Attendant propelled portable spraying apparatus

A wheeled, walking attendant propelled spraying apparatus, comprising:

• a cart comprising a frame and wheels connected to a lower portion of the frame, a spray hose storage reel adapted to receive a length of hose thereon, means journaling said reel onto said frame for rotation during wrapping and unwrapping of the spray hose, a swivel coupling including an outlet rotatable with the spray hose storage reel which is connectible to the spray hose and a non-rotating inlet located at one end of said spray hose storage reel, said frame including a forward projecting shelf generally below the reel, and a handle above the spray hose storage reel;
• a storage tank for a liquid to be sprayed, mounted onto said shelf generally below the hose storage reel;
• apparatus for removing a liquid from said tank and delivering it in diluted form into the inlet of said swivel coupling, comprising an inlet fitting connectible to a water hose and a jet pump connected in series and mounted onto said cart frame, said jet pump having a pumping fluid passageway
• in water receiving communication with said inlet fitting, a pumped fluid inlet and a combined fluid outlet, a first conduit interconnected between the combined fluid outlet of said jet pump and the inlet of said swivel coupling, and a second conduit interconnected between the storage tank and the pumped fluid inlet of said jet pump, said second conduit including flexible hose means and adjustable metering means to regulate the rate of removal of liquid from the storage tank;
• and wherein a first check valve is provided in series with and between the inlet fitting and the jet pump, for preventing back flow through the jet pump into the water supply, and wherein a second check valve is provided in the second conduit, to prevent back flow from the jet pump into the second conduit;
• whereby the cart can be wheeled into a yard, a hose can be connected between a water faucet and the inlet fitting, and the spray hose can be unwrapped from the reel and used by an operator to spray a water diluted liquid without the encumbrance of a mixing apparatus at the outlet end of the spray hose.
