Appeal No. 2001-2361
Application No. 09/411,369
restrained from rotation relative to the barrel and each other.
The pencil also includes an eraser support member provided on a
back portion of the adapter. On pages 19-22 of the
specification, appellants describe an embodiment of their
invention (e.g., Figs. 12-13) wherein the adapter (3) is said to
have an "expanded front end portion" (3x) and to include
longitudinal ribs (3y) on the outer circumference of said
expanded front portion to cooperate with longitudinal grooves
(1yy) on the barrel (1) of the pencil, so as to restrain the
adapter from rotation relative to the barrel while permitting
axial movement thereof relative to the barrel. It would appear
that the embodiments of appellants' invention seen in Figures 14
through 17 also include an "expanded front portion" (3x) on the
adapters (3) therein similar to that seen in Figures 12 and 13.
A primary object of appellants' invention is to prevent the
torsional breakage of a lead held by the front and back chucks,
particularly when the eraser (E) is being used. A copy of claims
1 through 3 on appeal may be found in Appendix A of appellants'
brief.
