ARMITAGE HAIGH, of the Firm of John Haigh and Sons, of Huddersfield, in the
County of York, Machine Makers, and GEORGE MILNES, of the same Place, Scribbler
and Wool Extractor. "IMPROVEMENTS IN THE METHOD OF AND APPARATUS FOR
WORKING CARDS."
The object of our Invention is to arrange the cards used in connection with
doffers, workers, and other rollers and cylinders in such a manner as to obtain a
larger amount of "working surface" on the cards than has hitherto been possible.
Hitherto cards have been fixed to cylindrical rollers, and in order to obtain a large
amount of "working surface" this has necessitated the use of large doffer cylinders
and other rollers and cylinders. But by means of the largest cylinders and rollers
now in use it is possible to obtain only a small amount of "working surface." We
accomplish our object in the following manner:-We take a sheet of card of the
required length and breadth, and having joined the ends of the same, so as to form
a loose endless card, we cause the same to travel by means of two or more rollers
(varying in number according to the number of positions in which the card is
required to be worked) placed inside the card. These rollers have bearings and
setting screws attached in order to regulate the tension of the sheet, and are fixed
to the carding machine in such positions as may be necessary to place the card in
work. We actuate the rollers by means of gearing or belting in the ordinary
manner. By these means the portion of the card which at any moment is above
any two rollers, and passing from one of these rollers to the other, has a straight
and not a circular surface, thereby enabling us to get a larger amount of "working
surface," and thus to preserve the length of the staple of the material to be carded,
to keep the cards cleaner, and to work the cards in a smaller space than by the
method hitherto adopted.

The object of our Invention is to arrange the cards used in connection with
doffers, workers, and other rollers and cylinders in such a manner as to obtain a
larger amount of "working surface on the cards than has hitherto been possible.
Hitherto cards have been fixed to cylindrical rollers, and in order to obtain a
large amount of "working surface" this has necessitated the use of large doffer
cylinders and other rollers and cylinders. But by means of the largest cylinders
and rollers now in use it is possible to obtain only a small amount of "working
surface."
We accomplish our object in the following manner-We take a sheet of card of
the required length and breadth, and having joined the ends of the same, so as to
form a loose endless card, we cause the same to travel by means of two or more
rollers (varying in number according to the number of positions in which the card
is required to be worked) placed inside the card. These rollers have bearings and
setting screws attached to them in order to regulate the tension of the sheet, and
are fixed to the carding machine in such positions as may be necessary to place
the card in work. We actuate the rollers by means of gearing or belting in the
ordinary manner. By these incans the portion of the card which at any time is
above any two rollers and passing from one of these rollers to the other has a
straight and not a circular surface, thereby enabling us to get a larger amount of
working surface, and thus to preserve the length of the staple of the material to be
carded, to keep the cards cleaner, and to work the cards in a smaller space than by
the method hitherto adopted.
Having thus described our said improvements, and the means we are acquainted
with for carrying the same into effect, we would have it understood that we do not
confine ourselves to the precise details described, as these may be varied without
departing from the character of our Invention, but what we believe to be novel and
original, and what we claim as the Invention secured to us by the hereinbefore in
part recited Letters Patent is,―
The use of the loose endless card, and the use of the two or more rollers, sub-
stantially in the manner and for the purpose as described.
In witness whereof, we, the said Armitage Haigh and George Milnes, have
hereunto set our hands and seals, this Sixth day of January, One thousand
sicht hundred and nights

presence of
