Abstract

1,082,766. Connections between mine-roof support frames. HERMANN HEMSCHEIDT MASCHINENFABRIK. Aug. 25, 1965 [Sept. 22, 1964], No. 36509/65. Heading E1E. The props 4 of two relatively advancing mine roof support frames are interconnected by upper and lower flexible links 1 each of which has a pin 2 welded thereto and is slidably mounted in a slotted fitting 3 secured to the prop 4. The pin 2 is held in position by a square-section key 8 and adjusting means in the form of a key or screw means is provided for angular alignment purposes, see also Figs. 2, 3 and 4 (not shown).
