Open the CIPO recordAbstract From the Canadian patent
An adjustable feeder includes a first arrangement which acts as a dry feeder and provides two vertical slides (31) each on a respective side of a hopper (22) which is simultaneously vertically adjustable by straps (41) at the ends of the hopper. In a second arrangement the same adjustment system is used with a shelf type feeder so that the shelf (60) can be adjusted between a lower position for small animals and a raised position for large animals and the slides (31) can move vertically to accommodate the change in height of the shelf (60) and to adjust the distance of the slides (31) from the shelf (60) to control the feed flow.

Why it's free to use
- Filed January 25, 1996 and granted July 30, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended January 25, 2016.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 25, 2018.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
