Improvements in Windows to Facilitate Cleaning the same.
I, FRANK CAREW CAREY, of 176, Portnall Road, Harrow Road, W., Joiner, do
hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in windows and has for object to so
construct the sashes that the window may be easily cleaned from the inside.
For this purpose I combine the advantages of the ordinary sliding sash with
those of the French window or sashes opening on hinges. The upper and lower
sashes are each formed of two hinged portions or halves opening from and closing
together at the centre. The said two halves of the sashes are each pivoted or
hinged to a stile sliding in guides on each side of the window frame so as to
open inwards, and the said halves are locked together by a sliding bolt or other
suitable catch, fitted underneath them or in any other convenient position so that
they form a single frame or sash which can be raised or lowered in a similar
manner to ordinary sliding sashes. The upper and lower sashes are locked to-
gether by an ordinary window fastener fitted to the meeting-rail of one of the
upper and lower halves of the sashes. In order to clean the lower half of the
window the lower sash is raised clear of the inner beading and the two halves
are unlocked and turned inwards so that the window may be cleaned on both
sides from inside the building. The upper sash may be similarly cleaned by
drawing it down, unlocking the two halves, and turning them inwards, having
previously raised the lower sash or not as desired. The stiles are grooved to
engage with plates or strips on each side of the window which act as guides.

I, FRANK CAREW CAREY, of 176, Portnall Road, Harrow Road, W., Joiner, 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 the construction of windows by
means of which the same may be easily cleaned from the inside, and consists in
forming the sashes of two hinged portions which can be opened inwards and closed
together at the centre.

page_text: The two halves of the sashes are pivoted or hinged to a stile sliding in guide
on each side of the window frame, and the said halves are locked together by a
sliding bolt or other suitable catch, fitted underneath them or in any other con
venient position, so that they form a single frame or sash which can be raised o
lowered in a similar manner to ordinary sliding sashes. The upper and lower
sashes are locked together by a window fastener fitted to the meeting-rail of one
of the upper and lower halves of the sashes.
In order to clean the window the sashes are raised or lowered clear of the lower
and upper beading.
The two halves are then unlocked and turned inwards so that the window may
be cleaned on both sides from inside the building. The stiles are grooved to
engage with plates or strips fixed to each side of the window frame and serving
as guides to the said stiles.
The accompanying sheet of drawings illustrate a window frame according to
my invention, Fig. 1 being an inside elevation, and Fig. 2 being a cross section
of the same to a larger scale. Fig. 3, is a horizontal section through the frame
and the two sashes.
a is the frame of the window and b are the stiles of the upper sash whilst c are
the stiles of the lower sash both sets of stiles being fitted to slide between the
parting bead a' and the frame a.
d, d are the two halves of the upper sash, and e, e¹ are those of the lower sash.
The two halves d, d' are hinged or pivoted at f to the stiles b, and the two
halves e, el are hinged or pivoted at g to the stiles c. h, h are the metal plates or
strips fixed to each side of the frame a, on the inner side of the window, and
engaging with grooves h¹ formed in the stiles c so as to act as guides to the said
stiles in their vertical movements, and i, i are similar strips, fixed to each side
of the frame on its outer side, and engaging with grooves in the upper stiles b
for a similar purpose.
It will thus be seen that the stiles b and c slide between
the frame a and the parting bead a' the strips and i securing them in position
to the frame a.
k is a sliding bolt fitted to the lower part of the frame e¹ of the lower sash and
engaging with eyes or sockets on the frame e so as to lock the said frame or two
halves of the sash together to constitute a single frame. The handle of the
bolt is turned down flush with the sash, when closing the latter, so as to lie behind
the lower part of the frame a, if necessary. m is a similar bolt or fastener fitted
to the underside of the frame d' of the upper sash and engaging with the eyes
or sockets m¹ on the frame d for locking the said frames or halves of the upper
sash together. It is evident that other arrangement of fastener may be employed
providing they do not interfere with the motion of the sashes, and that they may
be fitted in other positions. I also prefer to use a third bolt which is flush on
the face of the top rails of upper sashes. n is a horizontal metal strip fitting into
a groove in the underside of the frames c, el, and fixed to the lower part of the
frame a, for holding the said frames rigidly together in their closed position.
o is a metal strip fixed to the frame d and engaging with a recess or rabbeted
edge of the frame d', when the said frames are closed, thereby acting as a draught
or weather excluder, and p is a similar strip fixed to the frame e and serving the
same purpose for the lower sash. 9 are beadings or projecting strips formed on
the insides of the stiles and engaging with grooves in the sash frame which when
the sashes are closed also serves as draught or weather excluders.
ordinary balance weights attached by cords passing over pullies, to the stiles.
In order to clean the window the lower sash is raised clear of the horizontal
frame a. The frame e, e¹ are then unfastened by pushing back the sliding bolt k
and they are turned inwardly on their hinges, as shown in dotted lines Fig. 3,
and after being cleaned outside they are closed, bolted together, and raised. The
upper sash is then lowered, the bolt m unfastened, and the two frames d, d¹ turned
inwards similarly to the frames e, e¹. By this means the windows of both the
sashes may be easily cleaned on both sides from inside the building.

page_text: 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:-
(Claim 1). The improvements in windows comprising the sliding sashes each
formed of two frames hinged to separate stiles and connected rigidly together
by a fastener, the said stiles sliding in guides or grooves on each side of the
window frame and being connected to ordinary balance weights substantially
as described.
(Claim 2). In an improved window the combination with the frame a of the
sliding stiles b and c, the two halves d, d of the upper sash, the two halves e, e¹ of
the lower sash each provided with hinges f and g respectively, metal strips h
engaging with grooves h¹ in the stiles c, and strips i engaging with grooves i¹ in
the stiles b, bolts or fasteners k, m, and eyes or sockets 1, m³, metal strips n, o, p,
beading q, and balance weights r, all arranged and operating substantially as
described and for the purposes specified.
