METAL WINDOW
Charles D. Pilant, Alhambra, Calif.
Application November 9, 1936.!Serial No. 109,894
z claims. (c1. its-69)
My invention relates to a metal window and has
for its principal object the provision of a 'window
wherein a plurality of metal sash, each carrying
a glass panel, are mounted for simultaneous
l swinging movement in a. metal frame, and such
sash and frame having associated therewith
means constructed of metal for imparting swing
ing movement to the sash, thus providing a con
struction that is entirely fire-proof.
10 i
Further objects of my invention are to provide
a metal window having a plurality of glazed sash
that are burglar-proof by reason of the fact that
the small size of the individual sash prevents an
intruder from crawling through the opening in
l5 the sash, even though the panel of glass is en
tirely removed therefrom; further, to' construct
. the window frame and the sash so as to effectively
prevent rain from being blown by the window
through the joints between the edges of the metal
zo sash and the window frame.
A
Further objects of my invention are to provide
improved 'means for imparting swinging move
ment to the sash; further, to provide simple and
eflicient means for securing the sash operating
25 means so that the sash cannot be opened or closed
from the exterior of the window; and, further, to
provide a construction that will prevent the in
gress of dust while the sash are closed.
With the foregoing and other objects in. view
30 my invention consists in certain novel features of
35
horizontal flange II of said member lies against
the building wall at the top of the window open
ing and the vertical flange I2 lies against the
outer face of the building wall just above the 5
window opening.
ì
.,
‘
Vertically disposed side members of the win
dow frame include outer flanges I3 that occupy
the same plane with the ñanges I2 of top mem
ber I0, and said ñanges I3 overlie the outer face l0
of the building wall to the sides of -the window
opening. These upright members also include
vertically disposed plates or ñanges I4 that lie
against the faces of the building wall to the
sides of the window opening to the rain, and said l5
plates or ñanges are connected tothe ñanges
I3 by inclined plates I5.
The bottom member of the frame comprises
an outer iiange I6 that occupies the same plane
with the ñanges I2 and I3, and this ñange I6 20
lies against the outer face of the building wall
below the windowiopening therein. The lower
member also includes a horizontally disposed
plate or flange I1 that rests on top of the build
ing wall at the bottom of the window opening 25
therein and connecting the plates or ñanges I6
and I1 is an inclined plate or ñange I8. Formed
integral with or ñxed to the underside of plate
or flange II is a plate I9, and formed integral
with and depending therefrom are spaced par-. 30
construction and arrangements of parts that will
be hereinafter more fully described and claimed
and illustrated in the accompanying drawing, in
allel flanges 20 and 2l.
Extending downwardly and outwardly from
the front edge of plate I9 is an inclined plate
or flange 22; Formed integral with or fixed to

Referring by numerals to the accompanying
drawing which illustrates a preferred embodi
ment of my invention, I0 designates the upper
55 member of the window frame, which member is
the frame are inwardly presented parallel ñanges
23 and 24 which occupy the same planes re
spectively with the flanges 20 and 2I.
Formed integral with and projecting upwardly
from plate or flange I1 are spaced parallel_40
ilanges 25 and 26 that occupy the same planes
respectively with the fianges 20 and 23 and 2I
and 24.
Where4 the window is provided with four
swinging sash the ñanges 2l and- 26 are con- 45
nected by a vertically disposed bar 21 that oc
cupies a point midway between the upright side
members of the frame and connecting the inter
mediate portion of this vertically disposed bar
with the ñanges 24 on the upright side members 5o
are horizontally disposed bars 28.
Formed integral with or fixed to the upper
edges of the horizontal bars 28 are outwardly and ‘
downwardly projecting flanges 29 that are par
allel with the inclined flanges I8- and 22. Formed 55

2,112,084
integral with and secured to the outer face of the
vertical bar are inclined plates or flanges ll
against which the vertically disposed side mem
bers oi' the swinging sash are adapted to engage
when the sash are closed.
Connected by suitable hinges 3| to the lower
edge of the inclined flange or plate 22 are- the
inclined upper rails l2 of the sash frames and
the upper faces of which rails are inclined so
as to nt snugly against the under faces of the
flangesv 22 when’the sash are closed.
The upright side members or rails I8 of the
sash frames are inclinedV so as to fit snugly
against the inclined portions I5 of the upright
side members of the window frame and against
the inclined flanges I0 on rail 21 when the sash
are closed.
’I'he under faces of the lower rails 34 of the
sash frames are inclined so as to fit snugly against
the _inclined plate 2l and the inclined portion Il
on the latter is a worm wheel 41 and a pinion
4l that engages the teeth of rack bar 4I.
¢'
Projecting forwardly from the lower portion
of plate 44 is a bracket 49 in which are Journaled
the trunnions of a worm Il that engages the 5
worm wheel 41, and formed in the end of the ex
posedvtrunnion of this worm is a non-circular
recess Il that is adapted to receive the non-cir- „
cular end of a key or crank shaft l2 that is'uti
lized for rotating the worm.
.
10
Where this sash operating mechanism is used
the rotation of worm il by the crank or key 52
imparts rotary movement to worm 41 and thepinion 4l and the latter engaging the teeth of
rack 43 imparts longitudinal sliding movement 15
to bar Il.
Thus it will be seen that I have provided an
all-metal and glass window that is relatively sim
ple in construction, inexpensive of manufacture,
and very eifective in performing the functions 20
of the lower window frame member when the - for which it is intended.
sash are closed.
The size of the sash frames is such as to pre
All of the sash frames are preferably formed vent burglars or intruders from entering the
of metal rails, the ends of which are welded to
window after the glass in the sash has been bro
each other to provide integral structures.
It will be understood that the upper rails I2 of
the upper sash in the window frame bear against
the inclined flange 22st the top of the window
structure and that the upper rails of the lower
30 sash are hinged to the lower edge of the inclined
flange 29 and bear against the underside of said
inclined flange when the sash'are closed (see
Fig. 2).
,
Arranged for vertical sliding movement on the
35 inner face of the vertical bar 21 is a bar 35 in
the upper and lower portions of which are formed
slots 36, and passing through said slots» and
seated -in the bar 21 are hinged pins or screws
40
that retain the sliding bar against said bar 21.
Secured to the central part of the exposed face
of the sliding bar 35 is a knob 38 that is utilized
in raising and lowering said sliding bar.
Pivotally connected to the intermediate por
tions of the vertically disposed side members Il
45 of the hinged sash are the lower ends of links I9,
the upper ends thereof being secured to the sides
of the sliding bar I5. As a result of this ar
rangement the sash will be swung outwardly into
positions shown in dotted lines in Fig. 2, when
the sliding bar 35 is moved downwardly, and
when said bar is moved upwardly the sash will be
simultaneously closed.
Knob 3l is provided with a threaded shank
40 in order that, after the sliding bar has been
moved vertically in either direction, it'may be
secured in its shifted position by tightening the
knob so as to cause the inner end of the threaded'
shank to engage with clamping pressure against
the central portion of bar 21.
Removably positioned in the inner portion of
the window frame and hearing against the
flanges 2l, 28 and 25 is a metal frame carrying
a metal screen 4|, the same being retained ln
position within the frame by hooks 42 that are
65 rotatably mounted in the upper and lowerraiis
of the screen frame.'
- In Figs. 7 and 8, I have illustrated a simple
and convenient means for swinging the sash
upon their hinges and which means includes a
70 ‘vertically disposed rack bar 43 that is secured
on the face of the lower portion of the sliding bar
Il adjacent .one edge thereof.
Y Mounted on bar 21 adjacent the projecting por
tion of racky bar 42 is a plate 44 having bearings
75 45 in which is Journaied a shaft 4l and Secured
ken, thus providing a burglar-proof construction. 25
Inasmuch as the outer edges of the rails or sash
frames are inclined or bevelled and engage
against correspondingly inclined or beveled faces
on the window frame when the sash are closed,
ingress of dust and rain blown by the wind
through the window when the sash are closed is
effectively prevented.
-
By providing suitable means for locking the
sash to the window frame in closed position, my
improved window may be advantageously used
in jails, detention homes or other buildings where
persons are connned.
'
`
, It will be understood that minor changes in the
size, form and construction of the various parts
of my improved metal window may be made and 40
substituted for those herein shown and described
without departing from the spirit of the inven
tion, the scope of which is set forth in the ap
pended claims.
