Abstract

399,142. Mine-supports. K R U P P AKT.-GES. FRIEDRICH-ALFRED-HœTTE, F., Rheinhausen, Neiderrhein, Germany. Dec. 21, 1931, No. 35338. Void [Abridged as open to inspection under Sect. 91 of the Acts, Jan. 14, 1932]. [Class 20 (ii).] Relates to supporting-frames for tunnels and the like of the kind comprising two substantially vertical posts which support a horizontal transverse girder. According to the invention, a pin 5, Figs. 1 and 2, is secured to each post 2 and is arranged to project through a hole 11 in the girder 10. In the form shown, the post 2 is of I section and the pin 5 is slotted at 4 to fit over the web 3 to which it is welded. The upper end 8 of the pin is of reduced diameter and terminates in a shoulder 9 which projects slightly above the upper end of the post 2 and thereby forms the support for the girder.
