PROVISIONAL SPECIFICATION.
Improvements in Fastenings for Hinged Windows and the like.
I, ARTHUR FRANK HEWITT, of 11 Redcross Street, Liverpool in the County
of Lancaster, Iron Merchant, do hereby declare the nature of this invention
to be as follows:-
This invention has reference to fastenings for holding hinged windows and the
like in any desired position, and it is specially applicable to casement windows.
The object of the invention is to provide a simple, cheap and effective fastening
which will not be an unsightly appendage to the window.
The fastening consists broadly of two main parts, a metal fixture which is
recessed into and firmly secured to the frame of the window opening, and a stay
bar, one end of which is hinged freely to the sash frame of the window, and the
other end constrained to slide along the said metal fixture by means of a pin in
the end of the stay bar running in a slot in the fixture, or by a like device. The
cross-section of the metal fixture is such that when recessed into the frame of
the window opening, the surfaces exposed to view are continuous, so that when
painted, there is no unsightliness such as is common to most forms of window
fastenings; with the same object, the stay bar and fixture are so arranged that
when the window is closed, the stay bar is completely concealed within or under
the fixture.
The window is fastened in any desired position by securing the stay bar to the
fixture so as to prevent sliding, and this may be effected in various ways. The
fixture may have a hinged lid provided underneath with rack teeth adapted when
the lid is shut down to engage with a projecting pin on the end of the stay bar
and so prevent it from sliding along the fixture. Or the rack may be detached
from the lid and adapted to be slid laterally into or out of engagement with the
said pin by means of a cam or the like attached to the lid and operated by shutting
or opening the latter.
In a simpler arrangement, the stay bar may be secured to the fixture in various
positions by means of a loose pin fitting in the stay bar and which can be inserted
in any one of a series of holes in the fixture, or by means of clamping screw
movable along a slot in the latter.
It will be seen that my invention is also applicable to sky-lights and the like,
and that the details may be modified without departing from the spirit of my
invention, the main features of which are that the surfaces of the fixture attached
to the frame of the window opening are continuous with the moulding thereof,
and that the stay bar is concealed by the said fixture when the window is closed.

COMPLETE SPECIFICATION.
Improvements in Fastenings for Hinged Windows and the like.
I, ARTHUR FRANK HEWITT, of 11 Redcross Street, Liverpool, in the County
of Lancaster, Iron Merchant, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
This invention has reference to fastenings for holding hinged windows and the
like in any desired position, and it is specially applicable to casement windows.

page_text: The object of the invention is to provide a simple, cheap and effective
fastening which will not be an unsightly appendage to the window.
The fastening consists broadly of two main parts, a metal fixture which is
recessed into and firmly secured to the frame of the window opening, and a stay
bar, one end of which is hinged freely to the sash frame of the window, and the
other end constrained to slide along the said metal fixture by means of a pin in the
end of the stay bar running in a slot in the fixture, or by a like device. The
cross-section of the metal fixture is such that when recessed into the frame of the
window opening, the surfaces exposed to view are continuous, so that when painted,
there is no unsightliness such as is common to most forms of window fastenings;
with the same object, the stay bar and fixture are so arranged that when the
window is closed, the stay bar is completely concealed within or under the
fixture.
The window is fastened in any desired position by securing the stay bar to the
fixture so as to prevent sliding, and this may be effected in various ways.
In the accompanying drawings which illustrate my invention I have shown
sonie of the various ways, which I have found convenient in practice, whereby the
sliding end of the stay bar is secured in the desired position.
Figs. I and II show the clamping screw moving in the slot. Figs. III and IV
show the sliding rack. Figs. V and VI show arrangements where a pin secures
the sliding end of the stay in any one of a series of holes in the fixture, and
Figs. VII to XIV show arrangements where the lid of the fixture forms a rack
which, when in normal position, holds the end of the stay in any desired position.
The racks in these figures are, for clearness, shown with widely spaced notches or
holes but it is evident that where a variety of positions of the window is desired,
the notches or holes may be increased and the pitch reduced in which case the
rack approximates more closely to an ordinary toothed rack.
Throughout the drawings similar parts are indicated by the same reference
figures and in the case of sections the direction in which they are viewed is
indicated by the small arrows placed adjacent to the letters denoting the plane of
section.
1 is the frame of the window opening, 2 the sash frame of the window, 3 the stay
bar, 4 the hinge fixing of the same, 5 is the metal fixture which is preferably let
into the frame so as to be flush therewith. The end of the stay bar slides along the
fixture and the latter is so recessed that when the window is closed the stay bar is
housed in the fixture as shown in Figs. IX and XIV.
In Fig. I the fixture has a slot 6 in which the pin 7, fixed to the end of the
stay, slides; the pin has a collar 8 to hold the stay up and a screwed portion for
the nut 9 which, when screwed down, secures the end of the stay in any given
position. The under surface of the slotted top of the fixture may be serrated, and
a lead washer 10 interposed, to ensure a better grip.
In Figs. III and IV the fixture 5 has a slot as before and the stay is provided
with a pin 7, in this case however the pin is held in the desired position by a sliding
rack 11 which is drawn into engagement with the pin by means of the screwed
projection 12 and nut 13. The rack is shown operated from the inside of a window
opening inwards but it may be operated from the opposite side where the window
opens outwards.
In Figs. V and VI the end of the stay is guided by a groove in the fixture and it
is maintained in any given position by the pin 7 which passes through a hole in the
end of the stay and any given hole of the series in the fixture. The hole 14 in the
stay is for holding the window closed. A recess 15 is formed where the window
opens inwards to house the pin 7 and its chain when not in use.
In Figs. IX to XIV the stay is guided as before in a slot in the fixture by a
pin 7 provided with a collar 8 to keep the stay up; the pin has a projecting end
adapted to fit in any one of the holes in the lifting rack 111 which is raised by the
knob 16 when the window is opened, and which, when the pin 7 is opposite the
suitable hole, drops into position and so holds the pin against sliding.

page_text: In Figs. VII and VIII the construction is similar to Figs. IX to XIV but in
these figures the fixture is shown on the window sash frame as in Figs. III and IV
and in order to enable the rack 11¹ to be raised when the window opens inwards a
finger plate 17 is provided; when the window opens outwards the finger plate is
placed as shown by the dotted lines.
In Figs. IX to XIV the rack 11' is shown for the sake of clearness as having
through holes in which the pin 7 engages. I prefer however not to carry the holes
through the top of the rack as they disfigure the arrangement. The under side of
the rack may instead of holes have teeth formed in the usual way but I prefer to
let the metal between the holes act as the teeth.
It will be seen that the fixture may be placed on the frame of the window opening
or on the sash frame of the window as may be desired and that the arrangement is
applicable to right or left handed windows opening inwards or outwards.
It will be seen that my invention is also applicable to sky-lights and the like, and
that the details may be modified without departing from the spirit of my invention,
the main features of which are that the surfaces of the fixture attached to the frame
of the window opening or the sash are continuous with the surfaces thereof, and that
the stay bar is concealed by the said fixture when the window is closed.
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 ;-
1. The improved window fastener which consists of a stay bar hinged to the
window frame or to the sash frame, the free end of which is guided in a fixture
attached to the sash frame or to the window frame as the case may be, the said
fixture being adapted to be let into the frame so as to be flush therewith, and being
recessed so as to house the stay bar when the window is closed and being provided
with means whereby the end of the stay bar may be secured in any desired position
in the fixture, substantially as described and illustrated.
2. The combination of the window frame 1, the sash frame 2, the stay bar 3, the
fixture 5 having a recess to house the stay bar, and a slot 6 in which the pin 7 is
guided, and the means for holding the said pin in any position in the slot,
substantially as described and illustrated in Figs. I and II.
3. In combination with the window frame 1, the sash frame 2, the stay bar 3, and
the fixture 5 having a recess to house the stay and a slot in which the pin 7 is
guided, the means for holding the pin 7 in any desired position which consist of the
sliding rack 11 adapted to engage laterally with the pin 7, substantially as described
and illustrated in Figs. III and IV.
4. In combination with the window frame 1 the sash frame 2, and the stay bar 3,
the fixture 5 having a recess adapted to house the stay when the window is closed
and having a groove adapted to guide the end of the stay bar and a series of holes
by which the latter is held in any desired position by the pin 7, substantially as
described and illustrated in Figs. V and VI.
5. In combination with the window frame 1 the sash frame 2, the stay bar 3, and
the fixture 5 having a recess adapted to house the stay bar when the window is
closed and having a slot in which the pin 7 in the end of the stay bar is guided, the
means for holding the said pin in any position which consist of a lifting rack 111
which when in normal position engages with the said pin, substantially as described
and illustrated in Figs. VII to XIV.
