Abstract

The present disclosure relates to the construction and use of feedlines in temperature-biased systems that include counter-biased hoses. The alignment and installation/uninstallation of the counter-biased hoses is enabled by a biasing tool with at least a first yoke having a first rotation point and a second rotation point, a second yoke having a third rotation point and a fourth rotation point, a first rod assembly connected to the first yoke at the first rotation point and connected to the second yoke at the fourth rotation point, and a second rod assembly connected to the first yoke at the second rotation point and connected to the second yoke at the third rotation point.

First claim

What is claimed is:

1. A biasing tool, comprising:
a first yoke having a first rotation point and a second rotation point;
a second yoke having a third rotation point and a fourth rotation point;
a third yoke having a fifth rotation point and a sixth rotation point;
a fourth yoke having a seventh rotation point and an eighth rotation point on an opposite surface from the third rotation point and the fourth rotation point
a first rod assembly connected to the first yoke at the first rotation point and connected to the second yoke at the fourth rotation point, the first rod assembly having a first length;
a second rod assembly connected to the first yoke at the second rotation point and connected to the second yoke at the third rotation point, the second rod assembly having a second length independent from the first length, the second rod assembly having a non-parallel arrangement relative to the first rod assembly;
a third rod assembly connected to the third yoke at the fifth rotation point and connected to the fourth yoke at the eighth rotation point, the third rod assembly having a third length;
a fourth rod assembly connected to the third yoke at the sixth rotation point and connected to the fourth yoke at the seventh rotation point, the fourth rod assembly having a fourth length;
wherein the third yoke is matched with the first yoke to form a first collar;
wherein the fourth yoke is matched with the second yoke to form a second collar;
wherein the third rod assembly is parallel to the first rod assembly and the third length is matched to the first length; and

wherein the fourth rod assembly is parallel to the second rod assembly and the fourth length is matched to the second length.

2. The biasing tool of claim 1 , further comprising:
the first collar having a first latch on a first side of the biasing tool and a first hinge on a second side of the biasing tool opposite to the first side; and
the second collar having a second latch on the first side and a second hinge on the second side.

3. The biasing tool of claim 1 , further comprising:
the first collar having a first latch on a first side of the biasing tool and a second latch on a second side of the biasing tool opposite to the first side; and
the second collar having a third latch on the first side and a fourth latch on the second side.

4. The biasing tool of claim 1 , wherein the first collar defines a first through-hole in a first plane; and wherein the second collar defines a second through-hole in a second plane parallel to the first plane.

5. The biasing tool of claim 4 , wherein the first length and the third length are adjustable to laterally bias a hose captured in the first through-hole and the second through-hole.

6. The biasing tool of claim 5 , wherein the second length and the fourth length are adjustable to longitudinally bias the hose captured in the first through-hole and the second through-hole.

7. The biasing tool of claim 1 , wherein the first rotation point and the fourth rotation point contain movement of the first rod assembly to rotation in a first plane, and wherein the second rotation point and the third rotation point contain movement of the second rod assembly to rotation in a second plane parallel to the first plane.

8. The biasing tool of claim 1 , wherein the first yoke includes a first hose grip, and wherein the second yoke includes a second hose grip.

9. The biasing tool of claim 1 , further comprising:
a first sliding yoke connected via a first sliding lug to the first yoke to selectively slide laterally relative to the first yoke, wherein the first sliding lug selectively secures the first sliding yoke to the first yoke to restrict movement of the first sliding yoke; and
a second sliding yoke connected via a second sliding lug to the second yoke to selectively slide laterally relative to the second yoke, wherein the second sliding lug selectively secures the second sliding yoke to the second yoke to restrict movement of the second sliding yoke.

10. The biasing tool of claim 1 , further comprising:
a first mobile yoke connected via a first pivot to the first yoke;
a first height lug disposed of in the first yoke in contact with the first mobile yoke, configured to affect a height of a portion of the first mobile yoke relative to the first yoke;
a second mobile yoke connected via a second pivot to the second yoke; and
a second height lug disposed of in the second yoke in contact with the second mobile yoke, configured to affect a height of a portion of the second mobile yoke relative to the second yoke.

11. A biasing tool, comprising:
a first turnbuckle having a first end and a second end;
a second turnbuckle having a first end and a second end;
a first collar defining a first through-hole in a first plane and including a first rotation point that rotates in a second plane and a second rotation point rotates in a third plane, wherein the second plane and the third plane are perpendicular to the first plane;
a second collar defining a second through-hole in a fourth plane parallel to the first plane and including a third rotation point that rotates in the second plane and a fourth rotation point that rotates in the third plane;
wherein the first end of the first turnbuckle is connected to the first rotation point;
wherein the second end of the first turnbuckle is connected to the second rotation point;
wherein the first end of the second turnbuckle is connected to the third rotation point;
wherein the second end of the second turnbuckle is connected to the fourth rotation point; and
wherein the first turnbuckle crosses the second turnbuckle.

12. The biasing tool of claim 11 , further comprising:
the first collar further including a fifth rotation point that rotates in a fifth plane and a sixth rotation point rotates in a sixth plane, wherein the fifth plane and the sixth plane are perpendicular to the first plane;
the second collar further including a seventh rotation point that rotates in the sixth plane and an eighth rotation point rotates in the fifth plane;
a third turnbuckle having a first end connected to the fifth rotation point and a second end connected to the eighth rotation point, parallel to the first turnbuckle;
a fourth turnbuckle having a first end connected to the sixth rotation point and a second end connected to the seventh rotation point, parallel to the second turnbuckle.

13. The biasing tool of claim 11 , further comprising:
the first collar further including a first yoke, a second yoke, and a first latch, the first yoke defining a first portion of the first through-hole and the second yoke defining a second portion of the first through-hole, the first latch securing the first yoke with the second yoke; and
the second collar further including a third yoke, a fourth yoke, and a second latch, the third yoke defining a first portion of the second through-hole and the second yoke defining a second portion of the second through-hole, the first latch securing the third yoke with the fourth yoke.

14. A biasing tool, comprising:
a first yoke having a first rotation point and a second rotation point;
a second yoke having a third rotation point and a fourth rotation point;
a third yoke having a fifth rotation point and a sixth rotation point;
a fourth yoke having a seventh rotation point and an eighth rotation point on an opposite surface from the third rotation point and the fourth rotation point;
