ABSTRACT:
An adjustable window construction is disclosed wherein improved sash carriers prevent damage to any of the components of the window assembly when the sash is forcibly raised to its uppermost position, or when the sash is disengaged from the upwardly biased sash carriers during removal of the sash. When a sash carrier reaches its uppermost position, the novel tapered upper end of the sash carrier gradually engages and wedges within the lower end of the spring cover located above it, slowing the sash carrier and dissipating much of its kinetic energy to reduce the force of final impact of the sash carrier with the spring cover.
