Described is reciprocating motion to a slide requiring a longer stroke than could be produced by conventional CAM design in a limited area.
reciprocating motion to a slide requiring a longer

CAM 1 keyed
(snaps on) to pawl 2 axis, rotates in the direction
indicated. Four roller followers 3, 4, 5 and 6 assembled on the
in-face side of the slide 7, are equally spaced on the center line
(followers are shown on CAM 1 for visual effect). Rotation of the
CAM 1 causes rollers 3 and 4 on opposite sides of track A to follow
the track. When the roller 3 reaches the periphery of A, it ceases
to function as a CAM follower, but motion of the slide 7 is continued
by rollers 4 and 5 on track B, rollers 5 and 6 on track C. The slide
reaches its extreme end with rollers 5 and 6 at the peak of track C.
The pawl 2
after attachment to its host 8, does not rotate. On
the out-face of the CAM 1 are pockets into which appendages 9 of the
pawl 2 snap into (pockets are an integral part of CAM 1 althrough
shown separately). Rotation of the CAM 1 initiates flexing of
appendages and a uniform controlled downward stroke of the slide 7
with locking intervals. Dovetail followers 10 attached to the slide
7 through screws orient the slide to host 8 possessing a matching
dovetail configuration (Fig. 1). Assembled, slide 7 with-snap on
capabilities is progressively attached where applicable (Fig. 2).
