Abstract From the Canadian patent
A slingshot releaser including a clamp which stably, holds a pouch attached to an elastic band and a pellet. The clamp has two rotatable holding rollers arranged on the distal ends of two arms. Each holding roller 17 has a peripheral surface including a support groove 21 and support rings 22, which are arranged perpendicular to the roller axis. The clamp has a pouch holder defined between the arms to hold the pouch when the clamp is closed. A lever is operated to open the clamp. This flings the pellet out of the clamp with the elastic force of the elastic band as the pouch and the pellet rotate the holding rollers.

Why it's free to use
- Filed May 8, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended May 8, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 8, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
