PROVISIONAL SPECIFICATION.
Improvements in Machines for Grinding Card Clothing.
I, WILLIAM NOTON, 93, Windsor Road, Oldham, in the County of Lancaster,
Cotton Spinner, do hereby declare the nature of this invention to be as follows:-
This invention relates more particularly to means for gradually and automatically
inserting the emery disc or discs between the teeth of the card clothing to be
ground so as to produce a better result as regards smoothness and shape of the
teeth.
According to one form of my invention I suitably move the teeth of the card
clothing between the emery disc or discs instead of vice versa. The card clothing
may be mounted on a cylinder or other suitable support as in the case of a flat
grinding machine, and such cylinder or support moved vertically, laterally or
diagonally against emery disc or discs by means of suitable gearing, screws, levers,
cams, or equivalent motions.
According to another form of my invention I may arrange the card clothing as
well as the emery disc or discs to move simultaneously into and out of each other
and thus effect a gradual and automatic insertion of both teeth and disc.

COMPLETE SPECIFICATION.
Improvements in Machines for Grinding 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 :-
This invention relates more particularly to means, such as described in Letters
Patent No. 9817* dated May 24th 1892, granted to me, for gradually and
automatically inserting the emery disc or discs between the teeth of the card
clothing to be ground so as to produce a better result as regards smoothness and
shape of the teeth.
And in order that my invention may be more fully understood I have caused to
be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures,
Figs. 1, 3, 4, 5 & 6, being side views and Fig. 2 a sectional end view of Fig. 1,
of a portion of a card clothing grinding machine showing my improvements
applied.
Referring to Figs. 1, 2, 3, 4 & 5, according to one form of my invention I suitably
move the teeth of the card clothing a between the emery disc or discs b instead of
vice versa. The card clothing a may be mounted on a cylinder c or other suitable
support, as in the case of a flat grinding machine, and such cylinder or support c
moved automatically vertically, laterally or diagonally against the emery disc or
discs b.
Referring to Fig. 6, according to another form of my invention, I may arrange
the teeth of the card clothing a, as well as the emery disc or discs b, to move
simultaneously to and from each other and thus effect a gradual and automatic
insertion of both the said teeth and discs.
In each of the above cases, the cylinder or card clothing support c may be moved,

page_text: as shown in Figs. 1, 2, 3 & 6, by two screws d which carry the movable bearings c
of the cylinder or support shaft 7 and are each geared up to a short shaft e on which
is fixed a ratchet wheelf, operated by a pawl f' carried by a lever g, which by
means of a rod is connected to another lever i operated upon by a cam k fixed on
the cylinder or support shaft l.
c¹
In lieu of screws d, the bearings c' may be carried by movable shanks n, see
Fig. 4, the lower end of each shank resting on the one end of a lever m, whilst the
other end is operated upon by a cam k fixed on the short shaft e, having also a
ratchet wheel, or the cam k may be arranged to support and actuate the shank n
of the cylinder or support bearing directly, as shown in Fig. 5, the ratchet
wheel in each case may be operated as previously described.
When moving both the cylinder or support c and the grinding disc or discs to
or from each other, as shown in Fig. 6, the cylinder or support c, may be raised or
lowered similarly as shown in Figs. 1, 2, 3, 4, & 5, whilst the grinding disc or discs b
may be raised or lowered as described in my Patent herein before referred to.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim, is-
1st. In machines for grinding the teeth of card clothing, the application of a
suitable motion adapted to move the cylinder or support e carrying the card clothing
to be ground to and from the grinding disc or discs 6 for the purpose of gradually
aud automatically inserting the teeth of the card clothing between the grinding disc
or discs b, substantially as set forth.
2nd. In machines for grinding the teeth of card clothing, in which the cylinder
or support c carrying the card clothing is rendered movable to and from the emery
disc or discs b, the application of a suitable motion adapted to raise or lower the
grinding disc or discs 6 and thus cause the cylinder or support c and the grinding
disc or discs b to move simultaneously, to and from each other for the purpose of
gradually and automatically inserting the teeth of the card clothing and the emery
disc or discs b between each other, substantially as set forth.
Dated this 10th day of July 1893.
