  • Patent number: 4488792
    Abstract: An eyeglass assembly having removable temple pieces. A spring arm has on one end a hinge pin and on the other end means for mounting the arm on the temple piece. The arm is shiftable between an advanced position wherein the pin unites the knuckles to form a hinged connection, thereby attaching the temple pieces to the front frame piece, and a retracted position wherein the pin is removed from the knuckles. This detaches the temple pieces from the front frame piece and enables use of the latter separately, for example, in a gas mask where the temple pieces would interfere with the proper placement of the mask.
