       3 . The installation bracket for the erection of a curtain wall in accordance with  claim 1  wherein said horizontal support member and said vertical support member are I-beam shaped defining two opposing C-shaped longitudinal channels, like facing channels on said horizontal support member and said vertical support member accommodating a section of a nose protruding member of a secured vertical mullion and a section of a nose protruding member of a horizontal mullion having one end of which secured to said vertical mullion, said vertical support member of said installation bracket secured over said nose protruding member of said vertical mullion and said horizontal support member of said installation bracket secured over said nose protruding member of said horizontal mullion thereby providing support for said horizontal mullion while a second end of said horizontal mullion is being secured to an adjacent vertical mullion.  
   
   
       4 . The installation bracket for the erection of a curtain wall in accordance with  claim 3  wherein said installation bracket is reversible.  
   
   
       5 . The installation bracket in accordance with  claim 1  wherein said vertical support member and said horizontal support member are further secured by means of an angled support arm secured angularly between said horizontal and vertical support member.  
   
   
       6 . The installation bracket in accordance with  claim 1  wherein said horizontal support member, said vertical support member, and said angled support member are fabricated from extruded aluminum.  
   
   
       7 . An installation bracket for the erection of a curtain wall wherein the curtain wall is comprised of a plurality of intersecting vertical and horizontal mullions, the vertical and horizontal mullions being formed with a longitudinally protruding nose portion on one longitudinal face, which protruding nose portions defines a spacial area for receipt of a window panel or the like after the curtain wall is fully erected, the installation bracket comprising: 
 a horizontal support member and a vertical support member secured in 90 degree relationship, said horizontal support member and said vertical support member being I-beam shaped in cross section and defining longitudinal slots accommodating a nose protruding portion of a secured vertical mullion and a nose protruding portion of a horizontal mullion having one end of which secured to said vertical mullion, said vertical support member of said installation bracket secured over said nose protruding portion of said vertical mullion and said horizontal support member of said installation bracket secured over said nose protruding portion of said horizontal mullion thereby providing support for said vertical mullion while a second end of said horizontal mullion is being secured to an adjacent vertical mullion.    
   
   
       8 . The installation bracket in accordance with  claim 7  wherein said vertical support member and said horizontal support member are further secured by means of an angled support arm secured angularly between said horizontal and vertical support member.  
   
   
       9 . The installation bracket in accordance with  claim 7  wherein said horizontal support member, said vertical support member, and said angled support member are fabricated from extruded aluminum.  
   
   
       10 . An installation bracket for the erection of a curtain wall wherein the curtain wall is comprised of a plurality of intersecting vertical and horizontal mullions, which define a spacial area for receipt of a window panel or the like after the curtain wall is fully erected, the installation bracket comprising: 
 a horizontal support member and a vertical support member are of I-beam shaped construction defining two opposing C-shaped longitudinal channels, said horizontal support member and said vertical support member secured in 90 degree relationship, said vertical support member having selectively securable thereto, an extender plate in a vertical plane;    said C-shaped longitudinal channels of said horizontal support member and vertical support member engageable with a nose protruding member of a horizontal mullion and a vertical mullion when said mullions are formed with said nose protruding member for support of said horizontal mullion;    said extender plate of said vertical mullion in abutting clamped relationship with said outer surface of said vertical mullion when said vertical mullion has no nose protruding member and said C-shaped channel of said horizontal support member engages a nose protruding member of said horizontal mullion for support of said horizontal mullion while a second end of said horizontal mullion is secured to an adjacent vertical mullion.
