Application September 10, 1936, Serial No. 100,099
5 Claims.
(Cl. 189-75)
The present invention relates to an improve
ment in curtain box structure for car windows,
particularly railway cars, busses, or the like, in
which the window curtain is enclosed in a box
forming a permanent built-in part of the car
5
structure. In certain structures heretofore in
2, and showing the relation of the parts during
insertion or removal of the window sash.
Similar reference characters indicate corre
sponding parts throughout the several ?gures
the curtain box in order to enable the upper rail
of the sash to be engaged or disengaged with
of the drawing.
Referring to the drawing, in which one end
only of the structure is illustrated, the other
end being identical, the window structure com
prises side posts ID, a top cross bar it of L
shape in cross-section arranged to be engaged by
the upper end of the window frame. It is an ob
the outer side of the top rail of the window
ject of the present invention to provide a curtain
sash, and a sill I2, the side posts being secured
use it has been necessary in order to remove or
install the window sash to remove or dismantle
box structure which may be a permanent built-in
part of the car structure and which will at the
Li same time permit removal and installation of the
window sash, without necessity for removing the
curtain box, and to this end it is particularly
proposed, in the exemplary illustrated embodi
ment of the invention, to provide one wall of the
box in the form of a hinged flap which may be
adjusted during the removal or installation of the
sash to provide a su?lciently large opening at the
top of the window frame to enable the sash to be
inserted or removed at an angle.
Another object is to provide such hinged wall
normally pressed toward the sash by spring pres
sure, and having weather-stripping means which
will be automatically pressed into snug engage
ment with the upper end of the sash by spring
pressure thereby bringing about a Weatherstrip
ping seal between the top rail and curtain box.
With the above and other objects in view an
embodiment of the invention is shown in the
accompanying drawing and this embodiment will
C: Li be hereinafter more fully described with reference
thereto, and the invention will be ?nally pointed
out in the claims.
In the drawing:
Fig. l is a view partially in inside and partially
40 in vertical section, taken along the line A—-A of
Fig. 2, the curtain and curtain roll being re
moved for the sake of clearness.
Fig. 2 is a vertical sectional view, taken along
_ the line B—B of Fig. 1, the curtain and curtain
roll being in place.
Fig. 3 is a horizontal sectional View, taken along
the line C—C of Fig. 2.
Fig. 4 is a horizontal sectional view, taken along
the line D—-D of Fig. 2.
Fig. 5 is a horizontal sectional View similar to
Fig. 3, but with the sash removed, the curtain and
curtain roll being removed for the sake of clear
ness.
Fig. 6 is a vertical sectional view similar to Fig.
to the frame structure l3, of the car, and the bar
H being secured to the outer wall header struc
ture ill of the car.

The sash comprises a top rail l5, side strips it,
and a glass panel t7, the side strips being slidably
mounted for vertical movement in vertically dis
posed channel structures mounted upon the side
post it. These channel structures are of a type
which permits one side of the channel to be re
0
moved for the purpose of removing the sash
and each consists of an L-shaped strip l8 secured
at its base to the side post 10 and the frame
structure i3 by screws l9 and constituting the
25
outer leg of the channel, and a removable strip
20 having a recess 2| engaged upon a ?ange 22 of
the strip 88 and constituting the inner leg of
the channel.
Within the channel there is pro
vided a channel strip 23 resiliently pressed
against the edge of the sash by an elongated leaf
spring 2d of Z-shape in cross-section. This chan
nel structure having a removable side leg is of
the type, for example, as disclosed in the patent
to Thomas G. Conway, for Box or car window 03 5
construction, No. 2,012,156, dated August 20, 1935.
Upon each of the side posts it there is also
provided a vertically grooved curtain guide strip
25 secured to the post 50 and frame structure
l3 by screws 26.
The curtain box is mounted at the upper end
29 of the frame and comprises a top wall 2i, end
walls 28, a front wall 29, and a rear wall 30, the
latter terminating in upwardly spaced relation to
the lower ends of the side walls 28. The cur
tain 3| is mounted upon a roller 32 within the
box and its edges are guided in the grooves of
the guide strips.
A hinge rod 33 is supported between the ends 28
of the curtain box at a point slightly in front of 50
the rear wall 30 and above its lower edge. A
flap member 34 outwardly offset at its lower por
tion, as at 35, has a strip 36 secured thereon at
its inner side, the lower edge of the flap being
bent over upon the lower edge of the strip as
2.

at $7. The strip 36 is provided at its ends with
‘rugs 38 bent inwardly at right angles therefrom
upon which are secured ears 39 provided at the
lower ends of the forwardly bent quadrant-like
- end pieces 136 provided at the respective ends of
the flap 34, the upper edges of these end pieces
being inclined and each engaged beneath the rod
where it is hingedly retained in place by a
10
headed screw G! engaging a slot 42 in the end
piece, concentric to the axis of the rod 33, and
which screw is screwed into a nut ‘i3 secured to
the end 23 of the box.
Springs 44 are disposed
upon the rod 33 and have one end 45 bearing
upon the wall 3!.‘- of the box and the other end
15
bearing upon the ?ap 34. Upon the outer side
of the ?ap 36 there is secured a weather strip
6'! which is pressed into engagement with the
upper rail E 5 of the window sash by the pressure
of the spring
In the normal operation of the structure the
20
screws iii are loose, so that the ?ap may con
tinuously press toward the rail to thereby auto
matically retain the weather-stripping in tight
resilient engagement therewith. When it is de
25 sired to remove the window sash the flap is
pressed inwardly, as shown in Fig. 6, and is held
in tln's position by tightening the screws 4|.
Thereupon the side leg strips 20 of the side chan
nels are removed and the window sash may be
30
swung outwardly as shown, the channel strips
23 and the springs 24 being also removed. The
sash is inserted in the same way, the side leg
strips 29 being ?tted in place after the insertion
35
of the sash and the screws 4| being loosened to
permit the flap to resume its normal position with
the Weatherstripping in spring pressed engage
ment with the rail I5.
I have illustrated and described a preferred
40
45
ber constituting part of the wall of said curtain
box movably mounted thereon in opposed and
spaced relation to said ?xed frame member to
form a rail receiving space and adapted to be
moved toward and away from said rail whereby
in the position away from said rail the width of
said space is increased and said window sash
may be diagonally inserted in or removed from 10
said channel guides, and spring means normally
pressing said member toward said rail.
3. In a window structure, a frame including
side posts, vertical channel guides carried by
said side posts, a window sash engaged with said
channel guides and having a top rail, a ?xed
horizontal top frame member at one side of said
top rail, a curtain box at the upper end of said
frame and at the other side of said rail, a mem
ber constituting part of the wall of said curtain 20
box movably mounted thereon in opposed and
spaced relation to said ?xed frame member to
form a rail receiving space and adapted to be
moved toward and away from said rail whereby
in the position away from said rail the width of
said space is increased and said window sash
may be diagonally inserted in or removed from
said channel guides, weather-stripping means
carried by said member arranged to engage said
rail, and spring means normally pressing said 30
member toward said rail.
4. In a window structure, a frame including
side posts, vertical channel guides carried by said
posts, a window sash engaged with said chan
nel guides and having a top rail, a ?xed hori 35
zontal top frame member at one side of said top
rail, a curtain box at the upper end of said frame
and at the other side of said rail, a spring pressed
and satisfactory embodiment of the invention,
hinged ?ap member constituting part of the wall
but it will be obvious that changes may be made
of said box disposed in opposed relation to said 40
?xed frame member to form a rail receiving space
therein, within the spirit and scope thereof, as
de?ned in the appended claims.
Having thus described my invention what I
claim and desire to secure by Letters Patent
