and become separated from the liquor, which freed from this
sediment is returned to the washing trough, and we carry out this object of our
invention by forming a settling tank along one side of the washing trough.
The liquor from the trough under the squeezing rollers is conveyed by a pipe to
a vessel in which works a rotary wheel having scoops this scoop wheel being the
same as those which are well known in connection with our wool washing
machines.
The scoops of the rotary wheel deliver the liquid into one end of the settling
tank at such a level that the liquor will flow along the settling tank into the
washing trough. As the liquor slowly flows along the settling, tank, the heavy
dirty particles form a sediment, and remain behind in the tank, whilst the liquor
thus freed from the sediment passes on into the washing trough.
This arrangement of settling tank may be used with other means of clevating the
liquor, but we prefer the rotary scoop wheel as the most simple.

COMPLETE SPECIFICATION.
Improvements in or applicable to Machines for Scouring and
Washing Wool and other Fibrous Materials.
WC, JOHN MCNAUGHT and WILLIAM MCNAUGHT, of St. Georges Foundry,
Rochdale, in the County of Lancaster, Engineers and Machinists, 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:
Our invention relates to an improved arrangement and combination of machinery
or apparatus for scouring and washing wool and other fibrous materials, the object
of which is to provide means by which sand, and other heavy foreign substances in
the liquor which have passed along with the wool to the squeezing rollers may be
allowed to settle and become separated from the liquor, which freed from this
sediment is returned to the washing trough, and we carry out this object of our
invention by forming a settling tank along one side of the washing trough.
The liquor from the trough under the squeezing rollers is conveyed by a pipe to
a vessel in which works a rotary wheel having scoops this scoop wheel being the
same as those which are well known in connection with our wool washing
machines.
The scoops of the rotary wheel deliver the liquid into one end of the settling
tank at such a level that the liquor will flow along the settling tank into the
washing trough. As the liquor slowly flows along the settling tank, the heavy

page_text: dirty particles form a sediment, and remain behind in the tank, whilst the liquor
thus freed from the sediment passes on into the washing trough.
This arrangement of settling tank may be used with other means of elevating the
liquor, but we prefer the rotary scoop wheel as the most simple.
Fig. 1 is a side elevation, and Fig. 2 a plan view of so much of one of our
machines for scouring and washing wool and other fibrous materials as will be
required to explain one modification of our invention.
Fig. 3 is a side elevation and Fig. 4 a plan view which will explain another
modification of our invention.
a, represents the washing trough; b, the endless lattice by which the wool or
other fibrous material is fed to the trough; c, is the shoot from the other end of the
trough down which the scoured and washed fibre passes to the squeezing rollers d,
from which squeezing rollers the material may be passed to an endless cloth or
lattice in any well known manner.
er
In the trough a, our well known toothed frames are suspended and worked,
(which are not shown in the drawings) for propelling the wool along the trough,
but other arrangements for propelling the wool or material may be used if desired
with our present invention.
Under the lower squeezing roller (d) there is a trough f, that receives the liquid
squeezed from the material, and such liquid or liquor is conveyed by a pipe 1, from
the trough, to the trough g, for the rotary wheel g', having scoops.
This trough is carried upon the main trough a, or by the sediment tank to be
hereinafter described, or partly by the trough and partly by the said tank.
The scoop wheel g¹, is of the construction and arrangement well known in our
wool washing machines, and the scoops elevate the liquid to a trough 92, from
which it flows into the settling tank h, arranged on one side of the main washing
trough a. When the settling tank h, is full up to a given level the liquid passes
out through an aperture ¹, at one end of the tank into the washing trough a.
Figs. 1 and 2 this aperture connects directly with the main washing trough, but
in Figs. 3 and 4 the liquid is conducted from the tank to the trough by the
pipe .
In
i, is a cock operated by the handle i, by which the liquid in the tank h, or in the
trough a, may be allowed to pass from one to the other at the level of the cock i,
when desired.
a', is the outlet valve in the bottom of the trough, and h², the outlet valve in the
bottom of the tank through which the liquor contained in the trough a, and in the
tank h, may be emptied, and through which the sediment may be washed away
when required.
9, is an overflow pipe from the scoop. wheel trough g, in case the liquid in it
should rise above a level fixed upon.
As before stated other means than the rotary scoop wheel (which is preferred)
may be used for elevating the liquor from the trough under the squeezing rollers to
the settling tank.
Having now particularly described and ascertained the nature of, our said
invention, and in what manner the same is to be performed we declare that what
we claim is.
The combination of a settling tank (h) with the washing trough (a) of machines
for scouring and washing wool, which tank (h) is arranged alongside the trough (a)
and into which tank (h) the liquid collected from the squeezing rollers is elevated
before being returned to the washing trough (a) substantially as and for the purpose
described and illustrated by the drawings.
