Abstract
Abstract An electrically heated window including an insulated corner gusset having an electrical lead extending therethrough to supply electrical power to one sheet of a plurality of parallelyarranged sheets of glass, one of which has been coated with an electroconductive transparent coating, and from which the supply of electrical power is removed upon a breakage of the glass sheet having the electroconductive coating, thus avoiding the possibility of an individual being subjected to an electrical shock by coming into contact with the broken glass.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
126 words
An electrically heated window unit comprising spaced apart glass panels, spacer means extending along the edges of said panels and secured thereto, the internal face of one of said panels having an electroconductive transparent coating thereon, spaced apart bus bars in contact with said coating, corner gussets between the said spaced apart said panels carrying leads for conducting electrical current from a source of electrical energy to the said bus bars, an electrical circuit including a circuit breaker having an electrical current flow responsive electronic device and a starting push button electrically shunting and adjusting said electronic device, said electronic device shutting off the supply of electrical power to said bus bars and electroconductive coating upon the breakage of the panel having the said coating thereon.
Claim 2
Dependent Claim
126 words
An electrically heated window unit comprising spaced apart glass panels, spacer means extending along the edges of said panels and secured thereto, the internal face of one of said panels having an electroconductive transparent coating thereon, spaced apart bus bars in contact with said coating, corner gussets between the said spaced apart said panels carrying leads for conducting electrical current from a source of electrical energy to the said bus bars, an electrical circuit including a circuit breaker having an electrical current flow responsive electronic device and a starting push button electrically shunting and adjusting said electronic device, said electronic device shutting off the supply of electrical power to said bus bars and electroconductive coating upon the breakage of the panel having the said coating thereon.
Claim 3
Dependent Claim
13 words
The structure recited in claim 1 wherein said gusset comprises an insulating block.
Claim 4
Dependent Claim
28 words
The structure recited in claim 1 wherein said circuit breaker includes a visual signal to indicate when the electric power source to said coated pane is shut off.
Claim 5
Dependent Claim
31 words
The structure recited in claim 1 wherein said circuit breaker includes an adjustable potentiometer to adjust the circuit breaker to the resistance of the electroconductive coating on the said coated pane.
Claim 6
Dependent Claim
26 words
The structure recited in claim 1 wherein said corner gusset is mitered to receive like mitered ends of a spacer extending between the said spaced panes.
