I EDWARD KEMPE of Holbeck Mills Leeds in the County of York Machine
Maker do hereby declare the nature of my invention for IMPROVEMENTS IN
MACHINERY FOR WASHING SCOURING DYEING & STIFFENING WOVEN OR FELTED
CLOTHS IN AN OPEN & EXTENDED STATE BY THE APPLICATION OF SQUEEZING
ROLLERS MADE OF METAL AND COMPRESSED CLOTH, to be as follows:-
This Invention relates to machinery for washing scouring dyeing and stiffening
woven or felted cloths and particularly to machines in which the pieces of fabric to
be treated sewn end to end are immersed in liquid contained in a vat, are drawn
continuously out from this vat by rollers which squeeze the liquid out from the
fabric and then allow the fabric to pass back again into the vat; this going on
continuously until the goods have been sufficiently operated upon.
During the whole of the treatment the fabric is maintained in an open and
extended state and creasing is as far as possible avoided.
A machine of this sort is described in the specification of a former patent
granted to me No 34 in the year 1885 and this machine is very suitable for use
in conjunction with the improvements to which my present invention relates.
Heretofore in this machine cast iron rollers have been employed and in some
cases a cloth has been wrapped around one of the rollers. Rollers covered with
vulcanised india rubber have also been used. Bare metal rollers used alone do not
operate satisfactorily and when a wrapping of cloth is applied it rapidly becomes
worn. On the other hand rollers covered with india rubber are subject to rapid
wear when as is frequently the case alkaline or acid liquors are employed in
the vat.
According to my invention I employ in such machines an upper pressing roller
formed of compressed cloth; many thicknesses of the cloth are arranged one on
the other the whole is consolidated by heavy pressure and the edges of the cloths
form the surface of the roller. Woollen cloth is cut into discs somewhat larger in
diameter than the roller required which conveniently will be about 12 inches and

page_text: these discs are threaded on to a metal bar adapted to serve as the axis of the
roller the bar is square in section at the parts where it receives the discs of fabric
upon it. These discs are accumulated in sufficient number to form a roller of the
desired length say six feet or thereabout-the discs when thus threaded upon the
bar are compressed by means of a powerful hydraulic press and they are confined
in a compressed state between end discs of metal which are securely fixed upon the
bar or axis this having been done the roller is rendered true and accurately
cylindrical by turning the surface in a lathe. An upper roller of compressed cloth
is used in conjunction with a lower roller of similar dimensions of cast iron or
other metal. The rollers are held together when in use by springs pressing on the
bearing of the upper roller and they are driven in the manner usual in machines of
this class.
In place of employing a metal lower roller one made of compressed cloth in all
respects similar to the upper roller may be employed, but this renders the machine
more expensive and a machine with a lower roller of cast iron and an upper of
compressed cloth on a metal bar or axis is found to work very efficiently. The
arrangement may be reversed the cloth roll being then the lower roll.
I would remark that I am aware that rollers of compressed cloth such as I have
described but of much smaller dimensions have before been employed in the
treatment of unwoven fibrous materials-I therefore make no claim to such rollers
generally, but my claim is confined to machines in which woven or felted cloths
joined up into an endless series are treated continuously substantially as described
being immersed in liquor in a vat withdrawn from the said vat by the rollers
squeezed and afterwards returned to the vat.

I EDWARD KEMPE of Holbeck Mills Leeds in the County of York Machine
Maker 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 relates to machinery for washing, scouring dyeing and stiffening
woven or felted cloths and particularly to machines in which the pieces of fabric to
be treated sewn end to end are immersed in liquid contained in a vat, are drawn
continuously out from this vat by rollers which squeeze the liquid out from the
fabric and then allow the fabric to pass back again into the vat; this going on
continuously until the goods have been sufficiently operated upon.
During the whole of the treatment the fabric is maintained in an open and
extended state and creasing is as far as possible avoided.
A machine of this sort is described in the Specification of a former patent
granted to me N° 34 in the year 1885 and this machine is very suitable for use
in conjunction with the improvements to which my present invention relates.
Heretofore in this machine cast iron rollers have been employed and in some
cases a cloth has been wrapped around one of the rollers. Rollers covered with
vulcanized india rubber have also been used. Bare metal rollers used alone do
not operate satisfactorily and when a rapping of cloth is applied it rapidly becomes
worn. On the other hand rollers covered with india rubber are subject to rapid
wear when, as is frequently the case, alkaline or acid liquors are employed in
the vat.
According to my invention I employ in such machines an upper pressing roller
formed of compressed cloth; many thicknesses of the cloth are arranged one on
the other, the whole is consolidated by heavy pressure and the edges of the cloths
form the surface of the roller. Woollen cloth is cut into discs somewhat larger in
diameter than the roller required which conveniently will be about 12 inches, and
these discs are threaded on to a metal bar adapted to serve as the axis of the
roller-the bar is square in section at the parts where it receives the discs of fabric
upon it. These discs are accumulated in sufficient number to form a roller of the
desired length, say six feet or thereabout-The discs when thus threaded upon the
bar are compressed by means of a powerful hydraulic press and they are confined
in a compressed state between end discs of metal which are securely fixed upon the
bar or axis this having been done the roller is rendered true and accurately
cylindrical by turning the surface in a lathe. An upper roller of compressed cloth
is used in conjunction with a lower roller of similar dimensions of cast iron or
other metal. The rollers are held together when in use by springs pressing on the

of this class.
In place of employing a metal lower roller one made of compressed cloth in all
respects similar to the upper roller may be employed, but this renders the machine
more expensive, and a machine with a lower roller of cast iron and an upper of
compressed cloth on a metal bar or axis is found to work very efficiently. The
arrangement may be reversed, the cloth roll being then the lower roll.
I would remark that I am aware that rollers of compressed cloth such as I have

treatment of unwoven fibrous materials-I therefore make no claim to such rollers
generally, but my claim is confined to machines in which woven or felted cloths
joined up into an endless series are treated continuously substantially as described,
being immersed in liquor in a vat, withdrawn from the said vat by the rollers,
squeezed, and afterwards returned to the vat.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:-
My improvements in machinery for washing scouring, dyeing and stiffening
felted cloths in an open and extended state consisting in making such machines
with squeezing rollers of compressed cloth on metal axes substantially as described.
