Abstract

A fire hydrant drain includes an elongated, hollow body having a first portion, a second portion, and a third portion. The first portion is configured to protrude a first length radially through an outer wall of a fire hydrant. The second portion is continuous with and between the first portion and the third portion. The second portion includes a first bend having a first curvature degree and a first curvature direction, and a second bend having a second curvature degree and a second curvature direction. The first curvature degree is larger than the second curvature degree, and a direction of the first curvature is opposite a direction of the second curvature. The first bend is between the first portion and the second bend. The third portion extends a second length, and an angle between the first length and the third length is less than 90 degrees.

First claim

What is claimed is:

1. A fire hydrant drain comprising:
an elongated, hollow body having a first portion, a second portion, and a third portion,
the first portion protruding radially through an outer wall of a fire hydrant and protruding outward from the fire hydrant,
the second portion continuous with and between the first portion and the third portion, the second portion including a first bend and a second bend, the first bend between the first portion and the second bend, the first bend and the second bend configured to direct the third portion to extend along an inner surface of the outer wall of the fire hydrant and to press into the inner surface with a pressing force,
the third portion being held in place by the pressing force against the inner surface.

2. The fire hydrant drain of claim 1 , wherein the fire hydrant includes an upper barrel and a lower barrel, and the third portion traverses the upper and lower barrel of the fire hydrant.

3. The fire hydrant drain of claim 1 , wherein the fire hydrant includes an upper barrel and a lower barrel, the inner surface of the fire hydrant includes an upper barrel inner surface and a lower barrel inner surface, and the third portion presses most strongly into the inner surface of the fire hydrant at the upper barrel inner surface.

4. The fire hydrant drain of claim 1 , wherein the fire hydrant includes an upper barrel and a lower barrel, the inner surface of the fire hydrant includes an upper barrel inner surface and a lower barrel inner surface, and the third portion presses most strongly into the inner surface of the fire hydrant at the lower barrel inner surface.

5. The fire hydrant drain of claim 1 , wherein an end of the third portion distal from the second portion is curved away from the outer wall of the fire hydrant.

6. The fire hydrant drain of claim 1 , wherein the pressing force is greater than 50 Newtons.

7. The fire hydrant drain of claim 1 , wherein the first bend curves more than 90 degrees and the second bend curves less than 90 degrees.

8. A fire hydrant drain comprising:
an elongated, hollow body having a first portion, a second portion, and a third portion,
the first portion configured to protrude a first length radially through an outer wall of a fire hydrant,
the second portion continuous with and between the first portion and the third portion, the second portion including a first bend having a first curvature degree and a first curvature direction, and a second bend having a second curvature degree and a second curvature direction, the first curvature degree larger than the second curvature degree, a direction of the first curvature opposite a direction of the second curvature, the first bend between the first portion and the second bend,
the third portion extending a second length,
an angle between the first length and the third length being less than 90 degrees.

9. The fire hydrant drain of claim 8 , wherein the first length is straight.

10. The fire hydrant drain of claim 8 , wherein the second length is longer than the first length.

11. The fire hydrant drain of claim 8 , wherein a center axis of the first portion, the second portion, and the third portion are in the same plane.

12. The fire hydrant drain of claim 8 , wherein the elongated, hollow body is a tube.

13. The fire hydrant drain of claim 12 , wherein the tube has a circular cross section.

14. The fire hydrant drain of claim 8 , wherein the first bend curves more than 90 degrees and the second bend curves less than 90 degrees.

15. A fire hydrant comprising:
an upper barrel, the upper barrel having an outer wall, and inner surface of the outer wall, and an opening through the outer wall;
a drain tube having a first portion, a second portion continuous with the first portion, and a third portion continuous with the second portion,
the first portion extending through the opening through the outer wall,
the second portion including a first bend and a second bend, the first bend connected to the second bend,
the third portion extending from the second bend at an acute angle greater than 0 degrees toward the inner surface of the outer wall of the upper barrel.

16. The fire hydrant of claim 15 , wherein the third portion presses into the inner surface of the outer wall of the upper barrel with a pressing force.

17. The fire hydrant of claim 15 , further comprising a lower barrel connected in line with the upper barrel, the lower barrel having an outer wall, the outer wall having an inner surface, the third portion pressing into the inner surface of the outer wall of the lower barrel with a pressing force.

18. The fire hydrant of claim 15 , wherein the first portion extends directly radially outward from the outer wall of the upper barrel, the first bend curves more than 90 degrees, and the second bend curves less than 90 degrees.

19. The fire hydrant of claim 15 , further comprising a lower barrel connected in line with the upper barrel, the lower barrel having a cylindrical outer wall entirely continuous and solid.
