Abstract

1,036,710. Advancing mine roof supports. HOESCH-BERGBAUTECHNIK G.m.b.H. Feb. 4, 1965 [Feb. 4, 1964], No. 4939/65. Heading E1E. An advancing mine roof support comprises frame members which advance alternately with an advancing mechanism 1 between them disposed in interfitting outer and inner guides 1a, 1b for transmitting torsional forces which are removably connected in an articulated manner to the frame members by stub axles 5, 6. Each articulated connection is positively adjustable by an eccentic bolt 8 and a key 9. Between the guides 1a, 1b and the stub axles 5, 6 are bifurcated members 4a, 4b having slots 10a into which a key 9 can be inserted from either side of a stub axle 5, 6 to associate with a bolt 8.
