摘要： A hand-held device for measuring the curvature of cylindrical or toroidal surfaces such as optical lenses. A longitudinally movable plunger or spindle extends from a rotationally adjustable indicator dial with its work-contact end bisecting a transverse support frame which carries a parallel pair of work-contact buttons spaced apart by the length of a chord of the curved work surface whose midspan is to be contacted by the plunger. The consequent dial read-out is a factor (in mm.) from which the curvature of the arc can be obtained, as by reference to tabulated data. The support frame is detachable from the indicator unit and a progressive series of such frames having buttons spaced apart by different chord lengths are provided for measuring both convex and concave workpieces of different curvatures. The pair of work-contact buttons are flat-ended cylinders which make point contact of an edge of the cylinder with an arcuate workpiece; when worn, such contact points can be shifted by rotating the button in the frame and thus maintain extreme precision of the instrument.

摘要： A lens grinding and polishing unit wherein either the workpiece or lap is supported by a laterally oscillatable head and the other is held atop a non-rotating flexible spindle (e.g. aluminum) which is simultaneously flexed at different speeds and courses in a repetative pattern compounded by rotation thereabout of (a) an inner tubular housing which eccentrically embraces the spindle at a circumference intermediate its length, and (b) an intermediate tubular housing spaced outward from the inner housing and which eccentrically bears on the inner housing adjacent the same circumferential area, separated from the inner housing by a ball bearing raceway. The intermediate housing is outwardly surrounded by a fixed housing from which it is separated by another ball bearing raceway, and all three generally concentric housings are mounted within an outermost dome of somewhat flexible material, the dome being supportingly transected by the spindle at a circumference between the carried lap and the top of the inner rotatable housing, so as to be jointly flexed by oscillation of the spindle. Both rotatable housings are pulley-operated from an electric motor which also oscillates the head (carrying the workpiece), thus totally eliminating cam and gear mechanisms previously employed in polishers. Adjacent units located in a cabinet can be operated by a single motor. Such units also carry a pneumatic element to supply down-pressure for the head, and provide circulation of lubricating fluid to the lap.
