PROVISIONAL SPECIFICATION.
Improved Rattling and Draught-preventing Device for Windows.
I, JOHN KINGSMILL, of No. 36, Bournemouth Road, Folkestone, Builder, do
hereby declare the nature of this invention to be as follows:-
This invention relates to an improved rattling and draught-preventing device
for windows, and has for its object to provide a device which shall effectually
prevent a window to which it is applied, rattling and admitting draughts between
the sash and frame, such device being extremely simple in construction, inexpen-
sive of manufacture, and effective in operation.
In carrying my invention into practice I provide a sheet of brass or other suit-
able material, which is stamped or otherwise fashioned in the form of a blank
having a tapering or conical shape.
The edges of the side of the said blank are struck-up to form flanges or raised
rims, the rear portion of such blank also being bent up, preferably at a more
oblique angle and to a greater height than the sides of the blank. The said bent
up or rear portion constitutes a lip for the purpose of enabling the device to be
readily manipulated.
A central longitudinally disposed slot is provided which extends from a point
adjacent to the forward extremity of the device to within a desirable distance of
the rear thereof.
The shank of a headed screw or pin passes through the said slot for the purpose
of fixing the device to the frame of the window, such shank being of a size that
will allow a free sliding movement of the said device.
In operation the device is secured upon the window frame by means of the
screw or its equivalent in such a position as to allow the edge of such device which
is nearest the window sash to abut against the surface of such sash.
By sliding the device downward, it is caused to act as a wedge and press the
window sash firmly against the rear beading of the frame and so prevent the
window rattling and the admission of draughts.
The device is placed out of operation by grasping the lip and sliding the former
upward and then turning it upon the screw or pin so as to cause the diminished
end of such device to be uppermost.

I, JOHN KINGSMILL, of No. 36, Bournemouth Road, Folkestone, Builder, 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 an improved rattling and draught-preventing device
for windows, and has for its object to provide a device which shall effectually pre-
vent a window to which it is applied, rattling and admitting draughts between
the sash and frame, such device being extremely simple in construction, inexpen-
sive of manufacture, and effective in operation.
And in order that this my said invention may be the more readily understood
and carried into practical effect, reference is hereby made to the accompanying
sheet of illustrative drawings, wherein:-
Fig. 1 is a plan view of the device in the "blank" stage, Fig. 2 being an
edge view thereof. Fig. 3 is a side view of the device in its finished state. Fig. 4
a perspective view thereof, and Fig. 5, an elevational view of the device applied
to the frame of a window.
In carrying my invention into practice, I provide a sheet of brass or other suit-
able material, which is stamped or otherwise fashioned in the form of a blank a
having a tapering or wedge shape as shewn by Fig. 1.
The edges of the side of the said blank a are struck-up to form flanges or raised
rims a', the rear portion a² of such blank also being bent up, preferably at a more
oblique angle and to a greater height than the sides a¹ of the blank. The said
bent up or rear portion a constitutes a lip for the purpose of enabling the device
to be readily manipulated as will be hereinafter more fully referred to.
represents a central longitudinally disposed slot which extends from a point
adjacent to the forward extremity of the device to within a desirable distance of
the rear thereof.
The shank of a headed screw or pin c passes through the said slot b for the
purpose of fixing the device to the frame of the window, such shank being of a
size that will allow a free sliding movement of the said device.
In operation the device is secured upon the window frame d by means of the
screw or its equivalent in such a position as to allow the edge of such device
which is nearest the window sash e to abut against the surface of such sash, as
shewn by Fig. 5. By sliding the device downward, it is caused to act as a wedge
and press the window sash firmly against the rear beading f of the frame and so
prevent the window rattling and the admission of draughts.
The device is placed out of operation by grasping the lip a² and sliding the
former upward and then turning it upon the screw or pin c so as to cause the
diminished end of such device to be uppermost.
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 :-
1. The improved rattling and draught-preventing device for windows, consisting
in a tapered plate having raised sides and a lip at the rear, said device having a
longitudinally disposed slot through which a screw or its equivalent passes for
attaching the device to a window frame in a movable manner, substantially as
described and illustrated.
2. In a device for preventing windows rattling and admitting draughts, the

page_text: plate a having raised sides a¹, a rear lip a², and a longitudinal disposed slot b;
in combination with a screw or its equivalent c, all arranged, combined, and
operating substantially in the manner described and as illustrated by the
drawings.
