The left-hand end of the motor 210 has a circular plate
‘218 secured to it, and that circular plate is also secured 35 As those clamping frames move upwardly, they will move
the anti-friction bearings 46 and their counterparts up
to a ?ange 216 at the left-hand end of a semi-cylindrical
support 214. The right-hand end of that semi-cylindrical
support is suitably secured to the plate 206, as by welding.
The plate 218 has an opening therein, and the shaft 220
of the hydraulic motor extends freely through that open
ing. That shaft extends into a bracket 222, and it is
suitably ?xed against rotation relative to that bracket
by a pin or the like. The bracket 222 is formed at the
upper end of a support which extends downwardly and
laterally to the framework which underlies the ears 125
and 126. As a result, the shaft 220 of the motor 210
is ?xedly held against rotation.
The numeral 224 denotes a hydraulic line which ex
tends between one of the ports of the hydraulic motor
210 and one of the ports of a four-way, spring-centered,
double-solenoid valve 228; and a hydraulic line 226 ex
tends between the other port of that hydraulic motor and
another port of that valve. A hydraulic line 230 extends
between one of the outlet ports of a hydraulic pump 234
and another of the ports of the valve 228; and a hydraulic
line 232 extends between the remaining port of the valve
228 and a tank 236.

92 and 192 and thereby raise those sleeve-like portions up
40
out of engagement with the concave, cradle-like braking
surface 28 and its counterpart. As those anti-friction
bearings raise those sleeve-like portions, the motor hous
ing 210 will be able to rotate relative to the ?xedly-held
shaft 220, and will thus be able to rotate the container
168 relative to the supporting framework 82 and its
counterpart. As the container 168 approaches the de
sired dumping position, a “stop” push button can be
pressed; and that push button will cause the valve 228
to halt further ?ow of hydraulic ?uid to the motor 210
and will cause the valve 248 to apply hydraulic ?uid to
the cylinders 90 and 190 and cause retraction of the
plungers of those cylinders. That push button will also,
after a few seconds, cause the motor which drives the
rotor of the pump 234 to become de-energized. As the
plungers of the cylinders 90 and 190 move toward their
retracted positions, they will cause the links 69, 70, 169
and 170 to rotate back to their normal positions; and as
those links so rotate they will rotate the double-threaded

A hydraulic line 252 extends from another outlet port
by the concave, cradle-like braking surface 28 and its
counterpart and by the clamping portion 34 and its
of the pump 234 to a third port of the valve 248, and a
hydraulic line 250 extends between the remaining port
counterpart. The short duration, continued energization
of that valve and the tank 236. A hydraulic line 256
extends from the remaining outlet port of the pump 234
to the tank 236, and a suction line 254 extends from the
tank 236 to the inlet port of the pump 234.
In the normal condition of the vibrating device pro
of the motor which drives the pump 234 will enable that
pump to provide the hydraulic ?uid needed to re-clamp
the container 168.
When the container 168 is to be returned to its upright
position, a “return” push button can be pressed; and that
vided by the present invention, the plungers of the 75 push button will re-energize the motor which drives the
3,071,901
rotor of pump 234 and will again energize the valves 228
and 248. The valve 228 will be actuated in such a way
that the hydraulic fluid which is supplied to the motor
210 will tend to rotate the motor housing 210, and hence
the container 168, toward upright position. The valve
248 will cause hydraulic ?uid to pass into the cylinders
that container for rotation, that handle or lever would
be used to rotate the links 7169 and 170 to the dotted-line
positions in FIG. _3 and would be used to rotate the links
69 and 70 to corresponding positions.
j
Also, if desired, the container 168 could be rotated
90 and ‘190 and move the plungers of ‘those cylinders to
extended position; ‘and thereupon the links 70 and 170
will rotate-the link 170 rotating in the counter clock
wise direction in ‘FIG. 3. As those links rotate, they
will act through the adjustable tie rods to cause the links
69 and 169 to rotate—the link 169 also rotating in the

the position shown by FIG. 3 ‘and .would be used to rotate
the links 69‘ and 70 to corresponding positions. To free
manually, rather than by the use of hydraulic power.
10 Where that is to be done, the motor 210 would be re
moved and a segment similar to the segment shown in
the said application would be mounted on one of the
counter clockwise direction in FIG. 3. The rotation of
the ‘links 69, 70, 169 and‘170 will cause rotation of the
ends of the container 168 and a pinion would .be disposed
in engagement with that segment to rotate that container.
