PROVISIONAL SPECIFICATION.
Improvements connected with Windows.
I, ANDREW BARR of Camphill Cottage, Bothwell, Joiner, do hereby declare
the nature of this invention to be as follows:-
This invention relates to certain improvements on or developments of the invention
set forth in the Specification of my prior Patent No. 15259 of 1891.
In this invention the window sashes are hinged by means of one or more vertical
rods or spindles which pass through eyes secured to the frame or inner beading and
to the sash. A projection or catch is made on the rod. The rod or rods can be
removed when desired.
The upper sash is made to move along with the lower one and turn on the same
hinges by locking it to the lower sash by meaus of catches on the hook and eye
principle. The eyes of these catches are preferably slotted.
The inner beading is preferably hinged at its upper end so as to be capable of
being pulled out of place and it may also be so hinged as to move sideways. The
beading can be locked in place by means of a lever catch or hook working into
a plate with a slot or eye in it.
The parting bead is preferably hinged or pivotted so as to be capable of being
forced backwards into a recess in the frame and lie flush therein so as to enable the
window sash to be turned inwards or this bead may be hinged so as to be capable
of being moved upwards or sideways out of the way of the window.
If desired one of the weights and cords may be dispensed with and a rubber
tyred wheel be used as a substitute. The wheel would be carried in the window
sash or the sash frame.
Instead of using rods for the hinges as hereinbefore mentioned pins or pintles
may be employed.

1, ANDREW BARR, of Camphill Cottage, Bothwell, 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 certain improvements on or developments of the
invention set forth in the Specification of my prior Patent No 15259 of 1891.
And in order that my said invention may be properly understood I have
hereunto appended two explanatory sheets of drawings, whereon.

Referring to the drawings whereon the same reference letters wherever repeated
indicate the same or similar parts.
In this invention the lower window sash a is hinged to one side of the window
frame by means of eyes i, i¹, secured to the sash and a vertical rod e, which passes
through the eyes. i, ¹, and also through eyes j, j, secured to the batten rod
9 or to
the window frame. The lower eye j' is a socket eye and retains the rod e in
position. A projecting leaff is made on the rod and this leaf, which has a nick f¹
cut in it, see Figs. 8 and 8ª, is capable of catching on a screw or projection k on
the sash stile.
The lower sash, which is hung as usual on chains or cords, is provided at the
left hand side, with a cord or chain detaching device consisting of a plate catch
(see also enlarged views Figs. 3 and 4) which is countersunk flush into the left
hand stile of the sash and is provided with a hinged flap having a rectangular
hole in it. Attached to the chain m is a link n (see also Fig. 6) having a
hook n at its lower end which can be engaged with the hole 12 of the flap.
A locking pin o is also attached to the link by a short length of chain. The chain
or cord is connected to the sash by engaging the book n' of the link n with the
hinged flap as shown at Fig. 1. With this device, when it is desired to dis-
connect the sash a from the chain m, the pin o is first passed through a hole in the
link n and into a hole in the stile of the window frame so as to lock said link to
the frame and prevent the weight falling down, thereafter the sash.a is raised
slightly and the flap disengaged from the hook n' of the link and bent down on
top of the sash as shown at Fig. 2. The window a can now be swung inwards free
of the chain m which is, held in position by the pin o as shown at Fig. 2. The
chain m can be again connected to the sash a by first engaging the hook n¹ with
the flap and then withdrawing the pin o.
If desired the plate 7 may be of the form shown at
one piece without a hinged flap and having a slot
hole 1. To connect the catch n of the link, which
upwards, it is merely necessary to slip it into the slot
the hole 12.

In some cases, when cords are used, it may be advisable to make the linkin as
shown at Fig. 6. m² is the cord. which is merely tied to the eye m² at the upper
end of the link.
In Fig. 7 a link hook n is shown bent rectangularly at each end so that the
cord m can be attached in a line with the flap and the edge of 'the
window sash.
The upper sash b, which can be hung in the usual manner or in the manner
described in the Specification of my prior Patent aforesaid, is, preferably, made to
move along with and turn on the same hinge as the lower sash a by locking it
thereto by means of catches on the hook and eye principle. These catches may
consist of screws p, p, inserted in the upper rail of the top sash and slotted

page_text: catches, secured to the upper rail of the lower sash. As will be seen in the
enlarged side and plan views at Figs. 9 and 10 each catch 7, 4', is shaped and
has a bayonet slot 2 in its upwardly bent part q³.
The inner left hand beading (not shown at Figs. 1 and 2 but at Fig. 14) is
preferably hinged or screw pivotted at its upper end so as to be capable of being
pulled out of place and it may also be so hinged as to move sideways. This
beading can be locked in place by means of a pivotted lever catch or hook s
(see Figs. 11 and 12) working into a plate t having a slot in it and secured
over a recess in the window casing. The full lines Fig. 11, show the catch
locked into the plate t whilst the dotted lines show the catch released.
The left hand side parting bead is, preferably, hinged or pivotted- so as to be
capable of being forced backwards into a recess in the frame in such a manner as
to lie flush therein in order to enable the window sash to be turned inwards; or
this bead may be hinged so as to be capable of being moved upwards or sideways
out of the way of the window.
If desired the weight and cord at the left hand side of the window can be
dispensed with and a rubber tyred wheel, such as shown at u. Fig. 13, be used as
a substitute. The wheel is carried in a bracket u' fitted in a recess at the top
left hand corner of the window sash a; or it may be fitted in the sash frame.
With this invention, when it is desired to clean the windows, the batten rod hat
the left hand side of the window is unlocked by releasing the catchs and is the
drawn aside out of the way. The lower sash is then pushed up until the screw k
comes a little above the dotted position shown at k Fig. 1 when the rod e and its
leaf fare turned round to the position shown in full lines at Figs. 2, 8, and 8ª, and
dotted lines at Fig. 1, the sash can now be lowered again until the screw k catches
in the nick f of the leaf as shown at Figs. 8 and 2. The link n is now disengaged
from the flap and the chain m locked to the frame or casing by the pin o as shown
at Fig. 2. The lower sash can now be swung inwards readily turning on the rod e
and supported by the leaff and eyes i, i¹ as shown at Fig. 2.
In order to clean the upper sash it is lowered until the screws p, p', enter the
slots 2 of the catches g, g', of the lower sash, the left hand parting bead is then
taken out or forced backwards into a recess in the frame and the left hand cord.
disengaged; preferably in the manner described in the Specification of my prior
Patent aforesaid, or the sash may have a plate and the cord a hook link as
hereinbefore described as for the lower sash. The two sashes can now be swung
inwards together turning on the same pivot rod e as shown at Fig. 2. This enables the
outside of the upper sash to be cleaned and the inside can be cleaned in the usual
manner without swinging it inwards.
If desired (as shown at Fig. 14) two or more flaps or wings f can be made on the
rode and the eyes i, ¹, on the sash dispensed with. In this case two screws or
catches are provided one for each leaff. With this arrangement the sash, when
hinged, is, by means of the screws, connected to and supported by the leaves fon
the rod e which latter turns pivot wise in the eyes j,j. The sash a is shown
at Fig. 14 as raised up sufficiently for the screws to rest on the leaves. When
the window is not hinged the leaves of the rod e are turned round out of the
way of
the screws k.
Fig. 15 shows a form of hook 2 which can be used instead of the screws k, it
catches on the leaves f.
In order to prevent the accidental disengagement of the catches k and leaves
by the raising of the sash, when it is being cleaned, I provide pins v (see Fig. 14)
which can be passed through or under the leaves and into holes made in the sash ;
or, as shown at Figs. 16 and 17, a form of locking catch may be used. This
catch consists of a stud fitted in the sash and which is provided with a turnable
head or button baving a bent arm kou it which can be turned round to the position
shown in full lines in these figures so as to lock into a slot cut in the bent end f³
made on the leaf f.
If desired a pivot rod such as e can be used for both sashes.

page_text: The rod e (or rods) can be removed when desired. One rod e can be used for a
number of windows.
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 :-
1. For windows, the combination of eyes secured to the frame or batten rod and
eyes or equivalent secured to the sash, a rod passed through the eyes on both the
frame and the sash and serving as a spindle or pivot on which the window sash can
be turned, and one or more leaves or projections fitted on the rod and serving to
support the sash when being turned, substantially as herein before described with
reference to the drawings annexed.
2. The method of locking the upper sash to the lower sash by means of catches
so that both sashes can be turned inwards on the same hinge, substantially as
herein before described with reference to the drawings annexed.
3. The modified arrangement shown at Fig. 14 of the annexed drawings wherein
the eyes j, j, are alone used and the rod e is provided with two projections or
leaves and the sash with two catches k, substantially as hereinbefore set forth.
4. The general arrangement and combination of parts of the hinged window,
substantially as herein before described and shown on the drawings annexed.
