  • Patent number: 4484416
    Abstract: A metallic crossbar device has mounting means for the end regions of spectacle frame yokes and space for a number of adjacent spectacle frames oriented in about the same direction. The cross-bar device comprises two crossbars which run parallel to each other and are spaced apart at a distance corresponding to the spacing of the end regions of the spectacle frame yokes. The crossbars have cross yokes at their end regions which rigidly connect the crossbars together. Each of the crossbars comprises two adjacent, flexurally stiff partial bars and clamping means for clamping one partial bar like a vice against an adjacent partial bar. The partial bars have a maximum clamping height which corresponds to the unprocessed length of the spectacle frame yoke end regions. Both partial bars have strip-shaped plastic clamping linings on their sides adjacent each other.
