Abstract

187,147. Williams, M. Oct. 31, 1921. No Patent granted (Sealing fee not paid). Letters, numerals, and the like.-Letters &c. are provided with projections of non-circular crosssection. The smaller axis c, d of the projection is less than the width of the groove in to which it is to be inserted. This allows the letter to be inserted sideways; it is then turned into the upright position, and the longer axis e, f of the projection engages tightly with the sides of the grooves. In a modification the end of the projection may be larger than the shaft, a T-shaped groove being provided.
