COMPLETE SPECIFICATION.
Casement Stay and Fastener Combined.
I, FREDERICK WILLIAM BAKER, of Oakfield House, Edgbaston Road, Balsall
Heath, Birmingham, in the County of Worcester, Architect, 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 pertains to a casement or window stay or fastener, or a combined
casement stay, fastener and stay holder.
Figure 1 of the accompanying d'awings, represents a side hinged, and outwardly
moving window or casement, fitted with a combined stay and fastener, constructed,
arranged and provided according to my invention.
The window frame is shown partially opened, whilst the dotted lines represent
the stay hanging down, or in a position as when the same is out of use.
Figure 2 represents partly in horizontal section, and partly in elevation, the said
combined stay and fastener."
In this view, the fastener part is shown in section, and so also is the framing.
The position of the window is shown open to the first eye of the adjustable stay.
Figure 3 represents a side elevation of the said combined apparatus Figure 2,
and also front elevations of portions of the window and framing.
Figure 4 represents a front elevation of the said combined appliance with the
window closed.
Figure 5 is a cross section upon the dotted lines A. B. Figure 4, showing the
connection of the catch with the slot within the staple plate, let within the stile
or upright of the window frame.
Figure 6 shows the catch or fastener, combined with a stay-connection hook,
upon which one or other of the eyes of the stay takes.
The same letters of reference indicate corresponding parts in the several figures
of the drawings.
a is an adjustable stay, consisting of a quadrant-shaped bar, having eyes or
loops a², formed or located upon the window or casement side of the said bar, and
which eyes, which are arranged at equi-distances apart, are adapted to take over
and upon a hook 63, of a depending arm b², connected to a pivoted or turning
catch b, jointed at 6', to an attachment or carrying plate c, secured to the inside
face d', of the upright stile d², of a window or casement d.
This said combined catch and stay hook, is alike in shape to a bell crank lever,
[Price 17

page_text: with the hook part depending downwards, and with the catch part, which is simply
an outstanding arm, tongue piece, or their equivalents, directed outwardly, and
normally kept in that position by the hanging end of the hook part.
The inner end a³, of the stay. is jointed at a', to a supplementary carrier or
attachment a, swivelly connected to a staple plate, having a catch slot, by a
headed pivot a', and which plate, is attached to the inside 2, of a stile e¹, of the
frame e, of the window or casement.
The said side e², is opposite to the hinged side of the framing.
In use, for keeping the window open, or partly open, one or other of the eyes or
loops a², take over and upon the erect hook end 63, of the combined hook and
catch b.
On closing the window, the said stay is turned upwards, one or other of the eyes
removed from the booked end, and the window closed as in Figures 4 and 5.
When in this position, the arm or tongue piece b, takes into the sinking or slotted
gap, 3, of the staple plate f, and is retained there by the counterpoised depending
arm of the same.
I propose that the arm or tongue piece b, shall be shamfered off on its inside
presented edge, so that the catch may if necessary, be made self-acting, on the
closing of the window or sash, although the said catch may be put into position by
hand, and there affixedly secured by a shamfered edge.
If desired, the catch may be independent of the stay-holding hook, or the
stay-holding hook may be independent of the catch.
The stay may, if necessary, be made from a length or lengths of wire, fashioned
into the shape of a quadrant bar, with eyes or loops directed outwardly from
one side of the same, and with an inner end i, for the jointing and connecting of
the same.
The application of my invention to windows, casements or frames, turning upon
hinged joints, affixed to the vertical, horizontal or other sides of a frame, such
as casements, fan-lights, sky-lights, single and double windows and the like, differs
in no essential respect from its application to a side hinged window as described.
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 :-
First In the stay, of a combined window stay and fastener, consisting of a
bar or a quadrant shaped bar or rod, having loops or eyes located upon the same,
at suitable distances apart, whereby a window can be retained open, at positions
corresponding to the said loops or eyes, when one or other of them take upon a
peg or hook of another part, substantially as described and set forth.
Secondly-In the stay, of a combined window stay and fastener, consisting of
a quadrant bar or rod having loops or eyes disposed upon the same, and with
the inner end jointed or attachedly connected and jointed, substantially as described
and set forth.
Thirdly-In a combined casement or window stay and fastener, the combination
with a bar having loops or eyes located at suitable distances along the same, of a
stay and casement or window holding means, substantially as described and set
forth.
Fourthly In a combined casement or window stay and fastener, the com-
bination with an eyed and inwardly jointed stay, of a combined stay holder and
casement or window fastener or catch, substantially as described and set forth.
Dated this 16th day of July 1892.
