Abstract

1,205,586. Excavators. ERNEST A. WEBB Ltd. 11 Nov., 1968 [28 Nov., 1967], No. 52110/ 68. Divided out of 1,205,585. Heading E1F. Hydraulic circuits between power supply points on the tractor-mountable stand of a shovelling assembly and the stand-supported turret 11 of the assembly are maintained as the turret is rotated by rack and pinion means 14, 15 about a shaft 16 through 180‹ to either side of a mean position by flexible pipes 18 arranged within the stand and connected by swivel sections 19 to either the supply points on the stand or to the supply points on the turret. Specification 1,205,585 is referred to.
