Improvements in Card Setting Machines.
I JOIN THORNTON of Carr Street Cleckheaton in the County of York
Machine Maker, do hereby declare the nature of this invention, to be as follows:-
The object of my invention is to attain a higher speed in card setting machines,
and to simplify and improve the different movements of the prioker, crown,
fingers, cutter, wire holder, feed motion and improvements in the method of
actuating the shell or nut barrel by the twill for endless or other sheets.
I operate the pricker by means of a rod with a finger or wing provided with
cap for holding the pricker blades, the shaft has a backwards, forwards and
Oscillating motion, the forward motion being for pricking, the oscillating motion is
for loworing or dropping the wing, out of the way of the finger and crown.
The crown and fingers are operated by two distinct and separate sectional bars
operated by tappets, this greatly reduces the weight of the respective parts.
The cutter movement is also operated by another separate bar placed under the
centre of the beforenamed bars and is actuated by a short stroke tappet so as not
to impede the fingers and crown.
The feed motion is obtained by a lever fulcrumed behind its feed tappet, thereby
reducing the stroke of the tappet and gaining speed.
1 employ fingers consisting of a plain forging (without boss and spring for
regulating the centre) with solid centres top and bottom attached thereto by
means of a screw and provided with two regulating screws at the top on each
side of the centre screw.
I employ a double V slide for actuating the shell or nut barrel by means of
the twill wheel thereby lessening friction and obtaining greater stability. The
horizontal wire holder is also operated by another horizontal bar thus making
a combination of five distinct sectional bars all operated by five separate and
independent tappets.

I JOHN THORNTON of Carr Street Cleckheaton in the County of York,
Machine Maker, do hereby declare the nature of this invention, and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
The object of my invention is to attain a higher speed in card setting machines,
and to simplify and improve the different movements of the pricker, crown, fingers,

page_text: cutter, wire holder, feed motion, and improvements in the method of mounting the
slide carrying the shell for forming the twill in endless or other sheets.

Fig. 10, is a plan of Fig. 9.
I operate the pricker A, by means of a rod B, with a finger or wing A', provided
with a cap B for holding the pricker blades A, the rod B has a backwards,
forwards, and oscillating motion imparted to it, the forwards. motion of the pricker
is for pricking, and is obtained by means of an arm or bracket C mounted upon a
rocking shaft or stud D this rocking shaft is actuated by lever E and bar F operated
from the cam shaft G by cam Gengaging with a projection or finger H on the
bor F, the aforesaid pricker rod and rocking shaft is returned preferably, by.
springs.
The oscillating movement is for moving the pricker clear and out of the way of
the crown and cutter bars as they come into action, and is effected simultaneously.
with the withdrawal of the pricker after pricking the holes for the tooth, this is
obtained by means of a cam J on the cam shaft G operating upon a projection or
finger J' on the pricker rod B. When the pricker is being fed to the card, for
pricking the required holes in same, it is raised into position by means of a
spring K attached to a second projection K' on the pricker rod B, this projection
works within an adjustable slide or guide L which ensures the pricker being in the
exact position required before it forms the holes for the uext tooth.
The crown M' and fingers U are operated by two separate and distinct sectional
bars M, N, operated by tappets M, N, engaging with projections or fingers H', the
crown M' and tongue M hold the wire N while it is being bent by the fingers U,
placed upon each side of the crown to form the tooth. When this has been
accomplished the respective cams feed the crown M' tougue M³ and fingers U, up
to the clothing A', the fingers guide the tooth into the holes and the tongue M
forces it into the cloth. When the tooth has been forced into the cloth, it is
operated upon by the crooker, at the back side of the card after which the crown
tongue M and fingers are withdrawn by the springs P' attached to the bars and
frame side.
The tongue M slides within or is carried by a suitable bracket N' attached to
the bars M, and N, before described. The crown M is mounted upon a pivotted
or crown bracket R', pivotted upon the bracket. N carrying the tongue. When
the crown releases the tooth, it is raised by the ordinary lifting bars and with-
drawn, clear of the pricker A which immediately comes forward to make the holes
for the next tooth.
The cutter S¹ I preferably operate by means of a separate bar P, placed between
the centres of the beforenamed bars M, N, and alongside the tongue, or between
the lefthand finger and the tongue, which holds the wire when making a tooth, the
said cutter is actuated by a short stroke tappet or cam P', on the tappet or cam
shaft, and in such a manner that immediately the tongue and crown grip the wire

page_text: for the next tooth the cutter S coines forward and cuts it off, it then returns to its
original position by the spring P, independently of and so as not to impede the
action of the fingers and crown.
I employ fingers U shown in Figs. 3 and 4, consisting of a plain forging R
(without boss and spring for regulating the centre) but with solid centres R', top
and bottom, attached thereto by means of a joint screw S and provided with two
regulating screws T at the top on each side of the centre screw; the centres.
I preferably form with convex bearing surfaces, so that the finger U may be
adjusted, (that is raised or lowered) to the position of the wire, in a firm and
efficient manner, without liability to injure the attachment screw S; or for single
and
end finger (see Figs. 7 and 8) I employ a solid centre with a knuckle joint V,
the adjusting mechanism T applied to the end of the finger, this knuckle joint acts
as an additional support to the attaching screw S and takes the strain off same-
during adjustment.
The fingers U are mounted upon a suitable fixed centre stud U¹ attached or
resting upon centres in the ordinary pillar bracket U'.
Tho feed motion in this machine is obtained preferably by a lever W, fulcrumed
behind its feed tappet W thereby reducing the stroke of the tappet and gaining
speed, the grip X in connection with the aforesaid feed is pivotted upon the
slide Y by a stud Y at an angle from the nipping point Y', upon the other end of
this grip X, is a second stud Y, working within a alot Z upon the feed lever, by-
this means, instantaneous grip is obtained the moment the feed tappet takes hold
of the feed lever, the said grip being liberated by tappet Z' on delivery, and
returned to its original position by a spring Z³.
The wire is fed from a reel or block by means of the feed lever W, then the-
wire is again seized by a second gripper W, operated by cam W upon the cam.
shaft, and beld until the feed W is returned and has again taken hold of the wire
for a second feed, when the gripper releases the wire which passes through a cutter
die W, and is seized by the tongue and crown, the cutter then cuts off the required
length, which is immediately bent by the fingers, so forming the tooth, the crown
and fingers are then fed up to the cloth, the tooth is forced into same, and then.
operated upon and bent by the crooker, when the tooth is finished, this operation is
repeated.
In mounting the shell for forming the twill upon endless or other sheets see
Fig. 6, 1 employ a double V slide Z³, fixed upon the bed, in this slide work the
wings V of the shell V, by this means the friction of the carriage or slide upon
the bed is greatly reduced.
The shell V carries the ordinary card setting mechanism, and when forming the
twill it is given the ordinary lateral to and fro traverse by means of the screw-
shaft V, operated by the ordinary twill motion.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what 1
claim is :-
1. In card setting machines the use and employment of a pricker having a.
forwards, backwards, and oscillating motion imparted to it by means of fingor C
upon rocking shaft D projection or finger J' on pricker rod B operated by cams.
and bar from the cam shaft, projection K', guide L and spring K, in the manner
and for the purposes substantially as shown and described."

independent of the bed for the purposes substantially as described.
