Application No. 10/087,613
Appellants argues that Steffens does not describe that the rocker arms 94, 96,
98, and 100 are movable between an operative and inoperative position. We agree.
Steffens describes and depicts in Figures 1 and 2, rocker arms 94, 96, 98 and
100 allow the rollers 34, 40, 46 and 48 to moved translationally parallel to the plates 24,
36, 42 and 44 respectively. Steffens teaches that this translation movement of the
rollers 34, 40, 46 and 48 will allow these rollers to be displaced in these translational
directions to avoid a paper jam when a thicker paper is utilized without interference from
the leading edges of the fold plates 24, 36, 42 and 44 (col. 4, lines 15 to 27). Each
roller has a:
. . . roller positioning apparatus. The head 84 on the adjusting screw 72
limits the travel of clockwise rotation of the rocker arm 94, while resilient
sleeve 80 acts to restrict the counterclockwise rotation of the rocker arm
94 with a force equal to the preload set up in the sleeve by the locking
collar 90 [col. 4, lines 8 to 14].
As such, the collar 90 is utilized to adjust the magnitude of bias of the resilient
sleeve 80. Steffens does not describe that collar 90 may be adjusted to move the rocker
arms between an operative and an inoperative position. The pivoting of the rocker arms
is between two operative positions so as to avoid a paper jam. Even if the rocker arms
were adjusted to the maximum extent, such would not move the rocker arms to an
inoperative position because the rocker arm would still be held operative by operation of
screws 70,72, 76, 78.
