relative to‘ the frame. The glass sheet ‘I is

of glass with the space between the sheets sealed
against communication with the atmosphere:
5 The window is of the ‘type which may be opened
to permit the cleaning of the inner faces of the
glass sheets or to permit the ready replacement
of one or both sheets in case of breakage, and
in which each sheet is seated and'secured in its
10 own frame, one of which is ?xed and'the other
movable. One of the objects of‘ the .invention
is the provision of a structure of the kind speci?ed
having improved means for securing the movable
frame releasably in the ?xed or stationary frame,
15 with the sealing and spacing means between the
glassy sheets under compression without the use
of screws, thus facilitating the rapid and conven
lent assembling and disassembling of the two
frames. A further object is the provision of a
very compact simple structure permitting the
20
use of frames which are not too heavy and bulky
for use in ordinary wood sash. A still further
strips l6 of rubber or other suitable yielding ma- .
terial. The wedge :?ts down into a recess ll in
the frame it and whenpushed down tightly into
position provides a secure means for anchoring
the glass sheet in its frame when the movable ,
frame H is removed. ,The wedge is preferably
of relatively well vulcanized rubber so‘ that it '
presents an adequate degree of resistance against 10
any movement of the glass sheet ‘l to the right
before the application of the-movable frame it.
The glass sheet 8 in the movable frame ii is I
secured in position by means of a wedgestrip
whose lower portion 118 is shaped similar to the
wedge it, but which has integral with its upper
portion a sealing and spacing strip it. when
the frames are clamped’ together, this strip is is‘
placed undencompression between the faces of
the glass sheets and seals on the space 9 from 29
the atmosphere. This sealing member with its
wedge portion l B is preferably made in one mold- '

The two frames i0 and it are locked in. assem

that it lies partly in each frame member. When
the wire is forced into the position shown, it

separate frame it which fits‘ into a rabbet or
45 recess in the frame It], as indicated in Fig. 2,
the two frames being releasably clamped to
gether, as later described. A unitary structure
is, thus provided which may be clamped in a car
frame or seated in a wood sash of ordinary con
50 struction, such as the member I2 of Fig. 2.
The edges of the glass sheets are cushioned in
the recesses in the frames l0 and H by means
of the usual rubber strips l3 and I4 and each
frame is provided with an integral ledge l5 which

which extends clear around the periphery of the
window or it may be in a plurality of sections.
It provides a means for securely clamping the
frame sections together without the use of screws
or other similar holding devices which add to the
expense of a device of this kind and make the
operation of assembling and disassembling rela-(
tively tedious.

When it becomes necessary to take the frame
apart for cleaning the inner surfaces'of the panes
or for replacement of one of the panes, the wire

with a’ suitable tool and progressively detaching
it from the cam groove. This clears the way for
the removal of the frame I I and when such frame

The foregoing describes‘ the construction in
which the frame I l is removable from the frame
Hi. In many cases, it is desirable'that the frame
preferably made of rubber which is harder than '
25 ll, instead of being entirely removable, should
merely be hinged with respect to the frame Ill,
and this construction is illustrated in Fig. 3. In
this case, a piano hinge 22 is located in that
portion of the cam groove 2| located along one
30 side of the window, such side being ordinarily
the lower one. The hinge is provided with the
two sets of ?anges 23 and 24, which are secured
to the frames l0 and II by means of the screws
25. This provides a hinge connection which is
neat in appearance and does not project outside
the face of the frame II. It will be understood
that the other portions of the cam groove on the
other three sides of the window carry a locking
wire similar to the wire 20. The wire 20 may be
of copper or lead or some other suitable com
position, preferably somewhat ?exible, but if de
sired, it is possible to use some other form of
strip of circular cross section, such as a wire
surrounded by a coating of rubber or ?brous
material. It is also possible to use a cord of hard,
closely graded composition which is su?iciently
unyielding to provide the necessary compression
upon the sealing strip when it is forced into posi
tion in the cam slot.

compression, thus forming a seal, so that a seal
ing strip, such as- the member ll] of Fig. 2 is not
required. This renders the structure somewhat 20

the one heretofore described except that the
‘frame members 26 and 21 are secured together
by means of the clamping screws 28 instead of
the others, the lower portions of the wedges are
the upper portions, so that strength is secured
in the lower portions and resiliency tending to
the formation of a good seal is secured in‘ the
upper portions. It is desirable when this type oi’

wedgm 36 and 31 in one piece soihat no joints,
