This invention. relates to automatic stop-re
corders, and relates more particularly to stop re
corders employed in connection with a warp
knitting machine.
During the production of knitted fabrics, par
ticularly warp-knitted fabrics, a defect known as
a “stop-mark“ results each time the knitting ma
chine is stopped. The number of such stop-marks
in each bolt of fabric produced by the knitting
machine is partly determinative of the grade of
the knit fabric; the greater the number of stop
marks, the lower they grade of the knit fabric.
Normally a record of the number of such stop
marks. is kept by the machine operator on a qual
ity cardy which accompanies each bolt. of fabric,
but this record cannot be relied upon to grade
the fabric owing to the uncertainty as to its com
pleteness. Accordingly, it has been necessary to
inspect visually each bolt of fabric to determine
the number of stop-marks, present in the knit
fabric and assign a grade thereto based on the
results of this inspection. Gbviously, the labor

Referring now to the drawings for a detailed

The ratchet wheel 62 is operated by means of a

thereof for engagement with ratchet teeth 68.
The other end of the spring pawl 66 is fastened
as by means of rivets 69 to an arm 16 extending

numeral 14 is mounted for sliding movement on 1‘
the free end of the shaft 59 by means of a taper
pin 16 extending into a keyway 11 in the shaft.
The carriage includes two tapered sections 18
having therebetween a straight section 1s denn
ing a generally U-shaped peripheral channel 8|.
At one end of the carriage is a lug 82 carrying a
cylindrical block 83 having a pin 84 at its end.
The carriage is operated, as will be described with
more particularity below, by means of a bar 86
riage 14 along the shaft 59 thereby driving the
il.
one end of which ñts into the channel 8| and the `
other end of which has a notch 81 to engage the
shaft 41 carried by the plunger 46. The bar 86
is pivotally mounted by means of a stub shaft
88 between brackets 89 and 9| carried by the arm
54, the bar being ñXed to and rotatable with said
stub shaft. A collar 92 is fastened to one end
Voi' said stub shaft 88 and carries a ratchet oper
ating rod 93 which bears against the under sur
face of the spring pawl 66.
In Figure 4, there is shown a circuit of the elec
trical connections between the stop-recorder of
our invention and the warp-knitting machine
with which it is employed. The circuit includes
a warp-knitting machine indicated diagrammati-
cally at |0| which receives three-phase power
from lines |02, |03 and |64 through a manually
operated switch |06 and a motor starter indicated
generally by reference numeral |81. The motor
starter includes three terminals |88, |09 and |||
to which the power lines are fastened and switches
II2, |13 and ||4 which may be closed by the op
eration of actuating bar ||6 to start the warp
knitting machine |0 |. The starting circuit which
operates the actuating bar | I6 extends from the
power terminal ||| through a normally open
push-button switch l l1 to a normally closed sole
noid operated switch indicated generally by ref
erence numeral || 8. From the switch | I 8, the
starting circuit is completed through a solenoid
pin 84 through the card 24 into the groove I9.
So long as the switches | I3 and | | 4 remain closed
and the knitting machine continues to run, it
will be impossible to remove the card 24 from ‘the
stop-recorder since it will remain engaged by the
pin 84. The rotation of the bar 86 will also ro
tate the rod 93 upwardly against the spring pawl
66 ñexing said spring pawl and the leaf springs
13 and moving the hook 61 past one of the teeth
68.
The warp-knitting machine |D| may be stopped
by opening a normally closed push-button switch
13| in the starting circuit, or by means of a stop
motion |32 which may be of the type shown in
United States Patents Numbers 2,290,257 and
2,403,548 or in our application Serial Number
r191,538 filed December 13, 1947, or of any other
type. The stop-motion |32 is connected in paral
lel with the switch contacts |2| and will com
plete the circuit from the power terminals |22
and |23 through the solenoid coil |24 in the event
that a warp thread breaks or snarls or the fabric
being produced is imperfect. This will move the
switch |26 away from the contacts |21 to open the
starting circuit and thereby stop the warp-knit
ting machine.
When the switches ||3 and || 4 are opened to
stop the warp-knitting machine, the flow of cur
rent through the coil 44 of the solenoid 39 will
be interrupted. This will permit the leaf springs
13 and the spring pawl 66 to force the rod 93
downwardly, rotating the bar ‘86 in a clockwise
direction and thereby carrying the pin 84 clear
of the card 24. The downward motion of the
spring pawl 66 will also index the ratchet wheel
, 62, which will in turn index the shaft 58 and the
carriage or punch 14 to align the pin 84 with
' another area on the card 24.
The stroke of the
2,495,825

vspring pawl 66 is preferably adjusted so as to be
somewhat longer than the height of one of the
ratchet teethy 68 to insure that the downward
motion of the springk pawl will move the pin S4
clear of the card before the spring pawl engages Gl
