Appeal No. 95-4860 Application No. 08/044,923 relative to the first shift 11 or (2) the second pressure plate 41 was rotated so that it would advance along the threads 19 on the end of the second shaft 12. There is, however, no enabling disclosure of a mechanism which would accomplish either of these alternatives. To the contrary, the specification sets forth it is the hexagonal nut 48 (which is received in a hexagonal recess 47 in the second pressure plate 41) which is threadably engaged with the threads 19 (see page 9, lines 13-21) and, in describing the interaction between these elements, states that: The rotation of inner shaft 12 causes threads 19 on the interior end thereof to be advanced within nut 48. The advancement of nut 48 and threads 19 decreases the distance between front pressure plate 41 and rear pressure plate 40. [Page 11, lines 3-6; emphasis ours.] The above description clearly describes the nut 48 as being threadably coupled to the shaft 12 and further suggests that the pressure plate 41 is simply loosely mounted on shaft 12 so that advancement of the nut 48 along threads 19 will cause the pressure plate 41 to be moved toward pressure plate 42. Claims 18-22 are rejected under 35 U.S.C. § 112, second paragraph.
