    摘要： A copying machine, in this case a lathe, includes a set of roughing stops carried on an indexable hub, and a fixed finishing stop. A rotary hydraulic motor is provided between a rod on which the template is rockably supported and a lever which is adapted to contact one of a series of roughing stops carried by a hub. The rod carrying the template also carries a second lever arranged to contact a micrometric finishing stop, so that the swinging of the template about the axis of the rod is controlled by selection of an appropriate one of the series of roughing stops to be engaged by the first mentioned lever.

    摘要： This device for clamping a templet and a workpiece to be outlined on the opposite ends, respectively, of the rotary spindle of an outline reproduction machine comprises a pair of clamping jaws axially movable towards and away from the relevant ends of said spindle, one jaw being constantly urged by spring means against the adjacent spindle end and the other jaw, in its rest position, being somewhat spaced from the opposite end of said spindle, single clamping control means for controlling the movements of said pair of jaws, and means for locking said clamping control means in the desired position after clamping said templet and workpiece against the opposite ends of said spindle. This invention is applicable more particularly but not exclusively to machines for trimming and bevelling ophthalmic lenses.
