PROVISIONAL SPECIFICATION.
Improvements in Seasoning Floor-cloths and the like.
I, FREDERICK WALTON, of No. 2, Eaton Place, Brighton, in the County of Sussex,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
In the manufacture of linoleum, corticine, and such like floor cloths, the pieces,
after they come from the rollers, are usually spread out or hung in a heated chamber
to become dried and oxidised. In order to render the surface sufficiently firm, this
operation involves a delay of several weeks, for it must be done at a moderate
temperature not exceeding 100° F., otherwise the surface is rendered uneven by the
expansion of gas or vapour under the coating. My invention relates to a method of
drying and oxidising fabrics of the kind referred to very quickly and efficiently,
which I effect in the following manner. I roll up the piece of fabric along with a
corresponding sheet of felt or other open fabric which prevents contact of the face of
the material of one convolution with the backing of the next convolution and at the same
time allows passage of air between the folds. I place the piece thus rolled, or several
pieces, in a closed cylinder heated by steam or otherwise, and I force into and through
the cylinder air under a pressure of several atmospheres and at a temperature which
may be as high as 200° F., allowing the air to escape through a loaded valve. The
fabric thus treated is properly seasoned, that is to say, dried and oxidised, in a few
hours. In order to ensure uniformity of treatment, the rolls may be caused to
revolve within the cylinder, and according as the nature of the material varies,
various gases or vapours such as oxygen, ozone, vapour of turpentine or chloride of
sulphur may be forced into the cylinder.

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 I
claim is -
The process for seasoning floor cloths and the like by coiling the material with
soft porous fabric interposed between its convolutions, and subjecting it to the action
of heated air or gas under pressure, substantially as herein described.
