ABSTRACT:
A braking system for a reel for a hose used to dispense fluids. The reel end of the hose is provided with a fluid connection on the reel itself and a supply line for the fluid is connected into the reel such that a flow can be established through the hose even though hose is still wound on the reel. A brake with actuating means is provided for the reel. Various types of brakes such as a caliper-disc type, a band and drum type, or a double-shoe type can be used. Brake actuation is by means of a pressurized hydraulic or pneumatic fluid or by an electrically operated solenoid. A flow sensor is incorporated in the fluid supply line to the hose and the output of the sensor is used to enable the brake actuator to brake the reel. In this system, when the flow sensor detects a flow through the hose, the sensor produces an output signal which is used to cause the actuation of the reel brake. In operation, to apply the reel brake such as to stop the unwinding of the hose when it is being pulled from the reel, the hoseman merely opens the valve in the hose nozzle to initiate a flow through the hose and the brake is applied automatically.
