Improvements relating to 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 of an
arrangement for the grinding of the teeth of the same by what is known as
side grinding, and consists of an automatic arrangement for gradually inserting
the emery disc or discs between the teeth of the card for grinding. This has
hitherto been done by hand setting. By my arrangement I gradually enter or
rise the grinding disc or discs among the teeth, preferably beginning at the top, and
by another arrangement prevent the disc or discs descending beyond a certain
depth. To do this I connect the present wheels which are worked by hand for setting,
with an additional shaft on which I have a ratchet wheel, that is operated by the
traversing Horsfall apparatus, or grinding roller, so as to give one or more teeth as
required. I also make a ratchet wheel with a space without teeth, so as to stop
when a certain depth is attained. I accomplish the same result by a slow regular
motion such as a screw, the same to be thrown out of gear when required by a
clutch box or an equivalent to accomplish the same purpose. Instead of the above
I get the same effect by raising or lowering the grinding disc or discs by means of
levers operated by an excentric, or heart motion, or inclined plane, or a crank motion
whether as a pin on a wheel or otherwise.

Improvements relating to the Grinding of Card Clothing.
.i
:
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 means for the grinding of teeth of card clothing, what is
known as side grinding and consists of an automatic arrangement for gradually
inserting the emery disc or discs between the teeth of the card clothing in grinding
the same.
By my arrangement I gradually enter or rise the grinding disc or discs among
the teeth, preferably beginning at the top and by another arrangement prevent the
disc or discs descending beyond a certain depth.
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.

page_text: Fig. 1 is a side view and Fig. 2 an end view of the respective portion of a card
cloth grinding machine, provided with one form of my invention.
Figs. 3, 4 & 6 are detached side views showing various modifications thereof and
Fig. 5 an end view of Fig. 4.
a is the cylinder, on which the card clothing is wound, 6 the side frame, c are the
emery disc or discs, d the "Horsfall" traversing apparatus or grinding roller, e the
segment which carrys the emery disc or discs c and gears into a pinion e¹, mounted
on a shaft carrying at the back another segment g, which gears into a worm g',
mounted on a short shaft h, furnished with a handle ', the shaft & also carrying a
pinion gearing into a stop wheel, which parts broadly speaking constitutes an
ordinary card cloth grinding machine as heretofore has been in use.
In carrying out my invention and referring to Figs. 1 & 2, according to one form
of my improvements, I connect the present wheels i, which are worked by the
handle for setting, by means of a pinion with an additional shaft 7 on which I
have a ratchet wheel m that is operated from the traversing "Horsfall" apparatus
or a grinding roller d, by means of a cam n and pawl lever n' so as to give one or
more teeth as required, during each revolution of the "Horsfall traversing
apparatus or grinding roller d and thus lower the grinding disc or discs e gradually
and automatically through the gearing aforesaid. may also make the ratchet
wheel m with a space m' without teeth, as shown in Fig. 3, so as to stop its rotation
when a certain depth of the grinding disc or discs c is attained. The same result
"
may be accomplished by a slow regular motion, such as a screw o, shown in Figs. 4
& 5, the same to be thrown out of gear when required by a clutch box p or an
equivalent arrangement.
Instead of the above I get the same effect by raising or lowering the grinding
disc or discs c by means of levers 9, see Fig. 6, operated by an eccentric q', heart
motion or incline plane or a crank motion whether as a pin in a wheel or otherwise,
as will be well understood.
The improvements described may also be applied to what is known as a flat
grinding machine as will be readily understood.
By gradually lowering the disc or discs c between the card teeth I prevent
damage to the card and obtain a smoother tooth with a slight taper, which
facilitates the stripping of the card greatly and dispenses with the plough sometimes
used.
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-
In a machine for grinding the teeth of card clothing, the application of a suitable
motion such as gearing, levers, cams, screws, or their equivalent, actuated from any
moving part of the said machine; for the purpose of gradually and automatically
inserting and lowering or raising the grinding disc or discs between the teeth of the
card clothing in lieu of by hand, substantially as set forth.
Dated this 27th day of Sentember 1892.
