Application No. 09/213,726
For axially reciprocating the distributing rollers 15a-d, a press drive 18 rotates a
shaft 19 supported by a bushing 20 externally-mounted on the frame. A link 21 is
eccentrically mounted to the end of the drive shaft 19 by a bolt 22, washers 24 and
bushing 25 so that the link 21 is pivotable with respect to the drive shaft 19. A rocker
member 26 in turn is pivotally coupled to the end of the link 21, being mounted on a pin
31 carried on the end of the link 21 with bushings 32 interposed therebetween to
facilitate relative movement. The rocker member 26 also is mounted for relative pivotal
movement with respect to one arm 28a of a two-armed lever 28, being mounted on a
first pivot or pin 29 fixedly held in the lever arm 28a with bushings 30 interposed
therebetween. A lever 34 is pivotally mounted in the side column 12 by means of a
second pivot 35 and bearings 36. To oscillate the lever 34 about the axis of the second
pivot 35, the lever 34 has a sled or block 38 which is captively held in an elongated slot
39 in the rocker 26. Hence, as the rocker 26 pivots about the axis of the first pivot 29 in
response to the oscillation of the link 21 effected by rotation of the shaft 19, the lever 34
will oscillate about the second pivot 35 with the block 38 sliding back and forth in the
slot 39. The oscillating lever 34 is operatively connected to the rollers 15a-d such that
the rollers are axially reciprocated as a result of oscillating movement of the lever 34.
In accordance with an important aspect of Hummel's invention, means are
provided for selectively adjusting the magnitude of the axial reciprocation of the
