Abstract

358,360. Combination tools. PEACE, F., 76, Matlock Road, Walkley, and SORBY & SONS, Ltd., R., 139, Norfolk Street, both in Sheffield. Dec. 6, 1930, No. 36863. [Class 61 (iii).] Screwdrivers.-A screwdriver is provided with a bradawl, gimlet, &c., which may be brought into position to form a hole. A bradawl a is pivoted at b to the screwdriver c and may be retained in the operative position, shown in dotted lines, or in the inoperative, shown in full lines, by a ring e. The blade may be grooved to prevent movement of the bradawl. In modifications the bradawl may be hinged so that it swings outwardly from the blade, or may slide on the blade and carry studs to engage upper or lower branches respectively of bayonet slots in the blade in the two positions. In all forms, the auxiliary tool is carried in both positions entirely along the outer surface of the screwdriver.
