"IMPROVEMENTS IN WINDOW OR CASEMENT STAYS OR HOLDERS,"
"
"
In constructing our stay or holder for fixing at the top or bottom of what is
known as the casement of an ordinary hinged or French" window, we employ
two strong metal bars or limbs," by preference of unequal length, say about as
one to three, and we secure one end of each of these by an ordinary joint, with
plate and screws, to the casement, and the frame; generally the longer arm or bar
to the casement, and the shorter arm to the frame; and, the other ends of these
bars we unite or "joint" to each other, in or after the following manner :-we
first enlarge these ends into cheese-shaped bosses, about one inch and a quarter
diameter, to fit, with one side or disc face of each against the other, and, the
uniting or coupling pin or "centre," we construct as a binding screw," with
enlarged "milled or otherwise ornamented "head," for convenience in screwing
and unscrewing.
"
"
The point, or point end, of this screw centre, is screwed into one of the before-
described cheeks or bosses of the middle or uniting joint, and the plain part,
"under the head," passes through the other cheek or boss, and, by means of a
groove round the plain part of this pin, and a "set screw or other equivalent,
through or into the latter named boss, to "take" into this groove, we cause the
act of screwing or unscrewing,-by means of the " screw-head," to either pull
together or to separate, definitely, the before-described central bosses or cheeks.
We now corrugate or indent the inner disc faces of the said pair of bosses, in
either a wave or a straight "zig-zag " line, or as teeth, to fit into each other,
and so that when parted from each other, by the screw, they can be moved, and
will also allow the two other joints to move, freely, and thus allow the window to
be opened or closed; and when, by means of the said screw, the two corrugated,
indented, or toothed surfaces are pressed together or into each other, at any
Dia 1

angle of the joint and bars, and consequently, at any desired position or
opening" of the casement,-the same will be firmly and securely held in that
position.
In some cases, such, for instance, as "sky-lights," or where it may be desirable or
necessary to employ cords or other equivalent means or convenience, for actuating
the "stay" and casement or "light," we sometimes prefer to substitute a metal
slide, in lieu of one of the before-named arms or bars, this being fixed upon the side
of the casement, and one end of the then single or only bar, is jointed to the block
which slides therein; the before-described pair of corrugated or indented bosses,―
considerably enlarged,-being employed at about the centre of the bar,-one upon
and as a part of the same, and the other as a fixture, upon the side of the frame of
the Window or "
sky-light"; and, by bending the upper end of the bar a few
degrees forward,-from the casement, and attaching a cord thereto, the bar
becomes a lever, and the joint or screw at the bosses, its fulcrum, and thus, by a
second cord to actuate the screw (or in some cases a lever and spring) and the
corrugated surfaces of the bosses, the casement or light" may be opened and
secured, ("stayed ") in any desired position, by the cords, or other equivalent which
can reach and similarly actuate the stay or holder and the Casement.
