The gas fill device for multiple pane windows includes a tube installed through the peripheral spacer bar between two glass panes in an insulated glass assembly for a window, door glass, skylight, or the like. An elbow is pivotally attached to the external end of the tube. A supply of an inert, insulating gas may be attached to the elbow to refill the space between the two panes with the insulating gas, as needed. Two such tubes may be installed in each multiple pane window assembly, one to refill the space with insulating gas and the other to vent air from the space to the atmosphere as the space is refilled with the insulating gas. When the multiple pane window has more than two panes, the tube may be branched and supplied through a common elbow.

1. A gas fill device for a multiple pane window, comprising: at least one gas fill tube adapted for permanent installation through a spacer bar separating the multiple panes, the gas fill tube having a first end communicating with an insulating volume of gas disposed between the multiple panes and having a second end opposite the first end, the second end being disposed external to the insulating volume of gas and includes a radial, annular groove;a hollow elbow pivotally attached to the second end of the at least one gas fill tube, the elbow having a first end communicating with the second end of the gas fill tube and a second end opposite the first end, wherein the first end defines an inwardly disposed annular flange sized and configured to pivotally mate with the radial groove of the second end of the gas fill tube; anda closure removably sealed to the second end of the elbow. 2. The gas fill device for multiple pane windows according to claim 1, wherein the tube has a bifurcated first end defining a first branch and a second branch, the first branch and second branch being joined adjacent the second end. 3. The gas fill device for multiple pane windows according to claim 1, wherein the closure is selected from the group consisting of threaded caps and snap-on caps. 4. The gas fill device for multiple pane windows according to claim 1, further comprising a multiple pane window having: at least one peripheral spacer bar, the spacer bar having mutually opposed first and second pane sealing surfaces;a first window pane sealed to the first pane sealing surface; anda second window pane sealed to the second pane sealing surface, the spacer bar and the panes defining an insulating volume therebetween. 5. The gas fill device for multiple pane windows according to claim 4, wherein: the spacer bar has a lower portion and an upper portion;the gas fill tube with the attached elbow and the attached closure is installed in the lower portion of the spacer bar; andthe multiple pane window further includes a vent tube, a vent elbow connected to the vent tube, and a vent cap assembly attached to the vent elbow to form a vent assembly, the vent assembly being installed in the upper portion of the spacer bar. 6. The gas fill device for multiple pane windows according to claim 4, further including at least one humidity indicator disposed within the insulating volume of the window. 7. The gas fill device for multiple pane windows according to claim 1, further comprising a multiple pane window having: a first spacer bar;a first pane and a second pane sealed to the spacer bar, capturing the first spacer bar therebetween and defining a first insulating volume;a second spacer bar, sealed to the second pane; anda third pane sealed to the second spacer bar, capturing the second spacer bar between the second pane and the third pane and defining a second insulating volume. 8. The gas fill device for multiple pane windows according to claim 7, wherein said hollow tube has a bifurcated first end defining a first branch and a second branch, the first branch extending through the first spacer bar and the second branch extending through the second spacer bar, the first branch and the second branch being joined together external to the first and second insulating volumes. 9. A double-pane window, comprising: a first window pane;a second window pane equal in size to the first window pane, the second window pane being disposed parallel to the first window pane;at least one spacer bar extending around the first and second window panes, the first and second window panes being sealed to the at least one spacer bar to define an enclosed space between the window panes;an inert gas having thermal insulation properties disposed in the enclosed space;a gas delivery tube extending through the spacer bar and communicating with the enclosed space, the gas delivery tube having a first end communicating with the inert gas and having a second end opposite the first end, the second end being disposed external to the inert gas and includes a radial, annular groove;an elbow pivotally attached to the gas delivery tube external to the spacer bar, the elbow having a first end communicating with the second end of the gas delivery tube and a second end opposite the first end, wherein the first end defines an inwardly disposed annular flange sized and configured to pivotally mate with the radial groove of the second end of the gas delivery tube; anda cap releasably attached to the elbow, the elbow being adapted for connection to a supply of the thermal insulation gas when the cap is removed in order to refill the enclosed space with the gas when needed. 10. The double-pane window according to claim 9, wherein said cap comprises a threaded cap, the elbow having corresponding threads. 11. The double-pane window according to claim 9, wherein said cap comprises a snap-on cap. 12. The double-pane window according to claim 9, further comprising a vent tube extending through said at least one spacer bar, the vent tube communicating with the enclosed space, the vent tube having a removable cap. 13. The double-pane window according to claim 9, further comprising at least one humidity indicator disposed within the enclosed space.
