Abstract

1,226,632. Earth grader actuator, extensionindicating device. L. W. HUTT. 20 March, 1969 [21 March, 1968], No. 35438/70. Divided out of 1,226,631. Heading E1F. An indicator for showing the degree of extension of a piston-cylinder actuator of a grader comprises two telescopically associated members 36, 38 respectively coupled through ball joints 39, 37 to the anchorage points 35, 34 of the piston and the cylinder of the actuator and an indicator 40 on the outer of the members 36, 38. The indicator co-operates with a scale 41 on the cylinder or on a plate fixed to the cylinder. The grader forms the subject matter of the referred to Specification 1,226,631.
