Abstract
Abstract A vending machine such as a coffee vending machine has a hot water tank connected to the outlet side of a pump. The inlet side of the pump is selectively connected to one of a plurality of water storage containers by way of a valve. Water for the hot water tank is pumped thereto from the storage containers. When a storage container is empty, the valve is moved to a position so as to communicate with another one of the containers.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
180 words
An improvement in a vending machine with a self-contained water supply comprising a vending machine having a water tank from which water is to be dispensed, a pump having its outlet connected to said tank, said tank having a means for controlling operation of said pump in response to the level of water in said tank so that the pump is operative when the water level in said tank is below a predetermined level, a plurality of water storage containers, a valve having a plurality of inlets and a single outlet, said valve outlet being connected to the inlet side of said pump, each valve inlet being connected to one of said storage containers, said valve including a valve member for selectively controlling flow from said inlets to said valve outlet, a motor connected to said valve member, circuitry interconnecting said valve motor and said pump with said liquid level responsive means so that when water in one storage container is depleted, the valve member is moved by said motor to communicate said pump inlet with another of said containers.
Claim 2
Dependent Claim
180 words

Claim 3
Dependent Claim
30 words
Apparatus in accordance with claim 1 wherein said circuitry includes a delay means for delaying actuation of the valve member by its motor subsequent to initiating operation of said pump.
Claim 4
Dependent Claim
44 words
Apparatus in accordance with claim 1 wherein said valve member is a rotary valve member, said motor being coupled to said valve member to rotate said valve member about its longitudinal axis until the motor is rendered inoperative by said liquid level responsive means.
Claim 5
Dependent Claim
40 words
Apparatus in accordance with claim 1 including a common support for said pump, valve and valve motor, said pump being connected to the upper end of said valve and said motor being connected to the lower end of said valve.
Claim 6
Dependent Claim
25 words
Apparatus in accordance with claim 1 wherein said circuitry includes a manually operable pushbutton for initiating operation of said pump to initially fill said tank.
Claim 7
Dependent Claim
39 words
Apparatus in accordance with claim 1 wherein said circuitry includes means for rendering said pump and motor inoperative unless said tank is filled within a predetermined number of seconds subsequent to the initiation of the operation of said pump.
Claim 8
Dependent Claim
30 words
Apparatus in accordance with claim 1 wherein said valve has four inlets each on a different side face thereof with said outlet being on an end face of the valve.
