Year: 1878

page_text: LETTERS PATENT to James Taylor, of Hawick, Roxburghshire, North Britain,
and Samuel Tovey Rawlings, of Frome, in the County of Somerset, for the
Invention of "IMPROVEMENTS IN CARDS FOR CARDING FIBROUS MATERIALS."
Sealed the 1st November 1878, and dated the 16th May 1878.
PROVISIONAL SPECIFICATION left by the said James Taylor and Samuel
Tovey Rawlings at the Office of the Commissioners of Patents on the 16th May
1878.
JAMES TAYLOR, of Hawick, Roxburghshire, North Britain, and SAMUEL TOVEY
RAWLINGS, of Frome, in the County of Somerset. "IMPROVEMENTS IN CARDS
FOR CARDING FIBROUS MATERIALS."
The object of this Invention is to produce cards for carding engines, whoreby
"cleaning" and "grinding" are in a great measure dispensed with, and a saving in
the wool is effected.
The Invention refers to the employment in cards of a strip or strips of filletting
composed of staples or wires inserted in material such as leather, cloth, or other
suitable material in such manner that the said staples or wires are caused to project
somewhat beyond the ordinary carding surface.
The staples or wires may be made of round shaped or flattened wire, and if
desired of hardened steel.
The "stripper" and "fancy" " of the carding engine is, according to our Inven-
tion, covered with strips of filletting, and in putting the same on it is wound
spirally, but with sufficient space between the spirals for the reception of the other
strip of fillet with the higher staples or wires; or we leave a space on the card for
the reception of the second fillet, and such space may be left in any position found
most suitable for the work to be performed.

page_text: In the working, the projecting wires aforesaid work into the workers and
cylinders of the carding engine, thereby preventing an accumulation of dirt, which
has hitherto occurred in engines as heretofore constructed, while at the same time
the cards of the said workers and strippers are kept sharp.

SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said James Taylor and Samuel Tovey Rawlings in the Great Seal Patent
Office on the 16th November 1878.
JAMES TAYLOR, of Hawick, Roxburgshire, North Britain, and SAMuel Tovey
RAWLINGS, of Frome, in the County of Somerset. "IMPROVEMENTS IN CARDS FOR
CARDING FIBROUS MATERIALS."
The object of this Invention is to produce cards for carding engines, whereby
cleaning" and "grinding" are in a great measure dispensed with, and a saving in
the wool is effected.
The Invention refers to the employment in cards of a strip or strips of filleting
composed of staples or wires inserted in material such as leather, cloth, or other
suitable material in such manner that the said staples or wires are caused to project
somewhat beyond the ordinary carding surface.
The staples or wires may be, made of round shaped or flattened wire, and if
desired of hardened steel.
The stripper and fancy of the carding engine is, according to our Inven-
tion, covered with strips of filleting, and in putting the same on it is wound
spirally, but with sufficient space between the spirals for the reception of the other
strip of fillet with the higher staples or wires; or we leave a space on the card for
the reception of the second fillet, and such space may be left in any position found
most suitable for the work to be performed.
In the working, the projecting wires aforesaid work into the workers and
cylinders of the carding engines, thereby preventing an accumulation of dirt, which
has hitherto occured in engines as heretofore constructed, while at the same time
the cards of the said workers and cylinders are kept sharp.
And in order that the Invention may be more fully understood, reference is given
to the accompanying Sheet of Drawings.
Figure 1 is a front elevation of a stripper roller of a carding engine showing
our Invention applied thereto; Figure 2 is longitudinal section of the same;
Figure 3 shows a stripper roller without the filleting; and Figure 4 shows a
piece of the filetting detached.
a, a, are the strips of filleting; b, b, the spaces, in which the filetting is laid,
formed on the roller in a spiral form, and in which spaces the filetting is wound
and secured at one end by a button and loop or other convenient means.
The staples of the filetting are seen to project beyond the cards proper.
We have in the Drawings somewhat exaggerated the extent of the projections

page_text: in order that they may be clearly seen, but in practice the extent of projection is
preferably not so great as would appear from the Drawing, but at the same time
we do not limit ourselves to any height of the projections of the staples; or instend
of putting in the filetting in separate strips, as shown at Figure 1, the projecting
staples made according to our Invention may be inserted directly into the founda-
tion of the ordinary card, or in other words, into the space indicated by the
spirals in Figure 3; or the space may be formed by cutting the wires out of the
ordinary card, or by pressing them down in a spiral form, and inserting the strips
of filletting or "slip" in their place.
The strips of filletting or "slip" may be applied to sheet or leaf cards by forming
a diagonal space therein by cutting or withdrawing or pressing down the ordinary
staples for the reception thereof; or the ordinary staples may be withdrawn in a
diagonal direction, and the projecting wires may be inserted in the same foundation
as the ordinary staples.
The Invention is equally applicable (although not shown in the Drawings) to
the "fancy" and angle stripper rollers.
Having now described the nature of the said Invention, and in what manner tho
same is to be performed, we declare that we are aware that attempts have been
made to produce carding rollers with wires of varying length, that is, wheroin tho
wires are not all of uniform longth; we are also aware that it has been proposed
to attach longitudinal strips of cards at intervals, the intervening parts or spaces
being without cards or carding surfaces, we therefore lay no claim to any such
arrangements, but we do claim as our improvements in cards for carding fibrous
materials, the employment in fancies strippers, angle strippers, and such other
rollers of carding engines as may be desirable, of staples, wires, or filletting placed
on or inserted in the foundation of the ordinary card in a spiral direction in com-
bination with and projecting beyond the ordinary carding surface, substantially in
manner and for the purposes set forth.
In witness whereof, I, the said Samuel Tovey Rawlings, for myself and on
behalf of the said James Taylor, have hereunto set my hand and seal, this
First day of November, in the year of our Lord One thousand eight hundred
and seventy-eight.
Signed, sealed, and delivered by
the before-named Samuel Tovey
Rawlings, in the presence of

Solicitor,
