Abstract

618,489. Making wall plugs. WALL'S, Ltd., and BAYLISS, J. Nov. 8, 1946, No. 33197. [Classes 83 (ii) and 83 (iii)] [Also in Group XXV] Wall plugs are formed from resilient sheet metal blanks 11, Fig. 1, formed with central notches 20 and with half notches at each side. The ends are slit and cut at 15, 16 so that on the blank being curled to cylindrical form the ends form out-turned parts, Fig. 3. Drills for use in chambering holes to receive. plugs made as above have the ends tapered at 24, slotted at 26 and provided with a central hole to receive the stem 29 of a conical headed plug 28. The ends of the bits are provided with cutting edges so that on rotation under axial pressure they cut away the wall at the end of a hole, the coned parts of the heads 28 effecting expansion. The bit has an axial bore 25 extending the whole length of the bit to permit introduction of a drift to knock out the plug 28 for removal of the bit from the chambered hole.
