Abstract

491,464. Screw sockets. VIROUX, A. D. A. J. April 24, 1937, No. 11823. Convention date, Sept. 19, 1936. [Class 89 (i)] Contamination of wood by a coach screw m inserted therein is prevented by winding a thin strip f of non - ferrous metal which is not liable to oxidize or rust in use into the female screw-receiving thread in the wood so as to lie against the bases of the male screwthread spirals and the flanks of the thread and so prevent direct contact between the screw and the wood. The strip may be inserted into the female threads by means of a mandrel.
