Abstract

1517576 Percussive tool IMPEX-ESSEN VERTRIEB VON WERKZEUGEN GmbH 19 Aug 1975 [7 Sept 1974] 34358/75 Heading B4C A machine for producing grooves in concrete comprises means for producing hammering and reciprocatory motion of the bit. As shown in Fig. 1 a hammer piston 16 is driven via an air cushion 17 from a piston 19 driven from an electric motor; the same motor produces, through bevel gearing 13, 14 and an eccentric drive 12 oscillation of the drill bit. The drill bit is formed as in Fig. 2 and is scoop shaped to assist clearing of debris. It has a captive nut 25 and teeth 24 which engage similar teeth on the drill spindle. In a modification reciprocating motion is produced by a varied piston each vane being located in an annular sector and being positively driven by pressure air in alternate directions.
