PROVISIONAL SPECIFICATION.
Improvements in Windows.
I, PETER GLEN, of 27 Watt Street, Glasgow, Commission Agent do hereby
declare the nature of this invention to be as follows:-
This invention relates to windows and it has for its object to so construct them
that they can be readily and easily cleaned from the inside of the room.
In carrying out my invention I fit on each of the window sashes, at each side, a
pivot or pin. These pivots are free to slide, when the sashes are raised or lowered,
in grooves or slots cut or made in the stiles of the window frame. The pivots or
pins are, preferably, fitted at or about the centre of the window sashes so that they
can be easily turned or swung on them. The grooves or slots are also of such
a length that when the sashes are being swung inwards for cleaning purposes the
pivots or pins rest on and are supported at their lower ends.
The cords, which are fitted to the sashes at or about their centre and at or near
or to the pivots or pins, are passed up the grooves or slots in the stiles and then in
through oblique holes to the back of the stiles. The cords are then passed up to
the top of the stiles where they are or may be led over guide pulleys and then over
the usual pulleys. Weights are attached to the cords in the usual manner.
To enable the sashes to be turned or swung inwards on the pivots or pins, the
inner and middle beadings are or may be cut so as to be easily taken out of
place. If desired the beadings may be hinged. The outer beadings may be partly
cut away.
The grooves or slots serve as guides to the window when being raised and
lowered.
When it is desired to clean the window all that is necessary is to first remove the
inner beadings and then raise the lower sash slightly so that its bottom rail may
clear the window frame, then lower the sash again until its pivots, at each side, rest
at the bottom of the grooves or slots in the stiles. The sash can now be easily
turned on the pivots and be swung downwards into the horizontal position ready for
cleaning. The top sash is operated in the same manner.
As the cords are within the grooves or slots they do not prevent the sashes being
turned freely on the pivots.

Improvements in Windows.
I, Peter Glen, formerly of 27 Watt Street, Glasgow, and now of 117 Ard-
gowan Street, Glasgow, Commission 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 relates to windows and it has for its object to so construct them
that they can be readily and easily cleaned from the inside of the room.
In carrying out my invention I fit on each of the window sashes, at each side, a
pivot or pin.

page_text: These pivots are free to slide, when the sashes are raised or lowered, in grooves or
slots cut or made in the stiles of the window frame. The pivots or pins are,
preferably, fitted at or about the centre of the window sashes so that they can be
easily turned or swung on them. The grooves or slots are also of such a length
that when the sashes are being swung inwards for cleaning purposes the pivots or
pins rest on and are supported at their lower ends.
The cords, which are fitted to the sashes at or about their centre and at or near
to the pivots or pins, are passed up the grooves or slots in the stiles, and then in
through oblique holes to the back of the stiles.
The cords are then passed up to the top of the stiles where they are led over
guide pulleys. Weights are attached to the cords in the usual manner.
To enable the sashes to be turned or swung inwards on the pivots or pins,
the inner and middle beadings are or may be cut so as to be easily taken out
of place. If desired the beadings may be hinged. The outer beadings may be
partly cut away.
•
The grooves or slots serve as guides to the window when being raised and
lowered.
And in order that my said invention, may be properly understood I have
hereunto appended an explanatory sheet of drawings, whereon,
Fig. 1 is a front elevation of the window and its frame.
Fig. 2 is a side view.
Fig. 3 is a vertical section through the frame, the window sashes being
removed.
Fig. 4 is a similar section but with the sashes in place and turned inwards for
cleaning.
Figs. 5, 5, 6, 64, 7 and 7ª are respectively front and side views of guide
pulleys.
Figs. 8, 9, 10 and 11 are detail views.
Referring to the drawings whereon the same reference letters wherever repeated
indicate the same parts.
a is the upper sash and 6 the lower one. c is the frame. On each side of the
window sashes a casting or stamping d (see also Figs. and 10), having an
outwardly projecting pin or pivot e, is secured. These pivots, when the window
sashes are raised or lowered, slide in the vertical grooves or slots ff' cut in the
side stiles of the frame. The pivots e, as shown, are, preferably, fitted at or about
the centre of the sashes a, b, so that they can be easily turned or swung on them.
The grooves, f¹ are also of such length that when the sashes are swung inwards
for cleaning purposes the pivots e rest on and are supported by the bottom part of
the grooves.
The cords g, g', the ends of which are secured in short grooves in each sash,
are passed through curved slots or openings o cut or made in the castings d, (see
Fig. 10) and then up the grooves for f1 as the case may be. The cords of the
upper sash a are passed through oblique holes i to the back of the stiles where
they pass over the guide pulleys ; and then up over tandem guide pulleys k. The
cords of the lower sash 6 are passed through oblique holes to the back of the
stiles, then between tandem guide pulleys and also, if desired over the tandem
pulleys ko. Weights m are attached to the cords in the usual manner.
Figs. 5, 54, 6, 64, 7 and 74 show to an enlarged scale the special forms of guide
pulley I use with the window. The pulley k (or k°) illustrated at Figs. 5 and 5^ is
a double pulley with the wheels k¹, k³, arranged one below the other tandem wise.
Both the wheels are mounted in a single frame the face plate of which is slotted
at to enable the cord to be threaded on the upper wheel k¹. As shown the upper
wheel k is of larger diameter than the lower one. Both wheels are fitted in the
frame, as shown, at a suitable distance back from the face plate.
The pulley j, illustrated at Figs. 6 and 6^ is a single pulley mounted in a frame
the face plate of which is cut open or slotted at its lower end for the passage of
the cord.

page_text: The tandem pulley j¹ illustrated at Figs. 7 and 7 differs from the pulley k in
that both wheels are of the same diameter and the face plate is cut open or
slotted at its lower end at j³ for the passage of the cord g' over the lower
wheel.
The tandem pulleys may, if desired, be substituted by single pulleys, similar
toj Figs. 6, 6A or vice versa. The tandem pulleys may or may not be used as
occasion or the construction of the window may require.
As will be seen the inner beading n is cut at n¹, n² and the cut out part p, is
hinged to the stiles at n³, n'. The middle or parting bead is also cut at ql and the
cut out part q is or may be hinge-jointed together at q', q' in order that it can be
folded down out of the way. The outer beads may be cut entirely away from
the point.
When it is desired to clean the window all that is necessary is to first turn back
the part p, of the inner bead into the position shown at Figs. 3 and 4 and then
raise the lower sash b slightly so that its bottom rail may clear the window sill and
the hand can be passed underneath so as to pull down the folding centre bead 9 out
of the way. The sash b is then lowered until its pivots e rest on the bottoms of
the grooves. The sash can now be easily and safely swung inwards, turning on
the pivots e, to any desired position ready for cleaning. The upper sash is merely
lowered until its pivots rest on the bottoms of the grooves f, when it can be turned
or swung inwards in like manner.
1
As the cords g, g', at each side are within the grooves f, f' they do not prevent
the sashes being freely turned on the pivots.
In order to lock each hinged bead p in the closed position when the window is
shut, a screw pins (Fig. 8) provided with a ring or knob at its outer end can be-
passed through it into the stile. The ring may lie in a countersunk hole in the
bead as indicated in dotted lines at Fig. 1.
Having now particularly described and ascertained the nature of my said inven-.
declare that what I
tion, and in what manner the same is to be performed,
consider novel and desire to claim is :-
1. The general arrangement and combination of parts of the improved window,.
substantially as hereinbefore described and shown on the drawings annexed.
2. The combination with sashes having pivots or pins at each side, of stiles
having vertical grooves or slots in which said pivots or pins can slide, substantially
as hereinbefore described with reference to the drawings, annexed.
3. The combination with a window constructed and operating substantially as
herein before described, of the special forms of guide pulley, substantially as.
described with reference to Figs. 5, 5ª, 6, 6ª, 7 and 7A of the drawings annexed.
