I, JOHN CHARLES. WALKER, trading as John Perry of Shipley Fields Mill, Shipley
in the County of York, Mechanical Engineer, do hereby declare the nature of this
invention, to be as follows:-
My improvements have reference to back washing machines generally, and the
object is to more perfectly cleanse and dry the material operated upon.
As the sliver or material passes through the bowl or trough containing the washing
liquor it is subjected to the action of a series of squeezing rollers whilst in the
liquor; and for this purpose a number of small rollers are arranged in a circular
position in the bowl or bowls and receive the required squeezing pressure from one
large roller mounted in sliding bearings over them, so that a pressing contact is
formed between each separate small roller and the aforesaid large roller; such
pressure can be varied if desired by means of weights or springs. As the material
is fed between each small roller and the large roller the liquor is squeezed out of
it, and as it afterwards passes along in the space between the squeezing points the
material or fibre opens again and at once becomes recharged with liquor, so that by
the frequent squeezing of the liquor out of the material and recharging of the same it
becomes thoroughly washed free from impurities. These squeezing rollers may be
made plain, fluted or perforated as desired.
After the above operation the material passes between pressing rollers to the drying
portion of the machine. The drying rollers of the machine are arranged in any
convenient position and are formed of perforated or open-work cylinders mounted and
revolving on fixed or revolving cylinders, pipes or domes, such cylinders, pipes or
domes being surrounded when required for increased radiation by collars, projections
or wings, and heated by steam or other suitable means.
The oiling apparatus for oiling the dried material as it passes from the machine is
mounted on the framework of the drying portion in such a manner that it can be
readily swung round and clear of the machine without damaging, deranging or dis-
connecting any of the parts thereof.

I, JOHN CHARLES WALKER, trading as John Perry of Shipley Fields Mill, Shipley
in the County of York, Mechanical Engineer, 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 improvements have reference to back-washing machines generally, and the
object is to more perfectly cleanse and dry the material operated upon.
In the accompanying drawings Fig. 1 is a part longitudinal section, and
Fig. 2 a plan of same. Fig. 3 is a part sectional elevation, and Fig. 4 is a
sectional plan, shewing parts of back-washing machine with my improvements
applied thereto.
A represents the trough or bowl containing the washing liquor. As the sliver or
material passes through the bowl or trough Ä it is subjected to the action of a series
of small squeezing rollers B and large squeezing roller C. The small squeezing
rollers B being arranged and mounted on suitable framework D in a circular position
(as shewn) in the bowl or trough A, so as to receive the required squeezing pressure
from the large roller C, resting upon them, so that a pressing contact is formed
between each separate small roller B and the large roller C. As the material is fed
between each small and the larger roller, the liquor is squeezed out of it, and as it
afterwards passes along the space between the squeezing points E the material or fibre
opens again and is recharged with liquor, so that by the frequent squeezing of the
liquor out of the material and recharging of the same, it becomes thoroughly washed
free from impurities.
The squeezing rollers B and C may be made plain, fluted or perforated as
desired.
Motion is imparted to the aforesaid small squeezing rollers B by means of suitable
gearing F, driven from any convenient moving part of the machine.
After the above operation the material passes between pressing rollers G, to the
drying portion of the machine, part of which is shewn at Figs. 3 and 4, such
drying rollers being arranged in any convenient position.
In my improvements the exterior of the drying rollers H are formed of perforated
or open work cylinders J, mounted and revolving on fixed or revolving cylinders K
as shewn, these being surrounded when required for increased radiation, by collars,
projections or wings L. The required heat is obtained direct from the steam chest M,
such steam passing within the cylinder or dome K. Air is admitted between the
cylinder or dome K and the outer perforated cylinder J through opening N and side
air ways P in the end of the dome K for the purpose of assisting in the drying
operation. The openings R in the collars L are for the purpose of allowing a free
passage of air from end to end of the roller H.

The oiling apparatus for oiling the dried material as it passes from the machine is
mounted on the framework of the drying portion in such a manner that it can be
readily swung round and clear of the machine without damaging, deranging or dis-
connecting any of the parts thereof.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what 1
claim is :-
1st. The arrangement and combination of small squeezing rollers B and large squeezing
roller C, applied to back-washing machines, substantially as and for purposes herein
set forth.
2nd. The arrangement of drying rollers H, formed of perforated or open work
cylinders J, in combination with means or apparatus for heating the same, substantially
as herein set forth.
