DEFINITION

Classification: 335/286

(under subclass 285) Subject matter including means adapted to be placed between the magnet and the workpiece or the object being held by the magnet.

(1) Note. The adaptor may be made of a nonmagnetic material and be used merely to prevent, for example, the workpiece from rocking, or it may be of magnetic material and be used to bridge the flux from the magnet into the workpiece.

(2) Note. This subclass also includes magnetic chucks that are angular in shape to facilitate holding the workpiece.
