page_text: LETTERS PATENT to John Thornton, of Cleckheaton, in the County of York,
Machine Tool Maker, for the Invention of "IMPROVEMENTS IN MACHINERY
FOR CARDING FIBRES, AND IN FIBRE WASTE MACHINES."
PROVISIONAL SPECIFICATION left by the said John Thornton at the Office
of the Commissioners of Patents on the 21st March 1878.
JOHN THORNTON, of Cleckheaton, in the County of York, Machine Tool
Maker. "IMPROVEMENTS IN MACHINERY FOR CARDING FIBRES, AND IN FIBRE
WASTE MACHINES."
This Invention relates,―
Firstly. To improved construction of metallic cards, whereby an increased number
of cards or teeth inay be introduced and used within a given space.
Secondly. To improved means of securing the metallic cards or teeth used on
"burr rollers," "lickers in," "swifts," "workers," and other rollers.
22
"
Thirdly. The Invention relates to improvements for operating the "burr roller
and the "licker in," or other rollers, in such manner as to release or separate the
"
burrs or impurities from the wool or other fibre being operated upon. In the
use of metallic cards the object of this Invention is the construction and arrange-
ment of such cards that an increased number of cards or teeth may be within a
given distance or width. I construct such cards of L form, the base line being
rolled or formed to a feather edge, or reduced at its outer edge to an acute angle.
In applying the cards the base or horizontal limb of the L is wrapped over or upon
itself, so as to bring the teeth close together. A modification consists of a combina-
tion of cards and inverted T cards, the latter being introduced between the
lines of L cards, so as to obtain more points or teeth within a given distance.
Another modification being by the use of a combination of short T card and long
T cards, the base 1 of the short T* resting upon the base of each line-of T cards
upon each of its sides.
According to this Invention in securing the metallic teeth I employ one groove

page_text: cut or formed in the periphery of the roller of such width as to contain two lines or
strips of metallic teeth. The teeth of each strip being spaced by means of a rib
formed on the side of each strip. Other grooves and other strips being so
employed admits of the use of more teeth within a given length of roller than
lieretofore.
For the purpose of separating the "burra," knots, and dirt from the wool or fibre
heing operated upon, 1 impart to the burr roller and to the licker in a lateral
motion in addition to its rotary motion, so as to rub out the burr and refuse. Or in
lieu of such lateral motion, I apply the cards or teeth to such rollers spirally, or
otherwise so arranged on the periphery to give a "to-and-fro" or rubbing motion,
for purpose aforesaid.

JOHN THORNTON, of Cleckheaton, in the County of York, Machine and Tool
Maker. "IMPROVEMENTS IN MACHINERY FOR CARDING FIBRES, AND IN FIBRE
WASTE MACHINES."
This Invention relates,-
Firstly. To improved construction of metallic cards, whereby an increased number
of cards or teeth may be introduced and used within a given space.
Secondly. To improved means of securing the metallic cards or teeth used in
"burr rollers," "lickers in," "swifts," "workers," cotton gins, and other rollers.
Thirdly. In the use of metallic cards the object of this Invention is the con-
struction and arrangement of such cards that an increased number of cards or teeth
may be arranged within a given distanco in width. I construct such cards of L
form, the base line being rolled or formed to a feather edge, or reduced at its outer
edge to an obtuse angle. In applying the cards the base or horizontal limb of the
Lis wrapped over or upon itself, so as to bring the teeth close together.. A. modi-
fication consists of a combination of L cards and inverted T cards, the latter being
introduced (1) between the lines of L cards, so as to obtain more points or teeth
within a given distance. Another modification being by the use of a combination
of short cards and long T cards inverted, the baso 1 of the short Ts resting upon
the base of each line of long T cards upon each of its sides.
Fourthly. According to this Invention in securing the metallic tooth I employ
one grooove cut or formed in the periphery of the roller of each width as to contain
two lines or strips of metallic teeth, such teeth being right and left hand, the teeth
of each strip being spaced by means of a rib formed on the side of each strip.
Other grooves and other stripes being so employed admit of the use of more teeth
within a given length of roller than heretofore.
Fifthly. For separating the "burrs," knots, and dirt from the wool or fibre, I
apply the cards or teeth to rollers spirally or otherwise so arranged on the
periphery to give a "to-and-fro” or rubbing motion, for purpose aforesaid.

page_text: Such being the nature and object of this my said Invention, I will now proceed
to describe the same in detail, and in order that the Invention may be clearly under-
stood I have hereunto annexed two Sheets of Drawings, in which,-
Fig. 1 shews arrangement of ring groove A, and right and left hand teeth B
and C.
Fig. 2, view of groove, the teeth Band C being continuous, and groove A spirally
continued around the roller.
Fig. 3 is view of continuous teeth and groove, the latter being, as shewn,
arranged so as on rotation of the burr roller to give a lateral surface motion, so as
to release and separate the "burrs" or impurities of the fibre.
Fig. 4 is view of L teeth with base line, rolled or formed to a feathered
edge. The base of one line of teeth overlaps the base of the other, whether applied-
separately, or in rings, or in continuous spiral order. This form of wire gives great
strength at the angle of the vertical and horizontal lines of the L, and the wire is
formed by rolling to the form desired, and may also be applied without overlapping.
Figs. 5 and 6, shew the construction and order of arrangement of L and inverted
T teeth and long and short inverted T teeth.
Fig. 7 is an enlarged view of teeth, the working face or edge of which is rounded,
or the rough edge removed, so as to give a smoother working surface, and prevent
the cutting of the fibre, and also facilitates stripping the fibre therefrom.
Figs. 8 and 9 are enlarged sections of tooth.
Having thus fully described the nature and particulars of this my said
Invention, together with a nanner in which the same is to be performed, or
carried into practical effect, I would have it understood that I claim as my In-
vention,―
Firstly. The combination of strips of teeth and grooves, shewn by Figs. 1, 2, and 3,
and herein described.
Secondly. The combination and arrangement of teeth, as shewn by Fig. 4, and
herein described.
Thirdly. The combination of Land inverted T teeth, shewn at Fig. 5, and herein
described.
Fourthly. The combination of short T and long T teeth, shewn at Fig. 6, and
herein described.
Lastly. The construction of teeth, as illustrated by Figs. 7, 8, and 9, and herein
described.
In witness whereof the said John Thornton hath hereunto set his hand and
seal, this Sixteenth day of September, in the year of our Lord One thousand
eight hundred and seventy-eight.
