Bishop discloses a mobile backfilling machine wherein raw
materials located adjacent an excavated trench are picked up,
graded and delivered to the open trench in an order of size

material padding for a product which has been placed into the
trench. Bishop teaches that the machine is intended for

materials from trench 44 and which typically lies parallel to
and adjacent such excavated trench 44 (see Figure 3), on
ground grade 12.
