A NEW OR IMPROVED APPARATUS FOR DIVIDING THE CARD COVERED SURFACES OF THE DRUMS OF CARDING MACHINES
Year: 1880

page_text: LETTERS PATENT to Pierre Pingard, of La Claire, in the Republic of
.
France, for an Invention of "A NEW OR IMPROVED APPARATUS FOR
DIVIDING THE CARD COVERED SURFACES OF THE DRUMS OF CARDING
MACHINES."
PROVISIONAL SPECIFICATION left by the said Pierre Pingard at the Office
of the Commissioners of Patents on the 4th December 1880.
PIERRE PINGARD, of La Claire, in the Republic of France.
"A NEW
OR IMPROVED APPARATUS FOR DIVIDING THE CARD COVERED SURFACES OF THE
DRUMS OF CARDING MACHINES."
In order to obtain regular threads or fibres various arrangements of cards are
used; that most usually employed is a carding drum divided into strips. When
these strips are not of regular width, or when the rings prepared by the card
manufacturer, although regular themselves, are not fixed quite regularly, or the
leather becomes distorted under the influence of temperature, only irregular or
broken threads are obtained.
By means of the apparatus forming the subject of this Invention a strip of
card-cloth can easily be prepared from the card sheet.
The apparatus consists of a rectangular prismatic bar of wood or iron of
suitable dimensions. If the said bar be made of wood the upper surface and both
sides are covered with iron plates.
A shaped slide clasps the bar on three sides and is adapted to slide to and fro
thereon and to be fixed in any required position by the means of a screw. A
fixed guide cheek is either fastened to or cast in one piece with this slide.
A moveable guide cheek is furnished with elongated holes to admit of its being
adjusted nearer to or further from the fixed cheek by means of set screws, whereby
the space between the two cheeks may be regulated to suit the thickness of a steel
tool, which cuts or tears the wires of the card-cloth to the desired width. These
tools are of various thicknesses according to circumstances, generally from 2 to 20

page_text: millimetres, a special tool being requisite for each width. The tool is kept down
by a moveable plate, which is secured by screws, so that the said tool can only be
moved backwards and forwards lengthwise.
The Ushaped slide may, if preferred, be moved by means of a traversing screw
in the bar in a manner similar to that employed for the slide rest of a lathe.
The apparatus is used by securing the bar parallel to the circumference of the
card covered drum, the steel tool crushing or breaking out the card wires where
required.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Pierre Pingard in the Great Seal Patent Office on the 31st May
1881.
PIERRE PINGARD, resident at La Chaire, in the Republic of France. " A NEW
OR IMPROVED APPARATUS FOR DIVIDING THE CARD COVERED SURFACES OF THE
DRUMS OF CARDING MACHINES."
In order to obtain regular threads or fibres various arrangements of cards are
used; that most usually employed is a carding drum divided into strips. When
these strips are not of regular width, or when the rings prepared by the card
manufacturer, although regular themselves, are not fixed quite regularly, or the
leather becomes distorted under the influence of temperature, only irregular or
broken threads are obtained.
By means of the apparatus forming the subject of this Invention a strip of card
cloth can easily be prepared from the card sheet.
The apparatus, as shewn in the Drawings, consists of a rectangular prismatic
bar a of wood or iron of suitable dimensions. If the said bar be made of wood
the upper surface and both sides are covered with iron plates.
The Ushaped slide 6 clasps the bar a on three sides and is adapted to slide to
and fro thereon and to be fixed in any required position by means of the
screw h.
The fixed guide cheek c is either fastened to or cast in one piece with the
slide b.
The moveable guide cheek d is furnished with elongated holes to admit of its
being adjusted nearer to or further from the cheek c by means of the set screws i,
whereby the space between the cheeks c and d may be regulated to suit the
thickness of the steel tool e, which cuts or tears the wires of the card cloth to the
desired width. These tools are of various thicknesses according to circumstances,
generally from 2 to 20 millimetres, a special tool being requisite for each width.
The tool is kept down by a moveable plate f, which is secured by the screws i, i,.
so that the said tool can only be moved backwards and forwards lengthwise.
The slide 6 may, if preferred, be moved by means of a traversing screw in the.
bar a in a manner similar to that employed for the slide rest of a lathe.

Having now described the nature of the said Invention, and the manner in
which the same is to or may be performed, I would have it understood that what
I claim is,―
.
The combination of the bar a, the slide b, the guide cheeks c and d, the plate f
and the tool e, comprising the apparatus for dividing the circumference of carding
drums when covered with sheet card cloth, as herein before described and illustrated
in the Drawings.
In witness whereof, I, the said Pierre Pingard, have hereunto set my hand
and seal, this Twenty third day of May, in the year of our Lord One
thousand eight hundred and eighty one.
