Abstract

514,085. Darts. SHILSTON, L. E., and SHILSTON, H. E. Feb. 18, 1939, No. 18730. Divided out of 514,079. [Class 132 (iii) ] In a dart flight composed of a pair of light rigid laminar half-flights, Figs. 1 and 2, slit to interfit crosswise as described in Specification 496.381, one or each half-flight is provided with one or more pairs of projections x, y located on each side of a line in continuation of the slit and so spaced as to provide a sliding fit for the complementary half-flights. The halfflights are stamped from sheets of aluminium or other light material and, to enable a single set of dies to be used, the two. half-flights of each pair may be identical and symmetrical about an axis passing at right angles to, and through the inner end of the slit. The trailing edge of the flight may be indented or pointed, and the projections x, y may be elongated or stud-shaped. Specification 514,079 also is referred to.
