DEFINITION

Classification: 227/51

(under the class definition) Device including means to deform an end portion of the member in such a manner as to increase the size, and/or to change the form, of the cross-section of said end portion after the member has penetrated the work.

(1) Note. A simple bending or deflecting (i.e., clenching) of a member during or after driving, is not regarded as "heading" for this subclasses (51+). Disclosures of clenching means are to be found in many subclasses throughout the Class 227 schedule; patents directed to this feature are placed as originals in subclass 155.

(2) Note. For the purposes of this subclass (51), the device must deform the member during or at the end of the driving stroke. The shaping or forming of a member prior to its penetration into work is effected by the machines classified in subclasses 82+.

(3) Note. Figure 3 diagrammatically illustrates various means to head a member. [figure] [caption]Fig. 3
