Before forming up this mullion the holesshould be punched in the sides to admit the pivot II S. These mullionsare shown in position in Fig. 168 by E E, etc. F G in Fig. 183 represents the section of the side of the sash belowthe pivot T. Notice that this lower half of the side of the sash has alock attachment which hooks into the flange of the mullion E at F.^^^lile the side of the sash is bent in one piece, the upper half, above thepivot T, has the lock omitted as shown by J K.

This cap isfastened to the Upper part of the mullion E with a projecting hood /which is placed at the same angle as the sash will have when it isopened as shown by e e and d d! or by the dotted lines.
