Open the CIPO recordAbstract From the Canadian patent
The driving mechanism has a drive shaft which rotates a driving block. A cam is mounted for rotation to the driving block and is received in a slot of a follower. As the cam rotates it rolls backwards and forwards in the slot and causes the follower to rotate. A connecting rod is affixed to the follower and i.s rotated by it. The connecting rod rotates about an axis parallel to but offset from, the axis about which the drive shaft rotates. The rate of rotation of the drive shaft is unvarying whereas the connecting rod rotates at a varying rate. A crank is affixed to the connecting rod and imparts reciprocating motion to the tray. A link can be substituted for the cam.

Why it's free to use
- Filed July 12, 2000 and granted July 5, 2011. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended July 12, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 12, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
