PROVISIONAL SPECIFICATION.
Improvements in Casement Windows.
We, GEORGE EDWARD CLARE, Architect, of 66, Duke Street, Chelmsford,
ETHELBERT WAREHAM, Watchmaker, of "Ivy Dene," Goldlay Road, Chelmsford,
and SYDNEY UPSHALL, Commission Agent, of Springfield Road, Chelmsford, in
the County of Essex, do hereby declare the nature of this invention to be as
follows:
Our invention relates to improvements in casements or French windows, the
object of which is to provide means whereby the outside of such windows may he
easily cleaned by a person upon the inside, without in any way lessening the
weather proof properties of the said casement, as compared with such windows
as hitherto arranged.
For the purposes of our invention, for each door of the casement we provide a
pair of shaped metallic plates, one member of each of which we hinge or
otherwise pivotally connect to the vertical sides of the casement-window frame,
so the the other members of the said plates extend along the upper and lower
cross styles of the casement doors to the centre thereof, or thereabouts, the said
horizontal members of the said plates being thereat hinged or pivotally connected
to the said casements or doors, so that the latter are virtually suspended thereon
at their horizontal and vertical centres, suitable thumb-screws or their equivalents
being provided for securing the centre or other part of the length of the horizontal
members of the said plates to the said cross styles of the casements or doors, so
that these may open for ventilation in the usual way, the said plates then operating
as hinges therefor, but when the outside of the glass of the said casement or
doors is to be cleaned, upon the removal of the before mentioned thumb-screws or
the like, the casements may be swung round upon their points of suspension and
be reversed, so that their outer surfaces are brought inwards, when they may be
easily reached and cleaned, by a person situated on the inside, while in this
position.
Each pair of the said
shaped plates or compound hinges upon each door of
the casement, may be formed integrally with each other, or be connected by a
vertical bar or plate.

in the County of Essex, Architect, Watchmaker, and Commission Agent, respec-
tively. 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:-
Our invention relates to improvements in casement or French-windows, the
object of which is to provide means whereby the outside of such windows may be
easily cleaned by a person situated upon the inside, without in any way lessening
the weather proof properties of the said casement, as compared with such windows
as hitherto arranged.
In the accompanying drawings Fig. 1 is a perspective view of the improved
compound hinge, by means of which we suspend such casement doors or windows
for the purposes stated.
Fig. 2 is an elevational view of a casement window, to which such compound
hinges have been attached for suspending the same upon and within its frame.
Fig. 3 is a section taken upon the line A. B of Fig. 2.
The basis of our device consists of a pair of L shaped members F and G form-
ing the angles of the same shewn in Fig. 1, formed integrally with each other by
means of the vertical bar A. This construction is the only one which in our
experience gives reliable results in practice, as experience has shewn that there
is a liability to twist, warp or jam in window fastenings of this kind, which how-
ever is avoided by forming the L shaped members of the vertical bar into one
solid frame, which we prefer to make as a bronze or gun-metal casting. Hinges BB
are provided in the vertical bar of this solid frame, and other hinges H and H'
for connecting the solid frame to the casements or doors E, while the hinge
plates CC are attached to the vertical sides of the casement window frame. The
horizontal portions F G extend along the upper and lower cross styles of the case-
ment doors, to the centre thereof or thereabouts, the said horizontal nortions being
thereat attached by the hinges H H1, so that the doors are suspended thereon as
shewn, suitable thumb-screws or other fastenings may be provided for securing
the frame A FG, to the casements or doors E. as for instance at the points
marked XX, for the purpose of holding the said metallic frame, and the case-
ment firmly together, so that the doors may be opened for ventilation in the
usual way.
When the outside of the glass in the casement E has to be cleaned, the before
mentioned thumb-screws or other fastenings at X would be removed, when the
casement may be swung round upon its points of suspension H and H¹ (in the
direction indicated by the arrow in Fig. 3) and reversed, so that the outer surface
is brought inwardly, when it may be easily reached and cleaned by a person
situated upon the inside, while in this position.
We are aware that prior to our said invention, means have been devised for
suspending casement windows at their upper and lower ends, that such windows
may be reversed for cleaning, but so far as we are aware such means have not
been found to operate satisfactorily by reason of the insufficient stability of the
means employed, whereby the said casements got out of truth and refused to
close within their frames, but according to our invention these faults are obviated,
and the casements would be as rigidly supported as if actually hinged upon the
casement frame.
