This invention. relates to holding devices for
wires or cords which must be held taut during
jecting portions of pins l6 and I’! and plate 23
spaced outwardly of the base member. An addi
tional wire holding pin 29 projects longitudinally
from base I5 and has a sharp edge 29a.
In operation, at the start and during the prog
such manipulation of the wire or cord as the
winding of coils.
Coil winding machines, particularly for small
motor armatures, are provided with hooks or pins
conveniently located to receive a coiled end of
the wire being wound and hold the wire taut
during manipulation. However, at the end of the
Winding, it is necessary for the operator to un
wind or pull the wire from the pin or hook and
this is difficult where very fine Wire is used.
The object of the present invention is to pro
vide such a holding element for the end of a
wire or cord being manipulated together with
means for quickly and conveniently sweeping or
casting off the wire from the pin at the end of
the winding operation.
This object and other more detailed objects
ress of the winding, wires 26, 21, and 28 are
intermediately looped about pins l6 and I1, thence
passed between guides 30 of the winding machine.
The extreme end of wire 28 is coiled about pin
29 and edge 29a used to break off excess wire.
After the coil is completely wound, the operator
strikes actuating plate 23 to move it and push-off
plate 22 to the position shown in Fig. 4 which
sweeps the wire loops from pins 16 and I1 and
also pulls the end of the wire from pin 29. This
leaves the ends of the various coils free for at
tachment as by soldering to the commutator bars.
Since actuator plate 23 is relatively large and
the wires may be released from their holding pins

simply by striking the push-O?’ member, this oper

Obviously, the number of holding pins may be
