Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
187 words
A hot liquid food dispenser comprising a housiNg and a discharge spout on the housing, a hot water tank within the housing including a heating element for heating water in said tank, a duct connected to the tank adjacent the top and to the spout for carrying water from the top of the tank to the discharge spout and a valve for controlling flow of water through the duct, a water reservoir on the housing which may be manually filled and located above the tank, means connected between the reservoir and the bottom of the tank for directing water from the reservoir to the bottom of the tank, said means including an auxiliary chamber and a transfer duct connecting the reservoir to the chamber, a passage connecting the chamber to the tank whereby water in the tank may flow into the chamber when the tank is full, and a second valve in said means for controlling flow from the reservoir to the tank and including a float disposed in said chamber causing the second valve to close when the water in the chamber reaches a selected level.
Claim 2
Dependent Claim
187 words
A hot liquid food dispenser comprising a housiNg and a discharge spout on the housing, a hot water tank within the housing including a heating element for heating water in said tank, a duct connected to the tank adjacent the top and to the spout for carrying water from the top of the tank to the discharge spout and a valve for controlling flow of water through the duct, a water reservoir on the housing which may be manually filled and located above the tank, means connected between the reservoir and the bottom of the tank for directing water from the reservoir to the bottom of the tank, said means including an auxiliary chamber and a transfer duct connecting the reservoir to the chamber, a passage connecting the chamber to the tank whereby water in the tank may flow into the chamber when the tank is full, and a second valve in said means for controlling flow from the reservoir to the tank and including a float disposed in said chamber causing the second valve to close when the water in the chamber reaches a selected level.
Claim 3
Dependent Claim
48 words
A hot liquid food dispenser as described in claim 1 further characterized by said auxiliary chamber being disposed immediately above the tank and said reservoir being positioned above the chamber whereby flow from the reservoir to the chamber and from the chamber to the tank is by gravity.
Claim 4
Dependent Claim
68 words
A hot liquid foot dispenser as described in claim 1 further characterized by said auxiliary chamber having two compartments, one of said compartments forming part of the means for carrying water from the reservoir to the tank and the other of said compartments being connected to the top of the tank by said passage and into which water may flow from the tank when the tank is full.
Claim 5
Dependent Claim
25 words
A hot liquid food dispenser as described in claim 1 further characterized by said reservoir having a removable cover and being vented to the atmosphere.
Claim 6
Dependent Claim
35 words
A hot liquid food dispenser as described in claim 4 further characterized by said reservoir being made of a material to enable an operator to observe the level of water therein without removing the cover.
Claim 7
Dependent Claim
47 words
A hot liquid food dispenser as described in claim 3 further characterized by said two compartments being in communication with one another within the chamber allowing water in said other compartment to flow into the first compartment when it reaches a selected level in the other compartment.
Claim 8
Dependent Claim
35 words
A hot liquid food dispenser as described in claim 6 further characterized by a vent tube disposed in said chamber and having an inlet above the selected level of the water in said other compartment.
Claim 9
Dependent Claim
52 words
A hot liquid food dispenser as described in claim 3 further characterized by said partition being a vertical cylindrical wall and dividing the chamber into the first compartment outside the partition and the other compartment inside the partition, and the communication between the compartments being over the top of the cylindrical wall.
Claim 10
Dependent Claim
36 words
A hot liquid food dispenser as described in claim 8 further characterized by said float being in the other compartment and closing the second valve when the water in said other compartment reaches a selected level.
Claim 11
Dependent Claim
28 words
A hot liquid food dispenser as described in claim 9 further characterized by said float carrying a baffle and directing water from the reservoir into the first compartment.
Claim 12
Dependent Claim
174 words
A hot liquid food dispenser comprising a housing and a discharge spout on the housing, a hot water tank within the housing including a heating element for heating water in said tank, a duct connected between the tank and spout for carrying hot water from the tank to the discharge spout, a water reservoir mounted above the tank and duct means connecting the reservoir and tank, said reservoir having means enabling it to be manually fitted while connected to the tank and being vented to the atmosphere, and a valve mounted in the duct means for controlling flow from the reservoir to the tank, said duct meaNs including an auxiliary chamber and a transfer duct connecting the reservoir to the chamber, a passage connecting the chamber to the tank whereby water in the tank may flow into the chamber when the tank is full, and said valve mounted in said duct means including a float disposed in the chamber causing the valve to close when the water in the chamber reaches a selected level.
Claim 13
Dependent Claim
174 words
A hot liquid food dispenser comprising a housing and a discharge spout on the housing, a hot water tank within the housing including a heating element for heating water in said tank, a duct connected between the tank and spout for carrying hot water from the tank to the discharge spout, a water reservoir mounted above the tank and duct means connecting the reservoir and tank, said reservoir having means enabling it to be manually fitted while connected to the tank and being vented to the atmosphere, and a valve mounted in the duct means for controlling flow from the reservoir to the tank, said duct meaNs including an auxiliary chamber and a transfer duct connecting the reservoir to the chamber, a passage connecting the chamber to the tank whereby water in the tank may flow into the chamber when the tank is full, and said valve mounted in said duct means including a float disposed in the chamber causing the valve to close when the water in the chamber reaches a selected level.
