PROVISIONAL SPECIFICATION.
Improvements in or connected with the Foundation of Card Clothing.
I, ELIJAH ASHWORTH, of the Moss Brook Works, Collyhurst, Manchester, in
the County of Lancaster, Machine Maker, do hereby declare the nature of this
invention to be as follows:-
My said invention relates to card foundation and has for its object so to treat
the foundation as to render it impervious to moisture and atmospheric influences,
which at present have a deteriorating effect upon the card clothing.
In carrying my invention into effect I apply paraffin wax to the foundation,
which renders the foundation repellant to moisture and tends to preserve it,
whilst at the same time not affecting its flexibility.
Further the effect of the treatment with paraffin wax is to give additional
solidity to the foundation enabling the wire to be set with greater regularity.
The wax also serves to lubricate the wire dents when the clothing is being ground
or worked in the carding engine.
Although my invention may be applied to all descriptions of card foundation,
it is particularly applicable to the foundations made in accordance with Specifica-
tions No. 14295 of 1895 and No. 14063 of 1896 for which I have obtained Her
Majestys Letters Patents.
I prefer to apply the paraffin wax in a melted state, the wax being contained
in a tank or trough to which heat is applied. The foundation is run through the
bath of melted paraffin wax in a spiral fashion or at a suitably slow speed to
provide for the requisite length of immersion and excess of wax is expressed by
a pair of squeezing bowls, the excess being returned to the tank.
Thus the foundation is thoroughly saturated and all the interstices of the fabric
are filled up with the paraffin wax.
I may however apply the paraffin wax to the foundation in a solid state the
paraffin wax being well rubbed into the foundation.
After treatment with the paraffin wax the foundation may be burnished or
pressed.
Dated this 7th day of July 1898.

I, ELIJAH ASHWORTH, of the Moss Brook Works, Collyhurst, Manchester, in
the County of Lancaster, 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, that is to say:-
My said invention relates to card foundation, and has for its object so to treat
the foundation as to render it impervious to moisture and atmospheric influences,
which at present have a deteriorating effect upon the card clothing.
In carrying my invention into effect, I treat the foundation with wax, which
renders the foundation repellant to moisture and tends to preserve it, whilst at
the same time not affecting its flexibility.
I have found in practice that the most economical wax for the purpose, is paraffin
wax, applied to the foundation in a melted state.
In addition to rendering the foundation repellant to moisture, the effect of the
treatment with paraffin wax is to give additional solidity to the foundation,
enabling the wire dents to be set with greater regularity. The wax also serves
to lubricate the wire dents when the clothing is being ground or worked in
the carding engine.
My invention is particularly applicable to foundations consisting of a plurality
of layers of woven material stitched or otherwise bound together in accordance with
Specifications No. 14295 of 1895 and No. 14063 of 1896 for which I have obtained
Her Majesty's Letters Patents.
I prefer to apply the paraffin wax in a melted state, the wax being contained
in a suitable tank or trough to which heat is applied. The foundation is run
through the bath of melted paraffin wax at a suitably slow speed, to provide for
the requisite length of immersion. Any excess of wax picked up by the foundation
is expressed by a pair of squeezing bowls, the excess being returned to the
tank.
Thus the foundation is thoroughly saturated and all the interstices of the fabric
are filled up with the paraffin wax.
I may however apply the paraffin wax to the foundation in a solid state, the
paraffin wax being well rubbed into the foundation.
After treatment with the paraffin wax, the foundation is preferably burnished
or pressed between smooth rollers.
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
1) Treating the foundation of card clothing with wax for the purposes in the
manner and substantially as herein described.
2) In combination with card teeth a foundation composed of a plurality of layers
of woven material stitched or otherwise bound together and treated with wax for
the purposes and substantially as herein described.
