Edward M. Buchach, Milwaukee, Wis., assignor to
Howard Safety Window, Inc., Milwaukee, Wis.,
a corporation of Wisconsin
Application December 30, 1935, Serial No. 56,734
4 Claims.
This invention appertains to window construc
tions of the type wherein the sliding sashes are
arranged to be swung inwardly relative to their
window frame for ventilating purposes and to
facilitate cleaning both sides of the glass panes
of the sashes.
(C1. 20—49)
the sash guides and for eliminating objection
able click as the catches and latches ride past
the grooves in the guides.
A further object of my invention is the pro
vision of means for detachably and pivotally con
5
necting the sashes with the slide plates, whereby
The present invention generally seeks to im- ' ease of operation of the swinging sashes is as
prove that form of window shown in my prior
Patent No. 2,038,266, issued to me April 21, 1936,
it) whereby a durable, e?icient, and fool-proof win
dow will be had, which will be easy to operate
by the ordinary housewife, and which will be
acceptable to the trade both from a manufac
turing and installation standpoint.
Another primary object of my invention is to
improve the construction of ?xtures for sliding _
and swinging window sashes, whereby the use of
springs and other complicated mechanism which
‘20
might be subjected to undue wear and break
age, is eliminated, and whereby ease of operation
is insured.‘
Another object of my invention is to provide
sured without danger of accidental displacement
of the sashes from the slide plates.
With these and other objects in view, the in 10
vention consists in the novel construction, ar
rangement, and formation of parts, as will be
hereinafter more speci?cally described, claimed,
and illustrated in the accompanying drawings, in
which drawings:
Figure 1 is a longitudinal section through a
window constructed in accordance with my in
vention, showing the sashes in dotted lines in
their fully swung-open position to facilitate the
cleaning of the glass panes thereof.
Figure 2 is an enlarged, fragmentary, front ele
vation of a window constructed in accordance
improved ?xtures for sliding and swinging sashes,
with my invention, with the bottom sash in its
whereby an ordinary window can be readily con
25 verted into a combined sliding and swinging
partially raised position ready to be swung into
window.
I
'
Another important object of my invention is to
provide novel means for forming the tracks and
weather strip stops for the upper and lower
30 sashes, whereby the same can be folded from a
single strip or piece of sheet metal.
A further object of my invention is to provide
novel slide members mounted in the channels
of the side guides for pivotally supporting the
sashes, with novel sash cord-operated catches
for engaging in grooves formed in the edges of
the tracks and window frame, when the sashes
are in a predetermined raised position and swung
into a room, so that accidental sliding movement
4O of the sashes is prevented.
A further salient object of my invention is the
provision of manually operated latches carried
by‘ the sashes adapted to move through said
grooves when said latches are actuated, to, permit
45 the swinging of the sashes into their vertical or
angular positions, the latches providing auto
matic means for releasing the catches when the
sashes are in their vertical planes, to permit in
50
tentional raising and lowering of the sashes.
A further important object of my invention is
the provision of wear and stop guide plates car
ried by the slide plates for the sashes arranged
adjacent to the swinging sash cord-operated
catches for partially engaging the manually oper
55 able sash latches, so as to reduce undue wear on
20
a
room.

Referring to the drawings in detail, wherein
similar reference characters designate corre
sponding parts throughout the several views, the
letter F generally indicates a window frame for
the sliding and swinging top and bottom sashes
25 Ill and H.
The window frame is of the ordinary
construction and includes the side stiles I2, the
lintel l3, and the sill l4.

Secured to the inner faces of the stiles I2 are
my novel guides and weather strip stops l5 for
the sliding and swinging sashes.
In my patent heretofore mentioned, the tracks
and weather strip stop beads for the sashes were
of an integral structure and extruded, and in the
present construction, the same are preferably
formed from a single strip of sheet metal bent
and folded into the desired shape. Thus, the
metal is folded to provide channels "5 and I‘! for
the upper and lower sashes l0‘ and H connected
together by integral web 18, the sides of which ex
tend beyond the adjacent walls of the channels
to form ?anges l9 and 26. One side wall of the
channel I‘! below the flange 20 is folded to pro
vide a guide ?ange 21 for the channel, and the
opposite wall of this channel is bent in to form
the opposite guide ?ange 22. The wall of the
channel l6 opposite the ?ange I9 is folded inter
mediate its ends to provide a guide ?ange 23,
and the extreme outer edge of this wall is' bent
inwardly, as at 24, to form the bead or stop
50 for the sash-carried weather strip.

neck entrances, I can provide slotted bearing
grooves 32, as shown in Figure 6 of the drawings,
and thus round pivot pins 33 can be carried by
the slide plates 25 and 26 and slipped directly in
the grooves from any position.
In order to hold the round pivot pins in place 10
machine screws 34 can be threaded into the cast
Figure 10 is an enlarged, fragmentary hori
10 zontal section taken through the window on the

sashes can be entirely disconnected from the slide
plate. This forms a convenient means for as
sembling the sashes in the window frames.
In lieu of utilizing ?attened pins and restricted
with the heads thereof overlying the pivot pins.
This reduces all hazard of the sashes being acci
dentally disconnected from the slide plates by a 15
housewife. The side edges of both sashes have
rigidly secured thereto metal wear strips 35, which
are adapted to ?t closely against the slide plates
25 and 26 when the sashes are in their vertical
positions.
The sashes and the slide plates can be balanced
in any preferred manner, and in the present in
stance I have illustrated sash cords 36 and 31 for
the upper and lower sashes respectively, and
these cords can be trained over suitable pulleys 25
(not shown) and their outer ends provided with
the window weights. The inner ends of the sash
cords 36 and 31 are provided with eyes 38, into
which are adapted to be placed the bills of hooks
39. These hooks 39 are associated with the slide 30
plates in a novel manner, which will be later de
scribed.
Referring back to the window frame, it will be
noted that the inner faces of the stiles are pro
vided with outwardly ?ared guide grooves 40, the
inner restricted ends of which communicate with
notches 4| formed in the ?anges 22 and the side
walls of sheet metal guides. The walls of the
grooves 40 carry any preferred type of metal wear
plates 41!)’, which also function to give a ?nished 40
appearance to the frame.
The grooves 40 and 4| are provided for the
lower sash, as will be later described, and the con~
necting portion l8 of the guides with its ?anges
l9 and 20 are cut away to provide grooves 42. 45
These grooves are arranged above the grooves 40'
and 4| and are provided for the upper sash, as
will also be later described.
,
Both the upper and lower sashes are provided
with novel latches for holding the sashes in an 50
upright position and against swinging movement.
The ?anges l9 and 23 form a part of the chan
nel [6, which acts as a guide for the slide plate All of these latches can be constructed in the
25 of the upper sash I0, while the ?anges 2| and . same manner, with the exception that the latches

cludes a rigid latch lug 44 and a sliding latch
duplicated on the other side of the window. _All
of the slide plates 25 and 26 are provided with lug 45. The latch lug 45 extends through a slot
46 formed in the metal wear plate 35 on the side
pads 21 which ?ll up the space between the inner
walls of the channels and the ?anges 23, [9, 2|, of the sash, and the lug 45 is movable toward

downward, and the movable lug 45 away from the
immovable lug,44.. An operating handle 5|~ ex
tends out of the face plate 41 and beyond the
front face of its sash, so that the same can be
conveniently manipulated. Normally, the latch
lugs 44 and 45 of the upper sash ride against the
inner edge of the ?ange l9, and the lugs 44 and
45 of the lower sash normally ride against the
inner edge of. the flange 22 to hold the upper and
10 lower sashes against outward swinging move
ment.
In order to swing open the sashes, the sashes
are raised until their rigid lugs 44 register with
the grooves 40, 4|, and 42, at which time the
15 handles 5| can be manipulated for moving the
movable lugs 45 toward the rigid lugs 44, so as
to lift the movable lugs into registration with
the guide grooves. After the lugs have been
raised, the lugs 44 and 45 can be moved through
the grooves and the ‘sashes swung out.
It is highly desirable to hold the slide plates
25 and 25 against movement when the sashes are
in their swung-open position, and hence I have
provided novel catches 52 for this purpose.
These catches 52 are pivotally connected at their
lower forward corners, by means of pivot pins 53,
to the upper ends of the slide plates, and the
upper forward ends of the catches are provided
with laterally extending ears or detents 54.
The hooks 39 for the sash cords have their
lower ends connected by means of pivot pins 55
to the catches 52 at one side of the pivot pins 53,
and hence the sash cords with their weights nor
mally tend to swing the catches on the pivot pins
53, and the detents 54 toward the ?anges l9 or
22, as. the case may be. Thus, when the sashes
are raised and swung to an open position, the de
tents will be swung into the grooves 4| or 42, as
the case may be. Obviously, this will effectively
40 hold the slide plates and the sashes against
sliding.
'
When the sashes are swung to a closed position,
the lugs 44 and 45 will ride into the ?ared en~
trances of. the grooves 40 or 42, and the lug 45
will be moved toward the lug 44 by the lower
wall of the groove. As the sashes reach their
vertical positions the lugs will strike the detents
54 and swing the catches 52 back, and the de
tents out of the grooves. This will allow slid
50 ing movement of the slide plates and sashes.
When the lug 45 moves back to its normal position
away from the rigid lug 44, entrance of the lugs
into the grooves will be prevented.
‘In Figures '7, 8, and 9 I have shown a slightly
modi?ed and preferred form of the window sash
latches, and in this form rigid and movable lugs
56 and 51 are provided, and the inner edges: of they
lugs overlap. The outer edges of the lugs are
bent laterally to form stops 58. The sliding lug
60 5‘! is carried by a latch plate 59, which is actuated
by a thumbpiece or handle 50.
In order to prevent Wear on the metal guides
and to eliminate objectionable click as the window
latches ride past the notches, I provide a novel
guide and wear plate 6|, which is clearly shown
in Figure 8. This guide and'wear plate BI is
rigidly secured by means of. pins 62, with the
upper ends of the slide plates, and the bottom
portions of the wear and guide plates lie on the
70 inner face of, the slide plates and are provided
with outwardly extending right angular wear
?anges 63.
As illustrated in Figures '7 and 8, the wear
?ange 53 rides against the inner edge of the
75 ?ange I9 or 22, as. the case maybe, and this
?ange 63'is so disposed as to form a stop for the
swinging slide plate latches when the same are
swung into the grooves.
When the sashes are in their vertical positions
with the movable latch lugs 51 away from the
rigid latch lugs, the same lie between the catches
of the slide plate and the inner face of. the wear
and guide ?ange 63. Thus, the latch lugs do not
engage the walls of the channels of the guide
members, and hence do not click against the
inner ends of the walls of the grooves. This is
an important feature and facilitates the ease of
raising and lowering the sashes.
By referring to Figure 1, it will be noted that
when the sashes are raised and then swung to 15
their extreme open position, the lower sash rests
against the sill adjacent to its outer end, and the
top sash rests on top of the lower sash. By
this arrangement, an e?ective rest is formed for
the sashes without imparting undue stress on the
slide plates, and hence breakage of. the sashes
and their ?xtures is eliminated. When the
sashes are in their full open positions, the oppo
site faces of the window panes can be easily
cleaned.
‘
25
The lower sash is also provided with a ventilat
ing position, and to permit the same to be swung
into such position, the inner faces of the stiles
i2 of the window frame and the adjacent portion
of the metal guides are grooved, as at 55. These
grooves terminate short of the front edge of the
window frame.
'
When it is desired to ventilate a room without
creating any draft, the lower sash is slightly lift
ed, and when the sash latches are in correct posi
tion relative to the groove 55 the movable lugs
are actuated and the sash is swung forwardly
with the lugs riding in said grooves. The lugs
engaging the front walls of the grooves prevents
further movement of the sash. The lower end of 40
the sash rests on the sill, and hence the entrance
of the air into the room will be above the lower
sash only.
From the foregoing description it can be seen
that I have provided a window of the combined 45
sliding and swinging sash type, which will oper
ate efliciently under all conditions and which is
substantially fool-proof.
The wear plates 35 on the sides of the sashes.
carry weather strips 65 formed of felt or the like, 50
which are adapted to engage under the ?anges
20 and 24 when the sashes are in their vertical
position. . This is similar to the construction
shown in my mentioned co-pending application.
Changes in details may be made without de 55
parting from the spirit or the scope of this in
vention, but what I claim as new is:
