Claim 2

In apparatus for producing electrically heated automotive windows that comprise a sheet of glass with a conducting gridwork on a surface thereof including an electrode extending along one margin and a flexible bus bar soldered to said electrode and having a connecting pigtail extending loosely from one end, the improvement in means for soldering said bus bar to said electrode comprising means for supporting said bus bar and engageable with said sheet to locate and retain said bus bar in soldering relation to said electrode, said supporting means being generally U-shaped in transverse cross-section to permit the same to slide over an edge of said sheet and into engagement with adjacent margins on opposite surfaces thereof, a channel in one leg of said supporting means for retaining said bus bar between said leg and said sheet, a series of openings in the channel to expose said bus bar at predetermined points along its length for simultaneous soldering engagement with a plurality of soldering irons, and at least two generally U-shaped clamping members mounted in surrounding relation to said supporting means to resiliently urge the same into contact with the marginal portions of the glass sheet.

Claim 3

Apparatus as defined in claim 1, in which said supporting means includes means for supporting said pigtail in substantially parallel relation to said bus bar while separating it from said bus bar and from said sheet.

Claim 4

In apparatus for producing electrically heated automotive windows that comprise a sheet of glass with a conducting gridwork on a surface thereof including an electrode extending along one margin and a flexible bus bar soldered to said electrode and having a connecting pigtail extending loosely from one end, the improvement in means for soldering said bus bar to said electrode comprising means for supporting said bus bar and engageable with said sheet to locate and retain said bus bar in soldering relation to said electrode, said supporting means being generally J-shaped in transverse cross-section to permit the same slide over an edge of said sheet and into engagement with adjacent margins on opposite surfaces thereof, an inwardly opening channel in the longer leg of said supporting means for retaining said bus bar between said leg and said sheet, a series of openings in the channel to expose said bus bar at predetermined points along its length for simultaneous soldering engagement with a plurality of soldering irons, a plurality of clips formed in the surface of said longer leg for supporting said pigtail substantially parallel with but in spaced relation to said bus bar, and at least two channel shaped clamping members mounted in surrounding relation to said supporting means to resiliently urge the same into contact with the marginal portions of the glass sheet.

Claim 5

In apparatus for producing electrically heated automotive windows that comprise a sheet of glass with a conducting gridwork on a surface thereof including an electrode extending along one margin and a flexible bus bar soldered to said electrode and having a connecting pigtail extending loosely from one end, the improvement in means for soldering said bus bar to said electrode comprising means for supporting said bus bar and engageable with said sheet to locate and retain said bus bar in soldering relation to said electrode, said supporting means being generally J-shaped in transverse cross-section to permit the same slide over an edge of said sheet and into engagement with adjacent margins on opposite surfaces thereof, an inwardly opening channel in the longer leg of said supporting means for retaining said bus bar between said leg and said sheet, a series of openings in the channel to expose said bus bar at predetermined points along its length for simultaneous soldering engagement with a plurality of soldering irons, a plurality of clips formed in the surface of said longer leg for supporting said pigtail substantially parallel with but in spaced relation to said bus bar, and at least two channel shaped clamping members mounted in surrounding relation to said supporting means to resiliently urge the same into contact with the marginal portions of the glass sheet.
