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
member 33 of lower sash 3| and a ñxed lock

works axially through said housing 31 and has
its inner end 39 projecting through an opening

operator pulls outwardly on the handle 39 of the
plunger pin 38 so as to remove the inner end 45
from the openings 29 of the arm I9. The window
may then be moved to the desired vertical posi

movement.
The degree of braking or clutching action,
which is desired to be applied to the pivotal move

by varying the adjustment of tensioning nuts
