Abstract

648,267. Washers. ILLINOIS TOOL WORKS. July 29,1947, No. 20402. Convention date, Feb. 16, 1942. Drawings to Specification, [Class 89 (i)] [Also in Group XXII] A strip of washers comprises a number of longitudinal rows; the washers of each row are joined to adjacent washers of the row and of the adjacent rows by narrow connections permitting easy severance. The strips may comprise a single row only and may be supplied in coiled form. In the case of externally toothed lock-washers the connection is by the tips of some of the teeth the twisting of which has already effected a part severance.
