applicable directly to the window sash, it is
obvious that such attachments may also be used
by connecting one to the top member of the
window frame (not shown) and another to the
window frame sill (not shown). As a matter
of fact, I contemplate using the invention even
between the meeting rails of upper and lower
sliding sashes. Primarily, however, I am in

By way of summation, it is to be pointed out
that the principal novelty in‘ the invention at
hand is predicated on a metal weather strip
V-shaped form embodying a relatively narrow
attaching and anchoring ?ange adapted to be
secured to an edge of one of the vertical rails
of a sash frame and a correspondingly elongated
but wider resilient ?ange opposed to the attach~
