Improvements in the Grinding of Card Clothing.
WILLIAM NOTON 93 Windsor Road Oldham in the County of Lancaster
Cotton Spinner. I do hereby declare the nature of this invention to be as follows:-
My invention relates to the grinding of card clothing and consists in changing
the direction or revolution of the cylinder on which the card clothing is wound for
grinding. The clothing being wound on in a spiral fashion, the grinding discs are
made to traverse across at a speed proportionate, so as to keep the grinding discs
in the same or as nearly as possible the same groves, by reversing the cylinder the
same result is obtained in returning. This I accomplish by driving the cylinder
with an open and cross strap alternately or by bevels or other geering being
thrown in and out of gear alternately.

COMPLETE SPECIFICATION.
Improvements in the Grinding of Card Clothing.
I, WILLIAM NOTON, of 93, Windsor Road, Oldham, in the County of Lancaster,
Cotton Spinner, 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 grinding of card clothing and consists in changing
the direction or revolution of the cylinder on which the cards are wound for
grinding.
The clothing being wound on in a spiral fashion the grinding discs are made to
traverse across at a speed proportionate so as to keep the grinding discs in the same
or as nearly as possible the same grooves. By reversing the cylinder the same
result is obtained in returning.
This I accomplish by driving the said cylinder with an open and cross strap
alternately, or by bevel or other gearing being thrown in and out of gear
alternately.
And in order that my invention may be more fully understood I have caused to
be appended hereunto one sheet of drawings showing how the same may be carried
out in various ways.
a is the cylinder upon which the card clothing & to be ground is wound, c are the
grinding disc or discs which traverse across the card clothing on the cylinder a,
d is the side frame, e an existing form of driving gear.
According to one form of my invention and referring to Fig. 1, I cause the
direction or revolution of the cylinder a to be reversed upon the arrival of the
grinding disc or discs e at either end of the cylinder a by the application of an
open and crossed strap motion to the existing or other suitable driving gear e
of the cylinder a, or by the application of bevel or other wheels y adapted to be
thrown in and out of gear, or rendered alternately inoperative by suitable means,
as shown in Fig. 2.
The said reversing motion or gear is or may be automatically operated through
suitable connections, for instance, from the part which causes the emery disc or
discs e to traverse across the cylinder a, as shown in Fig. 1.
It will be evident that in lieu of employing the said reversing motion or gear, as
[ Price 8d 1

page_text: shown in the drawing, the same may be employed overhead, either on the line or on
a separate shaft.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I wish it to be understood
that I do not confine myself to the particular construction of the reversing motion
or gear aforesaid nor the particular method of employing the same in connection
with a card cloth grinding machine, but what I claim, is-
-
In card cloth grinding machines in which the card clothing to be ground is wound
upon a rotating cylinder, the employment of a suitable reversing motion or gear,
adapted to reverse the direction or revolution of the said cylinder at each end of
the traverse of the grinding disc or discs for the purpose of preventing damage to
the teeth of the card clothing on the return of the said emery disc or discs,
substantially as set forth.
Dated this 25th day of April 1893.
