Abstract

564,137. Drilling. ETHERINGTON, E. J., and WEYMANN'S MOTOR BODIES (1925), Ltd. March 10, 1943, No. 3925. [Class 83 (iii)] Relates to the jigdrilling of holes with a portable hand-held drilling machine and consists in mounting a block on the drill housing to ensure that the holes drilled are normal to the jig surface. The block is preferably of channel section 14, the edges 15 of the flanges contacting with the surface 21 of the jig. A bush 17 is screwed into the web of the channel and the sleeve 11 of the drilling machine 10 is secured in the bush by a screw 19. The drill 12 is supported and guided by the usual conicalended spring-pressed bush 13 sliding in the sleeve 11. The conical end locates in taper holes in the jig and as drilling proceeds the bush is forced into the sleeve 11 against the spring pressure. Specifications 191,230 [Class 83 (iii)], and 356,942 are referred to.
