Abstract

1,019,048. Advancing mine roof supports. A. HAARMANN. Jan. 23, 1964 [Jan. 25, 1963], No. 2894/64. Heading E1E. In an advancing mine roof support particularly for inclined seams a floor plate 2 carrying four props 3 is guided against tilting or slipping down the incline during advance by the arms 11, 12 of a spring steel stirrup 9 pivoted to a conveyer or rail 8, the arms 11, 12 passing through holes in guide plates 15, 16 on the plate 2. The support is advanced by a ram 7 connected to the conveyer 8. The yoke 10 of the stirrup engages eyes 13, 14 on the conveyer, the lower eye 13 being slotted to allow angular displacement between the conveyer and yoke. A fifth prop 6 is connected by rods 4 to the plate 2. The height of the plates 15, 16 may be relatively adjusted to allow for the inclination between the plate 2 and conveyer 8. Alternatively the arms 11, 12 may be twisted relatively to each other.
