COMPLETE SPECIFICATION.
Improvements in Hinged or Casement Windows.
I, JAMES WILLIAM GLAZIER, of 10, Shounden Terrace, Bohemia Road, St.
Leonards-on-Sea, in the County of Sussex, Metal Worker, 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 improvements in hinged or casement windows, and has
for its object to so construct such windows whereby they may be readily opened
either into a room or the like, or outward therefrom, the operation of opening such
windows being simple and expeditious, and readily performed in such a way as
to obviate the risk of accidents occurring to the operator or to the windows.
In order that this my said invention may be the more readily understood and
carried into practical effect, reference is hereby made to the accompanying sheet
of illustrative drawings, wherein; -
Fig. 1, is an elevational view from the inside of a window, in accordance with
my invention.
Fig. 2, being a section through same upon line A--B.
Fig. 3, is a similar view to Fig. 1, but from the outside.
Fig. 4, being a section upon line X-X.
Fig. 5, is a detail view, partly in section, shewing the operation of the pivoted
catch, and Fig. 6, is an enlarged section of one of the vertical sides of the window
upon line Y-Y (Fig. 1)..
Referring to the drawings wherein like letters and figures of reference indicate
corresponding parts wherever occurring throughout the several figures, a repre-
sents the fixed frame of the window, which frame is of hollow construction in sec-
tion, or in other words, has a deep rear flange a and a shorter flange a² in front.
To the front flange of one of the vertical sides of the fixed frame, a second frame
is hinged at 1, the latter frame being of similar construction to that of the fixed
frame a,
but of somewhat smaller size so as to allow of the said second frame fit-
ting within the first frame. The said second frame b is in a reverse position to that
of the fixed frame a, that is to say, the flanges of one frame oppose those of the
other.
Hinged at c to the rear vertical flange 62 of the second frame is a central
frame c having rear flanges c² and front flanges, which flanges are given opposite
directions, as shewn.
The said central frame c, which is the one that is glazed, is adapted to fit within
the frames a and b and to move outward independently of the others through the
fixed frame a, or together with the frame b, inwardly in the manner hereinafter
pointed out.
Pivoted catches & are provided upon the vertical meeting rail of the fixed
frame a, such catches having projecting lugs on one side, which, when the said
catches are turned in a certain direction, project over the vertical side of the
frame b, and lock the two frames a and b together.
When in this locked position, the central frame e çan be turned upon its hinges

page_text: outward through the fixed frame a, as indicated in Fig. 4, and when it is desired
to open the window inwardly, the frames b and c are locked together by means
of the locking-lever e, the catches & are turned on their pivots to the position in-
dicated in solid lines in Fig. 1, and dotted lines in Fig. 3, and the two frames b
and c locked together in the manner before described are swung inwardly upon
the hinges b', as indicated in Fig. 2, The locking-lever e, which is of any suit-
able well known construction, is pivoted upon a lug f on the vertical side of the
central frame c.
Suitable means, (not shewn) may be provided for securing the frame c at any
convenient position when opened outwardly.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is;
CLAIMS.
1. The improvements in hinged or casement windows, consisting in a fixed
frame having front and rear flanges, to which is hinged a second flanged frame
having a central frame hinged thereto, the said central frame being adapted to
open outwardly upon its hinges, independently of the other frames, and to be locked
together with the said second frame and be opened inwardly in conjunction there-
with, substantially as described and illustrated.
2. In hinged or casement windows, the fixed frame a having rear flanges a¹ and
front flanges a², to which frame is hinged a second smaller frame b which, when
closed fits within the said fixed frame, a third or central glazing frame e being
hinged.to the second frame and fitting within same when closed; in combination
with catches d, pivoted to the vertical side of the fixed frame opposite the hinge
side thereof, said catches having projecting lugs d' on one side which, when said
catches are turned on their pivots, lock the frames a and b together; and lug f
upon the frame c carrying a locking-lever for the purpose of locking the said
frames b and c together all arranged, combined, constructed, and operating, sub-
stantially as and for the purpose set forth, and as illustrated by the drawings.
