Improvements in the Manufacture of Floor Cloths and other similar
Fabrics.
I HENRY MICHAEL STEINTHAL, of Scarborough, in the County of York, Floor Cloth
Manufacturer, do hereby declare the nature of this invention to be as follows :-
My invention relates to the manufacture of floor cloths and other similar fabrics
and more particularly to mosaic, tiled and marbled floor cloths or fabrics made as
described in the Specifications of Letters Patent granted to Samuel Hawksworth
respectively on the 6th June 1874 No. 1968 and the 17th November 1882 No. 5472
and has special reference to the drying and seasoning of the cloths or fabrics.
Hitherto it has been found necessary to leave cloths or fabrics in the drying rooms
for at least two years, the period varying according to the nature of the material and
the amount of drying oils therein when such have been used.
Now the object of my invention is to hasten the drying and seasoning process.
For this purpose I employ convoluted or other stoves producing a constant stream
of heated air along the floor cloth or other fabrics which together with a regulated
supply of oxygen dries and seasons the same in from one to six weeks according to the
temperature applied.

Improvements in the Manufacture of Floor Cloths and other similar
Fabrics.
I HENRY MICHAEL STEINTHAL, of Scarborough, in the County of York, Floor Cloth
Manufacturer, 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 invention relates to the manufacture of floor cloths and other similar fabrics
and more particularly to mosaic, tiled and marbled floor cloths or fabrics made as
described in the Specification of Letters Patent granted to Samuel Hawksworth
respectively on the 6th June 1874 No. 1968 and the 17th November 1882 No. 5472
and has special reference to the drying and seasoning of the cloths or fabrics.
Hitherto it has been found necessary to leave cloths or fabrics in the drying rooms
for at least two years, the period varying according to the nature of the material and
the amount of drying oils therein when such have been used.
Now the object of my invention is to hasten the drying and seasoning process.
For this purpose I submit the floor cloth or other fabrics to the action of constant
streams of heated air mixed with a regulated supply of oxygen, whereby the floor cloth
or fabrics are very rapidly dried and seasoned-say, in from one to six weeks according
to the temperature applied.
In carrying out my invention I hang the floor cloth or other fabric horizontally as
regards its length but vertically as regards its width in a drying room or shed which
has openings at its highest point fitted with powerful exhausters.
produce heated
air in chambers that are preferably external to the drying room or shed by means of
suitable stoves preferring what are known as convoluted stoves and I mix with the
heated air a regulated amount of oxygen gas the proportion being about from two to
four
this
per cent.;
oxygen may be derived from any suitable source such for example
as black oxide of manganese or permanganate of potash as is well understood.
I admit the mixture of heated air and oxygen in continuous streams to the lower
part of the drying room or shed and these streams rise vertically in contact with both
the front and back surfaces of the floor cloth or fabric their ascent being ensured or
facilitated by the exhausters. They escape at the top of the room or shed through
the openings already described so that they do not come in contact with the fabric
again. The oil in the fabric becomes rapidly oxidized and the solidification and
drying of the cloth are greatly accelerated without in any way making it brittle or
otherwise deteriorating it.
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 :-
In the manufacture of floor cloths and other similar fabrics, the submitting of the
cloths or fabrics to the action of streams of heated air mixed with oxygen substantially
in the manner and for the purpose hereinbefore described.
