Abstract

556,145. Screws; spanners. DIXON, F W. Feb. 19, 1942, Nos. 2227 and 14351. [Class 89 (i)] [Also in Group XXIII] Grub screws have means for rotating them machined by means of rotating tools. A hole 1 may be drilled in the screw 2 and continued by a smaller eccentric hole 3, or one, two or more small holes 7 may be drilled off centre. In a further modification a hole of irregular curvature 10 may be produced by a drill that is allowed to wander. The tools for rotating the screws are correspondingly formed, that for the screw, Fig. 2, being a rod to enter the hole 1 with an eccentric projection is fit, preferably loosely, the hole 3. A contoured rod to fit the hole 10 may be produced by drawing through a die correspondingly drilled. The projections may be on the screws and the recesses in the spanners.
