A breaker mechanism for repair of a fire hydrant upon impact, wherein the fire hydrant comprises a hollow upper barrel comprising an outer bottom ledge, an upper stem located on a center axis of the upper barrel, a hollow lower barrel comprising an upper flange, and a lower stem located on a center axis of the lower barrel, comprising:
- a) two half-moon shaped breaker rings shaped to sit on the outer bottom ledge of the upper barrel and having a plurality of holes;
- b) two curved breaker straps having a plurality of holes and shaped to connect the two breaker rings, wherein the holes are placed to line up with outermost holes of the breaker rings and holes in the upper flange;
- c) a stem breaker coupling partially located within the upper barrel and partially located within the lower barrel that couples the upper stem to the lower stem such that a bottommost portion of the upper stem and a topmost portion of the lower stem are located within a hollow chamber of the breaker coupling;
- d) a first coupling pin to connect the stem breaker coupling to the upper stem;
- and
- e) a second coupling pin to connect the stem breaker coupling to the lower stem.
A collision repair kit for a fire hydrant comprising a hollow upper barrel comprising an outer bottom ledge, an upper stem located on a center axis of the upper barrel, a hollow lower barrel comprising an upper flange, and a lower stem located on a center axis of the lower barrel, the collision repair kit comprising:
- a) two half-moon shaped breaker rings shaped to sit on the outer bottom ledge of the upper barrel and having a plurality of holes;
- b) two curved breaker straps shaped to connect the two breaker rings, wherein the holes are placed to line up with outermost holes of the breaker rings and holes in the upper flange;
- c) a stem breaker coupling that couples the upper stem to the lower stem such that a bottommost portion of the upper stem and a topmost portion of the lower stem are located within a hollow chamber of the breaker coupling;
- d) a first coupling pin to connect the stem breaker coupling to the upper stem;
- and
- e) a second coupling pin to connect the stem breaker coupling to the lower stem.
A method of repairing a fire hydrant after an impact, wherein the hydrant comprises a hollow upper barrel comprising an outer bottom ledge, an upper stem located on a center axis of the upper barrel, a hollow lower barrel comprising an upper flange, a lower stem located on a center axis of the lower barrel, and a breaker mechanism comprising two half-moon shaped breaker rings shaped to sit on the outer bottom ledge of the upper barrel and having a plurality of holes, two curved breaker straps having a plurality of holes and shaped to connect the two breaker rings, wherein the holes are placed to line up with outermost holes of the breaker rings and holes in the upper flange, a stem breaker coupling that couples the upper stem to the lower stem such that a bottommost portion of the upper stem and a topmost portion of the lower stem are located within a hollow chamber of the breaker coupling, a first coupling pin to connect the stem breaker coupling to the upper stem, and a second coupling pin to connect the stem breaker coupling to the lower stem, the method comprising the steps of:
- a) removing a broken stem breaker coupling, the breaker straps and the breaker rings;
- b) installing a new stem breaker coupling;
- and
- c) reassembling the fire hydrant.
