Woven or Felted Fabrics.
I, WILLIAM Fox, of Cardigan Villas, Headingley, near Leeds, in the County
of York, Gentleman do hereby declare the nature of this invention to be as
follows
The object of my invention is to prevent tearing or other damage to the material
during the milling or fulling operation.
My improvements have reference to what is known as the "knocking off board."
This knocking off board is provided within the machine, and the material runs through
holes therein during the operation of milling or fulling, and should the "pieces
become knotted, twisted or otherwise entangled with each other, such knotted, twisted
or entangled part is unable to pass through the holes in the knocking off board,
consequently the board is lifted thereby, and it being engaged or connected with
the driving arrangement, throws the belt on to the loose pulley, or otherwise
disconnecting the driving arrangement, thus bringing the machine to a standstill.
Now it is found in practice that the material coming in contact with the sides
of the holes as it passes through, enlarges such holes by wear, and at the same
time frequently damages the material by tearing it on the sharp worn edges of
the holes. To prevent this damage I apply one or more guide rollers running in
suitable bearings attached to the underside of the knocking off board, by so doing
I am able to conduct the cloth through the knocking off board free or clear of
the sides, or so clear as to prevent any serious frictional contact therewith, at
the same time preventing the tearing or other damage which frequently occurs to
the material in passing through the knocking off board.

My improvements have reference to what is known as the "knocking off board."
This knocking off board is provided within the machine, and the material runs
through holes therein during the operation of milling or fulling, and should the
pieces" become knotted, twisted or otherwise entangled with each other, such
knotted, twisted or entangled part is unable to pass through the holes in the
knocking off board, consequently the board is lifted thereby, and it being engaged
or connected with the driving arrangement, throws the belt onto the loose pulley,
or otherwise disconnects the driving arrangement, thus bringing the machine to
a standstill.
Now it is found in practice that the material coming in contact with the sides
of the holes as it passes through enlarges such holes by wear. and at the same
time frequently damages the material by tearing it on the sharp worn edges of
the holes.
In the accompanying drawings Fig. 1 is a longitudinal section. Fig. 2 a transverse
section, and Fig. 3 a sectional plan, shewing part of a milling or fulling machine with
my improvements applied thereto.
A is the knocking off board, which is of ordinary construction, and through it are
provided the holes B for the passage of the material being operated upon. To
prevent damage to the material I apply the guide roller C which revolves in the
bearings D attached by any suitable ordinary means to the underside of the
knocking off board A. The material E having passed through the usual operations
in the machine is conveyed upwards as shown by arrow through the knocking
off board A, and in so doing is prevented by the roller () from coming in contact
with the back part F of the holes B, and so preventing any serious frictional
contact therewith, at the same time preventing the tearing or other damage
which frequently occurs to the material in passing through the knocking off
board A.
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
The arrangement, construction and application of guide roller C to the underside of
knocking off board of milling or fulling machines, substantially as and for purposes
herein set forth.
