three way valve 118 controls the flow of hydraulic fluid to cylinders 30 and 36 to control
the raising and lowering of main frame 16 and the tilting of vibratory frame 18 to a
vertical position relative to main frame 16. The driver of tractor 14 controls the
movements of main frame 16 and vibratory frame 18 from suitable controls shown at
120 in Figures 4 and 5. Three way valve 122 controls the raising and lowering of push
tube 68. Valve 124 controls the operation of motor 94 for vibrator 90. Valves 122 and
124 are manually controlled by the operator of implanting device 12 seated on seat 108
from suitable controls shown at 126 in Figures 4 and 5.
In operation, with support frame 16 in a raised position and the lower end of
push tube 68 raised from the ground or earth E about eighteen (18) inches, the
operator of implanting device 12 seated on seat 108 grips a geophone 100 to be
implanted with a hand held tool (not shown) below lugs 102 and places the
geophone within slot 96 of tube 68. Next, the driver of tractor 14 lowers main frame 16
by actuation of cylinders 30 until prong 106 is near the ground or earth surface E.
Berquist teaches (column 4, lines 62-67) that "[i]t is normally desirable to implant
geophone 98 in a vertical direction in earth E. Consequently, cylinder 36 is actuated by
the driver of tractor 14 to position vibratory frame 18 along with the intermediate frame
and push tube 68 in a vertical relation." Then, the operator for implanting device 12
actuates cylinders 56 to lower push tube 68 with the geophone 98 retained within slot
