Abstract

898,591. Roof-supporting frames. HEMSCHEIDT, H., [trading as HEMSCHEIDT MASCHINENFABRIK, HERMANN]. Nov. 26, 1959, No. 40208/59. Class 20(2) In an arrangement for shifting an individual frame c of a row of roof supporting frames a, b, c, d, e, a chain l is secured to hook members on the vertical supports of the frame members b and d, and passes round a similar hook member m of a jack k which thus lies between the frame c to be moved and the chain. Operation of the jack causes the frame to be advanced into line with frames d, e, Fig. 2 (not shown).
