PITCHER
SAMPLER
Now built under license from Pitcher Drilling Company, Inc. by Acker Drill Co., Inc.
recovers accurate samples
from soft rock, friable shales
and problem clays.
The Pitcher Sampler is designed specifically to recover accurate samples from formations
that are too hard for thin-wall shelby samplers or too brittle, soft or water-sensitive to
permit satisfactory recovery by conventional core barrel type samplers. Several years of
successful application in virtually every type of "problem" formation prove that PITCHER
SAMPLER saves time, saves money...insures exceptional accuracy. If you're now using a
core barrel type sampling tool, compare it with these exclusive features offered by the
PITCHER SAMPLER...
Heavy-duty, triple ball-bearing hang-
er is sealed 4-ways against drilling
fluid to prevent freeze-ups and in-
sure long, trouble free service.
No more crumpled shelby tube; no
presetting, no surface control need-
ed. Spring-seated tube telescopes
into cutter barrel as formation hard-
ness increased.
Sliding valve directs drilling fluid
through shelby tube to hole bottom
for thorough flushing action, then
automatically diverts fluid from tube
when tube contacts bottom.
Hole remains full gage...no reaming
needed.
Drilling fluid can't undercut shelby
tube and erode or contaminate sam-
ple even in softest materials.
Samples dry or saturated material
with equal speed, ease and accuracy.
No core lifter is needed to protect or
retain sample.
Sample all materials- including soft
rock -from top to bottom of hole.
Shelby tubes can be changed in less
than 45 seconds.
Drill can be stopped, rod re-chucked
(even raised slightly) without break-
ing core.
...a tool that relieves you from the limitations
of core barrel type samplers
