Abstract

234,553. Terry, C. Feb. 29, 1924. Rods and bars. - An ornamental head-band for a telephone head-set is made by subjecting a plain metal strip to a pressing or rolling operation to form on it projections and indentations except at the ends 12a, which are left plain to enable them to pivot freely in contact with the ends of a second head-band. The metal used is preferably that known under the registered Trade. Mark " Duralumin," and the strip is shaped to the correct curvature during the pressing and rolling operation.
