Abstract
Abstract A predetermined quantity of hot liquid is supplied from a delivery reservoir to a whipper chamber to which a measured quantity of powder such as powdered chocolate is supplied by a motor driven auger. Whipping action is effected in the shipper chamber by means of a motor driven impeller and the mixed product is dispensed through a dispensing outlet into a receptacle therebelow. The receptacle is effective when placed below the dispensing outlet to initiate the operation by engagement with a pivotally mounted control bracket which when moved initiates a control action and the resultant aforementioned operation. Hot liquid in the delivery reservoir is supplied thereto by a motor driven pump controlled by the control system from a supply reservoir in which hot liquid is maintained at all times. Flow of hot liquid from the delivery reservoir into the whipper chamber is controlled by a solenoid control valve, the action of which is predetermined by a motor driven timing means.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
157 words
A liquid supply system comprising a delivery reservoir having a supply inlet, a supply outlet, and a level control outlet, a supply reservoir interconnected with said level control outlet through a return conduit and with said supply inlet through a supply conduit in series with a pump, and control means for controlling operation of said pump whereby liquid is drawn from said supply reservoir through said supply conduit to said delivery reservoir by said pump and whereby the level of liquid in said delivery reservoir is maintained substantially constant at a level determined by said level control outlet, the rate of flow of liquid into said delivery reservoir being at least as great as the rate of flow out of said delivery reservoir through said supply outlet and operation of said pump being initiated before the opening of said valve and operation of said pump being stopped after closing of said valve during a liquid dispensing cycle.
Claim 2
Dependent Claim
157 words
A liquid supply system comprising a delivery reservoir having a supply inlet, a supply outlet, and a level control outlet, a supply reservoir interconnected with said level control outlet through a return conduit and with said supply inlet through a supply conduit in series with a pump, and control means for controlling operation of said pump whereby liquid is drawn from said supply reservoir through said supply conduit to said delivery reservoir by said pump and whereby the level of liquid in said delivery reservoir is maintained substantially constant at a level determined by said level control outlet, the rate of flow of liquid into said delivery reservoir being at least as great as the rate of flow out of said delivery reservoir through said supply outlet and operation of said pump being initiated before the opening of said valve and operation of said pump being stopped after closing of said valve during a liquid dispensing cycle.
Claim 3
Dependent Claim
184 words
A liquid supply system comprising a delivery reservoir having a supply inlet, a supply outlet, and a level control outlet, a supply reservoir interconnected with said level control outlet through a return conduit and with said supply inlet through a supply conduit in series with a pump, control means for controlling operation of said pump whereby liquid is drawn from said supply reservoir through said supply conduit to said delivery reservoir by said pump and whereby the level of liquid in said delivery reservoir is maintained substantially constant at a level determined by said level control outlet, the rate of flow of liquid into said delivery reservoir being at least as great as the rate of flow out of said delivery reservoir through said supply outlet, and temperature responsive means arranged to respond to the temperature of liquid in said delivery reservoir to actuate said pump when such temperature drops to a predetermined level and to shut off said pump when such temperature rises to a predetermined level, said temperature responsive means being ineffective to shut off said pump during a liquid dispensing operation.
Claim 4
Dependent Claim
184 words
