Open the CIPO recordAbstract From the Canadian patent
The steady-rest is solid and rigid by virtue of the fact that the rest encircles the workpiece, and is tightly gripped thereto. The steady-rest is clamped tightly to the slideway rails of the lathe. As such, the rest supports the workpiece against cutting forces, and against vibrations and bouncing of the workpiece as it rotates.

Why it's free to use
- Filed July 21, 1997. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 21, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 21, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
