Abstract

634,825. Wall plugs. BILSTEIN, A. Oct. 31, 1947, No. 29175. Convention date, April 17. [Class 89 (i)] Wall plugs comprising a sleeve 2 split to form wings 3 with perforations having rough projections 5, have one projection of each group longer than the others and provided with a hooked end 7 to enable a firmer grip to be taken on the wall of the hole when the sleeve is expanded by the wedge end of the bolt. The perforation may be formed by drifting in an oblique direction, or the sleeve may be cast. The sleeve may be in sections.
