PROVISIONAL SPECIFICATION.
Improved Devices connected with the Sash Frames of Windows.
I, WILLIAM NICOL of 55 Albert Road, Crosshill in the County of the City
of Glasgow, Joiner, do hereby declare the nature of my invention to be as
follows:-
This invention has reference to improved devices for being applied to the sliding
sash frames of windows with the object of enabling them to be detached and
swivelled within the apartments of buildings and held in position for cleaning or
repair purposes.
The improvements consist all as follows:-
Plates would be secured near the upper and lower ends of one of the sides of the
lower sliding sash frame and these parts would be formed with projecting arms of
kneed or projecting out and down curved shape, so as to enter recessed or slotted
plates screwed to the batten rod opposite these at the level the sash frame is desired
to be swivelled within the apartment. The sash frame would have its hanging
cord detached at the opposite side to that on which the aforesaid fittings are
applied, and on being swivelled out nearly at right angis the kneed arms would
enter the slotted plates and hold the sash frame in position or vice versa the kneed
arms may be fitted inverted ways on the batten rod and the slotted plates be screwed
to the sash frame.
Similar kneed arms would be secured to the side of the upper sash frame, and
on it being swivelled within the apartment at or near the same level as the lower
sash the arms would enter slots or recesses formed in plates screwed to the outer
or adjacent side of the swivelied in lower sash, and by this means the upper as
well as the lower sash frame will be retained in position while it is swivelled within
the apartment.
The ends of the cords or chaius on which the sash frames are hung would be
attached and detached as follows. A plate would be sunk in and screwed to the
upper part of the sides of each sash and it would be formed with a segmental ring
or projecting curved or kneed flanges on each side and an open space or slit in the
centre between these.
Each cord would be drawn through a portable short tube with tapered or narrow
upper part and wider recessed lower part to receive the knotted end of cord. The
upper end of portable tube would be inserted upwards into the kneed or segmental
flanged plate and be held there by the usual counterbalance weights at opposite
end of cord. When the one side of sash frame is desired to be swivelled within
the appartment the portable tube holding the knotted end of cord would be drawn
down and unshipped from its retaining plate and be clipped or slipped into a
corresponding segmental or flanged plate screwed to the fixed frame of window.
The parting bead would be formed in two halves or parts the top part being
fixed and the lower part made portable, so as to enable the top sash to be swivelled
within the apartment.
The portable part would be attached to the fixed part by a dovetail or like joint.
or by an overlapping screwed on plate.

I, WILLIAM NICOL of 55 Albert Road, Crosshill, in the County of the City
of Glasgow, Joiner, do hereby declare the nature of my invention to be as
follows:-
This invention has reference to improved devices for being applied to the sliding
sash frames of windows, with the object of enabling them to be detached and
swivelled within the apartments of buildings and held in position for cleaning or
repair purposes.
And in order that my said invention and the manner of carrying the same into
practice may be properly understood, I have hereunto appended an explanatory
sheet of drawings in which the same reference letters are used to indicate
corresponding parts in all the figures where shown.
Figure 1 is a detached plan view of the lower and upper sash frames of a window
the lower sash frame being fitted with a device like that shown detached in
Figure 3 and the upper sash frame with a device like that shown detached in
Figure 10.
Figure 2 is a similar view to Figure 1 showing the lower and upper sash frames-
as fitted with the devices illustrated detached in Figures 7 and 9 respectively.
Figures 3 to 10 show detached views of modified forms of the devices; and
Figures 11 and 12 show views of the cord detached.

Referring to these drawings:-The improvements consist all as follows:-
Plates a would be screwed or secured near the upper and lower ends of one of
the sides of the lower sliding sash frame A and the plates would be formed. as
shown in Figures 3 and 4, with projecting arms a¹ of kneed or projecting out and
down curved or slotted shape so as to enter recessed or slotted plates 6b screwed
to the batten rod B opposite these at the level the sash frame. A is desired to be
swivelled within the apartment. The sash frame A would have its hanging cord
detached at the opposite side to that on which the aforesaid fittings are applied, and
on being swivelled out nearly at right angles as shown dotted in Figure. 1 the
kneed arm a would enter the slotted plates bb and hold the sash frame A. in.
position, and a hinged bar d may be used to act as a stop for. preventing the
part a' from rising up within the slot b' or vice versa the. kneed. arms a a' may be.
fitted inverted ways on the batten rod B and. the slotted. plates b¹ be screwed to
the sash frame A:
Similar kneed arms would be secured to the side of the upper sash frame A¹³
and on its being swivelled within the apartment at or near.the same level as the
lower sash the arms would enter slots or. recesses: formed in plates screwed to
the outer or adjacent side of the swivelled in lower sash A and by this means the
upper frame A' as well as the lower. sash frame: A will be. retained in position.
while it is swivelled within the apartment.
In the arrangement shown detached in Eigure 10 and as applied to the upper
sash frame A' in Figure 1 the device is shown as formed in three parts a, a', a
hinged together at the ends a³ so that the slitted part of a when the sash A¹ is
swivelled out will enter a slotted part 6 in the plate screwed. to end of lower
sash A. In the arrangement shown detached. in Figure 5, the parts a a¹ are shown.
as connected together by a hinge at a and the slitted part of a¹ is made to enter
a pocket recess secured to the plate b. Figure 6 shows an analogous arrange-
ment to Figure 5. but in which the slitted part of a¹ is placed at top instead of at
bottom, and a projecting bead 6' is used instead of a slot in plate for the former
to fit on to. Figure 7 shows similar views of another modified arrangement of
device and Figure 8 an edge view of same. This is shown applied to the lower
sash frame A in Figure 2. In this arrangement a U shaped plate c is screwed to

page_text: sash frame A and the part a is made to slide within same by taking hold of the
projecting flange at while guide pins c¹ which may be fitted with rollers, will keep
same in proper position.
Figure 9 shows a similar arrangement to Figure 7 and this is shown applied to
the upper sash frame A¹ in Figure 2. In this arrangement the slitted hinge
part a when the sash is swivelled out will enter a slot in a plate 6 screwed to
parting bead or fixed frame of window.
The ends of the cords or chains on which the sash frames are hung would be
attached and detached as follows. A plate e would be sunk in and screwed to the
upper part of the sides of each sash and it would be formed with a segmental ring
or projecting curved or kneed flanges el on each side and an open space or slot e² in
the centre between these. Each cord would be drawn through a portable short
tube with tapered or narrow upper part f and wider recessed lower part f¹ to
receive the knotted end of cord. The upper end of portable tube would be
inserted upwards into the kneed or segmental flanged plate e and be held there by
the usual counterbalance weights at opposite end of cord. When the one side of
sash frame is desired to be swivelled within the apartment the portable tube ff¹
holding the knotted end of cord would be drawn and unshipped from its retaining
plate e and be clipped or slipped into a corresponding segmental or flanged plate
screwed to the fixed frame of window. The parting bead would be formed in two
halves or parts the top part being fixed and the lower part made portable so as
to enable the top sash A¹ to be swivelled within the apartment. The portable
part would be attached to the fixed part by a dovetail or like joint or by an
overlapping screwed on plate.
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 :-
In combination with the sash frames of windows, the construction and use of devices
for enabling said sash frames to be detached and swivelled and held in position
within the apartments of buildings substantially as herein described in reference
to and shown in Figures to 10 of the accompanying drawings.
