DEFINITION

Classification: 227/19

(under the class definition) Device comprising means to move or guide a workpiece* into juxtaposition with another workpiece, and including (a) means to hold or position a member* between said workpieces before they are moved into juxtaposition or (b) means to hold or position said workpieces in alignment with a driver* for application of a member thereto.

(1) Note. One or both of the workpieces being assembled may be indeterminate-length material.

(2) Note. For placement as an original in this subclass area, a patent must be directed to a member-inserting device with means at least to direct or guide two workpieces or lengths of material into contact at some point and to present such assembled work to the action of a driver. Usually, but not necessarily, the inserted member will serve to secure the workpieces together.

(3) Note. A work stop abutment, disclosed as being useful for facilitating the registry, of two or more workpieces at a driving-station, is insufficient to constitute "means to move or guide a workpiece" under the subclass definition.

(4) Note. A fastener member is not generally regarded as "work", for the purposes of this class. A device provided with means to feed a member to driving position, on or near a workpiece, is not classifiable as an assembly device but is subject matter for the following subclasses 107+. Means for performing an operation on the member (such as cutting, shaping, heading, etc.) is specifically provided for in appropriate subclasses of this class (e.g., subclasses 79+, with means to cut member after penetration).

(5) Note. For the line between this subclass (and those indented hereunder) and classes relating to combined driving and assembly, see section VI of this class definition and for classes relating to assembly, see section VII of this class definition. SEE OR SEARCH CLASS
