IMPROVEMENTS IN THE METHOD OF AND APPARATUS FOR MAKING CARDS."
Year: 1881

page_text: LETTERS PATENT to Joseph Sellers, of Scholes, near Cleckheaton, in the
County of York, Card Manufacturer, for an Invention of " IMPROVEMENTS IN
THE METHOD OF AND APPARATUS FOR MAKING CARDS."
PROVISIONAL SPECIFICATION left by the said Joseph Sellers at the Offico
of the Commissioners of Patents on the 23rd September 1881.
JOSEPH SELLERS, of Scholes, near Cleckheaton, in the County of York, Card
Manufacturer. "IMPROVEMENTS IN THE METHOD OF AND APPARATUS FOR
MAKING CARDS."
The object of this Invention is to arrange an ordinary card setting machino in
such a manner that I am enabled to produco cards having two bends between the
crown and point of each tooth, thus giving to the teeth more elasticity than is
obtained by cards of the ordinary construction, and producing a card suitable for
raising the nap on cloth or plush fabrics.
This I accomplish in the following manner:-In place of the ordinary crookers
I substitute a perforated plate which is raised by the ordinary crooker lever, until
the top of the perforation is above the line of teeth that are being set. Directly a
tooth is inserted in the foundation this plate is lowered, and forms the first bend
over the ordinary back head bar; the tooth is then driven home in the foundation,
when a bar actuated by a lever in connection with the tappet shaft is raised to
such a height that a slight bend is given to the tooth; and whilst this last named
bar is in contact with the tooth, the top of the perforated plate is pressed against
the tooth on the other side of the foundation, and completes the second bend, thus
producing a card, the teeth of which have two bends between the point and crown.

Manufacturer. "IMPROVEMENTS IN THE METHOD OF AND APPARATUS
MAKING CARDS.”
FOR
The object of this Invention is to arrange an ordinary card setting machine in
such a manner that I am enabled to produce cards having two bends between the
crown and point of each tooth, thus giving to the teeth more elasticity than is
obtained by cards of the ordinary construction, and producing a card suitable for
raising the "nap" on cloth and plush fabrics.
The Invention consists in substituting in place of the ordinary "crookers," a
plate having a perforation therein in the middle, which is actuated by the ordinary
crooked lever, and is arranged so that when a tooth is being inserted in the
foundation, the perforated portion of the plate is opposite to the said tooth, the
ends of the tooth passing over the back head bar into the perforated space of the
plate, which on being lowered, bends the tooth over the said bar. The tooth is
then driven home. in the foundation, when a bar on the opposite side of the
foundation to that on which is the perforated plate, rises against the crown of the
tooth, and supports the same, whilst the second bend is given to the tooth which
is effected by the rising of the perforated plate, the top edge of which, pressing
against the tooth, bends the same in the direction required.
In the accompanying Drawings, Figure 1 represents a sectional elevation of such
portions of a card setting machine as are required to illustrate my Invention.
Figure 2 is a plan of the carriage of a card setting machine with my improvements
applied; Figuro 3 is an enlarged detailed elevation of the perforated plate used to
bend the teeth; Figure 4 is a vertical section through same; and Figure 5 is a
view of a piece of card, in which are inserted a few of my improved teeth at
irregular intervals, in order to clearly illustrate the same.
In order to simplify the Drawings as much as possible, I have not shewn the
parts for pricking the holes, inserting the teeth, and for driving the teeth home in
the foundation, as the parts are the same, and operated upon in precisely the same
manner as is the case when setting ordinary card teeth.
The "gantry" of the machine is indicated by the letter A, upon which slides the
carriage B, which is traversod in the ordinary manner. In the journals B¹ a cam
shaft C is mounted, to which rotary motion is transmitted in the usual manner;
near to one end of this shaft is secured a cam D, which on revolving causos the
lever E to oscillate on the fulcrum F, raising and lowering the plate O at the end
of the same; the front edge of plate G is in contact with the foundation of the
card, and is for the purpose of supporting the crown of the card teeth, whilst the
second bend is given to the same.
To the cam shaft C is secured another cam D' which actuates the ordinary
crooked lever H, which is supported by the curved bracket H' fixed to the under-
side of the carriage B. This lever, operated upon by the cam D¹, actuates the
slide J and rocking bar K, to the latter of which is secured the perforated plate L.
When a tooth is inserted in the foundation, the perforated plate L is raised by the
cam D¹, until a portion of the perforation is above the top of the ordinary back
head bar M, thus allowing the points of the teeth to pass into the perforated space;
the plate L is then lowered, giving to the tooth the first bend at N, after which the
tooth is driven home by the ordinary mechanism; the cam D then raises the cross
bar or plate G such a distance that the upper edge of the same which is close to the

page_text: card foundation, supports the crown of the tooth until the second bend is given,
which is effected by the rising of the perforated plato L, the top edge pressing
against the underside of the tooth bends the same close to the foundation, as shown
in Figure 5 at P.
When under great pressure, the straight part of my improved card tooth at R
lays upon the foundation, which acts as a support, giving to the tooth more
strength, and when the straight part of the tooth does not rest upon the foundation,
the tooth is more elastic, and will operate upon the fabric with greater delicacy
than an ordinary card tooth, thereby producing a better and more elastic card, the
teeth of which will not so readily get out of shape when operating upon fabrics,
such as cloth, or plush, in order to raise the "nap."
What I claim as my Invention is,-
The perforated plate L, the additional cam D, and the bar G, seperately and in
combination, substantially for the purpose, and as described and illustrated by the
accompanying Drawings. The manufacture of cards, the teeth of which are formed
with two beads between the crown and the point.
In witness whereof, I, the said Joseph Sellers, have hereunto set my hand
and seal, this Twenty-second day of March, in the year of our Lord One
thousand eight hundred and eighty-two.
