Abstract
398,029. Mine-roof supports. TOUSSAINT, H., 23, Waldmannstrasse, Lankwitz, Berlin, and BOCHUMER EISENHœTTE HEINTZMANN & CO., GES., 33, Blucherstrasse, Bochum, both in Germany. Sept. 17, 1932, No. 25924. Convention date, Sept. 19, 1931. [Class 20 (ii).] Mine-arch supports are formed curved of channelsection irons with terminal flanges 1. The flanges may be of the same thickness as the webs 3 and cross-connector 2, or for greater lateral strength the flanges and cross-connector may be thicker than the webs, as shown in Fig. 2. The arch may be made in one length, or in two lengths 15, 16, with an overlapping joint, as shown in Fig. 4. The Specification as open to inspection under Sect. 91 comprises also the use of this sectioniron for props, prop caps, and tunnel lining, and also describes a roller joint 10 for overlapping sections of irons, 8, 9, Fig. 5 (Cancelled). This subject-matter does not appear in the Specification as accepted.
