PROVISIONAL SPECIFICATION.
Improvements in and relating to Sliding Sash Window Frames.
I, ALEXANDER MACKIE, of 163 Lowwaters, Hamilton, in the County of Lanark,
Joiner and Builder, do hereby declare the nature of my Invention to be as
follows:-
My invention provides for improvements in windows, so that the sashes while
hung with weights, to slide up and down in the usual way, may be also opened
inwards for the purpose of cleaning and repairing same, in a simple and effective
manner without disturbing the batten rods or parting slips.
The sashes are half checked to the sliding stiles and are hinged to the sliding
stile on the one side to open inwards and may be fixed on the other side to the
sliding stile with a lock or latch or other similar contrivance. The sliding stiles are
kept in position by hardwood or metal slips, fixed to stiles, which project on both
sides of the stile and work in longitudinal grooves in outside facings, parting
slips, and batten rods. The sliding stiles are attached to the weights with cord
or chains in the usual way.
The fixed frames for the sashes to work in are made with hollow or box extended
top lintels, so that the lower sash may be raised high enough to admit of the upper
sash opening inwards under same, while the outside facings, parting slips, and
batten rods, have side grooves for the hardwood slips or guides to work in as before
described.
The sashes when locked to their sliding stiles work upwards and downwards in
the usual way.
To open the under sash for cleaning purposes, a hinged bar or stop is turned to
a horizontal position, and the sash raised until it stops against same when it can
then be unlocked and opened inwards.
To open the upper sash, the aforesaid stop or bar is swivelled to its vertical position
on the batten rod, and the under sash is raised up to the top space at lintel and
the upper sash is brought down against a stop when the spring on the sliding stile
will catch in a notch on fixed frame and keep the moveable or sliding stile in
position while this sash is swivelled within the apartment.

Improvements in and relating to Sliding Sash Window Frames.
I, ALEXANDER MACKIE, of 163 Lowwaters, Hamilton, in the County of Lanark,
Joiner and Builder, do hereby declare the nature of my, invention and in what
[Price 8d.]

page_text: manner the same is to be performed to be particularly described and ascertained
in and by the following statement, that is to say:-
My invention provides for improvements in windows, so that the sashes while
hung with weights, to slide up and down in the usual way, may be also opened
inwards for the purpose of cleaning and repairing same, in a simple and effective
manner without disturbing the batten rods or parting slips.
The sashes are half checked to the sliding stiles and are hinged to the sliding
stile on the one side to open inwards and may be fixed on the other side to the
sliding stile with a lock or latch or other similar contrivance. The sliding stiles are
kept in position by hardwood or metal slips, fixed to stiles, which project on both
sides of the stile and work in longitudinal grooves in outside facings, parting
slips, and batten rods. The sliding stiles are attached to the weights with cord
or chains in the usual way.
The fixed frames for the sashes to work in are made with hollow or box extended
top lintels, so that the lower sash may be raised high enough to admit of the upper
sash opening inwards under same, while the outside facings, parting slips, and
batten rods, have side grooves for the hardwood slips or guides to work in as before
described.
The sashes when locked to their sliding stiles work upwards and downwards in
the usual way.
To open the under sash for cleaning purposes, a hinged bar or stop is turned to
a horizontal position, and the sash raised until it stops against same when it can
then be unlocked and opened inwards.
To open the upper sash, the aforesaid stop or bar is swivelled to its vertical position
on the batten rod, and the under sash is raised up to the top space at lintel and
the upper sash is brought down and held in a notch on fixed frame and so keep the
moveable or sliding stile in position while this sash is swivelled within the apart-
ment.
And in order that my said invention and the manner of carrying 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 corre-
sponding parts in the several figures where shown.
Figure 1 shows an elevation of the interior of a window.
Figure 2 is a vertical section showing lower sash thrown up, and upper sash
for cleaning.

Figure 3 is a vertical section showing under, sash open for cleaning.
Figure 4 is a horizontal cross section of frame showing moveable stiles with
sashes rebated and hinged to stiles.
Figure 5 is a detached view of brass plates screwed to ends of moveable stiles.
Figure 6 is a similar view showing brass catches fixed to parting slips, to prevent
moveable stiles from running upwards when the upper sash is open.
Figure 7 is a similar view showing brass stops fixed to batten rods, to prevent
moveable stiles running upwards when under sash is open.
Referring to these drawings:-
a represents moveable stiles.
b shows grooves in batten rods, parting slips and outside facings.
c shows hardwood slips, screwed to moveable stiles a which run in grooves b.
d shows brass plates Figure 5 screwed to moveable stile ends a. These plates d
fill up the vacant part at meeting rails and assist in binding the moveable stiles a
to sash stiles f.
e shows hollow box lintel, where the lower sash is pushed into in order to give
space to open the upper sash under same.
f shows sash stiles hinged to moveable stiles.a.
g shows keyhole for latch or lock.

apartment.
i shows catches fixed to parting slips Figure 6. When upper sash frame is
drawn down and swivelled within apartment this catch automatically oscillates
into a slotted plate in moveable stile, and prevents the latter from being moved
upwards until sash is again swivelled back.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is:-
The constructing and working of sliding sash window frames, so that both sash
frames can be swivelled within the apartment substantially as and in the improved
manner herein described, in reference to and shown in the accompanying drawings.
