I, WILLIAM BEWICK QUELCH, of Croft, near Darlington, in the County of
York, Civil Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to sash windows and has for object to provide improved
means for allowing the outsides of such windows to be entirely cleaned from
within.
According to my invention I make a part or parts of the window or a pane or
panes thereof movable or removable so as to present an aperture or apertures
through which access can be gained from within to otherwise inaccessible parts of
the window when requiring to clean the same, suitable fastenings being provided
for securing the said parts or panes in the windows when the apertures are
closed.

I, WILLIAM BEWICK QUELCH, of Croft, near Darlington, in the County of
York, Civil Engineer, 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 :-
My invention relates to sash windows and has for object to provide improved
means for allowing the outsides of such windows to be entirely cleaned from
within.
According to my invention I make a part or parts of the window or a pane or
panes thereof movable or removable so as to present an aperture or apertures
through which access can be gained from within to otherwise inaccessible parts of
the window when requiring to clean the same, suitable fastenings being provided
for securing the said parts or panes in the windows when the apertures are
closed.
To enable my invention to be fully understood I will describe how it can be
carried into practice by reference to the accompanying drawing in which :-
Figure 1 is an elevation partly in section of the inner side of a portion of a sash
window having a movable part or pane according to my invention:
Figure 2 is a transverse section; and,
Figure 3 is a plan of the same :
Figure 4 is a detached elevation of the movable part or pane; and,
Figure 5 is an elevation drawn to a reduced scale and shewing the window with
the movable part or pane raised to uncover the aperture therein.

page_text: A and B are sliding sash frames of ordinary construction and C and D are the
fixed panes or sheets of glass secured therein in the usual manner.
a is my movable pane which I preferably fix in a shield shaped frame b adapted
to turn upon a binge-pin c at one of the angles of a correspondingly shaped frame d
made with a groove e to receive the two side edges f, of the frame b. The side
edges g, g of the frame d are rebated, as shewn, to receive the edges of the aperture
cut in the fixed pane C to admit of my movable pane being applied thereto. The top
of the frame d is formed of two plates i, i fixed to the sides at such a distance apart
that they will allow the movable pane to pass between them when the latter is
raised as shewn by the dotted lines in Figure 1; j is a flange or lid on the top of
the frame which shuts down over the edges of the plates i, k is a spring catch
secured by a screw to the frame d and working between the plates i, i or within
the mortice in the sash frame such catch being adapted to engage beneath the
lowermost angle or point of the frame b when the movable pane is raised and in a
hole Figure 4 in the frame b when the pane is lowered so as to secure the pane
in either of these positions. When an ordinary sash fastener such as E is employed
to lock the sashes the bolt or arm F thereof can be placed so that when the movable
pane is closed it will project over the top of the frame b and also secure the movable
pane in its closed position.
With this construction when cleaning the window all portions thereof can be
reached by the hand from the inside, it being only necessary, in order to obtain
access to the portions which are usually inaccessible, (the parts being in the position
shewn in Figures 1, 2 and 3 of the drawing) to release the bolt or arm F of the
window fastener E and the spring catch A and then to turn the movable pane a in
the frame upon its hinge into the position shewn in dotted lines in Figure 1, in
which position it will be retained by the spring catch . The arm of the person
cleaning the window can then be passed through the aperture m within the frame d
in the fixed window pane C. thereby uncovered as clearly shewn in Figure 5. To
close the aperture mit is only necessary to withdraw the spring catch k when the
movable pane a can be turned down into the frame d as shewn in Figures 1 and 2
and the catch k will automatically lock it in position.
It will be obvious that two or more of my movable panes can be applied to a
sash window in case it be of such a size as to require more than one and, moreover,
the movable parts or panes can be arranged in other ways, for example, instead of
turning on a hinge as hereinbefore described and illustrated they can be adapted to
slide into their open and closed positions and be secured by means of any suitable
fastening.
Instead of employing a glazed frame as herein before described and illustrated,
the movable or removable pane may for the sake of cheapness simply consist of a
piece of glass without a fraine but I do not recommend this as it would probably
not be so serviceable and would not have such a neat appearance.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The construction, and application to sash windows, of a glazed frame movable
or removable so as to present an aperture through which access can be gained from
within to otherwise inaccessible parts of the window substantially as and for the
purpose herein before described.
2. A sash window having a pane adapted to move on a hinge in a frame secured
in one of the usual or fixed panes of the window so as to cover and uncover an
aperture such pane being secured in its closed and open positions by a spring catch
or other suitable means for the purpose set forth and substantially as hereinbefore
described and illustrated in the accompanying drawing.
3. A glazed frame adapted to move or slide in a frame designed to be fixed in
the meeting rail of a sliding sash, and constructed and operating substantially as

page_text: hereinbefore described and illustrated in the several figures of the accompanying
drawing.
4. A frame designed to be fixed in a sash window and having a glazed frame
movable or removable therein for the purpose set forth and described.
5. An apparatus consisting of a frame and a glazed frame movable therein or
removable therefrom to be fixed in a sash window for the purpose set forth and
described.
