Abstract

1,037,920. Advancing mine-roof supports. K. M. GROETSCHEL. Jan. 29, 1963 [Jan. 29, 1962], No. 24502/65. Heading E1E. In an advancing mine roof support assembly comprising a rear unit and a forward prop unit interconnected by leaf springs and advancing jack means, the roof supporting frame is provided with a non land-bearing shield. A leaf spring is fixed to a bracket on the forward prop unit and slidably extends through a guide lug on the rear unit for alignment purposes. For modified arrangements of roof superstructure the Specification Drawings (not shown) should be referred to.
