causes the stop projection 124 on the lever 125 to ride on
the periphery of the pawl ring 119. When the lock shoul
der 123 on the pawl ring 119 engages the stop projection
124, the rotation of the pawl ring 119 is stopped and,
‘likewise, rotation of the shaft 94 is stopped. Thus, the
rod 131 only momentarily pivots the lever 125, even.
though the ?nger 135 should remain depressed, and this
assures that the marking apparatus will operate only
through one cycle of operation each time that the con
trol ?nger 135 is depressed.
_
In the operation of the marking apparatus, when the‘
marking apparatus is in idle position, the various parts
are in the positions illustrated in FIGS. 5 to 9, and a
severed label strip 10 is suspended in the guides 73 and
74 across the heat sealing platens 49, the severed label
strip being held in elevated position in the guides 73 and
In FIGS. 18 and \19 there is shown another way of
assuring proper feeding of'the projected label strip into
the suspended guides adjacent the heat sealing platens 49.
Here, the upper guide 74 is secured by a bracket 155 to the
heat sealing platen carrying arm 48 and a guide 156,
which telescopes over the lower guide 73, is secured by a
bracket 157 to the heat sealing platen carrying arm 47.
Since the feeding of the end label strip into the guides
occurs when the heat sealing platens 49 are closed, the
guides 74 and 156 are brought together during the feed
ing operation so that projection of the label strip into
the upper guide '74 is completely assured. After the
feeding of the label strip has been completed, the guides
74 and 156 are separated when the heat sealing platens
are separated and the label strip is then suspended across
the heat sealing platens 49 for the next cycle of operation.

is suspended in the guides 73 and 74. As the limb 18
is advanced, as shown in FIG. 11, the narrow interme

upon reference to this disclosure and, therefore, this inven

operation is initiated. The high well of the cam 59 allows
closing of the heat sealing platens 49 so as to heat seal
together the wide end portions 14 of the label strip 10, as
illustrated in FiG. 12. As soon as the heat sealing
platens 49 start to close, the cutter means 96, 98 open
to allow passage of the Web 11 therethrough. At this
time, also the feeding roll as is rotated and the cam
86 on the shaft of} allows the pressure roller 82 to engage
the web 11 to initiate advance of the web 11, so as to
having a heat sealable thermoplastic coating on one side
thereof adjacent and across the normally open heat seal

facing away from the platens so that, when a limb of
the fowl is passed between the normally open platens, it
engages the intermediate portion of the releasably end
suspended label strip to draw the label strip between the
normally open platens, to cause the intermediate portion
of the label strip to encircle the limb and to cause the
project the end label strip thereof into the guides 73 and
thermoplastic coated end portions of the label strip to

ing of the web is initiated by the coaction of the pressure
of the limb of the fowl from between the normally open
roller 82 and the feeding roll 69, the continued feeding of
the web is accomplished by the coaction of the pressure 65 heated heat sealing platens for moving the platens to
closed position to heat and press together the face abut
