Abstract
Abstract A support member for connecting panels of a curtain wall to horizontal mullions. Each mullion has a channel formed therein and has shoulders at opposite sides of the channel. The panel support member comprises a rigid bar, positioned in the channel in the mullion, and a tenon extending longitudinally of the bar. Anchor lugs extend outwardly from opposite sides of the tenon. A gasket, having panel receiving slots formed therein, has a groove extending longitudinally thereof to receive the tenon and anchor lugs. As anchor bolts are tightened, drawing the bar into the channel in the mullion, external abutments on the gasket are drawn into the channel such that a portion of the gasket is captured between the shoulders and the lugs to resist deformation of the gasket relative to the load carrying tenon.

Claim 1
Independent Claim
209 words
Apparatus to secure a curtain wall to a structural frame including: a horizontal mullion, said horizontal mullion having a channel formed therein; upper and lower shoulders formed horizontally along opposite sides of said channel; an elongated gasket support bar; a support tenon extending longitudinally of said support bar; anchor lugs extending longitudinally of the tenon on opposite sides thereof; an elongated resilient gasket, said gasket having a groove formed longitudinally in the inner face of said gasket of such shape and dimension as to receive said tenon and anchor lugs, said tenon and anchor lugs being disposed in and extending longitudinally of said groove, said anchor lugs being positioned adjacent said upper and lower shoulders, said gasket having upper and lower panel-receiving slots formed along opposite faces thereon, the upper slot being positioned above said tenon such that the tenon supports a panel disposed in the slot above the gasket, said gasket having abutment faces formed longitudinally of the gasket extending outwardly of the inner face of the gasket; and means to draw said support bar and abutment surfaces into said channel between said upper and lower shoulders to restrain said gasket about said tenon and anchor lugs and secure said support bar and gasket to said horizontal mullion.
