Abstract

512,419. Moulding spectacle frames. TWINCO, Ltd., and LAUGHTON, M. Feb. 1, 1938, No. 3074. [Class 87 (ii)] [Also in Group XX] Each eye part c of a spectacle or goggle frame is pressed or moulded with a ledge b upon which the lens or other transparent panel e is placed and with an upstanding rim d around the ledge, the rim being subsequently pressed over while in a plastic condition so as to lie adjacent to and secure the lens in position. The frame may be moulded from synthetic resin or cellulose acetate- or other derivative. The rim d is pressed over between a punch h and a die g. The rim may be still warm from the initial moulding or may be softened by heat or other means. The punch h is formed with stop means to prevent undue pressure and breakage of the lens. The ledge b is so directed as to be accessible from the front of the frame and the rim d preferably extends continuously around the ledge.
