PROVISIONAL SPECIFICATION.
Improvements in Woollen Drying Felts.
I, THOMAS RUFUS HARDMAN of the firm of Thomas Hardman & Sons of Bury
in the County of Lancaster, Manufacturer, do hereby declare the nature of this
invention to be as follows:
This invention relates to woollen drying felts such as are used in paper machines
for the purpose of conveying the paper around the drying cylinders, and its object
is to increase the durability of the felts.
For the purpose of my invention, I increase the quantity of weft upon that
surface of the fabric which is most exposed to wear whilst in use. This is
accomplished most conveniently by using two warps, one of which I will call the
ordinary warp and the other the binding warp. The ordinary warp is threaded
through the healds in the usual manner, and it may be woven also in the usual
manner with the exception that certain of the picks of weft float over all the ends
of the ordinary warp. These float picks will be determined in each case by the
increased quantity of weft required on the surface. Thus, by way of example,
every second or every third pick may be a float pick.
The binding warp is threaded with one end through each eye and is employed
solely to bind or secure the float picks of weft into the body of the felt.
After weaving, the felt is milled and treated in the usual manner.

Improvements in Woollen Drying Felts.
I, THOMAS RUFUS HARDMAN, of the firm of Thomas Hardman & Sons, of Bury
in the County of Lancaster, 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 :-
This invention relates to woollen drying felts such as are used in paper making
machines for the purpose of conveying the paper from the wire around the
drying cylinders, and its object is to increase the durability and pliability of
such felts.
For the purpose of my invention, I increase the quantity of weft upon that
face of the cloth or fabric which is the more exposed to wear in use.
This may
be most conveniently accomplished by using two warps, one of which I will call
the ordinary warp and the other the binding warp.
The ordinary warp is threaded through the healds in the usual manner, that is
to say with two or more ends in each eye through which this warp is passed.
The binding warp is threaded with only one end in each eye, and it is employed
solely for the purpose of binding in the float picks of weft which I employ for
the purpose of my invention.
The weft in each, or in certain of the picks, is caused to float over the ordinary
warp threads and is bound into the cloth by the binding warp threads. Which
picks are to float will be determined in each case by the increased quantity of weft
required on the face of the fabric. By way of example, I may make every second
or every third pick a float pick, and generally should do so.

page_text: After being woven as hereinbefore described, the fabric is milled and finished
in the usual manner.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is :-
A woollen drying felt having its weft or a portion of its weft floating over the
ordinary warp threads, and having the float threads of weft bound into the fabric
by binding warp threads, substantially as and for the purpose hereinbefore
described.
