Abstract

800,502. Wall - plugs. WORNDLI, W. March 14, 1957 [May 7, 1956], No. 8410/57. Class 89(1) An expanding wall and like plug comprises a sleeve 1 having an internal screwthread 3 and slit at 2 from the end 4, the sleeve bore tapering towards said end, and a spreading member 5 and an insert 6 in the bore. When a screw 7 is applied to the plug, insert 6, e.g. of lead, is deformed and member 5 is moved to spread the slit end outwards. The deformed insert holds member 5, which may be conical or spherical, so that the screw can be removed and replaced. In a modification for use with a wood-screw, the insert consists of a tubular member receiving the screw in its bore.
