Abstract

1,251,961. Spectacle frames. P. R. LAGUE and A. DYNES. Jan. 6, 1969 [Jan. 4, 1968], No. 571/68. Heading G2J. In a spectacle frame wherein the eye-pieces are made as seperate pieces each having at its nasal margin a tongue and a slot so that the tongue of the one frame eye-piece fits into the slot of the other, there is provided a bridge 16 having nibs 17, 17a therewithin which are engageable with notches formed between transverse ribs located within longitudinally extending grooves in the outer surfaces of the tongues. Relative outward movement of each tongue and hence each lens frame is limited by an appropriate nib/rib abutment whilst relative inward tongue movement is limited by "stepping" the outer surface of tongue 11a so that only a thinner portion 11b is locatable within slot 12.
