A U-shaped yoke has its intermediate straddle portion received in the slot and its two threaded leg portions extending along either side of the body and protruding through a pair of openings in a saddle member; a pair of nuts are used to tighten the U-shaped yoke and the saddle member so that the tree may be tightly secured in an upright position in the cylindrical body.

Why it's free to use
- Filed April 4, 1990 and granted November 5, 1996. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 4, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 4, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
