Claims
- 1. Apparatus for positioning and clamping a pair of posts at right angles to each other comprising
- a body member having a pair of offset passages extending therethrough at right angles to each other, each of said offset passages comprising a minor bore portion and a major bore portion,
- a first clamp member having a first bore for receiving one of said posts,
- means on said first clamp member for selectively gripping said one post thereby preventing movement of said one post relative to said first clamp member,
- means for mounting said first clamp member for rotation in one of said major bore portions,
- means on said body member for selectively gripping said one post thereby preventing movement of the same relative to said body member,
- a second clamp member having a second bore for receiving the other of said posts,
- means on said clamp member for selectively gripping said other post thereby preventing movement of said other post relative to said second clamp member,
- means for mounting said second clamp member for rotation in the other of said major bore portions, and
- means on said body member for selectively gripping said other post thereby preventing movement of the same relative to said body member.
- 2. Apparatus as claimed in claim 1 wherein
- said first and second clamp members comprise collars having bosses thereon extending into the major bore portions of said passages, and
- means for retaining said bosses in said major bore portions for rotational movement while preventing translational movement of each of said clamp members relative to said body member.
- 3. Apparatus as claimed in claim 2 including a pair of retaining rings for engaging the bosses on the collars for retaining the same for rotational movement while preventing translational movement of the collars relative to the body member.
- 4. Apparatus as claimed in claim 3 including a circumferential recess on each of said bosses for engaging said retaining rings.
- 5. Apparatus as claimed in claim 3 including means on said body member for gripping each of said posts to restrict rotational and translational movement of said each post relative to said body member.
- 6. Apparatus as claimed in claim 4 including means on each of said collars for gripping one of said posts to restrict movement of said one post relative to said each collar.
- 7. In apparatus for positioning and clamping a pair of posts at right angles to each other of the type having a body member with offset passages at right angles to each other for receiving the posts wherein each of said offset passages comprises a minor bore portion aligned with a major bore portion and a pair of collars for clamping the posts adjacent to the body member, the improvement comprising
- a boss on each of said collars adapted to be inserted into one of said major bore portions of said passages, and
- means for retaining said bosses in said major bore portions of said passages for rotational movement while preventing translational movement of said collars relative to said body member.
- 8. Apparatus as claimed in claim 7 including a pair of retaining rings for engaging the bosses on the collars for retaining the same for rotational movement while preventing translational movement of the collars relative to the body member.
- 9. Apparatus as claimed in claim 8 including a circumferential recess on each of said bosses for engaging said retaining rings.
- 10. Apparatus as claimed in claim 8 including means on said body member for gripping each of said posts to restrict rotational and translational movement of said posts relative to said body member.
- 11. Apparatus as claimed in claim 9 including means on each of said collars for gripping one of said posts to restrict movement of said one post relative to said each collar.
- 12. An improved clamp comprising
- a body having a pair of offset passages extending therethrough at right angles to each other, each of said offset passages comprising a minor bore portion aligned with a major bore portion,
- a first collar adjacent to one of said passages,
- a second collar adjacent to the other of said passages,
- a boss on each of collars adapted to be inserted into one of said major bore portions of said passages, and
- means for retaining said bosses in said major bore portions of said passages for rotational movement while preventing translational movement of said collars relative to said body.
- 13. Apparatus as claimed in claim 12 including a pair of retaining rings for engaging the bosses on the collars for retaining the same for rotational movement while preventing translational movement of the collars relative to the body.
- 14. Apparatus as claimed in claim 13 including a circumferential recess on each of said bosses for engaging said retaining rings.
