DEFINITION

Classification: 269/47

(under the class definition) Device wherein the work holder has a portion which is adapted to be positioned within a preformed opening in the work and, when so positioned, is peripherally encompassed by the work.

(1) Note. The opening need not extend completely through the work.

(2) Note. A holder for a wound up roll of material is not considered to meet the definition of this subclass unless the teaching of the patent is that the work is treated in wound up roll form; also see the class definition.

(3) Note. For a patent to be placed as an original in this subclass, the holder portion insertable within the work aperture, or a holder part receiving such portion, must be claimed. For example, a patent to a work holder disclosed as having work bolted thereto by a bolt extending through an opening in the work and extending through an opening in the holder will be placed as an original in this subclass only if the bolt or the bolt receiving opening in the holder is claimed.

(4) Note. Included in this an indented subclasses are devices to which a workpiece is secured by embracing a part of the holder, e.g., using the clamp of an outboard motor to mount said motor on a holder.
