Improvements in and in connection with Hinged Sliding Window
Sashes to Open Inwardly.
I, GEORGE CRAIG BROWN, Junr., Upholsterer and Window Blind Maker, 244,
Buchanan Street, Glasgow, do hereby declare the nature of this invention to be
as follows:-
Having regard to my Patent 2863/95, and other similar patents for hinging
lower sliding sashes of windows to open inwardly, I now make the following
improvements. I unship and reship the sash weight automatically by the open-
ing and closing of the sash-thus-I have a metal plate a few inches long
working under a groove in the centre bead and filling the width of sash channell
across to inner bead. This plate at the upper end is kneed or bent round to receive
the cord or chains through a hole at the top under which it is secured by a knot
for cord and a pin for chains. The bottom end of plate is kneed outwards about
half an inch at right angles, and in the sash stile a few inches from top there is
a recess cut across to allow the sash to hook into this kneed projection-thus
connecting the sash with the weight. There is hinged to the inside edge of this
plate a loose flap the length of double the width of the bead or batten rod. This
flap lies on the face of sash top rail when closed, and the bead or batten rod
being severed about the top of sash, and the lower part hinged to turn round,
then when the sash is drawn inwards, it disconnects from the hooked plate and,
pushing forward the hinged flap underneath the upper portion of batten rod or
bead or other projection-thereby arrests and holds the weight, and the sash is
free to open inwards. Then when closing the sash the recess in stile entering
over the hook or knee of plate releives the flap of the sash weight held under
the batten rod or other projection and the flap is turned round into its place on
sash top rail by folding back the bead or batten rod. The sash is now hung on
both sides again, and is free to slide up and down.
To prevent the sash from being accidentally lifted out of slots of my existing
patent hinge I place a bracket projecting about two inches on the part of batten
rod or bead where the top of sash is when in hinge. This bracket is so shaped as
to allow the projecting studs in stile to pass up through it when raising or
lowering the sash. When opening the sash inwards, it comes under the bracket
and cannot be lifted out accidentally.
My second improvement is for the opening inwardly of the upper sliding sash
of windows, and consists of two brackets protruding from the centre bead or
frame about two and half inches with key seated sockets at end to receive keyed
pivots fixed on corresponding places in sash when it is brought down. What
is obtained by the pivot and socket being keyed is security from the sash being
lifted out when turned inwards-the keys being brot. underneath the bottom of
sockets, and what is obtained by the brackets projecting is freedom to open in the
sash at right angles. A portion of the outer bead is releived to allow the sash
to clear. The unreleived portion is left as a guide on sash and gets relief in the
same way by cutting out a corresponding recess in corner of stile. I fold down a

page_text: portion of the middle bead on a pivoted hinge and when this is put back in its
place, is secured by a turn-buckle made from a cotter pin placed through the bead
having the ends folded over at the inside to pass through a slotted plate counter
sunk in the frame. A ring or crank is fixed at the outer end to turn it with to
secure the bead in its place.

1, GEORGE CRAIG BROWN, Jnr., Upholsterer and Window-Blind Maker, of
244, Buchanan Street, Glasgow, 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 window sashes which are adapted to open inwards for
cleaning and other purposes.
The invention, which is an improvement upon my prior Patent No. 2863 of
1895 and other similar patents for hinged windows adapted to open inwardly,
has for its object the automatic shipping and unshipping of the sash weight by
the mere opening and closing of the sash and without any hand manipulation
whatever.
In order that the said invention may be properly understood I have hereunto
appended an explanatory sheet of drawings, whereon,
Fig. 1 is a front view of part of the side stile of a sash frame with my improve-
ments applied thereto, showing the weight unshipped from the window sash.
Fig. 2 is a side view of the frame and sash showing the weight shipped to
the sash.
Fig. 3 is a cross section on the line - Fig. 2.
Fig. 4 is a similar section but showing the sash partly swung inwards.
Fig. 5 is a front view and Fig. 6 a side view of the locking plate.
Fig. 7 is a front view and Fig. 8 a side view of the sash plate.
Fig. 9 is a perspective view and Fig. 10 a side view showing how the sash
plate is fitted in place.
In carrying out my invention I use a metal locking plate a which is a few
inches long and works in the sash channel of the window frame c, between
the parting bead d and the batten rod e. This plate a, at its upper end, is bent
or curved as shown at a and below the bent part is a keyhole slot a for the
reception of the weight cord (or chain) f. If the sash o is suspended by cords and
weights the cord f can be tied into a knot below the curved part a¹ but if it is
suspended by chains, the chain can be secured to the plate a by means of a pin.
The lower end a³ of the plate a is kneed or bent at right angles, as shown, so as to
enter a recess g in the sash stile and thereby lock the plate to the sash.
To the inside edge of the plate a a loose flap h is hinged which, when the
window sash is closed, lies against its top rail.
The batten rod is cut at i, that is, at a point somewhat above the top of the
lower sash and a metal plate j secured to the lower end of the upper part, whilst
the lower part el is hinged so as to turn inwards as shown at Fig. 1.
The sash plate. is made as shown at Figs. 7 and 8 and consists of a cast iron
plate with a tapered upper bead or flange and a lower flange or bead
which
tapers at its underside at and also at its front side face at 1 (see Fig. 3). This

page_text: plate is fitted in a recess cut out at the upper end of the side stile of the sash in
such manner as to lie flush therein (see Figs. 9 and 10).
The knee of the plate a is also tapered at m (see Figs. 5 and 6).
With this arrangement and construction, when the parts are in the normal
working position (Figs. 2 and 3) the lower sash o can be freely moved up and
down in the channel b, the cord f and weight being locked to the sash by the
knee a of the plate a which grips in the recess 7 of the sash. If it is desired to
turn the sash o inwards for cleaning purposes the hinged part e¹ of the batten
rod is turned inwards, as shown at Figs. 1 and 4, and then the sash is swung
inwards upon its hinges, which may be the same as those described in the specifi-
cation of my prior patent aforesaid." The turning inwards of the sash disconnects
the sash plate from the knee a³, and, at the same time, turns back the hinged
flap h into the position Figs. 1 and 4 so that it will catch under the plate j of
the batten rode and thereby prevent the plate a moving upwards under the action
of the weight attached to its cord f. The sash is now free to move inwards whilst
the weight and cord are disengaged and held in place.
Now, when the sash is closed again, the flange of its plate overrides the
tapered end m of the knee a³ and causes the latter to enter the recess g in order
to again lock the plate a to the sash which will be performed whenever the sash
is fully closed. After the sash has been closed it is only necessary to turn in
the batten rod e in order to disengage the flap from the plate j and turn it
in against the sash o. When this has been done the sash is again hung on both
cords and can be worked up and down in the window frame.
In order to prevent the Haph being moved back, by accidentally closing the
batten rod, when the sash is turned inwards, a recess may be left at the back
of the plate so that the flap can enter it and be held locked in place. The bevel Z
on the front end of the flange of the plate k is made sufficient, when overriding
the knee a³, to pull down the plate a slightly and thereby disengage the flap h
from the recess.
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 consider novel and desire to claim is:-
The arrangement whereby the sash weight can be automatically shipped and
unshipped by the mere opening and closing of the window sash, substantially
as hereinbefore described with reference to the drawings annexed.
