27 in the opposite direction it is seen that both
sashes will be closed to the position shown in
containing window glass 1.
Hollow channel members 8 and 5 longitudinal

nested and-suitably secured against the vertical
members of frame I, with said slotted portions
facing the outside of the frame.

the two bevel gears 25‘ and'ZI keyed on opposite
ends of horizontal shaft 22 which is rotatably
supported by the two brackets 23 and 24 depend
ing below sill 2.
'
_
As'shown in Figs. 1 and 2 brackets 25- and 25
depending-centrally below sill 2 provide a journal
and support for the manually rotatable window
regulator 27 with shaft 28. Worm gear 29 keyed
on shaft 23 operatively and threadably meshes
3
Dogs 3| and 32 shown in Figs, 1 and 3 pivotally
hinged at 33 within notches 3:1 in the bottom of
sash 3 are in threaded engagement at 35 and
36 with‘the respective vertical rotatable shafts
II and I2 and their threaded portions I3 and I4.
On the other hand dogs 31‘ and 38 shown in
Figs. 1, '2 and 5 pivotally hinged at 39 at the top
edge of upper sash 6 have laterally ?anged guide
portions 45 on the ends thereof for cooperative
sliding engagement against the inner surface of
channel members 8 and 9 within frame I.
Guides 40 are normallyretained slightly be
lowtheir extreme upper position by the ~trans~
verse pins 4i slida-ble through frame I and chan
nel members 8 and 5. Pins 4| with handles 42
have annular collars £53 engaged by coiled springs
44 within spring housings 45 which springtends
to resist withdrawing of said pins partiallyfrom
frame I but allows suf?cient withdrawal to per
mit dogs 3'! and 38 to be free to drop within
channel members 8 and 9.
-
Thus a sliding pivotal support is provided for
the upper part of sash 5, which is adapted for
guided sliding vertical adjustment through dogs
3‘! and 38 within slotted channels 8 and 9; With
the amount of friction previously ascertained be
tion, with upper sash 6 horizontally resting
‘ thereon and also riding downwardly.
Thus both
sashes may be brought down while remaining in
horizontal parallel relation to the sill 2 near the
bottom of frame I. In this position the outside
surface of glass ‘I of upper sash 6 may be easily
washed. While in the extreme upward horizon~
tal positions or intermediate horizontal positions
of sashes 3 and E the outside of glass 4 in the
lower sash can be easily washed.
It is contemplated that lower dog attachments
35 and 36 may have projections 35’ as in Fig. 2
for operative engagement with the ends of pins
Ill angularly shaped at M’, for causing releas
with gear 3i] keyed on horizontal shaftv 22, where- i
by rotation of regulator 2? will cause rotation of
shaft 22 and rotation of shafts'II and i 2 geared
thereto.
.
However at elevated horizontal position of both
sashes at the top of frame I, pins III may be
manually withdrawn sufficiently against springs
.
As shown in Figs. 1 through 4 shafts II and I2

endsof vertical shafts II and I2 are rotatably

ing movement to the right on engagement there
with, at the same time permitting release of
upper dog guides 40, permitting downward move
ment thereof.
Without actuation of handle ‘21 upper sash 6
may be lowered merely by manually releasing
pins 4! permitting dogs 3'! and 38 toguidingly
slide downwardly to any intermediate position
along window frame I. It is seen that any down
ward movement of sash 5 causes at least out
ward movement of the hinged portion 5 of the
two sashes, even though'the lower portion of the
lower sash remains stationary.
Weatherstripping 46 and 4'! is provided upon
the'bottom edges respectively of sashes 6 and 3,
and are so provided that a slight releasing move
ment of handle 21 will permit the central hinged
portion 5 to snap outwardly suf?ciently to ‘pre
vent any binding of the sashes against each other
upon further actuation of handle 21. By this
“pop out’? action it is clear that any of the ad~
justments of the sashes above described are pos
sible without any binding. I
In fully closed position of the window as, in
50 Fig. 2,‘ upper sash‘ 3 rests upon lower sash 3.
However in the initial “pop out” position above,
upper dog members 33 and 39 drop down slightly
to rest upon pins 4|. '
’ While the above description shows means re
leasing the upper sash to be free falling subject
to a certain amount of desired sliding friction,
it is contemplated that dogs 37 and 38 may be in
threaded engagement with corresponding thread- I
ed portions oppositely‘ threaded in direction from
tween ?anged portions 40 of dogs 37 and 33 and
slotted channels 8 and 9 it is possible to effect , (SO threaded portions I3 and I4, as shown in Fig. '7.
