Improvements in Windows.
1, WILLIAM LANG EDGAR, of 9 Lyndhurst Gardens, Glasgow, Photographer,
do hereby declare the nature of this invention to be as follows:
This invention relates to windows of that class wherein the sashes are hinged so
as to open into the room for cleaning and other purposes.
In carrying out my invention cacli sash is made in the form of a sliding frame
which is cut or checked out for the reception of an inner sash. This inner sash,
which is hinged at one side to the sliding frame, is glazed and is capable of being
turned and opened on the hinges like a door. When the inner sash is closed
into the sliding frame it can be locked by any suitable catch, bolt or such like.
In order to prevent ingress of rain or wind at the joints or spaces between
the inner glazed sash and the outer sliding frame, both may be suitably checked,
cut out, or stepped, or have beadings or the like provided.
The sliding frame is hung, as usual, upon the weight cords and can be raised
and lowered in the ordinary manner, whilst, at any time, the inner sash can be
turned inwards on its hinges for cleaning.
Checks are cut out of the frame and the inner sash for the reception of the
hinges.

I, WILLIAM LANG EDGAR, of 9 Lyndhurst Gardens, Glasgow, Photographer,
do hereby declare the nature of this invention and in what manner the same is
to be performed, to be particularly described and ascertained in and by the following
statement :-
This invention relates to windows of that class wherein the sashes are hinged so
as to open into the room for eleaning and other purposes.
In carrying out my invention each sush is made in the form of a sliding frame
which is cut or checked out for the reception of an iuner sash. This inner sash
which is hinged at one side to the sliding frame, is glazed and is capable of
being turned and opened on the hinges like a door. When the inner sash
is closed into the sliding frame it can be locked by any suitable catch, bolt, or
such like.
In order to prevent ingress of rain or wind at the joints or spaces between the
inner glazed sash and the outer sliding frame, both may be suitably checked, cut
out, or stepped, or have beadings or the like provided.
The sliding frame is hung, as usual, upon the weight cords and can be raised
and lowered in the ordinary manner, whilst, at any time, the inner sash can be
turned inwards on its hinges for cleaning.
Checks are cut out of the frame and the inner glazed sash for the reception of
the hinges.

page_text: And in order that my said invention may be properly understood I have here-
unto appended an explanatory sheet of drawings, whereon,
Fig. is a front view of the window closed.
Fig. 2 is a front view of the window with the lower sash turned inwards.
Referring to the drawings:-
:-
a is the window frame, is the lower sash and the upper sash.
As will be seen the lower sash is made in the form of a sliding frame & which
is checked out or stepped at for the reception of the inner glazed sash & which
is binged, at one side, at 6, 2, to the side stile of the sliding frame and is capable
of turning on the hinges like a door. d is a catch for locking the hinged sash to
the sliding frame.
The side stiles and top rail of the sliding frame are of wood but the lower
rail is constituted by a metal bar secured at each end to the side stiles. Tois
bar may he faced with wond if so desired. ſindicate screws for securing the bir
to the side stiles.
g is the window fastener, h are the nsual weights and the weight cords.
The upper sash e is constructed in a similar manner, with the exception that
the sliding frame e whilst having its side members of wood and bottom member
of metal, as indicated in dotted lines at in Fig. 1, has its top member broader than
the top member of the lower sliding frame so that the sash can be made to clear
the member of the lower sliding frame when the sash & is pushed up and the
sasli e pulled down in order to open it. If desired a strip of glass or a ventilator
may be inserted in the broad top incumber as indicated at j.
are the hinges and the catch for the upper sash.
It will be readily seen that whilst the sliding frames with their glazed sashes
can be raised and lowered as usual in the stiles of the window frame, the inner
glazed sashes can also at any time be opened inwards like a door.
Any suitable catel may be used for fucking the inner sashes.
If desired the top member of each sash may be strengthened by a metal backing
plate, or bar, or corner pieces.
Having now particularly described and ascertained the nature of any said inven-
tion and in what manner the same is to be performed I declare that what I
consider novel and desire to claim is :-
1. The combination of the sliding frame consisting of wood members with a
metal cross rail and an inner glazed sash hinged to said sliding frame, substantially
as hereinlefore described with reference to the drawings annexed.
2. The general arrangement and combination of parts of the window, substan-
tially as hereinbefore described and shown on the drawings annexed.
