Latest Patents

David W. Henry holds a patent for a "Method and apparatus for aligning an ophthalmic lens during a blocking." This invention provides a method and apparatus for aligning a lens blank upon a lens blocking device. The apparatus includes a transparent aligning member, which is attached by arm means to a stanchion on the lens blocking machine. Vertically aligned perpendicular intersecting linear indicia are imprinted upon the upper and lower surfaces of the transparent member for vertically aligning an underlying lens without introducing a parallax error. A lens retaining member is also carried by the stanchion and is selectively pivoted into position to retain the aligned lens blank for blocking. The method consists of rotating a lens blank upon a lens blocking machine until perpendicularly intersecting linear indicia on the surface of the lens are vertically aligned with perpendicularly intersecting indicia on the upper and lower surfaces of a transparent aligning member. Once alignment is achieved, the transparent aligning member is rotated away, and a retaining member is rotated into position to bias the lens blank against the lens blocking apparatus.
