Improvements in the Method of and Means for Mounting Card
Clothing on Carding Engine Cylinders.
I WILLIAM WALTON, of Haughton Dale, Denton, in the County of Lancaster,
Wire Card Manufacturer, do hereby declare the nature of this Invention to be as
follows:-
My invention relates to improvements in the method of and means for mounting
card clothing on carding engine cylinders.
In clothing a cylinder according to my Invention I propose to make the entire
clothing for the cylinder by preference in a single sheet and to unite the ends of this
sheet by stitching or otherwise so as to form an endless band of card clothing fitting
loosely over the cylinder. I have no card teeth for a short distance near each end of
the band so as to leave a transverse space extending right across the band. I form a
transverse groove in the cylinder, which I strengthen at this point, and 1 bring the
transverse space in the band of card clothing into a position above and corresponding
with this groove.
To stretch and secure the endless band of card clothing upon the cylinder, I employ
a tension bar or equivalent of suitable size and shape which is placed on the band in
the above mentioned space in the card teeth and is forced down into the groove in the
cylinder by screws or equivalents whereby the card clothing is drawn tight around the
surface of the cylinder.
Instead of having only a single groove as described, I may have more than one
groove with a corresponding number of spaces in the card teeth on the clothing and
employ as many adjustable tension bars as there are grooves and spaces; or I may
secure the ends of the band of card clothing to the cylinder on one side of it and have
the tightening device on the opposite side.
I have described my Invention as applied to a single sheet of card clothing but it
is obvious that the clothing might be made in say two pieces and two tightening
devices employed on opposite sides of the cylinder and also that the tightening device
of tension bar, groove and screws might in a similar manner be advantageously applied
to stretch and tighten up rings or endless bands of card fillet.

1, WILLIAM WALTON, of Haughton Dale, Denton in the County of Lancaster, Wire
Card 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 :-
My invention relates to improvements in the method of and means for mounting card
clothing on carding engine cylinders.
In clothing a cylinder according to my invention I may make the entire clothing
for the cylinder in a single sheet and unite the ends of this sheet by stitching or other-
wise so as to form an endless band of card clothing fitting loosely over the cylinder.

employ as many adjustable tension bars as there are grooves and spaces; or I may
secure the ends of the band of card clothing to the cylinder on one side of it and have
the tightening device on the opposite side.
I have described my invention as applied to a single sheet of card clothing but it is
obvious that the clothing might be made in say two pieces and two tightening devices
employed on opposite sides of the cylinder and also that the tightening device of
tension bar groove and screws might in a similar manner be advantageously applied to
stretch and tighten up rings or endless bands of card fillet.
And in order that my invention may be fully understood and readily carried into
effect I will describe the accompanying two Sheets of Drawings reference being had
to the figures and letters marked thereon.
Fig. I is an end view of a carding engine cylinder to which my invention is applied
and Fig. 2 is a side view of part of the same partly in section. Fig. 3 is a similar
view to Fig. 2 showing the cylinder partly clothed with narrow bands of card fillet
and Fig. 4 is an enlarged sectional view of a tension device.
Similar letters refer to similar parts throughout the several views.
a is the card clothing made in this instance in a single sheet united at the ends
which are devoid of teeth by stitching or otherwise; b is the shell of the card cylinder
which is strengthened at c where it is grooved from one end of the cylinder to the
other to receive the tension bar e the continuous sheet of card clothing is placed on the
cylinder with the stitched blank part of the sheet immediately over the groove the
tension bar e is then placed on the blank part of the sheet of card clothing and drawn
into the groove by screws thus tightening the card clothing on the cylinder and
holding it securely in its place.
In place of uniting the ends of the sheet of card clothing by stitching or otherwise
previous to securing it on the carding engine cylinder the ends of the sheet may be
tacked on to plugs g let into the cylinder or otherwise secured the tension bar e being
employed to tighten the card clothing as before.
The cylinder may be balanced by casting a rib opposite to the tension bar.
Fig. 3 is a side view of part of a card cylinder clothed with card fillet according to
my invention; in this case the fillet is cut into lengths equal to the circumference of
the cylinder both the ends of the card fillet are then brought together and tacked or
otherwise secured to one side of the cylinder; at the opposite side is formed a
before described and over each strip of fillet a¹ is placed a short tension bar el
screwed to the cylinder and by which the ring of fillet is tightened. The strips of
card fillet have or may have blank spaces where the tension bars press on them.
as
Frolich is
Although I have shown and described a single groove for a tension bar or bars
it is obvious that any number of grooves and bars might be used and other means
than those described employed for securing the tension bar or bars to the cylinder.
By the use of my invention when the card cylinder is clothed with bands of
card fillet it is a simple matter to replace any band in case of damage or accident
and further the tension on the bands or sheets of clothing can be regulated at will.
This invention may also be, applied for tightening sheets or filletting covered
with emery on, rollers. for grinding wire. card clothing.

page_text: Having now particularly described and ascertained the nature of this said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
1. The improved method of and means for mounting card clothing on carding
engine cylinders substantially as and for the purposes herein described and as
shown on the annexed Drawings.
2. Securing and tightening card clothing on the cylinder of a carding engine
by means of a tension bar or bars with screws or their equivalents in combination
with a groove or grooves.
