receptacles, Serial No. 72,589, filed April 3, 1936,
and on the invention shown, described and

The source of supply for the plastic material
is exemplified as a usual stuffing machine 4I, in
pans II in which to bake meat loaves. vPlastic
material which is to be placed in the receptacles
is represented as meat dough, exemplified at I2.
The material is arranged to be fed into the recep

comprises a feeding channel I4, shown as a tube,
provided with a feeding passage I5 and a feeding
head I6, which is instanced as serving as a pres
10 sure piece, having a feeding passage Il, which
which the supply of'rmeat dough is contained.
The meat'dough is arranged to be forced through
a suitable valve 42, connecting with the interior
of the stuffing machine. 'I‘his forcing of the meat

`
In order to provide a supply of fresh pans under
the plunger upon successive descents of the "
‘plunger and to insure non-interference `between
the plunger and said pans, »I provide a feeding
means for the pans controlled by the position of
the plunger' to avoid interference between move

by a positioning nut 9|, a jam nut 92 clamping
