I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
M.I.M.E., do hereby declare the nature of this invention to be as follows:-
The subject of this invention consists of a new method of alternately clothing
carding and other machines, and the means and apparatus employed therefor.
In ordinary card clothing with symmetrically arranged card teeth the wool, cotton
and other fibrous substances collect with difficulty between the teeth of the card and
us a result the fibrous material is what may be termed "rolled" and the carding is
performed in an incomplete manner between the two parts working in opposite
directions and which also mix the impurities of the carding band with the fibrous
substances. The parts of the fibrous material which become entangled in the card, can
only with difficulty be removed therefrom and suffer considerably by being torn and
converted into refuse to the loss of the spinner.
The card clothing as at present used for the carding of fibrous substances is provided
with teeth placed in regular order, and the number of teeth to the square inch is the
same over the total surface of the card band.
The new card clothings, styled "discontinuous " or
contrary, unequally distributed over any desired surface.
"undulatory" are, on the
This irregular arrangement can be of an order by which the number of teeth
diminishes regularly over a certain distance and to which arrangement is applied the
term "change" and which change is repeated in the same order or two neighbouring
changes may follow in the reverse order.
The length of a change on this card-clothing cannot be uniformly stated as it depends
entirely on the length of the fibre to be worked.
The advantages of this new card clothing are the following
:-
1. The wool, cotton or other fibrous substances find lodgment in the card-clothing
proper; the changes take place at regular intervals though with irregularly arranged
teeth, series of widely and closoly set teeth alternating with each other.
The different parts of a carding machine work in opposite directions with the result
that the fibrous substances leave all impurities in the widely set portions of the card
band, passing freely between these portions, and are then retained in the close parts of
the same card band from which they are finally drawn out by part of the card
mechanism working in the opposite direction, so that an effectual combing takes place.
The result thus obtained is extraordinary in comparison with the present system.
The wool, cotton or other fibrous substances are rendered perfectly clean by this treat-
ment being thoroughly worked up and combed and almost ready for immediate use.
2. The fibrous substances treated by the "discontinuous" card possess the great
advantage of not being worked in the card roughly, but lightly and smoothly carded
and combed, the fibres do not lose anything in their length but remain in perfect
order and enable the spinner to spin them, of the same raw material, one or several
counts finer a fact which is of great importance to the spinning industry.
3. The "discontinuous" card clothing produces less waste than the present form of
card clothing as the fibrous substance is not weakened or torn.
These considerable advantages have not been attained in the spinning industry with
the ordinary card clothing. The card clothing serves to cover different parts of a
carding machine, such as drums, combs, feeding and cleaning rollers, which in their
turn serve to card the wool, cotton, silk, hemp, jute and like fibrous substances.

page_text: These alternate wire card clothings can be used on any material according to
requirements.
The new card clothing is manufactured by means of a mechanical attachment such
as herein described by way of example.
This attachment is simply mounted upon an ordinary card setting machine for the
purpose of securing an irregular distribution of the points. To transform an ordinary
card setting or pointing machine into one of the new type, two catches are fixed on
the tooth wheel called the spring wheel which is of a very small and regular pitch, in
order to stop this wheel and control the movement of the whole apparatus, as the,
former may prove too fast and even turn at too great a velocity in a reverso
direction.
A second tooth-wheel is of an irregular pitch and connected to the former with the
object of producing a uniformily accelerated movement of the card-clothing. To the
pitch wheel is attached a disc or grooved wheel to push a pawl which when connected
with the ratchet wheel puts the whole apparatus in motion. This last named ratchet.
wheel of existing machines retains its original form in the new machines now being
described.
The pawl is so operated for example by a wedge lug as to drive the irregular pitched
wheel forward.
For manufacturing the card-clothing different appliances may be used.
The ordinary spring wheel has a regular pitch over the whole of its circumference.
The wheel which is added to produce the undulated and irregularly divided cards does.
not represent the immediate transition of the small pitch into the larger.

Improvements in or relating to Carding or Combing Machines.
A communication from GEORGES SORIVE, Manufacturer, of Lille, in the Republic of
France.
I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
M.I.M.E., 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:-
The subject of this invention consists of a new method of alternately clothing
carding and other machines, and the means and apparatus employed therefor.
In ordinary card clothing with symmetrically arranged card teeth, the wool cotton
and other fibrous substances collect with difficulty between the teeth of the card and
as a result the fibrous material is what may be termed "rolled" and the carding is
performed in an incomplete manner between the two parts working in opposito
directions and which also mix the impurities of the carding band with the fibrous
substances. The parts of the fibrous material which become entangled in the card,
can only with difficulty be removed therefrom and suffer considerably by being torn
and converted into refuse to the loss of the spinner.
The card clothing as at present used for the carding of fibrous substances is provided
with teeth placed in regular order, and the number of teeth to the square inch is the
same over the total surface of the card band.
The new card clothing styled "discontinuous" or "undulatory" are, on the contrary,
unequally distributed over any desired surface.
This irregular arrangement can be of an order by which the number of teeth
diminishes regularly over a certain distance and to which arrangement is applied the
term "change" and which change is repeated in the same order or two neighbouring
changes may follow in the reverse order.
The length of a change on this card clothing cannot be uniformly stated as it depends
entirely on the length of the fibre to be worked.

page_text: The advantanges of this new card clothing are the following
1. The wool cotton or other fibrous substances find lodgment in the card clothing
proper; the changes take place at regular intervals, though with irregularly arranged
teeth, series of widely and closely set teeth alternating with each other.
The different parts of a carding machine work in opposite directions with the result
that the fibrous substances leave all impurities in the widely set portions of the card
band, passing freely between these portions, and are then retained in the close parts of
the same card-band from which they are finally drawn out by part of the card
mechanism working in the opposite direction, so that an effectual combing takes
place.
The result thus obtained is extraordinary in comparison with the present system.
The wool, cotton or other fibrous substances are rendered perfectly clean by this
treatment being thoroughly worked up and combed and almost ready for imme-
diate use.
2. The fibrous substances treated by the "discontinuous" card possess the great
advantage of not being worked in the card roughly, but lightly and smoothly carded
and combed the fibres do not lose anything in their length but remain in perfect
order and enable the spinner to spin them, of the same raw material, one or several
counts finer a fact which is of great importance to the spinning industry.
3. The "discontinuous" card clothing produces less waste than the present form of
card clothing as the fibrous substance is not weakened or torn.
These considerable advantages have not been attained in the spinning industry with
the ordinary card-clothing. The card-clothing serves to cover different parts of a
carding machine, such as drums, feeding and cleaning rollers, which in their turn
serve to card the wool, cotton, silk, hemp, jute, and like fibrous substances.
These alternate wire card clothings can be used on any material according to
requirements.
In the accompanying drawings are represented several patterns of the improved
card clothing.
Fig. 1 shows a length of one form of card clothing made in the ordinary
manner and
Fig. 2 is a form of intermittent or graded card clothing.
Fig. 3 is another modification of card clothing presenting alternate shades or
undulations. This latter form of card clothing is founded as will be understood on
the same principle and obtained by practically the samo means of manufacture as the
form mentioned before.
Having now particularly described and ascertained the nature of the said inven-
tion as communicated to me by my foreign correspondent, and in what manner the
same is to be performned I declare that what 1 claim is :-
1. A card clothing differing from the ordinary card clothing by the variation in the
distance between the point rows substantially as described.
