Patent ID: 8827320

Claim:
A fire hose connector system comprising: a) an adapter connected to a first end of a fire hose, the fire hose having a second end for attaching to a fire hydrant, b) said adapter comprising a cylinder having a first end, a second end and walls, said first end including a fitting for attachment to a fire hose and said second end comprising a cylindrical quick disconnect fitting and a valve located between the first end and the second end, said valve actuated by a lever attached to a shaft that penetrates through the walls of the cylinder, wherein said valve controls flow of water through the adapter such that when the valve is in a closed position no water can flow through the adapter, c) a circumferential ridge located on the adapter between the valve and the second end of the adapter, d) a coupler for attaching to a water supply input on the fire engine, said coupler comprising a cylinder having a fitting at a first end of said coupler for attaching to the fire engine water supply input and a fitting at a second end with a size and form for mating with the quick disconnect fitting on the adapter, e) said coupler including at least two lever actuators, said actuators operating a latching mechanism such that when the adapter is inserted into the coupler and the actuators are actuated to a locked position, the coupler and adapter are held together forming a water tight seal, f) said coupler further including at least one spring-loaded safety lever, said safety lever comprising: a first end and a second end and attached to a fulcrum incorporated in the coupler between the first end and the second end, the second end of the safety lever extending beyond the second end of the coupler, a spring located between the first end and the body of the coupler, such that pressing on the first end of the safety lever compresses the spring and lifts the second end of the safety lever, the second end of the safety lever comprising a hook that, when the coupler and the adapter are fit together, can engage the circumferential ridge located on the adapter and thereby prevent the adapter and coupler from being separated until both the at least two actuator levers are actuated to an unlocked position and the first end of the safety lever is pressed, g) whereby the fire hose may be connected to the hydrant and the hose charged with water by turning a valve on the hydrant with the valve on the adapter in a closed position and the adapter may be coupled and uncoupled from the fire hose while the fire hose remains charged with water.
