Abstract
Abstract A portable water purifying device is disclosed which includes a main housing provided with a main inner chamber to receive a purified water receptacle. An electric circuit provides a main "on-off" switch to provide a flow of water in its "on" position, from a suitable pressurized source through a purifying capsule into a suitable container such as a jug. When the container is full a limit switch shuts off the water flow and a signal light is illuminated. The container is removed and replaced with another empty container. In preferred form of the invention, a refill switch is provided to deenergize the signal light and to initiate another water purifying and container filling cycle.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
202 words
A water purifying device comprising a main housing providing a first inner chamber portion, a receptacle in said first chamber portion, and a second inner chamber portion and a water filtering cartridge in said second chamber portion, a water intake conduit connecting between a pressurized water source and a first end of said cartridge, a water feed conduit having a first end connected to a second end of said cartridge and a second end connecting to said receptacle in a manner whereby said receptacle will overflow after being filled, means to direct said overflow into a collector means, electric circuit means connected to a power source, including a main on-off switch and an overflow limit switch associated with said collector means; a first solenoid operated valve connected between said electric circuit means and intake conduit in a manner whereby said valve will be opened to direct a flow of water from said pressurized water source through said intake conduit and said cartridge into said receptacle when said on-off switch is in an on position, said overflow limit switch being responsive to a predetermined collection of water in said collector means to stop the flow of water through said cartridge into said receptacle.
Claim 2
Dependent Claim
202 words
A water purifying device comprising a main housing providing a first inner chamber portion, a receptacle in said first chamber portion, and a second inner chamber portion and a water filtering cartridge in said second chamber portion, a water intake conduit connecting between a pressurized water source and a first end of said cartridge, a water feed conduit having a first end connected to a second end of said cartridge and a second end connecting to said receptacle in a manner whereby said receptacle will overflow after being filled, means to direct said overflow into a collector means, electric circuit means connected to a power source, including a main on-off switch and an overflow limit switch associated with said collector means; a first solenoid operated valve connected between said electric circuit means and intake conduit in a manner whereby said valve will be opened to direct a flow of water from said pressurized water source through said intake conduit and said cartridge into said receptacle when said on-off switch is in an on position, said overflow limit switch being responsive to a predetermined collection of water in said collector means to stop the flow of water through said cartridge into said receptacle.
Claim 3
Dependent Claim
59 words
The device as defined in claim 1 including a first solenoid operated switch and a signal light connected in said electric circuit means in a manner whereby said solenoid operated switch will be actuated to energize said signal light to indicate a full condition of said receptacle when said predetermined amount of overflow has collected in said collector means.
Claim 4
Dependent Claim
77 words
The device as defined in claim 2 wherein said overflow limit switch is normally closed and comprises a weight operated switch including a removable cup, comprising said collector means carried on a switch arm thereof, and said means to direct said overflow includes a discharge tube opening into said cup, whereby the discharge of a predetermined amount of overflow water into said cup opens said overflow limit switch and stops the flow of water into said receptacle.
Claim 5
Dependent Claim
53 words
The device as defined in claim 1 including a two position relay in said electric circuit means, a first switch portion thereof being normally closed to complete a first circuit portion to open said first solenoid valve to fill said receptacle with water when said main on-off switch is in said on position.
Claim 6
Dependent Claim
101 words
The device as defined in claim 4 wherein said overflow limit switch is normally in an open position and including means to move said limit switch to a closed position in response to said predetermined collection of water in said collector means to simultaneously energize said relay to disengage said first switch portion thereof to stop said flow of water and to energize a second circuit portion through said relay, said second portion including a signal light to visually indicate said predetermined water collection in said collector means, and to engage a second switch portion to energize a third circuit portion.
Claim 7
Dependent Claim
74 words
The device as defined in claim 5 wherein said third circuit portion includes a manually controlled, normally open refill switch, a water pump extending into said collector means and a second solenoid valve connected between a drain means and said third circuit portion, whereby said second solenoid valve is opened and said water pump is energized to evacuate the water from said collector means through said drain means when said refill switch is closed.
Claim 8
Dependent Claim
61 words
The device as defined in claim 6 wherein said collector means comprises a housing with an inner chamber to collect said overflow water, and a float in said chamber, comprising said means to move, attached to said limit switch which is electrically connected to said water pump to energize same when the water rises to a predetermined level in said chamber.
Claim 9
Dependent Claim
49 words
The device as defined in claim 7 including a main drain conduit connecting from said cartridge second end for extension to a remote disposal area, and a manually controlled shut-off valve, interposed in said main drain conduit, including hand grip means for selective opening and closing of said valve.
Claim 10
Dependent Claim
51 words
The device as defined in claim 1 wherein said water feed conduit terminates at said second end in a cap having an inner diameter, said inner diameter being enlarged relative to an outside diameter of a top end open neck of said receptacle, said cap being disposed over said open neck.
Claim 11
Dependent Claim
73 words
The device as defined in claim 1 wherein said means to direct comprises a pan including peripheral upstanding side walls, disposed beneath said receptacle in a manner so as to catch said overflow, a support means for said pan, angled in a manner as to position one corner portion of said pan at a lower level than the balance thereof, and a drain tube communicating between said lower corner and said collector means.
Claim 12
Dependent Claim
17 words
The device as defined in claim 1 including a strainer fitting interposed in said water feed conduit.
