Improvements in Windows.
I CHARLES REID of 48 Esslemont Avenue, Aberdeen, Joiner, 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 relates to an improved window, and its object is to render the
cleaning of the outside of the glass, a convenient and safe process, the top and
bottom sashes turning down inwards to a horizontal position. To effect this,
oblong shaped metal pivots, but having the ends rounded, are fixed on the pulley
stiles, at a suitable height above the sill, and metal plates suitably formed to
receive and turn on them, fixed on the sash stiles at the lower end, so that when
the sashes are required to be opened, the top one is pulled down till it comes into
contact with the pivots. The bottom sash is connected with the pivots in the
same manner, but it must first be raised above them, in order that the said pivots
may be reversed. When the sashes have thus been brought into contact with,
the pivots, the beading may then be opened, and the sashes turned down inwards
to a horizontal position. In turning they become locked with the pivots, and are
released again by being replaced vertically in the frame. While being cleaned,
the inner end of the sashes can be rested on a support.
As much of the parting bead as allows the top sash to be taken out and in, is;
hinged, and part, or the whole of the inside bead is also hinged, ordinary hinges
being used, but on each of these parts there is one specially constructed hinge.,
These special hinges are provided with a projection at the centre, on the ball,
against which a spring presses, this keeps the beading closed, thus serving the,
double purpose of a hinge and fastener combined. The parting bead has a grooved.
metal plate sunk in the edge, by which means it can be pulled open, while the
inside bead is pulled open by means of a flush pull fixed on the face.
The sash stiles are rebated on the outside edge to receive the pulley cord, nearly
the whole length of the stile, the pulley cord being connected with the sash by a
screw at the lower end of the rebate. When chain is used, it can be connected
with the sash by means of a metal plate, having a stud formed on it, fixed at the
lower end of the rebate, instead of the screw. This allows the sash to be opened
without disconnecting the weights. The pulley stiles are rebated to receive the
parting bead when open, the stiles of the bottom sash being so much broader than
those of the top sash. The pulley stiles may be formed in one thickness, or have
the piece put on to form the rebate.
In order that this invention may be more clearly understood, reference is had to
the accompanying sheets of drawings, in which
Fig. 1 is a vertical section showing sashes turned down inside.
Figs. 2 & 3 are detail views of the pivots of top and bottom sashes.
Fig. 4 shows sectional plan of sash and frame.
Fig. 5 shows detail view of special hinge for keeping the inside beading closed.
Fig. 6 is flush pull to be fixed on inside bead, and
Fig. 7 is grooved plate, sunk in edge of parting bead.
A is frame of the window, provided with weights a, and pulley stile A'. B is
top sash stile, and B' bottom sash stile, both rebated to receive pulley cord, as
shown at c Figs. 1 & 4, and 6 is fillet to exclude draught. C shows parting bead,
and D inside bead, both fitted with the special hinges E & E¹ Figs. 4 & 5.
y shows position of pulleys in Fig. 1. f is pivot on which the top sash turns,

page_text: shown at Fig. 2, and fis pivot on which bottom sash turns, both pivots being
alike, only that pivot f¹ at Fig. 3 has reversable plate. H is hole through which
pivot passes into pulley stile A¹ when reversed. à is the plate of top sash, which
turns on pivot f, and e the plate of bottom sash turning on pivot f¹. Hinge E
has a projecting part 1, against which spring m presses, hinge E¹ has also a
projecting part j and spring k. The cavity may be dispensed with, when
sufficient room is provided for the weight a, in the wall.
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 :-
G
(1.) An improved window in which oblong shaped pivots, but having the ends
rounded, are fixed on the pulley stiles, at a suitable height above the sill, (the
bottom sash pivot being reversable,) and plates suitably formed to receive and
turn on them, fixed on the sash stiles at the lower end, so that the top and bottom
sashes, on being brought into contact with these pivots, can be turned down inwards
to a horizontal position. In turning they become locked with the pivots, and are
released again by being replaced vertically in the frame, substantially as described
and shown, and for the purposes specified.
(2.) An improved window having sliding sashes, which can be turned down to
a horizontal position, on oblong shaped pivots, but having the ends rounded,
without detaching the weights. These sashes when closed, are held in position by
means of parting beads, and inside beads, the parts of which that are hinged
have one specially constructed hinge on each. These special hinges are provided
with a projecting part at the centre, on the ball, against which a spring presses,
this keeps the beading closed, thus serving the double purpose of a hinge and
fastener combined, substantially as described and shown, and for the purposes
:specified.
(3.) In an improved window the employment of a grooved plate sunk in the
edge of the parting bead, and a flush pull fixed on the face of the inside bead, by
means of which grooved plate, and flush pull, the parts on which they are fixed
can be pulled open, substantially as described and shown, and for the purposes
specified.
