Abstract
1,069,904. Advancing mine-roof supports. K. M. GROETSCHEL. May 14, 1964 [Aug. 29, 1963], No. 20051/64. Addition to 1,037,918. Heading E1E. In an advancing mine roof support as disclosed in the parent Specification, the roof superstructure is provided with pivoted cantilever extensions 8, Fig. 2, which are actuated by wedges 9 operated by hydraulic rams 9a. The angle of advance of the support may be controlled by a steering ram 25, Fig. 4, which operates a slider 22 through a pin-and-slot mechanism 24, the slider acting in turn on a guide bar 28 connected to the traction ram 29.
