Abstract
956,797. Yielding mine arch supports. M. VON LINSINGEN, [trading as BOCHUMER EISENHUTTE HEINTZMANN & CO.]. Dec. 22, 1960 [Dec. 30, 1959], No. 44020/60. Heading E1E. In a mine arch support a clamp for clamping together two channel shaped members having flanges 3, 4 comprises two parts held by screws 11, one part having shoulders 14 which bear against the flanges 4 and which have ribs 15 on their surface whereby when the channelshaped members are under compression the ribs exert a force on the channel-shaped members directed inwardly thereof.
