Abstract
1,147,643. Advancing mine roof supports. W. E. & F. DOBSON Ltd. 3 June, 1966 [11 June, 1965], No. 24694/65. Heading E1E. The rear prop unit of an advancing mine roof support is provided with an articulated base extension 5 which extends towards the goaf side and pivotally supports an arcuate shield 9, 11 having guided sliding engagement with a roof plate 4 of box-section. The front and rear prop units are interconnected at the base by U-shaped plates, the arms of which pass through slotted brackets incorporating rubber buffers 18, see also Figs. 8, 9 and 10 (not shown), for a modified arrangement.
