Abstract

1,061,071. Advancing mine-roof supports. GULLICK Ltd. Feb. 4, 1965 [March 20, 1964], No. 11979/64. Heading E1E. In an advancing mine-roof support comprising at least one rear prop 11 and at least one forward prop 12 articulatedly mounted on a common base 10, the forward prop or props are tilted as shown. Each prop assembly 11, 12 is provided with a cantilever extension 21 which is individually and manually set by a wedge 22 or jointly set by a jack 23, 24 and link mechanism 25. A telescopic shield 28, 29, 31 is carried by the rear part of the support being secured to the base 10 and articulated to the roof-bar structure by a pin and slot connection 30. A jack 32 is provided to compensate for roof convergence when the support is set.
