Abstract

349,157. Forging nuts. BURNS, H.E., 3403, West 47th Street, Chicago, U.S.A. March 5, 1930, No. 7210. [Class 83 (iv).] Dies.-A lock nut with a deep transverse groove providing a bendable portion a causing the nut to deform when tightened on its bolt is formed from a blank B<1> severed from a hot bar S by the combined cut-off and crowning tool 6 having a transverse rib 6b the shape of the transverse groove in the nut. The tool 6 pushes the blank into the bore 2 of the matrix 1 and coacts with the lower tool 7 in shaping the nut. The latter is then pierced by a punch 9, the punchings P being pushed through the bore 6c of the tool 6 to fall from opening 6d, and the nut is ejected from the matrix 1 by the lower tool 7. Specification 339,159, [Class 89 (i), Bolts &c.], is referred to.
