adjacent sash stile, each parting stop section
having a groove formed in the side faceopposite
from the fulcrum forming rib and disposed Within
the channel inwardly from the rib, said groove
further opening at one side toward the bottom
of the channel, and a spring member secured
within the channel and engaged in the adjacent
