Abstract
Abstract An automatic fluid-dispensing apparatus for measuring and dispensing preselected quantities of fluids. Upon selection of the desired dispensing quantity the apparatus is triggered and automatically fills the container with substantially the exact required amount of fluid thus substantially eliminating overpouring of the fluid to reduce loss through spillage. The quantity of fluid dispensed is accurately counted whereby an inventory of the fluid may be maintained at all times. Where the fluid is a gas-charged liquid, a foam control means is provided.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
123 words
A gas-charged liquid dispensing device comprising a head including a dispensing nozzle, valve means leading to the head and communicating with the nozzle and movable from a closed position to an open position to interrupt or permit flow of fluid to the nozzle, said dispensing nozzle including an elongated tube discharging directly to a receiver, a body member constituting a foam-controlling means disposed within said tube, and having a smaller stem and a longitudinally extending enlarged portion thereon, said enlarged portion having smooth gradually changing flow-conducting surfaces at each end thereof, and said enlarged portion being spaced from the outer end of said tube whereby a liquid of the desired quality of foam is produced as the gasiFied liquid passes said enlarged portion.
Claim 2
Dependent Claim
123 words
A gas-charged liquid dispensing device comprising a head including a dispensing nozzle, valve means leading to the head and communicating with the nozzle and movable from a closed position to an open position to interrupt or permit flow of fluid to the nozzle, said dispensing nozzle including an elongated tube discharging directly to a receiver, a body member constituting a foam-controlling means disposed within said tube, and having a smaller stem and a longitudinally extending enlarged portion thereon, said enlarged portion having smooth gradually changing flow-conducting surfaces at each end thereof, and said enlarged portion being spaced from the outer end of said tube whereby a liquid of the desired quality of foam is produced as the gasiFied liquid passes said enlarged portion.
Claim 3
Dependent Claim
26 words
A gas-charged liquid-dispensing device as set forth in claim 1 wherein said valve means is quick opening to fully open and quick closing to fully closed.
Claim 4
Dependent Claim
26 words
A gas-charged liquid-dispensing device as set forth in claim 2 wherein said valve means is disposed adjacent the source of said gas charged liquid under pressure.
Claim 5
Dependent Claim
24 words
A gas-charged liquid-dispensing device as set forth in claim 1 and including a solenoid actuated operator for opening and closing of said valve means.
Claim 6
Dependent Claim
62 words
A gas-charged liquid-dispensing device as set forth in claim 1 and including actuating means operably connected with said valve for opening and closing thereof, timing means operably connected with said actuating means for controlling the opening of said valve means to provide for flow of a predetermined quantity of the liquid to the dispensing nozzle during the open position of the valve.
Claim 7
Dependent Claim
36 words
A gas-charged liquid-dispensing device as set forth in claim 5 and including selector switch means operably connected with said timing means for selective actuation thereof to deliver said predetermined quantities of liquid to the dispensing nozzle.
Claim 8
Dependent Claim
48 words
A gas-charged liquid-dispensing device as set forth in claim 6 wherein said selector switch means comprises a plurality of independent selector switches operably connected to provide variable timing operation of the valve means whereby a variety of preselected quantities of the liquid are independently dispensed through the nozzle.
Claim 9
Dependent Claim
38 words
A gas-charged liquid-dispensing device as set forth in claim 5 and including counting means operably connected with the timing means and operable upon opening of the valve for recording the quantity of liquid dispensed by the dispensing device.
Claim 10
Dependent Claim
22 words
A gas-charged liquid-dispensing device as set forth in claim 1 wherein said stem and body member is adjustably secured within said tube.
