PROVISIONAL SPECIFICATION.
Improvements applicable to Window Sashes.
1, THOMAS DOWNIE, of 2 Radnor Terrace, Glasgow, in the County of Lanark,
North Britain, Engineer, do hereby declare the nature of this invention to be
as follows, that is to say :-
My said invention relates to window sashes of kinds arranged both to move
vertically in the ordinary way and to be capable of swinging inwards for cleaning
or other purposes and my object is to improve and simplify the fittings or
furniture required with such sashes.
In carrying out my invention I provide to serve as a hinge or hinges on which
a sash can swing inwards, one or more hinge eyes or hooks, each projecting from a
plate by means of which it is fixed by screws to the sash frame; and for each
such eye or hook I provide a spindle attached by one, or preferably, by two short
webs or parts at right angles to the spindle to a plate which is fixed by screws to
the window frame. When the sash is closed, each eye or hook on it is in position
for its open side to pass over the attaching webs of the spindle when the sash is
moved vertically into the position for being swung inwards; and the sash may be
prevented from being swung inwards excepting when in such position.
The weight of the sash inay be carried in the manner described in my Patent
Specification No. 11138 of 1890; or my improved hinge fittings may be applied in
combination with any other arrangement of the sash for which they may be found
suitable. When in the arrangement of sash adopted the weight cord on one side
has to be disconnected to allow of the sash being swung inwards, I employ an
improved and simplified device for the connection of the weight cord to the sash.
This device consists of a metal fitting which is fixed in a recess formed for it in
the sash frame edge at the lower end of the groove in which the weight cord lies,
this fitting being made with a slot which is narrow at the top and wider at its lower
part.
A knot is formed on the weight cord of a size too large to pass through the
narrow part of the slot but which can be entered through the wider part and
when the cord is placed with its knot in the fitting it securely suspends the sash,
whilst it can be easily removed when the sash is to be swung inwards.
Dated this Twenty-fourth day of June 1892.

COMPLETE SPECIFICATION.
Improvements applicable to Window Sashes.
1, THOMAS DOWNIE, of 2, Radnor Terrace, Glasgow, in the County of Lanark,
North Britain, Engineer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement, that is to say :-
My said invention relates to window sashes of kinds arranged both to move
vertically in the ordinary way, and to be capable of swinging inwards for cleaning
or other purposes; and my object is to improve and simplify the fittings or furniture
required with such sashes.
In carrying out my invention I provide one or more hinge eye-plates or hooks on
the sash frame to engage each with a hinge spindle attached by one or more webs
to a plate on the window frame when the sash is moved vertically into a certain
position and on these the sash can be swung inwards. When the weight cord on one
Cu 027

page_text: side has to be disconnected before swinging the sash, I employ a metal fitting fixed
in a recess in the sash frame edge to hold the cord and from which the cord can
easily be detached when required.
And in order that my said invention and the manner of performing the same
may be properly understood, I hereunto append a sheet of explanatory drawings
to be hereinafter referred, and showing my improvements applicable to window
sashes.
Figures, 1, and, 2, of the drawings are sectional elevations as at right angles to
each other of as much of a window frame, and parts connected therewith, as is
necessary to show the application of my invention.
Figure, 3, is a plan, Figure, 4, is an elevation, and Figure, 5, a vertical section
as at right angles to Figure, 4, of the hinge eye-plate or hook.
Figure, 6, is a plan and Figures, 7, and, 8, are elevations as at right angles to
each other of the hinge spindle and plate.
Figures, 9, 10, and, 11, are respectively similar views of the metal fitting for
retaining the weight cord.
Figure, 12, is a plau, and Figure, 13, a vertical section of a device for securing
the weight cord to the sash.
Figure, 14, is a plan of a catch to suspend the cord after it has been detached
from the sash frame.
In these drawings the same reference letters and numerals are used to mark the
same or like parts wherever they are repeated.
1 provide to serve as a hinge or hinges on which the sash, A, can swing inwards,
two hinge eyes or hooks, B, each projecting from a plate, B 1, by means of which
it is fixed by screws to the sash frame, and for each such eye or hook, B, I provide
a hinge spindle, C, attached preferably by two short webs, or parts, C1, at right
angles to the spindle, to a plate, C 2, which is fixed by screws to the window
frame, D. When the sash, A, is closed, each eye or hook, B, on it is in position
for its open side to pass over the attaching webs, C 1, of the spindle, C, when the
sash is moved vertically into the position for being swung inwards; and the sash
may be prevented if desired from being swung inwards excepting when in such
position.
The weight of the sash, A, may be carried in the manner described in my Patent
Specification No. 11138 of 1890; or my improved hinge fittings may be applied in
combination with any other arrangement of the sash for which they may be found
suitable. When in the arrangement of sash, A, adapted, the weight cord, E, on
one side has to be disconnected to allow of the sash being swung inwards, I employ
an improved and simplified device, F, for the connection of the weight cord to the
sash. This device, I, consists of a metal fitting which is fixed in a recess formed
for it in the sash frame edge, A, at the lower end of the groove, A 1, in which the
weight cord lies, this fitting being made with a slot, F 1, which is narrow at the
top and wider at its lower part. pass the weight cord, E, through a small
aunular device, G, one end of which is formed with a shoulder sufficient to retain
the cord after it has been knotted. This device, G, is made of a size too large to
pass through the narrow part of the slot, F 1, of the metal fitting, F, but it can be
entered through the wider part; and when the cord, E, is placed with the annular
device, G, in the metal fitting, F, it securely suspends the sash, A, whilst it can be
easily removed and be hung from a catch piece, H, provided for the purpose on the
window framing, when the sash is to be swung inwards.
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 :-
1. The improved combination of parts or devices to enable window sashes to be
turned as upon lateral hinges substantially as hereinbefore described and as shown
in the accompanying drawings.
2. Providing a window sash with one or more hinge hooks in combination each

page_text: with a hinge spindle fixed on the window frame substantially as and for the
purposes hereinbefore described and as shown in Figures, 1, to, 8, of the
accompanying drawings.
3. The device for connecting one side of a window sash to the counterweighted
suspending cord and consisting of the metal fitting (F) hereinbefore described and
shown in Figures, 2, 9, 10, and, 11, of the accompanying drawings.
Dated this Tenth day of March 1893.
