distributing rollers during operation of the press. More particularly, means are provided
for selectively changing the location of the first pivot 29, and thereby, the manner in
which the rocker member 26 acts on the lever 34 in response to driving movement of
the link 21. As best seen from viewing Figures 1 and 2, the amplitude of the
reciprocating movement of the rocker 26 depends upon the location of the rocker pivot
29. Thus, the magnitude of the oscillations of the lever 34 can be varied by adjusting
the location of the rocker pivot 29. To this end, the two-armed lever 28 is rotatably
mounted on a support shaft 55. To rotate the lever 28 about the shaft 55, a threaded
spindle 58 is captively mounted on the frame 11 by means of a bracket 59 secured to
the frame 11 by bolts 60. The spindle 58 is rotatably maintained in the bracket 59 by
means of bushings 61 and a snap ring 62. A traveling nut 64 is threadably received on
the spindle 58 so as to be movable along the length of the spindle 58 in response to the
rotation thereof. A threaded stud 65 extends from the nut 64 through the arm 28b of
the lever 28 and is secured thereto by a nut 66. Thus, as the traveling nut 64 moves
along the length of the threaded spindle 58 in response to rotation of the spindle, the
lever arm 28b, and thus the lever 28, will rotate about the axis of the shaft 55.
Consequently, the arm 28a of the lever 28 will rotate about the axis of the support shaft
55 to adjust the location of the rocker pivot 29. To facilitate the manual rotation of the
threaded spindle 58, a knob 68 is secured to the spindle 58 externally of the press
frame. The knob 68 may have graduations thereon so that the press operator can
