Abstract of the Disclosure, There is disclosed a camming apparatus for a work station that provides for relative rotational motion between a cam and a cam follower connected to the work station, e.g. a liquid dispenser. The cam follower is movable on a carrier that frictionally engages the cam, unless the carrier is restricted. The cam is rotated by a gear. A locking mechanism is provided to lock the carrier against inadvertent rotation, and the improvement resides in the locking mechanism comprising a gear segment on the cam follower positioned to engage the gear during a portion of the engagement by the drive gear of the gear segment on the cam.

Why it's free to use
- Filed February 11, 1992. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended February 11, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 11, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
