Abstract

1,209,611. Eauth-graders. J. CURLETT and R. A. GURRIES. 16 Oct., 1967, No. 47110/ 67. Heading E1F. A grader, e.g. a motor grader or bowl scraper, is able to make, when moving over ungraded ground, a grade in conformity with a reference grade because the front end of the grader member-supporting structure 10 of the grader is supported on a pair of transversely spaced wheels or sets of wheels 16, 16' so that the front end of the structure may 'be adjusted vertically of the wheels or wheel sets in response to changes in the relationship of sensor means 82 with the reference grade W. A preferred embodiment discloses a motor grader in which the beam is supported through jacks 54, 54' on the swing link systems 42, 42' interconnecting the wheels or wheel sets 16, 16'. The expansion and contraction of the jacks 54, 54' is controlled by the sensor 82 operating a servo system controlling the valve means of the fluid supply system of the jacks so as to maintain the sensor in a predetermined relationship with the reference grade W. A pendulum-controlled circuit is also provided for appropriately adjusting the tilt of the grader blade 30 transversely of the frame to compensate for variations in the transverse tilt of the frame as the grader advances.
