Abstract

918,426. Forming cavities in concrete. FELDMANN, A. Aug. 22, 1980 [May 23,1959; June 18, 1959], Nos. 17657/59 and 21019/59. Class 20 (2). [Also in Group V] A former 1, Fig. 5, for forming dovetailshaped cavities in concrete &c. is of rubber &c. and has a cavity in which is a core 2 having a bolt 3 to secure the former to shuttering 5. The core is removed with the shuttering and the rubber part 1 removed subsequently. In Fig. 6 the core 2 is cylindrical and the bolt 3 is screwed into a dovetail-section member 6 which engages a cavity in the base of the former 1 and secures the former to the shuttering 5. The core is removed with the shuttering by a disc 8 on the bolt 3 after it has been unscrewed from the member 6 and the former is removed by the bolts 91 in nuts 9 in the former and the member 6 is finally removed. In a further modification, Fig. 7 (not shown), the former and the core are secured to the shuttering by separate bolts and the bolts securing the former are removed in order to remove the shuttering with the core.
