Improvements in or relating to Doors and Windows.
I, JOSEPH SINCLAIR FAIRFAX, of 433, Strand, in the County of London,
Consulting Engineer and Patent Agent, 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, as communicated to me by my foreign correspondent, relates to a
new method of hanging doors and windows which enables them to be opened in the
ordinary way and also upon horizontally placed pivots so as to present openings
above and below an horizontal axis.
In the case of ordinary balcony windows which open sideways, (like a door), it
is, as a general rule, impossible to air the room without at the same time giving
rise to draughts liable to affect injuriously the health of such persons as may be in
the apartment. In the second place, also, when the window is opened, persons
outside can plainly see into the room and the privacy of the occupants is interfered

disadvantages are obviated by the pivoted window.
With the latter however it is difficult to look out (or at any rate to put one's
head out) and it impossible to make use of the window as a door for the purpose
of stepping out on to a balcony. The improved window possesses none of these
disadvantages, but combines the conveniences of both systems at one and the same
time without suffering from the drawbacks of either.
The accompanying drawings serve to illustrate the invention:
Fig. 1 is a front view of a window.
Fig. 2 is a vertical section of same.
Fig. 3 is a view showing the arrangement of the pivoted portion of the window
in the frame.

frame is made in the ordinary way, except as hereinafter stated, and of suitable
materials and dimensions. B is the hanging style to which the sashes F F are
hung. The sashes are attached to the hanging style by means of hinges, and it is
kept shut by a bolt or other device. CC are the pivots on which the hanging
style B turns in the frame A. In the drawing the pivots are shown as attached to

arrangement may be reversed. D is a bolt for securing the style B to the frame A
when it is not desired to rotate it on its pivots. E is a rack attached to the wall
or jamb of the window to enable the sash to be secured at any point when it is
opened by rotating it, or any equivalent device may be used for the purpose.
To render the joint between the frame and style A and B airtight and to prevent
the entry of air when the window is closed I have provided each one with a double
or reverse rebating, a, b, and a¹, b. The rebating being arranged at the height
of the pivot in opposite directions so that when the sash is closed and not
rotated, the projection of a exactly fits the rebating of b. This arrangement has
the additional advantage of preventing the sash from turning round in the wrong
direction which might often cause accidents.
G is a plate of metal or other suitable material attached to the bottom of the
moveable frame B by a hinge which enables it, when the moveable sash is rotated,
to assume a vertical position and so prevent the entry of gusts of air.
The method thus described in detail in relation to windows may be applied in
the same way to doors. The arrangement is precisely similar consisting of the

fittings and all the details are, in short, the same in both systems with the exception
of the plate G, which is omitted, and it is consequently unnecessary to repeat the
description.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :
In windows and doors for buildings, the combination of a stationary frame A and
a moveable hanging style B having pivots C and adapted to swing thereon in the
frame A and to fit closely therein by the reverse rebating, with sashes or a door
hinged to the said style B, substantially in the manner and for the purpose herein-
before described and illustrated by the drawings.
Dated this 14th day of November 1891.
