Abstract

908,546. Engraving. MORGAN FAIREST Ltd. March 16, 1961 [Feb. 16, 1961], No. 5725/61. Class 100 (2). An engraving needle for an electric engraving machine comprises a tubular stem and a length of wire fitting the length of the bore of the stem and protruding from the bore at at least one end, the stem being compressed into a section that provides at least one longitudinal V-edge to bed in the V-groove of the vibrating block of the engraving machine, the compression also serving to grip the wire within the bore. The wire B, Figs. 3 and 5, passes through the bore 3 of the stem A with some clearance and protrudes at both ends to provide a reversible needle. The stem A is compressed along a length 1 into an equilateral triangular section, causing the bore to grip the wire, except near its ends, where cylindrical heads 2 remain, which limit the downward movement, to compensate for consumption of the working end of the wire, of the stem in the vibrating block 7, Fig. 2, one V-edge of the stem being held in a groove 6 in the block by a spring clip 11.
