Inventor: Horel, Thomas B.

Location: Calgary

Comments: N/A

Description: 1. A post domer comprising a doming station, a cutter head rotatably mounted in said doming station, means to deliver individual posts to said doming station, means to rotate and axially advance said post toward said cutter head in said doming station whereby said cutter head cuts a domed surface on one end of said post and means to eject the domed post from said doming station.

2. A post domer as defined in claim I wherein said means to rotate and axially advance comprises an arm, a pair of rolls on said arm, means to drive one of said rolls, said rolls being canted at an angle to the longitudinal axis of a post in said doming station, means to pivotably mount said arm whereby said rolls move into contact with said post in said doming station and said one of said rolls rotate said post to helically advance said post.

3. A post domer as defined in claim 2 wherein said doming station includes means to rotatably support a post being domed, said means to rotatably support includes a pair of supporting rolls adapted to contact the undersurface of a post said supporting rolls being canted at an angle to the longitudinal axis of the post in the doming station substantially equal to the angle on which said pair of rolls are canted.

4. A post domer as defined in claim 3 wherein said pair of rolls and said pair of supporting rolls are pneumatic tires.

5. A post domer as defined in claim 3 wherein means to deliver the posts to said doming station comprises a chain conveyor mounted on said arm, said chain conveyor engaging the upper surface of a post being delivered to said doming station and wedging said post against a supporting surface said chain conveyor contacting and moving said logs toward said doming station, said movement of said post toward said doming station lifting said chain conveyor and thus said arm to permit said post being delivered to enter said doming station beneath said driven roll.

6. A post domer as defined in claim 3 wherein said ejection mechanism comprises a pair of spaced arms, means biasing said arms to ejection position and means for tripping said ejection mechanism to swing said arms to eject a post from said doming station.

7. A post domer as defined in claim 5 wherein said ejection mechanism comprises a pair of spaced arms, means biasing said arms to ejection position and means for tripping said ejection mechanism to swing said arms to eject a post from said doming station.

8. A post domer as defined in claim 7 wherein said means for tripping is actuated by said post being delivered when said arm is lifted to 'permit said post being delivered to enter said doming station.

9. A post domer as defined in claim 1, 2 or 3 wherein said cutter head rotates on an axis substantially parallel to and spaced from the longitudinal axis of said post.

10. A post domer as defined in claim 6, 7 or 8 wherein said cutter head rotates on an axis substantially parallel to and spaced from the longitudinal axis of said post.
