When the top window 30 is in a normally closed
position it abuts against stop strips 8 which limit
its outward movements as before indicated. Stop
strips 8 are sufficiently laterally oñîset with re
spect to stop strips 1 so as to allow independent
vertical adjustments of both upper sash 3U and
lower sash 3l in side by side relationship. When
both upper sash 30 and lower sash 3| are in their
normally closed position the upper cross member
33 of lower sash 3|, and the lower cross member
311 of upper sash 30 are in substantially the same
horizontal plane and may be locked together by
a conventional rotary cam locking device which
consists of a rotary cam member 4B on the cross
