Abstract

An adjustable telescope alignment apparatus employs a telescopic assembly which is secured about the periphery to a pivot ring. The telescopic assembly extends from the front and back surfaces of the pivot ring. The pivot ring is positioned within a inner peripheral channel of a collet member to form a ball and socket joint. The collet member has an outer threaded area which is engaged by a threaded locking ring which locking ring selectively compresses the collet member. By means of the ball and socket joint one can adjust and move the telescope assembly within a desired cone of rotation. The collet member is inserted within an aperture formed in a carrier lens held by a spectacle frame and is secured to the lens by means of a suitable adhesive as applied to an outer peripheral flange of the collet member.
