Abstract
Abstract An ophthalmic lens centering and mounting device includes a base which receives and centers the ophthalmic lens. A support receives a holding and securing device for the lens in a removable way and is carried by an arm mounted to swing on the base to apply the holding and securing device to the ophthalmic lens. A barrel mounted to rotate on the arm carries the support. A template support carried by the barrel receives in a removable way a template that has to be superposed on the lens before the holding and securing device is placed on the lens.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
156 words
An ophthalmic lens centering and mounting device comprising a base including means to receive and center an ophthalmic lens, an arm swingingly mounted on the base between on operative position wherein said arm is proximate said base and on inoperative position wherein said arm is remote from said base, a barrel rotatably mounted on said arm, said barrel carrying a template support on a first portion of the barrel for removably mounting a template to be superposed on the ophthalmic lens for centering the same, said barrel further carrying a support on a second portion of the barrel for removably mounting holding and securing means for holding and securing the ophthalmic lens, said barrel rotatably selectively positioning either said support or said template support in alignment to the lens, whereby said arm may be moved to said operative position to allow engagement of said holding and securing means or superposition of said template on said lens.
